History proves nothing because it contains everything.

We have convictions only if we have studied nothing thoroughly.

To have committed every crime but that of being a father.

We rightly scorn those who have no made use of their defects, who have not exploited their deficiencies, and have not been enriched by their losses, as we despise any man who does not suffer at being a man or simply at being. Hence no graver insult can be inflicted than to call someone 'happy', no greater flattery than to grant him a 'vein of melancholy'... This is because gaiety is link to no important action and because, except for the mad, no one laughs when he is alone.

The deepest and most organic death is death in solitude, when even light becomes a principle of death. In such moments you will be severed from life, from love, smiles, friends and even from death. And you will ask yourself if there is anything besides the nothingness of the world and your own nothingness.

Psychoanalysis is a technique we practice at our cost; psychoanalysis degrades our risks, our dangers, our depths; it strips us of our impurities, of all that made us curious about ourselves.

The more intense a spiritual leader's appetite for power, the more he is concerned to limit it to others.
