Socrates and Plato are right: whatever man does he always does well, that is, he does that which seems to him good (useful) according to the degree of his intellect, the particular standard of his reasonableness.

The refinement of morality increases together with the refinement of fear. Today the fear of disagreeable feelings in other people is almost the strongest of our own disagreeable feelings.
