Stoic Apologetics — The Case for the Doctrines, from Epictetus and Sterling — Version 0.1

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


Prefatory Note

Sterling named this work himself. Closing his first message to Jules Evans on the International Stoic Forum, 25 February 2008, he wrote that whatever contributions he might make would have to come in the area of convincing people that Stoicism is true — “Stoic Apologetics”, if you will.

This document is built for that use. Its nine sections are self-contained. Any one can be lifted into a discussion without carrying the others. The sources are Epictetus in Oldfather’s translation, Sterling’s Core Stoicism of 19 September 2005, his three-part exchange with Evans of 25 February 2008, and his enumeration of the required belief set of 3 March 2009.


I. What Is Being Denied

State the opposing position fairly first, because it is held by serious people and because a caricature persuades no one.

The position runs like this. Stoicism’s lasting contribution is a set of practices: examining one’s thoughts, distinguishing what one can affect from what one cannot, rehearsing misfortune in advance, keeping a journal, returning attention to the present. These practices work. They have been tested in clinical settings and have helped enormous numbers of people. The metaphysics behind them — the claim that only virtue is good, that externals carry no value whatever, that the sage feels no grief — is a historical wrapper. It belongs to a dead cosmology. Insisting on it turns a living practice into a creed, drives newcomers away, and substitutes doctrinal policing for the work itself.

There is a further charge, usually unstated. Someone who presses the doctrines is understood to be claiming membership authority — deciding who counts. The reaction is not primarily intellectual. It is a reaction to being told one is not the thing one thought one was.

The apologist should concede everything in that position that is true. The practices do help. Technical vocabulary is not required. Sterling says both things explicitly and repeatedly. What he denies is the separability claim: that the practices carry Stoic content when detached from the beliefs that generate them, and that they do the work they do for reasons other than the beliefs.

That is the point in dispute. Not whether newcomers should be lectured. Whether the technique survives the removal of the doctrine.


II. The First Sentence

The strongest evidence is the shape of the Enchiridion itself.

Section 1 does not open with an exercise. It opens with a claim about the world: some things are under our control, others are not. Under our control are conception, choice, desire, aversion, everything that is our own doing. Not under our control are the body, property, reputation, office. Then a second claim, about the natures of those two classes — what is ours is by nature free, unhindered, unimpeded; what is not ours is weak, servile, subject to hindrance. Then a third, conditional and consequential: if you take what is naturally slavish to be free, and what is not your own to be your own, you will be hampered, will grieve, will be in turmoil, and will blame both gods and men.

Three propositions before any instruction appears. And when the instruction does appear at the end of that section — say to every harsh external impression that it is not what it appears to be, then test it by the rules you have — the instruction is explicitly parasitic on the propositions. The first and most important of the rules just is the dichotomy stated at the top. The technique is an application procedure for a doctrine. Remove the doctrine and there is no rule to test the impression against.

Section 5 is the same structure compressed:

It is not the things themselves that disturb men, but their judgements about these things.

This is the sentence most often quoted on the groups in question, and it is a doctrinal assertion about the causation of distress. It is not advice. It has a truth value. It is either the case that events lack the power to disturb, or it is not.

Section 2 states what desire and aversion promise and what happens when they miss — he who fails in his desire is unfortunate, he who falls into what he would avoid experiences misfortune — and then instructs the reader to withdraw aversion from everything not under our control, and for the time being to remove desire utterly. That instruction is unintelligible except on the prior claim that the objects of those desires are not worth having in the way one took them to be.

Section 3 tells the reader to say of the jug that it is a jug, and of the child that he is a human being, so that he will not be disturbed when it breaks or when he dies. Section 4 tells the reader going to the baths to want two things — the bath, and to keep his moral purpose in harmony with nature — so that a spoiled bath leaves the second want intact. Section 30 measures duties by social relationship and adds that no one will harm you without your consent; you will have been harmed only when you think you are harmed.

Sterling’s own account of what the first five sections deliver, from Harshness and Beauty in Epictetus: the distinction is sharp, “harsh” — things not in our control are enslaved, things in our control are free — and we are enslaved to external things only because we enslave ourselves. He notes what is absent from those sections: no pantheism, no fiery pneuma, no Chrysippean determinism. What is present is the dichotomy and real good and bad all on one side of the chasm. And, he says, the harshness is part of the beauty: eudaimonia is not reached by holding the old view and making small modifications, which only makes the chains more comfortable.

The apologetic point is narrow and should be pressed narrowly. Whatever one concludes about the doctrines, one cannot claim that Epictetus offered techniques and left the doctrines to taste. He put the doctrines first, made the techniques depend on them, and stated the dependence.


III. Theorem 6 — What Is Actually Ours

Core Stoicism, Theorem 6: the only things in our control are our beliefs and will, and anything entailed by our beliefs and will.

This is the proposition standing behind Enchiridion 1. It is worth separating two things that get run together in discussion.

The first is a scope claim: the class of things genuinely up to us is much smaller than people assume, and consists of inner events. Not outcomes. Not other people. Not the body. Not reputation. Not, strictly, even our actions considered as completed events in the world, since their completion depends on conditions outside us. What remains is judgement and will.

The second is a substantive claim: that this small class is genuinely up to us. Really originative. Not the felt sense of freedom accompanying a process determined elsewhere.

Most contemporary sympathy attaches to the first and quietly drops the second. But the second is what makes the first useful. If judgement is itself produced by prior causes running back through temperament, upbringing, and neurochemistry, then “focus on what you control” reduces to focus on a different region of the same causal net, and the promise in Enchiridion 1 — that no one will be able to compel you, that you will do absolutely nothing against your will — is false. Epictetus is not describing a shift of attention. He is describing a location in reality where the agent is the origin.

In corpus terms, Theorem 6 rests on Commitment 1, Substance Dualism, and Commitment 2, Libertarian Free Will. The apologist need not use those labels on a discussion board. He does need to know that when an interlocutor says he accepts the dichotomy but is a thoroughgoing determinist and a physicalist about mind, the interlocutor has not accepted the dichotomy. He has accepted a redescription of it that cannot carry the weight Epictetus puts on it.

A useful way to put the question to someone: when you assent to an impression, is that assent something you do, or something that happens in you? Stoicism requires the first answer. Every consolation in the Enchiridion follows from the first answer and collapses under the second.


IV. Theorem 10 — Only Virtue Is Good

Core Stoicism, Theorem 10: the only thing actually good is virtue, the only thing actually evil is vice. Theorem 12 follows immediately: things not in our control are never good or evil.

This is the doctrine that gets refused. It is also the one for which Sterling supplies the single strongest apologetic lever available, and the apologist should have it memorized.

Evans put to him the standard concession — that the core insight, that suffering comes from our thoughts rather than externals, is easy to accept and practically useful, and that Stoicism survived because of that insight rather than because of the more radical idea that the only source of happiness is inner virtue.

Sterling’s reply, from Part Three of the exchange:

The belief that our suffering comes from our own thoughts and not from externals is equivalent to the belief that externals are neither good nor evil. If externals were genuine goods or evils, then our perception of a genuine evil would cause suffering, as would the loss or absence of a genuine good.

Set that out as the argument it is.

  • Premise, granted by the interlocutor: externals do not cause suffering; judgements do.
  • Premise: if something were genuinely evil, then encountering it would warrant suffering, and losing something genuinely good would warrant suffering.
  • Therefore: no external is genuinely evil, and none is genuinely good.

The person who accepts the popular half of Stoicism has already accepted the conclusion he thinks he is rejecting. He has simply not been shown the derivation. This is the most productive single move in the whole apologetic, because it does not ask him to adopt a new commitment. It asks him to notice one he already holds.

Sterling adds a second observation in the same message that is worth carrying alongside it. It would be a shame, he says, to teach someone that externals have no value and not teach him that virtue does have value; it would be odd to teach that suffering comes from our beliefs and not teach that happiness comes from having the proper beliefs. He sees no reason the more radical claim should be hard to swallow for anyone who swallowed the core insight.

The asymmetry is the thing to press. Half the doctrine leaves a person with a world emptied of value and nothing put in its place. That is not a gentler Stoicism. It is a bleaker one. The full doctrine is the part that says where value actually is.

Theorem 10 rests on Commitment 6, Moral Realism, and is known in the way Commitment 3, Ethical Intuitionism, describes. Value is a feature of reality, not a projection, and the claim that only virtue is good is either true of that reality or false of it.


V. The Interlock

Sterling closed Core Stoicism with a warning aimed precisely at the position this document answers. He calls it Smorgasbord Stoicism.

He grants the legitimate part first, and the apologist should always grant it in the same order. One should never accept everything a theory says if one has reason to think some of it false, nor reject all of a theory if one has reason to think parts of it correct. Selective acceptance is not in itself a vice.

The danger is structural. The core ideas interconnect, and denying one principle may undermine support for others, so that the very things one sought to preserve fall apart.

He then gives the worked case. Deny Theorem 7 — that desires are caused by judgements about good and evil — and propositions 8, 9, 13, 14, 28, and 29 all collapse. You lose the claim that desires are in our control, which means you lose the claim that it is irrational to desire externals, which means you cannot control your happiness, which means you lose the argument that desiring acts are not virtuous. Denying one theorem, in his phrase, makes the whole house of cards crumble into dust.

He also shows the contrast case, which matters for credibility. Deny Theorem 20 or 21 — that the universe is or is governed by Nature, Providence, God or the gods, and that what is so governed is exactly as it should be — and a great deal of the account of positive happiness is undermined, but the account of virtue and of the avoidance of unhappiness is not seriously damaged. Some denials are local. Others are load-bearing.

So the apologist’s claim to the groups is not that the corpus is a package deal to be swallowed whole. It is that there is a dependency structure, that Theorems 6, 7, and 10 sit near the bottom of it, and that the practices everyone values sit near the top. You may drop the theology and keep the practice. You may not drop Theorem 7 and keep the practice, because the practice is an application of Theorem 7.

Someone who challenges a negative thought without believing that the thought is false, and false because externals lack value, is not applying Stoic doctrine to his distress. He is doing something else that resembles it from the outside.


VI. Nine Objections

Sterling anticipated most of these himself, and reported in Part One that friends and students raise them in this order.

1. “This would make me an emotional zombie.” Sterling names this as the first question the neighbour asks. The answer is the doctrine of eupatheia — that the Stoic account is not the removal of feeling but the removal of feeling grounded in false judgement, with appropriate positive feeling remaining and in fact increasing.

Core Stoicism supplies three sources of it. Proposition 17: correct judgement and correct will produce appropriate positive feelings. Theorems 18 and 19: some positive feelings do not arise from desires at all — the taste of a meal, the sight of a sunset — and are therefore not irrational. Proposition 23: the Stoic is positively happy in at least three ways, through appreciation of his own virtue, through physical and sensory pleasure, and through appreciation of the world as it is, the last of which is continuously available, since at every waking moment one can perceive something as being what it is.

The zombie objection assumes that the alternative to distress is flatness. The doctrine says the alternative to distress is joy, and that distress was never the price of caring.

2. “Then why do anything? Why eat?” Sterling names this as the second question, and answers it with the doctrine of preferred indifferents.

Theorem 24: an act of will must have content, composed of the result at which one aims. Theorem 25: some things are appropriate objects at which to aim although they are not genuinely good. Theorem 26 names them — life, health, pleasure, knowledge, justice, truth-telling. Theorem 29: virtue consists of the pursuit of appropriate objects of aim, not the pursuit of the objects of our desires.

The distinction to hold in front of the objector is between aim and desire. Aiming at health is rational. Desiring health, in the technical sense that involves judging health to be genuinely good, is not. The Stoic takes the safer road rather than the icy one. He is not performing. He is aiming rationally at a preferred indifferent while holding no desire that he arrive and no dread of ice as a genuine evil.

Sterling’s own worked example:

I should report truthfully to my boss regarding the sales numbers from the last quarter: truth-telling is virtuous, and I have a duty to act faithfully at work. If my boss fires me, I should remember that my job is an external, neither good nor evil.

The reserve clause is not decoration. The moment one begins to require the preferred outcome, the preferred indifferent has been converted back into an object of desire and the false judgement has re-entered.

3. “I cannot change my desires.” Sterling’s answer in Part One: explain, in whatever words you choose, that desires follow from beliefs about value, that such beliefs are in our control, and that one can refuse to assent to the impression that one has been harmed.

This is Theorem 7 joined to Theorem 6, and it is worth noting that the objection concedes the argument. Someone who says he cannot change his desires is asserting that his desires are not up to him, which is a denial of Theorem 8 by way of denying Theorem 6 or 7. He is not reporting a practical difficulty. He is stating a competing doctrine. Ask him which of the two he is denying.

4. “Stoicism is a cure, not an immunization. People recover using it.” Evans made this objection with Cicero as the example. Sterling’s reply: not without changing their beliefs, they didn’t. And on Cicero specifically — if he had fully accepted Stoic teachings before his daughter died, he would not have had the breakdown.

Sterling’s formulation of the underlying picture is exact and worth quoting to a group:

We are sick in the sense that we have an underlying condition that breaks out in incidents of distress. No real cure for the distress exists that doesn’t address the underlying condition.

Note what this concedes. Recovery after the fact is possible. What Sterling denies is that it occurs without doctrinal change. The recovery is the doctrinal change, arriving late.

5. “CBT and REBT prove the techniques work without the doctrine.” Sterling’s reply in Part Three: the success CBT has had is the result of incorporating Stoic doctrine, and he sees no reason to suppose it would have less success or popularity if it incorporated more.

And his diagnostic question: train oneself to stay mindful of what? Keep thought journals about what? Every one of the techniques either reflects the underlying doctrine — we challenge negative thoughts because those thoughts rest on the false belief that externals have value — or else is not distinctively Stoic at all, since many systems recommend staying mindful of something.

His comparison is Freud. Freudian psychotherapy rests on Freudian doctrines about the unconscious and repression, exactly as Stoic practice rests on Stoic doctrine. The difference, he says, is that Freudian therapy does not work, because the underlying doctrines are false.

The clinical evidence is therefore evidence for the apologist’s side. A method that works because a belief is true is a method whose success testifies to the belief.

6. “This is dogmatism. Philosophy should be inquiry, not creed.” Distinguish two things. Requiring that a person hold beliefs he has not examined is dogmatism. Observing that a system consists of propositions, that propositions have truth values, and that a system’s benefits follow from its propositions being true, is not dogmatism. It is the ordinary condition of holding a view about anything.

Sterling’s whole method in the Evans exchange is argument. He does not assert the doctrines and demand assent. He derives Theorem 10 from a premise Evans already granted. That is inquiry conducted to a conclusion, which is what inquiry is for.

Underneath the objection is usually Commitment 5, the Correspondence Theory of Truth. If an impression is a truth-apt claim about how things stand, then what one believes about value determines whether one’s assent is correct, and the question of which beliefs are true is unavoidable. If it is not truth-apt, if it is merely a stance one adopts because it helps, then nothing in Epictetus can do what Epictetus says it does. There is no third option in which the doctrines are optional but the promises still hold.

7. “Epictetus didn’t require the metaphysics, so why should you?” Concede this one, and concede it enthusiastically, because it is largely correct and conceding it narrows the ask.

Sterling’s observation about the first five sections is that they contain no pantheism, no theism of any kind, no fiery pneuma, no Chrysippean determinism, and no metaphysics beyond the dichotomy of internals and externals with real good and bad all on one side.

And in the 2009 message he says it in the first person. He names pantheism, materialism, determinism, and divine Providence as principles classical Stoicism could add, and holds none of them critical to whether someone counts as a Stoic. He cites Epictetus as surely a Stoic while doubting he was a pantheist. He states that he is himself neither a pantheist, nor a materialist, nor a determinist.

So the person objecting to the ancient cosmology is objecting to something the apologist is not asking him to accept. Say so plainly. Then return to what is being asked.

8. “Who gets to decide who counts as a Stoic?” The honest answer is that nobody polices membership, and the apologist should not pretend to. What can be said is narrower and harder to refuse: a term has content, and the content is what makes the claims about the term true.

Sterling’s own formulation in 2009 is characteristically mild — that someone who accepts all five beliefs may reasonably be called a Stoic, and that someone who rejects most of them may not. That is a claim about language tracking substance, not a claim about credentials.

The apologist’s real interest is not the label anyway. It is whether the person gets the result. Somebody who keeps the techniques and drops Theorems 6, 7, and 10 will not get the result, and what he calls himself while not getting it is a secondary matter.

9. “The doctrine is cold. It asks me to stop loving my child.” Enchiridion 3 is the passage that generates this, and it is the passage on which the most damage is done by careless quotation.

The instruction is to say, when you kiss your child, that you are kissing a human being — so that when he dies you will not be disturbed. It does not say to withhold the kiss. It does not say to feel nothing at the kiss. It says to know what kind of thing you are holding.

The agent who has removed desire for externals but retains the capacity to distinguish preferred from dispreferred will act, in most cases, very much like an ordinary person of sound judgement. He will seek food, keep his health, keep his promises, tell the truth, care for his family. What is absent is the emotional stake in outcomes. And it is absent not because he has become cold but because he has stopped making false judgements.

Sterling’s version of the same point, against Evans’s charge that pure Stoic therapy would tell the lonely person that a partner is an indifferent and he should accept the will of the Logos instead of changing his situation: this is false, and it is a misunderstanding of the nature of goodness resulting from not understanding preferred indifferents. Pure Stoic therapy would tell him no such thing — though it would tell him to accept the will of the Logos if he tries to meet someone and fails.


VII. What Is Not Being Asked

Before making the ask, clear the ground. On Sterling’s account, none of the following is required in order to be a Stoic:

Pantheism. Materialism. Determinism. Divine Providence. Ancient physics of any description. The pneuma. The conflagration. Belief that the sage has ever existed. Technical Greek vocabulary. Agreement with everything Chrysippus held. Agreement with everything Sterling holds.

The 2009 message is explicit that these further principles are ones classical Stoicism could add and that none is critical to the membership question, and that Sterling himself is not a pantheist, materialist, or determinist. Epictetus, whom he takes to be surely a Stoic, he doubts was a pantheist.

State the exclusion list before the inclusion list. Most of the hostility on those groups is aimed at items on the exclusion list, and much of it dissolves once the target is correctly identified.


VIII. The Five Beliefs

On 3 March 2009, answering a direct question about what makes someone a Stoic, Sterling enumerated the beliefs in plain language, without technical vocabulary. As rendered in the corpus record:

  • That happiness is found exclusively in virtue.
  • That things not in our control are neither good nor evil.
  • That the only things we control are inner events — beliefs, desires, act of will.
  • That emotions arise from false beliefs that external things have value.
  • That virtue is the only genuine good and vice the only genuine evil.

He held that someone accepting all five may reasonably be called a Stoic, and that a sixth candidate — that no one should be distressed by any external occurrence — is derivable from the five rather than additional to them.

Item three is Theorem 6. Item four is Theorem 7. Item five is Theorem 10. Item two is derived from them. Item one carries the eudaimonia claim. The list is not a separate creed standing outside Core Stoicism. It is the load-bearing spine of Core Stoicism, stated for someone who has never read a theorem.

Two things follow for the apologist.

First, the ask is short. Five sentences, no jargon, no cosmology. It can be put in a single post.

Second, the ask is not a ranking claim. Sterling’s position in the Evans exchange is a necessity claim: the psychology is parasitic on the philosophy, and nothing remotely Stoic survives the removal of the core beliefs. He is not saying that believing doctrine is the most important thing a person can do, or that it competes with virtue for first place. Only virtue is genuinely good. Since virtue is correct assent, and the settled core beliefs are what make an arriving value-impression receive correct assent, believing the doctrine is not a gateway standing outside the condition. It is the faculty in that condition, described at a different grain.

That distinction matters in argument. The apologist who says doctrine is the most important thing will be heard as ranking creed above conduct, and will deserve the reply he gets. The apologist who says nothing Stoic survives the removal of the doctrine has said what Sterling actually holds and has said something much harder to answer.


IX. The Apologist’s Own Position

The last section is for the apologist rather than his audience, and it is the one to read before posting rather than after.

The reception of the argument is an external. Whether the group agrees, whether the thread is locked, whether the reply is contemptuous, whether anyone changes his mind — none of this is in the class named by Theorem 6. It is not up to him. If he stakes his equanimity on persuading anyone, he has converted a preferred indifferent into an object of desire and made the false value judgement he is arguing against, in the act of arguing against it. That failure is available on every post, and it is the characteristic failure of apologists.

What is up to him is the aim. Truth-telling is named in Theorem 26 as an appropriate object of aim. So is knowledge. He aims at stating the doctrine accurately, at representing the opposing position without caricature, at conceding what is true in it, and at arguing rather than asserting. Those are within his control and are the whole of what is within it. Whether the argument lands is in the hands of Providence, as Enchiridion 4 has it: he wanted to take the bath, and he wanted also to keep his moral purpose in harmony with nature, and the second want is not spoiled by the splashing.

Enchiridion 30 supplies the manner. Duties are measured by social relationships; one considers not what the other man is doing but what one will have to do if one’s own moral purpose is to be in harmony with nature. Sterling’s neighbour, in Part One, is not a target. He is a neighbour. The person on the group who says the doctrine is dogmatism is not an opponent to be defeated. He is someone who has half the argument and has not been shown the rest.

And Enchiridion 5 supplies the discipline. It is not the things themselves that disturb men, but their judgements about them; it is the part of an uneducated person to blame others where he himself fares ill. If a thread goes badly and the apologist is irritated, the irritation is not caused by the thread. It is caused by a judgement he made, which is his, which is in his control, and which he can decline to make again tomorrow.

Sterling’s assessment of the whole enterprise, from Part One, is worth keeping in view because it is unflattering to the apologist’s hopes and accurate about them: if your problem is dealing with the suffering of someone not able to consider these truths rationally, then Stoicism has nothing to offer you — and, if Stoicism is true, you will look elsewhere in vain.

The apologist does not control who is ready. He controls whether what he says is true, and whether it is said well.
