We owe to the Middle Ages the two worst inventions of humanity - romantic love and gunpowder.

Everything that is in agreement with our personal desires seems true; everything that is not puts us in a rage.

Old age is far more than white hair, wrinkles, the feeling that it is too late and the game finished, that the stage belongs to the rising generations. The true evil is not the weakening of the body, but the indifference of the soul.

The reading of a fine book is an uninterrupted dialogue in which the book speaks and our soul replies.

Either the soul is immortal and we shall not die, or it perishes with the flesh and we shall not know that we are dead. Live, then, as if you were eternal.

Advice is always a confession.

Two human beings anchored to one another are like two ships shaken by waves; their carcases collide with one another and creak.
