"It all comes down to wisdom really. In Nicomachean Ethics, Aristotle says, “Now it is thought to be the mark of a man of practical wisdom to be able to deliberate well about what is good and expedient for himself . . . about what sort of things conduce to the good life in general” (VI, 1140a–1140b) because “it is impossible to be practically wise without being good” (1144a, 36–37). To be fully human, to have a whole and full education, is to know what is good."
