The tricky thing with nothing is that it can’t be experienced. It seems simple enough. Most of my readers will agree that consciousness is emergent of neurochemistry, so when the brain dies, so too does conscious experience, and there is nothing left in its place. It’s not so hard to imagine. You need only think of how life was before you were conceived. Only, there is a problem.
The problem is best summarised thusly: there is no such thing as nothing. By definition. Whereas our worlds are made up precisely of what is experienced.
A ludicrous supposition? You are welcome to think so, but if you do, kindly drop a comment in the box below explaining why. This is a concept I’ve been struggling with, clumsily, in the two months I’ve been away from Viridian Circles, and I welcome any simple solution.
Before you do, though, consider the age-old paradox of Theseus. If you have never heard of it, sail on his hypothetical ship a while and ponder the folly of identity:
“The ship wherein Theseus and the youth of Athens returned had thirty oars, and was preserved by the Athenians down even to the time of Demetrius Phalereus, for they took away the old planks as they decayed, putting in new and stronger timber in their place, insomuch that this ship became a standing example among the philosophers, for the logical question of things that grow; one side holding that the ship remained the same, and the other contending that it was not the same.” – Plutarch
More pertinent: are you exactly the same person who existed ten years ago? Are you a different person altogether? At a cellular level, almost every component of your body has been replaced several times over throughout your lifetime. Down to the level of atoms, sub-atomic particles and quantum waves, the fluctuation is similar but more rapid. Being inextricably linked to the body, the mind has also changed. You don’t think the same way as when you were ten years old, or twenty, nor do you have the same emotional patterns, or desires, or aspirations. Your self-image is altered. Your beliefs have changed. Oh you may be similar to these past versions of you, linked as you are by memory on various level of awareness, but you are not the same person. If you were, you would be frozen in time, because motion implies change.
The change in body and mind over years is great, whereas the change over seconds is not noticeable, but the difference is only a matter of scale. In either case, you are changing. By every smallest increment of time, you are transforming into something related, but different. And every time this happens – and, I should add, it happens an infinite number of times, since the present moment is irreducible to any unit and is instead a constant meeting of past and future – you die.
That is, you cease to exist.
That ten-year-old version of you does not experience this reality any more than the twelve-year-old version, or the fourteen-year-old, sixteen, etc. The past is only an idea, a memory. It has no present existence. The only present existence is your own, right now. And if this non-existent vacuum applies to long-past versions of you, then it must also apply to more recent versions. Ten minutes ago, ten seconds, a nanosecond. Every time, ‘you’ have been replaced with a slightly different copy, subtly altered neurochemistry, different spacetime coordinates. And each time, ‘you’ have ceased to exist. Yet experience continues on.
This is because, as I said before, experience is an emergent process of the brain. In this instant, your brain processes memories that keep your experience here on Earth constant and consistent. Your identity complex, short-term tasks and temporal perceptions are all resultant processes of the brain and nervous system, and every quantum version of you is linked to every other version via these processes. This all adds up to the appearance of a consistent lifetime.
Now to validate the paradox.
When you die, when the brain shuts down for good, all these processes cease and in their place, there is nothing. Why, then, does the constant stream of non-existence behind and before you not dominate your current experience? That is: you cease to exist moment to moment, so why doesn’t it stay that way?
But didn’t I already explain why? Consciousness is an emergent process of the brain, and memory makes the experience consistent. Okay, then consider this.
Suppose a hyper-advanced being decides it wants to transmute all the brain functions that make you you, into mine. In an instant your memory and identity are gone, and in their place is mine. So you are dead. In your stead, I experience, pain and pleasure, emotions and thoughts; in short, my own qualia. For you there can be no more of those things. For you there is nothing left at all.
But I reiterate: this is exactly what’s happening in every single moment. It’s just that it’s less extreme. You are being replaced by slightly altered copies, and yet you go on experiencing. Why? Because there is no such thing as nothing.
Non-existence cannot be experienced. There will always be conscious experience in its place. It’s a matter of definition.
Ever been under anaesthetic? One moment you were on the operating table, the next you were waking up groggily hours later. To you, there was no in between. The thoughtless nothing of that time cannot be experienced, because there is nothing to experience.
Likewise, you cannot travel ‘outside’ the universe, because there is nothing outside of existence to traverse. As in physical outer space, so too in experiential inner space.
There will always be experience, because there is nothing else.
Death may entail non-existence. But every single moment is death. Yet there you are all the same, existing. Well done, your qualia just broke the universe.
How do we reconcile this paradox? I have several possible solutions, but first, I would hear yours. Leave a comment with your thoughts, and I’ll follow up with mine in the next entry.
