J. O. Urmson

David Heyd records that "the history of supererogation in non-religious ethical theory" began with Urmson's 'seminal' "Saints and Heroes" (1958). This paper, according to Heyd, "opened the contemporary discussion of supererogation," while hardly mentioning the term, "by challenging the traditional threefold classification of moral action: the obligatory, the permitted (or indifferent) and the prohibited."

After World War II, Urmson's book Philosophical Analysis (1956) – an overview of the development of analytic philosophy at Cambridge and Oxford universities between World War I and World War II – was influential in the post-war spread of analytic philosophy in Anglophone countries.

In 1955 he accepted an appointment as Professor of Philosophy at Queen's College Dundee, then part of the University of St Andrews in Scotland. In 1959 he returned to Oxford as a Fellow of Corpus Christi College, Oxford and a Tutor in Philosophy. Except for visiting appointments in the United States (e.g. Visiting Associate Professor of philosophy at Princeton University in 1950–51), he remained at Oxford until his retirement, at which point he assumed the position of Henry Waldgrave Stuart Professor of Philosophy, Emeritus, at Stanford University.

After the war he was a Student (i.e. a Fellow) of Christ Church, Oxford from 1945 to 1955. During this period he lived in Monckton Cottage in Headington, Oxford.

James Opie Urmson (4 March 1915 – 29 January 2012), was a philosopher and classicist who spent most of his professional career at Corpus Christi College, Oxford. He was a prolific author and expert on a number of topics including British analytic/linguistic philosophy, George Berkeley, ethics, and Greek philosophy (especially Aristotle).

J. O. Urmson was born in Hornsea. He was named after his father, the Rev. James Opie Urmson (1881–1954), a Methodist Minister. Urmson was educated at Kingswood School, Bath (1928–1934) and Corpus Christi College, Oxford (1934–38).
