Not to my contemporaries, not to my compatriots—to mankind I commit my now completed work in the confidence that it will not be without value for them, even if this should be late recognised, as is commonly the lot of what is good. For it cannot have been for the passing generation, engrossed with the delusion of the moment, that my mind, almost against my will, has uninterruptedly stuck to its work through the course of a long life. And while the lapse of time has not been able to make me doubt the worth of my work, neither has the lack of sympathy; for I constantly saw the false and the bad, and finally the absurd and senseless,2 stand in universal admiration and honour, and I bethought myself that if it were not the case those who are capable of recognising the genuine and right are so rare that we may look for them in vain for some twenty years, then those who are capable of producing it could not be so few that their works afterwards form an exception to the perishableness of earthly things; and thus would be lost the reviving prospect of posterity which every one who sets before himself a high aim requires to strengthen him.

Whoever seriously takes up and pursues an object that does not lead to material advantages, must not count on [pg xviii] the sympathy of his contemporaries. For the most part he will see, however, that in the meantime the superficial aspect of that object becomes current in the world, and enjoys its day; and this is as it should be. The object itself must be pursued for its own sake, otherwise it cannot be attained; for any design or intention is always dangerous to insight. Accordingly, as the whole history of literature proves, everything of real value required a long time to gain acceptance, especially if it belonged to the class of instructive, not entertaining, works; and meanwhile the false flourished. For to combine the object with its superficial appearance is difficult, when it is not impossible. Indeed that is just the curse of this world of want and need, that everything must serve and slave for these; and therefore it is not so constituted that any noble and sublime effort, like the endeavour after light and truth, can prosper unhindered and exist for its own sake. But even if such an endeavour has once succeeded in asserting itself, and the conception of it has thus been introduced, material interests and personal aims will immediately take possession of it, in order to make it their tool or their mask. Accordingly, when Kant brought philosophy again into repute, it had soon to become the tool of political aims from above, and personal aims from below; although, strictly speaking, not philosophy itself, but its ghost, that passes for it. This should not really astonish us; for the incredibly large majority of men are by nature quite incapable of any but material aims, indeed they can conceive no others. Thus the pursuit of truth alone is far too lofty and eccentric an endeavour for us to expect all or many, or indeed even a few, faithfully to take part in. If yet we see, as for example at present in Germany, a [pg xix] remarkable activity, a general moving, writing, and talking with reference to philosophical subjects, we may confidently assume that, in spite of solemn looks and assurances, only real, not ideal aims, are the actual If Governments make philosophy a means of furthering political ends, learned men see in philosophical professorships a trade that nourishes the outer man just like any other; therefore they crowd after them in the assurance of their good intentions, that is, the purpose of subserving [pg xx] these ends. And they keep their word: not truth, not clearness, not Plato, not Aristotle, but the ends they were appointed to serve are their guiding star, and become at once the criterion of what is true, valuable, and to be respected, and of the opposites of these. Whatever, therefore, does not answer these ends, even if it were the most important and extraordinary things in their department, is either condemned, or, when this seems hazardous, suppressed by being unanimously ignored. Look only at their zeal against pantheism; will any simpleton believe that it proceeds from conviction? And, in general, how is it possible that philosophy, degraded to the position of a means of making one's bread, can fail to degenerate into sophistry? Just because this is infallibly the case, and the rule, “I sing the song of him whose bread I eat,” has always held good, the making of money by philosophy was regarded by the ancients as the characteristic of the sophists. But we have still to add this, that since throughout this world nothing is to be expected, can be demanded, or is to be had for gold but mediocrity, we must be contented with it here also. Consequently we see in all the German universities the cherished mediocrity striving to produce the philosophy which as yet is not there to produce, at its own expense and indeed in accordance with a predetermined standard and aim, a spectacle at which it would be almost cruel to mock.

While thus philosophy has long been obliged to serve entirely as a means to public ends on the one side and private ends on the other, I have pursued the course of my thought, undisturbed by them, for more than thirty years, and simply because I was obliged to do so and could not help myself, from an instinctive impulse, which [pg xxi] was, however, supported by the confidence that anything true one may have thought, and anything obscure one may have thrown light upon, will appeal to any thinking mind, no matter when it comprehends it, and will rejoice and comfort it. To such an one we speak as those who are like us have spoken to us, and have so become our comfort in the wilderness of this life. Meanwhile the object is pursued on its own account and for its own sake. Now it happens curiously enough with philosophical meditations, that precisely that which one has thought out and investigated for oneself, is afterwards of benefit to others; not that, however, which was originally intended for others. The former is confessedly nearest in character to perfect honesty; for a man does not seek to deceive himself, nor does he offer himself empty husks; so that all sophistication and all mere talk is omitted, and consequently every sentence that is written at once repays the trouble of reading it. Thus my writings bear the stamp of honesty and openness so distinctly on the face of them, that by this alone they are a glaring contrast to those of three celebrated sophists of the post-Kantian period. I am always to be found at the standpoint of reflection, i.e., rational deliberation and honest statement, never at that of inspiration, called intellectual intuition, or absolute thought; though, if it received its proper name, it would be called empty bombast and charlatanism. Working then in this spirit, and always seeing the false and bad in universal acceptance, yea, bombast3 and charlatanism4 in the highest honour, I have long renounced the approbation of my contemporaries. It is impossible that an age which for twenty years has applauded a Hegel, that intellectual Caliban, as the [pg xxii] greatest of the philosophers, so loudly that it echoes through the whole of Europe, could make him who has looked on at that desirous of its approbation. It has no more crowns of honour to bestow; its applause is prostituted, and its censure has no significance. That I mean what I say is attested by the fact that if I had in any way sought the approbation of my contemporaries, I would have had to strike out a score of passages which entirely contradict all their opinions, and indeed must in part be offensive to them. But I would count it a crime to sacrifice a single syllable to that approbation. My guiding star has, in all seriousness, been truth. Following it, I could first aspire only to my own approbation, entirely averted from an age deeply degraded as regards all higher intellectual efforts, and a national literature demoralised even to the exceptions, a literature in which the art of combining lofty words with paltry significance has reached its height. I can certainly never escape from the errors and weaknesses which, in my case as in every one else's, necessarily belong to my nature; but I will not increase them by unworthy accommodations.

As regards this second edition, first of all I am glad to say that after five and twenty years I find nothing to retract; so that my fundamental convictions have only been confirmed, as far as concerns myself at least. The alterations in the first volume therefore, which contains the whole text of the first edition, nowhere touch what is essential. Sometimes they concern things of merely secondary importance, and more often consist of very short explanatory additions inserted here and there. Only the criticism of the Kantian philosophy has received important corrections and large additions, for these could not be put into a supplementary book, such as [pg xxiii] those which are given in the second volume, and which correspond to each of the four books that contain the exposition of my own doctrine. In the case of the latter, I have chosen this form of enlarging and improving them, because the five and twenty years that have passed since they were composed have produced so marked a change in my method of exposition and in my style, that it would not have done to combine the content of the second volume with that of the first, as both must have suffered by the fusion. I therefore give both works separately, and in the earlier exposition, even in many places where I would now express myself quite differently, I have changed nothing, because I desired to guard against spoiling the work of my earlier years through the carping criticism of age. What in this regard might need correction will correct itself in the mind of the reader with the help of the second volume. Both volumes have, in the full sense of the word, a supplementary relation to each other, so far as this rests on the fact that one age of human life is, intellectually, the supplement of another. It will therefore be found, not only that each volume contains what the other lacks, but that the merits of the one consist peculiarly in that which is wanting in the other. Thus, if the first half of my work surpasses the second in what can only be supplied by the fire of youth and the energy of first conceptions, the second will surpass the first by the ripeness and complete elaboration of the thought which can only belong to the fruit of the labour of a long life. For when I had the strength originally to grasp the fundamental thought of my system, to follow it at once into its four branches, to return from them to the unity of their origin, and then to explain the whole distinctly, I could not yet be in a position to work out all [pg xxiv] the branches of the system with the fulness, thoroughness, and elaborateness which is only reached by the meditation of many years—meditation which is required to test and illustrate the system by innumerable facts, to support it by the most different kinds of proof, to throw light on it from all sides, and then to place the different points of view boldly in contrast, to separate thoroughly the multifarious materials, and present them in a well-arranged whole. Therefore, although it would, no doubt, have been more agreeable to the reader to have my whole work in one piece, instead of consisting, as it now does, of two halves, which must be combined in using them, he must reflect that this would have demanded that I should accomplish at one period of life what it is only possible to accomplish in two, for I would have had to possess the qualities at one period of life that nature has divided between two quite different ones. Hence the necessity of presenting my work in two halves supplementary to each other may be compared to the necessity in consequence of which a chromatic object-glass, which cannot be made out of one piece, is produced by joining together a convex lens of flint glass and a concave lens of crown glass, the combined effect of which is what was sought. Yet, on the other hand, the reader will find some compensation for the inconvenience of using two volumes at once, in the variety and the relief which is afforded by the handling of the same subject, by the same mind, in the same spirit, but in very different years. However, it is very advisable that those who are not yet acquainted with my philosophy should first of all read the first volume without using the supplementary books, and should make use of these only on a second perusal; otherwise it would be too difficult for them to grasp the [pg xxv] system in its connection. For it is only thus explained in the first volume, while the second is devoted to a more detailed investigation and a complete development of the individual doctrines. Even those who should not make up their minds to a second reading of the first volume had better not read the second volume till after the first, and then for itself, in the ordinary sequence of its chapters, which, at any rate, stand in some kind of connection, though a somewhat looser one, the gaps of which they will fully supply by the recollection of the first volume, if they have thoroughly comprehended it. Besides, they will find everywhere the reference to the corresponding passages of the first volume, the paragraphs of which I have numbered in the second edition for this purpose, though in the first edition they were only divided by lines.

I have already explained in the preface to the first edition, that my philosophy is founded on that of Kant, and therefore presupposes a thorough knowledge of it. I repeat this here. For Kant's teaching produces in the mind of every one who has comprehended it a fundamental change which is so great that it may be regarded as an intellectual new-birth. It alone is able really to remove the inborn realism which proceeds from the original character of the intellect, which neither Berkeley nor Malebranche succeed in doing, for they remain too much in the universal, while Kant goes into the particular, and indeed in a way that is quite unexampled both before and after him, and which has quite a peculiar, and, we might say, immediate effect upon the mind in consequence of which it undergoes a complete undeception, and forthwith looks at all things in another light. Only in this way can any one become susceptible to the [pg xxvi] more positive expositions which I have to give. On the other hand, he who has not mastered the Kantian philosophy, whatever else he may have studied, is, as it were, in a state of innocence; that is to say, he remains in the grasp of that natural and childish realism in which we are all born, and which fits us for everything possible, with the single exception of philosophy. Such a man then stands to the man who knows the Kantian philosophy as a minor to a man of full age. That this truth should nowadays sound paradoxical, which would not have been the case in the first thirty years after the appearance of the Critique of Reason, is due to the fact that a generation has grown up that does not know Kant properly, because it has never heard more of him than a hasty, impatient lecture, or an account at second-hand; and this again is due to the fact that in consequence of bad guidance, this generation has wasted its time with the philosophemes of vulgar, uncalled men, or even of bombastic sophists, which are unwarrantably commended to it. Hence the confusion of fundamental conceptions, and in general the unspeakable crudeness and awkwardness that appears from under the covering of affectation and pretentiousness in the philosophical attempts of the generation thus brought up. But whoever thinks he can learn Kant's philosophy from the exposition of others makes a terrible mistake. Nay, rather I must earnestly warn against such accounts, especially the more recent ones; and indeed in the years just past I have met with expositions of the Kantian philosophy in the writings of the Hegelians which actually reach the incredible. How should the minds that in the freshness of youth have been strained and ruined by the nonsense of Hegelism, be still capable of following Kant's profound [pg xxvii] investigations? They are early accustomed to take the hollowest jingle of words for philosophical thoughts, the most miserable sophisms for acuteness, and silly conceits for dialectic, and their minds are disorganised through the admission of mad combinations of words to which the mind torments and exhausts itself in vain to attach some thought. No Critique of Reason can avail them, no philosophy, they need a One word more for the professors of philosophy. I have always been compelled to admire not merely the sagacity, the true and fine tact with which, immediately on its appearance, they recognised my philosophy as something altogether different from and indeed dangerous to their own attempts, or, in popular language, something that would not suit their turn; but also the sure and astute policy by virtue of which they at once discovered the proper procedure with regard to it, the complete harmony with which they applied it, and the persistency with which they have remained faithful to it. This procedure, which further commended itself by the great ease of carrying it out, consists, as is well known, in altogether ignoring and thus in secreting—according to Goethe's malicious phrase, which just means the appropriating of what is of weight and significance. The efficiency of this quiet means is increased by the Corybantic shouts with which those who are at one reciprocally greet the birth of their own spiritual children—shouts which compel [pg xxix] the public to look and note the air of importance with which they congratulate themselves on the event. Who can mistake the object of such proceedings? Is there then nothing to oppose to the maxim, primum vivere, deinde philosophari? These gentlemen desire to live, and indeed to live by philosophy. To philosophy they are assigned with their wives and children, and in spite of Petrarch's povera e nuda vai filosofia, they have staked everything upon it. Now my philosophy is by no means so constituted that any one can live by it. It lacks the first indispensable requisite of a well-paid professional philosophy, a speculative theology, which—in spite of the troublesome Kant with his Critique of Reason—should and must, it is supposed, be the chief theme of all philosophy, even if it thus takes on itself the task of talking straight on of that of which it can know absolutely nothing. Indeed my philosophy does not permit to the professors the fiction they have so cunningly devised, and which has become so indispensable to them, of a reason that knows, perceives, or apprehends immediately and absolutely. This is a doctrine which it is only necessary to impose upon the reader at starting, in order to pass in the most comfortable manner in the world, as it were in a chariot and four, into that region beyond the possibility of all experience, which Kant has wholly and for ever shut out from our knowledge, and in which are found immediately revealed and most beautifully arranged the fundamental dogmas of modern, Judaising, optimistic Christianity. Now what in the world has my subtle philosophy, deficient as it is in these essential requisites, with no intentional aim, and unable to afford a means of subsistence, whose pole star is truth alone [pg xxx] the naked, unrewarded, unbefriended, often persecuted truth, and which steers straight for it without looking to the right hand or the left,—what, I say, has this to do with that alma mater, the good, well-to-do university philosophy which, burdened with a hundred aims and a thousand motives, comes on its course cautiously tacking, while it keeps before its eyes at all times the fear of the Lord, the will of the ministry, the laws of the established church, the wishes of the publisher, the attendance of the students, the goodwill of colleagues, the course of current politics, the momentary tendency of the public, and Heaven knows what besides? Or what has my quiet, earnest search for truth in common with the noisy scholastic disputations of the chair and the benches, the inmost motives of which are always personal aims. The two kinds of philosophy are, indeed, radically different. Thus it is that with me there is no compromise and no fellowship, that no one reaps any benefit from my works but the man who seeks the truth alone, and therefore none of the philosophical parties of the day; for they all follow their own aims, while I have only insight into truth to offer, which suits none of these aims, because it is not modelled after any of them. If my philosophy is to become susceptible of professorial exposition, the times must entirely change. What a pretty thing it would be if a philosophy by which nobody could live were to gain for itself light and air, not to speak of the general ear! This must be guarded against, and all must oppose it as one man. But it is not just such an easy game to controvert and refute; and, moreover, these are mistaken means to employ, because they just direct the attention of the public to the matter, and its taste for the lucubrations [pg xxxi] of the professors of philosophy might be destroyed by the perusal of my writings. For whoever has tasted of earnest will not relish jest, especially when it is tiresome. Therefore the silent system, so unanimously adopted, is the only right one, and I can only advise them to stick to it and go on with it as long as it will answer, that is, until to ignore is taken to imply ignorance; then there will just be time to turn back. Meanwhile it remains open to every one to pluck out a small feather here and there for his own use, for the superfluity of thoughts at home should not be very oppressive. Thus the ignoring and silent system may hold out a good while, at least the span of time I may have yet to live, whereby much is already won. And if, in the meantime, here and there an indiscreet voice has let itself be heard, it is soon drowned by the loud talking of the professors, who, with important airs, know how to entertain the public with very different things. I advise, however, that the unanimity of procedure should be somewhat more strictly observed, and especially that the young men should be looked after, for they are sometimes so fearfully indiscreet. For even so I cannot guarantee that the commended procedure will last for ever, and cannot answer for the final issue. It is a nice question as to the steering of the public, which, on the whole, is good and tractable. Although we nearly at all times see the Gorgiases and the Hippiases uppermost, although the absurd, as a rule, predominates, and it seems impossible that the voice of the individual can ever penetrate through the chorus of the befooling and the befooled, there yet remains to the genuine works of every age a quite peculiar, silent, slow, and powerful influence; and, [pg xxxii] as if by a miracle, we see them rise at last out of the turmoil like a balloon that floats up out of the thick atmosphere of this globe into purer regions, where, having once arrived, it remains at rest, and no one can draw it down again.
