Orthdoxy is my doxy; heterodoxy is another man’s doxy.

William Warburton (1698-1779) English critic and churchman

(Attributed)

In Joseph Priestley, Memoirs, Vol. 1:

“I have heard frequent use,” said the late Lord Sandwich, in a debate on the Test Laws, “of the words ‘orthodoxy’ and ‘heterodoxy;’ but I confess myself at a loss to know precisely what they mean.” “Orthodoxy, my Lord,” said Bishop Walburton, in a whisper,—“orthodoxy is my doxy; heterodoxy is another man’s doxy.”
