Under the pressure of instinct man recognizes the animal in himself, the plant in himself, and even a strange affinity with the inorganic and the inanimate. It is instinct in us which attracts us so strangely to the earth under our feet. It is instinct which attracts certain individual souls to certain particular natural elements, such as air, fire, sand, mould, rain, wind, water, and the like; a kind of remote atavistic reciprocity in us stretching out towards that particular element. It is by means of instinct that we are able to sink into that mysterious sub-conscious world which underlies the conscious levels of every soul-monad. Under the groping and fumbling guidance of this strange power we seem to come into touch with the profoundest reservoirs of our personal identity.
Considering what fantastic and cruel tricks the lonely thinking power, the abstract reason, has been allowed to play us it is no wonder that this French philosopher has been tempted to turn away from reason and find in instinct the ultimate solution. Instinct, as we give ourselves up to it, seems to carry us into the very nerves and tissues and veins and pulses of life. Its verdicts seem to reach us with an absolute and unquestionable authority. They seem to bear upon them an "imprimatur" more powerful than any moral sanction. Potent and terrible, direct and final, instinct seems to rise up out of the depths and break every law.
It leaps forth from our inmost being like a second self more powerful than we are. It invades religion. It incarnates itself in lust. It obsesses taste. It masquerades as intuition. It triumphs over reason. With an irrationality, that seems at the same time terrible and beautiful, instinct moves straight to its goal. It follows its purpose with demonic tenacity, heedless of logic, contemptuous of consequences. It cares nothing for contradictions. It forces contradictions to lose themselves in one another according to some secret law of its own, unknown to the law of reason.
Such, then, is instinct, the sub-conscious fatality of Nature so difficult to control; whose unrestrained activity is capable of completely destroying the rhythm of the complex vision. Nothing but the power of the apex-thought of man's whole concentrated being is able to dominate this thing. It may be detected lurking in the droop of the Sphinx's eyelids and in the cruel smile upon her mouth. But the answer given to the challenge of this subterranean force is not, after all, any logical judgment of the pure reason. It is the answer of the vision of the artist, holding its treacherous material under his creative hand.
