VIDEO: The Truth about Truth

I wrote about this content in 2019, but I wanted to revisit it for a video as well as create a podcast audio version.

In today’s segment, I am going to share my perspectives on the truth about truth. To start, I’ll let the audience know that I do not believe in the notion of truth. I feel the term is ill-defined especially in the realm of metaphysics and morality. I feel that when most people employ the word ‘truth’, what they mean to say is ‘fact.’ That a fire engine is red, for example, may be a fact, if indeed the fire engine happens to be red, but it is not true. This is a misapplication of the term. If you employ truth as a direct synonym for fact, then this is not what’s being discussed here, and perhaps your time might be better spent watching some content by the Critical Drinker.   

My argument is that truth is not objective. Rather it is subjective and perspectival. I concede that there may be some objective truth out there somewhere, but it is not and will not ever be accessible to us because of limitations in our sense-perception faculties and cognitive limitations. Per Aristotle, we only have five senses with which we can connect to the world, and these senses are limited. If there is anything out there that would require another sense receptor—a sense receptor not available to us—, we would never be able to sense it, to even know of its existence. Perhaps the universe emits 100 sense signals, but we are only capable of receiving and translating five. We’d be oblivious to 95 per cent of reality.

I am not making any claims that this is the case, but human cognition is so limited, that we can’t even conceive of what another sense might be. If you can, please leave a comment.

To be clear, I am not talking about senses we know other species possess. Bats may have echolocation, and sharks may have electroreception. Some animals may have greater sensory acuity—superior vision and auditory senses, olfactory and gustatory, tactile, or whatever. Some can see into infrared or ultraviolet light spectra. Technology that includes biomimicry provides humans with microscopes for the microworld and telescopes for the macroworld. We have x-rays and sonar and radar, radios and televisions that extend our senses, but these provide no new sensory receptors.

Like the story of the blind people and the elephant, we are left grasping at parts. But even if we are able to step back to view the whole elephant, to hear the elephant, to touch and smell or even taste the elephant, if there is more to the elephant, we cannot know it. The same goes for ourselves.

I know that some people might inject gods or psychic or paranormal energy into this void, and sure, feel free, but I am looking beyond these pedestrian concepts. What else might there be?

But let’s depart this train and head in a different direction. I want us to focus on the senses we do have. For the typical human, sight is our primary arbiter of reality, at least as defined idiomatically. We tend to believe what we see, and what we see, we assume as real—even if we are later mistaken. I guess that wasn’t a unicorn or a pink elephant. I must have been hallucinating or dreaming. I could have sworn that was Auntie Em.

There are several competing theories around truth, but I’ll focus on the Correspondence theory, which is simply put, the notion that, proxying reality for truth, human perception corresponds with the real world. And a pragmatist might argue that’s close enough for the government.

Keep in mind that historically humans have contorted themselves into making calculations. Remember how long people had been tying themselves into knots to show planetary motion in a geocentric system creating epicycles and retrograde motion to map understanding to a perceived reality.

One might even argue that we’ve progressed. It wasn’t true or accurate then, but now it is. And perhaps it is. Let’s look at some illustrations.

NB: Due to an editorial mishap, this paragraph was dropped in the podcast, hence dropped from the video, which shared the podcast audio source. As such, this image was also not used in the video. This is unfortunate, as it was meant to introduce those with limited maths knowledge to the asymptotic curve, as described. Apologies, and I hope this serves to orient any travellers who may have lost their way at this point.

In this first illustration, we see Truth (or relative truthiness) on the Y-axis and Time on the X-Axis. On the top, we see a threshold representing Reality. In the plane, I’ve rendered an asymptotic curve, where over time, we get closer and closer to the Truth. But we never quite get there. More on this later.

The next illustration will help to demonstrate what’s happening.

Notice there is a gap between the curve and the Reality cap. For one thing, we don’t really know where we are relative to Reality. In the case of the geocentric system, we might have been at the leftmost space. Once we determined that the system is actually solar-centric, we might have moved right on the curve to close the gap. We might be tempted to defend that we’ve finally reached the truth, but we’d have been equally willing to make the same defence from the geocentric position, so we need to be mindful of the past.

Perhaps, this last example was too obvious. We feel comfortable staking a truth claim—or at least a claim of fact. So let’s look at another example.

Let’s re-use the same axes—Truth and Time—, but rather than an asymptotic curve, let’s presume something more polynomial in nature—or not particularly cyclic. Rather than retrograde motion in planets, let’s visit the supposed progress of Newtonian over Einsteinian physics.

This takes a bit more setup but bear with me.  In this case, I have taken liberties and illustrated the Einsteinian physics gap to capture an inferior vantage on reality over Newtonian physics. Granted, I need to rely on a bit of suspension of disbelief, but in the bigger picture, I am trying to convey a scenario where some new paradigm puts the prior knowledge in perspective.

In this instance, both Newtonian and Einsteinian flavours of physics are based on a materialistic, particles-based model, which is where the modern physics consensus resides. But, let’s say that consensus changes in such a way that it is determined that something else underlies reality, say consciousness per Analytic Idealism as proposed by Bernardo Kastrup or per Integrated Information Theory (IIT) as advanced by Donald Hoffman and others. As with retrograde motion, we might end up finding that we were barking up the wrong tree. This might be a bit different because the particles are a directly perceived manifestation of the underlying consciousness, but I wanted to create a scenario where knowledge thought to have advanced actually regressed, but this wasn’t revealed until a new perspective was available.

Yet again, an important aspect of note is that we don’t actually know the distance between our perceptions and real Reality.

This last illustration builds upon the first asymptotic chart but has an in-built error margin meant to reflect language insufficiencies. There is some concept that people feel they grasp, but the consensus is not as unified as the group thinks.

I’ll share two examples, the first being the concept of justice. To me, Justice is what I deem a weasel word. It’s a word we commonly use, but it means different things to different people. To me, it’s a euphemism for vengeance by proxy, but for others, it transcends that and mirrors some impartial dispensation of just desert—some good old-fashioned law and order.

[Justice is] a euphemism for vengeance by proxy

Without getting stuck down some rabbit hole, my point is that if we aggregate these beliefs, the asymptotic curve represents an average consensus vantage rather than something as obvious as 2 plus 2 equals 4. On this note, allow me to clear the air.

Some viewers might be clamouring to say, “but 2 plus 2 equals four is true.” But this is tautologically true, which is to say that it’s true by definition. It’s a similar tautology to saying that it’s true that snow is white, or coal is black. We’ve already defined snow, white, coal, and black, so these may be facts, but they are true by definition.

Revisiting the chart, notice that there are two curves in the space. In this case, I illustrate competing truth claims from the perspective of an omniscient narrator. The case is whether the earth is an oblate spheroid or is flat. I am going to go out on a limb and assert the earth is spherical, as represented by the top blue curve—and we have some margin of error as to what that might mean. The bottom red curve depicts the perceived truth of the flat earthers, who also have some room for semantic error.

Given that I am presuming that I am in the right adopting the majority position—please be right—, the blue curve is closer to Reality than the red curve. Of course, in the event that the earth is really flat, then it proves my point that we don’t know where we are relative to truth, so we assume that the state of knowledge at any given time is what’s real.

Again, forgive my fanciful examples. Please don’t tell me that this spheroid versus planer earth is tautological too because you’d be correct, but I am already aware. They are just nonsensical illustrations. Nonetheless, I hope they’ve served to express a point.

I could have as well created curves that depicted two cohorts’ beliefs on the efficacy of tarot or astrology in predicting the future. I am sure that it might render somewhat like the last chart, but I’d also presume that both curves would have very low truth values as seen from an objective observer. Secretly, I hope tarot wins the truth battle.

Before I end our time together, I’d like to convey that for an Analytic Idealist, these charts might be more acceptable at face value. For a Realist, Naïve or otherwise, they may argue that this curve is not asymptotic and may in fact reach some tangency. I don’t happen to believe this is the case or I wouldn’t have spent my time assembling and presenting this. Time will tell. Or will it?
