Hare, R. M.

Richard Mervyn Hare (21 March 1919 in Backwell, Somerset – 29 January 2002 in Ewelme, Oxfordshire) was an English moral philosopher who held the post of White's Professor of Moral Philosophy at the University of Oxford from 1966 until 1983 and then taught for a number of years at the University of Florida. His meta-ethical theories were influential during the second half of the twentieth century.

Hare is best known for his development of prescriptivism as a meta-ethical theory. He believed that formal features of moral discourse could be used to show that correct moral reasoning will lead most agents to a form of preference utilitarianism. [Wikipedia]
