which it abounded. To him, as to the early poets and sages, Sôphrosynê, or self-knowledge and self-command taken together, was the first and most necessary of all virtues. Unlike them, however, he does not simply accept it from tradition, but gives it a philosophical foundation—the newly-established distinction between mind and body; a distinction not to be confounded with the old Psychism, although Plato, for his reforming purposes, shortly afterwards linked the two together. The disembodied spirit of mythology was a mere shadow or memory, equally destitute of solidity and of understanding; with Socrates, mind meant the personal consciousness which retains its continuous identity through every change, and as against every passing impulse. Like the Humanists, he made it the seat of knowledge—more than the Humanists, he gave it the control of appetite. In other words, he adds the idea of will to that of intellect; but instead of treating them as distinct faculties or functions, he absolutely identifies them. Mind having come to be first recognised as a knowing power, carried over its association with knowledge into the volitional sphere, and the two were first disentangled by Aristotle, though very imperfectly even by him. Yet no thinker helped so much to make the confusion apparent as the one to whom it was due. Socrates deliberately insisted that those who knew the good must necessarily be good themselves. He taught that every virtue was a science; courage, for example, was a knowledge of the things which should or should not be feared; temperance, a knowledge of what should or should not be desired, and so forth. Such an account of virtue would, perhaps, be sufficient if all men did what, in their opinion, they ought to do; and, however strange it may seem, Socrates assumed that such was actually the case.[89] The paradox, even if accepted at the moment by his youthful friends, was sure to be rejected, on examination, by cooler heads, and its rejection would prove that the whole doctrine was essentially unsound. Various causes prevented Socrates from perceiving what seemed so clear to duller intelligences than his. First of all, he did not separate duty from personal interest. A true Athenian, he recommended temperance and righteousness very largely on account of the material advantages they secured. That the agreeable and the honourable, the expedient and the just, frequently came into collision, was at that time a rhetorical commonplace; and it might be supposed that, if they were shown to coincide, no motive to misconduct but ignorance could exist. Then, again, being accustomed to compare conduct of every kind with the practice of such arts as flute-playing, he had come to take knowledge in a rather extended sense, just as we do when we say, indifferently, that a man knows geometry and that he knows how to draw. Aristotle himself did not see more clearly than Socrates that moral habits are
