A mind that questions everything, unless strong enough to bear the weight of its ignorance, risks questioning itself and being engulfed in doubt.

The roles of art, morality, religion, political faith, science itself are not to repair organic exhaustion nor to provide sound functioning of the organs. All this supraphysical life is built and expanded not because of the demands of the cosmic environment but because of the demands of the social environment.

There is a collective as well as an individual humor inclining peoples to sadness or cheerfulness, making them see things in bright or somber lights. In fact, only society can pass a collective opinion on the value of human life; for this the individual is incompetent.

There is no society known where a more or less developed criminality is not found under different forms. No people exists whose morality is not daily infringed upon. We must therefore call crime necessary and declare that it cannot be non-existent, that the fundamental conditions of social organization, as they are understood, logically imply it.

A mind that questions everything, unless strong enough to bear the weight of its ignorance, risks questioning itself and being engulfed in doubt.

Irrespective of any external, regulatory force, our capacity for feeling is in itself an insatiable and bottomless abyss.

The wise man, knowing how to enjoy achieved results without having constantly to replace them with others, finds in them an attachment to life in the hour of difficulty.
