There is only one way to avoid criticism: do nothing, say nothing, and be nothing.
Count your age by friends, not years. Count your life by smiles, not tears.
Where there is charity and wisdom, there is neither fear nor ignorance.
Wise men say nothing in dangerous times.
Wisdom is the daughter of experience.
Whenever you find yourself on the side of the majority, it is time to pause and reflect.
The well-bred contradict other people. The wise contradict themselves.
The stupid neither forgive nor forget; the naive forgive and forget; the wise forgive but do not forget.
The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
The attempt to combine wisdom and power has only rarely been successful and then only for a short while.
Science is organized knowledge. Wisdom is organized life.
Never tell your resolution beforehand.
