Flat Ontology

Flat ontology is a theoretical position, associated primarily with new materialist and speculative realist thinkers (Jane Bennett, Levi Bryant, and the broader assemblage-theory tradition), that posits a single, undifferentiated plane of being on which all entities—human and nonhuman, organic and inorganic—exist as equivalent actants or objects. As Bryant's formulation has it: "there is only one type of being: objects." Within this framework, the human subject loses any ontologically privileged status and becomes merely one node among many in a heterogeneous network of agencies and forces; difference is acknowledged, but only against a "backdrop of radical sameness."

The Lacanian and post-Lacanian critique of flat ontology, as developed across the sources, turns on a double reversal. First, the ostensibly "inhuman" or post-humanist gesture of flat ontology secretly presupposes the very Cartesian subject (the cogito, the barred $) it claims to dissolve: in order to occupy the "view from nowhere" from which all entities appear as equivalent actants, one must already have evacuated subjectivity to a pure formal position—which is precisely the structure of the split subject sustained by objet petit a. Second, and more decisively, flat ontology suppresses the constitutive asymmetry that psychoanalysis insists upon: there is no "vibrant matter," no object with thing-power, without the subject's anamorphic distortion—no objet a without $, and no $ without a. The Real of sexuality, the drive, and fantasy introduce an ontological negativity, a gap or crack in being, that a flat ontology systematically forecloses. By leveling all entities onto one plane, flat ontology also forecloses the possibility of a properly materialist ethics grounded in that constitutive gap, substituting for it a descriptive ecology of forces that cannot account for freedom, desire, or ideological critique.

In the corpus, "flat ontology" functions primarily as a critical foil rather than a position endorsed by the sources. In slavoj-zizek-sex-and-the-failed-absolute-bloomsbury-academic-2019 (p.360), Žižek deploys the term to expose a performative contradiction in assemblage theory: the "inhuman view" that reduces the subject to one actant among others tacitly reinstates a pure Cartesian cogito at the vanishing point of observation, a cogito that is itself constituted and sustained by objet petit a as surplus-enjoyment/surplus-value. The encounter with flat ontology here opens onto Žižek's broader argument that capitalism uniquely strips bare the mechanism of objet a, making visible what other historical formations kept concealed. In subject-lessons-hegel-lacan-and-the-future-of-materialism-northwestern-universit (pp.188, 248), the term is examined more systematically as the defining ontological commitment of new materialism. The argument there is that the Lacanian logic of extimacy—objet petit a as simultaneously inside and outside the subject—structurally refutes flat ontology's claim to have done away with the subject/object distinction: sublimation and "thing-power" are themselves products of the subject's anamorphic relation to the void, meaning that what new materialism calls vibrant matter is always already the objectal form of the subject's constitutive lack.

Relative to the cross-referenced canonical concepts, flat ontology serves as a kind of theoretical negative image. Objet petit a, Fantasy, and the Real all designate modes of irreducible asymmetry within being—a remainder that cannot be absorbed into any homogeneous field. Flat ontology attempts to dissolve precisely this asymmetry. The Splitting of the Subject ($) and Surplus-jouissance mark the points where being is cracked from within—points that a flat ontology cannot register because it has no category for the constitutive gap. The concept also intersects with Ideology insofar as the leveling gesture of flat ontology can itself be read ideologically: by neutralizing the peculiarity of the subject and of sexuality as ontological negativity, it forecloses the psychoanalytic critique of capitalist ideology that depends on those categories. Flat ontology thus occupies the corpus as the symptomatic limit-case of new materialism—a position that must be engaged and refuted for the Lacanian materialist alternative to be articulated.

What proponents of such a 'flat ontology' posit, to take Levi Bryant as a paradigmatic example of this type of new materialist/realist thinking, is that 'there is only one type of being: objects.'

The quote is theoretically loaded because the phrase "only one type of being: objects" names the precise leveling operation that the Lacanian account of subjectivity (the barred $, objet a, the Real) is designed to contest: by collapsing ontological heterogeneity into a single flat plane of "objects," Bryant's formulation eliminates the structural asymmetry—between subject and object, between $ and a—on which the entire psychoanalytic account of desire, fantasy, and surplus-jouissance depends.
