To perceive means to immobilize. To say this is to say that we seize, in the act of perception, something which outruns perception itself.

In just the same way the thousands of successive positions of a runner are contracted into one sole symbolic attitude, which our eye perceives, which art reproduces, and which becomes for everyone the image of a man who runs.

Our laughter is always the laughter of a group.

It is emotion that drives the intelligence forward in spite of obstacles.

Sex-appeal is the keynote of our whole civilization.

For life is tendency, and the essence of a tendency is to develop in the form of a sheaf, creating, by its very growth, divergent directions among which its impetus is divided.

In laughter we always find an unavowed intention to humiliate and consequently to correct our neighbour.
