Far best is he who is himself all-wise, and he, too, good who listens to wise words; But whoso is not wise or lays to hear another's wisdom is a useless man.
HesiodIt is a hard thing for a man to be righteous, if the unrighteous man is to have the greater right.
HesiodEvil can be got very easily and exists in quantity: the road to her is very smooth, and she lives near by. But between us and virtue the gods have placed the sweat of our brows; the road to her is long and steep, and it is rough at first; but when a man has reached the top, then she is easy to attain, although before she was hard.
Hesiod
