The World as Will and Idea: Complete One Volume Edition. Arthur Schopenhauer

of the phenomenon to the thing-in-itself. Plato, on the other hand, did not attain to the fullest expression, and has only distinctly refused these forms to his Ideas in that he denies of the Ideas what is only possible through these forms, multiplicity of similar things, coming into being and passing away. Though it is perhaps superfluous, I should like to illustrate this remarkable and important agreement by an example. There stands before us, let us suppose, an animal in the full activity of life. Plato would say, “This animal has no true existence, but merely an apparent existence, a constant becoming, a relative existence which may just as well be called non-being as being. Only the Idea which expresses itself in that animal is truly ‘being,’ or the animal in-itself (αυτο το θηριον), which is dependent upon nothing, but is in and for itself (καθ᾽ ἑαυτο, αει ὡς αυτως); it has not become, it will not end, but always is in the same way (αει ον, και μηδεποτε ουτε γυγνομενον ουτε απολλυμενον). If now we recognise its Idea in this animal, it is all one and of no importance whether we have this animal now before us or its progenitor of a thousand years ago, whether it is here or in a distant land, whether it presents itself in this or that manner, position, or action; whether, lastly, it is this or any other individual of the same species; all this is nothing, and only concerns the phenomenon; the Idea of the animal alone has true being, and is the object of real knowledge.” So Plato; Kant would say something of this kind, “This animal is a phenomenon in time, space, and causality, which are collectively the conditions a priori of the possibility of experience, lying in our faculty of knowledge, not determinations of the thing-in-itself. Therefore this animal as we perceive it at this definite point of time, in this particular place, as an individual in the connection of experience (i.e., in the chain of causes and effects), which has come into being, and will just as necessarily pass away, is not a thing-in-itself, but a phenomenon which only exists in relation to our knowledge. To know it as what it may be in itself, that is to say, independent of all the determinations which lie in time, space, and causality, would demand another kind of knowledge than that which is possible for us through the senses and the understanding.”

      In order to bring Kant’s mode of expression nearer the Platonic, we might say: Time, space, and causality are that arrangement of our intellect by virtue of which the one being of each kind which alone really is, manifests itself to us as a multiplicity of similar beings, constantly appearing and disappearing in endless succession. The apprehension of things by means of and in accordance with this arrangement is immanent knowledge; that, on the other hand, which is conscious of the true state of the case, is transcendental knowledge. The latter is obtained in abstracto through the criticism of pure reason, but in exceptional cases it may also appear intuitively. This last is an addition of my own, which I am endeavouring in this Third Book to explain.

      If the doctrine of Kant had ever been properly understood and grasped, and since Kant’s time that of Plato, if men had truly and earnestly reflected on the inner meaning and content of the teaching of these two great masters, instead of involving themselves in the technicalities of the one and writing parodies of the style of the other, they could not have failed to discern long ago to what an extent these two great philosophers agree, and that the true meaning, the aim of both systems, is the same. Not only would they have refrained from constantly comparing Plato to Leibnitz, on whom his spirit certainly did not rest, or indeed to a well-known gentleman who is still alive,{44} as if they wanted to mock the manes of the great thinker of the past; but they would have advanced much farther in general, or rather they would not have fallen so disgracefully far behind as they have in the last forty years. They would not have let themselves be led by the nose, to-day by one vain boaster and to-morrow by another, nor would they have opened the nineteenth century, which promised so much in Germany, with the philosophical farces that were performed over the grave of Kant (as the ancients sometimes did at the funeral obsequies of their dead), and which deservedly called forth the derision of other nations, for such things least become the earnest and strait-laced German. But so small is the chosen public of true philosophers, that even students who understand are but scantily brought them by the centuries—Εισι δη ναρθηκοφοροι μεν πολλοι, βακχοι δε γε παυροι (Thyrsigeri quidem multi, Baachi vero pauci). Ἡ ατιμια φιλοσοφιᾳ δια ταυτα προσπεπτωκεν, ὁτι ου κατ αξιαν αυτης ἁπτονται; ου γαρ νοθους εδει ἁπτεσθαι, αλλα γνησιους (Eam ob rem philosophia in infamiam incidit, quad non pro dignitate ipsam attingunt: neque enim a spuriis, sad a legitimis erat attrectanda).—Plato.

      Men followed the words,—such words as “a priori ideas,” “forms of perception and thought existing in consciousness independently of experience,” “fundamental conceptions of the pure understanding,” &c., &c.,—and asked whether Plato’s Ideas, which were also original conceptions, and besides this were supposed to be reminiscences of a perception before life of the truly real things, were in some way the same as Kant’s forms of perception and thought, which lie a priori in our consciousness. On account of some slight resemblance in the expression of these two entirely different doctrines, the Kantian doctrine of the forms which limit the knowledge of the individual to the phenomenon, and the Platonic doctrine of Ideas, the knowledge of which these very forms expressly deny, these so far diametrically opposed doctrines were carefully compared, and men deliberated and disputed as to whether they were identical, found at last that they were not the same, and concluded that Plato’s doctrine of Ideas and Kant’s “Critique of Reason” had nothing in common. But enough of this.{45}

      § 32. It follows from our consideration of the subject, that, for us, Idea and thing-in-itself are not entirely one and the same, in spite of the inner agreement between Kant and Plato, and the identity of the aim they had before them, or the conception of the world which roused them and led them to philosophise. The Idea is for us rather the direct, and therefore adequate, objectivity of the thing-in-itself, which is, however, itself the will—the will as not yet objectified, not yet become idea. For the thing-in-itself must, even according to Kant, be free from all the forms connected with knowing as such; and it is merely an error on his part (as is shown in the Appendix) that he did not count among these forms, before all others, that of being object for a subject, for it is the first and most universal form of all phenomena, i.e., of all idea; he should therefore have distinctly denied objective existence to his thing-in-itself, which would have saved him from a great inconsistency that was soon discovered. The Platonic Idea, on the other hand, is necessarily object, something known, an idea, and in that respect is different from the thing-in-itself, but in that respect only. It has merely laid aside the subordinate forms of the phenomenon, all of which we include in the principle of sufficient reason, or rather it has not yet assumed them; but it has retained the first and most universal form, that of the idea in general, the form of being object for a subject. It is the forms which are subordinate to this (whose general expression is the principle of sufficient reason) that multiply the Idea in particular transitory individuals, whose number is a matter of complete indifference to the Idea. The principle of sufficient reason is thus again the form into which the Idea enters when it appears in the knowledge of the subject as individual. The particular thing that manifests itself in accordance with the principle of sufficient reason is thus only an indirect objectification of the thing-in-itself (which is the will), for between it and the thing-in-itself stands the Idea as the only direct objectivity of the will, because it has assumed none of the special forms of knowledge as such, except that of the idea in general, i.e., the form of being object for a subject. Therefore it alone is the most adequate objectivity of the will or thing-in-itself which is possible; indeed it is the whole thing-in-itself, only under the form of the idea; and here lies the ground of the great agreement between Plato and Kant, although, in strict accuracy, that of which they speak is not the same. But the particular things are no really adequate objectivity of the will, for in them it is obscured by those forms whose general expression is the principle of sufficient reason, but which are conditions of the knowledge which belongs to the individual as such. If it is allowable to draw conclusions from an impossible presupposition, we would, in fact, no longer know particular things, nor events, nor change, nor multiplicity, but would comprehend only Ideas,—only the grades of the objectification of that one
