In fact, freedom from all aim, from all limits, belongs to the nature of the will, which is an endless striving. This was already touched on above in the reference to centrifugal force. It also discloses itself in its simplest form in the lowest grade of the objectification of will, in gravitation, which we see constantly exerting itself, though a final goal is obviously impossible for it. For if, according to its will, all existing matter were collected in one mass, yet within this mass gravity, ever striving towards the centre, would still wage war with impenetrability as rigidity or elasticity. The tendency of matter can therefore only be confined, never completed or appeased. But this is precisely the case with all tendencies of all phenomena of will. Every attained end is also the beginning of a new course, and so on ad infinitum. The plant raises its manifestation from the seed through the stem and the leaf to the blossom and the fruit, which again is the beginning of a new seed, a new individual, that runs through the old course, and so on through endless time. Such also is the life of the animal; procreation is its highest point, and after attaining to it, the life of the first individual quickly or slowly sinks, while a new life ensures to nature the endurance of the species and repeats the same phenomena. Indeed, the constant renewal of the matter of every organism is also to be regarded as merely the manifestation of this continual pressure and change, and physiologists are now ceasing to hold that it is the necessary reparation of the matter wasted in motion, for the possible wearing out of the machine can by no means be equivalent to the support it is constantly receiving through nourishment. Eternal becoming, endless flux, characterises the revelation of the inner nature of will. Finally, the same thing shows itself in human endeavours and desires, which always delude us by presenting their satisfaction as the final end of will. As soon as we attain to them they no longer appear the same, and therefore they soon grow stale, are forgotten, and though not openly disowned, are yet always thrown aside as vanished illusions. We are fortunate enough if there still remains something to wish for and to strive after, that the game may be kept up of constant transition from desire to satisfaction, and from satisfaction to a new desire, the rapid course of which is called happiness, and the slow course sorrow, and does not sink into that stagnation that shows itself in fearful ennui that paralyses life, vain yearning without a definite object, deadening languor. According to all this, when the will is enlightened by knowledge, it always knows what it wills now and here, never what it wills in general; every particular act of will has its end, the whole will has none; just as every particular phenomenon of nature is determined by a sufficient cause so far as concerns its appearance in this place at this time, but the force which manifests itself in it has no general cause, for it belongs to the thing-in-itself, to the groundless will. The single example of self-knowledge of the will as a whole is the idea as a whole, the whole world of perception. It is the objectification, the revelation, the mirror of the will. What the will expresses in it will be the subject of our further consideration.43

Τί τὸ ὄν μὲν ἀεί, γένεσιν δὲ οὐκ ἔχον; καὶ τί τό γιγνόμενον μὲν καὶ ἀπολλύμενον, ὄντως δε οὐδέποτε ὄν.——ΠΛΑΤΩΝ.
§ 30. In the First Book the world was explained as mere idea, object for a subject. In the Second Book we considered it from its other side, and found that in this aspect it is will, which proved to be simply that which this world is besides being idea. In accordance with this knowledge we called the world as idea, both as a whole and in its parts, the objectification of will, which therefore means the will become object, i.e., idea. Further, we remember that this objectification of will was found to have many definite grades, in which, with gradually increasing distinctness and completeness, the nature of will appears in the idea, that is to say, presents itself as object. In these grades we already recognised the Platonic Ideas, for the grades are just the determined species, or the original unchanging forms and qualities of all natural bodies, both organised and unorganised, and also the general forces which reveal themselves according to natural laws. These Ideas, then, as a whole express themselves in innumerable individuals and particulars, and are related to these as archetypes to their copies. The multiplicity of such individuals is only conceivable through time and space, their appearing and passing away through causality, and in all these forms we recognise merely the different modes of the principle of sufficient reason, which is the ultimate principle of all that is finite, of all individual existence, and the universal form of the idea as it appears in the knowledge of the individual as such. The Platonic Idea, on the other hand, does not come under this principle, and has therefore neither multiplicity nor change. While the individuals in which it expresses itself are innumerable, and unceasingly come into being and pass away, it remains unchanged as one and the same, and the principle of sufficient reason has for it no meaning. As, however, this is the form under which all knowledge of the subject comes, so far as the subject knows as an individual, the Ideas lie quite outside the sphere of its knowledge. If, therefore, the Ideas are to become objects of knowledge, this can only happen by transcending the individuality of the knowing subject. The more exact and detailed explanation of this is what will now occupy our attention.
§ 31. First, however, the following very essential remark. I hope that in the preceding book I have succeeded in producing the conviction that what is called in the Kantian philosophy the thing-in-itself, and appears there as so significant, and yet so obscure and paradoxical a doctrine, and especially on account of the manner in which Kant introduced it as an inference from the caused to the cause, was considered a stumbling-stone, and, in fact, the weak side of his philosophy—that this, I say, if it is reached by the entirely different way by which we have arrived at it, is nothing but the will when the sphere of that conception is extended and defined in the way I have shown. I hope, further, that after what has been said there will be no hesitation in recognising the definite grades of the objectification of the will, which is the inner reality of the world, to be what Plato called the eternal Ideas or unchangeable forms (ειδῆ); a doctrine which is regarded as the principal, but at the same time the most obscure and paradoxical dogma of his system, and has been the subject of reflection and controversy of ridicule and of reverence to so many and such differently endowed minds in the course of many centuries.
If now the will is for us the thing-in-itself, and the Idea is the immediate objectivity of that will at a definite grade, we find that Kant's thing-in-itself, and Plato's Idea, which to him is the only οντως ον, these two great obscure paradoxes of the two greatest philosophers of the West are not indeed identical, but yet very closely related, and only distinguished by a single circumstance. The purport of these two great paradoxes, with all inner harmony and relationship, is yet so very different on account of the remarkable diversity of the individuality of their authors, that they are the best commentary on each other, for they are like two entirely different roads that conduct us to the same goal. This is easily made clear. What Kant says is in substance this:—“Time, space, and causality are not determinations of the thing-in-itself, but belong only to its phenomenal existence, for they are nothing but the forms of our knowledge. Since, however, all multiplicity, and all coming into being and passing away, are only possible through time, space, and causality, it follows that they also belong only to the phenomenon, not to the thing-in-itself. But as our knowledge is conditioned by these forms, the whole of experience is only knowledge of the phenomenon, not of the thing-in-itself; therefore its laws cannot be made valid for the thing-in-itself. This extends even to our own ego, and we know it only
