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

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.

We must recognize the eloquence of our passions and refuse to be taken in. Instead of saying, 'That false friend always did despise me,' say: 'In my present state of agitation, I can't see clearly, I can't judge clearly; I am only a tragic actor who is declaiming for his own ears.' Then you will see the lights in the theater go out for lack of an audience, and the brilliant sets will be nothing more than painted cardboard.
