A Simulation from Pure Thought

Several years ago philosopher Nick Bostrom put forward the notion that the universe and everything in it is actually a massive simulation designed by humans living in the distant future. A recent article at Mind Matters discusses an update of Bostrom's original idea.

The Mind Matters article plays off an earlier piece at Big Think by Paul Ratner.
Philosopher Nick Bostrom famously considered this in his seminal paper “Are you living in a computer simulation?,” where he proposed that all of our existence may be just a product of very sophisticated computer simulations ran by advanced beings whose real nature we may never be able to know.

Now a new theory has come along that takes it a step further – what if there are no advanced beings either and everything in “reality” is a self-simulation that generates itself from pure thought?
Bostrom imagined that the universe was physical but that humans in the future had achieved such a high degree of technological prowess that they were able to design computer programs which simulated the world we now inhabit and us as well.
Even the process of evolution itself could just be a mechanism by which the future beings are testing countless processes, purposefully moving humans through levels of biological and technological growth. In this way they also generate the supposed information or history of our world. Ultimately, we wouldn’t know the difference.
The current hypothesis, though, is that the universe is not material at all but is pure thought. It's an "idea" that has somehow generated itself.

The hypothesis takes a non-materialistic approach, saying that everything is information expressed as thought. As such, the universe “self-actualizes” itself into existence, relying on underlying algorithms and a rule they call “the principle of efficient language.”

Under this proposal, the entire simulation of everything in existence is just one “grand thought.”

How would the simulation itself be originated?
It was always there, say the researchers, explaining the concept of “timeless emergentism.” According to this idea, time isn’t there at all. Instead, the all-encompassing thought that is our reality offers a nested semblance of a hierarchical order, full of “sub-thoughts” that reach all the way down the rabbit hole towards the base mathematics and fundamental particles.
Physicist Sir James Jeans anticipated something like this all the way back in 1930 when he wrote that, “The universe looks more and more like a great thought rather than a great machine.”

Denyse O'Leary (under the pen name "News") at Mind Matters points out the significance of this:
The most significant element of this new theory is surely that it is explicitly a theory of “panconsciousness” and non-materialism. Thus it bears comparison with newer theories of consciousness, which are explicitly panpsychist.
Panpsychism is the view that everything in the universe from the largest stars to the tiniest particles are all conscious to one extent or another. Panpsychism has been around for a long time but is becoming more mainstream now because the classical materialism (or physicalism) of the 19th and 20th centuries simply cannot explain many of the phenomena that scientists are observing, especially in quantum mechanics.

O'Leary continues:
However off-the-beaten-track this ... hypothesis may seem, it does solve two problems:

First, it offers an account of consciousness that conforms to what we experience. Materialist accounts generally fail at that. Famously, Darwinian philosopher Daniel Dennett describes consciousness as a user illusion. It’s not really there. Which prompts the question, whose illusion is it then? The [new theory] sees human consciousness as a sub-thought of a grand thought.

Agree or disagree, that is somewhat closer to what we experience.

Second, the researchers’ approach — that the universe simulates itself into existence — gets rid of the problem of infinite regress (what simulated the universe?), in the same way that “In the beginning, God created the heavens and the earth” gets rid of it.

Of course, as noted above, anything that simulates itself into existence as “one grand thought” might as well be God.
What O'Leary is saying is that if consciousness is indeed the ultimate reality, if the universe is a grand thought, if information is the fundamental stuff of the world, then there must be a mind in which the thought resides and which is the source of the information out of which the world is constructed.

That mind must transcend the universe of space, time and matter and it must also possess unimaginable knowledge and power. Indeed, as O'Leary states it would seem to be almost indistinguishable from God.

The more science discovers about the world, the more untenable the old naturalistic materialism of the last two centuries seems to be and the more compelling is the conclusion that God, or something very much like God, has created the universe and is holding it all together.
