SOCRATES: But then, my dear friend, if a man knew all good and evil, and how they are, and have been, and will be produced, would he not be perfect, and wanting in no virtue, whether justice, or temperance, or holiness? He would possess them all, and he would know which were dangers and which were not, and guard against them whether they were supernatural or natural; and he would provide the good, as he would know how to deal both with gods or men.
NICIAS: I think, Socrates, that there is a great deal of truth in what you say.
SOCRATES: But then, Nicias, courage, according to this new definition of yours, instead of being a part of virtue only, will be all virtue?
NICIAS: It would seem so.
SOCRATES: But we were saying that courage is one of the parts of virtue?
NICIAS: Yes, that was what we were saying.
