Stoicism, Substance Dualism, and the Irreducibility of the Rational Faculty

Two posts by Grant C. Sterling to the International Stoic Forum. First: January 20, 2012, “A Brief Reply, Re: Dualism,” in reply to Malcolm. Second: February 28, 2013, “Stoic Dualism and ‘Nature,’” in reply to TheophileEscargot. Preserved by Dave Kelly, 2026. Layer: Theoretical Core — Philosophical Commitments. Attribution: Sterling.

Editorial Note — Dave Kelly

These two messages together constitute Sterling’s most direct primary-source statement of substance dualism as a philosophical commitment, and they are notable for what they are not: neither message argues for dualism by appeal to ancient Stoic physics or Stoic cosmology. The January 2012 message is explicit that Sterling’s dualism is “not developed in opposition to the ancient Stoic metaphysics, but to modern scientific physics” — the argument is that no physicalist account, ancient or modern, has ever explained how particles undergoing electro-chemical processes could have the qualitative character of pain or the conceptual content of a valid logical inference. The certainty of qualitative mental experience is offered as more secure than any other proposition Sterling holds. The February 2013 message extends the argument from mind in general to moral knowledge specifically: if no domain of inquiry uses a single method, and if mathematical and logical truths are not best answered by empirical observation, then morality — which Sterling holds can never be empirical — requires the same non-physical rational faculty that grasps logical necessity. The sandwich examples work through competing natural inclinations (self-preservation against social cooperation) to show that a physicalist “nature-studied-scientifically” cannot adjudicate what one is actually obligated to do; only a rational faculty capable of intuiting the wrongness of taking what belongs to another can. Read together, the two messages ground C1 in the same epistemic structure that grounds C3 (Ethical Intuitionism) and C5 (Correspondence Theory): a physical account of mind cannot house a truth-tracking faculty, and without such a faculty neither mathematical nor moral knowledge is possible.

Message One: A Brief Reply, Re: Dualism

Grant C. Sterling to the International Stoic Forum, January 20, 2012. Replying to Malcolm on whether the ancient Stoic account of the mind as a “state of matter” is compatible with modern physicalism.

Malcolm:

In brief, my position is like this:

1) I am absolutely certain, beyond any possibility of error, that I have qualitative mental experiences. I am more certain of this than any other proposition.

2) Experience consistently tells me that I make choices on the basis of the qualitative content of these experiences. For example, I engage in complex reasoning (I may read a philosophical proof, which I find convincing because I recognize it as having a certain logical form which I have previously analyzed and found to be deductively valid), and on the basis of this reasoning I may come to believe a proposition which leads me to act in certain ways. (As an example, I have turned down an opportunity to eat veal, which I find to be extremely delicious, on the basis of arguments designed to show that the way in which the veal is raised is morally repugnant. Or, I have consciously chosen to think about outcomes in a different way as a result of long discussions about Stoic theory of personal identity and harm.)

3) Science tells us that when we are having mental experiences our central nervous system is undergoing various sorts of electro-chemical processes.

My dualism is not developed in opposition to the ancient Stoic metaphysics, but to modern scientific physics.

You say that for the ancient Stoics, the human mind is a “state of matter”. The problem that I was bringing up is that there is no room in modern Physics for any such notion. Modern Physics recognizes only physical matter in the brain, consisting of various particles undergoing various electro-chemical processes. None of those particles or processes are understood as having characteristics like “the feeling of pain” or “the concept of modus ponens”, etc.

So, today, in 2012, if you say that “the mind is a state of matter” then you must either explain how it is that various brain particles can have such properties, or claim that there exist forms of “matter” that are utterly unlike any that physicists have discovered. I see no hope in accomplishing either of those goals. Hence, I see no way that a philosopher today can claim that the mind is a form of matter. (I am no idiot — I know full well that many, perhaps most, philosophers hold such a view. I am asserting that they have never explained how this is possible.)

Message Two: Stoic Dualism and “Nature”

Grant C. Sterling to the International Stoic Forum, February 28, 2013. Replying to TheophileEscargot on whether dualism fractures the unity of Stoic thought and disables its ability to guide action.

On 2/26/2013, TheophileEscargot wrote: “This dualism however creates some differences from ancient Stoicism. First, the appealing unity of Stoic thought, where a single system applies to all domains, is lost.”

The ancient Stoic system already allowed for the ‘sayables’, which are not corporeal.

More seriously, I think it is obvious that no single way of investigating a problem applies to all domains. Despite frantic efforts, no-one has convinced me that mathematical (or logical) questions are best answered by empirical observation. And I think Sam Harris’ work contains a clear and obvious error right at the beginning — science cannot tell us what life is “better” than another life, and even if it could it cannot tell us why we have a genuine obligation to pursue ends that are not important to us. But that’s a very long story, which I won’t explore right now — suffice it to say that I don’t think morality is or can ever be empirical. And since I don’t see how science can ever claim to evaluate the subjective content of people’s minds, I don’t think real psychology is empirical, either. (The discipline called “psychology” pretends to be a science, but psychologists blatantly cheat by accepting the introspective reports people give of their mental states as data, while then claiming not to be following an introspective — and hence non-empirical and non-physicalist — discipline.)

But if we define “Nature” as “the realm of all things that exist”, then of course all of us dualists are just as much ‘naturalists’ as anyone, and just as committed to a ‘unity of all knowledge’. Indeed, I would have much preferred it if the word ‘science’ still had its original meaning (any type of knowledge) rather than its modern meaning (a strictly empirical investigation). I would be happy to say that I study “moral science”, if that word had not been corrupted.

TheophileEscargot continued: “Second, it becomes more difficult to apply decision criteria to what is virtuous, since nature-studied-scientifically cannot be used for guidance. E.g. suppose I miss breakfast, and at work I see a tasty-looking sandwich someone has stored in the fridge, which I could eat without being identified as the culprit. Is it moral for me to eat the sandwich? The ancient Stoics would say no, it is immoral, because the nature of human beings is cooperative and social, and it goes against that nature to eat a sandwich reserved for someone else. What criteria does a dualistic modern Stoic use to decide whether to eat the sandwich?”

But is it not also my nature to seek self-preservation? So why isn’t it ‘natural’ for me to eat nourishing food when I’m hungry?

Suppose we change the case — suppose that it is my sandwich sitting on the table in front of me, but some other person grabs it to eat it himself. Now is it moral for me to take the sandwich back from the other person?

Or suppose that you and I are in a plane that crashes on a (previously) deserted island, and we’re the only survivors. We both see a sandwich, which belonged to one of the now-deceased passengers. Who gets it? It’s in my nature to seek self-preservation, but also in my nature to be socially cooperative. It’s in your nature to seek self-preservation, but also to be socially cooperative. What should I do?

Or take a radically different case — I am a judge, you are on trial. There is overwhelming proof of your guilt, and you have been convicted. The law says that the penalty is 10–20 years in prison. Do I uphold my social nature by enforcing the law of society, or uphold my social nature by acting altruistically towards you and setting you free, or uphold my goal of self-preservation by asking you for a bribe to set you free?

This is why I hate it when people (often empiricist-physicalists, but often not) equate “morality” with “altruism”. Even if the two concepts often coincide, they by no means always coincide. That an action was “altruistic” can (with proper finagling of definitions) be observed. That the altruistic action is truly virtuous or appropriate cannot.

So unless we accept that we have some sort of ability to intuit the truth of certain fundamental propositions (in logic, mathematics, ethics, theory of knowledge, etc.), we cannot get anywhere in any subject. Few empiricists have actually acknowledged the paucity of information we receive from the senses. Even fewer physicalists have attempted to explain how the idea of “understanding”, “thinking” etc. make sense in the realm of a theory which allows only for mass, charge, etc.

So, as a dualist, I think that we can know that it is wrong to take that which belongs to another, and we can know that in the original circumstances my desire for tasty food is insufficient reason to overturn the prima facie wrongness of stealing. I would happily say that it violates my nature as a rational being to act in this way — I just see no reason to think that my nature as a rational being is a physical thing, known by means of the five senses.

Regards, Grant, unabashed Stoic dualist

Corpus Note — Dave Kelly

These two messages together establish the primary-source ground for Sterling’s substance dualism, and they establish it on epistemic rather than cosmological grounds.

First, from the 2012 message: qualitative mental experience is the proposition Sterling holds with more certainty than any other. No physicalist account, including modern physics, has explained how particles undergoing electro-chemical processes could possess the felt character of pain or the conceptual content of a valid logical inference. The dualism is directed against contemporary physicalism, not against ancient Stoic materialism — Sterling explicitly declines to found his position on a defense of ancient Stoic physics.

Second, from the same message: the burden of proof runs against the physicalist, not the dualist. Anyone claiming the mind is a state of matter must either explain how brain particles acquire qualitative and conceptual properties, or posit an unknown form of matter unlike any physics has discovered. Sterling holds that neither has been accomplished.

Third, from the 2013 message: no single method of investigation applies to every domain. Mathematical and logical truths are not best known by empirical observation; morality, on Sterling’s account, can never be empirical; and the subjective content of minds cannot be evaluated by a science that only pretends to non-introspective method while secretly relying on introspective reports as data. This is the direct link between C1 and C3: if the rational faculty that grasps logical necessity is not physical, and if moral knowledge requires the same kind of non-empirical grasp, then moral knowledge requires a non-physical faculty.

Fourth, from the same message: the sandwich examples demonstrate that appeals to a physicalist “nature-studied-scientifically” cannot resolve genuine moral questions, because natural inclinations toward self-preservation and social cooperation can conflict, and no empirical fact about which inclination is stronger settles which action is right. Only a rational faculty capable of intuiting the wrongness of taking what belongs to another — a faculty Sterling holds is not a physical thing known by the five senses — can adjudicate the case.

Stoicism, Correspondence Theory of Truth, and Objective Moral Facts

Two posts by Grant C. Sterling.

Editorial Note — Dave Kelly

These two messages together constitute Sterling’s most direct statement of the correspondence theory of truth as the only defensible criterion and his argument that Stoicism cannot stand without it. The August 2015 message establishes the core claim: correspondence with reality is the only criterion of truth; the Stoics were pure realists in this regard; and the entire revisionary project of Stoicism — the claim that value impressions are false — depends on there being objective facts for impressions to correspond to or fail to correspond to. Remove the correspondence criterion and there is no basis for calling value impressions false rather than merely culturally contingent or personally inconvenient. The January 2022 message adds the epistemological clarification that Scruton’s objection to correspondence theory fails because it demands a definition of “fact” when “fact” is already the fundamental ontological category — at some point something must be accepted as foundational. This is where correspondence theory and foundationalism meet: both require that some categories be accepted as primitive rather than defined in terms of something more fundamental.

Message One: Correspondence Is the Only Criterion of Truth

Grant C. Sterling to the Stoics Yahoo Group, August 20, 2015. Thread: “Re: Regarding Criterion of Truth / Cognitive Impressions.” Responding to a challenge to the objectivity of the criterion of truth and the concept of cognitive impressions.

A) I am, in this thing like almost all others, a philosophical dinosaur.

The only “criterion of truth” that I recognize is correspondence with the facts — correspondence with reality. I reject utterly any notion of “truth” wherein something can be “true” and yet not match reality. And I am an authentic Stoic in this regard — the Stoics were pure realists in this regard.

You say that you are not prepared to accept the idea of an objective “what is”. But this threatens the very basis of Stoicism. Because the foundation of Stoicism is the notion that things that are not in our control are neither good nor evil — that Virtue is the only good and Vice the only evil. These are taken to be objective facts.

Pain and death and defeat and unemployment and rejection (etc.) all seem to be bad things. “Common sense” says they are bad things. Our pre-existing notions say that they are bad things. Stoicism says that nevertheless they are not — all these impressions are false, and we must radically revise the way we see the world to embrace the truth. If we undermine the claim that there are objective facts, it is hard to see what justifies us in radically revising our beliefs.

B) The Stoics do not hold that the Cognitive Impression is the criterion of truth — they hold that it is the basis of knowledge. Those are utterly different, although related, ideas.

Consider: “The number of molecules of O(2) in this Pepsi can is even” and “The number of molecules is odd.” Either the first or the second is true, and the other is false. It is absolutely impossible for any human being to know which is which. Having a cataleptic impression guarantees truth, because a cataleptic impression by definition always corresponds to the facts. But billions of sentences are true for which no one has a cataleptic impression.

C) For a sentence to be known to be true, one must have a clear understanding of the terms in the sentence. So in order to know the truth of “I see a chair,” you must have a clear understanding of chairs. An impression held by someone who lacks that clear understanding cannot be cataleptic with respect to that category — but this does not undermine the existence of cataleptic impressions as such. Many things we believe are things that we cannot or do not know, because we do not have a cataleptic impression of them. I believe that Barack Obama is President of the U.S., but I do not have a cataleptic impression that this is true, so I do not “know” it. I nevertheless believe that it is objectively true — I assent to the (non-cataleptic) impression that it is the case.

Regards, Grant

Message Two: Correspondence Theory and the Fundamental Ontological Category

Grant C. Sterling to the International Stoic Forum, January 10, 2022. Thread: “Re: What is Truth?” Responding to the claim, based on Scruton, that trying to decide what is true is futile because the concept of fact cannot itself be defined.

In order to define some term informatively, there need to be other, more fundamental notions that you can appeal to.

Scruton’s fallacy is his failure to see that at some point this process must stop. He has answered the question “What is Truth?” completely — truth is correspondence of a statement with the facts. Then he demands a definition of “fact”, and is frustrated that none is forthcoming. But that is because he demands too much — he has made “facts” into the fundamental ontological notion, and is then frustrated when he finds that he cannot define it in terms of more fundamental notions. But that is not because “truth” cannot be defined — it is because he cannot see that at some point something must be accepted as fundamental.

(The Stoics never used the cataleptic impression as a criterion of truth — they used it as a criterion of knowledge. That is very different. And interpretations of Stoicism exist that are immune to the standard objections, although some of the Stoics may not have seen the problems. But, again, this only connects to knowledge, not truth.)

Regards, GCS

Corpus Note — Dave Kelly

These two messages together establish the three most important claims Sterling makes about correspondence theory as a philosophical commitment.

First, from the 2015 message: correspondence with reality is the only criterion of truth, and this is the authentic Stoic position. The Stoics were pure realists. Any theory of truth that permits something to be true without matching reality is rejected without qualification. This is Sterling’s foundational epistemological stance, and it is not tentative or hedged.

Second, from the 2015 message: the entire revisionary project of Stoicism depends on correspondence theory. The claim that value impressions are false — that pain, death, defeat, and rejection are not genuine evils despite appearing to be so — requires that there be objective facts for impressions to correspond to or fail to correspond to. If there are no objective facts, Stoicism cannot call these impressions false. It can only say they are inconvenient, or culturally contingent, or personally unhelpful. The normative force of the Stoic revision is entirely carried by the claim that the impressions are factually wrong, not merely psychologically uncomfortable. Remove correspondence theory and that claim has no ground.

Third, from the 2022 message: the demand that “fact” itself be defined is a regress demand that misunderstands foundational categories. Correspondence theory defines truth in terms of facts. Facts are the fundamental ontological category. At some point something must be accepted as fundamental and not further defined. This is the junction between correspondence theory and foundationalism: both commitments require accepting certain categories as primitive rather than derived. The objector who demands a definition of “fact” is making the same error as the objector who demands a justification for Theorem 10 from something more fundamental — both fail to see that foundational categories terminate the regress rather than extending it.

Stoicism, Foundationalism, and the Structure of Ethical Knowledge

Two posts by Grant C. Sterling.

Editorial Note — Dave Kelly

These two messages constitute Sterling’s most direct treatment of the foundationalist structure of ethical knowledge and the independence of foundational ethical propositions from both theology and empirical observation. The January 2015 message sets out Sterling’s taxonomy of knowledge sources and identifies self-evident necessary truths — known through rational perception rather than sensory input — as the correct account of how foundational moral propositions are known. This is the epistemological ground of the foundationalism commitment: Theorem 10 is a self-evident necessary truth apprehended through rational perception, not derived from prior premises and not imported from theology or experience. The June 2017 message establishes the independence of foundational ethical beliefs from theological beliefs through the distinction between beliefs that merely connect and beliefs that logically support one another. Stoic ethics and Stoic theology are connected — each makes the other more coherent as a whole — but neither is the logical ground of the other. Refute the theology and the ethics stands. Dissolve the ethics and the theology stands. This is the structural claim that makes Sterling’s reconstruction philosophically defensible: the six commitments do not rest on cosmological or theological foundations that have collapsed. They stand independently.

Message One: Two Types of Moral Premises — The Structure of Ethical Knowledge

Grant C. Sterling to the Stoics Yahoo Group, January 19, 2015. Thread: “Re: Two (Types of) Moral Premises.” Responding to Steve Marquis on the sources of moral knowledge.

By “moral” I meant the properties of goodness, badness (evil), virtue, vice, preferred, dispreferred, right, or wrong. None of those properties can be sensed. Some of these properties may not be fundamental — i.e., some may be defined in terms of others. I was not concerned with this distinction in that post. Any value content in one of my impressions cannot have come directly from the five senses.

The world is a certain way. We receive basic concepts from the world. (Or perhaps some are innate.) Then we make up arbitrary systems of noises, and squiggly marks, to refer to those concepts. So the words are totally arbitrary and conventional. But the basic concepts they refer to cannot be totally arbitrary, or else you would use a word and I would stare at you blankly. And the nature of reality is not arbitrary or conventional. Of course, we can also make up complex concepts based on the simpler concepts we perceive. But all words that we invent to refer to complex properties are meaningful only insofar as they are composed of simpler properties we are aware of.

If our words do not refer to anything that exists in reality, then no-one’s definitions are right. If our words do refer to things that exist in reality, then: (a) if the property is simple, the word has no definition — you cannot define, for example, the experience of yellow; all we do is conventionally agree which noise will correspond to which property; (b) if the property is complex, then whoever’s definition matches reality best is objectively right. The arbitrariness of language in no way makes truth arbitrary.

There are (at least) four sources of knowledge:

(a) Sensory experience — experiences in the mind which we take to be caused by our five physical senses.

(b) Extra-sensory experience — mystical experience, religious experience, divine revelation, pronouncements of the moral sense, clairvoyance. What all of these share is the idea that we can detect contingent truths about the external world. Since these are contingent truths, our knowledge of them will vary. If you have learned the truth of proposition ‘p’ by clairvoyance, then I cannot know that ‘p’ is true unless I also have the same clairvoyant experience. What one person has learned this way, another need not know.

(c) Rational perception of self-evidence — this is different from all the others. A self-evident truth can only be evident through itself, and so only a necessary truth can be self-evident. Knowing a truth because it is self-evident is not the same thing as learning a truth by experience, even mystical, religious, or extra-sensory experience. In the case of (a) and (b) we learn the truth because we receive some new input. In the case of (d) we received the input at birth. In the case of (c), we gain a new understanding without having new information inputted to us.

(d) Purely innate knowledge — some people think that we are simply born knowing certain truths, or at least born with them somehow contained inside us so that we only need to think in the right way to become aware of them. In principle, innate knowledge could vary — I could know things innately that you do not.

(c) is the key category. It is different from (b) because a self-evident truth is not learned through any experience, even a non-physical one. It is different from (d) because it cannot vary between persons — a self-evident necessary truth is self-evident to any rational faculty that attends to it. What is self-evident does not depend on what inputs you have received.

I think the fundamental truths of ethics are necessary, self-evident truths. Jesus was not needed to tell us the fundamental truths of Stoicism. They are necessary, self-evident truths that any rational faculty can apprehend directly.

On the is-ought problem: you can run through all the descriptive observations you want. Here is data about the psychological consequences of rape for the victim. There is data about which societies have disapproved of rape under which circumstances. Go on making all the observations you want to make. But somewhere down the line you have to start making assertions like “it is wrong to harm other people just to get pleasure for yourself” or “pain is a dispreferred indifferent, and ceteris paribus one ought not to perform actions directed towards producing dispreferred indifferents” or something like that. At some point you have to bridge the is/ought gap. And you will not bridge it with any statement about what you can see, hear, taste, touch, or smell. You can add up a million Premise 1s, but until you put in a non-sensory moral Premise 2, you will never get to a conclusion.

MORAL PROPERTIES CANNOT BE SENSED. That is the fulcrum.

Regards, Grant

Message Two: Support versus Connection — The Independence of Foundational Ethical Propositions

Grant C. Sterling to the Stoics Yahoo Group, June 5, 2017. Thread: “Re: Basic Stoic Ethical Principles.” Responding to questions about whether Stoic ethics requires Stoic theology.

There are (at least) two ways that philosophical principles can be related to one another — I will call them “support” and “connection”. They are very different things and should not be confused, as they often are.

Suppose that I discover that my wife is having an affair. I discover multiple occasions when she is not where she says she is going to be. I find a partially written love letter hidden in her belongings. So I come to believe that she is having an affair. Now suppose that a good female friend of mine confides that her husband Bubba is having an affair. She cites similar evidence. So I come to believe this as well. Then one day it occurs to me that my wife is good friends with this woman’s husband. After a while, I come to believe that my wife is having an affair with my friend’s husband.

Notice that neither of these two beliefs relies on the other in any logical sense. I came to have the two beliefs separately, based on entirely independent sets of evidence. We can imagine a sufficient amount of evidence to say that I would be fully justified in believing either of them without the other. We could imagine my discovering one day that my wife’s lover could not possibly be my friend’s husband, and this would not in the slightest change my belief that each of them was having an affair. At the same time, if the evidence in the two cases matches up very well, I have a fuller and better understanding of the universe by combining them.

On the other hand, imagine a very different situation. Suppose I come to believe that my wife is a reptilian space alien in disguise. Upon contemplating this further, I see that I must accept that reptilian space aliens exist, that they have studied humans for some time, that some sort of effective space travel must exist for them. These beliefs are not independent of my original belief — were I to discover that I was wrong about my wife’s alienhood I would immediately abandon all these other beliefs.

In the infidelity example, the beliefs were connected. Each makes perfect sense on its own. Each was discovered independently and independently supported by evidence. Yet they are related in a way that allows them to be combined into a coherent whole. In the alien example, the new beliefs are supporting beliefs — a foundation for the belief that she is an alien. If the foundation falls, everything built on it falls with it.

My contention is that the ethical beliefs of the ancient Stoics are related to their theological beliefs in the former way, and not the latter way. They believed certain things about ethics. They believed certain things about the gods. They then connected them together. But they did not hold their beliefs about ethics because of their theology, nor did they hold their theology because of their ethics. If you had somehow convinced Zeno that fiery pneuma was not in fact a material substance or that there was no conscious mind at the heart of the universe, I do not think that he would have abandoned his belief that virtue was good. There is no obvious logical connection between these ideas. Refute Stoic ethics and you will not have made the slightest dent in panentheism or materialism. Dissolve panentheism or materialism and you will not have refuted Stoic ethics. You will of course destroy the particular connections the ancient Stoics drew — just as if Bubba is not having an affair I will delete my belief that my wife is having an affair with Bubba — but you will not refute the connected doctrine.

Connecting beliefs can strengthen both, as in my example. If there is Reason at the heart of the universe, that can enhance the idea that Reason is vital to human life. If the perfect gods control all externals, that makes it easier for me to stop thinking that any external can be evil. But there is no reason why an atheist cannot articulate the same Stoic ethical principles that a monotheist affirms. And that is precisely what I do myself. I am a theist for reasons that have nothing to do with ethics. I am a Stoic for reasons that have nothing to do with theism. But of course I connect those two views. If you convinced me tomorrow that monotheism was false, I would not take that as evidence that my ethics or my epistemology were false.

I reject the call for grounding of ethical beliefs in theology. Ethics cannot be grounded in the will of God. The Euthyphro problem shows that — divine ethics ends up becoming either arbitrary (God, for no good reason, randomly assigns “good” to kindness and “bad” to cruelty — it would have been just as legitimate had he randomly picked the opposite), or else it ceases to be divine (God applauds kindness because it is good, which means that its goodness is antecedent logically to God’s approval). Furthermore, I have never met anyone who adopted basic ethical principles because of their theology. I have never met anyone who started disapproving of cheaters, liars, rapists, and thieves because he deduced the wrongness of those actions from his theology. There is no logical connection that I have ever seen — “it is wrong, ceteris paribus, to break a promise” seems to require only that I understand what promises are and how they work, not that I understand anything about God.

So I do not ground my ethics in my theology, and I do not see any need for me to do so.

The Stoics think that we already know (basically) what Virtue is, and we already know that it is good. What we need to do is start working at eliminating the desires that obscure our vision of the true good. Telling people to be good Boy Scouts misses the point. They already know that they ought to be doing those things, but their desires lead them astray. So you cannot get someone started on the road to eudaimonia without directly confronting them with the truth that externals are neither good nor evil.

Corpus Note — Dave Kelly

These two messages together constitute the primary source material for Sterling’s foundationalist commitment. The January 2015 message establishes the epistemological taxonomy: self-evident necessary truths, known through rational perception (category c), are the foundational moral propositions. They are not learned from experience, not received through any input, and not variable between rational persons. Moral properties cannot be sensed; therefore moral foundations require non-sensory rational access. This is the precise epistemological claim that foundationalism makes in Sterling’s framework: Theorem 10 is a self-evident necessary truth, and the examination of impressions against it is an exercise of rational perception of self-evidence, not empirical inference.

The June 2017 message provides the structural claim: ethical beliefs and theological beliefs are connected, not mutually supporting. The six commitments — including the foundational value claim that virtue is the only genuine good — do not rest on ancient Stoic theology, cosmology, or physics. They stand independently. Dissolving ancient Stoic physics, as Inwood correctly observes is necessary, does not touch the foundational ethical propositions. Those propositions were not grounded in the physics. They were merely connected to it. The connections are severed by the reconstruction; the propositions remain.

The thread opens as a dispute over the word “fact” itself, provoked by Gich’s objection that defining moral facts in terms of facts is circular. Sterling’s two February 24 messages answer that objection by building the apparatus from the ground up: first the correspondence theory of truth (belief on one side, fact on the other, truth as the relation between them), then a four-part epistemology distinguishing contingent from necessary facts and fallible from infallible means of knowing them. The second message ends by promising to apply the apparatus to moral belief specifically — a promise redeemed three weeks later in the March 13 message, in reply to Steve Marquis’s attempt to derive Stoic value claims from an empirically-grounded starting assumption. Sterling’s reply is the source of the corpus’s clearest statement of the intuitionism-or-nihilism dichotomy and the sensory-exclusion argument: moral terms cannot be heard, smelt, tasted, seen, or felt, so any access to moral facts must be non-empirical. The three messages should be read as one continuous argument, interrupted by three weeks of thread traffic: truth is correspondence → necessary truths are known by direct rational apprehension → moral truths, being necessary and non-empirical, are known the same way, and there is no stable alternative to this position short of nihilism.

Message One: Truth Is Correspondence, Facts Are Not in the Mind

Grant C. Sterling to the International Stoic Forum, February 24, 2020, 16:41 UTC. Thread: “What is a fact?” Responding to an extended exchange with Gich and Steve Marquis over whether “moral facts” is a coherent phrase.

OK, I have been busy, and I was hoping that this thread had run its course. But I see now that I should have made time to send this message sooner. (By the way, I am using ‘the universe’ to mean ‘all of reality’, ‘Being’, ‘everything that really is’, etc. If you believe in multiple universes, they are all still part of ‘the universe’ as I am using the phrase.)

Let’s start with a (relatively!) simple case. I believe that it is raining outside. That belief is internal to me. It has content, it is ‘about’ something — namely, rain outside. But some beliefs are false — sometimes I believe that it is raining outside, but it isn’t. So beliefs are about the world, and when they match the way the world really is, they’re true; when they don’t, they’re false. “Truth” is correspondence of a belief with reality — that’s the ‘correspondence theory of truth’, and it’s the theory of truth that would have been embraced by the ancient Stoics if anyone had asked them, which they didn't, because basically 100% of people throughout most of human history have not only embraced it but thought it was so obvious that there wasn't even a name for it.

So we have something on the side of the mind — let’s stick with “belief” for a moment. We have something on the side of the universe. And we have the correspondence between them, which is “truth”. Now we need a name for ‘the way the universe actually is’. And the word that philosophers have pretty much unanimously chosen is “fact”. So “facts”, as philosophers use the word, are not things in our minds — they’re things in the world.

Belief (in the mind) → Fact (how the universe is) = Truth. Belief that fails to match Fact = Falsehood.

You can argue among yourselves about whether or not “fact” was a good choice for the word for the way the universe is. We certainly need some word. It’s not a clear deviation from common usage — for example, we commonly say “in fact” when we’re about to make a claim about how the universe actually is, often in contradiction to how someone has claimed that it was. But I won’t spend time arguing about that. “Fact” is the word philosophers have chosen, and seeing no better word I’ll use the word that way as well.

Now the story above works with other mental attitudes as well. For example, I perceive that there is a Pepsi can on the desk in front of me. If, in fact, there is a Pepsi can in front of me, then my perception is accurate. (You can call this match “truth” as well, if you like — it’s certainly a close cousin to ‘truth’ as applied to beliefs.) But the perception is still in the mind, and the facts about what I am perceiving are still in reality, outside the mind. Or, in a different case, we say “her wish came true” when her wish, in her mind, matched up with the facts of the universe. I can desire something, and I will receive positive feelings when the world in fact fits my desire, and negative feelings when it doesn’t (which is why I need to change my desires in the way the Stoics recommend). There are many sorts of mental attitudes that are ‘about’ the universe, and sometimes the universe fits those attitudes, and sometimes it doesn’t.

So cataleptic impressions, if they exist, are not the same thing as ‘facts’. An impression is a way of seeing the world — but some impressions are false, they don’t match up with the way the universe really is. That’s the heart and soul of Stoicism — most of our impressions about good and evil do not match up with the way good and evil really are in the universe. Cataleptic impressions are a special class of impressions, because they always match up with the facts. But CIs are still inside our minds, and if there were no facts outside the mind, our CIs could never be true — that is, they could never be cataleptic! So CIs in my mind need facts outside my mind in order for them to be true.

So Stoicism is incoherent without moral facts. Unless the universe really contains good and evil, right and wrong, virtue and vice, and contains them in definite states that are independent of how we want them to be, the whole view would make no sense. Externals are neither good nor evil — the Stoics think this is a fact about the universe. If there are no facts, then the Stoic view of what is good, evil, or indifferent is no more valid than the ordinary view. The Stoics think that we have role-duties. This is a (putative) fact. If there are no such facts, then we have no duties, and psychopaths are closer to the truth about morality than we are. Courage, the Stoics think, is a Virtue. If there are no moral facts, then there are no virtues. The Stoics consistently believe that there are objective “right answers” about these things, and their view requires this.

As I said before, if you have an irrational fixation against the word “fact” that matches Gich’s irrational fixation against “moral”, by all means use some other word or phrase. But make sure not to pick a word or phrase that ordinarily refers to something on the left side of the truth-correspondence arrow. Don’t use ‘impression’ (cataleptic or otherwise), ‘belief’, ‘opinion’, or even ‘truth’. Some philosophers like ‘state of affairs’. Whatever. But I hope that I am sufficiently clear now: mental attitudes point out towards the universe. Sometimes they match up with the way the universe actually is. (Sometimes, they don’t.) I am using, always have used, and intend to continue to use the word “fact” to refer to the way the universe actually is.

This is quite long enough for now. I’ll have another post about things like “knowledge” and “certainty” and “skepticism” and “pragmatism” at a future time.

Message Two: Necessary Facts, Known with Certainty

Grant C. Sterling to the International Stoic Forum, February 24, 2020, 21:57 UTC. Same thread, same day, continuing the epistemology.

So, again, however anyone else wishes to use their words, I will always mean by “fact” the objective reality, the state of the universe (essentially, what Steve and Kant call “noumena/-on”).

Let us return to where I started, with a belief. I believe that it is raining outside. If that belief corresponds to the facts, if it actually is raining outside, then the belief is true.

But let’s for a moment stop thinking about whether our beliefs correspond to the facts, and think about the beliefs themselves. Some beliefs are reasonable, rational, or justified, while some are not. My belief that it is raining outside is based on the fact that I heard today’s weather forecast and it predicted continual rain, plus the fact that I was outside a while ago and perceived rain, as well as solid dark clouds in every direction, suggesting that the rain would not be stopping soon. Those two things together give me good reason, I think, to believe that it is raining outside. Of course, I could easily imagine having stronger evidence. Evidence, ‘justification’, comes in degrees. Some of our beliefs are well justified, some poorly justified (and some clearly unjustified).

I am using ‘evidence’ in the widest possible sense. So, for example, suppose that I consider the proposition “modus ponens is deductively valid”. (M.p. is the argument structure: ‘If p, then q; p; therefore, q’. ‘Deductively valid’ means that it is impossible for the premises to both be true while the conclusion is false.) I can “see”, mentally, that m.p. is valid. That is, when I contemplate the propositions involved, it is obvious to my intellect that there is no way those premises could be true and the conclusion false, regardless of what you wish to plug in for ‘p’ and ‘q’. I would say that I have extremely strong evidence for the truth of that proposition, that my belief that it is true is overwhelmingly justified.

In fact, I would say that in this case I have certainty. Not just psychological certainty (“I’m really, really sure that it’s true”), although I do have that, but rational certainty — it is impossible (I assert) for this belief to be false.

When I use the word “knowledge” in the strict sense (that is, the careful, philosophical sense, not like ordinary conversation where people casually say “I know that…” promiscuously for a wide range of their beliefs), I will mean that I have rational certainty that my belief is true — it is impossible for me to be wrong.

This is the traditional sense of the word “knowledge”. It’s what Plato and Aristotle meant by the word, as well as most of their opponents. It’s what the Stoics mean. It’s not a popular view today among philosophers, because of course we know very little according to this definition. But I think that this is one area where ancient philosophers were wiser than contemporary philosophers. Anyway, wise or not, that’s how I’m going to use the word.

In fact, people like Plato were so concerned to mark off the difference between knowledge and belief/opinion that they even refused to call what we know a “belief” at all. That is, where I characterized “knowledge” as a rationally certain belief, Plato insisted on using the word “belief” in such a way that it meant by definition “something that falls short of knowledge”. For him, if I “believe that p”, then by definition I do not “know that p”. Although I am in fundamental agreement with him about what knowledge is, I think it’s easier to use modern language, where ‘knowledge’ is one species of belief — namely, certain belief.

Now keep in mind that I think that beliefs can be rational, justified, without being known. I do not know that it is raining outside. (In fact, the longer I spend typing this message, the weaker my justification gets.) But I think that my belief is justified. (Note that justification comes in degrees, but knowledge does not — you either know, or you don’t.)

OK, what kinds of beliefs could be “known”, and what kinds cannot? Well, on my view, contingent facts are tremendously difficult, if not impossible, to “know”. Because if the fact is not logically necessary, then that almost always raises the possibility that it isn’t a fact at all. There is no logically necessary reason why it must be raining outside right now, and so I can certainly imagine the opposite state of affairs. Since from a logical point of view both states are possible, it becomes very difficult to try to claim that I know either one with certainty. I would have to have some infallible method of grasping these contingent facts, and that leads us to our next problem.

By the same token, it is impossible to have knowledge of something if the means of gathering evidence is fallible. So, for example, my senses work indirectly, through a long causal chain, and every link in the chain introduces the possibility of error. So while I think that I am strongly justified in believing that there is a Pepsi can on my desk right now, because I clearly see it right in front of me, I must admit the possibility (however slight) that my senses are misleading me, or that I am dreaming. So I do not know that there’s a Pepsi can in front of me.

So there are four combinations: 1) contingent facts discovered by fallible means; 2) contingent facts discovered by infallible means; 3) necessary facts discovered by fallible means; 4) necessary facts discovered by infallible means.

1) Some very, very large percentage of our beliefs are beliefs about contingent truths based on fallible evidence, and hence do not constitute knowledge. The majority of our beliefs are based on our senses, or on the testimony of other people. Both of those methods are fallible, and so no knowledge whatsoever can ever come from them. But that’s fine — we seldom have to have knowledge; justified beliefs are fine. And this is also the realm of Science. Science builds strongly justified beliefs by putting together the sensory evidence of different people, coordinating it, testing it, etc. This will never reach certainty; scientifically-based beliefs are always subject to possible error and therefore should always be held in such a way that they can be revised if necessary. But, again, that’s just fine — it would be idiotic to throw out Science just because it doesn’t reach absolute certainty, and it would be idiotic to do the same with my many ordinary sensory beliefs. When I’m done today I will walk to the parking lot where I remember having parked my car, and I will expect it to be there. Yes, maybe I dreamed it. And maybe it has been stolen, or annihilated by an alien ray gun, or whatever. But the small possibility of error does not mean that I should reject the belief.

2) Now there is one area, and on my view only one area, where we have infallible knowledge of contingent facts — and that is our introspective knowledge of the contents of our own minds. I cannot be certain that it is raining outside, but I can be certain that I believe that it is raining. (You can’t be certain, because I might be lying to you. But my knowledge is direct and unmediated.) I believe that I hit my knuckle in a door earlier today, but I am certain that I feel mild pain right now. Knowledge is only possible in this case because, as I said, my awareness of my own mental states is direct and unmediated — there are no causal steps that can go wrong in this case.

3) Fallible awareness of necessary facts commonly occurs in the case of believing things on the basis of testimony of others, even though one cannot “see” (directly grasp) the truth oneself. My Mathematician friends often tell me that certain things in higher Math have been proven, where I cannot grasp the proof. When I was a child, I believed that 6×0=0 because my teacher told me that it was true. This is not knowledge — the person speaking to you could be lying, or they could be mistaken, or you might be misunderstanding what they’re saying. Again, your belief-based-on-testimony might be justified, even very strongly justified. I think that I was very strongly justified in believing that 6×0=0 simply because my teacher and the Math textbook both agreed that it was true.

4) Finally, we come to infallible awareness of necessary facts. On my view, this comes when my mind directly and clearly grasps the fact which I claim to know. At some point, I saw that 6×0 had to equal 0. I apprehended its necessity, I grasped the fact directly with my mind. At some point in my life I knew that modus ponens was valid. I didn’t believe it because the book said that it was valid, or because I could plug in a few values for ‘p’ and ‘q’ and end up with conclusions that I was sure were true — at some point I grasped it directly with my Intellect. I cannot be wrong about this — it is rationally certain. I know it.

I’m out of time for today. I will apply all of this to moral beliefs tomorrow.

Message Three: Intuitionism or Nihilism — No Third Option

Grant C. Sterling to the International Stoic Forum, March 13, 2020. Same thread. Reply to Steve Marquis, who had proposed deriving Stoic value claims from the unstated assumption that existence is good, then reasoning empirically from there.

Steve: I owed you this response a long time ago. I will be as brief as I possibly can.

Marquis had written: “OK, your turn. Explain to me how I see (or smell, or whatever) the goodness of survival. Recall the teleological vs non-teleological explanations for the start of everything I gave as an example? … Common to all of those will be the unspoken assumption that existence is good and non-existence is not good. That is about as basic as I can possibly get. We can move to survival of species / individuals / eco systems / etc from that. … There is no smell test in particular but we can empirically (to the best of current science) have a well justified opinion about whether a thing is dead or not.”

I totally agree that IF one makes the unspoken ASSUMPTION that existence is good and non-existence is not good, you may then proceed by empirical (or quasi-empirical) steps to conclusions about ethics. But my entire point was that the assumption itself is non-empirical. One can assume that pleasure is better than pain, and reach conclusions about ethics from that. Or the assumption that Courage is better than cowardice, or that truth-telling is better than lying, or any number of other things. Give me a non-empirical assumption to use as a crowbar, and no door will stand against me.

But I deny you that assumption. Some ethicists try to cheat, and engage in a bit of linguistic sleight-of-hand. (I do not accuse you of this.) They say that they will use ‘good’ as an empirical term, meaning something like ‘in accord with evolutionary fitness’ or something like that. Then before you know it they’re telling you that you ought to do this or that. But of course that is deceitful. If you wish to distort the word ‘good’ in this way, I cannot stop you, but I can deny you the right to make the derivations that one can make with the word in its ordinary meaning. (I.e., from ‘this action would cause the most good’ many people accept ‘this action is right — I ought to do it’. But from ‘this action would cause the most evolutionary fitness’ we cannot immediately derive anything about what we ought to do.) Furthermore, they cheat — evolutionary fitness is a notion that applies to a particular entity. I am evolutionarily fit if I am well-suited to have my genes preserved in posterity. From this you might get conclusions about how I should best preserve my own life and health, or that of my close relatives, but you can never get to conclusions about sacrificing myself for people in distant countries, etc.

If, on the other hand, I grant you one non-empirical assumption, then how can you deny me the right to introduce a second assumption? Or a third? If intuition, or Reason, or whatever you wish to call it justifies your assumption that existence or life is better than non-existence or death, then I can argue that it justifies other things. So my claim that our alternatives are intuitionism on the one hand or nihilism (or total skepticism, which is identical for practical uses) on the other hand has nothing to do with certainty — either we can see into the moral realm (however dimly), or else we are blind. Prefer a fallible intuitionism aiming at contingent truths if you’d like, but I still don’t see any third alternative.

‘Good’, ‘bad’, ‘right’, ‘wrong’, ‘virtuous’, ‘vicious’ — none of these things can be heard, smelt, tasted, seen, or felt. If there are moral facts that we can know (or even have the most faintly justified beliefs about), then we have to have a non-empirical way of knowing them. Since I don’t believe in a moral sense, and since I think the truths are necessary and not contingent, and since I already believe in the power of Reason to give us (certain) knowledge of mathematical and logical truths… my ethical position falls out of that.

And, for what it’s worth, I don’t see any better way of understanding the position of the ancient Stoics, either. I acknowledge that this is a debatable point (maybe they did believe in a sixth, moral, sense).

And none of this has anything to do with the existence of moral facts.

Corpus Note — Dave Kelly

These three messages together establish the complete epistemological chain from correspondence truth to moral intuitionism.

First, from the two February 24 messages: truth is the correspondence of a belief (in the mind) with a fact (in the world). Facts are not mental contents; cataleptic impressions, being mental, require external facts to correspond to in order to count as cataleptic at all. This makes Stoicism as a system dependent on moral facts existing outside the mind — without them, the Stoic evaluation of externals as neither good nor evil has no more claim to validity than any competing view.

Second, from the same messages: knowledge in the strict, traditional sense requires rational certainty, which requires both necessity (the fact could not have been otherwise) and infallible means of apprehension. Sterling identifies only two sources that meet this bar: introspective awareness of one’s own mental states, and direct rational grasp of necessary truths such as the validity of modus ponens or that 6×0=0. This second category — direct, unmediated intellectual apprehension of a necessary truth — is the epistemic mechanism that the March 13 message goes on to apply to ethics.

Third, from the March 13 message: any attempt to derive ethical conclusions empirically must smuggle in at least one non-empirical starting assumption (Marquis’s “existence is good”), and once one such assumption is granted, there is no principled way to refuse a second or third. This is the argument from unstable privilege — empiricism cannot license exactly one axiom and no more.

Fourth, from the same message: the sensory-exclusion argument and the resulting dichotomy. Moral terms cannot be heard, smelt, tasted, seen, or felt, so moral knowledge, if it exists at all, must come through a non-empirical faculty. Given that Sterling denies a distinct moral sense and holds that moral truths are necessary rather than contingent, the same rational faculty that yields certain knowledge of mathematical and logical truths is the faculty that yields knowledge of moral truths. The resulting dichotomy is exhaustive on Sterling’s account: intuitionism (fallible or infallible) or nihilism, with no stable third position.

Stoic Dualism and “Nature”

Post by Grant C. Sterling. Originally posted to the International Stoic Forum, February 28, 2013

Stoic Dualism and “Nature”

On 2/26/2013, TheophileEscargot wrote:

This dualism however creates some differences from ancient Stoicism. First, the appealing unity of Stoic thought, where a single system applies to all domains, is lost.

The ancient Stoic system already allowed for the ‘sayables’, which are not corporeal.

More seriously, I think it is obvious that no single way of investigating a problem applies to all domains. Despite frantic efforts, no-one has convinced me that mathematical (or logical) questions are best answered by empirical observation. And I think Sam Harris’ work contains a clear and obvious error right at the beginning — science cannot tell us what life is “better” than another life, and even if it could it cannot tell us why we have a genuine obligation to pursue ends that are not important to us. But that’s a very long story, which I won’t explore right now — suffice it to say that I don’t think morality is or can ever be empirical. And since I don’t see how science can ever claim to evaluate the subjective content of people’s minds, I don’t think real psychology is empirical, either. [The discipline called “psychology” pretends to be a science, but psychologists blatantly cheat by accepting the introspective reports people give of their mental states as data, while then claiming not to be following an introspective — and hence non-empirical and non-physicalist — discipline.]

Second, it becomes more difficult to apply decision criteria to what is virtuous, since nature-studied-scientifically cannot be used for guidance. E.g. suppose I miss breakfast, and at work I see a tasty-looking sandwich someone has stored in the fridge, which I could eat without being identified as the culprit. Is it moral for me to eat the sandwich? The ancient Stoics would say no, it is immoral, because the nature of human beings is cooperative and social, and it goes against that nature to eat a sandwich reserved for someone else. What criteria does a dualistic modern Stoic use to decide whether to eat the sandwich?

But is it not also my nature to seek self-preservation? So why isn’t it ‘natural’ for me to eat nourishing food when I’m hungry?

Grant, unabashed Stoic dualist

A Brief Reply, Re: Dualism

Post by Grant C. Sterling. Originally posted to the International Stoic Forum, January 20, 2012.

A Brief Reply, Re: Dualism

Malcolm:

In brief, my position is like this:

1) I am absolutely certain, beyond any possibility of error, that I have qualitative mental experiences. I am more certain of this than any other proposition.

2) Experience consistently tells me that I make choices on the basis of the qualitative content of these experiences. For example, I engage in complex reasoning (I may read a philosophical proof, which I find convincing because I recognize it as having a certain logical form which I have previously analyzed and found to be deductively valid), and on the basis of this reasoning I may come to believe a proposition which leads me to act in certain ways. [As an example, I have turned down an opportunity to eat veal (which I find to be extremely delicious) on the basis of arguments designed to show that the way in which the veal is raised is morally repugnant. Or, I have consciously chosen to think about outcomes in a different way as a result of long discussions about Stoic theory of personal identity and harm.]

3) Science tells us that when we are having mental experiences our central nervous system is undergoing various sorts of electro-chemical processes.

My dualism is not developed in opposition to the ancient Stoic metaphysics, but to modern scientific physics.

So, today, in 2012, if you say that “the mind is a state of matter” then you must either explain how it is that various brain particles can have such properties, or claim that there exist forms of “matter” that are utterly unlike any that physicists have discovered. I see no hope in accomplishing either of those goals. Hence, I see no way that a philosopher today can claim that the mind is a form of matter. {I am no idiot — I know full well that many, perhaps most, philosophers hold such a view. I am asserting that they have never explained how this is possible.}

Stoic Dualism: The Unified Soul and the Collapse of the Tripartite Model

Two posts by Grant C. Sterling. Stoics Yahoo Group, October 25 and October 27, 2013. Thread: “Plato’s Tripartite Theory of Soul.” Responding to Richard and Jan Garrett (Western Kentucky University) on why the Stoics rejected Plato’s three-part soul. Preserved by Dave Kelly, 2026. Layer: Theoretical Core — Philosophical Commitments. Attribution: Sterling.

Editorial Note — Dave Kelly

This thread is a direct philosophical exchange between Sterling and Jan Garrett, the first moderator of the ISF Yahoo Group after founding owner Eric Weingart handed it over. Garrett represents the sociological-historical reading: the Stoics shifted from a tripartite soul to a unified prohairesis because Hellenistic political conditions made collective reform implausible, leaving moral improvement as an exclusively interior individual task. Sterling does not dispute this historical account but goes straight past it to the philosophical argument: the Stoics rejected the tripartite soul because they had a superior explanation of the phenomena Plato’s tripartition was designed to handle. The two messages together constitute Sterling’s most complete statement of why the unified soul is not merely a Stoic preference but a philosophical necessity — and why accepting the tripartite model generates a problem Plato himself never solved.

Message One: The Unified Soul and the Collapse of Control

Grant C. Sterling to the Stoics Yahoo Group, October 25, 2013. Responding to Richard’s questions about what caused Stoicism to reject the tripartite model and what advantage the unified soul provides.

The Stoics had no need for the three-part model of the soul, because they had the theory that desire and emotion arise from assenting to value propositions. I am my faculty of choice, and it is the very same faculty of choice that assents to the propositions that lead to desire, the propositions that lead to emotion, and the propositions affirmed by reason. So, for the Stoics, when I “desire something and am averse to it at the same time”, all that really means is that I have assented to contradictory propositions. While it is certainly irrational to assent to two contradictory propositions, there is absolutely no doubt that humans sometimes do so, especially when the propositions are tangentially contradictory and not directly contradictory. Few people affirm “It is Tuesday” and “It is not Tuesday” simultaneously, but they may well affirm “I should always obey the law” and “I should do whatever it takes to get that shiny toy for myself”, even when it may turn out that committing a crime is the only way to get the toy.

If you deny the unitary soul, virtually all of Stoic thought collapses upon itself. For example, if my desires and emotions are not the result of my judgments, then they are not in my control, and so whether or not I am happy and passion-free is no longer in my control. A divided soul means that the faculty of choice, which resolves conflicts within the soul, cannot be identified with Reason, which is a party to the conflict and not always the winning party, and the basic Stoic outlook on life is torn asunder.

In haste, GCS

Message Two: The Quadripartite Problem — Plato’s Unresolved Difficulty

Grant C. Sterling to the Stoics Yahoo Group, October 27, 2013. Responding to Richard’s suggestion that the faculty of reason might serve as arbiter over the appetitive soul, and his question about whether hunger constitutes a judgment.

Consider Plato’s original problem. Sometimes the soul faces a conflict between wanting to do something and seeing that one ought not do it. If nothing can be at odds with itself, then the soul must have multiple parts. Etc.

If we accept this argument, then what happens when I face this conflict and I choose to do the wrong thing? Clearly, “I” selected “desire” over “reason”, and so “I” am clearly not “reason” — otherwise “I” am choosing against myself, which the theory says is impossible (and which is highly dubious even if we reject the Platonic premise). So if we accept the tripartite soul, I think we must actually accept a quadripartite soul — there must be an additional choosing-self over and above the three elements of the soul. Plato never really solves this problem, although he stabs at it. Which means that I am not my reason, I am not one with the Logos, etc.

Hunger, as nothing more than a purely biological reaction, is not a “desire” on the Stoic view. The same goes for “being cold.” For the Stoics (and for me) such raw biological functions are assigned to the body, not to a separate “part” of the soul. So I completely agree with you that no judgment is involved in them — but all the more reason why they are external to “me” entirely. Such bare urges are not the things that Plato usually has in mind when he speaks of “desires”, either, so the difference between him and the Stoics is not merely verbal.

Regards, Grant

Corpus Note — Dave Kelly

These two messages establish two arguments that together constitute Sterling’s most complete philosophical case for the unified soul.

The first argument, from Message One, is the explanatory superiority argument. Plato posited three parts of the soul to account for the phenomenon of internal conflict: how can a person both want and not want the same thing? The Stoics dissolved this problem rather than solving it within its own framework. There is only one faculty — the rational faculty — and apparent internal conflict is simply the result of assenting to contradictory propositions. The phenomenon Plato needed multiple parts to explain is explained by the unified soul assenting inconsistently. More importantly: if desires and emotions are not results of the rational faculty’s own judgments, they are not in the agent’s control, and the entire Stoic promise — that the agent can guarantee his own happiness by judging correctly — collapses. The unified soul is not a philosophical preference. It is the structural requirement of the control dichotomy.

The second argument, from Message Two, is the quadripartite regress argument. This argument attacks the tripartite model from within its own premises. If reason, spirit, and appetite are three genuinely distinct parts capable of conflict, then when I choose the wrong thing — when desire wins over reason — there must be a “choosing-self” that adjudicated the conflict in desire’s favor. This fourth element is not reason (which lost), not spirit, not appetite. It is a prior agent standing over the three parts. But now the regress applies to the quadripartite soul: when it faces a conflict, what adjudicates? Plato never resolved this. The Stoics avoided it entirely by identifying the self completely with the rational faculty. The apparent conflict that requires tripartition is, on the Stoic account, the rational faculty contradicting itself — a single agent assenting to incompatible propositions, which is irrational but not ontologically impossible for a unified self.

Both arguments directly support Document 12 (A Brief Reply, Re: Dualism) and the seven dualism support files. The unified soul is substance dualism’s positive account of the self: not merely the claim that mind is not body, but the claim that the self just is the rational faculty, and that everything else — including bare biological urges like hunger and cold — belongs to the body and is therefore external to the self.

The Ultimate Context: Sterling’s Stoicism in the History of Classical Philosophy and Its Modern Replacements

The Ultimate Context

Sterling’s Stoicism in the History of Classical Philosophy and Its Modern Replacements

Theoretical foundations: Grant C. Sterling (Eastern Illinois University). Analysis and synthesis: Dave Kelly. Prose rendering: Claude (Anthropic). 2026.

I. The Claim

Every philosophical system has an immediate context and an ultimate one. The immediate context of Grant C. Sterling’s Stoicism is the Stoic tradition itself: Epictetus above all, the ancient school behind him, and the modern conversation — scholarly and practical — about what that school taught and whether it can still be lived. Most engagement with Sterling’s work naturally occurs at this level. His reconstruction of Epictetus’s ethical psychology, his account of assent and impression, his treatment of the indifferents, his formulation of the theorems of Core Stoicism — all of these present themselves first as contributions to an understanding of Stoicism.

But the immediate context is not the ultimate one. The ultimate context of Sterling’s Stoicism is the history of classical philosophy as a whole and the modern replacement of its governing presuppositions. This is not an external frame imposed on the system for rhetorical effect. It is the frame the system itself requires in order to be understood. Sterling’s Stoicism is not finally a position within an intramural Stoic conversation. It is a fully determinate instance of the classical philosophical structure, held intact, in an intellectual environment that has replaced that structure nearly everywhere else. To read it in the narrower frame is to misidentify what it is and what is at stake in it.

II. The Classical Structure

Classical Western philosophy, from Plato through the Stoics through the medieval and early modern thinkers, operated from a set of governing commitments that can be stated precisely. Sterling’s reconstruction identifies six. The rational agent is not reducible to body, brain, or social environment; the human being possesses a non-material rational faculty capable of genuine judgment (Substance Dualism). That faculty exercises genuine freedom in assent — it can accept, refuse, or suspend, and this freedom is real origination, not merely the absence of external constraint (Libertarian Free Will). Certain moral truths can be directly recognized by the trained rational faculty; moral knowledge is recognition, not construction (Ethical Intuitionism). Reasoning terminates in first principles; the structure of knowledge rests on foundations rather than dissolving into an endless web of mutual support (Foundationalism). A proposition is true because it corresponds to reality; reality, not consensus or usefulness, is the measure (Correspondence Theory of Truth). And moral truths are among the truths there are; moral facts are facts (Moral Realism).

Two features of this structure must be held together. First, the commitments are classical, not narrowly Stoic. They define the shared terrain on which Plato, Aristotle, Epictetus, Augustine, Aquinas, Descartes, and Kant, in whom the structure's first internal fracture is already visible, conducted their disagreements. What unites two millennia of otherwise sharply divided philosophical work is a single underlying orientation: reason is answerable to reality. Second, the commitments are structural, not decorative. They are not six independent theses that happen to be congenial to one another. They constitute the conditions under which certain assertions are meaningful at all: I can know what is true. I can recognize what is right. I am free in my judgment. I am responsible for my assent. My character can be corrected, and philosophy can guide that correction. Remove any of the six and one or more of these assertions loses its footing.

III. Stoicism’s Place Within the Structure

Within the classical terrain, the schools differed over what to build on the shared foundation. The Stoics’ distinction was the rigor and completeness with which they built. Where other classical systems left the relation between metaphysics, epistemology, and ethics loosely articulated, the Stoic system — as Sterling reconstructs it — derives a complete ethical psychology and a complete practical discipline from the foundations with something approaching deductive tightness. The theorems of Core Stoicism are not aphorisms. They are a chain: from the universality of the desire for happiness, through the analysis of desire as judgment, through the location of the sole genuine good in the correct use of the rational faculty, to the practical disciplines of assent and action.

This is why Sterling’s Stoicism serves as the recovery vehicle in the corpus rather than merely one classical option among several. The six commitments state what the classical structure is. Sterling’s Stoicism demonstrates what the structure yields when it is taken with full seriousness and worked out to completion — a system in which every practical instruction is traceable to a foundational recognition, and every foundational recognition bears practical weight. The classical structure supplies the criterion; the Stoic system supplies the demonstration that the criterion can be lived.

The relation runs in the other direction as well. The corpus has shown, in a dedicated demonstration, that the six commitment are not optional enrichments of Epictetus’s ethical psychology but its necessary conditions. The discipline of assent presupposes an agent distinct from his impressions who genuinely originates his response to them; the claim that some judgments are false presupposes a reality against which they are measured; the claim that assent to falsehood about value is the sole source of misery presupposes that value is a matter of fact. Strip any commitment away and the practice does not become more modest — it becomes unintelligible. This holds notwithstanding the ancient school's official corporealism: the dualism at issue is a reconstruction claim about what the ethical psychology requires, not a historical claim about Stoic physics — a case the corpus makes at length in [Substance Dualism in Sterling's Stoicism], with the primary-source record in [A Brief Reply, Re: Dualism], [Stoic Dualism and "Nature"], and [Stoic Dualism: The Unified Soul and the Collapse of the Tripartite Model]. Stoicism and the classical structure are therefore not related as species to genus only. Each, pressed hard enough, produces the other.

IV. The Replacement

The classical structure did not fall to refutation. Each of the six commitments has a modern replacement, and in no case did the replacement enter through a decisive argument against the original. Physicalism displaced Substance Dualism; determinism and compatibilism displaced Libertarian Free Will; constructivism, emotivism, and naturalism displaced Ethical Intuitionism; coherentism, pragmatism, and historicism displaced Foundationalism; pragmatic, deflationary, and consensus theories displaced Correspondence; relativism, subjectivism, and noncognitivism displaced Moral Realism. The replacements entered through philosophical fashion, methodological assumption, and the prestige of the natural sciences. The classical commitments did not lose arguments. They lost cultural authority.

The mechanism of the displacement is as important as its content. The replacements retained the inherited vocabulary while replacing what the vocabulary referred to. Truth remained, emptied of correspondence. Reason remained, emptied of foundations. Morality remained, emptied of real moral facts. Freedom remained, emptied of genuine origination. This is why the displacement was largely invisible while it occurred and remains largely invisible now: the words on the page did not change. A discipline can continue to speak of truth, responsibility, and knowledge for generations after it has ceased to mean by those words what the classical structure meant, and its practitioners will not, from inside, detect the substitution.

Nor did the displacement remain confined to philosophy departments. Because the six commitments are presuppositions rather than conclusions, their replacement propagated through every field that had depended on them. Psychology moved from rational judgment to causal mechanism; law began qualifying individual responsibility with systemic explanation; history relocated causality from agents to structures; ethics stopped asking which moral judgments are correct and began asking why people make them; epistemology exchanged “Is it true?” for “How is it warranted?” The corpus’s sixteen field audits document this propagation field by field. The finding across all sixteen is uniform in kind and variable only in degree: each field retains its classical vocabulary and has lost some or all of its classical capacity.

V. Sterling’s Position

Against this background, the character of Sterling’s work comes into focus. Sterling did not construct a defense of the six commitments as an academic project in the philosophy of religion or metaethics, though his dissertation defended ethical intuitionism against its critics on professional terms. His distinctive achievement, recovered principally from fifteen years of correspondence on the International Stoic Forum, is a working system — a Stoicism in which the classical commitments are not defended as museum pieces but operated, daily, as the presuppositions of a practice.

This gives his position an evidentiary status that'll a purely academic defense could not have. The standard modern posture toward the classical commitments is that they are naive: refuted or superseded, kept alive only by nostalgia or religious attachment. A living system that runs on them — that generates determinate answers to concrete questions of choice, emotion, and character, and does so with internal consistency across thousands of occasions of application — is a standing counterexample to the supersession narrative. The replacements claim to have inherited the estate. Sterling’s Stoicism demonstrates that the original owner is not dead.

It also explains a feature of Sterling’s forum writing that would otherwise seem incidental: his constant engagement with modern interlocutors who import replacement assumptions into Stoic discussion without noticing that they have done so. The most instructive of these engagements is his long exchange with Steve Marquis, a convinced and serious Stoic who nonetheless describes himself as “at heart a pragmatist” and who proposes to secure the Sage’s inerrancy by redefining error from false belief to irrational belief. That is the epistemological replacement — justification-procedure substituted for correspondence — reproduced in miniature, inside Stoicism, by a practitioner of undoubted sincerity. Sterling’s reply, declining the pragmatist label while constructing an alternative that preserves correspondence at the level of appearance, is the classical resistance reproduced at the same scale. The exchange demonstrates that the ultimate context is not a distant backdrop. The contest between the classical structure and its replacements runs through the middle of the Stoic conversation itself, and can only be recognized there by one who holds the larger frame.

VI. The Corpus as an Episode in the Contest

The ultimate context determines what the corpus is. Under the narrow frame, the corpus would be a body of Stoic exegesis and application: instruments for decision-making, analyses of procrastination, readings of literary characters, audits of thinkers — all interesting, none of it more than commentary on a school. Under the ultimate frame, every corpus document is an episode in the contest between the classical structure and its replacements.

The audit instruments make this explicit in their design. The Classical Presupposition Audit examines individual thinkers against the six commitments, not against Stoic doctrine. The Classical Field Audit examines entire disciplines the same way. The Classical Restoration Instrument and the field restoration syntheses ask what each discipline would look like with its classical presuppositions restored. None of these instruments could be formulated at all within the narrow frame, because their criterion is the classical structure as such and their subject matter is the displacement. Stoicism enters them not as the standard of measurement but as the demonstration that the standard can still be met.

The same holds for the corpus documents that appear most narrowly Stoic. A run of the decision framework on a case of grief is, on its surface, an application of Epictetus. In its ultimate context it is a demonstration that the classical account of emotion — emotion as judgment, misery as false assent to a value claim — still generates determinate, livable guidance where the replacement accounts generate management, medication, or validation. The procrastination series is, on its surface, practical psychology. In its ultimate context it is a demonstration that a phenomenon the replacement frameworks treat as a mechanism to be adjusted is fully intelligible as a pattern of judgments for which the agent is responsible and which he can correct. Every applied document carries this double character: local application, and standing evidence in the larger case.

VII. What the Context Requires

Reading the corpus in its ultimate context imposes obligations that the narrow frame does not.

It requires that the six commitments never be treated as one interpretive option among others. Within the narrow frame, a reader might regard Sterling’s substance dualism or his moral realism as his personal metaphysical preferences, detachable from the practical system. The ultimate context forecloses this. The commitments are the classical structure; the practical system is what the structure yields; detaching them reproduces exactly the mechanism of the displacement — keeping the vocabulary while replacing the referents — inside a body of work whose purpose is to resist that mechanism.

It requires vigilance about the replacements’ capacity to enter unannounced. The displacement succeeded historically because it did not announce itself; it will enter any modern discussion of Stoicism the same way, carried by vocabulary that sounds compatible — “what works,” “justified belief,” “constructed meaning,” “coping” — and by interlocutors of complete sincerity. The Marquis exchange is the standing exhibit. The frame is what makes such entries visible.

And it requires that the corpus’s purpose be stated without reduction. The purpose is not the promotion of a school, the curation of an archive, or the refinement of a set of instruments, though it includes all three. The purpose is the recovery, systematic defense, and propagation of the classical structure of Western philosophy in its most complete and most livable form — the form Grant C. Sterling gave it. The history of classical philosophy supplies what was built. The history of the replacements supplies what was lost, and how. Sterling’s Stoicism stands at the junction of the two histories as the demonstration that the loss is not irreversible. That junction is the ultimate context, and everything in the corpus is to be read from it.

The Appearance and the Wager: Sterling and Marquis on the Problem of Pragmatism

The Appearance and the Wager

Sterling and Marquis on the Problem of Pragmatism

Theoretical foundations: Grant C. Sterling (Eastern Illinois University). Analysis and synthesis: Dave Kelly. Prose rendering: Claude (Anthropic). 2026.

In January 2021, on the International Stoic Forum, Steve Marquis and Grant C. Sterling conducted a four-message exchange under the heading “Stoic Pragmatism — a modern approach to the dilemma of what is the right thing to do.” The exchange is short, occasional, and unresolved. It is also a case study in exactly the kind of displacement that the corpus elsewhere traces at civilizational scale: the substitution of justification-procedure for correspondence as the measure of a belief’s standing. What happens between Marquis and Sterling in miniature is what Steve Fuller, writing later about Rorty, describes happening to the whole of Western philosophy. The value of the exchange is that it shows the substitution being resisted, not merely completed — and shows the resistance itself under pressure.

Marquis’s Wager

Marquis opens by recalling an old dispute with Sterling over whether the Stoic Sage requires something approaching omniscience to select the right action. His resolution is a scope restriction. Certainty of fact, he argues, is not available in ordinary deliberation and was never really required — what is required is knowledge of what is significant to the choice, not knowledge of the whole state of the cosmos. He calls this his “free body diagram”: the engineer does not model every force acting on a structure, only the ones that matter to the tolerance in question.

From this Marquis draws his self-description: “I am at heart a pragmatist and this is Stoic pragmatic rationalism.” But the claim is bounded, and the boundary matters. Marquis restricts pragmatic judgment to questions of non-value fact — the empirical circumstances a choice depends on — and explicitly excludes questions of value from the same treatment: “concerning matters of value, we can know with certainty.” He is not proposing that moral truth itself be measured by usefulness. He is proposing that under factual uncertainty, action on what “appears” most probably true, arrived at through something like cost-benefit or risk assessment, satisfies the Stoic requirement of correct judgment without requiring the Sage to be omniscient.

In his second message Marquis extends the point to pathos: much of what makes a choice feel like a genuine dilemma, on his account, is not real balance between options but pathos obstructing what would otherwise be straightforward discrimination. Reduce the pathos, and the apparent dilemma resolves itself. This is consonant with the corpus’s own treatment of pathos as an obstruction to correct judgment rather than a source of moral information — Marquis is not introducing a foreign element here, only applying it to epistemic rather than strictly ethical judgment.

Sterling’s Declination

Sterling’s reply is explicit about where he stands relative to the label: “Although I would not describe myself as a pragmatist, my views are not far from Steve’s here.” He then offers three theories of knowledge, each consistent with an inerrant Sage, each explicitly flagged as his own construction rather than a claim about settled ancient doctrine.

Theory 1, Skeptical Dogmatism, restricts belief to what is certain and permits action without belief for everything else — one can eat the apparent sandwich at the apparent lunch hour without committing to either proposition as believed.

Theory 2, Pragmatic Dogmatism, is Sterling’s formalization of Marquis’s position: it redefines error not as having a false belief but as having an irrational one. The Sage who reasons correctly from her evidence remains inerrant even if the belief she arrives at later proves false, because inerrancy is relocated from the content of the belief to the rationality of the process that produced it.

Theory 3, Internal Content Dogmatism, is the theory Sterling identifies as his own preference. On this account the Sage forms no belief about the external state of the world absent certainty — she believes only about the appearance itself. The oar half-submerged in water appears bent; the Sage does not believe the oar is bent, and does not believe it is straight. She believes “the oar appears bent” and “oars that appear bent in water are often straight” — propositions that are, Sterling notes, certainly true, because they are about the appearing, not about the external fact.

The architectural function of Theory 3 is not incidental. It is the mechanism by which Sterling preserves correspondence (C5) under conditions of practical uncertainty. The belief still corresponds to something real — not to the external state of affairs, which remains unknown, but to the fact of the appearance itself. Nothing is asserted that outruns the evidence, and nothing is surrendered to mere justification-in-the-absence-of-truth. Sterling closes by proposing that the three theories converge on the same practice of ethical choice regardless of which is adopted — a move that settles the practical question without settling the theoretical one.

The Contested Point

Marquis’s reply does not accept the settlement. He grants Theory 1 the most sympathy, reads it as vindicating his own long-standing insistence on withholding judgment absent certainty, and reads Theory 2 as simply a restatement of how the scientific method already operates. But he presses directly on Theory 3: “the statement it ‘appears’ to be the case is always true but a trivial rewording of the pragmatic approach.” His charge is that “appears” functions in Sterling’s usage as a disclaiming device — a way of avoiding commitment to any claim about the external fact while still, in practice, acting exactly as if the appearance were the fact. If that is right, Theory 3 has not escaped the pragmatic maneuver Sterling declines to name himself with; it has only relocated the same maneuver one level down, from belief-about-the-world to belief-about-the-appearance, while cashing out in the identical practice: act on what appears most probably true.

This charge is not answered in the thread. Sterling’s own closing move — that the three theories converge in practice — is available to him before Marquis’s objection arrives, and is not revisited afterward. The exchange ends with the objection standing.

Corpus Significance

The interest of this exchange for the corpus is not biographical. It is structural. “When Philosophy Changed the Subject" traces how Pragmatism, at civilizational scale, substitutes the question “what works” for the question “what is true,” and how that substitution — once made — quietly converts every field it touches from a discipline of recognition into a discipline of construction or justification. Marquis’s Theory 2, endorsed by Sterling as a formalization of Marquis’s own view, performs exactly this substitution at the level of individual epistemic practice: error is redefined from “false belief” to “irrational belief,” and the Sage’s standing is secured by the rationality of her procedure rather than by the truth of her conclusion. That the substitution appears inside an ISF exchange between two convinced Stoics, one of them the corpus’s own theoretical source, indicates that the displacement pressure Fuller describes at the level of academic philosophy operates at the level of individual reasoning as well. It is not confined to professional philosophers changing departments’ assumptions. It recurs wherever an agent under uncertainty must decide what counts as a justified belief.

Marquis’s objection to Theory 3 is best read in this light. He is not simply scoring a rhetorical point. He is asking whether Sterling’s preferred theory actually holds the line against the substitution, or whether “appears” is doing the work that “justified” does in Theory 2 — securing inerrancy by redefining its target rather than by preserving correspondence to the external fact. The corpus does not treat this question as settled by Sterling’s own preference. Whether Internal Content Dogmatism in fact preserves C5 in the relevant sense, or merely relocates the pragmatic substitution one level inward, is left here as an open point in the record rather than resolved by appeal to what Sterling personally favored. The exchange demonstrates the disagreement; it does not adjudicate it.
