Don't fear god, Don't worry about death; What is good is easy to get, and What is terrible is easy to endure

Let no one delay the study of philosophy while young nor weary of it when old.

When someone admits one and rejects another which is equally in accordance with the appearances, it is clear that he has quitted all physical explanation and descended into myth.

A beneficent person is like a fountain watering the earth, and spreading fertility; it is, therefore, more delightful to give than to receive.

Riches do not exhilarate us so much with their possession as they torment us with their loss.

Happiness is man's greatest aim in life. Tranquility and rationality are the cornerstones of happiness.

He who says either that the time for philosophy has not yet come or that it has passed is like someone who says that the time for happiness has not yet come or that it has passed.
