Enough of the composite animal, and of the body which is a part of him, and of
the manner in which a man may train and be trained by himself so as to live
most according to reason: and we must above and before all provide that the
element which is to train him shall be the fairest and best adapted to that
purpose. A minute discussion of this subject would be a serious task; but if,
as before, I am to give only an outline, the subject may not unfitly be summed
up as follows.
I have often remarked that there are three kinds of soul located within us,
having each of them motions, and I must now repeat in the fewest words
possible, that one part, if remaining inactive and ceasing from its natural
motion, must necessarily become very weak, but that which is trained and
exercised, very strong. Wherefore we should take care that the movements of
the different parts of the soul should be in due proportion.
