" Soul and body, body and soul—how mysterious they were! There was animalism in the soul, and the body had its moments of spirituality. The senses could refine, and the intellect could degrade. Who could say where the fleshly impulse ceased, or the psychical impulse began? How shallow were the arbitrary definitions of ordinary psychologists! And yet how difficult to decide between the claims of the various schools! Was the soul a shadow seated in the house of sin? Or was the body really in the soul, as Giordano Bruno thought? The separation of spirit from matter was a mystery, and the union of spirit with matter was a mystery also. "
― Oscar Wilde , The Picture of Dorian Gray
