All men are selfish, but the vain man is in love with himself. He admires, like the lover his adored one, everything which to others is indifferent.

Years teach us more than books.

People look with sympathetic eyes only at the blossom and the fruit, and disregard the long period of transition during which the one is ripening into the other.

Some men, like modern shops, hang everything in their show windows; when one goes inside, nothing is to be found.

Of all afflictions, the worst is self contempt.

What is all our knowledge worth? We do not even know what the weather will be tomorrow.
