“The self-conscious feedback mechanism of the cortex allows us the hallucination that we are two souls in one body—a rational soul and an animal soul, a rider and a horse, a good guy with better instincts and finer feelings and a rascal with rapacious lusts and unruly passions. Hence the marvelously involved hypocrisies of guilt and penitence, and the frightful cruelties of punishment, warfare, and even self-torment in the name of taking the side of the good soul against the evil. The more it sides with itself, the more the good soul reveals its inseparable shadow, and the more it disowns its shadow, the more it becomes it.”

—Alan Watts, The Book: On the Taboo Against Knowing Who You Are, 1966.
