English usage is based on a tradition going back to medieval literature, where the opposition of nature ("instinct, inclination") norreture ("culture, adopted mores") is a common motif, famously in Chretien de Troyes' Perceval, where the hero's effort to suppress his natural impulse of compassion in favor of what he considers proper courtly behavior leads to catastrophe.
