Domenico Losurdo (14 November 1941 – 28 June 2018) was an Italian Marxist philosopher and historian. An influential figure, praised by many for his criticism of liberalism in practice and criticised by others for relativising Joseph Stalin, Losurdo was best known for his critique of anti-communism, colonialism, imperialism, the European tradition of liberalism and the concept of totalitarianism. Losurdo also articulated a distinction between political-moral and naturalistic despecification.
