Chapter XVII.(27) On Man's Need Of Metaphysics.

With the exception of man, no being wonders at its own existence; but it is to them all so much a matter of course that they do not observe it. The wisdom of nature speaks out of the peaceful glance of the brutes; for in them the will and the intellect are not yet so widely separated that they can be astonished at each other when they meet again. Thus here the whole phenomenon is still firmly attached to the stem of nature from which it has come, and is partaker of the unconscious omniscience of the great mother. Only after the inner being of nature (the will to live in its objectification) has ascended, vigorous and cheerful, through the two series of unconscious existences, and then through the long and broad series of animals, does it attain at last to reflection for the first time on the entrance of reason, thus in man. Then it marvels at its own works, and asks itself what it itself is. Its wonder however is the more serious, as it here stands for the first time consciously in the presence of _death_, and besides the finiteness of all existence, the vanity of all effort forces itself more or less upon it. With this reflection and this wonder there arises therefore for man alone, the _need for a metaphysic_; he is accordingly an _animal metaphysic.u.m_. At the beginning of his consciousness certainly he also accepts himself as a matter of course.

This does not last long however, but very early, with the first dawn of reflection, that wonder already appears, which is some day to become the mother of metaphysics. In agreement with this Aristotle also says at the beginning of his metaphysics: "??a ?a? t? ?a?a?e?? ?? a????p?? ?a? ???

?a? t? p??t?? ???a?t? f???s?fe??." (_Propter admirationem enim et nunc et primo inceperunt homines philosophari._) Moreover, the special philosophical disposition consists primarily in this, that a man is capable of wonder beyond the ordinary and everyday degree, and is thus induced to make the _universal_ of the phenomenon his problem, while the investigators in the natural sciences wonder only at exquisite or rare phenomena, and their problem is merely to refer these to phenomena which are better known. The lower a man stands in an intellectual regard the less of a problem is existence itself for him; everything, how it is, and that it is, appears to him rather a matter of course. This rests upon the fact that his intellect still remains perfectly true to its original destiny of being serviceable to the will as the medium of motives, and therefore is closely bound up with the world and nature, as an integral part of them. Consequently it is very far from comprehending the world in a purely objective manner, freeing itself, so to speak, from the whole of things, opposing itself to this whole, and so for a while becoming as if self-existent. On the other hand, the philosophical wonder which springs from this is conditioned in the individual by higher development of the intellect, yet in general not by this alone; but without doubt it is the knowledge of death, and along with this the consideration of the suffering and misery of life, which gives the strongest impulse to philosophical reflection and metaphysical explanation of the world. If our life were endless and painless, it would perhaps occur to no one to ask why the world exists, and is just the kind of world it is; but everything would just be taken as a matter of course. In accordance with this we find that the interest which philosophical and also religious systems inspire has always its strongest hold in the dogma of some kind of existence after death; and although the most recent systems seem to make the existence of their G.o.ds the main point, and to defend this most zealously, yet in reality this is only because they have connected their special dogma of immortality with this, and regard the one as inseparable from the other: only on this account is it of importance to them. For if one could establish their doctrine of immortality for them in some other way, their lively zeal for their G.o.ds would at once cool, and it would give place almost to complete indifference if, conversely, the absolute impossibility of immortality were proved to them; for the interest in the existence of the G.o.ds would vanish with the hope of a closer acquaintance with them, to the residuum which might connect itself with their possible influence on the events of this present life. But if one could prove that continued existence after death is incompatible with the existence of G.o.ds, because, let us say, it pre-supposes originality of being, they would soon sacrifice the G.o.ds to their own immortality and become zealous for Atheism. The fact that the materialistic systems, properly so-called, and also absolute scepticism, have never been able to obtain a general or lasting influence, depends upon the same grounds.

Temples and churches, paG.o.das and mosques, in all lands and in all ages, in splendour and vastness, testify to the metaphysical need of man, which, strong and ineradicable, follows close upon his physical need. Certainly whoever is satirically inclined might add that this metaphysical need is a modest fellow who is content with poor fare. It sometimes allows itself to be satisfied with clumsy fables and insipid tales. If only imprinted early enough, they are for a man adequate explanations of his existence and supports of his morality. Consider, for example, the Koran. This wretched book was sufficient to found a religion of the world, to satisfy the metaphysical need of innumerable millions of men for twelve hundred years, to become the foundation of their morality, and of no small contempt for death, and also to inspire them to b.l.o.o.d.y wars and most extended conquests. We find in it the saddest and the poorest form of Theism. Much may be lost through the translations; but I have not been able to discover one single valuable thought in it. Such things show that metaphysical capacity does not go hand in hand with the metaphysical need. Yet it will appear that in the early ages of the present surface of the earth this was not the case, and that those who stood considerably nearer than we do to the beginning of the human race and the source of organic nature, had also both greater energy of the intuitive faculty of knowledge, and a truer disposition of mind, so that they were capable of a purer, more direct comprehension of the inner being of nature, and were thus in a position to satisfy the metaphysical need in a more worthy manner. Thus originated in the primitive ancestors of the Brahmans, the Rishis, the almost super-human conceptions which were afterwards set down in the Upanishads of the Vedas.

On the other hand, there have never been wanting persons who were interested in deriving their living from that metaphysical need, and in making the utmost they could out of it. Therefore among all nations there are monopolists and farmers-general of it-the priests. Yet their trade had everywhere to be a.s.sured to them in this way, that they received the right to impart their metaphysical dogmas to men at a very early age, before the judgment has awakened from its morning slumber, thus in early childhood; for then every well-impressed dogma, however senseless it may be, remains for ever. If they had to wait till the judgment is ripe, their privileges could not continue.

A second, though not a numerous cla.s.s of persons, who derive their support from the metaphysical need of man, is const.i.tuted by those who live by _philosophy_. By the Greeks they were called Sophists, by the moderns they are called Professors of Philosophy. Aristotle (_Metaph._, ii. 2) without hesitation numbers Aristippus among the Sophists. In Diogenes Laertius (ii. 65) we find that the reason of this is that he was the first of the Socratics who accepted payment for his philosophy; on account of which Socrates also returned him his present. Among the moderns also those who live _by_ philosophy are not only, as a rule, and with the rarest exceptions, quite different from those who live _for_ philosophy, but they are very often the opponents, the secret and irreconcilable enemies of the latter. For every true and important philosophical achievement will overshadow their own too much, and, moreover, cannot adapt itself to the views and limitations of their guild. Therefore it is always their endeavour to prevent such a work from making its way; and for this purpose, according to the age and circ.u.mstances in each case, the customary means are suppressing, concealing, hushing up, ignoring and keeping secret, or denying, disparaging, censuring, slandering and distorting, or, finally, denouncing and persecuting. Hence many a great man has had to drag himself wearily through life unknown, unhonoured, unrewarded, till at last, after his death, the world became undeceived as to him and as to them. In the meanwhile they had attained their end, had been accepted by preventing him from being accepted, and, with wife and child, had lived _by_ philosophy, while he lived _for_ it. But if he is dead, then the thing is reversed; the new generation of the former cla.s.s, which always exists, now becomes heir to his achievements, cuts them down to its own measure, and now lives _by_ him. That Kant could yet live both _by_ and _for_ philosophy depended on the rare circ.u.mstance that, for the first time since _Divus Antoninus_ and _Divus Julia.n.u.s_, a philosopher sat on the throne. Only under such auspices could the "Critique of Pure Reason" have seen the light. Scarcely was the king dead than we see that Kant also, seized with fear, because he belonged to the guild, modified, expurgated, and spoiled his masterpiece in the second edition, and yet was soon in danger of losing his place; so that Campe invited him to come to him, in Brunswick, and live with him as the instructor of his family (Ring., _Ansichten aus Kant's Leben_, p. 68). University philosophy is, as a rule, mere juggling. Its real aim is to impart to the students, in the deepest ground of their thought, that tendency of mind which the ministry that appoints to the professorships regards as consistent with its views.

The ministry may also be perfectly right in this from a statesman's point of view; only the result of it is that such philosophy of the chair is a _nervis alienis mobile lignum_, and cannot be regarded as serious philosophy, but as the mere jest of it. Moreover, it is at any rate just that such inspection or guidance should extend only to the philosophy of the chair, and not to the real philosophy that is in earnest. For if anything in the world is worth wishing for-so well worth wishing for that even the ignorant and dull herd in its more reflective moments would prize it more than silver and gold-it is that a ray of light should fall on the obscurity of our being, and that we should gain some explanation of our mysterious existence, in which nothing is clear but its misery and its vanity. But even if this is in itself attainable, it is made impossible by imposed and compulsory solutions.

We shall now subject to a general consideration the different ways of satisfying this strong metaphysical need.

By _metaphysics_ I understand all knowledge that pretends to transcend the possibility of experience, thus to transcend nature or the given phenomenal appearance of things, in order to give an explanation of that by which, in some sense or other, this experience or nature is conditioned; or, to speak in popular language, of that which is behind nature, and makes it possible. But the great original diversity in the power of understanding, besides the cultivation of it, which demands much leisure, makes so great a difference between men, that as soon as a people has emerged from the state of savages, no _one_ metaphysic can serve for them all. Therefore among civilised nations we find throughout two different kinds of metaphysics, which are distinguished by the fact that the one has its evidence _in itself_, the other _outside itself_. Since the metaphysical systems of the first kind require reflection, culture, and leisure for the recognition of their evidence, they can be accessible only to a very small number of men; and, moreover, they can only arise and maintain their existence in the case of advanced civilisation. On the other hand, the systems of the second kind exclusively are for the great majority of men who are not capable of thinking, but only of believing, and who are not accessible to reasons, but only to authority. These systems may therefore be called metaphysics of the people, after the a.n.a.logy of poetry of the people, and also wisdom of the people, by which is understood proverbs. These systems, however, are known under the name of religions, and are found among all nations, not excepting even the most savage. Their evidence is, as has been said, external, and as such is called revelation, which is authenticated by signs and miracles. Their arguments are princ.i.p.ally threats of eternal, and indeed also temporal evils, directed against unbelievers, and even against mere doubters. As _ultima ratio theologorum_, we find among many nations the stake or things similar to it. If they seek a different authentication, or if they make use of other arguments, they already make the transition into the systems of the first kind, and may degenerate into a mixture of the two, which brings more danger than advantage, for their invaluable prerogative of being imparted to _children_ gives them the surest guarantee of the permanent possession of the mind, for thereby their dogmas grow into a kind of second inborn intellect, like the twig upon the grafted tree; while, on the other hand, the systems of the first kind only appeal to grown-up people, and in them always find a system of the second kind already in possession of their convictions. Both kinds of metaphysics, whose difference may be briefly expressed by the words reasoned conviction and faith, have this in common, that every one of their particular systems stands in a hostile relation to all the others of its kind. Between those of the first kind war is waged only with word and pen; between those of the second with fire and sword as well. Several of the latter owe their propagation in part to this last kind of polemic, and all have by degrees divided the earth between them, and indeed with such decided authority that the peoples of the earth are distinguished and separated more according to them than according to nationality or government. They alone _reign_, each in its own province. The systems of the first kind, on the contrary, are at the most _tolerated_, and even this only because, on account of the small number of their adherents, they are for the most part not considered worth the trouble of combating with fire and sword-although, where it seemed necessary, these also have been employed against them with effect; besides, they occur only in a sporadic form. Yet in general they have only been endured in a tamed and subjugated condition, for the system of the second kind which prevailed in the country ordered them to conform their teaching more or less closely to its own. Sometimes it not only subjugated them, but even employed their services and used them as a support, which is however a dangerous experiment. For these systems of the first kind, since they are deprived of power, believe they may advance themselves by craft, and never entirely lay aside a secret ill-will which at times comes unexpectedly into prominence and inflicts injuries which are hard to heal. For they are further made the more dangerous by the fact that all the real sciences, not even excepting the most innocent, are their secret allies against the systems of the second kind, and without themselves being openly at war with the latter, suddenly and unexpectedly do great mischief in their province. Besides, the attempt which is aimed at by the enlistment referred to of the services of the systems of the first kind by the second-the attempt to add an inner authentication to a system whose original authentication was external, is in its nature perilous; for, if it were capable of such an authentication, it would never have required an external one. And in general it is always a hazardous thing to attempt to place a new foundation under a finished structure. Moreover, how should a religion require the suffrage of a philosophy? It has everything upon its side-revelation, tradition, miracles, prophecies, the protection of the government, the highest rank, as is due to the truth, the consent and reverence of all, a thousand temples in which it is proclaimed and practised, bands of sworn priests, and, what is more than all, the invaluable privilege of being allowed to imprint its doctrines on the mind at the tender age of childhood, whereby they became almost like innate ideas. With such wealth of means at its disposal, still to desire the a.s.sent of poor philosophers it must be more covetous, or to care about their contradiction it must be more fearful, than seems to be compatible with a good conscience.

To the distinction established above between metaphysics of the first and of the second kind, we have yet to add the following:-A system of the first kind, thus a philosophy, makes the claim, and has therefore the obligation, in everything that it says, _sensu stricto et proprio_, to be true, for it appeals to thought and conviction. A religion, on the other hand, being intended for the innumerable mult.i.tude who, since they are incapable of examination and thought, would never comprehend the profoundest and most difficult truths _sensu proprio_, has only the obligation to be true _sensu allegorico_. Truth cannot appear naked before the people. A symptom of this _allegorical_ nature of religions is the _mysteries_ which are to be found perhaps in them all, certain dogmas which cannot even be distinctly thought, not to speak of being literally true. Indeed, perhaps it might be a.s.serted that some absolute contradictions, some actual absurdities, are an essential ingredient in a complete religion, for these are just the stamp of its allegorical nature, and the only adequate means of making the ordinary mind and the uncultured understanding _feel_ what would be incomprehensible to it, that religion has ultimately to do with quite a different order of things, with an order of _things in themselves_, in the presence of which the laws of this phenomenal world, in conformity with which it must speak, vanish; and that therefore not only the contradictory but also the comprehensible dogmas are really only allegories and accommodations to the human power of comprehension. It seems to me that it was in this spirit that Augustine and even Luther adhered to the mysteries of Christianity in opposition to Pelagianism, which sought to reduce everything to the dull level of comprehensibility. From this point of view it is also conceivable how Tertullian could say in all seriousness: "_Prorsus credibile est, quia ineptum est: ... certum est, quia impossibile_" (_De Carne Christi_, c.

5). This _allegorical_ nature of religions makes them independent of the proofs which are inc.u.mbent on philosophy, and in general withdraws them from investigation. Instead of this they require faith, that is, a voluntary admission that such is the state of the case. Since, then, faith guides action, and the allegory is always so framed that, as regards the practical, it leads precisely to that which the truth _sensu proprio_ would also lead to, religion is justified in promising to those who believe eternal salvation. Thus we see that in the main, and for the great majority, who cannot apply themselves to thought, religions very well supply the place of metaphysics in general, the need of which man feels to be imperative. They do this partly in a practical interest, as the guiding star of their action, the unfurled standard of integrity and virtue, as Kant admirably expresses it; partly as the indispensable comfort in the heavy sorrows of life, in which capacity they fully supply the place of an objectively true metaphysic, because they lift man above himself and his existence in time, as well perhaps as such a metaphysic ever could. In this their great value and indeed necessity shows itself very clearly. For Plato says, and says rightly, "f???s?f?? p????? ?d??at?? e??a?" (_vulgus philosophum esse impossible est_. _De Rep._, vi. p. 89, _Bip_.) On the other hand, the only stumbling-stone is this, that religions never dare to confess their allegorical nature, but have to a.s.sert that they are true _sensu proprio_. They thereby encroach on the province of metaphysics proper, and call forth the antagonism of the latter, which has therefore expressed itself at all times when it was not chained up. The controversy which is so perseveringly carried on in our own day between supernaturalists and rationalists also rests on the failure to recognise the allegorical nature of all religion. Both wish to have Christianity true _sensu proprio_; in this sense the former wish to maintain it without deduction, as it were with skin and hair; and thus they have a hard stand to make against the knowledge and general culture of the age. The latter wish to explain away all that is properly Christian; whereupon they retain something which is neither _sensu proprio_ nor _sensu allegorico_ true, but rather a mere plat.i.tude, little better than Judaism, or at the most a shallow Pelagianism, and, what is worst, an abject optimism, absolutely foreign to Christianity proper. Moreover, the attempt to found a religion upon reason removes it into the other cla.s.s of metaphysics, that which has its authentication _in itself_, thus to the foreign ground of the philosophical systems, and into the conflict which these wage against each other in their own arena, and consequently exposes it to the light fire of scepticism and the heavy artillery of the "Critique of Pure Reason;" but for it to venture there would be clear presumption.

It would be most beneficial to both kinds of metaphysics that each of them should remain clearly separated from the other and confine itself to its own province, that it may there be able to develop its nature fully.

Instead of which, through the whole Christian era, the endeavour has been to bring about a fusion of the two, for the dogmas and conceptions of the one have been carried over into the other, whereby both are spoiled. This has taken place in the most open manner in our own day in that strange hermaphrodite or centaur, the so-called philosophy of religion, which, as a kind of gnosis, endeavours to interpret the given religion, and to explain what is true _sensu allegorico_ through something which is true _sensu proprio_. But for this we would have to know and possess the truth _sensu proprio_ already; and in that case such an interpretation would be superfluous. For to seek first to find metaphysics, _i.e._, the truth _sensu proprio_, merely out of religion by explanation and interpretation would be a doubtful and dangerous undertaking, to which one would only make up one's mind if it were proved that truth, like iron and other base metals, could only be found in a mixed, not in a pure form, and therefore one could only obtain it by reduction from the mixed ore.

Religions are necessary for the people, and an inestimable benefit to them. But if they oppose themselves to the progress of mankind in the knowledge of the truth, they must with the utmost possible forbearance be set aside. And to require that a great mind-a Shakspeare; a Goethe-should make the dogmas of any religion implicitly, _bona fide et sensu proprio_, his conviction is to require that a giant should put on the shoe of a dwarf.

Religions, being calculated with reference to the power of comprehension of the great ma.s.s of men, can only have indirect, not immediate truth. To require of them the latter is as if one wished to read the letters set up in the form-chase, instead of their impression. The value of a religion will accordingly depend upon the greater or less content of truth which it contains under the veil of allegory, and then upon the greater or less distinctness with which it becomes visible through this veil, thus upon the transparency of the latter. It almost seems that, as the oldest languages are the most perfect, so also are the oldest religions. If I were to take the results of my philosophy as the standard of truth, I would be obliged to concede to Buddhism the pre-eminence over the rest. In any case it must be a satisfaction to me to see my teaching in such close agreement with a religion which the majority of men upon the earth hold as their own; for it numbers far more adherents than any other. This agreement, however, must be the more satisfactory to me because in my philosophising I have certainly not been under its influence. For up till 1818, when my work appeared, there were very few, exceedingly incomplete and scanty, accounts of Buddhism to be found in Europe, which were almost entirely limited to a few essays in the earlier volumes of "Asiatic Researches," and were princ.i.p.ally concerned with the Buddhism of the Burmese. Only since then has fuller information about this religion gradually reached us, chiefly through the profound and instructive essays of the meritorious member of the St. Petersburg Academy, J. J. Schmidt, in the proceedings of his Academy, and then little by little through several English and French scholars, so that I was able to give a fairly numerous list of the best works on this religion in my work, "_Ueber den Willen in der Natur_," under the heading _Sinologie_. Unfortunately Csoma Korosi, that persevering Hungarian, who, in order to study the language and sacred writings of Buddhism, spent many years in Tibet, and for the most part in Buddhist monasteries, was carried off by death just as he was beginning to work out for us the results of his researches. I cannot, however, deny the pleasure with which I read, in his provisional accounts, several pa.s.sages cited directly from the Kahgyur itself; for example, the following conversation of the dying Buddha with Brahma, who is doing him homage: "There is a description of their conversation on the subject of creation,-by whom was the world made? Shakya asks several questions of Brahma,-whether was it he who made or produced such and such things, and endowed or blessed them with such and such virtues or properties,-whether was it he who caused the several revolutions in the destruction and regeneration of the world. He denies that he had ever done anything to that effect. At last he himself asks Shakya how the world was made,-by whom? Here are attributed all changes in the world to the moral works of the animal beings, and it is stated that in the world all is illusion, there is no reality in the things; all is empty. Brahma, being instructed in his doctrine, becomes his follower" (Asiatic Researches, vol. XX. p.

434).

I cannot place, as is always done, the fundamental difference of all religions in the question whether they are monotheistic, polytheistic, pantheistic, or atheistic, but only in the question whether they are optimistic or pessimistic, that is, whether they present the existence of the world as justified by itself, and therefore praise and value it, or regard it as something that can only be conceived as the consequence of our guilt, and therefore properly ought not to be, because they recognise that pain and death cannot lie in the eternal, original, and immutable order of things, in that which in every respect ought to be. The power by virtue of which Christianity was able to overcome first Judaism, and then the heathenism of Greece and Rome, lies solely in its pessimism, in the confession that our state is both exceedingly wretched and sinful, while Judaism and heathenism were optimistic. That truth, profoundly and painfully felt by all, penetrated, and bore in its train the need of redemption.

I turn to a general consideration of the other kind of metaphysics, that which has its authentication in itself, and is called _philosophy_. I remind the reader of its origin, mentioned above, in a _wonder_ concerning the world and our own existence, inasmuch as these press upon the intellect as a riddle, the solution of which therefore occupies mankind without intermission. Here, then, I wish first of all to draw attention to the fact that this could not be the case if, in Spinoza's sense, which in our own day has so often been brought forward again under modern forms and expositions as pantheism, the world were an "_absolute substance_," and therefore an _absolutely necessary existence_. For this means that it exists with so great a necessity that beside it every other necessity comprehensible to our understanding as such must appear as an accident. It would then be something which comprehended in itself not only all actual but also all possible existence, so that, as Spinoza indeed declares, its possibility and its actuality would be absolutely one. Its non-being would therefore be impossibility itself; thus it would be something the non-being or other-being of which must be completely inconceivable, and which could therefore just as little be thought away as, for example, s.p.a.ce or time. And since, further, _we ourselves_ would be parts, modes, attributes, or accidents of such an absolute substance, which would be the only thing that, in any sense, could ever or anywhere exist, our and its existence, together with its properties, would necessarily be very far from presenting itself to us as remarkable, problematical, and indeed as an unfathomable and ever-disquieting riddle, but, on the contrary, would be far more self-evident than that two and two make four. For we would necessarily be incapable of thinking anything else than that the world is, and is, as it is; and therefore we would necessarily be as little conscious of its existence _as such_, _i.e._, as a problem for reflection, as we are of the incredibly fast motion of our planet.

All this, however, is absolutely not the case. Only to the brutes, who are without thought, does the world and existence appear as a matter of course; to man, on the contrary, it is a problem, of which even the most uneducated and narrow-minded becomes vividly conscious in certain brighter moments, but which enters more distinctly and more permanently into the consciousness of each one of us the clearer and more enlightened that consciousness is, and the more material for thought it has acquired through culture, which all ultimately rises, in minds that are naturally adapted for philosophising, to Plato's "?a?a?e??, a?a f???s?f???? pa???"

(_mirari, valde philosophicus affectus_), that is, to that _wonder_ which comprehends in its whole magnitude that problem which unceasingly occupies the n.o.bler portion of mankind in every age and in every land, and gives it no rest. In fact, the pendulum which keeps in motion the clock of metaphysics, that never runs down, is the consciousness that the non-existence of this world is just as possible as its existence. Thus, then, the Spinozistic view of it as an absolutely necessary existence, that is, as something that absolutely and in every sense ought to and must be, is a false one. Even simple Theism, since in its cosmological proof it tacitly starts by inferring the previous non-existence of the world from its existence, thereby a.s.sumes beforehand that the world is something contingent. Nay, what is more, we very soon apprehend the world as something the non-existence of which is not only conceivable, but indeed preferable to its existence. Therefore our wonder at it easily pa.s.ses into a brooding over the _fatality_ which could yet call forth its existence, and by virtue of which such stupendous power as is demanded for the production and maintenance of such a world could be directed so much against its own interest. The philosophical astonishment is therefore at bottom perplexed and melancholy; philosophy, like the overture to "Don Juan," commences with a minor chord. It follows from this that it can neither be Spinozism nor optimism. The more special nature, which has just been indicated, of the astonishment which leads us to philosophise clearly springs from the sight of the _suffering and the wickedness_ in the world, which, even if they were in the most just proportion to each other, and also were far outweighed by good, are yet something which absolutely and in general ought not to be. But since now nothing can come out of nothing, these also must have their germ in the origin or in the kernel of the world itself. It is hard for us to a.s.sume this if we look at the magnitude, the order and completeness, of the physical world, for it seems to us that what had the power to produce such a world must have been able to avoid the suffering and the wickedness. That a.s.sumption (the truest expression of which is Ormuzd and Ahrimines), it is easy to conceive, is hardest of all for Theism. Therefore the freedom of the will was primarily invented to account for wickedness. But this is only a concealed way of making something out of nothing, for it a.s.sumes an _Operari_ that proceeded from no _Esse_ (see Die beiden _Grundprobleme der Ethik_, p. 58, _et seq._; second edition, p. 57 _et seq._.) Then it was sought to get rid of evil by attributing it to matter, or to unavoidable necessity, whereby the devil, who is really the right _Expediens ad hoc_, was unwillingly set aside. To evil also belongs _death_; but wickedness is only the throwing of the existing evil from oneself on to another. Thus, as was said above, it is wickedness, evil, and death that qualify and intensify the philosophical astonishment. Not merely that the world exists, but still more that it is such a wretched world, is the _punctum pruriens_ of metaphysics, the problem which awakens in mankind an unrest that cannot be quieted by scepticism nor yet by criticism.

We find _physics_ also (in the widest sense of the word) occupied with the explanation of the phenomena in the world. But it lies in the very nature of its explanations themselves that they cannot be sufficient. Physics cannot stand on its own feet, but requires a metaphysic to lean upon, whatever airs it may give itself towards the latter. For it explains the phenomena by something still more unknown than they are themselves; by laws of nature, resting upon forces of nature, to which the power of life also belongs. Certainly the whole present condition of all things in the world, or in nature, must necessarily be explicable from purely physical causes. But such an explanation-supposing one actually succeeded so far as to be able to give it-must always just as necessarily be tainted with two imperfections (as it were with two sores, or like Achilles with the vulnerable heel, or the devil with the horse's hoof), on account of which everything so explained really remains still unexplained. First with this imperfection, that the _beginning_ of every explanatory chain of causes and effects, _i.e._, of connected changes, can absolutely _never_ be reached, but, just like the limits of the world in s.p.a.ce and time, unceasingly recedes _in infinito_. Secondly with this, that the whole of the efficient causes out of which everything is explained constantly rest upon something which is completely inexplicable, the original _qualities_ of things and the _natural forces_ which play a prominent part among them, by virtue of which they produce a specific kind of effect, _e.g._, weight, hardness, impulsive force, elasticity, warmth, electricity, chemical forces, &c., and which now remain in every explanation which is given, like an unknown quant.i.ty, which absolutely cannot be eliminated, in an otherwise perfectly solved algebraical equation. Accordingly there is no fragment of clay, however little worth, that is not entirely composed of inexplicable qualities. Thus these two inevitable defects in every purely physical, _i.e._, causal, explanation show that such an explanation can only be _relative_, and that its whole method and nature cannot be the only one, the ultimate and thus the sufficient one, _i.e._, cannot be the method of explanation that can ever lead to the satisfactory solution of the difficult riddle of things, and to the true understanding of the world and existence; but that the physical explanation in general and as such requires further a _metaphysical_ explanation, which affords us the key to all its a.s.sumptions, but just on this account must necessarily follow quite a different path. The first step to this is that one should bring to distinct consciousness and firmly retain the difference of the two, hence the difference between _physics_ and _metaphysics_. It rests in general on the Kantian distinction between _phenomenon_ and _thing in itself_. Just because Kant held the latter to be absolutely unknowable, there was, according to him, no _metaphysics_, but merely immanent knowledge, _i.e._, _physics_, which throughout can speak only of phenomena, and also a critique of the reason which strives after metaphysics. Here, however, in order to show the true point of connection between my philosophy and that of Kant, I shall antic.i.p.ate the second book, and give prominence to the fact that Kant, in his beautiful exposition of the compatibility of freedom and necessity (Critique of Pure Reason, first edition, p. 532-554; and Critique of Practical Reason, p. 224-231 of Rosenkranz's edition), shows how one and the same action may in one aspect be perfectly explicable as necessarily arising from the character of the man, the influence to which he has been subject in the course of his life, and the motives which are now present to him, but yet in another aspect must be regarded as the work of his free will; and in the same sense he says, -- 53 of the "Prolegomena:" "Certainly natural necessity will belong to every connection of cause and effect in the world of sense; yet, on the other hand, freedom will be conceded to that cause which is not itself a phenomenon (though indeed it is the ground of phenomena), thus nature and freedom may without contradiction be attributed to the same thing, but in a different reference-in the one case as a phenomenon, in the other case as a thing in itself." What, then, Kant teaches of the phenomenon of man and his action my teaching extends to _all_ phenomena in nature, in that it makes the _will_ as a thing in itself their foundation. This proceeding is justified first of all by the fact that it must not be a.s.sumed that man is specifically _toto genere_ radically different from the other beings and things in nature, but rather that he is different only in degree. I turn back from this premature digression to our consideration of the inadequacy of physics to afford us the ultimate explanation of things. I say, then, everything certainly is physical, but yet nothing is explicable physically. As for the motion of the projected bullet, so also for the thinking of the brain, a physical explanation must ultimately be in itself possible, which would make the latter just as comprehensible as is the former. But even the former, which we imagine we understand so perfectly, is at bottom as obscure to us as the latter; for what the inner nature of expansion in s.p.a.ce may be-of impenetrability, mobility, hardness, elasticity, and gravity remains, after all physical explanations, a mystery, just as much as thought. But because in the case of thought the inexplicable appears most immediately, a spring was at once made here from physics to metaphysics, and a substance of quite a different kind from all corporeal substances was hypostatised-a soul was set up in the brain. But if one had not been so dull as only to be capable of being struck by the most remarkable of phenomena, one would have had to explain digestion by a soul in the stomach, vegetation by a soul in the plant, affinity by a soul in the reagents, nay, the falling of a stone by a soul in the stone. For the quality of every unorganised body is just as mysterious as the life in the living body. In the same way, therefore, the physical explanation strikes everywhere upon what is metaphysical, by which it is annihilated, _i.e._, it ceases to be explanation. Strictly speaking, it may be a.s.serted that no natural science really achieves anything more than what is also achieved by Botany: the bringing together of similars, cla.s.sification. A physical system which a.s.serted that its explanations of things-in the particular from causes, and in general from forces-were really sufficient, and thus exhausted the nature of the world, would be the true _Naturalism_. From Leucippus, Democritus, and Epicurus down to the _Systeme de la Nature_, and further, to Delamark, Cabanis, and to the materialism that has again been warmed up in the last few years, we can trace the persistent attempt to set up a _system of physics without metaphysics_, that is, a system which would make the phenomenon the thing in itself. But all their explanations seek to conceal from the explainers themselves and from others that they simply a.s.sume the princ.i.p.al matter without more ado. They endeavour to show that all phenomena, even those of mind, are physical. And they are right; only they do not see that all that is physical is in another aspect also metaphysical. But, without Kant, this is indeed difficult to see, for it presupposes the distinction of the phenomenon from the thing in itself. Yet without this Aristotle, much as he was inclined to empiricism, and far as he was removed from the Platonic hyper-physics, kept himself free from this limited point of view. He says: "?? e? ??? ? est? t?? ?te?a ??s?a pa?a ta? f?se? s??est????a?, ? f?s???

a? e?? p??t? ep?st??; e? de est? t?? ??s?a a????t??, a?t? p??te?a ?a?

f???s?f?a p??t?, ?a? ?a????? ??t??, ?t? p??t?; ?a? pe?? t?? ??t?s ? ??, ta?t?? a? e?? ?e???sa?." (_Si igitur non est aliqua alia substantia, prter eas, qu natura consistunt, physica profecto prima scientia esset: quodsi autem est aliqua substantia immobilis, hc prior et philosophia prima, et universalis sic, quod prima; et de ente, prout ens est, speculari hujus est_), "Metaph.," V. 1. Such an _absolute system of physics_ as is described above, which leaves room for no _metaphysics_, would make the _Natura naturata_ into the _Natura naturans_; it would be physics established on the throne of metaphysics, yet it would comport itself in this high position almost like Holberg's theatrical would-be politician who was made burgomaster. Indeed behind the reproach of atheism, in itself absurd, and for the most part malicious, there lies, as its inner meaning and truth, which gives it strength, the obscure conception of such an absolute system of physics without metaphysics.

Certainly such a system would necessarily be destructive of ethics; and while Theism has falsely been held to be inseparable from morality, this is really true only of _metaphysics in general_, _i.e._, of the knowledge that the order of nature is not the only and absolute order of things.

Therefore we may set up this as the necessary _Credo_ of all just and good men: "I believe in metaphysics." In this respect it is important and necessary that one should convince oneself of the untenable nature of an _absolute system of physics_, all the more as this, the true _naturalism_, is a point of view which of its own accord and ever anew presses itself upon a man, and can only be done away with through profound speculation.

In this respect, however, all kinds of systems and faiths, so far and so long as they are accepted, certainly serve as a subst.i.tute for such speculation. But that a fundamentally false view presses itself upon man of its own accord, and must first be skilfully removed, is explicable from the fact that the intellect is not originally intended to instruct us concerning the nature of things, but only to show us their relations, with reference to our will; it is, as we shall find in the second book, only the medium of motives. Now, that the world schematises itself in the intellect in a manner which exhibits quite a different order of things from the absolutely true one, because it shows us, not their kernel, but only their outer sh.e.l.l, happens accidentally, and cannot be used as a reproach to the intellect; all the less as it nevertheless finds in itself the means of rectifying this error, in that it arrives at the distinction between the phenomenal appearance and the inner being of things, which distinction existed in substance at all times, only for the most part was very imperfectly brought to consciousness, and therefore was inadequately expressed, indeed often appeared in strange clothing. The Christian mystics, when they call it the _light of nature_, declare the intellect to be inadequate to the comprehension of the true nature of things. It is, as it were, a mere surface force, like electricity, and does not penetrate to the inner being.

The insufficiency of pure naturalism appears, as we have said, first of all, on the empirical path itself, through the circ.u.mstance that every physical explanation explains the particular from its cause; but the chain of these causes, as we know _a priori_, and therefore with perfect certainty, runs back to infinity, so that absolutely no cause could ever be the first. Then, however, the effect of every cause is referred to a law of nature, and this finally to a force of nature, which now remains as the absolutely inexplicable. But this inexplicable, to which all phenomena of this so clearly given and naturally explicable world, from the highest to the lowest, are referred, just shows that the whole nature of such explanation is only conditional, as it were only _ex concessis_, and by no means the true and sufficient one; therefore I said above that physically everything and nothing is explicable. That absolutely inexplicable element which pervades all phenomena, which is most striking in the highest, _e.g._, in generation, but yet is just as truly present in the lowest, _e.g._, in mechanical phenomena, points to an entirely different kind of order of things lying at the foundation of the physical order, which is just what Kant calls the order of things in themselves, and which is the goal of metaphysics. But, secondly, the insufficiency of pure naturalism comes out clearly from that fundamental philosophical truth, which we have fully considered in the first half of this book, and which is also the theme of the "Critique of Pure Reason;" the truth that every _object_, both as regards its objective existence in general and as regards the manner (forms) of this existence, is throughout conditioned by the knowing _subject_, hence is merely a phenomenon, not a thing in itself. This is explained in -- 7 of the first volume, and it is there shown that nothing can be more clumsy than that, after the manner of all materialists, one should blindly take the objective as simply given in order to derive everything from it without paying any regard to the subjective, through which, however, nay, in which alone the former exists. Samples of this procedure are most readily afforded us by the fashionable materialism of our own day, which has thereby become a philosophy well suited for barbers' and apothecaries' apprentices. For it, in its innocence, matter, a.s.sumed without reflection as absolutely real, is the thing in self, and the one capacity of a thing in itself is impulsive force, for all other qualities can only be manifestations of this.

With naturalism, then, or the purely physical way of looking at things, we shall never attain our end; it is like a sum that never comes out. Causal series without beginning or end, fundamental forces which are inscrutable, endless s.p.a.ce, beginningless time, infinite divisibility of matter, and all this further conditioned by a knowing brain, in which alone it exists just like a dream, and without which it vanishes-const.i.tute the labyrinth in which naturalism leads us ceaselessly round. The height to which in our time the natural sciences have risen in this respect entirely throws into the shade all previous centuries, and is a summit which mankind reaches for the first time. But however great are the advances which _physics_ (understood in the wide sense of the ancients) may make, not the smallest step towards _metaphysics_ is thereby taken, just as a plane can never obtain cubical content by being indefinitely extended. For all such advances will only perfect our knowledge of the _phenomenon_; while _metaphysics_ strives to pa.s.s beyond the phenomenal appearance itself, to that which so appears. And if indeed it had the a.s.sistance of an entire and complete experience, it would, as regards the main point, be in no way advantaged by it. Nay, even if one wandered through all the planets and fixed stars, one would thereby have made no step in _metaphysics_. It is rather the case that the greatest advances of physics will make the need of metaphysics ever more felt; for it is just the corrected, extended, and more thorough knowledge of nature which, on the one hand, always undermines and ultimately overthrows the metaphysical a.s.sumptions which till then have prevailed, but, on the other hand, presents the problem of metaphysics itself more distinctly, more correctly, and more fully, and separates it more clearly from all that is merely physical; moreover, the more perfectly and accurately known nature of the particular thing more pressingly demands the explanation of the whole and the general, which, the more correctly, thoroughly, and completely it is known empirically, only presents itself as the more mysterious. Certainly the individual, simple investigator of nature, in a special branch of physics, does not at once become clearly conscious of all this; he rather sleeps contentedly by the side of his chosen maid, in the house of Odysseus, banishing all thoughts of Penelope (cf. ch. 12 at the end). Hence we see at the present day the _husk of nature_ investigated in its minutest details, the intestines of intestinal worms and the vermin of vermin known to a nicety.

But if some one comes, as, for example, I do, and speaks of the _kernel of nature_, they will not listen; they even think it has nothing to do with the matter, and go on sifting their husks. One finds oneself tempted to call that over-microscopical and micrological investigator of nature the cotquean of nature. But those persons who believe that crucibles and retorts are the true and only source of all wisdom are in their own way just as perverse as were formerly their antipodes the Scholastics. As the latter, absolutely confined to their abstract conceptions, used these as their weapons, neither knowing nor investigating anything outside them, so the former, absolutely confined to their empiricism, allow nothing to be true except what their eyes behold, and believe they can thus arrive at the ultimate ground of things, not discerning that between the phenomenon and that which manifests itself in it, the thing in itself, there is a deep gulf, a radical difference, which can only be cleared up by the knowledge and accurate delimitation of the subjective element of the phenomenon, and the insight that the ultimate and most important conclusions concerning the nature of things can only be drawn from self-consciousness; yet without all this one cannot advance a step beyond what is directly given to the senses, thus can get no further than to the problem. Yet, on the other hand, it is to be observed that the most perfect possible knowledge of nature is the corrected _statement of the problem_ of metaphysics. Therefore no one ought to venture upon this without having first acquired a knowledge of all the branches of natural science, which, though general, shall be thorough, clear, and connected.

For the problem must precede its solution. Then, however, the investigator must turn his glance inward; for the intellectual and ethical phenomena are more important than the physical, in the same proportion as, for example, animal magnetism is a far more important phenomenon than mineral magnetism. The last fundamental secret man carries within himself, and this is accessible to him in the most immediate manner; therefore it is only here that he can hope to find the key to the riddle of the world and gain a clue to the nature of all things. The special province of metaphysics thus certainly lies in what has been called mental philosophy.

"The ranks of living creatures thou dost lead Before me, teaching me to know my brothers In air and water and the silent wood:

Then to the cave secure thou leadest me, Then show'st me mine own self, and in my breast The deep, mysterious miracles unfold."(28)

Finally, then, as regards the _source or the foundation_ of metaphysical knowledge, I have already declared myself above to be opposed to the a.s.sumption, which is even repeated by Kant, that it must lie _in mere conceptions_. In no knowledge can conceptions be what is first; for they are always derived from some perception. What has led, however, to that a.s.sumption is probably the example of mathematics. Mathematics can leave perception altogether, and, as is especially the case in algebra, trigonometry, and a.n.a.lysis, can operate with purely abstract conceptions, nay, with conceptions which are represented only by signs instead of words, and can yet arrive at a perfectly certain result, which is still so remote that any one who adhered to the firm ground of perception could not arrive at it. But the possibility of this depends, as Kant has clearly shown, on the fact that the conceptions of mathematics are derived from the most certain and definite of all perceptions, from the _a priori_ and yet intuitively known relations of quant.i.ty, and can therefore be constantly realised again and controlled by these, either arithmetically, by performing the calculations which are merely indicated by those signs, or geometrically, by means of what Kant calls the construction of the conceptions. This advantage, on the other hand, is not possessed by the conceptions out of which it was believed metaphysics could be built up; such, for example, as essence, being, substance, perfection, necessity, reality, finite, infinite, absolute, ground, &c. For such conceptions are by no means original, as fallen from heaven, or innate; but they also, like all conceptions, are derived from perceptions; and as, unlike the conceptions of mathematics, they do not contain the mere form of perception, but more, empirical perceptions must lie at their foundation.

Thus nothing can be drawn from them which the empirical perceptions did not also contain, that is, nothing which was not a matter of experience, and which, since these conceptions are very wide abstractions, we would receive with much greater certainty at first hand from experience. For from conceptions nothing more can ever be drawn than the perceptions from which they are derived contain. If we desire pure conceptions, _i.e._, such as have no empirical source, the only ones that can be produced are those which concern s.p.a.ce and time, _i.e._, the merely formal part of perception, consequently only the mathematical conceptions, or at most also the conception of causality, which indeed does not originate in experience, but yet only comes into consciousness by means of it (first in sense-perception); therefore experience indeed is only possible by means of it; but it also is only valid in the sphere of experience, on which account Kant has shown that it only serves to communicate the connection of experience, and not to transcend it; that thus it admits only of physical application, not of metaphysical. Certainly only its _a priori_ origin can give apodictic certainty to any knowledge; but this limits it to the mere _form_ of experience in general, for it shows that it is conditioned by the subjective nature of the intellect. Such knowledge, then, far from taking us beyond experience, gives only one _part_ of experience itself, the _formal_ part, which belongs to it throughout, and therefore is universal, consequently mere form without content. Since now metaphysics can least of all be confined to this, it must have also _empirical_ sources of knowledge; therefore that preconceived idea of a metaphysic to be found purely _a priori_ is necessarily vain. It is really a _pet.i.tio principii_ of Kant's, which he expresses most distinctly in -- 1 of the Prolegomena, that metaphysics must not draw its fundamental conceptions and principles from experience. In this it is a.s.sumed beforehand that only what we knew _before_ all experience can extend beyond all possible experience. Supported by this, Kant then comes and shows that all such knowledge is nothing more than the form of the intellect for the purpose of experience, and consequently can never lead beyond experience, from which he then rightly deduces the impossibility of all metaphysics. But does it not rather seem utterly perverse that in order to discover the secret of experience, _i.e._, of the world which alone lies before us, we should look quite away from it, ignore its content, and take and use for its material only the empty forms of which we are conscious _a priori_? Is it not rather in keeping with the matter that _the science of experience in general_, and as such, should also be drawn from experience? Its problem itself is given it empirically; why should not the solution of it call in the a.s.sistance of experience? Is it not senseless that he who speaks of the nature of things should not look at things themselves, but should confine himself to certain abstract conceptions? The task of metaphysics is certainly not the observation of particular experiences, but yet it is the correct explanation of experience as a whole. Its foundation must therefore, at any rate, be of an empirical nature. Indeed the _a priori_ nature of a part of human knowledge will be apprehended by it as a given _fact_, from which it will infer the subjective origin of the same. Only because the consciousness of its _a priori_ nature accompanies it is it called by Kant _transcendental_ as distinguished from _transcendent_, which signifies "pa.s.sing beyond all possibility of experience," and has its opposite in _immanent_, _i.e._, remaining within the limits of experience. I gladly recall the original meaning of this expression introduced by Kant, with which, as also with that of the Categories, and many others, the apes of philosophy carry on their game at the present day. Now, besides this, the source of the knowledge of metaphysics is not _outer_ experience alone, but also _inner_. Indeed, what is most peculiar to it, that by which the decisive step which alone can solve the great question becomes possible for it, consists, as I have fully and thoroughly proved in "_Ueber den Willen in der Natur_," under the heading, "_Physische Astronomie_," in this, that at the right place it combines outer experience with inner, and uses the latter as a key to the former.

The origin of metaphysics in empirical sources of knowledge, which is here set forth, and which cannot fairly be denied, deprives it certainly of that kind of apodictic certainty which is only possible through knowledge _a priori_. This remains the possession of logic and mathematics-sciences, however, which really only teach what every one knows already, though not distinctly. At most the primary elements of natural science may also be deduced from knowledge _a priori_. By this confession metaphysics only surrenders an ancient claim, which, according to what has been said above, rested upon misunderstanding, and against which the great diversity and changeableness of metaphysical systems, and also the constantly accompanying scepticism, in every age has testified. Yet against the possibility of metaphysics in general this changeableness cannot be urged, for the same thing affects just as much all branches of natural science, chemistry, physics, geology, zoology, &c., and even history has not remained exempt from it. But when once, as far as the limits of human intellect allow, a true system of metaphysics shall have been found, the unchangeableness of a science which is known _a priori_ will yet belong to it; for its foundation can only be _experience in general_, and not the particular and special experiences by which, on the other hand, the natural sciences are constantly modified and new material is always being provided for history. For experience as a whole and in general will never change its character for a new one.

The next question is: How can a science drawn from experience pa.s.s beyond it and so merit the name of metaphysics? It cannot do so perhaps in the same way as we find a fourth number from three proportionate ones, or a triangle from two sides and an angle. This was the way of the pre-Kantian dogmatism, which, according to certain laws known to us _a priori_, sought to reason from the given to the not given, from the consequent to the reason, thus from experience to that which could not possibly be given in any experience. Kant proved the impossibility of a metaphysic upon this path, in that he showed that although these laws were not drawn from experience, they were only valid for experience. He therefore rightly taught that in such a way we cannot transcend the possibility of all experience. But there are other paths to metaphysics. The whole of experience is like a cryptograph, and philosophy the deciphering of it, the correctness of which is proved by the connection appearing everywhere.

If this whole is only profoundly enough comprehended, and the inner experience is connected with the outer, it must be capable of being _interpreted_, _explained_ from itself. Since Kant has irrefutably proved to us that experience in general proceeds from two elements, the forms of knowledge and the inner nature of things, and that these two may be distinguished in experience from each other, as that of which we are conscious _a priori_ and that which is added _a posteriori_, it is possible, at least in general, to say, what in the given experience, which is primarily merely phenomenal, belongs to the _form_ of this phenomenon, conditioned by the intellect, and what, after deducting this, remains over for the _thing in itself_. And although no one can discern the thing in itself through the veil of the forms of perception, on the other hand every one carries it in himself, indeed is it himself; therefore in self-consciousness it must be in some way accessible to him, even though only conditionally. Thus the bridge by which metaphysics pa.s.ses beyond experience is nothing else than that a.n.a.lysis of experience into phenomenon and thing in itself in which I have placed Kant's greatest merit. For it contains the proof of a kernel of the phenomenon different from the phenomenon itself. This can indeed never be entirely separated from the phenomenon and regarded in itself as an _ens extramundanum_, but is always known only in its relations to and connections with the phenomenon itself. But the interpretation and explanation of the latter, in relation to the former, which is its inner kernel, is capable of affording us information with regard to it which does not otherwise come into consciousness. In this sense, then, metaphysics goes beyond the phenomenon, _i.e._, nature, to that which is concealed in or behind it (t?

eta t? f?s????), always regarding it, however, merely as that which manifests itself in the phenomenon, not as independent of all phenomenal appearance; it therefore remains immanent, and does not become transcendent. For it never disengages itself entirely from experience, but remains merely its interpretation and explanation, since it never speaks of the thing in itself otherwise than in its relation to the phenomenon.

This at least is the sense in which I, with reference throughout to the limitations of human knowledge proved by Kant, have attempted to solve the problem of metaphysics. Therefore his Prolegomena to future metaphysics will be valid and suitable for mine also. Accordingly it never really goes beyond experience, but only discloses the true understanding of the world which lies before it in experience. It is neither, according to the definition of metaphysics which even Kant repeats, a science of mere conceptions, nor is it a system of deductions from _a priori_ principles, the uselessness of which for the _end_ of metaphysics has been shown by Kant. But it is rational knowledge, drawn from perception of the external actual world and the information which the most intimate fact of self-consciousness affords us concerning it, deposited in distinct conceptions. It is accordingly the science of experience; but its subject and its source is not particular
