In our article, “The Faces of Reason and Its Critics”, Dialogue 25/1 (Spring 1986), 105–118, Elizabeth Trott and I said (106) that, in his presidential address to the Canadian Philosophical Association (Dialogue 16/1 [March 1977], 3–21), Francis Sparshott “mysteriously seemed to have confused … John Clark Murray … with John Macmurray”. In footnote 6 (107), we reported Martyn Estall's theory that there might, indeed, have been no confusion because Sparshott probably did mean Macmurray who was being “promoted” at Queen's at the time. Professor Sparshott reports that Professor Estall's surmise is the correct solution to the “mystery”. He also reminds us that, when he came to Canada in 1950 he was at University College, Toronto. Later, from 1955 onwards, he was John Irving's colleague at Victoria College.
