nence, and excites astonishment. This consideration makes it clear that in all animal natures the will is what is primary and substantial, the intellect again is secondary, adventitious, indeed a mere tool for the service of the former, and is more or less complete and complicated, according to the demands of this service. As a species of animals is furnished with hoofs, claws, hands, wings, horns, or teeth according to the aims of its will, so also is it furnished with a more or less developed brain, whose function is the intelligence necessary for its endurance. The more complicated the organisation becomes, in the ascending series of animals, the more numerous also are its wants, and the more varied and specially determined the objects which are capable of satisfying them; hence the more complicated and distant the paths by which these are to be obtained, which must now be all known and found: there fore in the same proportion the ideas of the animal must be more versatile, accurate, definite, and connected, and also its attention must be more highly strung, more sustained, and more easily roused, consequently its intellect must be more developed and perfect. Accordingly we see the organ of intelligence, the cerebral system, together with all the organs of sense, keep pace with the increasing wants and the complication of the organism; and the increase of the part of consciousness that has to do with ideas (as opposed to the willing part) exhibits itself in a bodily form in the ever-increasing proportion of the brain in general to the rest of the nervous system, and of the cerebrum to the cerebellum; for (according to Flourens) the former is the workshop of ideas, while the latter is the disposer and orderer of movements. The last step which nature has taken in this respect is, however, disproportionately great. For in man not only does the faculty of ideas of perception, which alone existed hitherto, reach the highest degree of perfection, but the abstract idea, thought, i.e., reason, and with it reflection, is added. Through this important advance of the intellect, thus
