Idealism-Materialism Divide

The Idealism-Materialism Divide, as Žižek articulates it in The Parallax View, is not the familiar opposition between spirit and matter, or between mind and brain, but a precise logical-ontological divide over the status of the Event. Idealism, in this reframing, is the position that holds certain Events — love, political rupture, the emergence of consciousness, sexuality — to be irreducible to their material (pre)conditions: they arrive as a discontinuity that no causal-positive accounting of the substrate can close. Materialism, by contrast, does not mean crude reductionism (explaining mind away as neurons, or love away as biochemistry); rather, the materialist wager is the claim that one can get "behind" the Event — not to dissolve it, but to reconstruct the precise conditions of its emergence from the immanent inconsistency of the material order itself. This is a dialectical materialism, not an eliminativist one.

Žižek's move is to show that this divide has a structural homologue in the Hegelian and Lacanian tradition: the Badiouian Event-logic (an event irrupting from the situated void) is formally equivalent to the Hegelian non-All (the incomplete, self-contradictory totality that produces its own excess). The true materialist does not deny the Event's reality; she insists that the Event's irreducibility is itself a product of the constitutive incompleteness of the material order — what Lacan calls the not-all. To posit an Event that simply cannot be accounted for is, on this reading, idealism's defining gesture, because it hypostatizes a gap in material explanation into a positive ontological principle.

This concept appears in the-parallax-view-slavoj-zizek (p. 168) and serves as a hinge in Žižek's broader argument that the true stakes of contemporary philosophy are not epistemological but ontological-dialectical. It is positioned as a corrective reframing of the standard "humiliation" narrative (Copernicus, Darwin, Freud as successive desublimations), arguing that twentieth-century thought paradoxically rehabilitates appearance and Event rather than simply reducing them.

The concept cross-references several canonical nodes. It is most directly an intervention into the Badiouian Event: Žižek accepts Badiou's description of the Event as irrupting from the void of a situation, but insists that the idealist reading of Badiou would freeze this as an irreducible ontological positivity, whereas the materialist reading — aligned with the not-all — treats the Event's irruptive character as an index of the material order's own internal incompleteness and inconsistency. The Dialectics canon is equally at stake: the idealism-materialism divide is precisely where dialectics does or does not do its work; idealism arrests the dialectic at the moment of the Event's positivity, while materialism pushes the dialectic "behind" it. The reference to the Drive is implicit but structurally present — the drive's circular, non-teleological satisfaction around an impossible object is the libidinal counterpart of the materialist thesis that the "missing" object of an Event is not a transcendent ideal but an immanent gap. Knowledge enters insofar as the idealist move is also an epistemic surrender: declaring the Event unknowable-from-behind is, for Žižek, a refusal of the materialist labour of savoir.

idealism posits an ideal Event which cannot be accounted for in terms of its material (pre)conditions, while the materialist wager is that we can get 'behind' the event

The phrase "materialist wager" is theoretically loaded because it frames materialism not as a proven thesis but as a wager — a committed, risky bet — which structurally mirrors Badiou's notion of fidelity to an Event; meanwhile, "get 'behind' the event" (with its scare-quotes) signals that this is not naive causal reduction but a dialectical move through the Event's conditions, preserving the Event's reality while refusing to grant it an unaccountable idealist exception.
