Hayek's greatest intellectual debt was to Carl Menger, who pioneered an approach to social explanation similar to that developed in Britain by Bernard Mandeville and the Scottish moral philosophers in the Scottish Enlightenment. He had a wide-reaching influence on contemporary economics, politics, philosophy, sociology, psychology and anthropology. For example, Hayek's discussion in The Road to Serfdom (1944) about truth, falsehood and the use of language influenced some later opponents of postmodernism.
