The great advantage of a novel is you can put in whatever comes into your head - it has the same shape as the human brain.
Michel HouellebecqA source of permanent, accessible pleasure, our genitals exist. The god who created our misfortune, who made us short-lived, vain and cruel, has also provided this form of meagre compensation. If we couldn't have sex from time to time, what would life be? A futile struggle against joints that stiffen, caries that form. All of which, moreover, is as uninteresting as humanly possible - the collagen which makes muscles stiffen, the appearance of microbic cavities in the gums.
