GREEK AGE OF INQUIRY.

RISE AND DECLINE OF PHYSICAL SPECULATION.

In Chapter II. I have described the origin and decline of Greek Mythology; in this, I am to relate the first European attempt at philosophizing. The Ionian systems spring directly out of the contemporary religious opinions, and appear as a phase in Greek comparative theology.

Contrasted with the psychical condition of India, we cannot but be struck with the feebleness of these first European efforts. They correspond to that period in which the mind has shaken off its ideas of sorcery, but has not advanced beyond geocentral and anthropocentral conceptions. As is uniformly observed, as soon as man has Its imperfections. collected what he considers to be trustworthy data, he forthwith applies them to a cosmogony, and develops pseudo-scientific systems. It is not until a later period that he awakens to the suspicion that we have no absolute knowledge of truth.

The reader, who might, perhaps, be repelled by the apparent worthlessness of the succession of Greek opinions now to be described, will find them assume an interest, if considered in the aggregate, or viewed as a series of steps or stages of European approach to conclusions long before arrived at in Egypt and India. Far in advance of anything that Greece can offer, the intellectual history of India furnishes systems at once consistent and imposing—systems not remaining useless speculations, but becoming inwoven in social life.

Greek philosophy is considered as having originated with Thales, who, though of Phoenician descent, was born at Miletus, a Greek colony in Asia Minor, about B.C. 640. At that time, as related in the last chapter, the Egyptian ports had been opened to foreigners by Psammetichus. In the civil war which that monarch had been waging with his colleagues, he owed his success to Ionian and other Greek mercenaries whom he had employed; but, though proving victor in the contest, his political position was such as to compel him to depart from the maxims followed in his country for so many thousand years, and to permit foreigners to have access to it. Hitherto the Europeans had been only known to the Egyptians as pirates and cannibals.

From the doctrine of Thales, it may be inferred that, though he had visited Egypt, he had never been in communication with its sources of learning, but had merely mingled among the vulgar, from whom he had gathered the popular notion that the first principle is water. The state of things in Egypt suggests that this primitive dogma of European philosophy was a popular notion in that country. With but little care on the part of men the fertilizing Nile-water yielded those abundant crops which made Egypt the granary of the Old World. It might therefore be said, both philosophically and facetiously, that the first principle Importance of water in Egypt. of all things is water. The harvests depended on it, and, through them, animals and man. The government of the country was supported by it, for the financial system was founded on a tax paid by the proprietors of the land for the use of the public sluices and aqueducts. There was not a peasant to whom it was not apparent that water is the first principle of all things, even of taxation; and, since it was not only necessary to survey lands to ascertain the surface that had been irrigated, but to redetermine their boundaries after the subsidence of the flood, even the scribes and surveyors might concede that geometry itself was indebted for its origin to water.

If, therefore, in any part of the Old World, this doctrine had both a vulgar and a philosophical significance, that country was Egypt. We may picture to ourselves the inquisitive but ill-instructed Thales carried in some pirate-ship or trading-bark to the mysterious Nile, respecting which Ionia was full of legends and myths. He saw the aqueducts, canals, flood-gates, the great Lake Moeris, dug by the hand of man as many ages before his day as have elapsed from his day to ours; he saw on all sides the adoration paid to the river, for it had actually become deified; he learned from the vulgar, with whom alone he came in contact, their universal belief that all things arise from water—from the vulgar alone, for, had he ever been taught by the priests, we should have found traces in his system of the doctrines of emanation, transmigration, and absorption, which were imported into Greece in later times. We may interpret the story of Thales on the principles which would apply in the case of some intelligent Indian who should find his way to the outposts of a civilized country. Imperfectly acquainted with the language, and coming in contact with the lower class alone, he might learn their vulgar philosophy, and carry back the fancied treasure to his home.

As to the profound meaning which some have been disposed to extract from the dogma of Thales, we shall, perhaps, be warranted in rejecting it altogether. It has been affirmed that he attempted to concentrate all supernatural powers in one; to reduce all possible agents to unity; in short, out of polytheism to bring forth monotheism; to determine the invariable in the variable; and to ascertain the beginning of things: that he observed how infinite is the sea; how necessary moisture is to growth; nay, even how essential it was to the well-being of himself; "that without moisture his own body would not have been what it was, but a dry husk falling to pieces." Nor can we adopt the opinion that the intention of Thales was to establish a coincidence between philosophy and the popular theology as delivered by Hesiod, who affirms that Oceanus is one of the parent-gods of Nature. The imputation of irreligion made against him shows at what an early period the antagonism of polytheism and scientific inquiry was recognized. But it is possible to believe that all things are formed out of one primordial substance, without denying the existence of a creative power. Or, to use the Indian illustration, the clay may not be the potter.

Thales is said to have predicted the solar eclipse which terminated a battle between the Medes and Lydians, but it has been suggestively remarked that it is not stated that he predicted the day on which it should occur. He had an idea that warmth originates from or is nourished by humidity, and that even the sun and stars derived their aliment out of the sea at the time of their rising and setting. Indeed, he regarded them as living beings; obtaining an argument from the phenomena of amber and the magnet, supposed by him to possess a living soul, because they have a moving force. Moreover, he taught that the whole world is an insouled thing, and that it is full of dÆmons. Thales had, therefore, not completely passed out of the stage of sorcery.

His system obtained importance not only from its own plausibility, but because it was introduced under favourable auspices and at a favourable time. It came into Asia Minor as a portion of the wisdom of Egypt, and therefore with a prestige sufficient to assure for it an attentive reception. But this would have been of little avail had not the mental culture of Ionia been advanced to a degree suitable for offering to it conditions of development. Under such circumstances the Egyptian dogma formed the starting-point for a special method of philosophizing.

The manner in which that development took place illustrates the vigour of the Grecian mind. In Egypt a doctrine might exist for thousands of years, protected by its mere antiquity from controversy or even examination, and hence sink with the lapse of time into an ineffectual and lifeless state; but the same doctrine brought into a young community full of activity would quickly be made productive and yield new results. As seeds taken from the coffins of mummies, wherein they have been shut up for thousands of years, when placed under circumstances favourable for development in a rich soil, and supplied with moisture, have forthwith, even in our own times, germinated, borne flowers, and matured new seeds, so the rude philosophy of Thales passed through a like development. Its tendency is shown in the attempt it at once made to describe the universe, even before the parts thereof had been determined.

But it is not alone the water or ocean that seems to be infinite, and capable of furnishing a supply for the origin of all other things. The air, also, appears to reach as far as the stars. On it, as Anaximenes of Miletus remarks, "the very earth itself floats like a broad leaf." Accordingly, this Ionian, stimulated doubtless by the hope of sharing in or succeeding to the celebrity that Thales had enjoyed for a century, proposed to substitute for water, as the primitive source of things, atmospheric air. And, in truth, there seem to be reasons for bestowing upon it such a pre-eminence. To those who have not looked closely into the matter, it would appear that water itself is generated from it, as when clouds are formed, and from them rain-drops, and springs, and fountains, and rivers, and even the sea. He also attributes infinity to it, a dogma scarcely requiring any exercise of the imagination, but being rather the expression of an ostensible fact; for who, when he looks upward, can discern the boundary of the atmosphere. It is also the soul. Anaximenes also held that even the human soul itself is nothing but air, since life consists in inhaling and exhaling it, and ceases as soon as that process stops. He taught also that warmth and cold arise from mere rarefaction and condensation, and gave as a proof the fact that when we breathe with the lips drawn together the air is cold, but it becomes warm when we breathe through the widely-opened mouth. Hence he concluded that, with a sufficient rarefaction, air might turn into fire, and that this probably was the origin of the sun and stars, blazing comets, and other meteors; but if by chance it should undergo condensation, it would turn into wind and clouds, or, if that operation should be still more increased, into water, snow, hail, and, at last, even into earth itself. And since it is seen from the results of The air is God. breathing that the air is a life-giving principle to man, nay, even is actually his soul, it would appear to be a just inference that the infinite air is God and that the gods and goddesses have sprung from it.

Such was the philosophy of Anaximenes. It was the beginning of that stimulation of activity by rival schools which played so distinguished a part in the Greek intellectual movement. Its superiority over the doctrine of Thales evidently consists in this, that it not only assigns a primitive substance, but even undertakes to show by observation and experiment how others arise from it, and transformations occur. As to the discovery of the obliquity of the ecliptic by the aid of a gnomon attributed to Anaximenes, it was merely a boast of his vainglorious countrymen, and altogether beyond the scientific grasp of one who had no more exact idea of the nature of the earth than that it was "like a broad leaf floating in the air."

The doctrines of Anaximenes received a very important development in the hands of Diogenes of Apollonia, who asserted that all things originate from one essence, which, undergoing continual changes, becoming different at different times, turns back again to the same state. He regarded the entire world as a living being, spontaneously evolving and transforming itself, and agreed with Anaximenes that the soul of man is nothing but air, as is also the soul of the world. From this it follows that the air must be eternal, imperishable, and endowed with consciousness. "It knows much; for without reason it would be impossible for all to be arranged so duly and proportionately as that all should maintain its fitting measure, winter and summer, night and day, the rain, the wind, and fair weather; and whatever object we consider will be found to have been ordered in the best and most beautiful manner possible." "But that which has knowledge is that which men call air; it is it that regulates and governs all, and hence it is the use of air to pervade all, and to dispose all, and to be in all, for there is nothing that has not part in it."

The early cultivator of philosophy emerges with difficulty from fetichism. The harmony observed among the parts of the world is easily explained on the hypothesis of a spiritual principle residing in things, and arranging them by its intelligent volition. It is not at once that he rises to the conception that all this beauty and harmony are due to the operation of law. We are so prone to judge of the process of external things from the modes of our own personal experience, our acts being determined by the exercise of our wills, that it is with difficulty we disentangle ourselves from such notions in the explanation of natural phenomena. Fetichism may be observed in the infancy of many of the natural sciences. Thus the electrical power of amber was imputed to a soul residing in that substance, a similar explanation being also given of the control of the magnet over iron. The movements of the planetary bodies, Mercury, Venus, Mars, were attributed to an intelligent principle residing in each, Astronomy and chemistry have passed beyond the fetich stage. guiding and controlling the motions, and ordering all things for the best. It was an epoch in the history of the human mind when astronomy set an example to all other sciences of shaking off its fetichism, and showing that the intricate movements of the heavenly bodies are all capable not only of being explained, but even foretold, if once was admitted the existence of a simple, yet universal, invariable, and eternal law.

Not without difficulty do men perceive that there is nothing inconsistent between invariable law and endlessly varying phenomena, and that it is a more noble view of the government of this world to impute its order to a penetrating primitive wisdom, which could foresee consequences throughout a future eternity, and provide for them in the original plan at the outset, than to invoke the perpetual intervention of an ever-acting spiritual agency for the purpose of warding off misfortunes that might happen, and setting things to rights. Chemistry furnishes us with a striking example—an example very opportune in the case we are considering—of the doctrine of Diogenes of Apollonia, that the air is actually a spiritual being; for, on the discovery of several of the gases by the earlier experimenters, they were not only regarded as of a spiritual nature, but actually received the name under which they pass to this day, gheist or gas, from a belief that they were ghosts. If a labourer descended into a well and was suffocated, as if struck dead by some invisible hand; if a lamp lowered down burnt for a few moments with a lurid flame, and was then extinguished; if, in a coal mine, when the unwary workman exposed a light, on a sudden the place was filled with flashing flames and thundering explosions, tearing down the rocks and destroying every living thing in the way, often, too, without leaving on the dead any marks of violence; what better explanation could be given of such catastrophes than to impute them to some supernatural agent? Nor was there any want, in those times, of well-authenticated stories of unearthly faces and forms seen in such solitudes.

The modification made by Diogenes in the theory of Anaximenes, by converting it from a physical into a psychological system, is important, as marking the beginning of the special philosophy of Greece. The investigation of the intellectual development of the universe led the Greeks to the study of the intellect itself. In his special doctrine, Diogenes imputed the changeability of the air to its mobility; a property in which he thought it excelled all other substances, because it is among the rarest or thinnest of the elements. It is, however, said by some, who are disposed to transcendentalize his doctrine, that he did not mean the common atmospheric air, but something more attenuated and warm; and since, in its purest state, it constitutes the most perfect intellect, inferior degrees of reason must be owing to an increase of its density and moisture. Upon such a principle, the whole earth is animated by the breath of life; the souls of brutes, which differ from one another so much in intelligence, are only air in its various conditions of moisture and warmth. He explained the production of the world through condensation of the earth from air by cold, the warmth rising upward and forming the sun; in the stars he thought he recognized the respiratory organs of the world. From the preponderance of moist air in the constitution of brutes, he inferred that they are like the insane, incapable of thought, for thickness of the air impedes respiration, and therefore quick apprehension. From the fact that plants have no cavities wherein to receive the air, and are altogether unintelligent, he was led to the principle that the thinking power of man arises from the flowing of that substance throughout the body in the blood. He also explained the superior intelligence of men from their breathing a purer air than the beasts, which carry their nostrils near the ground. In these crude and puerile speculations we have the beginning of mental philosophy.

I cannot dismiss the system of the Apollonian without setting in contrast with it the discoveries of modern science respecting the relations of the air. Toward the world of life it stands in a position of wonderful interest. Decomposed into its constituents by the skill of chemistry, it is no longer looked upon as a homogeneous body; its ingredients have not only been separated, but the functions they discharge have been ascertained. From one of these, carbonic acid, all the various forms of plants arise; that substance being decomposed by the rays of the sun, and furnishing to vegetables carbon, their chief solid ingredient. All those beautifully diversified organic productions, from the mosses of the icy regions to the palms characteristic of the landscapes of the tropics—all those we cast away as worthless weeds, and those for the obtaining of which we Inter-dependence of animals and plants. expend the sweat of our brow—all, without any exception, are obtained from the atmosphere by the influence of the sun. And since without plants the life of animals could not be maintained, they constitute the means by which the aËrial material, vivified, as it may be said, by the rays of the sun, is conveyed even into the composition of man himself. As food, they serve to repair the waste of the body necessarily occasioned in the acts of moving and thinking. For a time, therefore, these ingredients, once a part of the structure of plants, enter as essential constituents in the structure of animals. Yet it is only in a momentary way, for the essential condition of animal activity is that there shall be unceasing interstitial death; not a finger can be lifted without the waste of muscular material; not a thought arise without the destruction of cerebral substance. From the animal system the products of decay are forthwith removed, often by mechanisms of the most exquisite construction; but their uses are not ended, for sooner or later they find their way back again into the air, and again serve for the origination of plants. It is needless to trace these changes in all their details; the same order or cycle of progress holds good for the water, the ammonia; they pass from the inorganic to the living state, and back to the inorganic again; now the same particle is found in the air next aiding in the composition of a plant, then in the body of an animal, and back in the air once more. In this perpetual Agency of the sun. revolution material particles run, the dominating influence determining and controlling their movement being in that great centre of our system, the sun. From him, in the summer days, plants receive, and, as it were, store up that warmth which, at a subsequent time, is to reappear in the glow of health of man, or to be rekindled in the blush of shame, or to consume in the burning fever. Nor is there any limit of time. The heat we derive from the combustion of stubble came from the sun as it were only yesterday; but that with which we moderate the rigour of winter when we burn anthracite or bituminous coal was also derived from the same source in the ultra-tropical climate of the secondary times, perhaps a thousand centuries ago.

In such perpetually recurring cycles are the movements of material things accomplished, and all takes place under the dominion of invariable law. The air is the source whence all organisms have come; it is the receptacle to which they all return. Its parts are awakened into life, not by the influence of any terrestrial agency or principle concealed in itself, as Diogenes supposed, but by a star which is ninety millions of miles distant, the source, direct or indirect, of every terrestrial movement, and the dispenser of light and life.

To Thales and Diogenes, whose primordial elements were water and air respectively, we must add Heraclitus of Ephesus, who maintained that the first principle is fire. He illustrated the tendency which Greek philosophy had already assumed of opposition to Polytheism and the idolatrous practices of the age. It is said that in his work, ethical, political, physical, and theological subjects were so confused, and so great was the difficulty of understanding his meaning, that he obtained the surname of "the Obscure." In this respect he has had among modern metaphysicians many successors. He founds his system, however, upon the simple axiom that "all is convertible into fire, and fire into all." Perhaps by the term fire he understood what is at present meant by heat, for he expressly says that The fictitious permanence of successive forms. he does not mean flame, but something merely dry and warm. He considered that this principle is in a state of perpetual activity, forming and absorbing every individual thing. He says, "All is, and is not; for though it does in truth come into being, yet it forthwith ceases to be." "No one has ever been twice on the same stream, for different waters are constantly flowing down. It dissipates its waters and gathers them again; it approaches and recedes, overflows and fails." And to teach us that we ourselves are changing and have changed, he says, "On the same stream we embark and embark not, we are and we are not." By such illustrations he implies that life is only an unceasing motion, and we cannot fail to remark that the Greek turn of thought is fast following that of the Hindu.

But Heraclitus totally fails to free himself from local conceptions. He speaks of the motion of the primordial principle in the upward and downward directions, in the higher and lower regions. He says that the chief accumulation thereof is above, and the chief deficiency below: and hence he regards the soul of a man as a portion of fire migrated from heaven. He carries his ideas of the transitory nature of all phenomena to their last consequences, and illustrates the noble doctrine that all which appears to us to be permanent is only a regulated and self-renewing concurrence of similar and opposite motions by such extravagances as that the sun is daily destroyed and renewed.

In the midst of many wild physical statements many true axioms are delivered. "All is ordered by reason and intelligence, though all is subject to Fate." Already he perceived what the metaphysicians of our own times are illustrating, that "man's mind can produce no certain knowledge from its own interior resources alone." He regarded the organs of sense as being the channels through which the outer life of the world, and therewith truth, enters into the mind, and that in sleep, when the organs of sense are closed, we are shut out from all communion with the surrounding universal spirit. In his view every thing is animated and insouled, but to different degrees, organic objects being most completely or perfectly so. His astronomy may be anticipated from what has been said respecting the sun, which he moreover regarded as being scarcely more than a foot in diameter, and, like all other celestial objects, a mere meteor. His moral system was altogether based upon the physical, the fundamental dogma being the excellence of fire. Thus he accounted for the imbecility of the drunkard by his having a moist soul, and drew the inference that a warm or dry soul is the wisest and best; with justifiable patriotism asserting that the noblest souls must belong to a climate that is dry, intending thereby to indicate that Greece is man's fittest and truest country. There can be no doubt that in Heraclitus there is a strong tendency to the doctrine of a soul of the world. If the divinity is undistinguishable from heat, whither can we go to escape its influences? And in the restless activity and incessant changes it produces in every thing within our reach, do we not recognize the tokens of the illimitable and unshackled?

I have lingered on the chief features of the early Greek philosophy as exhibited in the physical school of Ionia. They serve to impress upon us its intrinsic imperfection. It is a mixture of the physical, metaphysical, and mystical which, upon the whole, has no other value than this, that it shows how feeble were the beginnings of our knowledge—that we commenced with the importation of a few vulgar errors from Egypt. In presence of the utilitarian philosophy of that country and the theology of India, how vain and even childish are these germs of science in Greece! Yet this very imperfection is not without its use, since it warns us of the inferior position in which we stand as respects the time of our civilization when compared with those ancient states, and teaches us to reject the assertion which so many European scholars have wearied themselves in establishing, that Greece led the way to all human knowledge of any value. Above all, it impresses upon us more appropriate, because more humble views of our present attainments and position, and gives us to understand that other races of men not only preceded us in intellectual culture, but have equalled, and perhaps surpassed every thing that we have yet done in mental philosophy.

Of the other founders of Ionic sects it may be observed that, though they gave to their doctrines different forms, the method of reasoning was essentially the same in them all. Of this a better illustration could not be given than in the philosophy of Anaximander of Miletus, who was contemporary with Thales. He started with the postulate that things arose by separation from a universal mixture of all: his primordial principle was therefore chaos, though he veiled it in the metaphysically obscure designation "The Infinite." The want of precision in this respect gave rise to much difference of opinion as to his tenets. To his chaos he imputed an internal energy, by which its parts spontaneously separated from each other; to those parts he imputed absolute unchangeability. He taught that the earth is of a cylindrical form, its base being one-third of its altitude; it is retained in the centre of the world by the air in an equality of distance from all the boundaries of the universe; that the fixed stars and planets revolved round it, each being fastened to a crystalline ring; and beyond them, in like manner, the moon, and, still farther off, the sun. He Origin of cosmogony. conceived of an opposition between the central and circumferential regions, the former being naturally cold, and the latter hot; indeed, in his opinion, the settling of the cold parts to the centre, and the ascending of the hot, gave origin, respectively, to the formation of the earth and shining celestial bodies, the latter first existing as a complete shell or sphere, which, undergoing destruction, broke up into stars. Already we perceive the tendency of Greek philosophy to shape itself into systems of cosmogony, founded upon the disturbance Origin of biology. of the chaotic matter by heat and cold. Nay, more, Anaximander explained the origin of living creatures on like principles, for the sun's heat, acting upon the primal miry earth, produced filmy bladders or bubbles, and these, becoming surrounded with a prickly rind, at length burst open, and, as from an egg, animals came forth. At first they were ill-formed and imperfect, but subsequently elaborated and developed. As to man, so far from being produced in his perfect shape, he was ejected as a fish, and under that form continued in the muddy water until he was capable of supporting himself on dry land. Besides "the Infinite" being thus the cause of generation, it was also the cause of destruction: "things must all return whence they came, according to destiny, for they must all, in order of time, undergo due penalties and expiations of wrong-doing." This expression obviously contains a moral consideration, and is an exemplification of the commencing feeble interconnection between physical and moral philosophy.

As to the more solid discoveries attributed to this philosopher, we may dispose of them in the same manner that we have dealt with the like facts in the biographies of his predecessors—they are idle inventions of his vainglorious countrymen. That he was the first to make maps is scarcely consistent with the well-known fact that the Egyptians had cultivated geometry for that express purpose thirty centuries before he was born. As to his inventing sun-dials, the shadow had gone back on that of Ahaz a long time before. In reality, the sun-dial was a very ancient Oriental invention. And as to his being the first to make an exact calculation of the size and distance of the heavenly bodies, it need only be remarked that those who have so greatly extolled his labours must have overlooked how incompatible such discoveries are with a system which assumes that the earth is cylindrical in shape, and kept in the midst of the heavens by the atmosphere; that the sun is farther off than the fixed stars; and that each of the heavenly bodies is made to revolve by means of a crystalline wheel.

The philosopher whose views we have next to consider is Anaxagoras of Clazomene, the friend and master of Pericles, Euripides, and Socrates. Like several of his predecessors, he had visited Egypt. Among his disciples were numbered some of the most eminent men of those times.

The fundamental principle of his philosophy was the recognition of the unchangeability of the universe as a whole, the variety of forms that we see being produced by new arrangements of its constituent parts. Such a doctrine includes, of course, the idea of the eternity of matter. Anaxagoras says, "Wrongly do the Greeks suppose that aught begins or ceases to be, for nothing comes into being or is destroyed, but all is an aggregation or secretion of pre-existent things, so that all becoming might more correctly be called becoming-mixed, and all corruption becoming-separate." In such a statement we cannot fail to remark that the Greek is fast passing into the track of the Egyptian and the Hindu. In some respects his views recall those of the chaos of Anaximander, as when he says, "Together were The primal intellect. all things infinite in number and smallness; nothing was distinguishable. Before they were sorted, while all was together, there was no quality noticeable." To the first moving force which arranged the parts of things out of the chaos, he gave the designation of "the Intellect," rejecting Fate as an empty name, and imputing all things to Reason. He made no distinction between the Soul and Intellect. His tenets evidently include a dualism indicated by the moving force and the moved mass, an opposition between the corporeal and mental. This indicated that for philosophy there are two separate routes, the physical and intellectual. While Reason is thus the prime mover in his philosophy, he likewise employed many subordinate agents in the government of things—for instance, air, water, and fire, being evidently unable to explain the state of nature in a satisfactory way by the Cosmogony of Anaxagoras. operation of the Intellect alone. We recognize in the details of his system ideas derived from former ones, such as the settling of the cold and dense below, and the rising of the warm and light above. In the beginning the action of Intellect was only partial; that which was primarily moved was only imperfectly sorted, and contained in itself the capability of many separations. From this point his system became a cosmogony, showing how the elements and fogs, stones, stars, and the sea, were produced. These explanations, as mighty be anticipated, have no exactness. Among his primary elements are many incongruous things, such as cold, colour, fire, gold, lead, corn, marrow, blood, &c. This doctrine implied that in compound things there was not a formation, but an arrangement. It required, therefore, many elements instead of a single one. Flesh is made of fleshy particles, bones of bony, gold of golden, lead of leaden, wood of wooden, &c. These analogous constituents are homoeomeriÆ. Of an infinite number of kinds, they composed the infinite all, which is a mixture of them. From such conditions Anaxagoras proves that all the parts of an animal body pre-exist in the food, and are merely collected therefrom. As to the phenomena of life, he explains it on his doctrine of dualism between mind and matter; he teaches that sleep is produced by the reaction of the latter on the former. Even plants he regards as only rooted animals, motionless, but having sensations and desires; he imputes the superiority of man to the mere fact of his having hands. He explains our mental perceptions upon the hypothesis that we have naturally within us the contraries of all the qualities of external things; and that, when we consider an object, we become aware of the preponderance of those qualities in our mind which are deficient in it. Hence all sensation is attended with pain. His doctrine of the production of animals was founded on the action of the sunlight on the miry earth. The earth he places in the centre of the world, whither it was carried by a whirlwind, the pole being originally in the zenith; but, when animals issued from the mud, its position was changed by the Intellect, so that there might be suitable climates. In some particulars his crude guesses present amusing anticipations of subsequent discoveries. Thus he maintained that the moon has mountains, and valleys like the earth; that there have been grand epochs in the history of our globe, in which it has been successively modified by fire and water; that the hills of Lampsacus would one day be under the sea, if time did not too soon fail.

As to the nature of human knowledge, Anaxagoras, asserted that by the Intellect alone do we become acquainted with the truth, the senses being altogether untrustworthy. He illustrated this by putting a drop of coloured liquid into a quantity of clear water, the eye being unable to recognize any change. Upon such principles also he asserted that snow is not white, but black, since it is composed of water, of which the colour is black; and hence he drew such conclusions as that "things are to each man according as they seem to him." It was doubtless the recognition of the unreliability of the senses that extorted from him the well-known complaint: "Nothing can be known; nothing can be learned; nothing can be certain; sense is limited; intellect is weak; life is short."

The biography of Anaxagoras is not without interest. Born in affluence, he devoted all his means to philosophy, and in his old age encountered poverty and want. He was accused by the superstitious Athenian populace of Atheism and impiety to the gods, since he asserted that the sun and moon consist of earth and stone, and that the so-called divine miracles of the times were nothing more than common natural effects. For these reasons, and also because of the Magianism of his doctrine—for he taught the antagonism of mind and matter, a dogma of the detested Persians—he was thrown into prison, condemned to death, and barely escaped through the influence of Pericles. He fled to Lampsacus, where he ended his days in exile. His vainglorious countrymen, however, conferred honour upon his memory in their customary exaggerated way, boasting that he was the first to explain the phases of the moon, the nature of solar and lunar eclipses, that he had the power of foretelling future events, and had even predicted the fall of a meteoric stone.

From the biography of Anaxagoras, as well as of several of his contemporaries and successors, we may learn that a popular opposition was springing up against philosophy, not limited to a mere social protest, but carried out into political injustice. The antagonism between learning and Polytheism was becoming every day more distinct. Of the philosophers, some were obliged to flee into exile, some suffered death. The natural result of such a state of things was to force them to practise concealment and mystification, as is strikingly shown in the history of the Pythagoreans.

Of Pythagoras, the founder of this sect, but little is known with certainty; even the date of his birth is contested, probably he was born at Samos about B.C. 540. If we were not expressly told so, we should recognize from his doctrines that he had been in Egypt and India. Some eminent scholars, who desire on all occasions to magnify the learning of ancient Europe, depreciate as far as they can the universal testimony of antiquity that such was the origin of the knowledge of Pythagoras, asserting that the constitution of the Egyptian priesthood rendered it impossible for a foreigner to become initiated. They forget that the ancient system of that country had been totally destroyed in the great revolution which took place more than a century before those times. If it were not explicitly stated by the ancients that Pythagoras lived for twenty-two years in Egypt, there is sufficient internal evidence in his story to prove that he had been there a long time. As a connoisseur can detect the hand of a master by the style of a picture, so one who has devoted attention to the old systems of thought sees, at a glance, the Egyptian in the philosophy of Pythagoras.

He passed into Italy during the reign of Tarquin the Proud, and settled at Crotona, a Greek colonial city on the Bay of Tarentum. At first he established a school, but, favoured by local dissensions, he gradually organized from the youths who availed themselves of his instructions a secret political society. Already it had passed into a maxim among the learned Greeks that it is not advantageous to communicate knowledge too freely to the people—a bitter experience in persecutions seemed to demonstrate that the maxim was founded on truth. The step from a secret philosophical society to a political conspiracy is but short. Pythagoras appears to have taken it. The disciples who were admitted to his scientific secrets after a period of probation and process of examination constituted a ready instrument of intrigue against the state, the issue of which, after a time, appeared in the supplanting of the ancient senate and the exaltation of Pythagoras and his club to the administration of government. The actions of men in all times are determined by similar principles; and as it would be now with such a conspiracy, so it was then; for, though the Pythagorean influence spread from Crotona to other Italian towns, an overwhelming reaction soon set in, the innovators were driven into exile, their institutions destroyed, and their founder fell a victim to his enemies.

The organization attempted by the Pythagoreans is an exception to the general policy of the Greeks. The philosophical schools had been merely points of reunion for those entertaining similar opinions; but in the state they can hardly be regarded as having had any political existence.

It is difficult, when the political or religious feelings of men have been engaged, to ascertain the truth of events in which they have been concerned; deception, and falsehood, seem to be licensed. In the midst of the troubles befalling Italy as the consequence of these Pythagorean machinations, it is impossible to ascertain facts with certainty. One party exalts Pythagoras to a superhuman state; it pictures him majestic and impassive, clothed in robes of white, with a golden coronet around his brows, listening to the music of the spheres, or seeking relaxation in the more humble hymns of Homer, Hesiod, and Thales; lost in the contemplation of Nature, or rapt in ecstasy in his meditations on God; manifesting his descent from Apollo or Hermes by the working of miracles, predicting future events, conversing with genii in the solitude of a dark cavern, and even surpassing the wonder of speaking simultaneously in different tongues, since it was established, by the most indisputable testimony, that he had accomplished the prodigy of being present with and addressing the people in several different places at the same time. It seems not to have occurred to his disciples that such preposterous assertions cannot be sustained by any evidence whatsoever; and that the stronger and clearer such evidence is, instead of supporting the fact for which it is brought forward, it the more serves to shake our confidence in the truth of man, or impresses on us the conclusion that he is easily lead to the adoption of falsehood, and is readily deceived by imposture.

By his opponents he was denounced as a quack, or, at the best, a visionary mystic, who had deluded the young with the mummeries of a free-masonry; had turned the weak-minded into shallow enthusiasts and grim ascetics; and as having conspired against a state which had given him an honourable refuge, and brought disorder and bloodshed upon it. Between such contradictory statements, it is difficult to determine how much we should impute to the philosopher and how much to the trickster. In this uncertainty, the Pythagoreans reap the fruit of one of their favourite maxims, "Not unto all should all be made known." Perhaps at the bottom of these political movements lay the hope of establishing a central point of union for the numerous Greek colonies of Italy, which, though they were rich and highly civilized, were, by reason of their isolation and antagonism, essentially weak. Could they have been united in a powerful federation by the aid of some political or religious bond, they might have exerted a singular influence on the rising fortunes of Rome, and thereby on humanity.

The fundamental dogma of the Pythagoreans was that "number is the essence or first principle of things." This led them at once to the study of the mysteries of figures and of arithmetical relations, and plunged them into the wildest fantasies when it took the absurd form that numbers are actually things. The approval of the doctrines of Pythagoras so generally expressed was doubtless very much due to the fact that they supplied an intellectual void. Those who had been in the foremost ranks of philosophy had come to the conclusion that, as regard external things, and even ourselves, we have no criterion of truth; but in the properties of numbers and their relations, such a criterion does exist.

It would scarcely repay the reader to pursue this system in its details; a very superficial representation of it is all that is necessary for our purpose. It recognizes two species of numbers, the odd and even; and since one, or unity, must be at once both odd and even, it must be the very essence of number, and the ground of all other numbers; hence the meaning of the Pythagorean expression, "All comes from one;" which also took form in the mystical allusion, "God embraces all and actuates all, and is but one." To the number ten extraordinary importance was imputed, since it contains in itself, or arises from the addition of, 1, 2, 3, 4—that is, of even and odd numbers together; hence it received the name of the grand tetractys, because it so contains the first four numbers. Some, however, assert that that designation was imposed on the number thirty-six. To the triad the Pythagoreans likewise attached much significance, since it has a beginning, a middle, and an end. To unity, or one, they gave the designation of the even-odd, asserting that it contained the property both of the even and odd, as is plain from the fact that if one be added to an even number it becomes odd, but if to an odd number it becomes even. They arranged the primary elements of nature in a table of ten contraries, of which the odd and even are one, and light and darkness another. They said that "the nature and energy of number may be traced not only in divine and dÆmonish things, but in human works and words everywhere, and in all works of art and in music." They even linked their arithmetical views to morality, through the observation that numbers never lie; that they are hostile to falsehood; and that, therefore, truth belongs to their family: their fanciful speculations led them to infer that in the limitless or infinite, falsehood and envy must reign. From similar reasoning, they concluded that the number one contained not only the perfect, but also the imperfect; hence it follows that the most good, most beautiful, and most true are not at the beginning, but that they are in the process of time evolved. They held that whatever we know must have had a beginning, a middle, and an end, of which the beginning and end are the boundaries or limits; but the middle is unlimited, and, as a consequence, may be subdivided ad infinitum. They therefore resolved corporeal existence into points, as is set forth in their maxim that "all is composed of points or spacial units, which, taken together, constitute a number." Such being their ideas of the limiting which constitutes the extreme, they understood by the unlimited the intermediate space or interval. By the aid of these intervals they obtained a conception of space; for, since the units, or monads, as they were also called, are merely geometrical points, no number of them could produce a line, but by the union of monads and intervals conjointly a line can arise, and also a surface, and also a solid. As to the interval thus existing between monads, some considered it as being mere aËrial breath, but the orthodox regarded it as a vacuum; hence we perceive the meaning of their absurd affirmation that all things are produced by a vacuum. As it is not to be overlooked that the monads are merely mathematical points, and have no dimensions or size, substances actually contain no matter, and are nothing more than forms.

The Pythagoreans applied these principles to account for the origin of the world, saying that, since its very existence is an illusion, it could not have any origin in time, but only seemingly so to human thought. As to time itself, they regarded it as "existing only by the distinction of a series of different moments, which, however, are again restored to unity by the limiting moments." The diversity of relations we find in the world they supposed to be occasioned by the bond of harmony. "Since the principles of things are neither similar nor congenerous, it is impossible for them to be brought into order except by the intervention of harmony, whatever may have been the manner in which it took place. Like and homogeneous things, indeed, would not have required harmony; but, as to the dissimilar and unsymmetrical, such must necessarily be held together by harmony if they are to be contained in a world of order." In this manner they confused together the ideas of number and harmony, regarding the world not only as a combination of contraries, but as an orderly and harmonical combination thereof. To particular numbers they therefore imputed great significance, asserting that "there are seven chords or harmonies, seven pleiads, seven vowels, and that certain parts of the bodies of animals change in the course of seven years." They carried to an extreme the numerical doctrine, assigning certain numbers as the representatives of a bird, a horse, a man. This doctrine may be illustrated Modern Pythagorisms in chemistry. by facts familiar to chemists, who, in like manner, attach significant numbers to the names of things. Taking hydrogen as unity, 6 belongs to carbon, 8 to oxygen, 16 to sulphur. Carrying those principles out, there is no substance, elementary or compound, inorganic or organic, to which an expressive number does not belong. Nay, even an archetypal form, as of man or any other such composite structure, may thus possess a typical number, the sum of the numbers of its constituent parts. It signifies nothing what interpretation we give to these numbers, whether we regarded them as atomic weights, or, declining the idea of atoms, consider them as the representatives of force. As in the ancient philosophical doctrine, so in modern science, the number is invariably connected with the name of a thing, of whatever description the thing may be.

The grand standard of harmonical relation among the Pythagoreans was the musical octave. Physical qualities, such as colour and tone, were supposed to appertain to the surface of bodies. Of the elements they enumerated five—earth, air, fire, water, and ether, connecting therewith the fact that man has five organs of sense. Of the planets they numbered five, which, together with the sun, moon, and earth, are placed apart at distances determined by a musical law, and in their movements through space give rise to a sound, the harmony of the spheres, unnoticed by us because we habitually hear it. They place the sun Pythagorean physics and psychology. in the centre of the system, round which, with the other planets, the earth revolves. At this point the geocentric doctrine is being abandoned and the heliocentric takes its place. As the circle is the most perfect of forms, the movements of the planets are circular. They maintained that the moon is inhabited, and like the earth, but the people there are taller than men, in the proportion as the moon's periodic rotation is greater than that of the earth. They explained the Milky Way as having been occasioned by the fall of a star, or as having been formerly the path of the sun. They asserted that the world is eternal, but the earth is transitory and liable to change, the universe being in the shape of a sphere. They held that the soul of man is merely an efflux of the universal soul, and that it comes into the body from without. From dreams and the events of sickness they inferred the existence of good and evil dÆmons. They supposed that souls can exist without the body, leading a kind of dream-life, and identified the motes in the sunbeam with them. Their heroes and dÆmons were souls not yet become embodied, or who had ceased to be so. The doctrine of transmigration which they had adopted was in harmony with such views, and, if it does not imply the absolute immortality of the soul, at least asserts its existence after the death of the body, for the disembodied spirit becomes incarnate again as soon as it finds a tenement which fits it. To their life after death the Pythagoreans added a doctrine of retributive rewards and punishments, and, in this respect, what has been said of animals forming a penitential mechanism in the theology of India and Egypt, holds good for the Pythagoreans too.

Of their system of politics nothing can now with certainty be affirmed beyond the fact that its prime element was an aristocracy; of their rule of private life, but little beyond its including a recommendation of moderation in all things, the cultivation of friendship, the observance of faith, and the practice of self-denial, promoted by ascetic exercises. It was a maxim with them that a right education is not only of importance to the individual, but also to the interests of the state. Pythagoras himself, as is well known, paid much attention to the determination of extension and gravity, the ratios of musical tones, astronomy, and medicine. He directed his disciples, in their orgies or secret worship, to practise gymnastics, dancing, music. In correspondence with his principle of imparting to men only such knowledge as they were fitted to receive, he communicated to those who were less perfectly prepared exoteric doctrines, reserving the esoteric for the privileged few who had passed five years in silence, had endured humiliation, and been purged by self-denial and sacrifice.

We have now reached the consideration of the Eleatic philosophy. It differs from the preceding in its neglect of material things, and its devotion to the supra-sensible. It derives its name from Elea, a Greek colonial city of Italy, its chief authors being Xenophanes, Parmenides, and Zeno.

Xenophanes was a native of Ionia, from which having been exiled, he appears to have settled at last in Elea, after leading for many years the life of a wandering rhapsodist. He gave his doctrines a poetical form for the purpose of more easily diffusing them. To the multitude he became conspicuous from his opposition to Homer, Hesiod, and other popular poets, whom he denounced for promoting the base polytheism of the times, and degrading the idea of the divine by the immoralities they attributed to the gods. He proclaimed God as an all-powerful Being, existing from eternity, and without any likeness to man. A strict monotheist, he denounced the plurality of gods as an inconceivable error, asserting that of the all-powerful and all-perfect there could not, in the nature of things, be more than one; for, if there were only so many as two, those attributes could not apply to one of them, much less, then, if there were many. This one principle or power was to him the same as the universe, the substance of which, having existed from all eternity, must necessarily be identical with God; for, since it is impossible that there should be two Omnipresents, so also it is impossible that there should be two Eternals. It therefore may be said that there is a tincture of Orientalism in his ideas, since it would scarcely be possible to offer a more succinct and luminous exposition of the pantheism of India.

The reader who has been wearied with the frivolities of the Ionian philosophy, and lost in the mysticisms of Pythagoras, cannot fail to recognize that here we have something of a very different kind. To an Oriental dignity of conception is added an extraordinary clearness and precision of reasoning.

To Xenophanes all revelation is a pure fiction; the discovery of the invisible is to be made by the intellect of man alone. The vulgar belief which imputes to the Deity the sentiments, passions, and crimes of man, is blasphemous and accursed. He exposes the impiety of those who would figure the Great Supreme under the form of a man, telling them that if the ox or the lion could rise to a conception of the Deity, they might as well embody him under their own shape; that the negro represents him with a flat nose and black face; the Thracian with blue eyes and a ruddy complexion. "There is but one God; he has no resemblance to the bodily form of man, nor are his thoughts like ours." He taught that God is without parts, and throughout alike; for, if he had parts, some would be ruled by others, and others would rule, which is impossible, for the very notion of God implies his perfect and thorough sovereignty. Throughout he must be Reason, and Intelligence, and Omnipotence, "ruling the universe without trouble by Reason and Insight." He conceived that the Supreme understands by a sensual perception, and not only thinks, but sees and hears throughout. In a symbolical manner he represented God as a sphere, like the heavens, which encompass man and all earthly things.

In his natural philosophy it is said that he adopted the four elements, Earth, Air, Fire, Water; though by some it is asserted that, from observing fossil fish, on the tops of mountains, he was led to the belief that the earth itself arose from water; and generally, that the phenomena of nature originate in combinations of the primary elements. From such views he inferred that all things are necessarily transitory, and that men, and even the earth itself, must pass away. As to the latter, he regarded it as a flat surface, the inferior region of which extends indefinitely downward, and so gives a solid foundation. His physical views he, however, held with a doubt almost bordering on scepticism: "No mortal man ever did, or ever shall know God and the universe thoroughly; for, since error is so spread over all things, it is impossible for us to be certain even when we utter the true and the perfect." It seemed to him hopeless that man could ever ascertain the truth, since he has no other aid than truthless appearances.

I cannot dismiss this imperfect account of Xenophanes, who was, undoubtedly, one of the greatest of the Greek philosophers, without an allusion to his denunciation of Homer, and other poets of his country, because they had aided in degrading the idea of the Divinity; and also to his faith in human nature, his rejection of the principle of concealing truth from the multitude, and his self-devotion in diffusing it among all at a risk of liberty and life. He wandered from country to country, withstanding polytheism to its face, and imparting wisdom in rhapsodies and hymns, the form, above all others, calculated most quickly in those times to spread knowledge abroad. To those who are disposed to depreciate his philosophical conclusions, it may be remarked that in some of their most striking features they have been reproduced in modern times, and I would offer to them a quotation from the Some of his thoughts reappear in Newton. General Scholium at the end of the third book of the Principia of Newton: "The Supreme God exists necessarily, and by the same necessity he exists always and everywhere. Whence, also, he is all similar, all eye, all ear, all brain, all arm, all power to perceive, to understand, and to act, but in a manner not at all human, not at all corporeal; in a manner utterly unknown to us. As a blind man has no idea of colours, so have we no idea of the manner by which the all-wise God perceives and understands all things. He is utterly void of all body and bodily figure, and can therefore neither be seen, nor heard, nor touched, nor ought to be worshipped under the representation of any corporeal thing. We have ideas of his attributes, but what the real substance of anything is we know not."

To the Eleatic system thus originating with Xenophanes is to be attributed the dialectic phase henceforward so prominently exhibited by Greek philosophy. It abandoned, for the most part, the pursuits which had occupied the Ionians—the investigation of visible nature, the phenomena of material things, and the laws presiding over them; conceiving such to be merely deceptive, and attaching itself to what seemed to be the only true knowledge—an investigation of Being and of God. By the Eleats, since all change appeared to be an impossibility, the phenomena of succession presented by the world were Parmenides on reason and opinion. regarded as a pure illusion, and they asserted that Time, and Motion, and Space are phantasms of the imagination, or vain deceptions of the senses. They therefore separated reason from opinion, attributing to the former conceptions of absolute truth, and to the latter imperfections arising from the fictions of sense. It was on this principle that Parmenides divided his work on "Nature" into two books, the first on Reason, the second on Opinion. Starting from the nature of Being, the uncreated and unchangeable, he denied altogether the idea of succession in time, and also the relations of space, and pronounced change and motion, of whatever kind they Philosophy becoming Pantheism. may be, mere illusions of opinion. His pantheism appears in the declaration that the All is thought and intelligence; and this, indeed, constitutes the essential feature of his doctrine, for, by thus placing thought and being in parallelism with each other, and interconnecting them by the conception that it is for the sake of being that thought exists, he showed that they must necessarily be conceived of as one.

Such profound doctrines occupied the first book of the poem of Parmenides; in the second he treated of opinion, which, as we have said, is altogether dependent on the senses, and therefore untrustworthy, not, however, that it must necessarily be absolutely false. It is scarcely possible for us to reconstruct from the remains of his works the details of his theory, or to show his approach to the Ionian doctrines by the assumption of the existence in nature of two opposite species—ethereal fire and heavy night; of an equal proportion of which all things consist, fire being the true, and night the phenomenal. From such an unsubstantial and delusive basis it would not repay us, even if we had the means of accomplishing it, to give an exposition of his physical system. In many respects it degenerated into a wild vagary; as, for example, when he placed an overruling dÆmon in the centre of the phenomenal world. Nor need we be detained by his extravagant reproduction of the old doctrine of the generation of animals from miry clay, nor follow his explanation of the nature of man, who, since he is composed of light and darkness, participates in both, and can never ascertain absolute truth. By other routes, and upon far less fanciful principles, modern philosophy has at last come to the same melancholy conclusion.

The doctrines of Parmenides were carried out by Zeno the Eleatic, who is said to have been his adopted son. He brought into use the method of refuting error by the reductio ad absurdum. His compositions were in prose, and not in poetry, as were those of his predecessors. As it had been the object of Parmenides to establish the existence of "the One," it was the object of Zeno to establish the non-existence of "the Many." Agreeably to such principles, he started from the position that only one thing really exists, and that all others are mere modifications or appearances of it. He denied motion, but admitted the appearance of it; regarding it as a name given to a series of conditions, each of which is necessarily rest. This dogma against the possibility of motion he maintained by four arguments; the second of them is the celebrated Achilles puzzle. It is thus stated: "Suppose Achilles to run ten times as fast as a tortoise, yet, if the tortoise has the start, Achilles can never overtake him; for, if they are separated at first by an interval of a thousand feet, when Achilles has run these thousand feet the tortoise will have run a hundred, and when Achilles has run these hundred the tortoise will have got on ten, and so on for ever; therefore Achilles may run for ever without overtaking the tortoise." Such were his arguments against the existence of motion; his proof of the existence of One, the indivisible and infinite, may thus be stated: "To suppose that the one is divisible is to suppose it finite. If divisible, it must be infinitely divisible. But suppose two things to exist, then there must necessarily be an interval between those two—something separating and limiting them. What is that something? It is some other thing. But then if not the same thing, it also must be separated and limited, and so on ad infinitum. Thus only one thing can exist as the substratum for all manifold appearances." Zeno furnishes us with an illustration of the fallibility of the indications of sense in his argument against Protagoras. It may be here introduced as a specimen of his method: "He asked if a grain of corn, or the ten thousandth part of a grain, would, when it fell to the ground, make a noise. Being answered in the negative, he further asked whether, then, would a measure of corn. This being necessarily affirmed, he then demanded whether the measure was not in some determinate ratio to the single grain; as this could not be denied, he was able to conclude, either, then, the bushel of corn makes no noise on falling, or else the very smallest portion of a grain does the same."

To the names already given as belonging to the Eleatic school may be added that of Melissus of Samos, who also founded his argument on the nature of Being, deducing its unity, unchangeability, and indivisibility. He denied, like the rest of his school, all change and motion, regarding them as mere illusions of the senses. From the indivisibility of being he inferred its incorporeality, and therefore denied all bodily existence.

The list of Eleatic philosophers is doubtfully closed by the name of Empedocles of Agrigentum, who in legend almost rivals Pythagoras. In the East he learned medicine and magic, the art of working miracles, of producing rain and wind. He decked himself in priestly garments, a golden girdle, and a crown, proclaiming himself to be a god. It is said by some that he never died, but ascended to the skies in the midst of a supernatural glory. By some it is related that he leaped into the crater of Etna, that, the manner of his death being unknown, he might still continue to pass for a god—an expectation disappointed by an eruption which cast out one of his brazen sandals.

Agreeably to the school to which he belonged, he relied on Reason and distrusted the Senses. From his fragments it has been inferred that he was sceptical of the guidance of the former as well as of the latter, founding his distrust on the imperfection the soul has contracted, and for which it has been condemned to existence in this world, and even to transmigration from body to body. Adopting the Eleatic doctrine that like can be only known by like, fire He mingles mysticism with philosophy. by fire, love by love, the recognition of the divine by man is sufficient proof that the Divine exists. His primary elements were four—Earth, Air, Fire, and Water; to these he added two principles, Love and Hate. The four elements he regarded as four gods, or divine eternal forces, since out of them all things are made. Love he regards as the creative power, the destroyer or modifier being Hate. It is obvious, therefore, that in him the strictly philosophical system of Xenophanes had degenerated into a mixed and mystical view, in which the physical, the metaphysical, and the moral were confounded together; and that, as the necessary consequence of such a state, the principles of knowledge were becoming unsettled, a suspicion arising that all philosophical systems were untrustworthy, and a general scepticism was already setting in.

To this result also, in no small degree, the labours of Democritus of Abdera tended. He had had the advantages derived from wealth in the procurement of knowledge, for it is said that his father was rich enough to be able to entertain the Persian King Xerxes, who was so gratified thereby that he left several Magi and ChaldÆans to complete the education of the youth. On his father's death, Democritus, dividing with his brothers the estate, took as his portion the share consisting of money, leaving to them the lands, that he might be better able to devote himself to travelling. He passed into Egypt, Ethiopia, Persia, and India, gathering knowledge from all those sources.

According to Democritus, "Nothing is true, or, if so, is not certain to us." Nevertheless, as, in his system sensation constitutes thought, and, at the same time, is but a change in the sentient being, "sensations are of necessity true;" from which somewhat obscure passage we may infer that, in the view of Democritus, though sensation is true subjectively, it is not true objectively. The sweet, the bitter, the hot, the cold, are simply creations of the mind; but in the outer object to which we append them, atoms and space alone exist, and our opinion of the properties of such objects is founded upon images emitted by them falling upon the senses. Confounding in this manner sensation with thought, and making them identical, he, moreover, included Reflexion as necessary for true knowledge, Sensation by itself being untrustworthy. Thus, though Sensation may indicate to us that sweet, bitter, hot, cold, occur in bodies, Reflexion teaches us that this is altogether an illusion, and that, in reality, atoms and space alone exist.

Devoting his attention, then, to the problem of perception—how the mind becomes aware of the existence of external things—he resorted to the hypothesis that they constantly throw off images of themselves, which are assimilated by the air through which they have to pass, and enter the soul by pores in its sensitive organs. Hence such images, being merely of the superficial form, are necessarily imperfect and untrue, and so, therefore, must be the knowledge yielded by them. Democritus rejected the one element of the Eleatics, affirming that there must He introduces the atomic theory. be many; but he did not receive the four of Empedocles, nor his principles of Love and Hate, nor the homoeomeriÆ of Anaxagoras. He also denied that the primary elements had any sensible qualities whatever. He conceived of all things as being composed of invisible, intangible, and indivisible particles or atoms, which, by reason of variation in their configuration, combination, or position, give rise to the varieties of forms: to the atom he imputed self-existence and eternal duration. His doctrine, therefore, explains how it is that the many can arise from the one, and in this particular he reconciled Destiny, Fate and resistless law. the apparent contradictions of the Ionians and Eleatics. The theory of chemistry, as it now exists, essentially includes his views. The general formative principle of Nature he regarded as being Destiny or Fate; but there are indications that by this he meant nothing more than irreversible law.

A system thus based upon severe mathematical considerations, and taking as its starting-point a vacuum and atoms—the former actionless and passionless; which considers the production of new things as only new aggregations, and the decay of the old as separations; which recognizes in compound bodies specific arrangements of atoms to one another; which can rise to the conception that even a single atom may constitute a world—such a system may commend itself to our attention for its results, but surely not to our approval, when we find it carrying us to the conclusions that even Is led to atheism. mathematical cognition is a mere semblance; that the soul is only a finely-constituted form fitted into the grosser bodily frame; that even for reason itself there is an absolute impossibility of all certainty; that scepticism is to be indulged in to that degree that we may doubt whether, when a cone has been cut asunder, its two surfaces are alike; that the final result of human inquiry is the absolute demonstration that man is incapable of knowledge; that, even if the truth be in his possession, he can never be certain of it; that the world is an illusive phantasm, and that there is no God.

I need scarcely refer to the legendary stories related of Democritus, as that he put out his eyes with a burning-glass that he might no longer be deluded with their false indications, and more tranquilly exercise his reason—a fiction bearing upon its face the contemptuous accusation of his antagonists, but, by the stolidity of subsequent ages, received as an actual fact instead of a sarcasm. As to his habit of so constantly deriding the knowledge and follies of men that he universally acquired the epithet of the laughing philosopher, we may receive the opinion of the great physician Hippocrates, who being requested by the people of Abdera to cure him of his madness, after long discoursing with him, expressed himself penetrated with admiration, and even with the most profound veneration for him, and rebuked those who had sent him with the remark that they themselves were the more distempered of the two.

Thus far European Greece had done but little in the cause of philosophy. The chief schools were in Asia Minor, or among the Greek colonies of Italy. But the time had now arrived when the mother country was to Rise of philosophy in European Greece. enter upon a distinguished career, though, it must be confessed, from a most unfavourable beginning. This was by no means the only occasion on which the intellectual activity of the Greek colonies made itself felt in the destinies of Europe. The mercantile character in a community has ever been found conducive to mental activity and physical adventure; it holds in light esteem prescriptive opinion, and puts things at the actual value they at the time possess. If the Greek colonies thus discharged the important function of introducing and disseminating speculative philosophy, we shall find them again, five hundred years later, occupied with a similar task on the advent of that period in which philosophical speculation was about to be supplanted by religious faith. For there Commercial communities favourable to new ideas. can be no doubt that, humanly speaking, the cause of the rapid propagation of Christianity, in its first ages, lay in the extraordinary facilities existing among the commercial communities scattered all around the shores of the Mediterranean Sea, from the ports of the Levant to those of France and Spain. An incessant intercourse was kept up among them during the five centuries before Christ; it became, under Roman influence, more and more active, and of increasing political importance. Such a state of things is in the highest degree conducive to the propagation of thought, and, indeed, to its origination, through the constant excitement it furnishes to intellectual activity. Commercial communities, in this respect, present a striking contrast to agricultural. By their aid speculative philosophy was rapidly disseminated everywhere, as was subsequently Christianity. But the agriculturists steadfastly adhered with marvellous stolidity to their ancestral traditions and polytheistic absurdities, until the very designation—paganism—under which their system passes was given as a nickname derived from themselves.

The intellectual condition of the Greek colonies of Italy and Sicily has not attracted the attention of critics in the manner it deserves. For, though its political result may appear to those whose attention is fixed by mere material aggrandizement to have been totally eclipsed by the subsequent power of the Roman republic, to one who looks at things in a mere general way it may be a probable inquiry whether the philosophy cultivated in those towns has not, in the course of ages, produced as solid and lasting results as the military achievements of the Eternal City. The relations of the Italian peninsula to the career of European civilization are to be classified under three epochs, the first corresponding to the philosophy generated in the southern Greek towns: this would have attained the elevation long before reached in the advanced systems of India had it not been prevented by the rapid development of Roman power; the second presents the military influence of republican and imperial Rome; to the third belongs the agency of ecclesiastical Rome—for the production of the last we shall find hereafter that the preceding two conspire. The Italian effect upon the whole has therefore been philosophical, material, and mixed. We are greatly in want of a history of the first, for which doubtless many facts still remain to a painstaking and enlightened inquirer.

It was on account of her small territory and her numerous population that Greece was obliged to colonize. To these motives must be added internal dissensions, and particularly the consequences of unequal marriages. So numerous did these colonies and their offshoots become, that a great Greek influence pervaded all the Mediterranean shores and many of the most important islands, attention more particularly being paid to the latter, from their supposed strategical value; thus, in the opinion of Alexander the Great, the command of the Mediterranean lay in the possession of Cyprus. The Greek colonists were filibusters; they seized by force the women wherever they settled, but their children were taught to speak the paternal language, as has been the case in more recent times with the descendants of the Spaniards in America. The wealth of some of these Greek colonial towns is said to have been incredible. Crotona was more than twelve miles in circumference; and Sybaris, another of the Italiot cities, was so luxurious and dissipated as even to give rise to a proverb. The prosperity of these places was due to two causes: they were not only the centres of great agricultural districts, but carried on also an active commerce in all directions, the dense population of the mother country offering them a steady and profitable market; they also maintained an active traffic with all the Mediterranean cities; thus, if they furnished Athens with corn, they also furnished Carthage with oil. In the Greek cities connected with this colonial system, especially in Athens, the business of ship-building and navigation was so extensively prosecuted as to give a special character to public life. In other parts of Greece, as in Sparta, it was altogether different. In that state the laws of Lycurgus had abolished private property; all things were held in common; savage life was reduced to a system, and therefore there was no object in commerce. But in Athens, commerce was regarded as being so far from dishonourable that some of the most illustrious men, whose names have descended to us as philosophers, were occupied with mercantile pursuits. Aristotle kept a druggist's shop in Athens, and Plato sold oil in Egypt.

It was the intention of Athens, had she succeeded in the conquest of Sicily, to make an attempt upon Carthage, foreseeing therein the dominion of the Mediterranean, as was actually realized subsequently by Rome. The destruction of that city constituted the point of ascendancy in the history of the Great Republic. Carthage stood upon a peninsula forty-five miles round, with a neck only three miles across. Her territory has been estimated as having a sea-line of not less than 1400 miles, and containing 300 towns; she had also possessions in Spain, in Sicily, and other Mediterranean islands, acquired, not by conquest, but by colonization. In the silver mines of Spain she employed not less than forty thousand men. In these respects she was guided by the maxims of her Phoenician ancestry, for the Tyrians had colonized for depÔts, and had forty stations of that kind in the Mediterranean. Indeed, Carthage herself originated in that way, owing her development to the position she held at the junction of the east and west basins. The Carthaginian merchants did not carry for hire, but dealt in their Carthaginian supremacy in the Mediterranean. commodities. This implied an extensive system of depÔts and bonding. They had anticipated many of the devices of modern commerce. They effected insurances, made loans on bottomry, and it has been supposed that their leathern money may have been of the nature of our bank notes.

In the preceding chapter we have spoken of the attempts of the Asiatics on Egypt and the south shore of the Mediterranean; we have now to turn to their operations on the north shore, the consequences of which are of the utmost interest in the history of philosophy. It appears that the cities of Asia Minor, after their contest with the Lydian kings, had fallen an easy prey to the Persian power. It remained, therefore, only for that power to pass to the European continent. A pretext is easily found where the policy is so clear. So far as the internal condition of Greece was concerned, nothing could be more tempting to an invader. There seemed to be no bond of union between the different towns, and, indeed, the more prominent ones Contest between them and the Greeks. might be regarded as in a state of chronic revolution. In Athens, since B.C. 622, the laws of Draco had been supplanted by those of Solon; and again and again the government had been seized by violence or gained through intrigue by one adventurer after another. Under these circumstances the Persian king passed an army into Europe. The military events of both this and the succeeding invasion under Xerxes have been more than sufficiently illustrated by the brilliant imagination of the lively Greeks. It was needless, however, to devise such fictions as the million of men who crossed into Europe, or the two hundred thousand who lay dead upon the field after the battle of PlatÆa. If there The fifty years' war, and eventual supremacy of Athens. were not such stubborn facts as the capture and burning of Athens, the circumstance that these wars lasted for fifty years would be sufficient to inform us that all the advantages were not on one side. Wars do not last so long without bringing upon both parties disasters as well as conferring glories; and had these been as exterminating and over whelming as classical authors have supposed, our surprise may well be excited that the Persian annals have preserved so little memory of them. Greece did not perceive that, if posterity must take her accounts as true, it must give the palm of glory to Persia, who could, with unfaltering perseverance, persist in attacks illustrated by such unparalleled catastrophes. She did not perceive that the annals of a nation may be more splendid from their exhibiting a courage which could bear up for half a century against continual disasters, and extract victory at last from defeat.

In pursuance of their policy, the Persians extended their dominion to Cyrene and Barca on the south, as well as to Thrace and Macedonia on the north. The Persian wars gave rise to that wonderful development in Greek art which has so worthily excited the admiration of subsequent ages. The assertion is quite true that after those wars the Greeks could form in sculpture living men. On the part of the Persians, these military undertakings were not of the base kind so common in antiquity; they were the carrying out of a policy conceived with great ability, their object being to obtain countries for tribute and not for devastation. The great critic Niebuhr, by whose opinions I am guided in the views I express of these events, admits that the Greek accounts, when examined, present little that was possible. The Persian empire does not seem to have suffered at all; and Plato, whose opinion must be considered as of very great authority, says that, on the whole, the Persian wars reflect extremely little honour on the Greeks. It was asserted that only thirty-one towns, and most of them small ones, were faithful to Greece. Treason to her seems for years in succession to have infected all her ablest men. It was not Pausanias alone who wanted to be king under the supremacy of Persia. Such a satrap would have borne about the same relation to the great king as the modern pacha does to the grand seignior. However, we must do justice to those able men. A king was what Greece in reality required; had she secured one at this time strong enough to hold her conflicting interests in check, she would have become the mistress of the world. Her leading men saw this.

The elevating effect of the Persian wars was chiefly felt in Athens. It was there that the grand development of pure art, literature, and science took place. As to Sparta, she remained barbarous as she had ever been; the Spartans continuing robbers and impostors, in their national life exhibiting not a single feature that can be commended. Mechanical art reached its perfection at Corinth; real art at Athens, finding a multitude not only of true, but also of new expressions. Before Pericles the only style of architecture was the Doric; his became at once the age of perfect Her progress in art. beauty. It also became the age of freedom in thinking and departure from the national faith. In this respect the history of Pericles and of Aspasia is very significant. His, also, was the great age of oratory, but of oratory leading to delusion, the democratical forms of Athens being altogether deceptive, power ever remaining in the hands of a few leading men, who did everything. The true popular sentiment, as was almost always the case under those ancient republican institutions, could find for itself no means of expression. The great men were only too prone to regard their fellow-citizens as a rabble, mere things to be played off against one another, and to consider that the objects of life are dominion and lust, that love, self-sacrifice, and devotion are fictions; that oaths are only good for deception.

Though the standard of statesmanship, at the period of the Persian wars, was very low, there can be no doubt that among the Greek leaders were those who clearly understood the causes of the Asiatic attack; and hence, with an instinct of self-preservation, defensive alliances were continually maintained with Egypt. When their valour and endurance had given to the Greeks a glorious issue to the war, the articles contained in the final treaty manifest clearly the motives and understandings of both parties. No Persian vessel was to appear between the Cyanean Rocks and Chelidonian Islands; no Persian army to approach within three days' journey of the Mediterranean Sea, B.C. 449.

To Athens herself the war had given political supremacy. We need only look at her condition fifty years after the battle of PlatÆa. She was mistress of more than a thousand miles of the coast of Asia Minor; she held as dependencies more than forty islands; she controlled the straits between Europe and Asia; her fleets ranged the Mediterranean and the Black Seas; she had monopolized the trade of all the adjoining countries; her magazines were full of the most valuable objects of commerce. From the ashes of the Persian fire she had risen up so supremely beautiful that her temples, her statues, her works of art, in She becomes the centre of policy and philosophy. their exquisite perfection, have since had no parallel in the world. Her intellectual supremacy equalled her political. To her, as to a focal point, the rays of light from every direction converged. The philosophers of Italy and Asia Minor directed their steps to her as to the acknowledged centre of mental activity. As to Egypt, an utter ruin had befallen her since she was desolated by the Persian arms. Yet we must not therefore infer that though, as conquerors, the Persians had trodden out the most aged civilization on the globe, as sovereigns they were haters of knowledge, or merciless as kings. We must not forget that the Greeks of Asia Minor were satisfied with their rule, or, at all events, preferred rather to remain their subjects than to contract any permanent political connexions with the conquering Greeks of Europe.

In this condition of political glory, Athens became not only the birthplace of new and beautiful productions of art, founded on a more just appreciation of the true than had yet been attained to in any previous age of the world (which, it may be added, have never been surpassed, if, indeed, they have been equalled since), she also became the receptacle for every philosophical opinion, new and old. Ionian, Italian, Egyptian, Persian, all were brought to her, and contrasted and compared together. Indeed, the philosophical celebrity of Greece is altogether due to Athens. The rest of the country participated but little in the cultivation of learning. It is a popular error that Greece, in the aggregate, was a learned country.

We have already seen how the researches of individual inquirers, passing from point to point, had conducted them, in many instances, to a suspicion of the futility of human knowledge; and looking at the results reached by the successive philosophical schools, we cannot fail to remark that there was a general tendency to scepticism. We have seen how, from the material and tangible beginnings of the Ionians, the Eleatics land us not only in a blank atheism, but in a disbelief of the existence of the world. And though it may be said that these were only the isolated results of special schools, it is not to be forgotten that they were of schools the most advanced. The time had now arrived when the name of a master was no more to usurp the place of reason, as had been hitherto the case; when these last results of the different methods of philosophizing were to be brought together, a criticism of a higher order established, and conclusions of a higher order deduced.

Thus it will ever be with all human investigation. The primitive philosophical elements from which we start are examined, first by one and then by another, each drawing his own special conclusions and deductions, and each firmly believing in the truth of his inferences. Each analyst has seen the whole subject from a particular point of view, without concerning himself with the discordances, contradictions, and incompatibilities obvious enough when his conclusions come to be compared with those of other analysts as skilful as himself. In process of time, it needs must be that a new school of examiners will arise, who, taking the results at which their predecessors have arrived from an examination of the primary elements, will institute a secondary comparison; a comparison of results with results; a comparison of a higher order, and more likely to lead to absolute truth.

Perhaps I cannot better convey what I here mean by this secondary and higher analysis of philosophical questions than by introducing, as an illustration, what took place subsequently in Rome, through her policy of universal religious toleration. The priests and followers of every god and of every faith were permitted to pursue without molestation their special forms of worship. Of these, it may be supposed that nearly all were perfectly sincere in their adherence to their special divinity, and, if the occasion had arisen, could have furnished unanswerable arguments in behalf of his supremacy and of the truth of his doctrines. Yet it is very clear that, by thus bringing these several primary systems into contact, a comparison of a secondary and of a higher order, and therefore far more likely to approach to absolute truth, must needs be established among them. It is very well known that the popular result of this secondary examination was the philosophical rejection of polytheism.

So, in Athens the result of the secondary examination of philosophical systems and deductions was scepticism as regards them all, and the rise of a new order of men—the Sophists—who not only rejected the validity of all former philosophical methods, but carried their infidelity to a degree plainly not warranted by the facts of the case, in this, that they not only denied that human reason had thus far succeeded in ascertaining anything, but even affirmed that it is incapable, from its very nature, as dependent on human organization, or the condition under which it acts, of determining the truth at all; nay, that even if the truth is actually in its possession, since it has no criterion by which to recognize it, it cannot so much as be certain that it is in such possession of it. From these principles it follows that, since we have no standard of the true, neither can we have any standard of the good, and that our ideas of what is good and what is evil are altogether produced by education or by convention. Or, to use the phrase adopted by the Sophists, "it is might that makes right." Right and wrong are hence seen to be mere fictions created by society, having no eternal or absolute existence in nature. The will of a monarch, or of a majority in a community, declares what the law shall be; the law defines what is right and what is wrong; and these, therefore, instead of having an actual existence, are mere illusions, owing their birth to the exercise of force. It is might that has determined and defined what is right. They reject philosophy, and even morality. And hence it follows that it is needless for a man to trouble himself with the monitions of conscience, or to be troubled thereby, for conscience, instead of being anything real, is an imaginary fiction, or, at the best, owes its origin to education, and is the creation of our social state. Hence the wise will give himself no concern as to a meritorious act or a crime, seeing that the one is intrinsically neither better nor worse than the other; but he will give himself sedulous concern as respects his outer or external relations—his position in society; conforming his acts to that standard which it in its wisdom or folly, but in the exercise of its might, has declared shall be regarded as right. Or, if his occasions be such as to make it for his interest to depart from the social rule, let him do it in secrecy; or, what is far better, let him cultivate rhetoric, that noble art by which the wrong may be made to appear the right; by which he who has committed a crime may so mystify society as to delude it into the belief that he is worthy of praise; and by which he may prove that his enemy, who has really performed some meritorious deed, has been guilty of a crime. Animated by such considerations, the Sophists passed from place to place, offering to sell for a sum of money a knowledge of the rhetorical art, and disposed of their services in the instruction of the youth of wealthy and noble families.

What shall we say of such a system and of such a state of things? Simply this: that it indicated a complete mental and social demoralization—mental demoralization, for the principles of knowledge were sapped, and man persuaded that his reason was no guide; social demoralization, for he was taught that right and wrong, virtue and vice, conscience, and law, and God, are imaginary fictions; that there is no harm in the commission of sin, though there may be harm, as assuredly there is folly, in being detected therein; that it is excellent for a man to sell his country to the Persian king, provided that the sum of money he receives is large enough, and that the transaction is so darkly conducted that the public, and particularly his enemies, can never find it out. Let him never forget that patriotism is the first delusion of a simpleton, and the last refuge of a knave.

Such were the results of the first attempt to correct the partial philosophies, by submitting them to the measure of a more universal one; such the manner in which, instead of only losing their exclusiveness and imperfections by their contact with one another, they were wrested from their proper object, and made subservient to the purpose of deception. Nor was it science alone that was affected; already might be discerned the foreshadowings of that They reject the national religion. conviction which many centuries later occasioned the final destruction of polytheism in Rome. Already, in Athens, the voice of philosophers was heard, that among so many gods and so many different worships it was impossible for a man to ascertain what is true. Already, many even of the educated were overwhelmed with the ominous suggestion that, if ever it had been the will of heaven to reveal any form of faith to the world, such a revelation, considering its origin, must necessarily have come with sufficient power to override all opposition; that if there existed only as many as two forms of faith synchronous and successful in the world, that fact would of itself demonstrate that neither of them is true, and that there never had been any revelation from an all-wise and omnipotent God. Nor was it merely among the speculative men that these infidelities were cherished; the leading politicians and statesmen had become deeply infected with them. It was not Anaxagoras alone who was convicted of atheism; the same charge was made against Pericles, the head of the republic—he who Spread of their opinions among the highest classes. had done so much for the glory of Athens—the man who, in practical life, was, beyond all question, the first of his age. With difficulty he succeeded, by the use of what influence remained to him, in saving the life of the guilty philosopher his friend, but in the public estimation he was universally viewed as a participator in his crime. If the foundations of philosophy and those of religion were thus sapped, the foundations of law experienced no better fate. The Sophists, who were wandering all over the world, saw that each nation had its own ideas of merit and demerit, and therefore its own system of law; that even in different towns there were contrary conceptions of right and wrong, and therefore opposing codes. It is evident that in such examinations they applied the same principles which had guided them in their analysis of philosophy and religion, and that the result could be no other than it was, to bring them to the conclusion that there is nothing absolute in justice or in law. To what an appalling condition society has arrived, when it reaches the positive conclusion that there is no truth, no religion, no justice, no virtue in the world; that the only object of human exertion is unrestrained physical enjoyment; the only standard of a man's position, wealth; that, since there is no possibility of truth, whose eternal principles might serve for an uncontrovertible and common guide, we should resort to deception and the arts of persuasion, that we may dupe others for our purposes; that there is no sin in undermining the social contract; no crime in blasphemy, or rather there is no blasphemy at all, since there are no gods; that "man is the measure of all things," as Protagoras teaches, and that "he is the criterion of existence;" that "thought is only the relation of the thinking subject to the object thought of, and that They end in blank atheism. the thinking subject, the soul, is nothing more than the sum of the different moments of thinking." It is no wonder that that Sophist who was the author of such doctrines should be condemned to death to satisfy the clamours of a populace who had not advanced sufficiently into the depths of this secondary, this higher philosophy, and that it was only by flight that he could save himself from the punishment awaiting the opening sentiment of his book: "Of the gods I cannot tell whether they are or not, for much hinders us from knowing this—both the obscurity of the subject and the shortness of life." It is no wonder that the social demoralization spread apace, when men like Gorgias, the disciple of Empedocles, were to be found, who laughed at virtue, made an open derision of morality, and proved, by metaphysical demonstration, that nothing at all exists.

From these statements respecting the crisis at which ancient philosophy had arrived, we might be disposed to believe that the result was unmitigated evil, for it scarcely deserves mention that the quibbles and disputes of the Sophists occasioned an extraordinary improvement of the Greek language, introducing precision into its terms, and a wonderful dialectical skill into its use. For us there may be extracted from these melancholy conclusions at least one instructive lesson—that it is not during the process of decomposition of philosophies, and especially of religions, Political dangers of the higher analysis. that social changes occur, for such breakings-up commonly go on in an isolated, and therefore innocuous way; but if by chance the fragments and decomposed portions are brought together, and attempts are made by fusion to incorporate them anew, or to extract from them, by a secondary analysis, what truth they contain, a crisis is at once brought on, and—such is the course of events—in the catastrophe that ensues Illustrations from the Middle Ages. they are commonly all absolutely destroyed. It was doubtless their foresight of such consequences that inspired the Italian statesmen of the Middle Ages with a resolute purpose of crushing in the bud every encroachment on ecclesiastical authority, and every attempt at individual interpretation of religious doctrines. For it is not to be supposed that men of clear intellect should be insensible to the obvious unreasonableness of many of the dogmas that had been consecrated by authority. But if once permission were accorded to human criticism and human interpretation, what other issue could there be than that doctrine upon doctrine, and sect upon sect should arise; that theological principles should undergo a total decomposition, until two men could scarcely be found whose views coincided; nay, even more than that, that the same man should change his opinion with the changing incidents of the different periods of his life. No matter what might be the plausible guise of the beginning, and the ostensibly cogent arguments for its necessity, once let the decomposition commence, and no human power could arrest it until it had become thorough and complete. Considering the prestige, the authority, and the mass of fact to be dealt with, it might take many centuries for this process to be finished, but that that result would at length be accomplished no enlightened man could doubt. The experience of the ancient European world had shown that in the act of such decompositions there is but little danger, since, for the time being, each sect, and, indeed, each individual, has a guiding rule of life. But as soon as the period of secondary analysis is reached a crisis must inevitably ensue, in all probability involving not only religion, but also the social contract. And though, by the exercise of force on the part of the interests that are disturbed, Danger of intellect outgrowing formulas of faith. aided by that popular sentiment which is abhorrent of anarchy, the crisis might, for a time, be put off, it could not be otherwise than that Europe should be left in that deplorable state which must result when the intellect of a people has outgrown its formulas of faith. A fearful condition to contemplate, for such a dislocation must also affect political relations, and necessarily implies revolt against existing law. Nations plunged in the abyss of irreligion must necessarily be nations in anarchy. For a time their tendency to explosion may be kept down by the firm application of the hand of power; but this is simply an antagonism, it is no cure. The social putrefaction proceeds, working its way downward into classes that are lower and lower, until at length it involves the institutions that are relied on for its arrest. Armies, the machinery of compression, once infected, the end is at hand, but no human Absolute necessity of preparing communities for these changes. foresight can predict what the event shall be, especially if the contemporaneous ruling powers have either ignorantly or wilfully neglected to prepare society for the inevitable trial it is about to undergo. It is the most solemn of all the duties of governments, when once they have become aware of such a momentous condition, to prepare the nations for its fearful consequences. For this it may, perhaps, be lawful for them to dissemble in a temporary manner, as it is sometimes proper for a physician to dissemble with his patient; it may be lawful for them even to resort to the use of force, but never should such measures of doubtful correctness be adopted without others directed to a preparation of the mass of society for the trials through which it is about to pass. Such, doubtless, were the profound views of the great Italian statesmen of the Middle Ages; such, doubtless, were the arguments by which they justified to themselves resistance against the beginning of the evil—a course for which Europe has too often and unfairly condemned them.

It remains for us now to review the details presented in the foregoing pages for the purpose of determining the successive phases of development through which the Greek mind passed. It is not with the truth or fallacy of these details that we have to do, but with their order of occurrence. They are points enabling us to describe graphically the curve of Grecian intellectual advance.

The starting point of Greek philosophy is physical and geocentral. The earth is the grand object of the universe, and, as the necessary result, erroneous ideas are entertained as to the relations and dimensions of the sea and air. This philosophy was hardly a century old before it began to cosmogonize, using the principles it considered itself sure of. Long before it was able to get rid of local ideas, such as upward and downward in space, it undertook to explain the origin of the world.

But, as advances were made, it was recognized that creation, in its various parts, displays intention and design, the adaptation of means to secure proposed ends. This suggested a reasoning and voluntary agency, like that of man, in the government of the world; and from a continual reference to human habits and acts, Greek philosophy passed through its stage of anthropoid conceptions.

A little farther progress awakened suspicions that the mind of man can obtain no certain knowledge; and the opinion at last prevailed that we have no trustworthy criterion of truth. In the scepticism thus setting in, the approach to Oriental ideas is each successive instant more and more distinct.

This period of doubt was the immediate forerunner of more correct cosmical opinions. The heliocentric mechanism of the planetary system was introduced, the earth deposed to a subordinate position. The doctrines, both physical and intellectual, founded on geocentric ideas, were necessarily endangered, and, since these had connected themselves with the prevailing religious views, and were represented by important material interests, the public began to practise persecution and the philosophers hypocrisy. Pantheistic notions of the nature of the world became more distinct, and, as their necessary consequence, the doctrines of Emanation, Transmigration, and Absorption were entertained. From this it is but a step to the suspicion that matter, motion, and time are phantasms of the imagination—opinions embodied in the atomic theory, which asserts that atoms and space alone exist; and which became more refined when it recognized that atoms are only mathematical points; and still more so when it considered them as mere centres of force. The brink of Buddhism was here approached.

As must necessarily ever be the case where men are coexisting in different psychical stages of advance, some having made a less, some a greater intellectual progress, all these views which we have described successively, were at last contemporaneously entertained. At this point commenced the action of the Sophists, who, by setting the doctrines of one school in opposition to those of another, and representing them all as of equal value, occasioned the destruction of them all, and the philosophy founded on physical speculation came to an end.

Of this phase of Greek intellectual life, if we compare the beginning with the close, we cannot fail to observe how great is the improvement. The thoughts dealt with at the later period are intrinsically of a higher order than those at the outset. From the puerilities and errors with which we have thus been occupied, we learn that there is a definite mode of progress for the mind of man; from the history of later times we shall find that it is ever in the same direction.
