the cerebrum, together with the sensory nerves depending upon it, and the posterior spinal nerve fascicles are intended for the apprehension of the motive from the external world, while all the other parts are intended for the transmission of the motive to the muscles in which the will manifests itself directly; in the same proportion does the motive separate ever more distinctly in consciousness from the act of will which it calls forth, thus the idea from the will; and thereby the objectivity of consciousness constantly increases, for the ideas exhibit themselves ever more distinctly and purely in it. These two separations are, however, really only one and the same, which we have here considered from two sides, the objective and the subjective, or first in the consciousness of other things and then in self-consciousness. Upon the degree of this separation ultimately depends the difference and the gradation of intellectual capacity, both between different kinds of animals and between individual human beings; thus it gives the standard for the intellectual completeness of these beings. For the clearness of the consciousness of the external world, the objectivity of the perception, depends upon it. In the passage referred to above I have shown that the brute only perceives things so far as they are motives for its will, and that even the most intelligent of the brutes scarcely overstep these limits, because their intellect is too closely joined to the will from which it has sprung. On the other hand, even the stupidest man comprehends things in some degree objectively; for he recognises not merely what they are with reference to him, but also something of what they are with reference to themselves and to other things. Yet in the case of very few does this reach such a degree that they are in a position to examine and judge of anything purely objectively; but "that must I do, that must I say, that must I believe," is the goal to which on every occasion their thought hastens in a direct line, and at which their understanding at once finds welcome rest. For thinking is as unendurable to
