VII. (28) Having therefore gone through all the larger plants in the universe, let us see in what manner the all-wise God made the trees which exist in the smaller world, that is to say, in man. In the first place, then, taking our body as if it were a field of deep soil, he created the external senses to be in it as so many channels. (29) And after that, he arranged the place of each separate one of them, as if it had been a fruit-bearing and most useful tree, assigning the sense of hearing to the ear, that of sight to the eyes, that of smell to the nostrils, and each of the other senses and faculties to their kindred and appropriate organs. And the divine man bears his testimony to this account of mine, speaking thus in his Psalms, “He that planted the ear, doth he not hear? and he that made the eyes, shall he not See?”{8}{psalm 94:9.} (30) Moreover, all the different powers which run down as far as the legs and hands, and all the other parts of the body, whether internal or external, are all those of an unimportant kind. (31) But those which are better and more perfect he has rooted in the more central portion; that which is pre-eminently able to bring forth fruit, the dominant portion of the man. These faculties are perception, comprehension, felicity of conjecture, study, memory, habit, disposition, the various species of art, the firmness of knowledge of different things, the apprehension of the speculations of universal virtue in such a way as is never forgotten. Now, no mortal is competent to plant any one of these things himself. But of all of them together there is one architect, the uncreated God, who has not only made them originally, but who also makes them for and implants them in every individual man that is born.
