In my treatment of the art of discourse, I desire, like the genealogists, to start at the beginning.Literally, I desire first to discuss the art of discourse after the manner of the genealogists. It is acknowledged that the nature of man is compounded of two parts, the physical and the mental, and no one would deny that of these two the mind comes first and is of greater worth; for it is the function of the mind to decide both on personal and on public questions, and of the body to be servant to the judgements of the mind.

Since this is so, certain of our ancestors, long before our time, seeing that many arts had been devised for other things, while none had been prescribed for the body and for the mind, invented and bequeathed to us two disciplines, physical training for the body, of which gymnastics is a part, and, for the mind, philosophy, which I am going to explain.

These are twin arts—parallel and complementary—by which their masters prepare the mind to become more intelligent and the body to become more serviceable, not separating sharply the two kinds of education, but using similar methods of instruction, exercise, and other forms of discipline.
