April 28, 1861.--In the same way as a dream transforms according to its nature, the incidents of sleep, so the soul converts into psychical phenomena the ill-defined impressions of the organism. An uncomfortable attitude becomes nightmare; an atmosphere charged with storm becomes moral torment. Not mechanically and by direct causality; but imagination and conscience engender, according to their own nature, analogous effects; they translate into their own language, and cast into their own mold, whatever reaches them from outside. Thus dreams may be helpful to medicine and to divination, and states of weather may stir up and set free within the soul vague and hidden evils. The suggestions and solicitations which act upon life come from outside, but life produces nothing but itself after all. Originality consists in rapid and clear reaction against these outside influences, in giving to them our individual stamp. To think is to withdraw, as it were, into one’s impression--to make it clear to one’s self, and then to put it forth in the shape of a personal judgment. In this also consists self-deliverance, self-enfranchisement, self-conquest. All that comes from outside is a question to which we owe an answer--a pressure to be met by counter-pressure, if we are to remain free and living agents. The development of our unconscious nature follows the astronomical laws of Ptolemy; everything in it is change--cycle, epi-cycle, and metamorphosis. Every man then possesses in himself the analogies and rudiments of all things, of all beings, and of all forms of life. He who knows how to divine the small beginnings, the germs and symptoms of things, can retrace in himself the universal mechanism, and divine by intuition the series which he himself will not finish, such as vegetable and animal existences, human passions and crises, the diseases of the soul and those of the body. The mind which is subtle and powerful may penetrate all these potentialities, and make every point flash out the world which it contains. This is to be conscious of and to possess the general life, this is to enter into the divine sanctuary of contemplation.
