The World as Will and Idea (Vol. 2 of 3)

10. Upon what depends the identity of the person? Not upon the matter of the body; it is different after a few years. Not upon its form, which changes as a whole and in all its parts; all but the expression of the glance, by which, therefore, we still know a man even after many years; which proves that in spite of all changes time produces in him something in him remains quite untouched by it. It is just this by which we recognise him even after the longest intervals of time, and find the former man entire. It is the same with ourselves, for, however old we become, we yet feel within that we are entirely the same as we were when we were young, nay, when we were still children. This, which unaltered always remains quite the same, and does not grow old along with us, is really the kernel of our nature, which does not lie in time. It is assumed that the identity of the person rests upon that of consciousness. But by this is understood merely the connected recollection of the course of life; hence it is not sufficient. We certainly know something more of our life than of a novel we have formerly read, yet only very little. The principal events, the interesting scenes, have impressed themselves upon us; in the remainder a thousand events are forgotten for one that has been retained. The older we become the more do things pass by us without leaving any trace. Great age, illness, injury of the brain, madness, may deprive us of memory altogether, but the identity of the person is not thereby lost. It rests upon the identical will and the unalterable character of the person. It is it also which makes the expression of the glance unchangeable. In the heart is the man, not in the head. It is true that, in consequence of our relation to the external world, we are accustomed to regard as our real self the subject of knowledge, the knowing I, which wearies in the evening, vanishes in sleep, and in the morning shines brighter with renewed strength. This is, however, the mere function of the brain, and not our own self. Our true self, the kernel of our nature, is what is behind that, and really knows nothing but willing and not willing, being content and not content, with all the modifications of this, which are called feelings, emotions, and passions. This is that which produces the other, does not sleep with it when it sleeps, and in the same way when it sinks in death remains uninjured. Everything, on the contrary, that belongs to knowledge is exposed to oblivion; even actions of moral significance can sometimes, after years, be only imperfectly recalled, and we no longer know accurately and in detail how we acted on a critical occasion. But the character itself, to which the actions only testify, cannot be forgotten by us; it is now still quite the same as then. The will itself, alone and for itself, is permanent, for it alone is unchangeable, indestructible, not growing old, not physical, but metaphysical, not belonging to the phenomenal appearance, but to that itself which so appears. How the identity of consciousness also, so far as it goes, depends upon it I have shown above in chapter 15, so I need not dwell upon it further here.

11. Aristotle says in passing, in his book on the comparison of the desirable, “To live well is better than to live” (βελτιον του ζῃν το ευ ζῃν, Top. iii. 2). From this we might infer, by double contraposition, not to live is better than to live badly. This is also evident to the intellect; yet the great majority live very badly rather than not at all. This clinging to life cannot therefore have its ground in the object of life, since life, as was shown in the fourth book, is really a constant suffering, or at the least, as will be shown further on in the 28th chapter, a business which does not cover its expenses; thus that clinging to life can only be founded in the subject of it. But it is not founded in the intellect, it is no result of reflection, and in general is not a matter of choice; but this willing of life is something that is taken for granted: it is a prius of the intellect itself. We ourselves are the will to live, and therefore we must live, well or ill. Only from the fact that this clinging to a life which is so little worth to them is entirely a priori and not a posteriori can we explain the excessive fear of death that dwells in every living thing, which Rochefoucauld has expressed in his last reflection, with rare frankness and naïveté, and upon which the effect of all tragedies and heroic actions ultimately rest, for it would be lost if we prized life only according to its objective worth. Upon this inexpressible horror mortis is also founded the favourite principle of all ordinary minds, that whosoever takes his own life must be mad; yet not less the astonishment, mingled with a certain admiration, which this action always excites even in thinking minds, because it is so opposed to the nature of all living beings that in a certain sense we are forced to admire him who is able to perform it. For suicide proceeds from a purpose of the intellect, but our will to live is a prius of the intellect. Thus this consideration also, which will be fully discussed in chapter 28, confirms the primacy of the will in self-consciousness.

12. On the other hand, nothing proves more clearly the secondary, dependent, conditioned nature of the intellect than its periodical intermittance. In deep sleep all knowing and forming of ideas ceases. But the kernel of our nature, the metaphysical part of it which the organic functions necessarily presuppose as their primum mobile, must never pause if life is not to cease, and, moreover, as something metaphysical and therefore incorporeal, it requires no rest. Therefore the philosophers who set up a soul as this metaphysical kernel, i. e., an originally and essentially knowing being, see themselves forced to the assertion that this soul is quite untiring in its perceiving and knowing, therefore continues these even in deep sleep; only that we have no recollection of this when we awake. The falseness of this assertion, however, was easy to see whenever one had rejected that soul in consequence of Kant's teaching. For sleep and waking prove to the unprejudiced mind in the clearest manner that knowing is a secondary function and conditioned by the organism, just like any other. Only the heart is untiring, because its beating and the circulation of the blood are not directly conditioned by nerves, but are just the original manifestation of the will. Also all other physiological functions governed merely by ganglionic nerves, which have only a very indirect and distant connection with the brain, are carried on during sleep, although the secretions take place more slowly; the beating of the heart itself, on account of its dependence upon respiration, which is conditioned by the cerebral system (medulla oblongata), becomes with it a little slower. The stomach is perhaps most active in sleep, which is to be attributed to its special consensus with the now resting brain, which occasions mutual disturbances. The brain alone, and with it knowing, pauses entirely in deep sleep. For it is merely the minister of foreign affairs, as the ganglion system is the minister of the interior. The brain, with its function of knowing, is only a vedette established by the will for its external ends, which, up in the watch-tower of the head, looks round through the windows of the senses and marks where mischief threatens and where advantages are to be looked for, and in accordance with whose report the will decides. This vedette, like every one engaged on active service, is then in a condition of strain and effort, and therefore it is glad when, after its watch is completed, it is again withdrawn, as every watch gladly retires from its post. This withdrawal is going to sleep, which is therefore so sweet and agreeable, and to which we are so glad to yield; on the other hand, being roused from sleep is unwelcome, because it recalls the vedette suddenly to its post. One generally feels also after the beneficent systole the reappearance of the difficult diastole, the reseparation of the intellect from the will. A so-called soul, which was originally and radically a knowing being, would, on the contrary, necessarily feel on awaking like a fish put back into water. In sleep, when merely the vegetative life is carried on, the will works only according to its original and essential nature, undisturbed from without, with no diminution of its power through the activity of the brain and the exertion of knowing, which is the heaviest organic function, yet for the organism merely a means, not an end; therefore, in sleep the whole power of the will is directed to the maintenance and, where it is necessary, the improvement of the organism. Hence all healing, all favourable crises, take place in sleep; for the vis naturæ medicatrix has free play only when it is delivered from the burden of the function of knowledge. The embryo which has still to form the body therefore sleeps continuously, and the new-born child the greater part of its time. In this sense Burdach (Physiologie, vol. iii. p. 484) quite rightly declares sleep to be the original state.

With reference to the brain itself, I account to myself for the necessity of sleep more fully through an hypothesis which appears to have been first set up in Neumann's book, “Von den Krankheiten des Menschen,” 1834, vol. 4, § 216. It is this, that the nutrition of the brain, thus the renewal of its substance from the blood, cannot go on while we are awake, because the very eminent organic function of knowing and thinking would be disturbed or put an end to by the low and material function of nutrition. This explains the fact that sleep is not a purely negative condition, a mere pausing of the activity of the brain, but also shows a positive character. This makes itself known through the circumstance that between sleep and waking there is no mere difference of degree, but a fixed boundary, which, as soon as sleep intervenes, declares itself in dreams which are completely different from our immediately preceding thoughts. A further proof of this is that when we have dreams which frighten us we try in vain to cry out, or to ward off attacks, or to shake off sleep; so that it is as if the connecting-link between the brain and the motor nerves, or between the cerebrum and the cerebellum (as the regulator of movements) were abolished; for the brain remains in its isolation and sleep holds us fast as with brazen claws. Finally, the positive character of sleep can be seen in the fact that a certain degree of strength is required for sleeping. Therefore too great fatigue or natural weakness prevent us from seizing it, capere somnum. This may be explained from the fact that the process of nutrition must be introduced if sleep is to ensue: the brain must, as it were, begin to feed. Moreover, the increased flow of blood into the brain during sleep is explicable from the nutritive process; and also the position of the arms laid together above the head, which is instinctively assumed because it furthers this process: also why children, so long as their brain is still growing, require a great deal of sleep, while in old age, on the other hand, when a certain atrophy of the brain, as of all the parts, takes place, sleep is short; and finally why excessive sleep produces a certain dulness of consciousness, the consequence of a certain hypertrophy of the brain, which in the case of habitual excess of sleep may become permanent and produce imbecility: ανιη και πολυς ὑπνος (noxæ est etiam multus somnus), Od. 15, 394. The need of sleep is therefore directly proportionate to the intensity of the brain-life, thus to the clearness of the consciousness. Those animals whose brain-life is weak and dull sleep little and lightly; for example, reptiles and fishes: and here I must remind the reader that the winter sleep is sleep almost only in name, for it is not an inaction of the brain alone, but of the whole organism, thus a kind of apparent death. Animals of considerable intelligence sleep deeply and long. Men also require more sleep the more developed, both as regards quantity and quality, and the more active their brain is. Montaigne relates of himself that he had always been a long sleeper, that he had passed a large part of his life in sleeping, and at an advanced age still slept from eight to nine hours at a time (Liv. iii., chap. 13). Descartes also is reported to have slept a great deal (Baillet, Vie de Descartes, 1693, p. 288). Kant allowed himself seven hours for sleep, but it was so hard for him to do with this that he ordered his servant to force him against his will, and without listening to his remonstrances, to get up at the set time (Jachmann, Immanuel Kant, p. 162). For the more completely awake a man is, i. e., the clearer and more lively his consciousness, the greater for him is the necessity of sleep, thus the deeper and longer he sleeps. Accordingly much thinking or hard brain-work increases the need of sleep. That sustained muscular exertion also makes us sleepy is to be explained from the fact that in this the brain continuously, by means of the medulla oblongata, the spinal marrow, and the motor nerves, imparts the stimulus to the muscles which affects their irritability, and in this way it exhausts its strength. The fatigue which we observe in the arms and legs has accordingly its real seat in the brain; just as the pain which these parts feel is really experienced in the brain; for it is connected with the motor nerves, as with the nerves of sense. The muscles which are not actuated from the brain – for example, those of the heart – accordingly never tire. The same grounds explain the fact that both during and after great muscular exertion we cannot think acutely. That one has far less energy of mind in summer than in winter is partly explicable from the fact that in summer one sleeps less; for the deeper one has slept, the more completely awake, the more lively, is one afterwards. This, however, must not mislead us into extending sleep unduly, for then it loses in intension, i. e., in deepness and soundness, what it gains in extension; whereby it becomes mere loss of time. This is what Goethe means when he says (in the second part of “Faust”) of morning slumber: “Sleep is husk: throw it off.” Thus in general the phenomenon of sleep most specially confirms the assertion that consciousness, apprehension, knowing, thinking, is nothing original in us, but a conditioned and secondary state. It is a luxury of nature, and indeed its highest, which it can therefore the less afford to pursue without interruption the higher the pitch to which it has been brought. It is the product, the efflorescence of the cerebral nerve-system, which is itself nourished like a parasite by the rest of the organism. This also agrees with what is shown in our third book, that knowing is so much the purer and more perfect the more it has freed and severed itself from the will, whereby the purely objective, the æsthetic comprehension appears. Just as an extract is so much the purer the more it has been separated from that out of which it is extracted and been cleared of all sediment. The opposite is shown by the will, whose most immediate manifestation is the whole organic life, and primarily the untiring heart.

This last consideration is related to the theme of the following chapter, to which it therefore makes the transition: yet the following observation belongs to it. In magnetic somnambulism the consciousness is doubled: two trains of knowledge, each connected in itself, but quite different from each other, arise; the waking consciousness knows nothing of the somnambulent. But the will retains in both the same character, and remains throughout identical; it expresses in both the same inclinations and aversions. For the function may be doubled, but not the true nature.

Chapter XX.34 Objectification Of The Will In The Animal Organism

By objectification I understand the self-exhibition in the real corporeal world. However, this world itself, as was fully shown in the first book and its supplements, is throughout conditioned by the knowing subject, thus by the intellect, and therefore as such is absolutely inconceivable outside the knowledge of this subject; for it primarily consists simply of ideas of perception, and as such is a phenomenon of the brain. After its removal the thing in itself would remain. That this is the will is the theme of the second book, and is there proved first of all in the human organism and in that of the brutes.

The knowledge of the external world may also be defined as the consciousness of other things, in opposition to self-consciousness. Since we have found in the latter that its true object or material is the will, we shall now, with the same intention, take into consideration the consciousness of other things, thus objective knowledge. Now here my thesis is this: that which in self-consciousness, thus subjectively is the intellect, presents itself in the consciousness of other things, thus objectively, as the brain; and that which in self-consciousness, thus subjectively, is the will, presents itself in the consciousness of other things, thus objectively, as the whole organism.

To the evidence which is given in support of this proposition, both in our second book and in the first two chapters of the treatise “Ueber den Willen in der Natur,” I add the following supplementary remarks and illustrations.

Nearly all that is necessary to establish the first part of this thesis has already been brought forward in the preceding chapter, for in the necessity of sleep, in the alterations that arise from age, and in the differences of the anatomical conformation, it was proved that the intellect is of a secondary nature, and depends absolutely upon a single organ, the brain, whose function it is, just as grasping is the function of the hand; that it is therefore physical, like digestion, not metaphysical, like the will. As good digestion requires a healthy, strong stomach, as athletic power requires muscular sinewy arms, so extraordinary intelligence requires an unusually developed, beautifully formed brain of exquisitely fine texture and animated by a vigorous pulse. The nature of the will, on the contrary, is dependent upon no organ, and can be prognosticated from none. The greatest error in Gall's phrenology is that he assigns organs of the brain for moral qualities also. Injuries to the head, with loss of brain substance, affect the intellect as a rule very disadvantageously: they result in complete or partial imbecility or forgetfulness of language, permanent or temporary, yet sometimes only of one language out of several which were known, also in the loss of other knowledge possessed, &c., &c. On the other hand, we never read that after a misfortune of this kind the character has undergone a change, that the man has perhaps become morally worse or better, or has lost certain inclinations or passions, or assumed new ones; never. For the will has not its seat in the brain, and moreover, as that which is metaphysical, it is the prius of the brain, as of the whole body, and therefore cannot be altered by injuries of the brain. According to an experiment made by Spallanzani and repeated by Voltaire,35 a snail that has had its head cut off remains alive, and after some weeks a new head grows on, together with horns; with this consciousness and ideas again appear; while till then the snail had only given evidence of blind will through unregulated movements. Thus here also we find the will as the substance which is permanent, the intellect, on the contrary, conditioned by its organ, as the changing accident. It may be defined as the regulator of the will.

It was perhaps Tiedemann who first compared the cerebral nervous system to a parasite (Tiedemann und Trevirann's Journal für Physiologie, Bd. i. § 62). The comparison is happy; for the brain, together with the spinal cord and nerves which depend upon it, is, as it were, implanted in the organism, and is nourished by it without on its part directly contributing anything to the support of the economy of the organism; therefore there can be life without a brain, as in the case of brainless abortions, and also in the case of tortoises, which live for three weeks after their heads have been cut off; only the medulla oblongata, as the organ of respiration, must be spared. Indeed a hen whose whole brain Flourens had cut away lived for ten months and grew. Even in the case of men the destruction of the brain does not produce death directly, but only through the medium of the lungs, and then of the heart (Bichat, Sur la Vie et la Mort, Part ii., art. ii. § 1). On the other hand, the brain controls the relations to the external world; this alone is its office, and hereby it discharges its debt to the organism which nourishes it, since its existence is conditioned by the external relations. Accordingly the brain alone of all the parts requires sleep, because its activity is completely distinct from its support; the former only consumes both strength and substance, the latter is performed by the rest of the organism as the nurse of the brain: thus because its activity contributes nothing to its continued existence it becomes exhausted, and only when it pauses in sleep does its nourishment go on unhindered.

The second part of our thesis, stated above, will require a fuller exposition even after all that I have said about it in the writings referred to. I have shown above, in chapter 18, that the thing in itself, which must lie at the foundation of every phenomenon, and therefore of our own phenomenal existence also, throws off in self-consciousness one of its phenomenal forms – space, and only retains the other – time. On this account it presents itself here more immediately than anywhere else, and we claim it as will, according to its most undisguised manifestation. But no permanent substance, such as matter is, can present itself in time alone, because, as § 4 of the first volume showed, such a substance is only possible through the intimate union of space and time. Therefore, in self-consciousness the will is not apprehended as the enduring substratum of its impulses, therefore is not perceived as a permanent substance; but only its individual acts, such as purposes, wishes, and emotions, are known successively and during the time they last, directly, yet not perceptibly. The knowledge of the will in self-consciousness is accordingly not a perception of it, but a perfectly direct becoming aware of its successive impulses. On the other hand, for the knowledge which is directed outwardly, brought about by the senses and perfected in the understanding, which, besides time, has also space for its form, which two it connects in the closest manner by means of the function of the understanding, causality, whereby it really becomes perception– this knowledge presents to itself perceptibly what in inner immediate apprehension was conceived as will, as organic body, whose particular movements visibly present to us the acts, and whose parts and forms visibly present to us the sustained efforts, the fundamental character, of the individually given will, nay, whose pain and comfort are perfectly immediate affections of this will itself.

We first become aware of this identity of the body with the will in the individual actions of the two, for in these what is known in self-consciousness as an immediate, real act of will, at the same time and unseparated, exhibits itself outwardly as movement of the body; and every one beholds the purposes of his will, which are instantaneously brought about by motives which just as instantaneously appear at once as faithfully copied in as many actions of his body as his body itself is copied in his shadow; and from this, for the unprejudiced man, the knowledge arises in the simplest manner that his body is merely the outward manifestation of his will, i. e., the way in which his will exhibits itself in his perceiving intellect, or his will itself under the form of the idea. Only if we forcibly deprive ourselves of this primary and simple information can we for a short time marvel at the process of our own bodily action as a miracle, which then rests on the fact that between the act of will and the action of the body there is really no causal connection, for they are directly identical, and their apparent difference only arises from the circumstance that here what is one and the same is apprehended in two different modes of knowledge, the outer and the inner. Actual willing is, in fact, inseparable from doing and in the strictest sense only that is an act of will which the deed sets its seal to. Mere resolves of the will, on the contrary, till they are carried out, are only intentions, and are therefore matter of the intellect alone; as such they have their place merely in the brain, and are nothing more than completed calculations of the relative strength of the different opposing motives. They have, therefore, certainly great probability, but no infallibility. They may turn out false, not only through alteration of the circumstances, but also from the fact that the estimation of the effect of the respective motives upon the will itself was erroneous, which then shows itself, for the deed is untrue to the purpose: therefore before it is carried out no resolve is certain. The will itself, then, is operative only in real action; hence in muscular action, and consequently in irritability. Thus the will proper objectifies itself in this. The cerebrum is the place of motives, where, through these, the will becomes choice, i. e., becomes more definitely determined by motives. These motives are ideas, which, on the occasion of external stimuli of the organs of sense, arise by means of the functions of the brain, and are also worked up into conceptions, and then into resolves. When it comes to the real act of will these motives, the workshop of which is the cerebrum, act through the medium of the cerebellum upon the spinal cord and the motor nerves which proceed from it, which then act upon the muscles, yet merely as stimuli of their irritability; for galvanic, chemical, and even mechanical stimuli can effect the same contraction which the motor nerve calls forth. Thus what was motive in the brain acts, when it reaches the muscle through the nerves, as mere stimulus. Sensibility in itself is quite unable to contract a muscle. This can only be done by the muscle itself, and its capacity for doing so is called irritability, i. e., susceptibility to stimuli. It is exclusively a property of the muscle, as sensibility is exclusively a property of the nerve. The latter indeed gives the muscle the occasion for its contraction, but it is by no means it that, in some mechanical way, draws the muscle together; but this happens simply and solely on account of the irritability, which is a power of the muscle itself. Apprehended from without this is a Qualitas occulta, and only self-consciousness reveals it as the will. In the causal chain here briefly set forth, from the effect of the motive lying outside us to the contraction of the muscle, the will does not in some way come in as the last link of the chain; but it is the metaphysical substratum of the irritability of the muscle: thus it plays here precisely the same part which in a physical or chemical chain of causes is played by the mysterious forces of nature which lie at the foundation of the process – forces which as such are not themselves involved as links in the causal chain, but impart to all the links of it the capacity to act, as I have fully shown in § 26 of the first volume. Therefore we would ascribe the contraction of the muscle also to a similar mysterious force of nature, if it were not that this contraction is disclosed to us by an entirely different source of knowledge – self-consciousness as will. Hence, as was said above, if we start from the will our own muscular movement appears to us a miracle; for indeed there is a strict causal chain from the external motive to the muscular action; but the will itself is not included as a link in it, but, as the metaphysical substratum of the possibility of an action upon the muscle through brain and nerve, lies at the foundation of the present muscular action also; therefore the latter is not properly its effect but its manifestation. As such it enters the world of idea, the form of which is the law of causality, a world which is entirely different from the will in itself: and thus, if we start from the will, this manifestation has, for attentive reflection, the appearance of a miracle, but for deeper investigation it affords the most direct authentication of the great truth that what appears in the phenomenon as body and its action is in itself will. If now perhaps the motor nerve that leads to my hand is severed, the will can no longer move it. This, however, is not because the hand has ceased to be, like every part of my body, the objectivity, the mere visibility, of my will, or in other words, that the irritability has vanished, but because the effect of the motive, in consequence of which alone I can move my hand, cannot reach it and act on its muscles as a stimulus, for the line of connection between it and the brain is broken. Thus really my will is, in this part, only deprived of the effect of the motive. The will objectifies itself directly, in irritability, not in sensibility.
