 Harold Prichard was the acknowledged leader of a group of moral philosophers who worked together in Oxford between the two World Wars, and which included W. D. Ross, E. F. Carritt (a pupil of Prichard’s) and H. W. B. Joseph. These men, together with C. D. Broad and A. C. Ewing, who worked at Cambridge, have come to be known as the British Intuitionists.
