This is the fundamental idea of culture, insofar as it sets but one task for each of us: to further the production of the philosopher, of the artist, and of the saint within us and outside us, and thereby to work at the consummation of nature.
One can generally say this about men: that they are ungrateful, fickle, simulators and deceivers, avoiders of danger, greedy for gain; and while you work for their good they are completely yours, offering you their blood, their property, their lives, and their sons when danger is far away; but when it comes nearer to you, they turn away.
Somebody insults you and you feel anger. Don't miss this opportunity; try to understand why, why this anger. And don't make it a philosophical thing. Don't go to the library to consult about anger. Anger is happening to you -- it is an experience, a live experience. Focus your whole attention on it and try to understand why it is happening to you. It is not a philosophical problem. No Freud is to be consulted about it. There is no need! It is just foolish to consult somebody else while anger is happening to you. You can touch it. You can taste it. You will be burned by it.
