Some thinkers hold that it is by nature that people become good, others that it is by habit, and others that it is by instruction. Just as a piece of land has to be prepared beforehand if it is to nourish the seed, so the mind of the pupil has to be prepared in its habits if it is to enjoy and dislike the right things.
