Following the Second World War, Crawshay-Williams focused largely on philosophy. His first book, The Comforts of Unreason, was published in 1947. According to Michael Potter, this was "a light and witty exposé of the human inclination towards deception, self-deception in particular". Potter adds:The Comforts of Unreason identifies and catalogues forces that lead minds astray – fallacious reasoning, euphemism, propaganda, and unacknowledged desires. Crawshay-Williams followed Russell and W. K. Clifford in emphasizing the necessity of basing beliefs on available evidence.Crawshay-Williams' best-known work is 1957's Methods and Criteria of Reasoning (1957), in which he attempted to explain "why so many theoretical and philosophical controversies seem to be intractable" (Potter). He is best remembered today as influential in the fields of argumentation theory, rhetoric, and communications studies, and on the work of Stephen Toulmin, Lucy Olbrechts-Tyteca, and Chaim Perelman. == Works ==
