Is it not also true that no physician, in so far as he is a physician, considers or enjoins what is for the physician's interest, but that all seek the good of their patients? For we have agreed that a physician strictly so called, is a ruler of bodies, and not a maker of money, have we not?
PlatoEither we shall find what it is we are seeking or at least we shall free ourselves from the persuasion that we know what we do not know.
