The Antinomy at the Heart of Critical Theory: Recovering Peter Gorsen's Forgotten Dissertation

In 1966, a doctoral student working under Theodor Adorno submitted a dissertation with a title that should have set off alarms across the Frankfurt Institute. Peter Gorsen called it Zur Phänomenologie des Bewußtseinsstroms. Bergson, Dilthey, Husserl, Simmel und die lebensphilosophischen Antinomien — "On the Phenomenology of the Stream of Consciousness: Bergson, Dilthey, Husserl, Simmel, and the Life-Philosophical Antinomies." The last word is the one that matters. Antinomien. Not contradictions to be resolved, not errors to be corrected, but antinomies: irreconcilable, structurally necessary oppositions that a system generates from within itself and cannot expel. The standard narrative of the 1960s intellectual crisis runs something like this: a generation of Marxist thinkers, frustrated by the perceived rigidity of dialectical materialism and the Frankfurt School's deepening pessimism, broke outward. They turned to Nietzsche, to Deleuze, to a vitalist counter-tradition that critical theory had supposedly excluded. The break was clean, the turn was external, and 1968 was its symbolic date. Gorsen's dissertation makes that narrative untenable. What he showed — systematically, across the work of Bergson, Dilthey, Husserl, and Simmel — is that the conceptual tensions between life-philosophy and critical theory were already internal to the Marxist tradition. They were not an outside force waiting to invade. They were an antinomical field that critical theory carried inside itself from the start, and that it could neither fully absorb nor fully reject without collapsing its own claims. The dissertation's argument is precise enough to be worth stating plainly. Gorsen traced how the "stream of consciousness" — a concept Bergson had developed to describe the fluid, non-spatialized character of lived experience — reappeared, transformed and often unacknowledged, in the phenomenological traditions that fed into Frankfurt School thought. Dilthey's hermeneutics of lived experience, Husserl's investigations of internal time-consciousness, Simmel's philosophy of life: these were not rivals to be defeated. They were resources that critical theory used while disavowing their origins. The antinomy, for Gorsen, was not between life-philosophy and critical theory as two competing schools. It was between critical theory's methodological self-understanding and the conceptual materials it actually deployed. This is where the suppression becomes analytically interesting, because it was not personal. Gorsen was not expelled or silenced in any dramatic sense. He went on to a career as an art historian, writing about outsider art and psychedelic aesthetics — a biographical continuation, arguably, of the very themes his dissertation had mapped. The suppression was structural. Adorno's own late work, particularly Aesthetic Theory (published posthumously in 1970), metabolizes motifs of flux, non-identity, and experiential immediacy that echo the life-philosophical currents Gorsen had systematized. But Adorno could not cite the dissertation that made those connections explicit without destabilizing the anti-Bergsonian, anti-vitalist posture that the Institute had maintained as official doctrine. Martin Jay's The Dialectical Imagination (1973) and Marxism and Totality (1984) document that posture thoroughly — and never mention Gorsen. The omission is not negligence. It is a symptom of the antinomy itself. The practical consequence for intellectual historians is a re-periodization. If the 1960s turn to vitalism was a return of something already latent, then the break point is not 1968. It is 1966, the year Gorsen's dissertation showed that the contradictions were internal and the synthesis was impossible. What followed — the Deleuzian moment, the Nietzsche renaissance, the turn to affect and embodiment — was not a defection from Marxism. It was an attempt to live inside an antinomy that had already been diagnosed, and that the official organs of critical theory had chosen to manage by silence rather than by argument. The takeaway is not that Gorsen was right and Adorno was wrong. That framing dissolves the antinomy into a contest, and the whole point is that it resists resolution. The takeaway is methodological: when a tradition systematically avoids naming the conceptual tensions that structure it, those tensions do not disappear. They go underground, resurface in altered form, and get mistaken for external ruptures when they finally become visible. Gorsen's dissertation is the map of that underground. Recovering it does not settle the debate between life-philosophy and critical theory. It shows that the debate was never between two external positions. It was always an antinomy internal to a single tradition — and the 1966 dissertation that named it has been waiting, in plain sight, for the historiography to catch up.
