The way social classes exist is closely related to representation. In this paper, I look at the representation of class difference from a psychoanalytic perspective, using the concepts of symbolic, imaginary and real register introduced by Jacques Lacan. These concepts make it possible to distinguish between different dimensions of representation (above all, the symbolic and imaginary dimensions), and also raise the question of the aporetic nature of any representation (thanks to the notion of the real register). The symbolic dimension is related to group formation (inclusion and exclusion) and points to the normative character of class identifications. Related to the imaginary dimension are the embodied images of self and others, driven by the dynamics of envy and resentment. The real dimension, on the other hand, is introduced by metaphors of lost objects and traumatic interclass violence. I use a variety of visual materials and literary texts from different historical moments of capitalist social formation to illustrate the analyses of the three registers. In the concluding section of the text, I describe the interconnectedness of the three registers using the example of an excerpt from the biographical narrative of a worker. In the conclusion, I address the contemporary opacity of class relations, but I do not interpret it as an indicator of the "death of classes," but as a historical moment of the disarticulation of class difference.
