Materialist Theology
ELI5
Normally we think eternity is timeless and that time is just a poor copy of it — but "Materialist Theology" flips this: it says that the endless looping and repetition of time itself is what makes something eternal, with no heaven required.
Definition
Materialist Theology, as Žižek coins it in Less Than Nothing, names the structural paradox by which eternity is not a pre-given metaphysical substrate but is actively produced by temporal succession itself. The concept designates the hinge point where Hegelian dialectics, the Lacanian logic of the subject, and a Deleuzian account of repetition converge: retroactive causality — the circular movement whereby a cause is constituted only through and after its effects — is not a theological mystery but the very mechanism that generates what we call the eternal or the absolute. Temporality does not degrade or approximate a pre-existing eternity; it generates eternity as its retroactive residue. This is the "materialism" of the theology: no transcendent ground is presupposed — only the immanent loop of time positing its own presupposition.
The concept is therefore inseparable from the Lacanian logic of suture and the structure of the subject's self-constitution. Just as the subject in Logical Time precipitously concludes and thereby retroactively constitutes the earlier stages as its own preconditions, and just as the drive achieves its satisfaction not at a terminal goal but in the circular traversal of its path, so too does the loop of retroactive causality "create" eternity through sheer temporal movement. Žižek's formulation marks that this circular, self-positing structure — far from being idealist — is the core materialist insight: there is no eternity behind or above time, only time folding back on itself to produce the effect of the eternal.
Place in the corpus
In slavoj-zizek-less-than-nothing-hegel-and-the-shadow-of-dialectical-materialism-v, Materialist Theology appears at the intersection of the book's core theoretical wager — that dialectical materialism and psychoanalytic theory illuminate each other — and functions as a compressed formula for the entire argument about retroactive causality. It is not a standalone theological claim but a structural designation: the term "theology" is deliberately provocative, reclaiming the vocabulary of eternity and absolutes for a fully immanent, materialist account. Among the cross-referenced canonical concepts, it bears the closest relation to Logical Time (retroactivity, the moment of conclusion constituting its own preconditions), Drive (the satisfaction that lies in the loop rather than the terminus, the circuit as self-sufficient), and Repetition (the Deleuzian insistence that repetition produces difference and, here, produces eternity). It also touches Dialectics, since the self-positing loop is recognizably Hegelian — the Absolute positing its own presuppositions — but is pushed past Hegel's idealism into a materialist register.
The concept also carries implications for Desire and Objet petit a: if objet a is the structural remainder produced by the subject's self-constitution, then "Materialist Theology" could be read as the cosmological-scale version of that same operation — time's retroactive movement producing eternity as its own irreducible remainder, just as the subject's entry into the symbolic produces the a as its structural leftover. The concept is thus an extension and a generalization of several Lacanian structural principles, scaling them from the individual subject to a claim about the very nature of time and the eternal.
Key formulations
Less Than Nothing: Hegel and the Shadow of Dialectical Materialism (page unknown)
This is what one is tempted to call 'materialist theology': temporal succession creates eternity.
The phrase is theoretically loaded precisely because it places two apparently antithetical terms — "materialist" and "theology" — in apposition, forcing their contradiction to do conceptual work: "temporal succession" (the immanent, material movement of time) is declared the creator of "eternity" (classically the negation of temporal succession), inverting the standard metaphysical hierarchy and making eternity an effect rather than a ground.
