The world is not composed of heroes and villains, but of men and women with all the passions that God has given them. The ignorant condemn, but the wise pity.

The true Wisdom is in recognizing our own ignorance.

Education is the path from cocky ignorance to miserable uncertainty.

The highest wisdom has but one science - the science of the whole - the science explaining the whole creation and man's place in it.

Wisdom cries out in the streets, and no man regards it.

Though one should live a hundred years without wisdom and control, yet better, indeed, is a single day's life of one who is wise and meditative.
