In 2003, an Oxford philosopher named Nick Bostrom published a short paper asking whether we live inside a computer simulation. It became that rarest of things, a philosophy paper with a fan base. Tech founders cite it on stage, physicists argue about testing it, and one billionaire famously put the odds that we inhabit “base reality” at one in billions.
Here’s what almost never comes up in those conversations. Mystics in the early centuries of Christianity mapped this territory already, fabricated world and all. And they went further than the modern version does, because they left instructions for what to do about it.
Bostrom’s Argument
Bostrom’s paper doesn’t actually claim we’re simulated. It argues that at least one of three statements must be true, and it lets you pick.
Either civilizations destroy themselves before gaining the computing power to simulate their ancestors. Or they gain that power and choose never to use it. Or simulated minds vastly outnumber biological ones, in which case a mind selected at random, yours for instance, is probably one of the simulated ones.
That’s the whole machine. No pink lasers, no glitching cats, just an uncomfortable bit of probability. Which is exactly why it spread, because nobody could dismiss it as mysticism.
The Second-Century Version
The Gnostics scandalized their neighbors with a claim that sounds familiar now. The world we live in is a construction, and they meant that physically, not as a commentary on society. In their telling, the cosmos was assembled by a lesser maker copying originals he barely understood. We’ve written about that blind craftsman before.
Above his construction sits the world he copied, a fullness of reality he cannot perceive. Below it, us. And inside each human being, these teachers insisted, there burns a fragment that was never manufactured here at all.
Read Bostrom next to the Apocryphon of John and the parallels line up almost mechanically. A made world. A maker who is mighty inside his creation and minor outside it, the way a programmer is a god to the program and a commuter to everyone else. Inhabitants who never suspect, and one decisive variable dividing them: whether or not they know the situation.
Philip K. Dick noticed the match half a century ago and built his late work on it. He proposed a computer-programmed reality in a 1977 speech, back before the idea had any equations attached.
Where the Stories Diverge
If the mapping were exact, the simulation hypothesis would just be Gnosticism with worse poetry. The differences are where things get interesting, and three of them matter.
You. In the simulation story, you are simulation all the way down. Every memory, every preference, the whole self is generated by the system, so there is no “you” that could ever leave it. The Gnostics claimed the opposite. Something in you predates the construction and doesn’t belong to it, which is the only reason waking up is worth anything. A character can’t exit the game. A trapped player can.
The mood. Simulation talk tends to land in one of two places, paranoia or shrug. Either nothing is trustworthy or nothing matters, and both moods excuse you from your neighbor. The Gnostic version lands somewhere else. If everyone around you carries a sleeping spark, a fabricated world becomes a reason for more compassion, not less. Nobody in the ancient texts is an NPC.
The exit. Here the difference is sharpest. The simulation hypothesis offers no way out, even in principle. The Gnostic exit, read carefully, was never a jailbreak through the walls either. When the disciples asked when the new world would arrive, the Gospel of Thomas records an answer pointing the other way:
“The Kingdom of the Father is spread out upon the earth, and people do not see it.”
The other world is not somewhere else. It’s this one, perceived without the filters, a teaching we’ve explored on its own. The escape was always a change in seeing.
What to Do Inside a Possibly Fabricated World
You can’t test your way out of Bostrom’s trilemma, and you can’t verify the fullness. What you can do is use the question well. In practice, that looks like this.
Downgrade the theory, keep the insight. Whether the universe is simulated sits beyond your reach. Whether your corner of it is fabricated does not. The feed you scroll, the storefront arranged around your data, the outrage cycle timed to your attention span: these are constructed environments with makers and motives. Spend your suspicion there, where it pays.
Refuse the NPC move. The moment a worldview lets you demote other people to background characters, something in it has gone rotten. Treat everyone you meet as though they carry the same light you do. The ancient teachers considered that non-negotiable, and it’s the best protection against the ugliness simulation talk sometimes breeds.
Practice seeing instead of speculating. Arguing about the walls of the world changes nothing. Attention does. Take one ordinary thing each day, a meal, a face, ten minutes of sky, and give it your undivided attention for a moment. A kingdom spread out upon the earth is only visible to people who look.
Let the stakes stay high. The tempting response to “it might all be fake” is to care less. Both traditions block that move. Simulated or not, pain still hurts and kindness still reaches people, and in the Gnostic account your conduct is precisely how the spark wakes or stays asleep. Fabricated scenery has never made a single choice weightless.
The Part the Paper Leaves Out
After all the mapping, the two versions come apart on one point, and it’s the decisive one.
The modern argument tells you the world might be fabricated, and then it’s finished with you. Nothing follows. The ancient version starts there, on page one, and spends its entire literature on the question that comes next. Given the situation, how does a person wake up?
The billionaires are still arguing about the odds. The mystics skipped ahead.
Bostrom’s paper, “Are You Living in a Computer Simulation?”, appeared in Philosophical Quarterly in 2003. The Gospel of Thomas and the Apocryphon of John are available in translation in The Nag Hammadi Scriptures (Marvin Meyer, ed.).
