Karl Mannheim

Karl Mannheim (born Károly Manheim, 27 March 1893 – 9 January 1947) was a Hungarian sociologist and a key figure in classical sociology as well as one of the founders of the sociology of knowledge. Mannheim is best known for his book ''Ideology and Utopia'' (1929/1936), in which he distinguishes between partial and total ideologies, the latter representing comprehensive worldviews distinctive to particular social groups, and also between ideologies that provide support for existing social arrangements, and utopias, which look to the future and propose a transformation of society.
