The Philosophy of Commensurablism

In this essay I will lay out what my general philosophical views are, and my reasons for holding them, before I begin diving into the details of the implications of them on other broad approaches to philosophy, and on the many narrow subtopics of philosophy, in subsequent essays.

This essay will begin with discussion of some extremely basic, hopefully uncontroversial, and potentially boring aspects of any kind of activity or discourse, but build from those boring basics up to a strong and likely controversial stance amidst various other philosophical possibilities. For as Bertrand Russell wrote, "The point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it."

I will first spend some time detailing exactly what position it is that I am going to argue for, in nuanced detail to make sure that there are no misunderstandings, before I then give an argument for it. Then I will explore the general implications of that position on different areas of philosophy in broad strokes, and finally compare and contrast that position to a number of others of comparable scope.


Whenever we find ourselves trying to do anything at all, trying to make some state of affairs or another the case, there are always two questions it behooves us to ask:

But the answers to each of these kinds of questions can prompt more questions of the same kind in return. And as those chains of answers and further questions careen off toward infinity, we can begin to wonder how or even if there can ever be found ultimate answers to ground those chains of questions, in either direction. In a way, all of philosophy stems from wrestling with the discomforting prospect of these infinities, as daunting questions arise about both what if anything there really is at all, and how it came to be, and also what if anything there morally ought to be at all, and why it should be that way.

At least initially, it seems that, regarding both of these matters:

But whether that continues to be the case comes into question as soon as we communicate with, or even imagine the possibility of, other people who have different experiences or come to different conclusions. We are forced to confront the possibility that our opinions might be incorrect, and that there might be more to whatever is correct than just what we personally experience.

At least for the most immediate questions of both of those types – how did, or why should, this in particular become the case, just in terms of an immediate cause or purpose – we tend to argue as though:

If we didn't think both of those things, then we wouldn't be arguing in the first place, as there would be no point if nobody was correct or incorrect at all, or if there weren't any question as to who it was.

The core of my general philosophy, for which I will argue in a moment, is that those two basic premises implied in every normal argument should always be treated as correct, even as the chains of subsequent questions careen off to infinity and big philosophical issues rear their heads, because either "I'm just right and you're just wrong" (supposing that some answers are unquestionable) or "there’s no such thing as right or wrong" (supposing that some questions are unanswerable) are nothing but lazy ways to dodge the argument, avoiding the potential of having to change our opinions, and so cutting us off from all potential to learn and so improve our opinions.

And I find that those two basic premises implied in every normal argument actually reinforce, rather than undermine, the starting assumptions that everyone is free to come to their own conclusion, and that there is nothing to go off of but experiences. For as I will elaborate momentarily, denying the former would end up tantamount to saying "there’s no such thing as right or wrong", and denying the latter would end up tantamount to saying "I'm just right and you're just wrong".

So my general philosophy could be most succinctly summed up as the rejection of both unquestionable answers (answers that are not to be questioned), and unanswerable questions (questions that cannot be answered). By this I mean trusting that there are answers to be had, but always questioning every proposed answer; and entertaining the possibility of anything that might be an answer, but rejecting anything that's beyond questioning.

Four Core Principles

In other words, I hold that, for all meaningful questions:

  • There is such a thing as a correct opinion, in a sense beyond mere subjective agreement. (A position I call "universalism", and its negation "relativism".)
  • There is always a question as to which opinion, and whether or to what extent any opinion, is correct. (A position I call "criticism", and its negation "dogmatism".)

These in turn entail, for reasons I will elaborate momentarily, that:

  • The initial state of inquiry is one of several opinions competing as equal candidates, none either winning or losing out by default, but each remaining a live possibility until it is shown to be worse than the others. (A position I call "liberalism", and its negation "cynicism").
  • Such a contest of opinion is to be settled by comparing and measuring the candidates against the common scale of the experiential phenomena accessible by everyone, and opinions that cannot be thus tested are thereby disqualified. (A position I call "phenomenalism", and its negation "transcendentalism".)
Philosophical spectrum

I group these principles together as alternate types of four broader categories:

  • "Objectivism" is what I name the broader category that encompasses both:
    • universalism (which I support), and
    • transcendentalism (which I oppose).
  • "Subjectivism" is what I name the broader category that encompasses both:
  • "Fideism" is what I name the broader category that encompasses both:
  • "Skepticism" is what I name the broader category that encompasses both:

(Henceforth I will use each of these terms in these specific senses only, to have clear labels for these positions. I am aware that many of these terms have uses other than the ones I am putting them to here, e.g. "objectivism" being used as the name of Ayn Rand's philosophy and "liberalism" being used in a variety of different political ways, and unless specifically mentioned I do not mean to imply any association with those usages where they differ from these ones).

Commensurablism

Phenomenalism, as anti-transcendentalism, is entailed by criticism, or anti-dogmatism: if we are going to hold every opinion open to question, we have to consider only opinions that would make some experiential, phenomenal difference, where we could somehow tell if they were correct or incorrect. (At least, unless we're willing to also reject universalism for relativism, and say that there are some questions about things beyond experience that simply can never be objectively answered. But as relativism itself also entails phenomenalism – for if there can be no apprehension of the objective then we have only subjective appearances to go on – we are still left with phenomenalism in any case.)

And liberalism, as anti-cynicism, is entailed by universalism, or anti-relativism: if we are going to hold that such a thing as a correct opinion is possible, we have to give every opinion the benefit of the doubt that that one might possibly be it, otherwise we would be forced to dismiss all opinions as equally incorrect out of hand. (At least, unless we're willing to also reject criticism for dogmatism, and say that there are simply some foundational opinions that are beyond question. But as dogmatism itself also entails liberalism – for to take anything on faith we must suspend skeptical questioning – we are still left with liberalism in any case.)

Because of this, "criticism" and "universalism" are enough to summarize my entire general philosophy, and it would suffice to name that general philosophy "critical universalism" or "universalist criticism".

However I prefer a different, more succinct name: "commensurablism". For two things to be commensurable is for there to be some way to compare and measure them against each other, and I call my philosophy "commensurablism" because, all of the above taken into account together, its defining feature is that opinions of any sort can be compared and measured against each other to see which is more or less correct than the other.


These core principles of commensurablism apply equally to both descriptive questions about reality, and prescriptive questions about morality, but some of them are more familiar under different names on different sides of that divide:

  • Universalism about reality is usually just called "realism", while universalism about morality might likewise be called "moralism": one holds that some things are actually real, and the other that some things are actually moral, neither is just mere opinion.
  • Similarly, phenomenalism about reality is usually called "empiricism", while phenomenalism about morality is usually called "hedonism": one appeals to sense experiences for descriptive justification, while the other appeals to appetitive experiences for prescriptive justification.
  • And a combination of the principles of criticism and liberalism to investigations of descriptive questions is usually called a "critical" philosophy of knowledge, while that same combination of principles applied to investigations of prescriptive questions is usually called a "liberal" philosophy of justice.

On Reality, Truth, and Knowledge

With regards to opinions about reality, commensurablism boils down to forming initial opinions on the basis that something, loosely speaking, looks true (and not false), and then rejecting that and finding some other opinion to replace it with if someone should come across some circumstance wherein it looks false in some way.

And, if two contrary things both look true or false in different ways or to different people or under different circumstances, commensurablism means taking into account all the different ways that things look to different people in different circumstances, and coming up with something new that looks true (and not false) to everyone in every way in every circumstance, at least those that we've considered so far.

In the limit, if we could consider absolutely every way that absolutely everything looked to absolutely everyone in absolutely every circumstance, whatever still looked true across all of that would be the universal truth.

In short, the universal truth is the limit of what still seems true upon further and further investigation. We can't ever reach that limit, but that is the direction in which to improve our opinions about reality, towards more and more correct ones. Figuring out what can still be said to look true when more and more of that is accounted for may be increasingly difficult, but that is the task at hand if we care at all about the truth.

(It is trivially simple to satisfy everyone's different sensations with a theory that we’re all in different virtual worlds being fed different experiences, but theories that involve us all being in the same world together get trickier).

This commensurablist approach to reality may be called "critical empirical realism", as realism is the descriptive face of universalism, empiricism is the descriptive face of phenomenalism, and what I would call a critical-liberal methodology is more commonly called just "critical" as applied to theories of knowledge.

On Morality, Goodness, and Justice

With regards to opinions about morality, commensurablism boils down to forming initial opinions on the basis that something, loosely speaking, feels good (and not bad), and then rejecting that and finding some other opinion to replace it with if someone should come across some circumstance wherein it feels bad in some way.

And, if two contrary things both feel good or bad in different ways or to different people or under different circumstances, commensurablism means taking into account all the different ways that things feel to different people in different circumstances, and coming up with something new that feels good (and not bad) to everyone in every way in every circumstance, at least those that we've considered so far.

In the limit, if we could consider absolutely every way that absolutely everything felt to absolutely everyone in absolutely every circumstance, whatever still felt good across all of that would be the universal good.

In short, the universal good is the limit of what still seems good upon further and further investigation. We can't ever reach that limit, but that is the direction in which to improve our opinions about morality, toward more and more correct ones. Figuring out what what can still be said to feel good when more and more of that is accounted for may be increasingly difficult, but that is the task at hand if we care at all about the good.

(It is trivially simple to satisfy everyone's different appetites with a strategy to put us all in different virtual worlds and feed us different experiences, but strategies that involve us all being in the same world together get trickier).

This commensurablist approach to morality may be called "liberal hedonic moralism", as moralism is the prescriptive face of universalism, hedonism is the prescriptive face of phenomenalism, and what I would call a critical-liberal methodology is more commonly called just "liberal" as applied to theories of justice.


Pragmatic Justification

The underlying reason I hold this general philosophical view, or rather my reason for rejecting the views opposite of it, is my metaphilosophy of analytic pragmatism, taking a practical approach to philosophy and how best to accomplish the task it is aiming to do. To recap, that task is to find a way of discerning correct answers from incorrect answers to questions of any kind, whether about what is real or true or existent, or about what is moral or good or valuable.

As commensurablism is just the conjunction of criticism and universalism, which are in turn just the negations of dogmatism and relativism, respectively, the core argument for it is thus to argue against both of those, on the pragmatic grounds that either of them completely undermines the possibility of doing that task of discerning correct answers from incorrect ones:

  • If we accept dogmatism rather than criticism, then if our opinions should happen to be incorrect, we will never find out, because we never question them, and we will remain incorrect forever.
  • If we accept relativism rather than universalism, then if there is such a thing as the correct opinion after all, we will never find it, because we never even attempt to answer what it might be, and we will remain incorrect forever.

There might not be such a thing as as an objectively correct opinion, and even if there is, we might not be able to find it any more reliably than a shot in the dark of blind faith. But if we're starting from such a place of complete ignorance that we're not even sure about that – where we don't know what there is to know, or how to know it, or if we can know it at all, or if there is even anything at all to be known – and we want to figure out what the correct opinions are in case such a thing should turn out to be possible, then the safest bet, pragmatically speaking, is to proceed under the assumption that there are such things, and that we can find them, and then try. Maybe ultimately in vain, but that's better than definitely failing just because we never tried in the first place.


To now summarize the argument for the entirety of commensurablism, that we have already worked backward through above:

  • The task of philosophy is to find a way of discerning correct answers from incorrect answers to questions of any kind, whether about what is real or true or existent, or about what is moral or good or valuable.

  • The position that there is such a thing as a correct opinion, in a sense beyond mere subjective agreement, is to be called "universalism", and its negation "relativism".
  • If we assume relativism rather than universalism, then in case there does happen to be such a thing as the correct opinion after all, we will never find it, because we never even attempt to answer what it might be, and we will remain incorrect forever.
  • Therefore to successfully do philosophy at all we must at least tacitly assume universalism, rejecting relativism.

  • The position that there is always a question as to which opinion, and whether or to what extent any opinion, is correct, is to be called "criticism", and its negation "dogmatism".
  • If we assume dogmatism rather than criticism, then in case our opinions do happen to be incorrect after all, we will never find out, because we never question them, and we will remain incorrect forever.
  • Therefore to successfully do philosophy at all we must at least tacitly assume criticism, rejecting dogmatism.

  • The position that the initial state of inquiry is one of several opinions competing as equal candidates, none either winning or losing out by default, but each remaining a live possibility until it is shown to be worse than the others, is to be called "liberalism", and its negation "cynicism".
  • Liberalism is entailed by universalism: if we are going to hold that such a thing as a correct opinion is possible, we have to give every opinion the benefit of the doubt that that one might possibly be it, otherwise we would be forced to dismiss all opinions as equally incorrect out of hand.
  • Therefore, since to successfully do philosophy at all we must at least tacitly assume universalism, rejecting relativism, we must likewise at least tacitly assume liberalism, rejecting cynicism.

  • The position that any contest of opinion is to be settled by comparing and measuring the candidates against the common scale of the experiential phenomena accessible by everyone, and opinions that cannot be thus tested are thereby disqualified, is to be called "phenomenalism", and its negation "transcendentalism".
  • Phenomenalism is entailed by criticism: if we are going to hold every opinion open to question, we have to consider only opinions that would make some experiential, phenomenal difference, where we could somehow tell if they were correct or incorrect.
  • Therefore, since to successfully do philosophy at all we must at least tacitly assume criticism, rejecting dogmatism, we must likewise at least tacitly assume phenomenalism, rejecting transcendentalism.

  • Therefore to successfully do philosophy at all, to find any way of discerning correct answers from incorrect answers, we must at least tacitly assume universalism, criticism, liberalism, and phenomenalism; rejecting relativism, dogmatism, cynicism, and transcendentalism.

This line of argument bears similarities to Blaise Pascal's "Wager", or pragmatic argument for believing in God. In the Wager, Pascal argues that if we cannot know whether or not God exists, we nevertheless cannot help but act on a tacit opinion one way or another, by either worshipping him or not. This results in four possible outcomes:

  • either we believe in God, and he doesn't exist, and we lose a little in the wasted effort of worship;
  • or we disbelieve in God, and he doesn't exist, and we save what little effort we would have spent in worship;
  • or we believe in God, and he does exist, and we reap the infinite reward that is heaven;
  • or we disbelieve in God, and he does exist, and we suffer the infinite loss that is hell.

Pascal argues that it is thus the practically safest bet to believe in God, whether or not he turns out to actually exist. My pragmatic argument for commensurablism bears a formal similarity to that, in that I am likewise arguing that if we cannot know whether there are answers to our questions to be found, we nevertheless cannot help but act on a tacit opinion one way or another, by either trying to find them or not, resulting again in four possible categories of outcome:

  • either we try to find the answers, and there are none that we could possibly find, and we lose the wasted effort of investigation;
  • or we don't try to find the answers, and there are none that we could possibly find, and we save what effort we would have spent in investigation;
  • or we try to find the answers, and there are some that we could find, and we reap the reward that is having them;
  • or we don't try to find the answers, and there are some that we could find, and we suffer the loss that is never having them.

Of course, exactly how much effort is wasted or saved depends on how much effort we would expend, and how much loss we suffer or reward we reap depends on what is at stake, and those factors change the exact odds of such a "wager". But as we can vary how much effort we expend at will, and there is always something at stake since everything we ever do depends upon the answers to the questions of how and why to do it, there is always some amount of effort for which the odds work out in favor of at least trying to figure things out, and it is never pragmatic to simply give up completely, as assuming either dogmatism or relativism would entail.

The important key difference between Pascal's Wager and mine is that Pascal urges us to "bet" on one specific possibility, when there are many different possibilities with similar odds – different religions to choose from, different supposed Gods to worship and ways to worship them – leaving one forced to choose blindly which of those many options to bet on, and necessarily taking the worse option on all the other bets. Whereas I am only urging one to "bet" at all, to try something, anything, many different things, and at least see if any of them pan out, rather than just trying nothing and guaranteeing failure.

To analogize the respective "wagers" to literal wagers on a horse race: Pascal is urging us to bet on a specific horse winning, rather than losing, while I am only urging us to bet on there being a bet at all, rather than not. If there is no bet, then we cannot lose the non-existent bet by betting in that non-existent bet that there will be a bet, even though we still might not win either, if there is indeed no bet to win.

I would argue that to do otherwise than to try (even if ultimately in vain) to find answers to our questions, to fall prey to either relativism or dogmatism, to deny that there are such things as correct or incorrect opinions about either reality or morality, or to deny that we are able to figure out which is which, is actually not even philosophy at all.

The Greek root of the word "philosophy" means "the love of wisdom", but I would argue that any approach substantially different from what I have laid out here as commensurablism would be better called "phobosophy", meaning "the fear of wisdom". For rather than seeking after wisdom, seeking after the ability to discern true from false or good from bad, it avoids it, by saying either that it is unobtainable, as the relativist does, or that it is unneeded, as the dogmatist does.

Commensurablism could thus be said to be necessitated merely by being practical about the very task that defines philosophy itself. If you're trying to do philosophy at all, to pursue wisdom, the ability to sort out the true from the false and the good from the bad, you end up having to adopt commensurablism, or else just give up on the attempt completely, dismissing it as either hopeless or useless.

As Henri Poincaré rightly said, To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection. Or as Alfred Korzybski similarly said, There are two ways to slide easily through life: to believe everything or to doubt everything; both ways save us from thinking.

Roughly Spiral Progress

Thus all of inquiry, on either factual or normative matters, is an unending process of trying to filter out opinions that we have reasons to think are the wrong ones, and to come up with new ones that still might be the right ones. But no matter your current best answer to either question, there is always some degree of uncertainty: you might be right, but you might be wrong. All we can do is narrow in further and further on less and less wrong answers.

In a way this is somewhat comparable to the "spiral-shaped" progress described by philosophers such as Johanne Fichte and Georg Hegel. Imagine an abstract space of possible answers, with the correct answers lying most likely somewhere around the middle of that space. Our investigations whittle away further and further at all opposite extremes, theses and their antitheses, and then again at the remaining extremes of the resulting syntheses, again and again, indefinitely. The center of the area remaining after each step will consequently wander around the original complete space of possibilities in a manner that gradually "spirals", roughly speaking, closer and closer to wherever the correct answer is in that space.

Fichte and Hegel's "spiral-shaped progress" of theses, antitheses, and syntheses is, I think, a bit too much an idealization of this process, but it is at least in the right general direction relative to its predecessors, in a way that is itself an illustration of this very process:

Eliminating first the extremes, the thesis and antithesis, of viewing worldviews either as constant and static, or as progressing linearly in a given direction, a first approximation at a synthesis could be the notion of circular change, alternating between opposites in a constant pattern. Hegel's notion of spiral progress is a further refinement upon that, a synthesis between linear progress and circular change, a view of alternating between opposites but narrowing in constantly toward some limit.

My view is a refinement further still, which can perhaps be framed as the synthesis of Hegel's view, and the view that there is no pattern at all to change, just random or at least chaotic, unpredictable change. In my view the changes of worldview are largely unpredictable and unstructured, but by constantly weeding out the untenable extremes, the chaotic swinging between ever-less-extreme opposites still tends generally toward some limit over time.

Commensurablism is itself explicitly such a synthesis of opposing views. As described already in the introduction, the history of philosophy is itself a series of diverging theses and antitheses punctuated by unifying syntheses, and I aim to position this philosophy as a synthesis of the contemporary pair of thesis and antithesis in that series, Analytic and Continental philosophy.

It is furthermore a synthesis of two opposing trends in general public thought that I observe in my contemporary culture, that very loosely track affinity to those professional philosophical schools. One of them places utmost emphasis on the physical sciences and the elite academic authorities thereof, largely denying the universality of morality entirety. The other places their utmost emphasis on the ethical and political authority of the general populace, while largely denying the universality of reality entirely.

But each of the faults of each of those trends of thought stem ultimately from haphazardly falling one way or another into one of the two worldviews that commensurablism is most truly a synthesis of: fideist objectivism and skeptical subjectivism. I aim to adapt and shore up the strengths of each of those opposing views, while rejecting those parts of each against which the other has sound arguments, resulting in this new view that retains the best of both and the worst of neither, being critical yet universalist about both reality and morality.

The Opposition

Some philosophers, such as Ludwig Wittgenstein, end up advocating what is called a "quietism" about philosophy by the time they reach the end of their own philosophizing. A quietism about philosophy is the view that there is nothing positive to say on the topic of philosophy, only things to say about what not to do, and so once some philosopher has spoken against the errors that are commonly made by all other philosophers, there is nothing more to say about philosophy: after that, philosophy should not be done anymore, because to say anything else would only be to philosophize badly.

I think that philosophy is no different than any other topic in that respect. Critical-liberal methods as I've already advocated above mean that all you're ever justified in saying on any topic is that the answer to a question is not within a certain range of possibilities, only ever saying that it must be in some range or another to the extent that that is just a rephrasing of saying what range it must not be within. In theology, this "negative way" is sometimes called "apophatic" – when theologians speak only of what God is not like, rather than saying anything about how they think he positively is – and that term is sometimes extended to label philosophical approaches like this as well.

Yet as already elaborated above, it is always still a range of possibilities that remains, a range that can always be further narrowed, a single exact answer never conclusively pinned down. Consequently, as much can still be said on the topic of philosophy as can be said on any other topic, as the process of narrowing down the possible answers – elaborating on what answers are not possible, as an apophatic philosopher sets out to do – continues indefinitely, never being finished.

So unlike a quietist philosopher, I have no illusions that my work here – even if entirely correct – should be the last word. And if this work outlives me, I encourage the people of the future to refine and expand upon it, as I have no doubt will be necessary.

But like a quietist philosopher, I do think that philosophy done well is largely if not entirely apophatic, about explaining the ways that philosophy may be done poorly, and why those ways are poor. To that end, before I get into any of my more specific views on the various sub-topics of philosophy, I must elaborate further on the broad ways in which I think philosophy is commonly done wrongly.


Principles and Counter-Principles of Commensurablism

My phenomenalism may superficially sound similar to relativism (both being kinds of subjectivism), inasmuch as there being nothing more to things than their experiential qualities sounds superficially similar to there being no actual things at all, only the appearance of them. Conversely, my universalism may sound like it could entail transcendentalism (both being kinds of objectivism), for the same reasons but in reverse.

Likewise, my liberalism may superficially sound similar to dogmatism (both being kinds of fideism), inasmuch as not requiring justification to hold an opinion sounds superficially similar to leaving some opinions beyond question. Conversely, my criticism may sound like it could entail cynicism (both being kinds of skepticism), for the same reasons but in reverse.

This conflation of similar but importantly distinct principles – objectivisms (transcendent or merely universal), subjectivisms (relativistic or merely phenomenal), skepticisms (cynical or merely critical), and fideisms (dogmatic or merely liberal) – leads many people, I suspect, to see the only available options as a transcendent dogmatic view, or else a cynical relativist view:

Phobosophies

Those who reject dogmatism, as I do, and correctly adopt its negation, criticism, but wrongly equate liberalism with dogmatism and thus criticism with cynicism, then correctly see that cynicism entails relativism, and so conclude that the only alternative to dogmatism is relativism. If they likewise correctly see that rejecting dogmatism entails rejecting transcendentalism, but wrongly equate universalism with transcendentalism and thus phenomenalism with relativism, they will likewise conclude that the only alternative to dogmatism is relativism. In either case, from their correct rejection of dogmatism, they find themselves seemingly but wrongly compelled to adopt relativism.

Those who reject relativism, as I do, and correctly adopt its negation, universalism, but wrongly equate phenomenalism with relativism and thus universalism with transcendentalism, then correctly see that transcendentalism entails dogmatism, and so conclude that the only alternative to relativism is dogmatism. If they likewise correctly see that rejecting relativism entails rejecting cynicism, but wrongly equate criticism with cynicism and thus liberalism with dogmatism, they will likewise conclude that the only alternative to relativism is dogmatism. In either case, from their correct rejection of relativism, they find themselves seemingly but wrongly compelled to adopt dogmatism.

Incommensurablism

Much worse still than either of those, though, is the nonsense that comes when both universalism and criticism are rejected together: saying that nothing is objectively true, like a relativist, but then, rather than skeptically rejecting all claims, instead taking that to make all claims immune to skepticism, like a dogmatist, because they couldn't be objectively wrong either. This makes for a relativism that gives free reign to all forms of dogmatism, and a dogmatism that cloaks itself in relativistic armor.

This forms a kind of bizarro-commensurablism, in that it's also positioning itself between cynical relativism and transcendent dogmatism, but in a way that adopts the worst of each rather than the best of each, completely inverting all of the principles of commensurablism. But even those who support this position are not completely misguided. I think they're merely neglecting to differentiate between similar but importantly distinct positions, and so ignoring some possibilities that would accomplish the ends I suspect they have in mind without the pitfalls that they end up in.

I suspect that, just like me, they start from a place of objectivism and skepticism, and then, just like me, they reach subjective and fideistic conclusions from there. But they take objectivism to mean transcendentalism, rather than merely universalism as I do; and they take skepticism to mean cynicism, rather than merely criticism as I do. That is to say, they take what is objective to mean whatever is beyond any mere appearances (rather than just according with all appearances, as I do), and they take being skeptical to mean rejecting everything we don't have solid reasons to accept (rather than just rejecting anything we do have solid reasons to reject, as I do).

They therefore infer – validly, from the assumption of those incorrect premises – that there can be no apprehension of what is objective, and that all we have to go on is the subjective appearances of things, about which we are all equally free to think as we like, without having to answer to anyone's questioning. That conclusion does implicitly include within it my own principles of subjectivism-qua-phenomenalism and fideism-qua-liberalism; and I think that my endorsement of those principles should be enough to satisfy their concerns with my endorsement of objectivism-qua-universalism and skepticism-qua-criticism. But the transcendental and cynical premises they start from demand they take it further than that, into fideism-qua-dogmatism (as in, there are no grounds on which to ever call anybody's opinions wrong) and subjectivism-qua-relativism (as in, there are no grounds on which to ever suppose any opinion might be right).

But as those principles we end up agreeing on, liberalism and phenomenalism, are the negations of their own cynical and transcendentalist premises, this entire line of reasoning ends up logically incoherent, unless they then reject the very premises they started from, and stick only with the now-unsupported conclusions. The conclusion of liberalism (entailed by their dogmatism) negates the premise of cynicism, which then undermines the argument for relativism, though that does not automatically disprove relativism. Likewise the conclusion of phenomenalism (entailed by that relativism) negates the premise of transcendentalism, which then undermines the argument for dogmatism, though that does not automatically disprove dogmatism.

It is still logically possible to be a liberal phenomenalist, like we both are, without being a critical universalist, like I am and they are not; it is logically possible to be a liberal phenomenalist and also a dogmatic relativist, and all dogmatic relativists logically must also be liberal phenomenalists (though not vice versa). But then, as the premises of their arguments against criticism and univeralism, in favor of dogmatism and relativism, have been undermined by their own subsequent conclusions, we circle back around to the pragmatic reasons to assume criticism and universalism whenever we're unsure if they're correct or not, as laid out earlier in this essay: because to do otherwise is just to give up trying. And those principles together jointly entail the same phenomenalism and liberalism that they already endorse, without stalling out all hope of progress as either dogmatism or relativism would.

That lack of hope of progress is the greatest threat of this last position. It treats everything as meaningless, because it allows no possibilities for anything to be either right or wrong, in either a descriptive or a prescriptive sense. And in doing so it shuts down all discourse about the merits, pro or con, of one opinion versus another, leaving everyone to merely have whatever opinions they happen to have and never sort out if there are any reasons to adopt one over the other.

This last position of dogmatic relativism bears many of the hallmarks of a type of view sometimes called "Postmodernism". But because that is, perhaps intentionally, a very vague and poorly-defined category, defined less by any of its own core principles and more in reference to a historical period in which the things it's opposed to were more common, I prefer instead to call it “incommensurablism”, and the supposed "Modernism" that it opposes "transcommensurablism".

For incommensurablism's defining tenet is precisely the opposite of commensurablism's: no opinions of any sort can be compared or measured against each other to see which is more or less correct than the other. But the position that its arguments actually target to reach that conclusion is not that of commensurablism, but instead the position beyond commensurablism at the opposite extremes, of transcendental cynicism, where the incommensurablists themselves started.


As just detailed, I think that all of these positions I end up disagreeing with start from notions that I agree are generally in the right direction: some kind of objectivism or skepticism, which then respectively entail some kind of fideism and subjectivism. There are multiple ways of resolving the apparent conflicts that then arise. Some side with objectivism and fideism over skepticism and subjectivism; some side the opposite way; and some either just side with fideism and subjectivism over skepticism and objectivism, or else try to side with the latter so overzealously (for who wouldn't want absolute certainty about things beyond all appearances, if that were a coherent possibility) that they find themselves thereby forced into the former anyway. And in all those cases, at least some if not all of those reasonable starting notions end up discarded along the way.

As in the Dogen quote in the introduction, before one studies philosophy, things make a naive kind of sense; then after an initial foray into philosophy, everything is turned on its head, into one form of nonsense or another. What I'm trying to build here in commensurablism is a way out of that nonsense, back into a more mature version of those reasonable starting positions, that can better withstand the temptation of such nonsense, and to show the common error underlying all of those different deviations from that initial core of common sense that we all start from.

And what all of those responses share in common is the conflation of different types of objectivism (transcendent or merely universal), subjectivism (relativistic or merely phenomenal), skepticism (cynical or merely critical), and fideism (dogmatic or merely liberal) together. But they need not be so conflated.

A universalist phenomenalism is not relativistic, and a phenomenalist universalism is not transcendent, viewing the world as wholly independent of anyone's opinions about it, but in no part inaccessible to all experience of it. Likewise a critical liberalism is not dogmatic, and a liberal criticism is not cynical, viewing the search for answers as an ongoing narrowing-down from initially unlimited possibilities, not the attempt to construct absolute certainties built upon foundations that themselves rest ultimately on nothing.

The differentiation of those superficial similarities, and so the opening up of possibilities besides those extremes detailed above, is the key insight at the core of my entire general philosophy, embracing:

  • universalism (the right objectivism) without transcendentalism (the wrong objectivism),
  • criticism (the right skepticism) without cynicism (the wrong skepticism),
  • liberalism (the right fideism) without dogmatism (the wrong fideism), and
  • phenomenalism (the right subjectivism) without relativism (the wrong subjectivism).

Over the next four essays, I will elaborate further on the implications of my core principles of universalism, criticism, liberalism, and phenomenalism, as they relate to various broad approaches to philosophy:

  • In the essay Against Relativism, I will illustrate how my position against unanswerable questions rules out the possibility of solipsism and egotism, as well as particular kinds of idealism about both reality and morality.
  • In the essay Against Dogmatism, I will illustrate how my position against unquestionable answers rules out the possibility of both appeals to authority and appeals to popularity.
  • In the essay Against Cynicism, I will illustrate how my position against relativism in turn rules out the possibility of justificationism about either reality or morality, as well as the reduction of prescription to description (scientism) and the reduction of description to prescription (constructivism).
  • And in the essay Against Transcendentalism, I will illustrate how my position against dogmatism in turn rules out the possibility of supernaturalism and the moral analogue thereof that I term supernurturalism, as well as particular kinds of materialism about both reality and morality.
