The intellect is, according to its destination, merely the medium of motives; and in accordance with this it originally comprehends nothing in things but their relations to the will, the direct, the indirect, and the possible. In the case of the brutes, where it is almost entirely confined to the direct relations, the matter is just on that account most apparent: what has no relation to their will does not exist for them. Therefore we sometimes see with surprise that even clever animals do not observe at all something conspicuous to them; for example, they show no surprise at obvious alterations in our person and surroundings. In the case of normal men the indirect, and even the possible, relations to the will are added, the sum of which make up the total of useful knowledge; but here also knowledge remains confined to the relations. Therefore the normal mind does not attain to an absolutely pure, objective picture of things, because its power of perception, whenever it is not spurred on by the will and set in motion, at once becomes tired and inactive, because it has not enough energy of its own elasticity and without an end in view to apprehend the world in a purely objective manner. Where, on the other hand, this takes place – where the brain has such a surplus of the power of ideation that a pure, distinct, objective image of the external world exhibits itself without any aim; an image which is useless for the intentions of the will, indeed, in the higher degrees, disturbing, and even injurious to them – there, the natural disposition, at least, is already present for that abnormity which the name genius denotes, which signifies that here a genius foreign to the will, i.e., to the I proper, as it were coming from without, seems to be active. But to speak without a figure: genius consists in this, that the knowing faculty has received a considerably greater development than the service of the will, for which alone it originally appeared, demands. Therefore, strictly speaking, physiology might to a certain extent class such a superfluity of brain activity, and with it of brain itself, among the monstra per exces-
