3. _Nature in a strict sense_, the scene of elemental working, represents to us a constant and progressive transition of the elementary to the vegetative, and of the vegetative to the animal world. The lowest step is occupied by the inanimate bodies of nature, which are simple products of the elements mingling themselves together, and have their entelechy only in the determinate combinations of these elements, but whose energy consists only in striving after a fitting place in the universe, and in resting there so far as they reach it unhindered. But now such a mere external entelechy is not possessed by the living bodies; within them dwells a motion as organizing principle by which they attain to actuality, and which as a preserving activity develops in them towards a perfected organization,—in a word they have a soul, for a soul is the entelechy of an organic body. In plants we find the soul working only as persevering and nourishing energy: the plant has no other function than to nourish itself and to propagate its kind; among animals—where we find a progress according to the mode of their reproduction—the soul appears as sensitive; animals have sense, and are capable of locomotion; lastly, the human soul is at the same time nutritive, sensitive, and cognitive. 4. _Man_, as the end of all nature, embraces in himself the different steps of development in which the life of nature is exhibited. The division of the faculties of the soul must therefore be necessarily regulated, according to the division of living creatures. As the nutritive faculty is alone the property of vegetables, and sensation, of animals, while to the more perfect animals locomotion also belongs, so are these three activities also development steps of the human soul, the antecedent being the necessary condition of, and presupposed in time by, the subsequent, while the soul itself is nothing other than the union of these different activities of an organic body in one common end, as the entelechy of the organic body. The fourth step, thought or reason, which, added to the three others, constitutes the peculiarity of the human soul, forms alone an exception from the general law. It is not a simple product of the lower facilities of the soul, it does not stand related to them simply as a higher stage of development, nor simply as the soul to the body, as the end to the instrument, as actuality to possibility, as form to matter. But as pure intellectual activity, it completes itself without any mediation of a bodily organ; as the reason comes into the body from without, so is it separable from the body, and therefore has it no inner connection with the bodily functions, but is something wholly foreign in nature. True, there exists a connection between thought and sensation, for while the sensations are outwardly divided, according to the different objects of sense, yet internally they meet in one centre, as a common sense. Here they become changed
