"[She] was therefore born of a situation which brutally reveals the irreconcilable duality of body and soul, that fundamental human experience.
A long time ago, man would listen in amazement to the sound of regular beats in his chest, never suspecting what they were. He was unable to identify himself with so alien and unfamilar an object as the body. The body was a cage, and inside that cage was something which looked, listened, feared, thought, and marveled; that something, that remainder left over after the body had been acounted for, was the soul.
Today, of course, the body is no longer unfamiliar: we know that the beating in our chest is the heart and that the nose is the nozzle of a hose sticking out of the body to take oxygen to the lungs. the face is nothing but an instrument panel registering all the body mechanisms: digestion, sight, hearing, respiration, thought.
Ever since man has learned to give each part of the body a name, the body has given him less trouble. He has also learned that the soul is nothing more than the gray matter of the brain in action. It old duality of body and soul has become shrouded in scientific terminology, and we can laugh at it as merely and obsolete prejudice.
But just make someone who has fallen in love listen to his stomach rumble, and the unity of body and soul, that lyrical illusion of the age of science, instantly fades away."
