The objectivation of the Will appears faintly in inorganic things,--clouds, water, crystals,--more fully in the plant, yet more fully in the animal, most completely in man. Only the essential in these stages of objectivation constitutes the Idea. Its development into manifold phenomena under the forms of the principle of sufficient reason, is unessential, lies merely in the mode of knowledge for the individual, and has reality only for this. It is not otherwise with the unfolding of that Idea which is the completest objectivation of the Will. To the Idea of Man, the occurrences of human history are as unessential as the shapes they assume to the clouds, as the figures of its whirlpools and foam-drift to the stream, as its frost-flowers to the ice. The same underlying passions and dispositions everlastingly recur in the same modes. It is idle to suppose that anything is gained. But also nothing is lost: so the Earth-spirit might reply to one who complained of high endeavours frustrated, faculties wasted, promises of world-enlightenment brought to nought; for there is infinite time to dispose of, and all possibilities are for ever renewed. The kind of knowledge for which the Ideas are the object of contemplation finds its expression in Art, the work of genius. Art repeats in its various media the Ideas grasped by pure contemplation. Its only end is the communication of these. While Science, following the stream of events according to their determinate relations, never reaches an ultimate end, Art is always at the end. 'It stops the wheel of time; relations vanish for it: only the essence, the Idea, is its object.' The characteristic of genius is a predominant capacity for thus contemplating things independently of the principle of sufficient reason. Since this requires a forgetting of one's own person and the relations between it and things, the attitude of genius is simply the completest 'objectivity.' The 'subjectivity' opposed to this, in Schopenhauer's phraseology, is preoccupation with the interests of one's own will. It is, he says, as if there fell to the share of genius a measure of intelligence far beyond the needs of the individual will: and this makes possible the setting aside of individual interests, the stripping off of the particular personality, so that the subject becomes 'pure knowing subject,' 'clear world-eye,' in a manner sufficiently sustained for that which has been grasped to be repeated in the work of art. A necessary element in genius is therefore Imagination. For without imagination to represent, in a shape not merely abstract, things that have not come within personal experience, genius would remain limited to immediate intuition, and could not make its vision apprehensible by others. Nor without imagination could the particular things that express the Idea be cleared of the imperfections by which their limited expression of it falls short of what nature was aiming at in their production.
