Richard Patrick Crosland Hanson, FBA, MRIA (1916–1988) was bishop of Clogher in the Church of Ireland from 1970 to 1973.
A historian of antiquity (he claimed to distrust history written concerning periods subsequent to 600 AD) he was particularly noted for a life of St. Patrick.
Among his writings was Reasonable Belief, which was written jointly with his brother, Anthony Tyrrell Hanson, a Professor of Theology at Hull University.
Rowan Williams described it as an indispensable tool for future researchers and stated that there is nothing else in English of comparable scope.
[3] Trevor A. Hart, lecturer in Systematic Theology in the University of Aberdeen, described it as the distillation of some twenty years' careful research and also stated that nothing comparable exists in either scale or erudition in the English language.
