Nothing is forgotten in the processes of idealization. Reveries of idealization develop, not by letting oneself be taken in by memories, but by constantly dreaming the values of a being whom one would love. And that is the way a great dreamer dreams his double. His magnified double sustains him.

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.
