 First, one might worry about the place of alienation in the evolution of Marx’s thought. The once-popular suggestion that Marx only wrote about alienation in his early writings—his published and unpublished works from the early 1840s—is not sustained by the textual evidence. However, the theoretical role that the concept of alienation plays in his writings might still be said to evolve. For example, it has been suggested that alienation in the early writings is intended to play an “explanatory role”, whereas in his later work it comes to have a more “descriptive or diagnostic” function (Wood 1981 [2004: 7]).
