To be wise, you must follow your intellect, even though such a way of life is often attacked.
The heavens do not approve when we sin, and the earth does not approve when we are virtuous.
—The TALMUD
Do not be interested in the quantity of people who respect and admire you, but in their quality. If bad people dislike you, so much the better.
—LUCIUS ANNAEUS SENECA
Human intellect is a divine lamp, and its light penetrates to the depth of things.
—EASTERN WISDOM
You should not be upset by the sight of wisdom being criticized. Wisdom would not be real wisdom if it did not reveal the stupidity of a bad life, and people would not be people if they endured this revelation without criticism.
