The defence of atoms might be conducted in this way. One may start from porosity and say something of this sort: All bodies have pores, and therefore so also have all parts of a body: now if this were carried out to infinity, there would ultimately be nothing left of a body but pores. The refutation would be that what remained over would certainly have to be assumed as without pores, and so far as absolutely dense, yet not on that account as consisting of absolutely indivisible particles, atoms; accordingly it would certainly be absolutely incompressible, but not absolutely indivisible. It would therefore be necessary that it should be asserted that the division of a body is only possible by penetrating into its pores; which, however, is entirely unproved. If, however, this is assumed, then we certainly have atoms, i. e., absolutely indivisible bodies, thus bodies of such strong cohesion of their spatial parts that no possible power can separate them: but then one may just as well assume such bodies to be large as small, and an atom might be as big as an ox, if it only would resist all possible attacks upon it.

Imagine two bodies of very different kinds, entirely freed from all pores by compression, as by means of hammering, or by pulverisation; – would their specific gravity then be the same? This would be the criterion of dynamics.

Chapter XXIV. On Matter

Matter has already been spoken of in the fourth chapter of the supplements to the first book, when we were considering the part of our knowledge of which we are conscious a priori. But it could only be considered there from a one-sided point of view, because we were then concerned merely with its relation to the forms of our intellect, and not to the thing in itself, and therefore we investigated it only from the subjective side, i. e., so far as it is an idea, and not from the objective side, i. e., with regard to what it may be in itself. In the first respect, our conclusion was that it is objective activity in general, yet conceived without fuller determination; therefore it takes the place of causality in the table of our a priori knowledge which is given there. For what is material is that which acts (the actual) in general, and regarded apart from the specific nature of its action. Hence also matter, merely as such, is not an object of perception, but only of thought, and thus is really an abstraction. It only comes into perception in connection with form and quality, as a body, i. e., as a fully determined kind of activity. It is only by abstracting from this fuller determination that we think of matter as such, i. e., separated from form and quality; consequently under matter we think of acting absolutely and in general, thus of activity in the abstract. The more fully determined acting we then conceive as the accident of matter; but only by means of this does matter become perceptible, i. e., present itself as a body and an object of experience. Pure matter, on the other hand, which, as I have shown in the Criticism of the Kantian Philosophy, alone constitutes the true and admissible content of the conception of substance, is causality itself, thought objectively, consequently as in space, and therefore filling it. Accordingly the whole being of matter consists in acting. Only thus does it occupy space and last in time. It is through and through pure causality. Therefore wherever there is action there is matter, and the material is the active in general. But causality itself is the form of our understanding; for it is known to us a priori, as well as time and space. Thus matter also, so far and up to this point, belongs to the formal part of our knowledge, and is consequently that form of the understanding, causality itself, bound up with space and time, hence objectified, i. e., conceived as that which fills space. (The fuller explanation of this doctrine will be found in the second edition of the essay on the principle of sufficient reason, p. 77; third edition, p. 82.) So far, however, matter is properly not the object but the condition of experience; like the pure understanding itself, whose function it so far is. Therefore of pure matter there is also only a conception, no perception. It enters into all external experience as a necessary constituent part of it; yet it cannot be given in any experience, but is only thought, and thought indeed as that which is absolutely inert, inactive, formless, and without qualities, and which is yet the supporter of all forms, qualities, and effects. Accordingly, of all fleeting phenomena, thus of all manifestations of natural forces and all living beings, matter is the permanent substratum which is necessarily produced by the forms of our intellect in which the world as idea exhibits itself. As such, and as having sprung from the forms of the intellect, it is entirely indifferent to those phenomena themselves, i. e., it is just as ready to be the supporter of this force of nature as of that, whenever, under the guidance of causality, the necessary conditions appear; while it itself, just because its existence is really only formal, i. e., is founded in the intellect must be thought as that which under all that change is absolutely permanent, thus with regard to time is without beginning and without end. This is why we cannot give up the thought that anything may be made out of anything, for example, gold out of lead; for this would only require that we should find out and bring about the intermediate states which matter, in itself indifferent, would have to pass through upon that path. For a priori we can never see why the same matter which is now the supporter of the quality lead could not some time become the supporter of the quality gold. Matter, as that which is only thought a priori, is distinguished from the a priori intuitions or perceptions proper by the fact that we can also think it entirely away; space and time, on the contrary, never. But this only shows that we can present to ourselves space and time in imagination without matter. For the matter which has once been placed in them, and accordingly thought as existing, we can never again absolutely think away, i. e., imagine it as vanished and annihilated, but are always forced to think of it merely as transferred to another space. So far, then, matter is as inseparably connected with our faculty of knowledge as space and time themselves. Yet even the difference that it must first be voluntarily thought as existing indicates that it does not belong so entirely and in every regard to the formal part of our knowledge as space and time, but also contains an element which is only given a posteriori. It is, in fact, the point of connection of the empirical part of our knowledge with the pure and a priori part, consequently the peculiar foundation-stone of the world of experience.

Only where all a priori assertions cease, therefore in the entirely empirical part of our knowledge of bodies, in their form, quality, and definite manner of acting, does that will reveal itself which we have already recognised and established as the true inner nature of things. But these forms and qualities always appear only as the properties and manifestations of that very matter the existence and nature of which depends upon the subjective forms of our intellect, i. e., they only become visible in it, and therefore by means of it. For that which always exhibits itself to us is only matter acting in some specially determined manner. Out of the inner properties of such matter, properties which cannot be further explained, proceeds every definite kind of effect of given bodies; and yet the matter itself is never perceived, but only these effects, and the definite properties which lie at their foundation, after separating which, matter, as that which then remains over, is necessarily added in thought by us; for, according to the exposition given above, it is objectified causality itself. Accordingly matter is that whereby the will, which constitutes the inner nature of things, becomes capable of being apprehended, perceptible, visible. In this sense, then, matter is simply the visibility of the will, or the bond between the world as will and the world as idea. It belongs to the latter inasmuch as it is the product of the functions of the intellect, to the former inasmuch as that which manifests itself in all material existences, i. e., phenomena is the will. Therefore every object is, as thing in itself, will, and as phenomenon, matter. If we could strip any given matter of all the properties that come to it a priori, i. e., of all the forms of our perception and apprehension, we would have left the thing in itself, that which, by means of those forms, appears as the purely empirical in matter, but which would then itself no longer appear as something extended and active; i. e., we would no longer have matter before us, but the will. This very thing in itself, or the will, in that it becomes a phenomenon, i. e., enters the forms of our intellect, appears as matter, i. e., as the invisible but necessarily assumed supporter of the properties which are only visible through it. In this sense, then, matter is the visibility of the will. Consequently Plotinus and Giordano Bruno were right, not only in their sense but also in ours, when they made the paradoxical assertion already referred to in chapter 4: Matter itself is not extended, consequently it is incorporeal. For space, which is our form of perception, imparts extension to matter, and corporeal existence consists in acting, which depends upon causality, and consequently upon the form of our understanding. On the other hand, every definite property, thus everything empirical in matter, even gravity, depends upon that which only becomes visible by means of matter, the thing in itself, the will. Gravity is yet the lowest of all grades of the objectification of the will; therefore it appears in all matter without exception, thus is inseparable from matter in general. Yet, just because it is a manifestation of the will, it belongs to knowledge a posteriori, not to knowledge a priori. Therefore we can always picture to ourselves matter without weight, but not without extension, repulsive force, and stability, for then it would be without impenetrability, and consequently would not occupy space, i. e., it would be without the power of acting; but the nature of matter as such just consists in acting, i. e., in causality in general; and causality depends upon the a priori form of our understanding, and therefore cannot be thought away.

Matter is accordingly the will itself, but no longer in itself, but so far as it is perceived, i. e., assumes the form of the objective idea. Thus what objectively is matter is subjectively will. Exactly corresponding to this, as was proved above, our body is just the visibility, objectivity of our will, and so also every body is the objectivity of the will at some one of its grades. Whenever the will exhibits itself to objective knowledge it enters into the forms of perception of the intellect, time, space, and causality. But on account of this it exists at once as a material object. We can present to our minds form without matter, but not the reverse; because matter deprived of form would be the will itself, and the will only becomes objective by entering the forms of perception of our intellect, and therefore only by means of the assumption of form. Space is the form of perception of matter because the latter is the substance (Stoff) of mere form, but matter can appear only in form.

Since the will becomes objective, i. e., passes over into the idea, matter is the universal substratum of this objectification, or rather it is this objectification itself taken abstractly, i. e., regarded apart from all form. Matter is accordingly the visibility of the will in general, while the character of its definite manifestations has its expression in form and quality. Hence what in the manifestation, i. e., for the idea, is matter is in itself will. Therefore, under the conditions of experience and perception, everything holds good of it that holds good of the will in itself, and it repeats all the relations and properties of the will in temporal images. Accordingly it is the substance of the world of perception, as the will is the inner nature of all things. The forms are innumerable, the matter is one; just as the will is one in all its objectifications. As the will never objectifies itself as general, i. e., as absolute will, but always as particular, i. e., under special determinations and a given character, so matter never appears as such, but always in connection with some particular form and quality. In the manifestation or objectification of the will matter represents its totality, it itself, which in all is one, as matter is one in all bodies. As the will is the inmost kernel of all phenomenal beings, so matter is the substance which remains after all the accidents have been taken away. As the will is that which is absolutely indestructible in all existence, so matter is that which is imperishable in time and permanent through all changes. That matter for itself, thus separated from form, cannot be perceived or presented in imagination depends upon the fact that in itself, and as the pure substantiality of bodies, it is really the will itself. But the will cannot be apprehended objectively, or perceived in itself, but only under all the conditions of the idea, and therefore only as phenomenon. Under these conditions, however, it exhibits itself at once as body, i. e., as matter clothed in form and quality. But form is conditioned by space, and quality or power of acting by causality; thus both depend upon the functions of the intellect. Matter without them would just be the thing in itself, i. e., the will itself. Therefore, as has been said, Plotinus and Giordano Bruno could only be brought by a completely objective path to the assertion that matter in and for itself is without extension, consequently without spatial properties, consequently incorporeal.

Because, then, matter is the visibility of the will, and every force in itself is will, no force can appear without a material substratum, and conversely no body can be without forces dwelling in it which constitute its quality. Therefore a body is the union of matter and form which is called substance (Stoff). Force and substance are inseparable because at bottom they are one; for, as Kant has shown, matter itself is given us only as the union of two forces, the force of expansion and that of attraction. Thus there is no opposition between force and substance, rather they are precisely one.

Led by the course of our consideration to this standpoint, and having attained to this metaphysical view of matter, we will confess without reluctance that the temporal origin of forms, shapes, or species cannot reasonably be sought elsewhere than in matter. Some time or other they must have come forth from it, just because it is the mere visibility of the will which constitutes the inner nature of all phenomena. In that the will manifests itself, i. e., presents itself objectively to the intellect, matter, as its visibility, assumes form by means of the functions of the intellect. Hence the Schoolmen said: “Materia appetit formam.” That such was the origin of all forms of life cannot be doubted: we cannot even conceive it otherwise. Whether, however, now, since the paths to the perpetuation of the forms stand open, and are secured and sustained by nature with boundless care and jealousy, generatio œquivoca still takes place, can only be decided by experience; especially since the saying, Natura nihil facit frustra, might, with reference to the paths of regular propagation, be used as a valid argument against it. Yet in spite of the most recent objections to it, I hold that at very low grades generatio œquivoca is very probable, and primarily indeed in the case of entozoa and epizoa, particularly such as appear in consequence of special cachexia of the animal organism. For the conditions of their life only appear exceptionally; consequently their species cannot propagate itself in the regular manner, and therefore has always to arise anew whenever opportunity offers. Therefore as soon as the conditions of life of epizoa have appeared in consequence of certain chronic diseases, or cachexia, and in accordance with them, pediculus capitis or pubis or corporis appears entirely of itself, and without any egg; and this notwithstanding the complex structure of these insects, for the putrefaction of a living animal body affords material for higher productions than that of hay in water, which only produces infusoria. Or is it thought more likely that the eggs of the epizoa are constantly floating about in the air in expectation? (Fearful to think of!) Let us rather remember the disease of phthiriasis, which occurs even now. An analogous case takes place when through special circumstances the conditions of life appear of a species which up till then was foreign to that place. Thus August St. Hilaire saw in Brazil, after the burning of a primitive forest, as soon as ever the ashes had cooled, a number of plants grow up out of them, the species of which was not to be found far and wide; and quite recently Admiral Petit-Thouars informed the Académie des sciences that upon the growing coral islands in Polynesia a soil gradually deposits itself which is now dry, now lies in water, and which vegetation soon takes possession of, bringing forth trees which are absolutely peculiar to these islands (Comptes rendus, 17th Jan. 1859, p. 147). Whenever putrefaction takes place mould, fungi, and in liquids infusoria appear. The assumption now in favour that spores and eggs of the innumerable species of all those kinds of animal life are everywhere floating in the air, and wait through long years for a favourable opportunity, is more paradoxical than that of generatio œquivoca. Putrefaction is the decomposition of an organised body, first into its more immediate chemical constituents. Since now these are more or less the same in all living beings, the omnipresent will to live can possess itself of them, in order, in accordance with the circumstances, to produce new existences from them; and these forming themselves according to design, i. e., objectifying the volition of the will at the time, solidify out of the chemical elements as the chicken out of the fluidity of the egg. When, however, this does not take place, the putrefying matter is resolved into its ultimate constituent parts, which are the chemical elements, and now passes over again into the great course of nature. The war which has been waged for the last ten or fifteen years against generatio œquivoca, with its premature shouts of victory, was the prelude to the denial of the vital force, and related to it. Let no one, however, be deceived by dogmatic assertions and brazen assurances that the questions are decided, settled, and generally recognised. On the contrary, the whole mechanical and atomistic view of nature is approaching its bankruptcy, and its defenders have to learn that something more is concealed behind nature than action and reaction. The reality of generatio œquivoca and the folly of the extraordinary assumption that in the atmosphere, everywhere and always, billions of seeds of all possible kinds of fungi, and eggs of all possible kinds of infusoria, are floating about, till now one and then another by chance finds its suitable medium, has quite recently (1859) been thoroughly and victoriously shown by Pouchet before the French Academy, to the great vexation of the other members.

Our wonder at the origin of forms in matter is at bottom like that of the savage who looks for the first time in a mirror and marvels at his own image which he sees there. For our own inner nature is the will, whose mere visibility is matter. Yet matter never appears otherwise than with the visible, i. e., under the outer shell of form and quality, and therefore is never directly apprehended, but always merely added in thought as that which is identical in all things, under all differences of quality and form. On this account it is more a metaphysical than a physical principle of explanation of things, and to make all existences arise from it is really to explain them from something which is very mysterious; which all know it to be except those who confound attacking with comprehending. In truth, the ultimate and exhaustive explanation of things is by no means to be sought in matter, although certainly the temporal origin both of unorganised forms and of organised beings is to be sought in it. Yet it seems that the origination of organised forms, the production of the species themselves, is almost as difficult for nature to accomplish as it is for us to comprehend. This is indicated by the entirely extravagant provision which nature always makes for maintaining the species which once exist. Yet on the present surface of this planet the will to live has gone through the scale of its objectification three times, quite independently of each other, in a different modulation, and also with great difference of perfection and fulness. The old world, America, and Australia have, it is well known, each their peculiar independent fauna, entirely different from that of the other two. Upon each of these great continents the species are throughout different, but yet, because all three belong to the same planet, they have a thorough analogy with each other running parallel through them; therefore the genera are for the most part the same. In Australia this analogy can only be very imperfectly followed because its fauna is very poor in mammalia, and contains neither beasts of prey nor apes. On the other hand, between the old world and America it is obvious, and in the following manner. In mammals America always produces the inferior analogue, but in birds and reptiles the better. Thus it has the advantage in the condor, the macaw, the humming-bird, and the largest batrachia and ophidia; but, for example, instead of the elephant it has only the tapir, instead of the lion the puma, instead of the tiger the jaguar, instead of the camel the lama, and instead of apes proper only monkeys. Even from this last defect it may be concluded that in America nature was not able to rise to man; for even from the nearest grade below man, the chimpanzee and the orang-outang or pongo, the step to man was still an excessively great one. Correspondingly we find that the three races of men which, both upon physiological and linguistic grounds, are undoubtedly equally original, the Caucasian, the Mongolian, and the Ethiopian, are only at home in the old world; while America, on the other hand, is peopled by a mixed or climatically modified Mongolian race, which must have come over from Asia. On the surface of the earth which immediately preceded the present surface apes were reached here and there, but not men.

From this standpoint of our consideration, which shows us matter as the direct visibility of the will which manifests itself in all things, nay, indeed, for the merely physical investigation which follows the guidance of time and causality, lets it pass as the origin of things, we are easily led to the question whether even in philosophy we could not just as well start from the objective as from the subjective side, and accordingly set up as the fundamental truth the proposition: “There is in general nothing but matter and its indwelling forces.” But, with regard to these “indwelling forces” here so easily used, we must remember that their assumption leads every explanation back to a completely incomprehensible miracle, and then leaves it beside it, or rather leaves it to begin from it. For every definite, inexplicable force of nature which lies at the foundation of the most different kinds of effects of an unorganised body, not less than the vital force which manifests itself in every organised body, is such an incomprehensible miracle, as I have fully explained in chap. 17, and have also shown that physics can never be set upon the throne of metaphysics, just because it leaves quite untouched the assumption referred to and also many others; whereby from the beginning it renounces all claim to give an ultimate explanation of things. I must further remind the reader here of the proof of the insufficiency of materialism, which is given towards the end of the first chapter, because, as was said there, it is the philosophy of the subject which forgets itself in its calculation. But all these truths rest upon the fact that everything objective, everything external, since it is always only something apprehended, something known, remains also always indirect and secondary, therefore absolutely never can become the ultimate ground of explanation of things or the starting-point of philosophy. Philosophy necessarily requires what is absolutely immediate for its starting-point. But clearly only that which is given in self-consciousness fulfils this condition, that which is within, the subjective. And hence it is so eminent a merit of Descartes that he first made philosophy start from self-consciousness. Since then, upon this path, the genuine philosophers, especially Locke, Berkeley, and Kant, have gone even further, each in his own manner, and in consequence of their investigations I was led to recognise and make use, not of one, but of two completely different data of immediate knowledge in self-consciousness, the idea and the will, by the combined application of which one can go further in philosophy, in the same proportion as in the case of an algebraical problem one can accomplish more if two known quantities are given than if only one is given.

In accordance with what has been said, the ineradicable falseness of materialism primarily consists in the fact that it starts from a petitio principii, which when more closely considered turns out indeed to be a πρωτον φευδος. It starts from the assumption that matter is something absolutely and unconditionally given, something existing independently of the knowledge of the subject, thus really a thing in itself. It attributes to matter (and consequently also to its presuppositions time and space) an absolute existence, i. e., an existence independent of the perceiving subject; this is its fundamental error. Then, if it will go honestly to work, it must leave the qualities inherent in the given materials, i. e., in the substances, together with the natural forces which manifest themselves in these, and finally also the vital force, unexplained, as unfathomable qualitates occultæ, and start from them; as physics and physiology actually do, because they make no claim to be the ultimate explanation of things. But just to avoid this, materialism – at least as it has hitherto appeared – has not proceeded honestly. It denies all those original forces, for it pretends and seems to reduce them all, and ultimately also the vital force, to the mere mechanical activity of matter, thus to manifestations of impenetrability, form, cohesion, impulsive power, inertia, gravity, &c., qualities which certainly have least that is inexplicable in themselves, just because they partly depend upon what is known a priori, consequently on the forms of our own intellect, which are the principle of all comprehensibility. But the intellect as the condition of all objects, and consequently of the whole phenomenal world, is entirely ignored by materialism. Its plan is now to refer everything qualitative to something merely quantitative, for it attributes the former to mere form in opposition to matter proper. To matter it leaves, of the properly empirical qualities, only gravity, because it already appears as something quantitative, the only measure of the quantity of the matter. This path necessarily leads it to the fiction of atoms, which now become the material out of which it thinks to construct the mysterious manifestations of all original forces. But here it has really no longer to do with empirically given matter, but with a matter which is not to be found in rerum natura, but is rather a mere abstraction of that real matter, a matter which would absolutely have no other than those mechanical qualities which, with the exception of gravity, can be pretty well construed a priori, just because they depend upon the forms of space, time, and causality, and consequently upon our intellect; to this poor material, then, it finds itself reduced for the construction of its castle in the air.

In this way it inevitably becomes atomism; as happened to it already in its childhood in the hands of Leucippus and Democritus, and happens to it again now that it has come to a second childhood through age; with the French because they have never known the Kantian philosophy, and with the Germans because they have forgotten it. And indeed it carries it further in this its second childhood than in its first. Not merely solid bodies are supposed to consist of atoms, but liquids, water, air, gas, nay, even light, which is supposed to be the undulations of a completely hypothetical and altogether unproved ether, consisting of atoms, the difference of the rapidity of these undulations causing colours. This is an hypothesis which, like the earlier Newtonian seven-colour theory, starts from an analogy with music, entirely arbitrarily assumed, and then violently carried out. One must really be credulous to an unheard-of degree to let oneself be persuaded that the innumerable different ether vibrations proceeding from the infinite multiplicity of coloured surfaces in this varied world could constantly, and each in its own time, run through and everywhere cross each other without ever disturbing each other, but should rather produce through such tumult and confusion the profoundly peaceful aspect of illumined nature and art. Credat Judæus Apella! Certainly the nature of light is to us a secret; but it is better to confess this than to bar the way of future knowledge by bad theories. That light is something quite different from a mere mechanical movement, undulation, or vibration and tremor, indeed that it is material, is shown by its chemical effects, a beautiful series of which was recently laid before the Académie des sciences by Chevreul, who let sunlight act upon different coloured materials. The most beautiful thing in these experiments is, that a white roll of paper which has been exposed to the sunlight exhibits the same effects, nay, does so even after six months, if during this time it has been secured in a firmly closed metal tube. Has, then, the tremulation paused for six months, and does it now fall into time again? (Comptes rendus of 20th December 1858.) This whole hypothesis of vibrating ether atoms is not only a chimera, but equals in awkward crudeness the worst of Democritus, and yet is shameless enough, at the present day, to profess to be an established fact, and has thus brought it about that it is orthodoxly repeated by a thousand stupid scribblers of all kinds, who are devoid of all knowledge of such things, and is believed in as a gospel. But the doctrine of atoms in general goes still further: it is soon a case of Spartam, quam nactus es, orna! Different perpetual motions are then ascribed to all the atoms, revolving, vibrating, &c., according to the office of each; in the same way every atom has its atmosphere of ether, or something else, and whatever other similar fancies there may be. The fancies of Schelling's philosophy of nature and its disciples were for the most part ingenious, lofty, or at least witty; but these, on the contrary, are clumsy, insipid, paltry, and awkward, the production of minds which, in the first place, are unable to think any other reality than a fabulous, qualityless matter, which is also an absolute object, i. e., an object without a subject; and secondly can think of no other activity than motion and impact: these two alone are comprehensible to them, and that everything runs back to these is their a priori assumption; for these are their thing in itself. To attain this end the vital force is reduced to chemical forces (which are insidiously and unjustifiably called molecular forces), and all processes of unorganised nature to mechanism, i. e., to action and reaction. And thus at last the whole world and everything in it becomes merely a piece of mechanical ingenuity, like the toys worked by levers, wheels, and sand, which represent a mine or the work on a farm. The source of the evil is, that through the amount of hand-work which experimenting requires the head-work of thinking has been allowed to get out of practice. The crucible and the voltaic pile are supposed to assume its functions; hence also the profound abhorrence of all philosophy.
