Anti-Dühring is a book by Friedrich Engels, first published in German in 1877 in parts and then in 1878 in book form. It had previously been serialised in the newspaper Vorwärts. There were two further German editions in Engels` lifetime. This work was one of Engels`s major contribution to the exposition and development of Marxist theory. Its full title translates as Herr Eugen Dühring`s Revolution in Science: this is meant ironically and polemically. The short title recalls Julius Caesar`s polemic Anti-Cato. Anti-Dühring had produced his own version of socialism, intended as a replacement for Marxism. Since Karl Marx was busy at the time with writing Das Kapital, it was left to Engels to write a general defence. The sections are Philosophy, Political Economy and Socialism.
