To be happy, we must not be too concerned with others.

... unhappiness is like marriage. We believe we chose it, but then it is choosing us. That is how it is, we can do nothing about it.

The great courage is to stare as squarely at the light as at death.

One might think, that a period which, within fifty years, uproots, enslaves or kills seventy million human beings, should only, and forthwith, be condemned. But also its guilt must be understood.

We are living in the era of premeditation and the perfect crime. Our criminals are no longer helpless children who could plead love as their excuse. On the contrary, they are adults and the have the perfect alibi: philosophy, which can be used for any purpose - even for transforming murderers into judges.

The real passion of the twentieth century is servitude.

That's the way man is, cher monsieur. He has two faces: he can't love without self-love.
