Clinamen

Clinamen, borrowed from Epicurean-Lucretian atomism (the unpredictable swerve of atoms as theorised by Lucretius after Democritus), is appropriated within the Lacanian corpus as a structural concept naming the originary deviation or inclination that breaks symmetry at the very origin of any causal chain. It is not a merely cosmological curiosity but a formal principle: it names the point at which pure determinism (the automaton) fails to account for itself, where causality encounters its own inner crack. In the context of Seminar XI, the clinamen is explicitly linked to the tuché — the traumatic, missed encounter with the Real — as the pre-Socratic precedent for psychoanalysis's own discovery that development is animated not by smooth biological stages but by accident, obstacle, and the irreducible remainder that escapes the pleasure principle. The clinamen is what Democritus posited to prevent thought from collapsing into pure negativity or void: it is the minimal positive asymmetry that makes a world — and, by extension, a subject — possible.

In the post-Lacanian elaborations (Žižek, Dolar), clinamen is further elevated into a pivot for dialectical materialism. Žižek uses it to mark precisely the gap between Spinoza and Hegel: for Spinoza, Substance generates its own immanent multiplicity through clinamina (its productive differentiation), but remains ultimately a positive, self-sufficient ground. For Hegel — and for Lacan — the clinamen is instead the self-repelling Gap, the Nothingness that negates itself to produce something, rather than a positive Substance that differentiates. Dolar, meanwhile, identifies clinamen alongside tyche and den as the three Democritean notions Lacan retrieves precisely as "points of departure from causality" — the inner quirks or anomalies that are not breakdowns of materialism but its very condition of possibility.

The concept of clinamen appears most directly in the Seminar XI context (jacques-lacan-seminar-11, jacques-lacan-seminar-11-1), where it functions as the philosophical prehistory of the tuché. In those seminars, Lacan's argument is that psychoanalysis rediscovers — by an entirely different route — what pre-Socratic materialism needed the clinamen to do: explain how something moves, how a world or a subject comes to be, without appealing to teleology or biological necessity. Clinamen is thus the ancient name for what Lacan calls the Real's intrusion into the automaton — it is the missed encounter elevated to a cosmological principle, and it underwrites the claim that repetition in analysis is structured around tychic accident, not organic development. As an extension of the Gap concept, clinamen names the structural asymmetry that prevents any causal or symbolic order from being fully closed: it is the irreducible "less than nothing" that persists as the condition of movement, desire, and subjectivity.

In Žižek (slavoj-zizek-less-than-nothing-hegel-and-the-shadow-of-dialectical-materialism-v, slavoj-zizek-sex-and-the-failed-absolute-bloomsbury-academic-2019) and Dolar (subject-lessons-hegel-lacan-and-the-future-of-materialism-northwestern-universit), clinamen migrates from a clinical-structural register into an explicitly ontological and materialist one. Here it is positioned as the hinge concept for a Lacanian dialectical materialism: it is what separates Hegel (and Lacan) from Spinoza, since the Hegelian-Lacanian origin is not a self-differentiating Substance but a self-repelling Gap. In relation to the canonical concepts of Repetition, Gap, and Real in this corpus, clinamen functions as a specification of the originary moment at which the Real introduces itself into any causal or symbolic structure — not as brute positivity, but as the minimal swerve or inclination that is constitutive of both the world and the subject.

Lacan tried to retrieve the three notions of tyche, clinamen, and den from ancient philosophy precisely as the points of departure from causality, its inner quirks, as concomitant with the very possibility of materialism.

The phrase "points of departure from causality" is theoretically loaded because it reframes clinamen not as an exception or failure of causal law but as its constitutive inner quirk — the anomaly without which materialism itself could not be thought. By grouping clinamen with tyche and den as a triad retrieved by Lacan from ancient philosophy, the formulation reveals that psychoanalytic materialism is grounded precisely in what escapes or cracks determinism from within, rather than in any positive substance or mechanism.
