“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
“The idea which man forms of beauty imprints itself throughout his attire, rumples or stiffens his garments, rounds off or aligns his gestures, and, finally, even subtly penetrates the features of his face.”
—Charles Baudelaire (1821–1867)
