“Pflanzenphysiologie” (p. 68-72 of the second, and 74-77 of the third edition), to which I refer, in order to avoid repetition, and merely add here a few remarks. Since the plant possesses neither irritability nor sensibility, but the will objectifies itself in it only as plastic or reproductive power, it has neither muscle nor nerve. In the lowest grades of the animal kingdom, in zoophites, especially in polyps, we cannot as yet distinctly recognise the separation of these two constituent parts, but still we assume their existence, though in a state of fusion; because we perceive movements which follow, not, as in the case of plants, upon mere stimuli, but upon motives, i. e., in consequence of a certain apprehension. Now in proportion as, in the ascending series of animals, the nervous and muscular systems separate ever more distinctly from each other, till in the vertebrate animals, and most completely in man, the former divides into an organic and a cerebral nervous system, and of these the latter again develops into the excessively complicated apparatus of the cerebrum and cerebellum, spinal marrow, cerebral and spinal nerves, sensory and motor nerve fascicles, of which only the cerebrum, together with the sensory nerves depending upon it, and the posterior spinal nerve fascicles are intended for the apprehension of the motive from the external world, while all the other parts are intended for the transmission of the motive to the muscles in which the will manifests itself directly; in the same proportion does the motive separate ever more distinctly in consciousness from the act of will which it calls forth, thus the idea from the will; and thereby the objectivity of consciousness constantly increases, for the ideas exhibit themselves ever more distinctly and purely in it. These two separations are, however, really only one and the same, which we have here considered from two sides, the objective and the subjective, or first in the consciousness of other things and then in self-consciousness. Upon the degree of this separation ultimately depends the difference and the gradation of intellectual capacity, both between different kinds of animals and between individual human beings; thus it gives the standard for the intellectual completeness of these beings. For the clearness of the consciousness of the external world, the objectivity of the perception, depends upon it. In the passage referred to above I have shown that the brute only perceives things so far as they are motives for its will, and that even the most intelligent of the brutes scarcely overstep these limits, because their intellect is too closely joined to the will from which it has sprung. On the other hand, even the stupidest man comprehends things in some degree objectively; for he recognises not merely what they are with reference to him, but also something of what they are with reference to themselves and to other things. Yet in the case of very few does this reach such a degree that they are in a position to examine and judge of anything purely objectively; but “that must I do, that must I say, that must I believe,” is the goal to which on every occasion their thought hastens in a direct line, and at which their understanding at once finds welcome rest. For thinking is as unendurable to the weak head as the lifting of a burden to the weak arm; therefore both hasten to set it down. The objectivity of knowledge, and primarily of perceptive knowledge, has innumerable grades, which depend upon the energy of the intellect and its separation from the will, and the highest of which is genius, in which the comprehension of the external world becomes so pure and objective that to it even more reveals itself directly in the individual thing than the individual thing itself, namely, the nature of its whole species, i. e., its Platonic Idea; which is brought about by the fact that in this case the will entirely vanishes from consciousness. Here is the point at which the present investigation, starting from physiological grounds, connects itself with the subject of our third book, the metaphysics of the beautiful, where æsthetic comprehension proper, which, in a high degree, is peculiar to genius alone, is fully considered as the condition of pure, i. e., perfectly will-less, and on that account completely objective knowledge. According to what has been said, the rise of intelligence, from the obscurest animal consciousness up to that of man, is a progressive loosening of the intellect from the will, which appears complete, although only as an exception, in the genius. Therefore genius may be defined as the highest grade of the objectivity of knowledge. The condition of this, which so seldom occurs, is a decidedly larger measure of intelligence than is required for the service of the will, which constitutes its basis; it is accordingly this free surplus which first really properly comes to know the world, i. e., comprehends it perfectly objectively, and now paints pictures, composes poems, and thinks in accordance with this comprehension.
Chapter XXIII.3On The Objectification Of The Will In Unconscious Nature
That the will which we find within us does not proceed, as philosophy has hitherto assumed, first from knowledge, and indeed is a mere modification of it, thus something secondary, derived, and, like knowledge itself, conditioned by the brain; but that it is the prius of knowledge, the kernel of our nature, and that original force itself which forms and sustains the animal body, in that it carries out both its unconscious and its conscious functions; – this is the first step in the fundamental knowledge of my metaphysics. Paradoxical as it even now seems to many that the will in itself is without knowledge, yet the scholastics in some way already recognised and confessed it; for Jul. Cæs. Vaninus (that well-known sacrifice to fanaticism and priestly fury), who was thoroughly versed in their philosophy, says in his “Amphitheatro,” p. 181: “Voluntas potentia cœca est, ex scholasticorum opinione.” That, further, it is that same will which in the plant forms the bud in order to develop the leaf and the flower out of it; nay, that the regular form of the crystal is only the trace which its momentary effort has left behind, and that in general, as the true and only αυτοματον, in the proper sense of the word, it lies at the foundation of all the forces of unorganised nature, plays, acts, in all their multifarious phenomena, imparts power to their laws, and even in the crudest mass manifests itself as gravity; – this insight is the second step in that fundamental knowledge, and is brought about by further reflection. But it would be the grossest misunderstanding to suppose that this is a mere question of a word to denote an unknown quantity. It is rather the most real of all real knowledge which is here expressed in language. For it is the tracing back of that which is quite inaccessible to our immediate knowledge, and therefore in its essence foreign and unknown to us, which we denote by the words force of nature, to that which is known to us most accurately and intimately, but which is yet only accessible to us in our own being and directly, and must therefore be carried over from this to other phenomena. It is the insight that what is inward and original in all the changes and movements of bodies, however various they may be, is in its nature identical; that yet we have only one opportunity of getting to know it more closely and directly, and that is in the movements of our own body. In consequence of this knowledge we must call it will. It is the insight that that which acts and strives in nature, and exhibits itself in ever more perfect phenomena, when it has worked itself up so far that the light of knowledge falls directly upon it, i. e., when it has attained to the state of self-consciousness – exists as that will, which is what is most intimately known to us, and therefore cannot be further explained by anything else, but rather affords the explanation of all other things. It is accordingly the thing in itself so far as this can ever be reached by knowledge. Consequently it is that which must express itself in some way in everything in the world, for it is the inner nature of the world and the kernel of all phenomena.
As my essay, “Ueber den Willen in der Natur,” specially refers to the subject of this chapter, and also adduces the evidence of unprejudiced empiricists in favour of this important point of my doctrine, I have only to add now to what is said there a few supplementary remarks, which are therefore strung together in a somewhat fragmentary manner.
First, then, with reference to plant life, I draw attention to the remarkable first two chapters of Aristotle's work upon plants. What is most interesting in them, as is so often the case with Aristotle, are the opinions of earlier profound philosophers quoted by him. We see there that Anaxagoras and Empedocles quite rightly taught that plants have the motion of their growth by virtue of their indwelling desires (επιθυμια); nay, that they also attributed to them pleasure and pain, therefore sensation. But Plato only ascribed to them desires, and that on account of their strong appetite for nutrition (cf.
This chapter is connected with § 23 of the first volume.
