There is no shallow end to the philosophical pool.

-- P.F. Strawson

The correct view, I shall argue, is both the one left standing when we have seen how other views fail, and the one that answers best to these human concerns.

-- Derek Parfit, Vol II On What Matters

In this note I will briefly grapple with the question of what philosophy is and is not. As a part of answering this question, I will also engage with the question of why philosophical problems are so perennially perplexing. I include this because their perplexing aspect sheds light on what they are at heart. Both topics cover such a broad landscape that I can only hope to do a brief fly-over here.

2.​

Standard examples of philosophical questions are "What is truth?", "What is justice?", "Is there right and wrong in the world?", "Is everything a physical thing?" I will start by claiming that looking for some strictly defined common denominator to all of these questions is a mistake. There is unlikely to be any one ingredient the inclusion of which makes a question distinctly philosophical. It might be objected that they are not immediately answerable to experience and that this is the ingredient. While this is certainly in the mix, it won't do for distinguishing the philosophical from the non-philosophical unless we want to call all kinds of questions philosophical like "What would my life have been like if I grew up in France?", "When is the best time to have children?", or "Was this actually the best move, or did I just get lucky?". While we can think of superficially experience-related answers to these questions, the chain of reasons we would justify our answers with terminates in reasons that involve values or abstract commitments. Conversely, some branches of philosophy are almost entirely comprised of confrontations with immediate experience, phenomenology, for example.

There are two claims we could make about a supposed essence of philosophical discourse.

• That some discourse includes $X$ , automatically makes it philosophical. (has $X$ $\rightarrow$ is philosophical)
• Having $X$, is a necessary condition for some discourse to be philosophical. (is philosophical $\rightarrow$ has $X$ )

The first seems fruitless, beyond the boundaries drawn by historical contingencies or university departments. The second it seems, can only be given a fuzzy definition:

• is philosophical $\rightarrow$ probably has $X$

There are some ingredients that seem to give us evidence that some discourse is philosophical, but it seems mostly connotational. "That question is one that philosophers tend to ask." is about all we can say on the matter with a high degree of confidence.

4.​

This brings me to the claim I will defend in this note about the "essence" of philosophical discourse. I claim that there is no type of discursive move one can make that is distinctly philosophical and no type of discursive move one can make that is distinctly not philosophical. That is to say, philosophical discourse is a member of a fuzzy set, or has a family resemblance with, all other types of cognitive (truth-apt) human discourse. Science, common sense, mathematics, philosophy, explaining the rules of a game, describing how to be a better actor, choosing which lure might catch more fish this afternoon, etc are all different human discursive acts that draw pluralistically from various toolkits in order to get some job done.

5.​

I am not denying that each practice listed above has probabilistically distinctive ingredients. I am denying that we have necessary and sufficient conditions for when one or the other is being done. The overwhelming majority of science involves empirical testing, but so does trying out a new recipe in the kitchen or the philosophical thought that it seems like we have free will. Science implicitly makes philosophical commitments and engages in conceptual engineering. Philosophy, when it does consult experience, frequently draws on the most basic and immediate experience, not "experiments" as we might think of them in science.

6.​

Where do we get the idea that it seems like we have free will? From merely understanding a concept?

7.​

If all discourse is "philosophical" (in some weak sense), because philosophical discourse shares more ingredients with other types of discourse than it has distinctly, then is all discourse "mathematical" and "scientific" as well? I think the names of these different realms of discourse do not denote something distinct that we are doing when we do them as much as they signify that types of discourse or thought belong to certain contexts. I am claiming that these different realms share much more in common than they do not.

8.​

That physical systems are causally closed, that all facts are physical facts, that every event has an explanation, that parsimonious explanations are to be preferred over less parsimonious ones, that only empirically verifiable results are to be expected from respectable science, and that the true demarcation of science from non-science is falsifiability. All of these claims, should we accept any of them, are not themselves empirical claims.

9.​

From a history of philosophy perspective, it is interesting that all attempts to do away with philosophy by some sweeping (usually philosophical) thesis end up with intractable problems of self-reference. The verificationist criteria is not itself verifiable. The entire Tractatus "cannot be said". Naturalists who reject metaphysics in place of physics must rely on non-naturalist principles to do so. And, more recently, radical pragmatist/post-modernist efforts to show that all claim to truth is merely a product of culture must rely on statements that seem to transcend culture to make that move (if it is to avoid being self-defeating).

10.​

If methods define the discipline, then we aren't going to get much clarity. Philosophy uses "scientific methods", and science uses "philosophical methods." Of course, I am not saying that there should be papers in Nature about "Synthetic A Priori" truths or papers in Mind about microbiological experiments. We have good connotational definitions, and I don't think we need better ones than the ones we have and employ.

11.​

Maybe we want to say that the philosopher when she makes deflationary a claim about a particular philosophical problem because it has gone unsolved for hundreds of years, is temporarily doing history? Is the philosopher qua historian actually doing empirical science because they are using the 'inductive method'? After all, such arguments are called 'pessimistic inductions'. Maybe the economist who implicitly excludes the possibility of strongly emergent non-physical events being the cause of some market trend is doing a bit of philosophy?

12.​

I see philosophy as just mapping out the inferential relationships between concepts we commit ourselves to by virtue of understanding/mastering those concepts. Or, making new/revised concepts and exploring the relationships those new concepts bear to ones already in use. Why should that be simple? Why should even the blueprint for how to do that be simple?

13.​

In any claim that we make, we are broadcasting to others what commitments we are making and what inferences can/should be drawn from what we say. This is, of course, a non-distinctive attribute of philosophical discourse.

14.​

When philosophy (or any other discipline in pursuit of truth) engineers concepts, I think the goal should be understanding. Understanding of what is the case, what would be the case if $P...$, what is necessarily the case, what is possibly the case, what is probably the case, and so on for all of the modalities (or perhaps, as many philosophers have thought, only some of the modalities, the others being reducible to those).

15.​

I think Strawson is correct in the opening quote to this note. So one might wonder: if Strawson is right and the philosophical pool has no shallow end, and there is nothing distinctive about the methods with which philosophy explores the implication-space of concepts we currently have (or create/modify), then why do these questions have no "shallow end"?

16.​

It is uncontroversial to say, and a testable empirical claim, that philosophical problems have evaded solution and dissolution by humans for thousands of years. Why? To continue roping some current reading material in here, I will bring in several of Eric Schwitzgebel's potential answers to that question from The Weirdness of the World (he frames the issue specifically in the context of metaphysics):

Possibilities as to why metaphysical problems seem to resist easier answers:

$1$. "Without some bizarreness, a metaphysics just wouldn't sell."

$2$. "Metaphysics is difficult." (There is a metaphysics out there with no Bizarre implications)

$3$. "Common sense is incoherent in matters of metaphysics."

$4$. (Adding one which Schwitzgebel brushes aside) "Metaphysical problems are pseudo-problems that are not truth-apt."

I was once convinced by $4$, but after feeling tensions in those ideas to be unresolvable, I now believe that some combination of $2$ and $3$ is the case. More precisely, I believe $2$ is true and $3$ is true, $3$ compounding the difficulty in $2$.

12.​

If this account is correct so far, then the discipline concerned with the connotationally philosophical problems is just one instance of the bringing-under-the-microscope of various conceptual claims and commitments that we make (implicitly or explicitly in our words and practices). Since those practices are complex and multifarious, it isn't unreasonable to expect the resulting web of commitments and entailments we get from exploring or engineering concepts in that web to be equally complex.

13.​

Why are philosophical problems hard? Philosophical claims (connotationally demarcated as the questions philosophers tend to ask) involve complex constellations of commitments between concepts that share a high amount of inferential connections with others but are weakly determined by our least rejectable workaday beliefs.

14.​

There is no shallow end of the pool because commitments about concepts (like knowledge or mind) have broad-reaching implications on nearly everything else we believe, but at the same time, particular commitments about those concepts are not strongly forced on us by experience or immediate necessity. Those broad-reaching implications are likely to collide with some other commitments in the common-sense picture of the world and these collisions form the many points of perennial philosophical debate. They are often collisions with our least rejectable beliefs, such as "I have free will". At the same time, since our experience can be made to fit many different philosophical views by shifting other commitments, we are rarely forced to choose one conclusion. Rather, we can spend a lot of time exploring all the various collisions with common-sense, or with other commitments we have, to find the most desirable set of concepts, commitments, and entailments. This, I believe, is simply a massive and combinatorially tremendous problem to solve.

15.​

Which theory of truth you endorse is unlikely to change your views about whether it is Wednesday or whether the moon landing was faked. It might change how you view the world quite significantly, though, over time. Total conceptual inefficacy does not follow from workaday inefficacy. There is some best theory to complement our understanding, but it will play out in a vast network of other commitments.

16.​

The route to understanding is like deciding the right path through something like the following decision tree:

• $G$ is something like the conceptual scheme, categories of experience, and resulting commitments that we have forced upon us by experience and our constitutions as human beings.
• Branches directly from $G$ are the various conceptual commitments we could reasonably take from that "starting point".
• Downstream (outward) nodes are the commitments entailed by those choices.
• Downstream (outward) branches are the subsequent conceptual decisions we can make as a result of those upstream commitments.
• Every decision path is reversible (we disavow certain commitments and undertake others)
• Taking one path is committing to a claim ("All things are physical things") or to a rule that defines a concept (e.g. to "be a pentagon is to be a plane figure with five straight sides and five angles" or to "having free will is to be an unmoved mover")
• We can turn back on commitments, rationally, for many reasons:
  • Recalcitrant experience
  • Conceptual inconsistency
  • Contradiction
  • Parsimony, to name only a few...

Ideal understanding would be achieved in this mock world when all commitments that $G$ is taken to entail are handled in such a way that makes the least collisions, internal contradictions, and inconsistencies. This may include any subset of the various possible branches that can carry us to some Peircian ideal. In the final understanding, we are left with the commitments that are, as Parfit says, the ones "left standing when we have seen how other views fail, and the ones that answer best to these human concerns" and which are, in the Peircian sense, subjunctively to be agreed upon by robust inquiry.

We must "test" each route to the periphery from $G$ by exploring the implications of each conceptual decision and seeing whether it collides with any upstream commitments or is rejectable for any of the above reasons. In the connotationally philosophical problems, few of the major choices are impacted by experience forcibly, and there is little cost to reversing our choices. We can expect this endeavor to understand to converge on truth only very slowly.

This may seem like a foundationalist picture, but it is not intended to be. $G$ is merely something less assailable (maybe by many magnitudes) than outer nodes and should probably be represented by a cluster of nodes. In reality, things are far more complex and the web of commitments is far larger and more labyrinthian. It is likely something more like a fractal version of this diagram where each node has in itself a vast depth of self-similar structure.

17.​

This picture has problems, clearly. I would not fully endorse it as an adequate picture of understanding. It is only meant to capture the nature of inquiry based on how claims entail other claims and how a structure of beliefs that is revisable, has much more up for revision the farther we get from $G$-like beliefs.

18.​

Those familiar with Quine's Web of Belief, might find the seeming inversion of the structure here confusing. Quine placed the more "revisable and "closer" to experience beliefs at the web's periphery. My little picture here is not a "web" but rather a node network of decision trees. I am representing something like the following. One could imagine each arm extending from $G$ as representing a realm of understanding. If it were the branch concerning metaethics, it might look like this:

And so one can imagine a branch for ethics, physics, aesthetics, philosophy of mind, cosmology, mathematics, and so on.

19.​

Under this view, expecting to solve major philosophical problems with ease would be as unlikely as solving any other combinatorial explosive problem to complete satisfaction. Consider just how combinatorially explosive things can become. Are there more moves in the real game of inquiry, than in the game of chess (which has a game-tree complexity of about $10^{120}$)? The problem is worse for several reasons:

• In chess, our making or not making certain moves does not entail much about any other moment of our lives or the lives of others. In the game of inquiry, our moves very much do.
• Individual moves/decisions in the game of inquiry are much less certain. How sure are we really that Non-Cognitivism is true? Might we not have to, over the course of many thinker's lives, work out lots of that decision tree's branches to be sure which account is the best "one left standing when we have seen how other views fail, and that answers best to human concerns"?
• In our incredibly simplified mock game of inquiry, there are no cross-discipline commitments. Nothing in the "epistemology" tree can collide or enforce anything in the "metaphysics", "metaethics", or "physics" tree. Surely this is not the case in human thought. Realistically, it probably looks like a much more chaotic version of this:

20.​

Consider what it is to "bite the bullet" in this mock game of inquiry. We take an upstream commitment that seems dubious to avoid the net more dubious downstream commitments of another branch.

21.​

The above is a faint sketch which could doubtless be filled in with much greater detail. For now I think it suffices to capture how I view philosophy, in a broad sense. I believe this sketch has strong merits. First, it allows us to explain why philosophical problems are truth apt without invoking empirically dubious differences between the different truth-apt human discursive practices and without appeals to weird mental faculties of platonic intuition. Second, it shows us why philosophical problems are expected to be very complex to solve. They are conceptually far-reaching, yet weakly determined by small portions of the decision tree in the game of inquiry. So, most of the time, experimentation cannot be expected to close the case.

22.​

These difficulties, however, do not make the solutions to philosophical problems any less truth-apt. To throw in the towel early is a sign of hubris. It is to mistake complexity for an illusion or a impassible barrier. Claims are best deemed not to be truth-apt, non-cognitive, when there is no conceivable grounds for their being considered true or false. This may apply to some philosophical problems. But conceivability is not possibility and, as I have argued, conceptual revision does take place. Even for the most intractable nonsense-seeming philosophical problems we have ever heard, we cannot responsibly say that no good sense could ever be given to the words. Obviously, though, there are better and worst problems to spend one's time on.

Philosophy begins in wonder. And at the end when philosophic thought has done its best the wonder remains.

-- Alfred North Whitehead

In philosophy, if you think the answer is obvious, you haven't understood the question.

I have decided to experiment with a new format here. It often takes me longer than I'd like to write/edit essay-style writing on this site. My goal in building and maintaining this little thing was always to solidify philosophical ideas of mine that were sort of just floating around in my thinking or scribbled in a notebook somewhere.

2.​

The new format is this. Numbered chunks of a few sentences or paragraphs. Just having numbered "thoughts" or "propositions" or whatever you want to call them is certainly a less organized mode of capturing thought, but I think it also wins over the essay in several important categories. I've borrowed this style from several philosophical heroes of mine and I think it served them well and maybe even enhanced my understanding of their ideas.

3.​

One change that has come over me philosophically in the last several years is an emphasis on not expressing/having complete certainty on most philosophical issues and being ok with that. I think that intellectual humility in the face of issues that have puzzled humans for thousands of years is the correct response. Empirically speaking, we should take seriously the notion that philosophical problems have been around for as long as humans have and have resisted simple conclusions. For me, this change amounts to a shift from "I think X" to "I assign a high credence to X".

4.​

In my personal experience, the less someone acknowledges tensions between their various philosophical commitments and the more convinced they are that have it all figured out, the less powerful their problem-solving seems to be. (I include parts of myself and previous iterations of myself in there.)

5.​

I used to fear thinking about philosophical problems and forbid myself from thinking about them because I knew certainty was unlikely to be found. The floor would fall out from under me. This has always discomforted me, and sometimes, I would be up until 2 in the morning, puzzling over something. Rather than fearing to play the game just because an all-out win was unlikely, I have come to enjoy the playing of the game.

6.​

I have recently been reading Eric Schwitzgebel's The Weirdness of the World. This book has significantly reinforced the themes of epistemic humility and withholding some certainty in philosophical thinking for me. In this book, Schwitzgebel claims that the proposed solutions to most major philosophical problems have Universal Bizzarness and Universal Dubiety. The former, by Schwitzgebel's definition, means that these proposed solutions have implications contrary to common sense and the latter means that these proposed solutions do not resoundingly compel belief. I think he is correct. Why that is the case is an interesting question for later, perhaps.

7.​

This new format accomplishes two things, one reflecting my changing philosophical attitude and one practical. First, it reflects some of the uncertainty involved in tackling philosophical problems in its denial of opening-body-conclusion type of thinking. Second, it makes creating these notes less time-consuming and lowers the pressure a bit, which I hope can speed up the process and make it more fun.

8.​

I hope to be every bit as precise in my thinking with this new format, but perhaps to relax a bit more about essay structure and completeness of "answers".

Introduction: What is Ordinary Language Philosophy​

I take Ordinary Language Philosophy ($OLP$) to be any philosophical program that claims that the problems of philosophy are best solved (or, in some cases, completely solved) by paying attention to ordinary language. As the Wittgenstein of Philosophical Investigations says:

Philosophical problems arise when language goes on holiday.

(Though Wittgenstein spawned an era of $OLP$, it is arguable whether he himself was a through-and-through $OLP$ philosopher.)

An example of tackling a philosophical problem using $OLP$ might be as follows. We might wonder "What is triangularity?" Sure we see triangles, but we don't "See triangularity". In comes the $OLP$ philosopher to insist that looking for a "thing that we see" in place of triangularity is a mistake. We should, they will say, pay attention to how we use the word in ordinary language, and we will see that we have made what Gilbert Ryle would call a category error in assuming that our singular term "triangularity" should refer to something like "That balloon" does. They will say that we can avoid being so misled by sticking to our ordinary language guns and not letting language "Go on holiday".

In this short note, I hope to outline where I think $OLP$ goes wrong and why, and also what it gets right. I will argue that $OLP$ is correct in the following points:

and I will argue that $OLP$ is incorrect and should be polished up in the following points:

I think $OLP$ is an immensely powerful tool and like all powerful tools, it is prone to overuse and misapplication. Although I once believed it, I have long since abandoned the idea that all philosophical problems can be resolved by appealing to ordinary language.

What Does Ordinary Language Philosophy Get Right?​

You can't get semantics before pragmatics. Don't look to the "Meaning", look to the use.​

We cannot pick the meanings of our words out of thin air. So much the worse for Carol's Humpty Dumpty. They depend on learning sets of concepts. It often seems like philosophers are doing this when particular philosophical puzzles arise. An example that tends to bother me is when philosophers fall prey to the notion that we can sort of "mean things at will". They do so when they say, for example, "Maybe the red I see is what you see when I see blue!" How exactly do we mean "red" in that sentence? In the same way that we learn how to use the word "red"! And, if that is the case, then it seems like I cannot be meaning it "in some other way at the same time" that presumably only I could understand. Or if I am, then that way of meaning that just sits flaccidly alongside the pragmatically efficacious one (the one that has cash-value of meaning in our actions) and isn't really a part of communicating with others.

It is as if when I uttered the word I cast a sidelong glance at the private sensation, as it were in order to say to myself: I know all right what I mean by it.

-- L. Wittgenstein, Philosophical Investigations $\S$ 274

I don't have preconceptual, in this case prelinguistic, knowledge of what "red" is and so how could I possibly mean something by it that is directly out of accord with the pragmatics of that concept (How I learned to apply it). I might as well say, "maybe the feeling I get when I take a bath is the same as the one you get when you have a toothache".

$OLP$ is correct to steer us away from these illusory meanings and the knotty philosophical problems that come with them. I think it is correct, not by virtue of the primacy of ordinary language, but by focusing on what it is that gives our expressions meaning in the first place.

Theoretical meanings have to be related somehow to pragmatic meanings or they are useless.​

When we are giving some kind of theory, predictive, descriptive, synoptic, or prescriptive, the theory will have no use to anyone if it is not tied to a concept that has pragmatic value to us. I think the free will issue is illustrative of this kind of divorce of theoretical meaning from pragmatic meaning. My typical argument with the determinist who acts like they are the first person to discover that the physical world of science is causally closed goes something like:

It should seem peculiar to us that "real choices", on the determinist's view, turn out to be just the sort we don't have. The pragmatics of what is and isn't a "choice" have gone entirely out the window and with them the notion of what we are talking about having any material consequence. And so the conversation will circle back to "What is a choice?" and the determinist and compatibilist will disagree on that. But why should we care about this particular determinist's definition of choice? It seems like they have a big "So what?" to answer for next if we accept it. When we divorce theoretical "choice" from what practices and actions we take in knowing and deploying the word "choice" in real life, what importance does the theory really have?

$OLP$ is correct to keep us on a slightly tighter leash than we sometimes want to be on when philosophizing. We need to stay somewhat tethered to the common-sense concepts if we want our philosophizing to pertain to them.

If meaning comes from use, then meanings will be an imprecise hodge-podge because "doing" and therefore "use" is an imprecise hodge-podge. This is why "conceptual analysis" has never successfully analyzed a concept in the history of philosophy.​

We should assign an extremely low probability to the possibility of 'fully analyzing a concept'. In an effort to make the concept precise and immune to counterexamples, we will confine the concept to a tiny playpen and thereby commit the mistake of divorcing the concept from the vast landscape of actions and practices that give it meaning at all. We either have a chaotic hodge-podge of a concept, a fragile one to counter-examples, or one so surgically defined that it simply has nothing to do with the concept we sought to elucidate in the first place. I believe accepting the hodge-podge is the best play here.

That doesn't mean we can never have precision in more tightly bounded domains. It only means that precision across the board in every practice and context, as the determinist above thinks that can have with "choice", will likely be impossible and should not be expected. If meaning is determined by what we do, and what we do changes, how can we expect to ever catch up?

If meanings come from uses, then they must follow rules. For communication to be possible, some normativity must be assumed.​

As Wittgenstein (under some interpretations) and Kripke point out, in their rule-following paradoxes, applying a concept properly, learning a word, following a rule cannot be something that is done all by oneself in a vacuum. Kripke asks us to imagine a rule for a mathematical function called quus. Quus, $⊕$, is just like 'plus', $+$, except:

$x⊕y = x+y$

if $x, y < 57$

but

$x⊕y = 5$

if $x, y > 57$

Suppose I have been teaching you to add all the way up until we have gotten to:

$57 + 57$

What should you answer? $5$? or $114$? The point of the strange example is that it seems like nothing about how I have taught you to add so far has determined whether I meant quus or plus. There is no fact of the matter. The same skeptical challenge could be applied to any rule and so it seems that without some turning of the spade and reaching justification for the rule, this could go on ad infinitum. We reach a sort of Agrippan trilemma of "rule following". It seems no rule can ever be justified merely by example or stipulation of how the rule should be followed because any action can be made to fit the rule and any rule made to fit my past actions. If we need rules for how to follow the rules, then how could a rule ever ground a practice? Wouldn't we then need "rules for following rules for following rules"?

I think the rule-following paradox terminates in doing. We don't learn rules by painstakingly memorizing instructions or "rules for following rules". It isn't that doing is a kind of justification. It is that we turn implicitly on certain hinges when we act. Our actions implicitly commit us to taking certain explicit, though not practically codifiable, claims to be the case. This is were the regress ends.

Someone says to me: "Show the children a game." I teach them gambling with dice, and the other says "I didn't mean that sort of game." Must the exclusion of the game with dice have come before his mind when he gave me the order?

-- L. Wittgenstein, Philosophical Investigations $\S$ 70

In this silly example, when the concerned parent says "Not that kind of game!" he didn't consult an inner rule or mental lookup-table of any kind in order to exclude gambling from the kind of games he meant. The meaning of the sentence and the rule that we were to follow was grounded in practice, in the pragmatic "doing of stuff", in habits and the innate nature of us as human beings.

Ordinary language is rough around the edges, does a million more things than state facts about the world, constantly changes, and is a reflection of what we do and what we fundamentally believe must be done. There is no playing the game of philosophy without language or concepts of some kind which set their roots in practice. Therefore, we have to philosophize while keeping in mind that those words and concepts are constructions of the practices and actions that give them meaning in the first place.

What Does Ordinary Language Philosophy Get Wrong?​

Ordinary use has no theoretical primacy. A term can grow to encompass more than its ordinary use.​

I am often frustrated reading $OLP$ philosophers say things like "This is a misuse of the word thought". I am all for taking the semantics as following the pragmatics. We cannot just mean whatever we want by words without getting the ball rolling through some kind of action in practice. If I want "thought" to mean "words I speak internally", then I am certainly allowed to adopt that as a technical term. It may not relate very well to the ordinary use of the word or concept, but maybe that isn't my goal in whatever particular mode of philosophizing I am doing.

$OLP$ philosophers have attacked neuroscientists' use of sentences like "The brain thinks X". They claim this is a misuse of "to think" as only persons can think. That's where the pragmatics come from they claim, and I agree. We learn to say "think" of someone based on how they are acting etc etc. However, I think it is silly to claim that this kind of metaphorical talk is "nonsense" full stop. We very frequently use intentional language as a proxy to quickly understand complex systems and that should stand on its own theoretical merit, not be judged by the stipulated authority of ordinary language.

What claims ordinary language sentences should/shouldn't,do/don't commit us to are not known implicitly. They must be accounted for theoretically.​

There seems to be a sentiment in $OLP$ that all philosophy should do is describe how terms are used. However, in reading some of these philosophers, Ryle particularly, I often noticed that they seemed to be doing a lot more than that. More specifically, I often notice that they argue for or take for granted certain theories of how we should account for a given way of speaking.

These supposed "mere descriptions" from $OLP$ philosophers are often just expedient theories of how something in the world works. Sometimes they are empirical and need evidence, sometimes they are empirical and don't need evidence (because they are so obvious), and sometimes they are synoptic/prescriptive accounts of how language should be viewed to work. Here's an example: Quine (another philosopher who puts pragmatics before semantics) gives the example of "sakes" as a word that takes the grammatical form of a singular term but does not refer to anything. There are no "sakes" to be accounted for. Did we automatically know that there weren't "sakes" by virtue of knowing how to say "for Pete's sake"? Is that question "nonsense"? Is Quine giving a theory of how our words should be viewed? I think he is and so is every $OLP$ philosopher who prompts us to focus on the ordinary use of a word to circumnavigate a philosophical problem. The theory is still a theory whether we got it from observations about ordinary language or from philosophical accounts after the fact. We cannot know all there is to know about the application of a concept merely by looking at its current use because that concept's application is a prescriptive, not a purely descriptive endeavor. Should we say "it is the same time here as on the moon" in a post-relativistic physics world? Ordinary use cannot give us the answer. In a sense, our concepts are in a constantly changing state. We are almost always engaging in some small amount of conceptual engineering every time we encounter a novel case. But don't get me wrong. I'm all in favor of eschewing "accounts of" something when the ordinary concepts will do just fine.

We don't know all the implications of our claims just by virtue of making or being disposed to make them. Additionally, we don't always know how the ordinary concepts we use hang together, or how they relate to one another. We can be masters of the concepts of "inference" and "belief" without ever having thought about how they relate.

The pragmatic move is a good move, but it does not instantaneously give us a correct and satisfactory account of how our terms work, how their use can be more technically refined, or how they do/should relate to the word as science tells us it exists.

Not all philosophical problems are dissolved in ordinary language as it evolves and keeps up with science.​

Even in $OLP$ with a strong adherence to not extending ordinary terms beyond their common use, it isn't clear to me why all philosophizing is off limits by virtue of it not having some property that ordinary language has. I'd agree with Wittgenstein that lots of philosophical problems arise from our "bewitchment by language" (non-referring singular terms being a good example), but it is far from clear to me that we can say all of them are.

Philosopher David Enoch has a very fun example to illustrate this. In Pulp Fiction, Vincent Vega and Jules Winnfield are having a little back-and-forth about why Jules doesn't eat pork.

So by that rationale, if a pig had a better personality, he would cease to be a filthy animal. Is that true?

Enoch points out that both speakers are clearly philosophizing. It seems wrong to me to say that they just crossed the precipice of sense and were talking nonsense to each other even though they thought they weren't. On the other hand, I do think it is possible to philosophize in vain by playing games with words that are too far gone from their practical application for the inferences we might validly make about them to have any relevance at all. I take philosophizing to be a general extension of the basic human discursive practice of making our commitments to certain claims clear, whether to ourselves or to one another. That's what Jules is doing, and that is what I am doing now.

A scientist who ceases for a moment to try to solve his questions in order to inquire instead why he poses them or whether they are the right questions to pose ceases for the time to be a scientist and becomes a philosopher.

Intro​

I have too frequently heard skepticism expressed toward the usefulness (or worse: the epistemic viability) of armchair theorizing. The term "Armchair" is usually meant in pejorative sense to indicate that no real work could be done that way. I choose to just lean in to the term. Whether or not we take armchair theorizing to include mathematics, computer science, and logic this skepticism is unwarranted. There are a few subclasses of armchair theorizing that are usually in the crosshairs of those eager to criticize it. These typically include ethics, cosmology, analytic philosophy, theoretical physics, and much more. Given the amount of silly theorizing that goes on, the existence of criticism is unsurprising. However, I still see most of this criticism fall flat even when the analysis itself is not valid or useful.

Here I will argue that if we are going to accept any type of pure conceptual analysis as necessarily "Garbage in, Garbage out", which we should, then we are then committed to accepting it as necessarily "Gold in, Gold out". If we are committed to "Gold in, Gold out", then it follows that armchair knowledge can be generated and that should not be surprising.

Additionally, I will argue that the armchair toolkit consists of many useful tools that are not exhaustively described by 'listing facts', but nevertheless are indispensable in the furtherance of knowledge.

Naive Pure Empiricism​

Can we really generate knowledge from the armchair? How is that possible? I have myself been struck with a mysterious feeling around this question. If knowledge is about the world in some sense, how could I just sit here and come up with some? This may be an intuition only shared by those whom William James referred to as "hard-nosed empiricists" and they are mostly the target of the arguments here.

Philosopher David Chapman holds such a "hard-nosed" view with the only field allowed to generate armchair knowledge being mathematics:

If it were only this tweet where I had heard this sentiment expressed, I would likely just ignore it and move on. Indeed I would like to believe this position to be a straw-man I have invented, but sadly I have met many individuals who share this view, some deeply and some only on a superficial intuitive level.

I would like to interpret this charitably as "Don't speculate or try to reason abstractly too much about something that is best left to the domain of empirical research.", or maybe "We need SOME empirical content somewhere along the line to generate knowledge." I mostly agree with those and the second is something even most die-hard rationalists might accept. Chapman's words here invite a much stronger interpretation, even if maybe they are hyperbole. They espouse what I'll call Pure Naive Empiricism.

Let's slightly reformulate these claims while sticking to their cash-value as the formulation of Pure Naive Empiricism:

This claim is obviously false unless we adopt a rather extreme interpretation of what "empirical experiments" are. Pure Naive Empiricism appears to be a popular position among those not fond of abstraction that impinges on reality too closely. It would be a simple world if math and observations were all we needed for furthering knowledge.

Why is Pure Naive Empiricism entitled to stop at mathematics? (even if it is "mathematics plus some other stuff") If mathematics is an "acceptable" epistemic pursuit then why is formal reasoning about cosmology, ethics, metaphysics, or mind not? I suspect the Pure Naive Empiricist does not have a satisfactory answer to this question. We don't need to go poke anything to find out why either.

I will argue that there is no viable place to draw the line between "acceptable" and "not acceptable" analysis and so the distinction is bogus. Either all conceptual analysis of any kind (including mathematics) is capable of generating knowledge, if the premises are true and the rules are followed, or none of it is.

'Garbage In, Garbage Out' Implies 'Gold In, Gold Out'​

In learning elementary symbolic logic and my first programming languages I was taught a simple maxim of any deduction: "Garbage in, Garbage out." I believe this should uncontroversially apply to any formal language and indeed to everyday human languages in formulating and assessing arguments. Consider the following argument.

This is a valid argument but not a sound one. Nobody will ever care that Skrump is a Schmorg because it is a Blorg. We fed garbage in and we got garbage out.

What was not taught to me alongside this was "Gold in, Gold out". We usually don't have good reasons to care about this one because it is so obviously true. If we are writing a simple Python script that converts Celsius to Fahrenheit, we already know, trivially, that if it is 35^oC outside and my script says that converts to 95^oF, that this fact applies to the real temperature outside right now. We usually only need to be reminded of "Garbage in, Garbage out" when our analytical processes have generated an absurdity that we become convinced is true.

If the falsehood of at least one premise guarantees that a valid argument is not sound then all the premises truths guarantee that the argument is sound. We cannot rationally hold "Garbage in, Garbage out" without holding "Gold in, Gold out". If we have to hold both, then we cannot deny that the products of analysis are true. So, straightforwardly, if something is true and we have good reasons to believe it without other defeating reasons, we have knowledge.

If Armchair Knowledge Were Not Possible?​

Pure Naive Empiricism has extremely bizarre implications. For example, if all knowledge were generated solely by empirical experiments then we would have to know all of the conclusions entailed by our current beliefs, both the actual and conditional implications. We clearly don't know those. So either we claim that those somehow "are not knowledge" or we admit that Pure Naive Empiricism is a ridiculous view.

If armchair knowledge were not possible, how would we know what questions to ask to guide empirical inquiry? Should we be looking for consciousness in the brain? Do thoughts have a location? Can actual infinities exist? Could the universe be fundamentally random? Does it follow from space-time theory that space and time are not ontologically distinct? Is math real? Is everything we believe false because we only evolved to survive? Are these good questions at all? To find out if these questions are worth pursuing, we need armchair theorizing, even if it is speculative. We need to know that "this is the right/wrong question". The alternative is literally conducting an experiment to test every absurd hypothesis that we can come up with. Armchair theory, even speculative theory, can and does save us eons of unneeded experimentation.

Additionally, it is often overlooked by the Pure Naive Empiricist that not all knowledge-pursuing consists in the gathering of facts, deductively generated or discovered. We need to know the right questions and the right way to think about them to have success in any inquiry. Some ant colonies are complex systems whose behavior is best understood emergently. No listing of simple facts about these ants by itself, without the analytical armchair toolkit, would give us this insight.

What Armchair Theorizing Gets Wrong​

Some armchair theorizing is not worth the mental energy spent on it. If armchair knowledge can be knowledge at all, then it can be true, but what kind of armchair knowledge is useful? We should answer this question partially with reference to the two maxims above. I can say that I know that if "All Blorgs are Schmorgs and Skrump is a Blorg" then "Skrump is a Schmorg" but it is clearly of zero use whatsoever. The concepts we reason about, if we want to generate not only knowledge but knowledge that matters, must be clear and serve some end.

If we have some valid reasoning about minds, it is only as useful as the argument's concept of "minds" is related to the one(s) that we actually use. If we say minds are in rocks and atoms as well as in brains, then are we still talking about the same content anymore or have we made a move that makes our terms devoid of any of the predictive or explanatory power that made them useful? Perhaps in the future we will have some other theoretical reasons to shift the semantic ground away from the folk-concept of "minds".

Generally, we should be skeptical of armchair theorizing that overextends concepts beyond the scope of their reasonable usefulness. When that limit has been overreached is itself often a tricky philosophical question. Some philosophers believe that the Einsteinian notion of space-time should be scrapped because of analytic arguments about how time must be ontologically distinct from space. Though I cannot rule out these conclusions as false with a hand wave, we should be skeptical when armchair thinking has purportedly overturned a useful empirical framework.

What Can Armchair Theorizing Do?​

Every implication of our current beliefs, conceptual definitions, and strategies of inquiry is not laid bare before us just by having them. If that were the case, we would be supercomputers. That space needs to be mapped out and the edges of the map keep expanding. Useful armchair theory is not all pure deduction, sometimes it takes the form of reframing questions, guiding inquiry, and using the power of analogy to deepen understanding or see new possibilities. All of these modes and many more are indispensable to science and to good human lives.

Generally, useful armchair theory comes in the form of deductive arguments, clarifications of existing concepts, demonstrating the incompatibility of certain beliefs, the dispelling of illusory problems, the creation of new questions, meta-inquiry, and the discovery of unforeseen implications of currently known truths.

Conclusion​

I hope I have made it clear that outright denial of the possibility of non-experimental knowledge or 'armchair knowledge' is absurd. I have argued that it is irrational to reject the ability of analytical reasoning to generate knowledge and that it is wrong to limit the scope of the furtherance of knowledge to mere 'fact collection'. I think that the intuitions to the contrary are motivated by putting empirical inquiry on a pedestal while taking for granted the foundations that support it.

The analytic toolkit that can be accessed from the armchair cannot reach out and interface with the physical world, of course, but it simply does not need to in order to be useful, generate truth, and make lives better.
