Real orgies are never so exciting as pornographic books. In a volume by Pierre Louys all the girls are young and their figures perfect; there's no hiccoughing or bad breath, no fatigue or boredom, no sudden recollections of unpaid bills or business letters unanswered, to interrupt the raptures. Art gives you the sensation, the thought, the feeling quite pure--chemically pure, I mean,... not morally.
