(495-406 B.C.), Greek tragic poet
Heaven never helps the man who will not act.
There is no witness so terrible—no accuser so powerful as conscience which dwells within us.
It is only great souls that know how much glory there is in being good.
To be doing good is man's most glorious task.
Without labor nothing prospers.
Who feels no ills, should, therefore, fear them; and when fortune smiles, be doubly cautious, lest destruction come remorseless on him, and he fall unpitied.
If you have committed iniquity, you must expect to suffer; for vengeance with its sacred light shines upon you.
Much wisdom often goes with fewest words.
