In scientific thought, the concept functions all the better for being cut off from all background images. In its full exercise, the scientific concept is free from all the delays of its genetic evolution, an evolution which is consequently explained by simple psychology. The virility of knowledge increases with each conquest of the constructive abstraction.

Poetry is one of the destinies of speech... One would say that the poetic image, in its newness, opens a future to language.

We comfort ourselves by reliving memories of protection. Something closed must retain our memories, while leaving them their original value as images.
