I. The Beginning
The distinction is not free-standing. It is a guard on one theorem, and the theorem is stated in Core Stoicism, Section Two:
Th 6) The only things in our control are our beliefs and will, and anything entailed by our beliefs and will.
Everything below is downstream of that sentence, and the sentence is downstream of a problem. Section Two opens with Th3 — all human unhappiness is caused by having a desire or emotional commitment to some outcome, and then that outcome does not result. Line 4 draws the consequence: desiring what is out of your control subjects you to possible unhappiness, and desiring many such things drives the possibility of complete happiness toward zero. Line 5 then draws the verdict — desiring things out of your control is irrational — but draws it conditionally, and Sterling marks the condition in brackets: if it is possible to control your desires.
That bracket is the whole reason Th6 appears where it does. It is not a piece of Stoic scenery placed at the head of the system; it is a debt being paid. Th6 and Th7 together discharge it. Since desires are caused by beliefs about good and evil, and beliefs are in our control, line 8 follows — desires are in our control — and line 9 discharges the conditional: desiring things out of our control is irrational, without qualification.
So Th6 is load-bearing in a precise and narrow way. It is what converts a conditional verdict into an unconditional one. Anything that weakens the term control weakens exactly that conversion, and the negative-happiness argument reverts to a hypothetical about a capacity we may or may not have.
That is the first premise. What follows is derived from it.
II. The Definition, in Sterling’s Words
The term is fixed on the archival record. In the International Stoic Forum thread family titled Making correct use of impressions, a trichotomy-of-control proposal was put — that alongside what we control and what we do not, there is a third category of what we partly control. Sterling’s reply of 30 August 2019 is definitional rather than argumentative:
“‘Control’ means ‘I can make this do what I want it to do, when I want it to do it’. If the thing doesn’t obey me on some occasions, then I don’t control it. I may ‘influence’ it, but I don’t ‘control’ it.”
Two features of this deserve notice before anything is built on it.
It is a stipulation about the word, offered as a report of what the word already means. Sterling is not arguing that control has this property; he is declining to use the word for anything that lacks it. The move is available to him because the argument in Core Stoicism needs the strict sense and does not need the loose one — nothing in Th6 through line 9 does any work if control means substantially affect.
And it introduces the second term. Influence is not a lesser grade of control. It is the name for the relation that obtains everywhere control does not — which is to say, for the agent’s relation to nearly everything, including his own body, which usually obeys and therefore does not obey.
III. What the Strictness Amounts To
Control admits no degrees. A thing either obeys on every occasion or is not controlled at all. The consequence is a partition rather than a spectrum, and the partition line falls at every, not at most.
This produces results that look wrong at first pass and are not. My arm is not in my control. It obeys nearly always, which is exactly the condition Sterling names as influence. The nearly is not a rounding error to be discarded; it is the whole finding. A faculty that answers on ninety-nine occasions and not on the hundredth has already shown what it is, and the ninety-nine tell you nothing about the hundredth.
The strictness is not severity for its own sake. It is what makes the boundary locatable. A degreed boundary has no place to be drawn — every candidate line is arbitrary, since any threshold of reliability could have been set a little higher or lower. A boundary at always is the only one that is not chosen by the person drawing it.
IV. Yielding as an Exercise of Control
The case that appears to refute the definition was pressed by Michael Edelstein in the same exchange. His form of it, on the record of 3 September 2019, is direct: we have some control but not total control over our thoughts, so why does this not add a third type of control? The example that carries it is the addict, who resists on some occasions and yields on others — which looks like the definition’s own criterion returning a verdict of partial control.
Sterling’s answer is a dilemma rather than a concession. Either the addiction is literally overpowering, in which case there is no control whatever, and the case is not an exception to the dichotomy but an instance of its second half; or it is not overpowering, in which case the man could have refused, and the control was entire. There is no third description available for what happened.
Then the sentence that does the work:
“The fact that in situation X I sometimes choose to yield to a temptation and sometimes choose not to yield does not mean that I have partial control, it means either that on some of those occasions I had no control and on others I had full control, or else (more commonly) on some occasions I used my control to yield, and on some I used my control to resist.”
The parenthetical more commonly is not decoration. It states which horn ordinarily obtains. The usual case is not that control came and went; it is that control was present throughout and was used in both directions.
This inverts the ordinary description of a lapse. The man who gives in has not suffered a failure of the faculty. He has operated it. He used the same faculty as the man who held, and used it just as fully — the difference lies in what he used it to do, not in how much of it was available.
Sterling supplies the mechanism that explains why one direction is taken more often without being compelled. Where a man has a habit of seeing something as good, the appearance arrives already valued, and giving in is easy. The training goal he names is not the acquisition of a stronger faculty but the condition of no longer being tempted to yield irrationally. Habit makes one direction cheap. Cheap is not compelled, and the distinction between them is the distinction under discussion.
V. Why the Definition Must Be This Strict
Three separate supports, and they are worth keeping separate because they fail differently.
The argumentative support. Line 8 says desires are in our control. If control is degreed, line 8 is false as stated and true only in a weakened form — desires are substantially influenced by beliefs, which are themselves substantially influenced by us. Line 9 then cannot discharge line 5’s conditional, and the verdict that desiring the uncontrolled is irrational never becomes unconditional. The system does not collapse loudly at this point; it quietly reverts to a hypothesis.
The metaphysical support. Control in the required sense presupposes origination, and Sterling’s most substantial archived statement on the point is his 2021 reply on free will and causation, which proceeds by rejecting Chrysippean compatibilism outright. On the compatibilist account an action is up to us because it is caused in part by our own character. Sterling’s judges make the objection concrete: Able takes a bribe at one figure, Baker at a higher one, Charlie at none. Chrysippus says Able’s acceptance was up to him, since another character would have refused. Sterling’s reply is that Able’s character was not up to him in any robust sense — he began with an initial character that was in no sense his doing, and every subsequent choice and every modification of character follows necessarily from it. He presses the consequence as far as it goes: the same holds of Zeus, who after the Conflagration had a character that caused His first act, and so on. On that view nothing is in anyone’s control, including the gods’.
This matters here because degreed control is compatibilist control wearing different clothing. To say I partly control my assent is to say that my assent issues from a character that is partly my doing — which is Chrysippus’s little dog with a longer tether. Sterling’s positive proposal is what the strict sense requires: physical causation operates by ceteris paribus laws, and Acts of Reason are a genuinely intervening force, not derived from or reducible to physical process. His formulation is that if Reason can make ceteris non paribus, then causation and free will are both parts of one larger nexus. The strict definition of control is the ethical face of that metaphysics.
The practical support. A boundary that cannot be located cannot be used. The whole practice consists in referring an arriving impression to one side or the other, at speed, without deliberation. Does it always obey is answerable. Do I have enough say over this is not, and a practitioner who asks it will answer differently at different hours, depending mostly on how the day is going.
VI. What the Distinction Does Not Do
A refinement from the same September exchange guards against an inference the distinction invites and does not license. Asked whether being in our control is itself what makes something good or bad, Sterling answered that control is a requirement for something’s being good or bad, not a sufficient condition — and that there could be things in his control that do not affect his eudaimonia.
This is worth stating plainly because the collapse it prevents is common and is not the trichotomy. Th6 draws a boundary; it does not confer value on what falls inside. The value work is done by Th10, and the two theorems are joined at line 11 and line 12 — virtue and vice are types of acts of will, therefore in our control; therefore externals are never good or evil. The inference runs from value to control, not from control to value.
So it is in my control does not entail it matters. A practitioner who treats the inner side of the boundary as automatically weighty has produced a second false valuation, this time of internals, and has done it with the framework’s own vocabulary. The distinction between control and influence tells him where his agency is. It does not tell him that everything his agency touches is at stake.
VII. The Third Term of Th6
Th6 does not say that only beliefs and will are in our control. It says beliefs and will and anything entailed by our beliefs and will.
The clause is easy to read past and does real work. Without it the boundary encloses a bare act, and virtue would have to be located somewhere outside it — since virtue is a settled condition of the faculty rather than a single assent, and desires are consequences of beliefs rather than beliefs themselves. Line 8 depends on the clause: desires are in our control because they are caused by beliefs that are, which is a claim about what the beliefs bring with them.
The clause has a limit, and the limit is the word. What is entailed is inside; what is merely produced is not. My body’s execution of my will is not entailed by my will — it usually follows, which is the signature of influence. Sterling makes the same point from the other side in the free-will reply: the vast majority of the time our bodies execute what Reason dictates, though seldom with the ultimate consequences we sought. The vast majority of the time is the language of influence, and it is applied to the very next thing outside the boundary.
VIII. The Collapse
The trichotomy is the collapse in doctrinal form. Three categories — controlled, influenced, external — and the middle one holds a share of what the agent’s happiness rests on.
The damage is immediate. Th2 says it is irrational to accept incomplete happiness if complete happiness is available. Under a trichotomy, complete happiness is not available anywhere, because some of its content sits in a zone that answers on most occasions. Th2 then has nothing to reach for, and the argument that made completeness the standard has no object. The figure this produces is the one worth naming: a Sage internally perfect and still failing, since perfection of the will no longer exhausts what his happiness depends on. That figure is not a Stoic difficulty. It is a Stoicism with the point removed.
The Edelstein record shows the collapse operating alongside a practice that requires the opposite. His stated metaphysics denies free will; his position on control makes control over one’s own thought partial, which under the strict definition is no control at all. Yet his clinical work consists entirely in instructing clients to change their own thinking, and that instruction presupposes an addressee who originates. The finding recorded against him is Inconsistent rather than Contrary for exactly this reason: both halves are load-bearing in their own domain, and neither can be dropped without structural damage to it. A framework in which the client’s thinking is fully determined has no one to talk to.
The commoner form of the collapse is not doctrinal at all. It is a report: I couldn’t help it. Nobody who says this has adopted a trichotomy. But the sentence has the trichotomy’s structure — a zone in which the faculty was present and insufficient — and repeated often enough it installs the position without the position ever being examined.
IX. Holding It Open in Practice
Two diagnostics, one prospective and one retrospective.
Prospectively, the question is not how much say do I have over this but does it obey. The first admits every answer; the second admits one, and usually returns no about everything except assent.
Retrospectively, the finding is nearly always the same and nearly always resisted: I lost control is a false report. Control was present and was used in the direction that cost less. This is what the 3 September passage delivers to a practitioner, and it is more useful than any exhortation, because it relocates the whole question. The man who thinks he lost control looks for a way to have more of it. The man who sees that he used it looks at what made that direction cheap — which is a habit of seeing something as good, which is a false value judgment, which is the thing the system knows how to correct.
One guard, because the finding is sharp and can be misused. I used my control to yield is a description, not a charge. Self-reproach over it is a fresh false judgment, this time about a past external, and it produces a second failure on top of the first. The strictness of the definition is what makes the correction possible; it is not a stick.
X. What Remains Open
Three entries, made rather than smoothed.
Whether Sterling anywhere treats control as admitting a difference between the faculty and its exercise. His 15 August 2019 formulation — that making the right use of impressions is the only thing we control — reads as compression against the two passages developed here, but compression and position are distinguishable only by more of his text, and twenty-two threads in this family remain unretrieved.
A hedge in the free-will reply. Describing Acts of Reason, Sterling writes that the choice is guided by our character and preferences but not dictated by them — except perhaps in cases where we have strong reasons to do X and virtually no reason to do anything else. Read strictly, a case in which the act is dictated is a case of no control, which fits the first horn of the addiction dilemma rather than contradicting the definition. But the exception is hedged with perhaps, it is not developed, and it is the only place in the retrieved record where Sterling gestures at an occasion of dictated assent that is not compulsion. It is entered here as an open question about his position, not as a defect in it.
And whether genuinely overpowering compulsion ever in fact occurs. The dilemma is exhaustive without being decidable case by case: it tells the agent that one of two things was true, and gives him no procedure for determining which. Sterling’s own weighting — more commonly, the second horn — is a judgment about frequency, not a criterion. For practice this matters less than it appears, since the agent who cannot tell which horn he is on should proceed on the assumption that he could have refused; the opposite assumption is unfalsifiable and costs him the correction.
