The theory associated with Immanuel Kant (1724-1804), that only acts done from a motive of duty have moral value. It is a stern moral philosophy, close to Stoicism, which holds that virtue is its own reward and therefore "duty for duty's sake" is man's highest moral imperative. (Etym. Greek deon, that which is obligatory + logia, science, knowledge.)
