The Ideas, as we have seen, constitute the determinate stages of objectivation of the Will. The innumerable individuals of which the Ideas are the patterns are subject to the law of sufficient reason. They appear, that is to say, under the forms of time, space, and causality. The Idea is beyond these forms, and therefore is clear of plurality and change. Since the law of sufficient reason is the common form under which stands all the subject's knowledge so far as the subject knows as individual, the Ideas lie outside the sphere of knowledge of the individual as such. If, therefore, the Ideas are to be the object of knowledge, this can only be by annulling individuality in the knowing subject. As thing-in-itself, the Will is exempt even from the first of the forms of knowledge, the form of being 'object for a subject.' The Platonic Idea, on the other hand, is necessarily an object, something known, a presentation. It has laid aside, or rather has not taken on, the subordinate forms; but it has retained the first and most general form. It is the immediate and most adequate possible objectivity of the Will; whereas particular things are an objectivation troubled by the forms of which the law of sufficient reason is the common expression. When intellect breaks loose from the service of the will, for which it was originally destined in the teleology of nature, then the subject ceases to be merely individual and becomes pure will-less subject of knowledge. In this state the beholder no longer tracks out relations in accordance with the principle of sufficient reason--which is the mode of scientific as well as of common knowledge--but rests in fixed contemplation of the given object apart from its connection with anything else. The contemplator thus 'lost' in the object, it is not the single thing as such that is known, but the Idea, the eternal form, the immediate objectivity of the Will at this stage. The correlate of this object--the pure Subject exempt from the principle of sufficient reason--is eternal, like the Idea.
