Universal prescriptivism, often simply called prescriptivism, is a meta-ethical theory about the semantical content of moral statements. It holds that moral statements functions similarly to imperatives which are universalizable — whoever makes a moral judgment is committed to the same judgment in any situation where the same relevant facts obtain. Since the concept was introduced by philosopher R. M. Hare in his 1952 book The Language of Morals, it has been compared to emotivism and to the categorical imperative of Immanuel Kant.
