Beware of thinkers whose minds function only when they are fueled by a quotation.

All great ideas should be followed by an exclamation mark - a warning signal similar to the skull and crossbones drawn on high-voltage transformers.

My enthusiasms...constitute my reserves, my unexploited resources, perhaps my future.

Impossible to spend sleepless nights and accomplish anything: if, in my youth, my parents had not financed my insomnias, I should surely have killed myself.

Melancholy: an appetite no misery satisfies.

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

History proves nothing because it contains everything.
