Mike D, over at the newly rejuvenated The A-unicornist
has decided to engage my review--my original posts can be found here: Part I, II, and III--of the philosophy of embodied realism, as
promulgated in Philosophy of the Flesh, that I wrote about six months ago—I
guess better late than never. His three posts can be read here, here, and here.
While I did plan on writing more reviews on embodied realism, I instead found
that the common readers of my blog were not really interested in the material,
and, moreover, after my last post—wherein I attempted to demonstrate that
embodied realism was self-refuting—I felt that I had adequately cracked the
foundation that embodied realism lays upon, and therefore not much more needed
to be said. But Mike D doesn’t agree (shocker!), hence his review, and thus I
feel the need to revisit this topic in order to dispel the fallacies in his
thinking and arguments. Sit back and enjoy, preferably with a cup of coffee.
Correspondence Theory of Truth
My first post on embodied realism was an attempted
defense of the correspondence theory of truth, in opposition to embodied
realism which claimed that such a philosophy is false because it ignores our
levels of embodiment and the corollaries therein. Those that read the post will
remember that I carefully made my point that all that is required for the
correspondence theory to be valid is for truth-bearers to correspond to
truth-makers. This is important, because Mike makes a mistake right off the bat
in his review by claiming, contrary to the very post he’s answering, that the
theory claims that the concepts in our minds correspond directly to real things
in the world.” Well, no, this is not what it says, or at least this is not how
I articulated my position for reasons that I specifically outlined in the first
post, based on the distinction between formal and virtual properties that adhere.
So Mike is already misstating my position.
Now, this idea of correspondence is a crucial reason
why the example of the reality of color is an example utilized by both Mike and
I. As was highlighted before, color does not exist without human embodiment—that
is without the subjectivity of the cognitive and visual human apparatus. But
this does not mean that the reality of color is not objective, that is, it
doesn’t mean that it can be said to objectively obtain in reality. As I said
before, there is a difference between objective truth, and truth obtaining
objectively. Color cannot obtain without an embodied observer, so it does not
obtain objectively, but this does not mean that color does not exist in
objective reality. To argue such is to engage in conflation. Now, Mike did
engage this point of mine, and found my definition of “objective” wanting:
So what on Earth could Steven mean when he says that
he agrees with the authors that color does not inhere in the world objectively,
but then he says that it is objective "virtually"? Steven appears to
be operating on an idiosyncratic and, frankly, ambiguous definition of
"objective". Objectivity generally means that the truth of a
proposition is not dependent on any subject.
Here’s what I mean, and it reflects back to what I
said above. All that is required for a statement to be objectively true is for
a truth-bearer to correspond to a truth-maker. That’s it. It is the
correspondence that must be objective, and not the bearer or the maker. So, why
is this a problem for Mike? Well, the embodiment of man only renders the
truth-maker to be subjective, and not the correspondence itself. For instance,
if I say “The grass is green”, you have three parts related to the truth
of this statement. You have the truth-bearer in the statement itself, you have
the truth-maker realized in the color obtaining subjectively, and you have the
correspondence between the two. Notice that the correspondence is objective,
even though the truth-maker is subjective. Thus, the truth “The grass is green”
is still objectively true, even though we need to be embodied in order for
color to obtain. Embodiment, then, simply does nothing to call the objectivity
of truth into question here, and therefore Mike’s position here is false.
Mike then continues his point, predicated on the same
misunderstandings he expounded above:
It's quite clear that color, as well as conceptual
spaces like skies and gardens, cannot fit any common-usage definition of
objectivity. Steven seems to think (as would be the case in the correspondence
theory of truth) that embodiment serves to "obtain" objective truths.
But this overlooks the fact that our minds actually create and impose
conceptual structures onto the world. Colors, skies, and gardens are all examples
of things that do not exist in the classical sense of objectivity, but rather
are what Lakoff describes as "mutliplace interactional properties":
phenomena that only exist as an emergent function of our neurocircuitry
interacting with the world around us.
Again Mike is conflating objective truth with truth
obtaining objectively. Color obtains subjectively, but it is an objective truth
that it exists. To reiterate, the fact that our embodiment can create and
impose conceptual structures onto the world only affects the truth-maker, and
not the correspondence itself, and therefore this subjectivity does not affect
the objectivity of the correspondence itself.
Mike seems to have not caught it when I made this point in my original
post. Moreover, this all stems from his poor understanding of what the
correspondence theory actually means and how I originally articulated it—as we
saw above.
Mike then incorrectly sums up my position and draws
(also incorrect) conclusions from it:
Looking back, Steven's argument is just all over the
place. He defines a property inhering "virtually" in such a way that
is all but indistinguishable from Lakoff's position, and even concedes that
Scholastics like him do not think color exists objectively in the world, just
as Lakoff argues. Except then he says it does, if by "objective" we
mean "virtually objective", even though virtual inherence (as he's
defined it) directly conflicts with classical objectivity. As it stands,
Steven's objections so far are just a mess.
First off, Mike incorrectly articulates my position by
claiming that I conceded that color does not exist objectively. I never said
that. I said that color does not obtain objectively, and this again
demonstrates that Mike has misunderstood my position. I believe that the statement
“color exists” is objectively true, and my only qualification is that the
nature of its obtainment is subjective. There is a difference between the two,
and unfortunately it has evaded Mike’s comprehension.
Second, Mike claims that virtual inherence conflicts
with classical objectivity. This is false once again. To reiterate again,
classical objectivity only requires a correspondence between a truth-bearer and
a truth-maker. And a property that inheres or obtains virtually does not call
this requirement into question. It only entails, as I said above, that the
truth-maker obtains subjectively, but this does not make the correspondence
itself subjective. So, contrary to Mike, no assaults have been committed
against classical objectivity, and correspondence theory remains intact.
However, we’re not finished here, and we can see that
things are even worse for those who would attempt to dispel the correspondence
theory. For think about what one is saying when they say the correspondence
theory of truth is false—as Mike and Lakoff do. They are saying that the theory
fails to adequately represent the way reality operates—and this relies on the
very same theory of correspondence. Even the authors of Philosophy of the Flesh
do this! In order to make the case against correspondence theory they tried to
show that the levels of embodiment demonstrate that the correspondence of
correspondence theory is not a neat one-to-one relation as is supposed, and
therefore the theory is false. But by doing so the authors are utilizing the
very theory they’re attempting to disprove! That is, they’re arguing that
correspondence theory cannot be true, because it fails to accurately correspond
to the way reality actually operates. Thus, not only has Mike’s case not been
made, it’s not even possible to make it.
Levels of Embodiment
Mike then (still in his first post) transitions to a
particular criticism I made, regarding the levels of embodiment. Let me
re-expound my argument presently, because it will be momentarily seen that Mike
completely misunderstands it.
Remember that the authors of Philosophy of the Flesh
claimed that there are three distinct levels of our embodiment: the neural,
phenomenological, and cognitive unconscious level. The authors then claimed
that there can be no truth statements that are “level-independent,” that truths
can only be stated at distinct levels and distinct vantage points and that one level cannot be erected
over and against another. (This position always reminds me of Obi Wan Kenobi in return of the Jedi stating "What I told you was true, from a certain point of view." Who knew Kenobi was an embodied realist?) Going back to our discussion on color, the authors
stated the following:
Both the phenomenology-first and science-first
strategies are inadequate in one way or other. If we take the
phenomenology-first strategy, we miss what we know scientifically is true about
color. We get the scientific metaphysics of color wrong. Our “truth conditions”
do not reflect what we know to be true. If we take the science-first strategy,
we do violence to the normal meaning of the word and to what ordinary people
mean by “truth.”
The authors are saying here that, with regard to
color, we cannot simply erect the neural level of embodiment as the
end-all-be-all of the color discussion by saying that, scientifically, color
does not exist—because then we do damage to the phenomenological level wherein
color indeed seems to exist. But neither can we erect the phenomenological
level over above the other levels because then we do damage to what science
actually tells us about the physics of color.
Here’s where my point came in. My point was that
sometimes we have to erect one level above another, and that many times doing
damage to one level of embodiment is allowed and is necessary—at least, if we
want our predications to be coherent. A prime example that I highlighted in my
post, is cases where we know, through science, that our immediate qualia—a part
of our phenomenological level--is wrong, or deceiving. And here we should be
able to truly say that our phenomenological level is wrong and inaccurate, and
the only way we know this is through science. And therefore in these cases a
“science-first” strategy is logical and necessary.
Now, here’s what Mike had to say regarding this point,
and it’s not even in the ballpark of answering or contending with my point:
The authors are not asserting that the correspondence
theory of truth assumes the phenomenological level to be true all the time —
indeed as Steven notes, the authors point out that the correspondence theory
fails to even acknowledge these different (and sometimes conflicting) levels of
truth, and that is the central issue.
Mike is quite confused here. First, I’m attacking the
position of embodied realism, as stated by the authors. So my point had nothing
to do with claiming that the authors were “asserting that the correspondence
theory of truth assumes the phenomenological level to be true all the time.”
Again, my point was not predicated on the authors taking this position.
Furthermore, correspondence theory was momentarily irrelevant to my point, so Mike’s
mention of it is misplaced and confused.
The point that Mike missed was that, contrary to the
author’s point above, our levels of embodiment can in fact be erected over one
another and do damage to each other. The example I utilized to make my point was
that of hallucinations. Why? Because on the phenomenological level, a
hallucination is in fact experienced. It does constitute valid qualia. And
therefore, on embodied realism, a hallucination is seen as “true” on that
level. But scientifically and neurologically, we know that the object of the
hallucination does not actually exist in objective reality. So, should we just
sit on our hands and claim that a hallucination is “real” from the
phenomenological level, but false from the neural level, because God forbid we
let one of these levels make the decision for us? Of course not. A
hallucination is simply a false perception, and that’s it. Science wins here.
And therefore there is one level, in this instance, that is erected above the
“truth” of another and subsequently renders it false.
But, Mike’s not having it:
The authors do not at any point either state or imply
the ridiculous assertion that all phenomenological claims must be taken at face
value (Steven said, "just because we perceive something does not mean it
is there”, with which the authors would of course concur). And importantly, the
authors do not assert that different levels of embodiment are equally true at
all times.
Whoa there. First, I never claimed that the authors
stated such. Mike has once again misunderstood my point. My point was not
predicated on the proposition that all phenomenological claims must be taken at
face value, or that the levels of embodiment are equally true at all times.
Remember that the authors claimed that embodied realism requires us to jettison
the belief that we can formulate a unique and complete description, on one
level of embodiment, of a particular state of affairs. Therefore, my point, to
reiterate it ad nauseum, is that in the case of hallucinations we can, and
must, formulate a unique and complete description of the event based primarily
on neuroscience and psychology, which necessarily does damage to the “truth” of
the phenomenological level, and this contradicts the author’s claim that this
should not be done.
But wait, Mike’s not done:
When one level of embodiment produces stable truths
that contradict unstable truths of another, the level of embodiment producing
stable truths is privileged. That is why we're skeptical of hallucinations of
dead relatives: we know from neuroscience that people in certain conditions
experience a wide variety of hallucinations that may or may not include
deceased relatives. The results from neuroscience are replicable, stable
truths; visitations from dead relatives are not. When multiple levels of
embodiment produce stable truths — as in our study of the mind through
neurobiology, neurocomputation, and cognition — they create an overlapping and
complimentary understanding — the kind that allows to us to learn that the
correspondence theory of truth is, in fact, wrong.
Big problems here. Mike is doing exactly what the
authors say cannot be done, and is actually agreeing with me in the process.
That is, Mike here is arguing for a science-first strategy and is arguing for
the momentarily privileged status of the “truth” of the neural level, and is
thereby doing damage to the “truth” of the phenomenological level. The results
from neuroscience, while they might indeed be stable truths, are being erected
as the end-all-be-all of the discussion, and are seen as giving us a complete
description of the state of affairs of hallucination.
But Mike is even more confused than his oblivious
agreement with my stance would indicate.
He claims that his argument works because in this instance you have
“multiple levels” that produce stable truths, as opposed to just one level
being erected over another. But this is blatantly false according to the levels
promulgated by the authors of Philosophy of the Flesh that Mike reveres. The
examples of disciplines that converge on these stable truths that Mike
lists—e.g., neurocomputation, neurobiology etc.—are all subsumed under one
level of embodiment, namely that of the neural level—again, according to
Lakoff. So contrary to Mike, if these stable truths—which are subsumed under
the neural level--can indeed call the phenomenological view into question, then
you have the epitome of one level gaining a privileged status above the
others—the very thing Lakoff said couldn’t and shouldn’t be done. So either Mike
is right and his beloved Lakoff is wrong, or Lakoff is right and Mike
obliviously agrees with me. Either way it’s a lose-lose for Mike.
So did Mike really demonstrate that my criticism of
the levels of embodiment was wanting? Hardly. He only demonstrated that he has
trouble comprehending both my position and Lakoff’s.
Embodied Truth
My second post dealt with the theory of truth put
forward by Lakoff in the form of embodied truth. I began the post highlighting
a remark the authors made on how we conceptualize truth, and Mike had a
visceral reaction to it:
Steven is already so far off the mark here that I'm
just gobsmacked. The authors are not claiming there are no objective truths, or
that truths do not exist independently of us. They are certainly not arguing
that something is, for example, "true for me" in the form of pure
subjectivism. Rather, they're talking about how human beings conceptualize
truth, and how shared truths become stable truths.
Is Mike right here? Actually I believe he is
(partially), and I do believe that I misread or misunderstood what the authors
were getting at. I conflated the psychology of how we conceptualize truth with
embodied truth as a philosophical theory of truth. So Mike is correct in
highlighting this mistake of mine. Fair enough.
However, if the whole notion of embodied truth is not
a theory of truth per se, then how, on embodied realism do we actually ground
truth? Well, remember that due to the different levels of embodiment, we can
have distinct truths at different levels, but we can have no neutral viewpoint
apart from these levels from which to make objective predications? But then,
how do we arrive at truth? That is, how can we say X is the case, or is not the
case?
Here’s where Mike and embodied realism misstep. I
claimed in my original post that a theory of truth is not amendable to
scientific results like that of embodied cognition. Why not, you ask? Because
one first needs a theory of truth before one can engage in science. Science
presupposes truth, not the other way around. Here’s how Mike responded when
this was brought up:
But of course, the authors discuss at length the
assumptions underpinning scientific realism to which they adhere. The results
of embodied cognition do not, as Steven asserts, constitute an a priori theory
of truth, but rather illuminate how human minds conceptualize, understand, and
share truths. The authors state, "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."
Let the reader understand that Mike completely
side-stepped the issue. I don’t recall any instance where I asserted that
embodied cognition constitutes an a priori theory of truth—I don’t recall it
because it never happened. However, this isn’t even the issue. The issue is
that embodied cognition simply does not have the power to make any such comment
on what truth is, or is not, since it presupposes truth in the first place. If
B relies on A, then no corollary of B can call A into question. And this is the
issue to which Mike is completely silent on.
Embodied realism has not, then, called correspondence
theory into question (as we saw above) and it has given us no other theory to
put in its place. How then can embodied realism call competing philosophical
theories false?
Metaphysical realism
My last post on embodied realism dealt with its
relinquishing of metaphysical realism, and why I believe this to be not only
false, but self-refuting. For example, the authors claim that “[Embodied
realism] denies that we can have objective and absolute knowledge of the
world-in-itself… [and] denies on empirical grounds, that there exists one and
only one correct description of the world[.] (p. 96) My claim was that this position
can only be taken seriously if it is being objectively predicated of
reality-in-itself. That is to say, this position is effectively saying that
reality is such that X is the case—that is, that we cannot know
reality-in-itself. But, this obviously entails that we know something about how
reality objectively operates, otherwise the position is literally false.
But Mike is prepared to answer this claim:
When the authors say that there is no "purely
objective" understanding of reality, they mean "objective" in
the unembodied sense of classical scientific realism: the idea that our mind
directly grasps objective truths, and that things like concepts, abstractions,
metaphors, and logic are part of the rational structure of reality. The
authors' thesis is that those phenomena are emergent properties of the embodied
mind, so that while indeed we can safely and reasonably assume that we can
attain knowledge of an objective external reality, we cannot do so in a manner
that is itself untethered from the cognitive framework through which we
necessarily view the world.
The problem here is that Mike’s qualifications of the
author’s position do not actually rescue said position from incoherency. First,
I was already aware of the author’s belief in attaining knowledge through
“stable truths”. By “stable truths” the authors simply mean repeatable and
reliable patterns. The problem is that this claim still undermines their
position. Consider this question: Is the statement “stable truths can attain
knowledge” itself a stable truth? I don’t see how, since this is not a
proposition that is susceptible to the type of scientific investigation that
yields repeatable and reliable patterns. And this is because one must first
have a priori knowledge before one even engages in science, and therefore
before one begins the search for stable truths. Therefore, knowledge is already
presupposed by the search for stable truths and thus the latter cannot be
defined in terms of the former. (We’ll get more into this below when we speak of
metaphysical assumptions.)
But it’s even worse than this for the embodied
realist. For how do Mike and the authors know stable truths can and do in fact
attain the status of knowledge of reality? They already need beliefs about the
nature of reality in order to predicate this statement. Since we are part of
reality, we need to already believe things about the nature of reality in order
to state our epistemic relationship to it.
And Mike can’t turn back to stable truths to ground this belief, since
he would be arguing in a circle. Mike is stuck between a rock and a hard place.
Thus we see
that no matter how the embodied realist wants to jettison metaphysical realism,
he will always return to it.
Metaphysical assumptions
Next Mike asks what I think is a very important and
pertinent question:
The real conundrum is this: can cognitive science
really say anything about how we fundamentally conceptualize reality, since
science itself requires us to make philosophical assumptions?
He continues down the line:
It seems reasonable to conclude from his objections
that Steven believes empirically-informed philosophical insights to be
self-defeating — since those empirical results themselves rely on some set of
philosophical assumptions in the first place. But as the authors have argued,
only a minimal set of methodological assumptions is necessary for scientific
inquiry to proceed. From those basic assumptions, we can gain insight into how
our minds construct and interpret data, and we only need to make a very minimal
few assumptions along the way.
A couple of things here. First, I in no way believe
that empirically-informed philosophical insights are self-defeating. I only
call empirically-informed insights self-defeating when they result in a
reductio ad absurdum. That is to say, I find philosophical positions based on
science to be self-refuting when they attempt to call into question the first
principles that are necessary for knowledge and the intelligibility of the
world, which is what science is predicated on in the first place.
And what exactly are these first principles, or
assumptions, that are necessary for scientific inquiry? Well Mike, following
Lakoff, lists the following:
• Objective
reality exists, and we can have stable knowledge of it
• Other
minds like our own exist
• These
minds can be studied empirically
• The
empirical results of those studies can be generalized to all human minds
While I (for the most part, and tentatively) agree
with the assumptions listed here, they are by no means exhaustive. Before we do
science there are still many more principles that need to be proposed. We need
to assume that there exists causal regularity and uniformity in nature. We need
to assume the validity of induction. We need to assume that things are
intelligible in themselves. We need to assume the laws of logic. We need to
assume a theory of truth. We need to assume, not that we can have stable
knowledge of reality, but that we can predicate things of reality that
accurately correspond to the way reality actually is.
Now why is the listing of all these assumptions
important? Well, because if science presupposes these propositions, then no
corollary of science can ever call these into question. You simply cannot pull
the rug out from underneath yourself, and this is what Mike fails to
comprehend, as is evident by these statements of his:
If we accept these assumptions — as most all of us do
— then the philosophical implications of convergent empirical evidence across
multiple scientific disciples cannot be ignored. When convergent scientific
evidence informs us that most of our reasoning is unconscious and metaphorical,
or that cognitive metaphors are crucially tied to our embodiment, we have to
acknowledge that these results undermine classical conceptualizations of
metaphor, reasoning, and indeed truth itself.
This is simply false. The philosophical implications
of “convergent” empirical evidence can indeed be, and must be, ignored when
they call into question the principles that science itself rests on. As I
reiterated above, if B presupposes A then no corollary of B can ever call A
into question. This is a logical necessity. And this is why Mike’s position,
that of embodied realism, continually refutes itself, because it keeps trying
to bite the hand that feeds it. You simply cannot kick out the foundation your
position is resting upon and expect it to remain intact and coherent.
--------------------------------------------------------------------------------------------------------------------------
If you’ve made it this far I congratulate you. (To be
honest, I barely made it this far.) We’ve witnessed a lot of things in this
post. First, we’ve seen that Mike was quick to point out my supposed poor
understanding of embodied realism, when in fact a lot of the time he could
barely rearticulate my own criticisms, or his answers sidestepped them so far
that they became irrelevant and peripheral to the discussion at hand. Second,
we saw that Mike could not slay the correspondence theory of truth as he wanted
to; neither could embodied realism replace it with any coherent theory of its
own; neither could embodied realism’s levels of embodiment put the
correspondence theory into question at all. Third, we saw that Mike’s attempt
to save embodied realism’s “realism” through the use of “stable truths” did not
work, and could not work even in principle. Lastly, we saw that the results of
embodied cognition do not have the power to call our most basic metaphysical
principles into question, and that when embodied realism attempts to utilize
these results to call said principles into question, it ends in
self-refutation.
So that’s it. I have nothing more to say. Embodied
realism is false and self-refuting, and despite Mike’s efforts, it cannot be
rescued from the depths of incoherency.
