I hold therefore that it is in this unconscious life of ours, in this existence that is so vast, so divine, so inexhaustible and unfathomable, that we must seek for the explanation of fortunate or contrary chances. Within us is a being that is our veritable ego, our first-born: immemorial, illimitable, universal, and probably immortal. Our intellect, which is merely a kind of phosphorescence that plays on this inner sea, has as yet but faint knowledge of it. But our intellect is gradually learning that every secret of the human phenomena it has hitherto not understood must reside there, and there alone. This unconscious being lives on another plane than our intellect, in another world. It knows nothing of Time and Space, the two formidable but illusory walls between which our reason must flow if it would not be hopelessly lost. It knows no proximity, it knows no distance; past and future concern it not, or the resistance of matter. It is familiar with all things; there is nothing it cannot do. To this power, this knowledge, we have indeed at all times accorded a certain varying recognition; we have given names to its manifestations, we have called them instinct, soul, unconsciousness, sub-consciousness, reflex action, presentiment, intuition, &c. We credit it more especially with the indeterminate and often prodigious force contained in those of our nerves that do not directly serve to produce our will and our reason: a force that would appear to be the very fluid of life. Its nature is probably more or less the same in all men; but it has very different methods of communicating with the intellect. In some men this unknown principle is enshrined at so great a depth that it concerns itself solely with physical functions and the permanence of the species; whereas in others it would seem to be for ever on the alert, rising again and again to the surface of external and conscious life, which its fairy-like presence quickens; intervening at every instant, warning, deciding, counselling; blending with most of the essential facts of a career. Whence comes this faculty? There are no fixed or certain laws. We do not detect, for instance, any constant relation between the activity of the unconsciousness and the development of the intellect. This activity obeys rules of which we know nothing. So far as we at present can tell, it would seem to be purely accidental. We discover it in one man, and not in another; nor have we any clue that shall help us to guess at the reason of this difference. 11
