Our whole childhood remains to be reimagined. In reimagining it, we have the possibility of recovering it in the very life of our reveries as a solitary child.

Reverie is not a mind vacuum. It is rather the gift of an hour which knows the plenitude of the soul.

To live life well is to express life poorly; if one expresses life too well, one is living it no longer.

Ideas are refined and multiplied in the commerce of minds. In their splendor, images effect a very simple communion of souls.

Irony gives us, at little expense, the impression that we are experienced psychologists.

An excess of childhood is the germ of a poem.

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.
