Some Marxists posit what they deem to be Marx's theory of human nature, which they accord an important place in his critique of capitalism, his conception of communism, and his 'materialist conception of history'. Karl Marx, however, does not refer to "human nature" as such, but to Gattungswesen, which is generally translated as 'species-being' or 'species-essence'. According to a note from the young Marx in the Manuscripts of 1844, the term is derived from Ludwig Feuerbach’s philosophy, in which it refers both to the nature of each human and of humanity as a whole.
