This title presents an insight into moral skepticism of the 20th century. The author argues that our every-day moral codes are an ‘error theory’ based on the presumption of moral facts which, he persuasively argues, don’t exist. His refutation of such facts is based on their metaphysical ‘queerness’ and the observation of cultural relativity.
