There is only one thing worse than boredom, and that is the fear of boredom.

If we had the courage to confront the doubts we timidly conceive about ourselves, none of us would utter an 'I' without shame.

We have convictions only if we have studied nothing thoroughly.

All that shimmers on the surface of the world, all that we call interesting, is the fruit of ignorance and inebriation.

We cannot consent to be judged by someone who has suffered less than ourselves. And since each of us regards himself as an unrecognized Job.

Knowledge, having irritated and stimulated our appetite for power, will lead us inexorably to our ruin.

Tolerance cannot seduce the young.
