Karen Barad's agential realism and psychoanalytic theory converge in their rejection of the Cartesian split between subject and object, yet they do so from different directions. Barad argues that phenomena—not things—are the basic units of existence, and that subject and object emerge only through “agential cuts” enacted by material-discursive apparatuses. Psychoanalysis similarly holds that subjectivity arises within scenes of interaction, where the poles of inner and outer, self and other, crystallize from relational processes rather than pre-existing entities.

The tension between the two frameworks lies in their treatment of symmetry. Barad posits a fundamental symmetry among agencies, human and nonhuman alike. Psychoanalysis, however, insists on constitutive asymmetries: between infant and caregiver, analyst and analysand, conscious and unconscious. These asymmetries are not hierarchical but developmental and ethical; they shape the very possibility of subject formation.

Barad's ontology gains depth when read through the psychoanalytic concepts of scene, unconscious, and transitional phenomena. Conversely, psychoanalysis benefits from Barad's insistence on the material-discursive entanglement of meaning and matter. A diffractive reading reveals not a fusion but a productive interference: an expanded understanding of how subjects and worlds co-emerge through processes that are at once material, symbolic, and ethically charged.
