Артур Шопенгауэр - The World as Will and Idea (Vol. 3 of 3)

It results from this whole objective consideration of the intellect and its origin, that it is designed for the comprehension of those ends upon the attainment of which depends the individual life and its propagation, but by no means for deciphering the inner nature of things and of the world, which exists independently of the knower. What to the plant is the susceptibility to light, in consequence of which it guides its growth in the direction of it, that is, in kind, the knowledge of the brute, nay, even of man, although in degree it is increased in proportion as the needs of each of these beings demand. With them all apprehension remains a mere consciousness of their relations to other things, and is by no means intended to present again in the consciousness of the knower the peculiar, absolutely real nature of these things. Rather, as springing from the will, the intellect is also only designed for its service, thus for the apprehension of motives; it is adapted for this, and is therefore of a thoroughly practical tendency. This also holds good if we conceive the significance of life as ethical; for in this regard too we find man knowing only for the benefit of his conduct. Such a faculty of knowledge, existing exclusively for practical ends, will from its nature always comprehend only the relations of things to each other, but not the inner nature of them, as it is in itself. But to regard the complex of these relations as the absolute nature of the world as it is in itself, and the manner in which it necessarily exhibits itself in accordance with the laws predisposed in the brain as the eternal laws of the existence of all things, and then to construct ontology, cosmology, and theology in accordance with this view – this was really the old fundamental error, of which Kant's teaching has made an end. Here, then, our objective, and therefore for the most part physiological consideration of the intellect meets his transcendental consideration of it; nay, appears in a certain sense even as an a priori insight into it; for, from a point of view which we have taken up outside of it, our objective view enables us to know in its origin, and therefore as necessary , what that transcendental consideration, starting from facts of consciousness, presents only as a matter of fact. For it follows from our objective consideration of the intellect, that the world as idea, as it exists stretched out in space and time, and moves on regularly according to the strict law of causality, is primarily only a physiological phenomenon, a function of the brain, which brings it about, certainly upon the occasion of certain external stimuli, but yet in conformity with its own laws. Accordingly it is beforehand a matter of course, that what goes on in this function itself, and therefore through it and for it, must by no means be regarded as the nature of things in themselves , which exist independently of it and are entirely different from it, but primarily exhibits only the mode or manner of this function itself, which can always receive only a very subordinate modification through that which exists completely independently of it, and sets it in motion as a stimulus. As, then, Locke claimed for the organs of sense all that comes into our apprehension by means of the sensation, in order to deny that it belongs to things in themselves, so Kant, with the same intention, and pursuing the same path further, has proved all that makes perception proper possible, thus space, time, and causality, to be functions of the brain; although he has refrained from using this physiological expression, to which, however, our present method of investigation, coming from the opposite side, the side of the real, necessarily leads us. Kant arrived upon his analytical path at the result that what we know are mere phenomena . What this mysterious expression really means becomes clear from our objective and genetic investigation of the intellect. The phenomena are the motives for the aims of individual will as they exhibit themselves in the intellect which the will has produced for this purpose (which itself appears as a phenomenon objectively, as the brain), and which, when comprehended, as far as one can follow their concatenation, afford us in their connection the world which extends itself objectively in time and space, and which I call the world as idea. Moreover, from our point of view, the objectionable element vanishes which in the Kantian doctrine arises from the fact that, because the intellect knows merely phenomena instead of things as they are in themselves, nay, in consequence of this is led astray into paralogisms and unfounded hypostases by means of “sophistications, not of men but of the reason itself, from which even the wisest does not free himself, and if, perhaps indeed after much trouble, he avoids error, can yet never get quit of the illusion which unceasingly torments and mocks him” – because of all this, I say, the appearance arises that our intellect is intentionally designed to lead us into errors. For the objective view of the intellect given here, which contains a genesis of it, makes it conceivable that, being exclusively intended for practical ends, it is merely the medium of motives , and therefore fulfils its end by an accurate presentation of these, and that if we undertake to discover the nature of things in themselves, from the manifold phenomena which here exhibit themselves objectively to us, and their laws, we do this at our own peril and on our own responsibility. We have recognised that the original inner force of nature, without knowledge and working in the dark, which, if it has worked its way up to self-consciousness, reveals itself to this as will , attains to this grade only by the production of an animal brain and of knowledge, as its function, whereupon the phenomenon of the world of perception arises in this brain. But to explain this mere brain phenomenon, with the conformity to law which is invariably connected with its functions, as the objective inner nature of the world and the things in it, which is independent of the brain, existing before and after it, is clearly a spring which nothing warrants us in making. From this mundus phœnomenon , however, from this perception which arises under such a variety of conditions, all our conceptions are drawn. They have all their content from it, or even only in relation to it. Therefore, as Kant says, they are only for immanent, not for transcendental, use; that is to say, these conceptions of ours, this first material of thought, and consequently still more the judgments which result from their combination, are unfitted for the task of thinking the nature of things in themselves, and the true connection of the world and existence; indeed, to undertake this is analogous to expressing the stereometrical content of a body in square inches. For our intellect, originally only intended to present to an individual will its paltry aims, comprehends accordingly mere relations of things, and does not penetrate to their inner being, to their real nature. It is therefore a merely superficial force, clings to the surface of things, and apprehends mere species transitivas , not the true being of things. From this it arises that we cannot understand and comprehend any single thing, even the simplest and smallest, through and through, but something remains entirely inexplicable to us in each of them. Just because the intellect is a product of nature, and is therefore only intended for its ends, the Christian mystics have very aptly called it “the light of nature,” and driven it back within its limits; for nature is the object to which alone it is the subject. The thought from which the Critique of Pure Reason has sprung really lies already at the foundation of this expression. That we cannot comprehend the world on the direct path, i. e. , through the uncritical, direct application of the intellect and its data, but when we reflect upon it become ever more deeply involved in insoluble mysteries, points to the fact that the intellect, thus knowledge itself, is secondary, a mere product, brought about by the development of the inner being of the world, which consequently till then preceded it, and it at last appeared as a breaking through to the light out of the obscure depths of the unconscious striving the nature of which exhibits itself as will to the self-consciousness which now at once arises. That which preceded knowledge as its condition, whereby it first became possible, thus its own basis, cannot be directly comprehended by it; as the eye cannot see itself. It is rather the relations of one existence to another, exhibiting themselves upon the surface of things, which alone are its affair, and are so only by means of the apparatus of the intellect, its forms, space, time, and causality. Just because the world has made itself without the assistance of knowledge, its whole being does not enter into knowledge, but knowledge presupposes the existence of the world; on which account the origin of the world does not lie within its sphere. It is accordingly limited to the relations between the things which lie before it, and is thus sufficient for the individual will, for the service of which alone it appeared. For the intellect is, as has been shown, conditioned by nature, lies in it, belongs to it, and cannot therefore place itself over against it as something quite foreign to it, in order thus to take up into itself its whole nature, absolutely, objectively, and thoroughly. It can, if fortune favours it, understand all that is in nature, but not nature itself, at least not directly.
