„Aesthetic hygiene is necessary for collective societies, for any social group residing together on a large scale. How? By programming environments that obey rigorous aesthetic criteria. Each time the inhabitant walks around in the city, he must bathe in a climate that creates in him a specific feeling of well-being, invoked by the massive presence of aesthetic products in the environment“
