"The utmost extent of man's knowledge, is to know that he knows nothing" — Joseph Addison

Wisdom is the supreme part of happiness

Wise sayings often fall on barren ground, but a kind word is never thrown away

Wisdom, compassion, and courage are the three universally recognized moral qualities of men

Time is the wisest counselor of all

Wisdom is found only in truth

To conquer fear is the beginning of wisdom
