Nothing is more dangerous than an idea when it is the only one you have.

There is a future that makes itself and a future we make. The real future is composed of both.

To think is to say 'no.'

As opposed to the incoherent spectacle of the world, the real is what is expected, what is obtained and what is discovered by our own movement. It is what is sensed as being within our own power and always responsive to our action.

It is not difficult to be unhappy or discontented; all you have to do is sit down, like a prince waiting to be amused. ... It is impossible to be happy if one does not have the desire to be happy; one must therefore will one's happiness, and create it.

What is a thousand years? Time is short for one who thinks, endless for one who yearns.

Nothing is more dangerous than an idea when it is the only one you have.
