To begin to conceptualize class from a relational perspective, the author proposes that we consider how material relations that color interpersonal relations are absorbed into the psyche and the body. The term “class unconscious” is used to describe a kind of “thirdness”: the child's intersubjective communication with both the maternal and paternal working body. Stein's writing on the “enigmatic signifier” is revisited to describe that part of the parental body that arouses implicit then explicit awareness of the material world of work and class. The author argues that a relational theory of the subject must account for the infiltration of “objective” political phenomena into “subjective” experience. Clinical and autobiographical material illustrate the dynamics of the class unconscious in the transference.
