Sophocles

Think not that thy word and thine alone must be right.

Reason is God's crowning gift to man.

It is better not to live at all than to live disgraced.

And if my present deeds are foolish in thy sight, it may be that a foolish judge arraigns my folly.

Fortune is not on the side of the faint-hearted.

To be doing good deeds is man's most glorious task.

If it were possible to heal sorrow by weeping and to raise the dead with tears, gold were less prized than grief.

Those griefs smart most which are seen to be of our own choice.

Heaven never helps the man who will not act.

Rather fail with honor than succeed by fraud.
