The Phantom Genealogy: How a Frankfurt School Dissertation Became a Theory of Psychedelic Art

When a book is left unread in a corner of the house, it does not stop speaking. It simply learns a new language — the language of neglect, of whisper rather than declaration. Peter Gorsen’s 1966 dissertation was such a book. Submitted at the University of Frankfurt under Theodor Adorno’s gaze, it carried a title long enough to fill an entire shelf: Zur Phänomenologie des Bewußtseinsstroms. Bergson, Dilthey, Husserl, Simmel und die lebensphilosophischen Antinomien. In plain words: the stream of consciousness and the life-philosophical antinomies, read through the very thinkers the Frankfurt School had officially banished as irrationalist. And then it disappeared — not into flames, but into the family archive, into the silence between Adorno’s late lectures and the standard histories that never mention its name. Most scholars now assume that Gorsen simply abandoned his early philosophical inquiry. They see his later career as a turn, a change of interest: an art historian specialising in outsider art, psychedelic painting, and the Vienna Fantastic Realists — books on Ernst Fuchs, exhibitions on Kunst und Bewusstseinserweiterung, a whole existence given to images rather than propositions. That reading is tidy, but it is false. It treats the dissertation as a forgotten first draft, when in fact it was the first tremor of an argument that would force its way into a different medium because the original one had been walled off. The dissertation itself is a phantom genealogy. Gorsen traced how critical theory’s concepts of reification and consciousness — the rigid structures of identity-thinking — could be re-grounded in Bergson’s durée, Dilthey’s lived experience, Husserl’s phenomenological reduction, Simmel’s vital flux. This was not a repudiation of Adorno; it was a quiet demonstration that the School’s own tools had a secret bloodline they refused to acknowledge. The official posture was aggressively anti-Bergsonian, anti-vitalist. Martin Jay’s The Dialectical Imagination and Marxism and Totality document that stance in careful detail, never mentioning Gorsen’s work, never noting that a student inside the Institute had already spliced that lineage into the canon’s wiring. After 1966, Gorsen never again wrote philosophy of that kind. This is the moment where the creature is pushed behind a closed door. But that push was structural, not merely personal. Adorno’s own late Aesthetic Theory (1970) and his subterranean lectures on Husserl show an anxious metabolism of the very motifs the dissertation had made explicit. Yet the academic machinery could not absorb Gorsen’s explicit thesis; it could only encrypt it — and Gorsen, unlike his teacher, could not encrypt and stay. What happens to an argument when the household can no longer tolerate its presence? It undergoes a metamorphosis. Gorsen’s subsequent career — his monographs on Ernst Fuchs, his deep dives into psychedelic aesthetics, his study of the Vienna Fantastic Realists — is the dissertation’s argument, now expressed in the grammar of paint and altered states instead of philosophical prose. The stream of consciousness, that Bergsonian flow the Institute had treated as a danger, reappears as an object of explicit investigation in his exhibitions and texts. In Kunst und Bewusstseinserweiterung (“Art and Consciousness Expansion”), the dissolution of the bounded self, the Husserlian epochē, the durée that resists reification — all are present, but no longer couched in the vocabulary that would have triggered the old guard. The medium had changed from text to image because text had been sealed shut. This is not a story of a man traumatised into silence. It is a record of structural migration. The Institute’s suppression had a material, biographical trace: follow Gorsen into the galleries of 1970s Vienna and you will find the same inquiry into lived temporality, the same critique of instrumental reason through a renewed attention to inner experience. The argument did not die; it became an aesthetic practice, one that could move through the art world without needing approval from a philosophy department that had already decided these questions were illegitimate. The practical lesson here is simple and uncomfortable. If you want to understand what a discipline has repressed, do not limit yourself to its archives. Follow the scholar who was forced to leave — or who quietly drifted — and see where the questions landed. Gorsen’s trajectory shows that intellectual suppression does not produce an empty space; it produces a parallel archive, one built out of the materials the official lineage cannot digest. The dissertation’s ghost lives not in the Frankfurt School’s collected works but in the psychedelic iconography of the Fantastic Realists, in the outsider artists he championed, in a body of thought that never stopped speaking, only altered its voice.
