This paper considers some of what it means to work with, and within the limits to, Marxism. I make reference to two sets of inquiries where Marxism matters but remains at the margins of things. My focus will be on human cognition and digital life. To balance things, I then highlight some issues where Marxism is much more to the fore, specifically what I loosely refer to as "foodscapes." Finally, I conclude the essay with some further personal comments on my engagement with Marxism. Throughout, I want to give some expression to the sensation of walking a fine line between remaining committed to the conclusion that capitalist social relations are an enormous problem for human society but finding also that Marxism does not provide enough of the analytical equipment to answer how we should move beyond it. At the same time, I try to offer reflections on critical intellectual thought and action as a tentative and iterative experience, rather than an engagement framed by the security that one can find enough of what’s needed in Marxism.
