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, and Philippe van Parijs.
