Some are born with knowledge, some derive it from study, and some acquire it only after a painful realization of their ignorance. But the knowledge being possessed, it comes to the same thing. Some study with a natural ease, some from a desire for advantages, and some by strenuous effort. But the achievement being made, it comes to the same thing.
When the Superior Man eats he does not try to stuff himself; at rest he does not seek perfect comfort; he is diligent in his work and careful in speech. He avails himself to people of the Tao and thereby corrects himself. This is the kind of person of whom you can say, "he loves learning."
When a man's knowledge is sufficient to attain, and his virtue is not sufficient to enable him to hold, whatever he may have gained, he will lose again.
Every piece of marble has a statue in it waiting to be released by a person of sufficient skill to chip away the unnecessary parts. Just as the sculptor is to the marble, so is education to the soul. It releases it. For only educated people are free people. You cannot create a statue by smashing the marble with a hammer, and you cannot by the force of arms release the spirit or the soul of people.
Friendship with the upright, with the truthful and with the well informed is beneficial. Friendship with those who flatter, with those who are meek and who compromise with principles, and with those who talk cleverly is harmful.
