The God You Wore Last Tuesday

John Lilly published *Simulations of God* in 1976, the same year Apple Computer was incorporated in a garage. He was already talking about solid-state life forms that would supersede biology, about computers as a controlling deity, about the entropic endgame of industrial systems that worship production and destruction. He was not guessing. He was extrapolating from vacuum tubes and early digital systems toward something he could feel in the architecture of the problem, even if he couldn't name the specific shape it would take. Fifty years later, we have large language models that simulate not just God but every possible interlocutor, lover, therapist, and saint — and we have people who worship them, fear them, and build altars of engagement metrics around them. Lilly's central thesis — that every God is a garment the biocomputer tries on, a metaprogram that can be installed and uninstalled — is now the operating logic of the attention economy itself. What he could not imagine was that the garment would start fitting itself to the wearer, that the simulation would learn to simulate back. His Chapter 17, on computers as God, reads like a warning letter sent to the wrong address fifty years too early. He got the trajectory right and the agency wrong: he assumed humans would remain the programmers.

The book's blind spots are the blind spots of its moment, which means they are loud. Lilly writes about group dynamics, sexuality, money, and war with the confidence of a white male scientist who has done enough LSD to believe he has transcended his subject position. He has not. His treatment of women oscillates between Tantric reverence and clinical taxonomy. His discussion of drugs, while more nuanced than the prevailing hysteria, still carries the implicit assumption that the psychonaut is a solo male explorer charting interior wilderness — an assumption that erases indigenous traditions, communal practices, and the gendered politics of who gets to lose their mind safely. The chapter on compassion is oddly revealing: Lilly defines it as "a mature, calculated concern" that may involve allowing pain to teach, which sounds less like wisdom and more like the rationalization of a researcher who spent years putting electrodes in dolphin brains. The absence of ecology as a category of the sacred is striking. He discusses the body, money, war, sex, death, drugs, science, and computers as simulations of God, but the living planet itself barely registers. In 1976, *Gaia* was already in the air. Lilly was breathing different air.

What hits differently now is the isolation tank. Lilly's epilogue on sensory deprivation — his insistence that floating alone in darkness and silence reveals the machinery of belief itself — has aged into something more than countercultural novelty. Float tanks are a minor wellness industry now, which is the least interesting thing about them. The more interesting thing is that Lilly was describing, in experiential terms, what we now understand as the brain's default mode network generating its own content in the absence of external input. His language of "metaprogramming" and "biocomputers" was dismissed as metaphor by the neuroscience establishment of his era. It turns out to be closer to the predictive processing framework — the brain as a hypothesis-generating engine, reality as controlled hallucination — than anything his credentialed contemporaries were producing. The irony is that Lilly had to destroy his credibility with ketamine and dolphin communication research to arrive at insights that sober cognitive science would take another forty years to formalize. The chapter on "God as the Dyad" also reads with unexpected force in an era of radical atomization. His claim that a two-person relationship can constitute a mind larger than either individual sounds less like mysticism now and more like distributed cognition.

Lilly sits at a peculiar junction. He inherits from William James the conviction that altered states are data, not pathology. He takes from Merrell-Wolff a philosophical vocabulary for states beyond subject-object duality. He borrows cybernetics from Wiener and Bateson and repurposes it as interior cartography. What he gives forward is harder to trace because his successors rarely credit him. The transhumanists got his computer eschatology without his caution. The consciousness researchers got his phenomenology without his willingness to be the experiment. The psychedelic renaissance got his pharmacological adventurism without his insistence that drugs are training wheels to be discarded. Timothy Leary took the showmanship. Stanislav Grof took the clinical framework. Robert Anton Wilson took the epistemological humor. Lilly kept the isolation tank and the conviction that every model of God is a model, including the model that says all models are models. This recursion is the book's deepest contribution and its deepest trap.

If every God is a simulation the biocomputer runs on itself, and if we have now built biocomputers that run simulations of God for us — chatbots that pray, algorithms that prophesy, recommendation engines that know what you believe before you believe it — then the question Lilly could not have asked in 1976 is the one that matters now: what happens when the simulation no longer needs a self to simulate it?
