Adam Morton FRSC (1945 – 2020) was a Canadian philosopher. Morton's work focused on how we understand one another's behaviour in everyday life, with an emphasis on the role mutual intelligibility plays in cooperative activity. He also wrote on ethics, decision-making, philosophy of language and epistemology. His later work concerned our vocabulary for evaluating and monitoring our thinking. Morton was Professor of Philosophy from 1980 to 2000 at the University of Bristol in the UK and finished his academic career at the University of British Columbia. He was president of the Aristotelian Society during 1998–1999 and in 2006 was elected a Fellow of the Royal Society of Canada.
