“ Lastly, in the deepest and dimmest recesses of the unconscious,​ there lurks the nature of man himself. On it, clearly, he will concentrate the supreme effort of his mind and of his creative initiative. Mankind will not have ceased to crawl before God, Tsar and Capital only in order to surrender meekly to dark laws of heredity and blind sexual selection. Man will strive to control his own feelings, to raise his instincts to the height of his conscious mind, and to bring clarity into them; to channel his will-power into his unconscious depths; and in this way he will lift himself into new eminence.
— Leon Trotsky
