The Greek word which we translate as 'virtue' or 'excellence' meant primarily 'efficiency at a task'. It was the philosopher Aristotle, Plato's greatest pupil, who defined it as 'the right condition of the soul'.
Human beings have bodies, minds, and characters. Each of these is capable of what the Greeks call 'virtue'. The virtue or excellence of the body is health and fitness and strength, the firm and sensitive hand, the clear eye; the excellence of the mind is to know and to understand and to think, to have some idea of what the world is and of what the human has done and has been and can be; the excellence of the character lies in the great virtues.
This trinity of body, mind and character is our humanity: the human's aim, besides earning a living, is to make the most of all three, to have as good a mind, body and character as possible; and a liberating education, a person's education, is to help them to this; not because a sound body, mind and character help promote success, or even because they help promote happiness, but because they are good things in themselves, and because what is good is worthwhile, simply because it is good.
