We all have a solipsistic experience nightly, when we sleep and dream. Each night we inhabit a universe which seems to us, convincingly at the time, to have a wealth of external people and places in it. But all of those people and places are created inside our brains solely for the benefit of the dreamer. In the modern world, however, we can place an additional, familiar experience of a solipsistic reality next to that of the dream: the single-player video game.
One of the first things people discovered when modern computing became a reality is that it’s relatively easy to simulate laws of physics, representing aspects of the real world. This theoretically enables an approach to simulation that builds an entire universe from basic building blocks. A quark could be a tiny bit of fundamental matter (whatever that might be), but it could just as easily be a rule programmed into a computer—or perhaps even a coherent thought in the mind of an all-powerful intellect.
In the year 1999 CE, just on the cusp of a new millennium, the then Wachowski Brothers released “The Matrix,” one of the most influential, imitated, and widely discussed movies of its times. It was only four years later, in 2003 CE, that philosopher Nick Bostrom of Oxford University introduced an argument that it is not only possible we are living inside a computer simulation, it is actually significantly likely. Although it may have sounded like a high-concept science-fiction thriller, the argument drew upon well-established lines of logic and a widely held series of assumptions.
Did Nick Bostrom, professor of philosophy at Oxford University, provide the first convincing modern proof of the probable existence of God? At first glance it seems more than unlikely. Bostrom—best known for his notorious theory that the world exists only on a giant computer—isn’t a notably religious man. What’s more, philosophers and theologians have argued for thousands of years whether God exists; whether the existence of God can be proven; and whether demonstrating proof of God’s existence is something we should even try to pursue. Despite all this, in the year 2003, when Bostrom published a new theory detailing the strong probability that God does in fact exist, nobody noticed (except David Pearce).
