“The pillars of civilisation are therefore morals and science, and both united. For science without morals degenerates into cynicism, and thus destroys the basis of the scientific effort itself; and morals without science degenerates into superstition and thus is apt to become fanatic cruelty. Science is the attempt to understand the universe and man; it is therefore identical with philosophy; it is not necessarily identical with modern science. By morals, we understand the rules of decent and noble conduct, as a reasonable man would understand them; those rules are by their nature applicable to any human being, although we may allow for the possibility that not all human beings have an equal natural aptitude for decent and noble conduct.”
Leo Strauss, “German Nihilism” (Conferència impartida l’any 1941 a la New School for Social Research, Nova York).
