Embodied Realism Part II: Embodied Truth

Let us continue our series of posts reviewing the philosophy of embodied realism as promulgated in the book Philosophy in the Flesh. In our last post we discovered that embodied realism claimed that, due to our levels of embodiment, the correspondence theory of truth could no longer be upheld. However, we came to realize that this assertion rested on mischaracterizations, misunderstandings, and poor epistemology. Nevertheless, embodied realism has another dog in the fight against classical realism and the correspondence theory of truth, namely, that of embodied truth.

Before I explicate what exactly the tenets are of embodied truth, I want to survey a quote about truth that the authors make:

Any truth must be in a humanly conceptualized and understandable form if it is to be a truth for us. If it’s not a truth for us, how can we make sense of its being a truth at all? (p. 106)

 This is quite strange. The authors are question-beggingly assuming that there are truths “for us.” But this is not something a classicist would concede. The proposition “the earth is round” is true regardless of how we conceptualize and understand it. In fact, said proposition in no way relies on human cognition in order to ground its truth. That is to say, the earth is round whether or not there is anyone around to contemplate its being round. So what is this talk of “truth for us?” You see, the authors are trying to sneak embodiment through the back door here. They seem to think that embodied cognition forces us to admit of truth as somehow being tied to that embodiment. But this only begs the question of what truth is in the first place!

Basically the authors are putting the cart before the horse. They’re trying to define truth in light of their idiosyncratic scientific “results” of embodied cognition. But before one can even embark in scientific investigation one already needs a theory of what truth is! So, the authors have their philosophy backwards, and thus it’s no wonder that their theories lead to such contradictory conclusions—we’ll see this claim come to fruition in future posts.

Now let us keep those remarks in mind and see what the author’s main theory of embodied truth is:

 A person takes a sentence as “true” of a situation if what he or she understands the sentence to be expressing accords with what he or she understand the situation to be. (p. 106)

 Before we even delve into the manifold problems with this, there’s one important thing the reader should understand. The authors here are explicating why a person identifies a statement to be true. But the problem here is that nowhere is it articulated regarding what truth actually is. To simply explain why a person recognizes a statement as true is all well and good, but it is not any type of theory of truth in and of itself—that is to say, what a person takes to be true is not the same as what truth actually is. The point here is that embodied realism has attempted to throw the correspondence theory of truth under the bus, yet it fails to give any competing theory to put in its place.  

Now that that’s been said, we can dissect this “theory” of embodied truth on its own terms. So, this theory seems to entail that a statement is true if what the statement expresses accords (corresponds?) with what a certain individual understands a certain state of affairs to be—isn’t this just a relativized version of the correspondence theory? The consequences of this theory are readily apparent. To run with the example above, we currently believe the earth to be round and spherical. Yet there once was a time when individuals believed the earth to be flat. Now obviously the two statements “the earth is round” and “the earth is flat” are mutually exclusive. Yet, on embodied truth they can both be true. Why? Because the individuals who affirmed the flatness of earth took the sentence “the earth is flat” to accord with what they understood the situation to be.

We see, then, that embodied truth is simply a form of relativism. In fact, the authors admit such: “Embodied truth is not, of course, absolute objective truth. It accords with how people use the word true, namely, relative to understanding (p. 107).” But the authors don’t see this as a problem, because while their truth isn’t objective, it isn’t purely subjective either: “Embodied truth is also not purely subjective truth. Embodiment keeps it from being purely subjective. Because we all have pretty much the same embodied basic-level and spatial-relations concepts, there will be an enormous range of shared ‘truths’ (p.107) [.]” Uh, what? So, truth isn’t objective, but it isn’t subjective either. Apparently there’s a third choice between the two that we’ve missed, despite this violating the laws of logic—those are just metaphorical don’t you know?

Now the fact that the authors are trying to wiggle a middle option between objectivity and subjectivity isn’t even the most laughable problem here. No. The most laughable problem is that they actually haven’t avoided the subjectivity of their theory of truth like they think they have. For they claim that since, as humans, we are embodied therefore we share our embodied concepts with each other. Um, ok, but this does not absolve their theory of truth from pure subjectivity. Remember that something is subjective if it relates to or is dependent on a person’s mind. And this is precisely what embodiment entails! In fact because it is embodied truth, this places it nice and neatly in the category of subjectivity. So far from embodied truth moving away from subjectivity, it is as subjective as one can get.

This obviously has drastic consequences for embodied truth, the most obvious consequence, while likewise being the most damaging, being that it’s self-refuting. You see, if truth is subjective and relative, then one cannot claim superiority of one truth claim over another. That is, one cannot say “X is objectively true,” rather they can only be say that X is true for them, but possibly not for you. Nor can they say that any truths existed prior to or in the absence of humans.

But why is this self-refuting? Well, keep in mind that embodied truth, and embodied realism, are philosophies and theories in and of themselves. That is, they make specific claims about what obtains in reality and how it obtains—if they didn’t then they need not be heeded. But this means that these theories are saying quite specifically “X is the case,” which doesn’t mean “only relative to me, or us, X is the case” but rather “X is the way the world works, period.” Yet how can this be if truth is relative and subjective? That is, how can they say that embodied realism is true, and metaphysical realism is false? Or how can they say that the correspondence theory is false, and embodied truth is true? Well, they cannot, and thus they cannot uphold the objective validity of their own worldview, which amounts to a contradiction.

Such is the philosophical wreckage of embodied realism.

Model-Dependent Realism revisited

Awhile back I wrote a post on Model-Dependent Realism—the view that we form models of the world through our sense datum, but that these models cannot be said to be real or true—attempting to demonstrate why I found it to be untenable. Mike D over at The A-unicornist—my favorite atheist blog to frequent--has since written his own post devoted to demonstrating 1) how I have supposedly misunderstood MDR and 2) how nothing I said actually refutes it. I do in fact disagree (surprise!) with Mike’s assessment of my comprehension and my arguments, and thus this post has manifest. Let’s see what Mike has to say:

MDR does not claim that models "conform to reality" at all; it summarily rejects the idea of an absolute reality to which we have unfettered access — this means we cannot, in principle, know whether a model "conforms to reality". Rather, it claims that our very concept of what reality is is contingent upon our ability to construct models and test them against observation. We assign the term "real" to concepts that allow us to successfully model and predict the world around us.

First, I never claimed that MDR stated that models conform to reality—in fact this is my point of contention with MDR! I agree that MDR states that our models are only interpretive structures, so to speak.

Yet this is, as I demonstrated in the first post, where MDR runs into problems. For unless one is a solipsist then one does have to admit of an objective reality (for even the sense datum that help form our models must come from somewhere outside of ourselves); and sure enough this is what Mike does: “Of course most philosophers and scientists (including Hawking) operate on the provisional, inductively-derived assumption that an absolute reality does exist.” So, since an objective reality must exist, yet on MDR we cannot have direct access to this reality, then the only warranted claim MDR can make is that we simply cannot determine which model conforms to reality—not that no models conform to reality, or that conformation with reality is meaningless. For if objective reality exists, then certain things can be predicated of it, and certain things cannot. But for MDR to state that nothing at all can conform to reality, or that talk of models conforming to reality is meaningless, is to refute oneself, since this assertion itself is a claim about the nature of reality. And this is one fact that Mike never addressed. The point is that MDR essentially claims the following: No model or theory is real, except, you know, the theory of MDR.

Mike continues:

Steven has fundamentally misunderstood what MDR means in saying that no model can be said to be more 'real' than any other; it is simply saying that different 'frames of reference', such as the neural and cognitive models of the mind, overlap and converge to form our picture of reality, even though they may in some ways be semantically or theoretically incompatible (that is, no one frame of reference can fully explain all phenomena).

On the contrary, I maintain that Mike has misunderstood MDR here. For when Hawking was discussing his theory that one model cannot be more real than another, he uses a very specific and revealing example—namely, that of creationism and the Big Bang theory. Examine this quote straight from the horse’s mouth: “this model—the big bang theory—is more useful than [creationism]. Still, neither model can be said to be more real than the other.” Did you catch that? The big bang cannot be said to be more real than creationism! Herein lies the absurdity of MDR. Again, remember that Hawking is not claiming that we can’t determine which theory accurately conforms to reality, rather neither theory conforms to reality at all, since conformity with reality is meaningless.

To demonstrate the absurdity of this line of thought in my first post, I contrasted, as an example, two theories (“models”) of reality: realism and solipsism. I argued that on MDR “neither is true.” Here’s what Mike said regarding my illustration:

MDR would say that both classical realism and solipsism (specifically, ontological solipsism) make fundamentally untenable assumptions. We do not have unfettered access to an ultimate absolute reality, and we have ample reason to assume, based on evidence arrived at through induction, that a reality external to our minds does in fact exist. MDR does not summarily declare either position false, as Steven asserts; rather, neither can be said to be true or false.

Mike has misunderstood me. I never said that on MDR both theories must be false, rather I said neither is true. And this is exactly what Mike is saying here. So Mike and I are in agreement here, he just didn’t know it. So to return to my intended point, on MDR neither realism nor solipsism is true, or false. In fact, such talk is, on MDR, superfluous. But this, again, is where the absurdity lies. For either a reality exists apart from subjective observers, or it doesn’t. This pure logic: either A or not-A. What we cannot say is “neither.”

To press this point further, let’s imagine two exclusive theories (different than the ones utilized above): Either you (the reader) exist, or you do not. It seems purely common sense to say that only one of these can be true and one at least must be true—the law of non-contradiction necessitates this. But on MDR we cannot say this, rather we must say neither is true or false—talk of truth is meaningless here. Yeah…good luck with that. If this is not enough to demonstrate the nonsense and absurdity of MDR then I do not know what is.

But the point can be pressed even further than this. For the main point of Mike’s post is an attempt to demonstrate that I have misunderstood MDR, and that my attacks against it are invalid. But wait. How, on MDR can Mike say that any “model” one espouses, whether mine or anyone else’s, is incorrect? He can’t. Remember Hawking: “it is pointless to ask whether a model is real[.]” Talk of real, unreal, true, or false, is meaningless here. So, why then is Mike so determined to show that my own model is wrong? Is he perhaps convinced that his model is correct, and that therefore it accurately describes an actual state of affairs? Of course he is. And thus, although he claims to adhere to MDR, his actions betray his beliefs.

Mike then wraps up his post by stating the “most important point” of MDR:

MDR renders meaningless the distinction between "reality accessible to us" and "reality in itself". Of course most philosophers and scientists (including Hawking) operate on the provisional, inductively-derived assumption that an absolute reality does exist. But we do not have an unfettered, privileged access to such a reality in which one level of explanation (or one 'frame of reference') successfully describes all phenomena.

Mike, again, seems to miss the blatant contradictory nature of MDR here. He, and Hawking, claim that we do not have a model-independent concept of reality, and that we can only find utility in models, not truth or reality in them. But this itself is a claim about the nature of reality. Just ask the question “Is it really the case that we have no model-independent picture of reality?” The answer will commit one to make an objective claim about reality. You see, MDR attempts to bypass the metaphysical debate about the nature of reality—it’s trying to say that the whole debate itself is superfluous and meaningless. But by doing this MDR is throwing itself into the debate, whether one likes it or not!

Hitherto I don’t believe Mike has accomplished what he set out to do. First, He didn’t really show that I misunderstood MDR. In fact he seems to have misunderstood me, and at times our understanding was exactly the same, even though he failed to recognize such. Second, Mike has failed to salvage, in my opinion, any remains of a coherent and respectable theory in MDR. It remains an incoherent, absurd, and self-refuting philosophic position. As Hume would say, let us commit it to the flames.

Model-Dependent Realism: An untenable epistemology

All the metaphysical discussion as of late on this blog has left my mind racing on many things. Yet, one thing I felt in particular that needed to be tackled was the epistemological framework known as Model-Dependent Realism (henceforth MDR). This epistemology is a favorite of Mike D over at The-Aunicornist. Frankly, I get quite tired of having this idea thrown around when it is so blatantly ridiculous, and thus I felt the need to demonstrate such.

So, let us first expound this epistemology—only to be found promulgated in The Grand Design by Stephen Hawking, which should already make said epistemology suspect, since the book is, to be blunt, quite terrible. 

[O]ur brains interpret the input from our sensory organs by making a model of the world[…] If two such physical theories or models accurately predict the same events, one cannot be said to be more real than the other; rather we are free to use whichever model is most convenient.

 There is no picture-or theory-independent concept of reality. […] These mental concepts are the only reality we can know. […] [A] well-constructed model creates a reality of its own.

 It should be obvious upon first glance how extreme and ridiculous MDR is. It is an amalgam of previously known philosophical positions such as pragmatism, constructive empiricism, and some type of idealism—all, at least to me, untenable philosophies in themselves.

Nothing is “real”, except my theory

Probably one of the most extreme promulgations in MDR is that one’s “model” cannot be said to be more real than another’s. This is pure nonsense. First, let it be understood that MDR does not claim that if two theories can both accurately describe or predict the same observations, then we cannot, at the moment, determine which theory actually conforms to objective reality. No, MDR is claiming that neither theory conforms to reality more than the other—that is, neither theory is more real than the other.

To illustrate the depravity of such a position, let’s take two well-known models of reality: realism and solipsism. The realist states that an objective reality exists independent of observers, while the solipsist states that only his mind exists. Surely these models are mutually exclusive, and either one or the other has to be predicated of reality—that is, either only I exist, or a reality exists which I am a part of; there is no middle ground here. However, on MDR we cannot say that one is true while the other is false. Rather, neither is true. Yeah…this is the intelligence blooming from the mind of Hawking, and this is why Einstein said, “the man of science is a poor philosopher”.

That being said, MDR has much bigger problems than this. You see MDR, though denying the objective reality of theories, must uphold the reality of at least one theory to be valid. Remember the following foundational claim of MDR: There is no picture-or theory-independent concept of reality. Now, is this assertion true or false—that is, can it be predicated of reality, or not? If so, then MDR has just made an objective claim about the nature of reality, the very thing it claims cannot be done. If not, then MDR is false. Either way, MDR refutes itself.

Pragmatic, for whom?

Remember that MDR asserts that if two models of reality are equally on par at describing our observations, then we can use whichever model we find most valuable or convenient. This is pure pragmatism—and MDR, just like any philosophy founded on pragmatism, runs into problems because of this. First, if one can adopt any model based on its utility, then the validity of models is subject to the whims of individuals. For what’s pragmatic for me will not necessarily be pragmatic for you. But wait. I personally find it ridiculous, and therefore, not pragmatic, to hold to MDR; and my worldview, which excludes MDR, makes the same observations of reality as any other. So, since it is convenient for me to reject MDR, then, on MDR, I am free to do so and no one can claim that what I have done is invalid. Thus stated, MDR has led to the rejection of itself!

Second, MDR again pulls the rug out from underneath itself. Pragmatism is a theory of truth which explicitly rejects the correspondence theory of truth—i.e., a statement is true if it corresponds to reality. But, the only way to do this is to make an objective claim about reality—that is, truth as such is illusory. However, to make such an objective claim is to go against MDR—which rejects objective claims. MDR once again must do the very thing it claims cannot be done.

There are many more problems with MDR, but I do believe its untenability has hitherto been demonstrated. Advocates of MDR seem to make their case solely on the basis of how our sensory organs take in datum and relay it to our brain. This seems, to them, to demonstrate that only the appearance of reality is accessible to us, as opposed to reality in itself. But, notice that this is once again an objective claim regarding what really goes on when we abstract concepts from the observed. More importantly there are many epistemologies out there that take such cognitive facts into account while still proclaiming that reality in itself can be known. And who are model-dependent realists to say they’re wrong? They can’t, because their epistemology doesn’t allow them. On the contrary, it is much more convenient to affirm an epistemology that promulgates the reality of the observed, and therefore we see one more instance of MDR shooting itself in the foot. 

The death of metaphysics?

A topic that has been heavily discussed between Mike D, over at The Aunicornist, and I is the validity of utilizing metaphysics as an inquiry into reality. Mike believes that metaphysics is a useless endeavor which centers itself on superfluous concepts that are not necessary, and not even accurate, for describing reality. In my eyes Mike presents some of the best arguments against the use of metaphysics, though I do believe his arguments fall short in the end. Nevertheless, Mike has just posted a new article entitled The death of metaphysics, and I therefore felt obligated to continue this dialogue, which is centered on such a crucial topic, and point out the errors I believe Mike has made.

 I will begin where Mike seems to make some strange statements regarding his adherence to model-dependent realism:

[Model-dependent realism] essentially says that we do not have unfettered access to ‘absolute truth’ or complete knowledge of what is literally real. All we can do, then, is construct models with varying degrees of predictive reliability. Fussing over what is real is meaningless[.]

 First, let it be made clear that model-dependent realism is itself a metaphysical position. That is, by claiming that we don’t have unfettered access to absolute truth Mike is claiming something about the nature of reality. So, Mike is utilizing metaphysics…to debunk metaphysics.  Good luck with that.

 Second, I doubt any metaphysician has ever claimed that we can have complete knowledge of reality; we are not omniscient, indeed. But, this doesn’t mean that we cannot predicate things of reality with certainty—in fact, the laws of logic dictate that we must, on pain of contradiction. So surely we can know things of reality, and therefore we can say some things are literally real. It is literally real that reality exists (this is true even if Cartesian doubt is valid), that I exist, or that I am experiencing certain cognitive datum. Now, these might seem trivial propositions at best, but that’s not the point. They are only trivial because they are axiomatic and self-justifying. Yet, it is these very types of propositions that we can be absolutely certain conform to reality, and therefore the claim that we cannot know things absolutely true about reality is false.

Mike continues on his vindication of model-dependent realism:

Often, what we think is real turns out to be something else. Predictions often do not hold true; we’re subject to false memories and cognitive biases; and our own cognitive models of reality often fail us. This demonstrates that we do not have access to Absolute Truth, or complete knowledge of what is literally real.

 Mike’s argument here seems to lead to a completely different conclusion. If we’re subject to invalid models of reality, then the only way we could know this is if we can tell valid models of reality from invalid ones. For example, the only way we can tell when something is an optical illusion is if we know what that thing actually looks like. Similarly, to differentiate true models from false models can only happen if we can indeed arrive truth. Mike’s attempt to run away from (what he calls) “Absolute Truth” only pulls the rug out from underneath him.

 Moreover, remember that Mike here is still predicating this epistemological framework of reality. That is, he is saying that it is true that model-dependent realism is a correct epistemological description of reality. Notice the problem?

 Mike then articulates what he believes to be a key problem with metaphysical inquiry:

The problem with this type of thought is that the very semantic framework that is used to construct metaphysical propositions and derive their conclusions are fully dependent on both our physical embodiment and our empirical experience.

This statement puzzles me, because a majority of metaphysical inquiry deals with contingent a posteriori inquiry; that is, ontological truths which can only be predicated of our observed universe. Open any metaphysics textbook and you’ll see that the breadth of topics covered are topics that are only relevant to our observable reality. So, why is Mike getting all worked up by the fact that metaphysics abstracts concepts from the observed and uses them to describe the very same observable reality? The answer is that Mike only gets worked up when these metaphysical inquiries are labeled as “necessary” and are projected beyond the limits of our experience:

[I]t is meaningless to use words that describe spatiotemporal relationships without the context of spatiotemporality[…] This demonstrates that these sorts of metaphysical propositions are nonsensical.

First, it is not nonsensical. In fact, physicists do this all the time. Physicists, in order to best make sense of certain states of the universe, invoke such spatiotemporal language even where such language is out of context. They constantly talk about what it would be like inside a black hole, or what characterizes a singularity, or the weirdness of the quantum world, even though the language employed doesn’t exactly get it right. But, does anyone claim that what these physicists are saying is therefore nonsensical and meaningless?

 Second, and more importantly, most concepts utilized by metaphysicians that are seen as necessary--and therefore must apply anywhere and everywhere--are concepts that do not only have their context in spatiotemporality. Take the crucial concept of identity. Was this concept abstracted from experience? You betcha. But, can it only be predicated of things measurable in space-time? Not at all. Identity is, and must be, predicated of propositions, concepts, meanings, and mathematical concepts, all of which are not spatiotemporal.

 Moreover, what’s important is not just that concepts like identity can be applied anywhere—whether to things in space-time or not—but that they must be applied everywhere on pain of contradiction. That is to say, if one were to attempt to deny (anywhere) a necessary existent like identity, they would defeat themselves logically. A perfect example of this is the first law of logic. Try to deny such a law and you’ll find yourself entangled in self-refutation. And this means that such a proposition cannot fail to be predicated anywhere--for the same thing would happen. Thus stated, we see that metaphysics can, and must, reach beyond the bounds of our experience.

 Mike continues:

We can thus avoid the confusion of these metaphysical propositions simply by pointing out that there is no reason to think that the words used to construct such propositions are meaningful outside of the empirical context from which their meaning is abstracted in the first place.

On the contrary, we have seen that metaphysical concepts and propositions need not be projected “outside” the universe in order for them to be projected of things (e.g. mathematical concepts and propositions) outside of the empirical. And with that in hand we have warrant for applying such metaphysics outside the bounds of our immediate experience.

 We inferred a number of things here: 1) One’s own attempt to bury metaphysics necessitated the use of metaphysics, thereby rendering such a position self-defeating; 2) Mike seems to not understand that the type of metaphysics that he disdains so much does not even constitute the majority of metaphysical focal points, which means that his campaign against metaphysics is misdirected; and 3) metaphysics can and must, contrary to Mike, be projected to realms beyond our observable experience.

 So, the death of metaphysics? I think not. In the words of the late E.J. Lowe: [Metaphysics] is one in which no rational being can avoid engaging in at least some of the time. We are all metaphysicians whether we like it or not.
