In Simulation

The new Matrix film is nearly upon us, and so my partner and I are watching all the previous films and supplementary material. An important part of this process is discussing the films after viewing, sharing the various revelations we have that we may have missed on previous viewings. It speaks to the quality of the original story that we continue having revelations and epiphanies even 20 years later.

My latest revelation is one that is raising some rather disturbing questions regarding the story and regarding how consciousness operates in our real world. I might even suggest it is a weakness in my previous arguments regarding consciousness thus far. The issue of what it means to be “in simulation.”

Of course, before I can even talk about being “in simulation,” I will have to discuss what a simulation is. As it turns out, trying to elucidate the idea of a simulation caused a rather heated debate between my partner and I. We cannot agree what a simulation is. And so, in this post, I will be primarily focused on my interpretation. I will try to share her interpretation, but the honest truth is that I don’t really understand her interpretation.

I have spoken before about identity and of the world. My identity is what I (and others) consider to be what constitutes me. The “I” when I say I. In some sense, my identity is what separates what is me from the rest of the world, and from others. Which brings us to the idea of the world. The world is that which is not me, and very generally what is not others. You are not the world, but you are a part of the world, just as I am a part of the world as well.

However, the world also includes that which is not a part of you or me. The world, in some sense, can exist without either of us. The world (we generally believe) can and will persist even when I cease to exist. Furthermore, the world contains objects that both you and I can observe and generally agree upon. We can both see the same objects, albeit from slightly different perspectives. And so, very generally, the world is the same for me as it is for you. At least, this is a significant assumption I make about the world. And I believe most people make a very similar assumption, even if they are not aware they are making this assumption.

A simulation is also a world, though not the “real” world. The world we presently inhabit, I believe, most will agree is considered to be the “real” world. This blog, this website, is a part of the “real” world. This blog is not necessarily a part of a simulation. Having said all this, I will acknowledge that as I continue this discussion, questions may be raised regarding the integrity of this.

A simulation is loosely based on the “real” world, and will be a lesser version of it. That is, a simulation will bear some resemblance to the “real” world in some way, and may even share some elements of it. However, a simulation will always be absent some of the elements of the “real” world as well. This is a large reason we will call it a simulation. A simulation, in some sense, is a straw man argument of the “real” world.

Like the “real” world, a simulation is governed by rules and laws. Or, as my partner has pointed out, perhaps not so much governed by as perhaps explained by. For example, in the “real” world there appears to be some sort of attractive force that acts upon all bodies. We often refer to this force as gravity. We even have various mathematical formulas we use to predict how gravity will affect various bodies, and we use science in order to validate these formulas as best we can. Gravity is a sort of governing rule of the “real” world.

A simulation can include gravity, though it does not necessarily have to. The rules of the simulation may be similar to the rules of the “real” world, or they may be vastly different. What both the simulation and the “real” world share is the fact that there are these rules or laws. Navigating a simulation can be done in a similar fashion to navigating in the “real” world; an understanding of these rules is what is required. If I understand how gravity operates (at least on some rudimentary level), then I can navigate through a world governed by gravity.

The point of all this pedantic examination is that a simulation will bear some resemblance to the “real” world. In the case of the Matrix from the films, the Matrix is a simulation that bears a lot of similarities to the “real” world. However, as the character Mouse points out in the first film, it is possible the machines (who created the simulation of the Matrix) could have either accidentally or intentionally made errors:

“How did the machines really know what Tasty Wheat tasted like. huh?. Maybe they got it wrong. Maybe what I think Tasty Wheat tasted like actually tasted like oatmeal or tuna fish. That makes you wonder about a lot of things. You take chicken for example, maybe they couldn’t figure out what to make chicken taste like, which is why chicken tastes like everything.”

While the machines may have correctly or incorrectly represented Tasty Wheat or chicken, the point is that these humans who are now discussing what their “single cell protein combined with synthetic aminos, vitamins, and minerals” actually tastes like are basing their assessment on information they have received from a simulated reality that they acknowledge may have provided them misinformation. In the end, in truth, they have no idea what their meal tastes like, only that it has a taste.

This is one of the critical issues with the idea of simulation and of simulacra. The information we receive from our interactions with any particular world are what we use to recognize and understand the elements of that world. This is the heart of the arguments made by the Empiricists of the 18th century; that all knowledge is based on experience. What they may not have concerned themselves with as much is the reliability of the world that provided them that experience.

Which brings us to the heart of my own discussion here. What does it mean to be “in simulation?” More specifically, what is happening when we are in simulation? In the story, when someone is in the Matrix, does their mind or consciousness or soul leave their body and exist within the Matrix? Or does their mind remain within their body, and the simulation is simply altering the interface one has with their world, hijacking their senses and replacing those experiences with alternate ones?

As I write these words, it seems obvious what the answer ought to be. In the case of the film, as seems to be presented, human minds exist in human bodies, and connecting to the Matrix does not somehow separate the two. A physical cable is connected to the brain stem, and all the sensory input normally fed to the brain by the rest of the body is replaced by alternative sensory information provided by the simulation. Morpheus rightly inquires: “What is real? How do you define real? If you’re talking about what you can feel, what you can smell, what you can taste and see, then real is simply electrical signals interpreted by your brain.” It does not matter the source of those signals, the brain will interpret whatever signals it receives.

The problem raised by the story is that if all of your senses have been hijacked, then you might not be aware that the world you think you are in is in fact a fabrication. You might be in simulation, and not know it. The issue my partner and I debated was whether one could be in simulation and still know they were in simulation.

The manner in which our debate manifested raised an even more insidious issue: where does one’s mind or consciousness reside while in simulation? For me, it seemed obvious: the mind continues to reside where it always seems to reside, in the body in the “real” world. However my partner did not agree. For her, while in simulation, the mind or consciousness left the body and resided in the simulation itself, inside the simulated body. Which case is true can have significant ramifications on events that follow.

As Morpheus suggests, the body cannot live without the mind. Therefore, the mind must necessarily remain within the body at all times, lest the body die. If this is true, then the mind remains in the body in the “real” world. But if this is how it works, then why would unplugging the cable that connects the physical body to the Matrix cause anything bad to happen? How did Apoc and Switch die? If the mind is always in the body, then disconnecting a cable should cause no issues for the individual, as their mind and body remain intact. Only the connection to the simulation is severed, which would seem to merely end the simulation for the individual. They should have simply woken like from a dream.

The alternative is equally problematic. If the mind in fact does leave the body and enter the Matrix, then the body is without a mind and ought to expire. Clearly, within the story, this does not happen. So if minds can successfully be separated from bodies, then Morpheus must be mistaken. Bodies can exist and continue without minds, perhaps on some sort of life support. However, if this is now the case, then how does anything that happens with the mind while it is disconnected from the body affect the body. How can the mind make real such things as injuries?

My partner and I did come up with another alternative that could explain what is going on. What if the mind does not entirely leave the body? What if the mind is sort of tethered to the body, so that a part of the mind remains with the body but a part of the mind enters the Matrix? This would resolve a number of issues, including how the mind makes things real for the body. This tether is what is maintained through the physical cabling that is connected to the brain stem. Severing the tether would be akin to lobotomy, which could then be severe enough to end a person’s life.

In some fashion, the mind is in both places at the same time. Both in the “real” world and at the same time in simulation. If we think of the mind in the “real” world and the mind in simulation as being two parts, then they could be considered connected like in quantum entanglement. I admit, this sort of view of the mind seems incredibly unsatisfying for me. It reminds me of René Descartes’s pineal gland.

In our “real” world, we really have very little understanding of minds or consciousnesses. What we can suggest is that minds and consciousnesses are very unlike bodies or other physical objects. One cannot crack open someone’s head and look at their thoughts. In fact, if you consider how a closed-circuit television (CCTV) system operates, there is nothing that guarantees that the mind exists within a body at all. The mind and consciousness could exist elsewhere entirely. Only the apparent localization created by the position of the various sensory inputs suggests that the mind ought to exist within the physical body.

Without the ability to experience what others experience, I cannot say much about experiences other than my own. What I can say is that when I have dreamed, I have had dreams where I was convinced that the reality of the dream was the “real” world. Only after I awoke from those dreams did I realize my error, and then acknowledged that the dream was in fact a dream and not real. I have also been so immersed in various experiences, such a watching a very engrossing film or a very intense video game, that I momentarily forgot that the world of the immersion was not the same as the “real” world.

In every case (so far) I can say that once I finished or left the simulation, I realized that it was a simulation. Once I had escaped, I felt that I knew with confidence what was “real.” But that only really suggests one thing: that in order to know that something is not real, I have to leave it into something that is more real. In other words, the only reason I have to suggest this is the real world presently is that I have not yet experiences a more real world.
