Context

“not knowledge, but habituation or practice, and motive are what is required. Aristotle, in fact, at once attacked the Platonic teaching on the ground that moral virtue is like an art, such as medicine; the experienced practitioner is better than a man who has theoretical knowledge but no practical experience of disease and remedies. The issue turns, however, upon what is meant by knowledge. Aristotle's objection ignored the gist of Plato's teaching to the effect that man could not attain a theoretical insight into the good except as he had passed through years of practical habituation and strenuous discipline.” source
