Imagination is a tree. It has the integrative virtues of a tree. It is root and boughs. It lives between earth and sky. It lives in the earth and the wind. The imagined tree imperceptibly becomes a cosmological tree, the tree which epitomises a universe, which makes a universe.

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

The psychology of the alchemist is that of reveries trying to constitute themselves in experiments on the exterior world. A double vocabulary must be established between reverie and experiment. The exaltation of the names of substances is the preamble to experiments on the "exalted" substances.

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.

I am a dreamer of words, of written words. I think I am reading; a word stops me. I leave the page. The syllables of the word begin to move around. Stressed accents begin to invert. The word abandons its meaning like an overload which is too heavy and prevents dreaming. Then words take on other meanings as if they had the right to be young. And the words wander away, looking in the nooks and crannies of vocabulary for new company, bad company.
