Enough, I said, of these civilities. It will be better that I should ask you a question: Is the physician, taken in that strict sense of which you are speaking, a healer of the sick or a maker of money? And remember that I am now speaking of the true physician. . .
Then medicine does not consider the interest of medicine, but the interest of the body?
Then, I continued, no physician, in so far as he is a physician, considers his own good in what he prescribes, but the good of his patient; for the true physician is also a ruler having the human body as a subject, and is not a mere money-maker; that has been admitted?
