Analytical Marxism is an approach to Marxist theory that was prominent amongst English-speaking philosophers and social scientists during the 1980s. It was mainly associated with the September Group of academics, so called because of their biennial September meetings to discuss common interests. Self-described as "Non-Bullshit Marxism", the group was characterized, in the words of David Miller, by "clear and rigorous thinking about questions that are usually blanketed by ideological fog." The most prominent members of the group were G. A. Cohen, John Roemer, Jon Elster, Adam Przeworski, Erik Olin Wright, Hillel Steiner, Philippe van Parijs, and Robert-Jan van der Veen.
