There’s a fine line, when you encounter work close to your own, between the excitement that someone else considers your little area worth working on, and the worry that they might already have written the work that you are struggling to put together. This happened for me most recently when reading Kevin Anderson’s Marx at the Margins. As I’ve been trying to write about ways in which class reductionism misrepresents Marxism, Anderson’s detailed investigation of Marx’s writings on race, nationalism, and non-Western societies looked like it might render my gestures in that direction irrelevant. Luckily for me, Anderson’s book is actually the best sort of work to encounter, as it contains a huge amount of material on which one could build, while leaving enough theoretical space for others to do that building. Indeed, it is this combination of Anderson’s great aggregation of material with his comparatively sparse theorization of it that leads me to some thoughts about methodology for those of us attempting to construct theory through close dialog with particular texts and authors.
