But this Greek conception of divine immanence did not find favour with the Latin-speaking world. There a very different notion prevailed, the origin of which may be traced to the mental habits attending the primitive ancestor-worship. Out of materials furnished by the ghost-world a crude kind of monotheism could be reached by simply carrying back the thought to a single ghost-deity as the original ancestor of all the others. Some barbarous races have gone as far as this, as for example the Zulus, who have developed the doctrine of divine ancestors so far as to recognize a first ancestor, the Great Father, Unkulunkulu, who created the world.[12] The kind of theism reached by this process of thought differs essentially from the theism reached through the medium of nature-worship. For whereas in the latter case the god of the sky or the sea is regarded as a mysterious spirit acting in and through the phenomena, in the former case the phenomena are regarded as coerced into activity by some power existing outside of them, and this power is conceived as manlike in the crudest sense, having been originally thought of as the ghost of some man who once lived upon the earth. In the monotheism which is reached by thinking along these lines of inference, the universe is conceived as an inert lifeless machine, impelled by blind forces which have been set acting from without; and God is conceived as existing apart from the world in solitary inaccessible majesty,—"an absentee God," as Carlyle says, "sitting idle ever since the first Sabbath, at the outside of his universe, and 'seeing it go.'" This conception demands less of the intellect than the conception of God as immanent in the universe. It requires less grasp of mind and less width of experience, and it has accordingly been much the more common conception. The idea of the indwelling God is an attempt to reach out toward the reality, and as such it taxes the powers of the finite mind. The idea of God external to the universe is a symbol which in no wise approaches the reality, and for that very reason it does not tax the mental powers; there is an aspect of finality about it, in which the ordinary mind rests content and complains of whatever seeks to disturb its repose.

I must not be understood as ignoring the fact that this lower species of theism has been entertained by some of the loftiest minds of our race, both in ancient and in modern times. When once such an ever-present conception as the idea of God has become intertwined with the whole body of the thoughts of mankind, it is very difficult for the most powerful and subtle intelligence to change the form it has taken. It has become so far organized into the texture of the mind that it abides there unconsciously, like our fundamental axioms about number and magnitude; it sways our thought hither and thither without our knowing it. The two forms of theism here contrasted have slowly grown up under the myriad unassignable influences that in antiquity caused nature-worship to predominate among some people and ancestor-worship among others; they have coloured all the philosophizing that has been done for more than twenty centuries; and it is seldom that a thinker educated under the one form ever comes to adopt the other and habitually employ it, save under the mighty influence of modern science, the tendency of which, as we shall presently see, is all in one direction.

Among ancient thinkers the view of Deity as remote from the world prevailed with the followers of Epikuros, who held that the immortal gods could not be supposed to trouble themselves about the paltry affairs of men, but lived a blessed life of their own, undisturbed in the far-off empyrean. This left the world quite under the sway of blind forces, and thus we find it depicted in the marvellous poem of Lucretius, one of the loftiest monuments of Latin genius. It is to all appearance an atheistic world, albeit the author was perhaps more profoundly religious in spirit than any other Roman that ever lived, save Augustine; yet to his immediate scientific purpose this atheism was no drawback. When we are investigating natural phenomena, with intent to explain them scientifically, our proper task is simply to ascertain the physical conditions under which they occur, and the less we meddle with metaphysics or theology the better. As Laplace said, the mathematician, in solving his equations, does not need "the hypothesis of God."[13] To the scientific investigator, as such, the forces of nature are doubtless blind, like the x and y in algebra, but this is only so long as he contents himself with describing their modes of operation; when he undertakes to explain them philosophically, as we shall see, he can in no wise dispense with his theistic hypothesis. The Lucretian philosophy, therefore, admirable as a scientific coÖrdination of such facts about the physical universe as were then known, goes but very little way as a philosophy. It is interesting to note that this atheism followed directly from that species of theism which placed God outside of his universe. We shall find the case of modern atheism to be quite similar. As soon as this crude and misleading conception of God is refuted, as the whole progress of scientific knowledge tends to refute it, the modern atheist or positivist falls back upon his universe of blind forces and contents himself with it, while zealously shouting from the housetops that this is the whole story.

To one familiar with Christian ideas, the notion that Man is too insignificant a creature to be worth the notice of Deity seems at once pathetic and grotesque. In the view of Plato, by which all Christendom has been powerfully influenced, there is profound pathos. The wickedness and misery of the world wrought so strongly upon Plato's keen sympathies and delicate moral sense that he came to conclusions almost as gloomy as those of the Buddhist who regards existence as an evil. In the Timaios he depicts the material world as essentially vile; he is unable to think of the pure and holy Deity as manifested in it, and he accordingly separates the Creator from his creation by the whole breadth of infinitude. This view passed on to the Gnostics, for whom the puzzling problem of philosophy was how to explain the action of the spiritual God upon the material universe. Sometimes the interval was bridged by mediating Æons or emanations partly spiritual and partly material; sometimes the world was held to be the work of the devil, and in no sense divine.[14] The Greek fathers under the lead of Clement, espousing the higher theism, kept clear of this torrent of Gnostic thought; but upon Augustine it fell with full force, and he was carried away with it. In his earlier writings Augustine showed himself not incapable of comprehending the views of Clement and Athanasius; but his intense feeling of man's wickedness dragged him irresistibly in the opposite direction. In his doctrine of original sin, he represents humanity as cut off from all relationship with God, who is depicted as a crudely anthropomorphic Being far removed from the universe and accessible only through the mediating offices of an organized church. Compared with the thoughts of the Greek fathers this was a barbaric conception, but it was suited alike to the lower grade of culture in western Europe, and to the Latin political genius, which in the decline of the Empire was already occupying itself with its great and beneficent work of constructing an imperial Church. For these reasons the Augustinian theology prevailed, and in the Dark Ages which followed it became so deeply inwrought into the innermost fibres of Latin Christianity that it remains dominant to-day alike in Catholic and Protestant churches. With few exceptions every child born of Christian parents in western Europe or in America grows up with an idea of God the outlines of which were engraven upon men's minds by Augustine fifteen centuries ago. Nay, more, it is hardly too much to say that three fourths of the body of doctrine currently known as Christianity, unwarranted by Scripture and never dreamed of by Christ or his apostles, first took coherent shape in the writings of this mighty Roman, who was separated from the apostolic age by an interval of time like that which separates us from the invention of printing and the discovery of America. The idea of God upon which all this Augustinian doctrine is based is the idea of a Being actuated by human passions and purposes, localizable in space and utterly remote from that inert machine, the universe in which we live, and upon which He acts intermittently through the suspension of what are called natural laws. So deeply has this conception penetrated the thought of Christendom that we continually find it at the bottom of the speculations and arguments of men who would warmly repudiate it as thus stated in its naked outlines. It dominates the reasonings alike of believers and skeptics, of theists and atheists; it underlies at once the objections raised by orthodoxy against each new step in science and the assaults made by materialism upon every religious conception of the world; and thus it is chiefly responsible for that complicated misunderstanding which, by a lamentable confusion of thought, is commonly called "the conflict between religion and science."
