3. If we run through the series of grades of animals downwards, we see the intellect always becoming weaker and less perfect, but we by no means observe a corresponding degradation of the will. Rather it retains everywhere its identical nature and shows itself in the form of great attachment to life, cave for the individual and the species, egoism and regardlessness of all others, together with the emotions that spring from these. Even in the smallest insect the will is present, complete and entire; it wills what it wills as decidedly and completely as the man. The difference lies merely in what it wills, i.e., in the motives, which, however, are the affair of the intellect. It indeed, as the secondary part of consciousness, and bound to the bodily organism, has innumerable degrees of completeness, and is in general essentially limited and imperfect. The will, on the contrary, as original and the thing in itself, can never be imperfect, but every act of will is all that it can be. On account of the simplicity which belongs to the will as the thing in itself, the metaphysical in the phenomenon, its nature admits of no degrees, but is always completely itself. Only its excitement has degrees, from the weakest inclination to the passion, and also its susceptibility to excitement, thus its vehemence from the phlegmatic to the choleric temperament. The intellect, on the other hand, has not merely degrees of excitement, from sleepiness to being in the vein, and inspiration, but also degrees of its nature, of the completeness of this, which accordingly rises gradually from the lowest animals, which can only obscurely apprehend, up to man, and here again from the fool to the genius. The will alone is everywhere completely itself. For its function is of the utmost simplicity; it consists in willing and not willing, which goes on with the greatest ease, without effort, and requires no practice. Knowing, on the contrary, has multifarious functions, and never takes place entirely without effort, which is required to fix the attention and to make clear the object, and at a higher
