Timothy asks:

“Are we in a simulation?”

Though it is not strictly a logical approach to ask a philosophical question by reflecting on a feeling I do feel it helps to add meaning and perspective for the question. I wanted to ask what are the chances that we are living in a simulation. One reason I ask this is because of the infinitely unlikely possibility when looked at scientifically that I would ever be alive and yet less to be a human and in the era I could write this. Either this is like winning the lottery 1 million times in a row or something else is at work that I am alive, as a human (my opinion the best thing to be), in this era with all this technology. Thoughts?

Answer by Craig Skinner

Wonder at your existence, worry that you might be a simulant. Two philosophically interesting thoughts in one question. Also, it’s just fine if a question arises from a feeling.

Yes, your (or my, or my cat’s, or the squirrel in my garden’s) existence was hugely improbable. Had a different sperm out of the millions competing to penetrate the ovum been successful, had your father been away on business on the day you were conceived, you wouldnt exist. Also the huge fluke that your parents chose to mate with each other rather than with one of the many alternatives. And it’s mind boggling to think that not a single one of your millions of forebears over 3 billion years failed to reproduce. If just one of your myriad fishy ancestors had been eaten by a bigger fish when young, no you. And yes it is like a lottery. Just as somebody has to win however tiny the odds of success, so, given that you exist, you must be somebody, and somebody has to be you.

As to whether you (and I) are simulants, the answer is it’s a distinct possibility but it’s difficult to assign a probability. We assume there is a real world with intelligent beings in it. And your question is whether you could be a simulated being in a simulated world created by these real beings  who run the simulation on their supercomputers.

Clearly such technology is beyond current human capabilities. But given the pace of developments in computing and AI,  it may be  that future superintelligences, either augmented humans, or maybe more likely nonhuman following the singularity of the development of  smarter-than-us AIs which rapidly engineer ever-smarter successors  to reach unimaginable levels of intelligence.

And so the probability you seek depends on:

  1. Whether superintelligences will arise.
  2. Whether they would be interested in simulating earlier eras of human life (say as a game or for historical research), rather than ignoring or eliminating humans.
  3. Whether such simulations would be frequent (like our computer games played in most households).
  4. Whether simulated humans would be genuinely conscious (like you and me).

If the answers to these four questions are all yes, and they might be, then right now it’s far more likely that we exist in a future simulation than that we live in the real world in the 21st century.

So, in case we do, let’s tell the Simulater that we’re on to it:

Hey there BIGBRAIN, we know you’re there. And in case you had doubts, yes we are aware, we love, laugh, cry and care about our little lives down here. And dont get too smug up there in your real world, for you and your world could themselves just be simulations by yet higher orders of intelligence in the proper real world. Or maybe it’s simulations, rather than turtles, all the way.

Philip asked:

Is it possible that our innate sense of self, our egocentric outlook on the world, could be wrong? After all, our brains are never REALLY connected; so we cannot know for sure that our consciousness is REALLY separated by anything else than space and time. What I mean is; Is it possible that there could be only a single universal consciousness of which we are all a part? Could this REALLY be how it is? Or are there any philosophical arguments against this view? I haven’t been myself since I first had this thought and I’m dying for an answer. On the one hand it feels exhilarating, on the other hand it kinda kills one’s self image. What do you people think?

Answer by Geoffrey Klempner

It may not be obvious that these two questions are connected, but I immediately thought of the philosopher Arnold Zuboff. I first met Arnold back around 1974-5, when he gave a paper at Birkbeck College Philosophy Society. As President for that year, it was my duty to entertain invited guests at a local restaurant. Over dinner, he hit me with this question: How unlikely is it that I ever came into existence?

The question seems to smash science into a pile of rubble. There is something science cannot explain, why I am in the world. However, that’s not Zuboff’s view at all. A few months ago, I came across Arnold’s YouTube video, Finding Myself — And Undoing the Fear of Death as Annihilation. (The video is over two hours long so you might want to make some sandwiches.)

In his presentation, Zuboff argues from science — or, rather, from a materialist view of the brain and its relation to consciousness — to the remarkable conclusion that there is only ONE subject, who is you, me, and every other conscious being in the universe.

As Philip says, ‘a single universal consciousness of which we are all part’. This is actually a view put forward, more or less tentatively, by Thomas Nagel in The View From Nowhere. It’s really just a way of looking at the ‘I’ question. The statement ‘I am TN’ when uttered by TN, or the statement ‘I am GK’ when uttered by GK, are both true and non-tautological, because the ‘I’ in each case refers to a singular entity Nagel calls the ‘Objective Self’.

The million-dollar question is what exactly this means. If it’s just a way of looking at the self and consciousness, then nothing is implied about the actual world that we don’t already know. Human beings are separate individuals, just as before. In other words, we’re just talking about a way of assimilating the consequences of materialism, getting comfortable with the idea. However, as an argument against the fear of death — which is what Arnold wants this to be — I don’t feel the least bit comforted by the thought that human life will go on after my material body perishes. I just don’t see the thing that Arnold ‘sees’.

On the other hand, if all this is just a simulation, if the entities of physics are not the ultimate reality but merely, say, patterns on an alien mega-computer chip or hard drive, then that puts a whole different complexion on things. I could be the one singular consciousness playing the ‘video game’ of human life, pretending to be, first, one particular person, then another particular person, then another. In the words of Alan Watts (whom I’ve quoted far too many times) ‘We are all It’. The singular entity, according to Hindu philosophy as articulated in the Upanishads, plays the game of forgetting who It is, and pretending to be you, me and everyone else.

I get it. We’ve all experienced what it’s like to remember something you had forgotten. Imagine if all these lost memories came flooding back at once. You would know that you were not who you thought you were, an ‘ego in a bag of skin’ (Watts The Book: On the Taboo Against Knowing Who You Are) but rather everyone. But I don’t believe that either. What problem would it solve? And wouldn’t the inevitable consequence be that I was, after all, alone in the universe? Just pretending to be a person in relation to other persons? How sad would that be!

For now, I prefer to think that, yes, it is a remarkable fact that I exist, but this isn’t necessarily the same ‘remarkable fact’ as the fact that GK exists. I don’t know what are the conditions for the existence or non-existence of the thing I am now calling ‘I’. Maybe, if GK hadn’t existed, I would be someone else, or maybe not. That’s all one can say until we have more to go on.

Philo asked:

Does the following successfully establish a presumption of strong global atheism?

“Define strong global atheism as the view that there is no god. There is a presumption of strong global atheism because theists propose the addition of a supernatural entity (a god) to what is already known to exist (the natural world). That is, theists make an extraordinary claim, and extraordinary claims require extraordinary evidence. In the absence of such evidence, strong global atheism is warranted.”

Answer by Gershon Velvel

As a would-be atheist, I am the first to admit that there is a lot of stuff I don’t know. To paraphrase a remark I heard somewhere, ‘there are unknown unknowns’. It’s bad enough not knowing stuff, worse when you’re not even able to form a conception of the kind of thing that might be missing from your inventory of knowledge.

Not knowing what I don’t know in relation to the God question, I feel somewhat queasy about any argument based on evidence or the lack of it. By saying that ‘evidence is required’, you are issuing a challenge, a challenge you believe cannot be met. But you are leaving the larger claim completely unchallenged: the claim that the God-hypothesis makes some sort of sense. If it didn’t make sense, how do you even know what you are talking about?

First of all, we need to explore a relative side issue. Does the claim that some ‘supernatural entity’ exists require ‘extraordinary evidence’?

It depends. The supernatural entity in question might be rather small and localized: a poltergeist, for example. Admittedly, if someone makes the claim that they have a poltergeist in their home, you are going to want to sift the evidence very carefully indeed. But if you are in the living room, with all your fancy electronic equipment, and objects start flying across the room for no reason at all, there comes a point where you have to say that the evidence of something matching the description of ‘poltergeist’ is overwhelming.

Is this likely to happen? I don’t believe so. David Hume in his Dialogues Concerning Natural Religion makes the point that even with seemingly ‘overwhelming evidence’ you have to consider the balance of probability: the chance that science is fundamentally flawed, and the natural world is not all there is, versus the chance that someone has played a very clever trick or that you’re having a hallucination, or whatever. But then again, if poltergeists became a regular occurrence, that argument would start looking rather thin.

Back to God. There is a case for saying that the flaw in the evidential argument gives the theist all they need. If you allow that the notion of God as a supernatural entity makes sense, then you have to allow that there is some possible world (I mean logically possible not ‘nomologically possible’) in which God exists. God isn’t just some very powerful supernatural being. (That would be the Devil.) God is a necessary being. So far as anyone existing in that logically possible world — call it the God-world — is concerned, God exists in ‘all possible worlds’. By a simple application of modal logic, if God exists as a necessary being in some possible world, then God exists in all possible worlds. Ergo, God exists.

I’ve just offered a version of St Anselm’s ontological argument updated with contemporary possible world semantics. As it stands it sounds pretty convincing, doesn’t it? Intuitively, it just seems a mistake to concede that much to the theist. Then again, maybe you could resist the argument by tweaking your modal logic so that ‘all possible worlds’ means something different in different possible worlds (look up ‘possible worlds’ and ‘accessibility relations’) but that looks like desperation to me.
