 Second, much analytical Marxist work is by individuals who are not participants in the September Group. A list of some of these, drawn from assorted secondary literature, might include: Alan Carling, Norman Geras, Andrew Levine, Daniel Little, Richard Miller, Charles W. Mills, Richard Norman, Jeffrey Reiman, Debra Satz, David Schweickart, William Shaw, Tommie Shelby, Elliot Sober, Ian Steedman, Nicholas Vrousalis, Robert Paul Wolff, and Allen Wood. All of those have been characterised as producing work, at some point, in the analytical Marxist mode, albeit that the list includes individuals who would not identify themselves as analytical Marxists, and others who have themselves criticised narrower versions of the tradition, such as rational choice Marxism (Wolff 1990)).
