From “Purely Intellectual” to Sensory Confusion, and Against “Minimal” Objective Reality

Cold Sensation as the Test Case:
From “Purely Intellectual” to Sensory Confusion, and
Descartes Against “Minimal” Objective Reality

with ChatGPT 5.2 Thinking — Revised Edition

Dr. David C. Ring

Introduction

The cold sensation has always been the most exposed nerve in Descartes’s theory of ideas. It is where his representational vocabulary—objective reality, material falsity, the material/objective distinction—comes under the greatest internal pressure, and where the most influential contemporary readers (Wells, Wee, De Rosa, and in a different register Simmons and Schmitter) have tried to rescue Descartes by letting sensations carry some attenuated or “minimal” objective reality¹Martial Gueroult  supports the minimal objective reality thesis in  Descartes selon L’Ordre des Raisons. Vol 1: The Soul and God. Paris: Aubier, 1952. Translated by Roger Ariew   as Descartes’ Philosophy Interpreted According to the Order of Reasons, Vol. 1: The Soul and God when he writes: “From the perspective of being, it is materially an objective reality infinitely small, certainly as close as possible to zero, but not reducible to it and preserving something positive.” (220) “No doubt, the objective reality of the sensible idea is only a minimum; . . . .” (220) “It [objective reality] will lead to the unfolding of the whole range of objective realities, from the highest, that is, from the absolute maximum where it is infinite (God), down to the minimum, where it is the limit of being and nothingness, . . . . “ (221).

of corporeality.

On their readings, the cold sensation represents something corporeal, whatever it may be—enough to count as representational, not enough to generate the misrepresentation problems that Arnauld pressed in the Fourth Objections. This post argues that the minimal-OR reading cannot be sustained, and that Descartes’s own characterization of the cold sensation, when examined with the right diagnostic apparatus, commits him to the stronger verdict: the cold sensation has no objective reality at all—not diminished, not minimal, not thin, but none.

The argument proceeds indirectly, through a test case. Rather than beginning with cold, I ask ChatGPT-5.2 Thinking to adjudicate a prior scenario: a subject, “René,” who reports a “purely intellectual” idea whose content he cannot determine, at the moment of entertaining it, to be of X, of not-X, or of neither. The value of the mystery-idea scenario is that it forces the material/objective equivocation into the open before the cold case is even on the table. Once the model concedes that René’s state is at most an idea taken materially (idea-m)—a formally real mode of thinking with no internally object-fixing content, and therefore a prime candidate for Descartes’s classification as obscure, confused, sensory-family, and materially false—the structural verdict on cold is pre-loaded. Cold is characterized by Descartes in precisely the same terms: the meditator cannot determine, from the sensation itself, whether it is of a real quality, a privation, both, or neither. What follows for René follows for cold.

Two further moves complete the post. First, I consider the standard defender’s retreat—that the cold sensation carries “minimal OR” of corporeality as a candidate cause, even if nothing more determinate—and I push the God-deceiver objection against it. The exchange that follows is instructive: the model correctly notes that my initial form of the God-deceiver argument overreaches, because Cartesian passivity does not entail compelled assent and error properly belongs to the will. I accept the correction and, in the revised first reaction included below, reframe the theodicy argument structurally: Descartes’s divine-veracity guarantee exonerates God from the unreliability of sensations only on the assumption that sensations do not carry determinate internal OR-content of bodies. The minimal-OR reading collapses that exoneration and requires a theodicy Descartes does not supply. Second, and more decisively, I develop with the model the underdetermination argument: an idea whose deliverance cannot settle even the polarity X / not-X / neither cannot, on Descartes’s own definition of objective reality as a measure of a determinate representatum-type internally contained, be carrying OR-content of anything—including, a fortiori, of corporeality. This is the cleaner knockout, and it is the one the post foregrounds.

The closing coda formalizes the distinction that, in my view, dissolves the minimal-OR temptation once and for all: the distinction between idea-r-int (internal representation—the determinate internal containment of a representatum that Descartes’s doctrine of objective reality actually measures) and idea-r-ext (external signification—the lawful, teleological, nature-instituted correlation between a mental state and a bodily condition). The cold sensation has at most idea-r-ext. Idea-r-ext is not a thin species of OR; it is not OR at all. Once that distinction is held firm, “minimal OR” has nowhere to live.

The Mystery-Idea Scenario

Dr. Ring:

Without referring to my DTOI baseline, but only using your own independent interpretation and understanding of Descartes’s theory of ideas, what do you suppose Descartes’s reaction would be to the following scenario?

A person named René has what he calls a specific mental state that he calls his mystery idea. René’s mystery idea is a non-sensory, purely intellectual, specific mental state in the sense that it is one idea. This singular mystery idea has the following properties. René informs us that his mystery idea is such that he cannot determine when he is thinking his mystery idea, whether it is an idea of X, not X, or neither one.

What do you suppose Descartes would believe and say about René’s mystery idea?

ChatGPT 5.2 Thinking:

Descartes would resist the description as given on two fronts: (1) the claim that the state is “purely intellectual” in the robust sense that matters for his epistemology, and (2) the claim that it is one determinate idea while being such that, at the very moment of entertaining it, the subject cannot tell whether it is of X, not-X, or neither.

1) First reaction: this is not behaving like an intellectual idea at all

For Descartes, the intellectual ideas that do real work in metaphysics—extension, thought, substance, God, triangle, equality, etc.—are precisely the ones that can be grasped as something: they have an essence that can be attended to, analyzed, and thereby rendered clearer and more distinct. “Purely intellectual” is not a label that floats free of this normative profile; it is tied to the idea’s susceptibility to intellection, i.e., to articulation of what is being presented and why it is what it is.

So if René says: when I have it, I cannot determine whether it is of X, or not-X, or neither, Descartes will suspect that what is being called “purely intellectual” is really one of these instead:

• a confused deliverance of imagination or sense (even if René calls it non-sensory),
• a merely verbal token—an internal “sound” or mark—mistaken for a genuine idea,
• or a complex, shifting cluster of thoughts being treated as a single unified item.

On Descartes’s way of sorting mental phenomena, the inability to fix even the polarity X vs not-X is a red flag that the state lacks the kind of determinate content that earns the title “idea” in the strict, representationally action-guiding sense relevant to knowledge.

2) Second reaction: the “one idea” claim collapses under scrutiny

Descartes is methodologically ruthless about individuation by content and function. If “the same” supposed idea can equally be taken as presenting X, not-X, or neither, that suggests either:

• it is not one idea but multiple ideas sliding under one name, or
• it is one mode of consciousness whose content is not fixed enough to count as presenting any definite object at all.

Descartes would press: what makes it this idea rather than another? If the only answer is “it’s the one I call ‘mystery idea,'” he will treat it as a naming achievement, not an intellectual apprehension of an essence.

3) What would Descartes say it represents?

Here Descartes’s most characteristic move is: do not infer representational content from mere phenomenological presence. A thought can be occurrent and vivid and yet fail to determine a representatum.

So he would likely say one of the following (with increasing severity):

• At best: it represents something indeterminately, and so is useless for inquiry. It might be a thought of “something or other,” but if it cannot be specified as X, not-X, or neither, it lacks the determinacy required for inference.
• More likely: it is not an intellectual idea but a confused mode—hence not fit to ground judgment. Where clarity and distinctness fail, suspend judgment.
• Most severe: it is an “empty” thought in the sense of being a mere sign with no grasped content. People often mistake facility with a word (or a mental label) for possession of an idea.

4) Would Descartes call it false?

Not in the straightforward sense. Descartes’s official line is that ideas, considered just as ideas, are not the right kind of thing to be false; falsity properly belongs to judgments. The immediate Cartesian verdict would therefore be:

• the state is epistemically defective (obscure/confused/indeterminate), and
• René is not entitled to judge anything on its basis.

If René goes further—”therefore X exists” or “therefore not-X”—Descartes will say the error is in the assent, not in the bare occurrence of the thought.

5) The practical Cartesian prescription

• Analysis route: attempt to decompose the state until something determinate is grasped. If successful, then the “mystery idea” was never primitive; it was a confused composite.
• Bracketing route: if analysis fails, treat it as cognitively idle—exclude it from proofs, definitions, and metaphysical commitments.

Bottom line

Descartes would not romanticize “mystery” here. He would treat the inability to determine X / not-X / neither at the time of thinking as decisive evidence that René either (a) does not have a genuinely intellectual idea with determinate content, or (b) is mistakenly reifying a merely occurrent mental mark into an “idea.” In either case, Descartes would say: suspend judgment, refuse to build on it, and either analyze it into clear components or discard it from the project of knowledge.

The Material/Objective Equivocation

Dr. Ring:

While I agree with your analysis, there is a relevant topic related to René’s mystery idea that you did not mention. What might that be when we are specifically dealing with Descartes’s theory of ideas?

ChatGPT 5.2 Thinking:

The missing, load-bearing topic is Descartes’s equivocation in “idea”—the distinction between an idea taken materially (as a mode/act of thinking) and an idea taken objectively (as what is represented in the intellect, i.e., the representatum “in” the idea, with its degree of objective reality).

“My reply is that there is an ambiguity here in the word ‘idea’. ‘Idea’ can be taken materially, as an operation of the intellect, in which case it cannot be said to be more perfect than me. Alternatively, it can be taken objectively, as the thing represented by that operation; and this thing, even if it is not regarded as existing outside the intellect, can still, in virtue of its essence, be more perfect than myself.” (AT VII 8; CSM II 7)

In Descartes’s theory of ideas, René’s report forces exactly this question: which “idea” is René talking about?

• If “idea” is taken materially (act/mode): Descartes can happily grant that René has some determinate occurrent mental modification—a token episode with formal reality as a mode of mind, whether or not it determines any object.
• If “idea” is taken objectively (represented object/content): Then René’s inability to discriminate X / not-X / neither is strong evidence that the thought does not determine a representatum. Objective reality is a measure of represented object-type. If nothing determinate is being represented, there is no determinate objective content to measure.

Descartes’s pressure point is: Are we dealing with a mere mode of consciousness, or with an idea that contains an object objectively? If it is the former, the puzzlement is unsurprising. If it is the latter, René’s own report undercuts the claim that it is a genuine intellectual idea with determinate objective content.

The Cartesian Conclusion About René’s Mystery Idea

Dr. Ring:

Yes, you have put your finger on it. That is the missing and relevant material not included in your first response. However, I am now interested in one more issue related to this new material, and we can now include my DTOI baseline 2026 here. What is a likely conclusion Descartes might reach, given what we have determined about René’s mystery idea to this point?

ChatGPT 5.2 Thinking:

A likely Cartesian conclusion—now stated in your DTOI vocabulary—is: René’s “mystery idea” is at most an idea-m (a formally real mode of thinking) and not an idea-or (no idea-r-int, i.e., no internally object-fixing content/OR). Therefore it cannot legitimately function as evidence, a premise, or a ground for assent about X, not-X, or anything else; the only warranted judgment is about the occurrence of the mental modification itself.

Why Descartes would land there:

• René’s own report blocks idea-r-int: If he “cannot determine whether it is of X, not-X, or neither,” the state fails the minimal condition for being an objectively contentful representans in the strict sense.
• So the best classification is “material” only: There is a real mental event—idea-m—with formal reality as a mode. But it has no objective reality.
• Epistemic upshot: suspension of judgment is mandatory. Any move from the episode to claims about X would be an illegitimate export of content from the act to the world.

Dr. Ring:

So, when you write that the mystery idea has no ‘usable OR-content,’ what is another stronger way to state this point?

ChatGPT 5.2 Thinking:

A stronger Cartesian (and DTOI-consistent) way to state it is: there is no OR-content there at all—no idea-or, i.e., no idea-r-int—because the “mystery idea” fails to determine any representatum in the intellect. So it is not that the objective reality is present but “not usable”; rather, the episode is merely idea-m (formally real as a mode of thought) with zero objective reality in the Scholastic-Cartesian sense.

Classification of the Mystery Idea

Dr. Ring:

Given everything we have determined so far, what classification would Descartes himself likely claim René’s mystery idea has?

ChatGPT 5.2 Thinking:

Descartes would most likely classify René’s “mystery idea” as an idea taken materially—a mode/act of thinking (idea-m)—and would deny that it is an idea taken objectively in the strict sense, i.e., he would deny that it is an idea-or (no idea-r-int, hence no determinate representatum objectively in the intellect).

• Ontology: a formally real modification of mind (a cogitatio), fully real as a mode.
• Semantics/representation: no internally object-fixing objective content (no objective being of a determinate representatum, hence no OR).

Dr. Ring:

So, you do think that René’s mystery idea is a possible idea in Descartes’s ontology, correct?

ChatGPT 5.2 Thinking:

Yes—but only in the “material” sense. In Descartes’s ontology it is perfectly possible that René undergoes a cogitatio, i.e., a formally real mode of thought: a genuine mental modification that is immediately conscious as occurring. What Descartes would deny is the stronger claim that this same item is an idea taken objectively—an idea-or with internally object-fixing content (idea-r-int) that contains a determinate representatum.

Dr. Ring:

Again, what classification, in addition to being an idea-m, would Descartes likely classify the mystery idea under?

ChatGPT 5.2 Thinking:

Yes: Descartes would almost certainly slot it under the class of obscure and confused ideas—and, on that basis, he would regard it as a prime candidate for material falsity (in the technical Cartesian sense).

1) The immediate label: obscure and confused (non–object-fixing). The “mystery idea” is obscure and confused in precisely the sense relevant to his theory of ideas: it fails to determine a representatum internally (no idea-r-int, no idea-or).

2) The further (and sharper) label: materially false (as a “non-thing as thing” case). The episode supplies “matter for error” by inclining the mind to treat what is not determined as if it were determined, i.e., to treat a “non-thing” (no internally specified object) as if it were a thing (an idea with determinate objective content). That is exactly the structural profile Descartes marks out when he introduces material falsity.

Dr. Ring:

Excellent response. However, here is my first hint.

Hint number one: Is the mystery idea a purely intellectual idea or not for Descartes?

ChatGPT 5.2 Thinking:

Not a purely intellectual idea—at least, not in the sense Descartes’s theory of ideas requires for that label to do any epistemic or metaphysical work. The right Cartesian verdict is: it is not a purely intellectual idea (not idea-i), but rather a confused/obscure idea-m that tempts misclassification as intellectual and thus earns the “materially false” label.

Dr. Ring:

Hint number two: If it is not a purely intellectual idea, what other type of idea might it be for Descartes?

ChatGPT 5.2 Thinking:

If Descartes denies that René’s “mystery idea” is a purely intellectual idea (idea-i), the next most likely classification is that it belongs to the sensory/imaginative family, i.e., an idea-s (broadly: a perceptio arising from the mind–body composite). Even if René reports “non-sensory,” Descartes will privilege the functional profile over the self-ascription: indeterminate “ofness,” resistance to analysis, and immediate inclination to objectify are exactly the marks of the obscure and confused perceptions that come from the union. So: not idea-i; instead idea-s (or imagination-adjacent), hence obscure/confused and a natural candidate for material falsity.

Dr. Ring:

Bingo. You got it!

ChatGPT 5.2 Thinking:

Then the full Cartesian classification stack for René’s “mystery idea” is:

• Metaphysical kind: cogitatio / idea-m (a formally real mode of mind).
• Species (against René’s self-description): not idea-i, but idea-s (sensory-family).
• Epistemic status: obscure and confused.
• Error-profile: a prime case of material falsity, because it naturally invites the mind to treat what is not internally object-fixing as if it were idea-or.

Application to the Cold Sensation

Dr. Ring:

Do we not then have an argument and a proof that, in effect, concludes, given how Descartes characterizes his sensation of cold, that such mental states contain no objective reality representations at all?

ChatGPT 5.2 Thinking:

Not a proof in the strict Cartesian sense. What results is a very strong interpretive argument (indeed, the best explanation) that the cold sensation, considered as a first-order sensory mode, contains no internal/object-fixing objective reality, but it is not a demonstrative proof unless one adds further premises.

The argument reconstructed with maximal force

Premise 1: Objective reality requires internally object-fixing content. On Descartes’s official theory, objective reality is the reality an idea has insofar as it presents an object, i.e., insofar as it contains a determinate representatum objectively in the intellect.

Premise 2: Cold sensation is characterized by in-the-moment underdetermination of its “of-what.” The sensory deliverance does not determine whether it is of a privation, a real quality, both, or neither.

Premise 3: Under that characterization, the state is best classified as idea-s, not idea-i.

Conclusion (strong): the cold sensation, taken strictly as the sensory episode, has no objective reality (no internal/object-fixing representational content). It is idea-m but not idea-or.

Why this still is not a strict “proof”

A defender of “minimal OR” has two live escape routes:

• Escape A: “Indeterminate objective content is still objective content”—the cold sensation represents something corporeal, whatever it may be, and that thin “something corporeal” is enough to count as objective content.
• Escape B: “The sensation + implicit natural signification counts as representation”—the sensory state represents a bodily condition by nature’s institution.

To close these, one needs explicit bridging premises: (i) OR requires a determinate internally fixed representatum-type; (ii) signification-by-law is not OR. These are principled reconstructions Descartes does not package as theorems, but they make his system coherent.

The Theodicy Argument (Revised First Reaction)

Dr. Ring (original formulation):

In Descartes’s Third Meditation, where he discusses his sensation of cold, the meditator still does not yet know that anything exists besides himself. So, it could be that no external physical universe exists at all, yet he is still certain he is experiencing a cold sensation. Were his cold sensation to be minimally representing corporeality when no corporeality existed, then God would be a deceiver, which is impossible for Descartes. Therefore, a cold sensation could not ever have even minimally any objective reality representational content of corporeality, right?

ChatGPT 5.2 Thinking:

Not quite, in that crude form. The conclusion you want is still the best Cartesian outcome—but this particular “God-deceiver” argument does not strictly force it. Passivity does not entail compelled assent. Descartes’s standard error theory is that falsity arises when the will outruns the intellect; sensations incline but do not compel. Ideas can be “of” what does not exist without God thereby deceiving. The more Cartesian pressure point is the underdetermination argument, not the deceiver argument.

Dr. Ring (revised first reaction):

I accept your clarifications that (i) passive reception of a sensation does not by itself compel assent, and (ii) Descartes locates error in the will’s over-extension, not in the mere occurrence of the perception. Granting both, my point is not that a “minimal corporeality” OR-content in the cold sensation would logically force the meditator’s judgment. My point is structural, and it runs through Descartes’s own theodicy rather than around it.

Descartes’s divine-veracity guarantee in the Meditations is calibrated precisely: God guarantees the truth of what I clearly and distinctly perceive, and correspondingly God is no deceiver because the faculties He has given me, used properly, do not deliver falsehood at the level where assent is unavoidable. That is exactly why sensations do not get the clear-and-distinct guarantee — and why Descartes, in Meditation VI, has to distinguish the teaching of nature (which concerns the preservation of the mind–body composite) from what the intellect clearly and distinctly perceives about bodies.

Now ask: why must sensations be excluded from the clear-and-distinct guarantee? On the “minimal OR of corporeality” reading, the cold sensation would internally contain, as part of its objective content, the representation of a corporeal cause—even when (at the stage of Meditation III) no corporeal thing is known to exist, and even in the scenario where none exists at all. A faculty whose constitutive deliverances represent corporeal causes as corporeal, independently of whether any such causes obtain, is precisely the kind of faculty whose unreliability the divine-veracity argument needs to quarantine. Descartes’s quarantine strategy is to deny that sensations carry determinate objective content of bodies at all: they incline, they signify externally by nature’s institution, but they do not internally contain a corporeal representatum. That is why assent to their apparent “of-what” is always the meditator’s responsibility and never God’s.

The “minimal OR” reading inverts this structure. It puts determinate corporeal content inside the sensation, and then tries to protect God’s veracity by saying the meditator could always withhold assent. But this makes the divine-veracity argument do work it was never designed to do: it now has to cover faculties whose internal representational deliverances misrepresent, and rely on will-discipline to prevent the misrepresentation from becoming error. That is not Descartes’s theodicy; it is a Malebranchean or occasionalist repair.

So the proper Cartesian form of the argument is not “passive sensation forces assent, therefore God deceives.” It is: Descartes’s way of exonerating God from the unreliability of sensations presupposes that sensations do not carry determinate OR-content of corporeal things. If they did, the quarantine collapses, and the divine-veracity argument would have to be rewritten. Since Descartes does not rewrite it, and since his actual treatment of sensations (obscure, confused, materially false, fit only for the preservation of the composite) is exactly what the no-OR reading predicts, the inference runs: Descartes’s theodicy commits him to denying that the cold sensation has even “minimal” OR of corporeality. That is the corrected form of my first reaction. My second reaction—the underdetermination argument — stands on its own and is the cleaner knockout.

The Underdetermination Argument (Second Reaction)

Dr. Ring:

If a cold sensation is such that one cannot determine whether it is of X, not of X, or neither one, then one also could not determine if that sensation is of corporeality, or not of corporeality, so it cannot even minimally be of corporeality with some minimal OR, correct?

ChatGPT 5.2 Thinking:

This is close to a knockout. The best formulation is: given Descartes’s own way of cashing out objective reality—as a determinate representatum-type contained in the idea—an idea whose deliverance is so underdeterminate that it cannot settle even X/not-X/neither is not the kind of state that can contain OR-content of corporeality. Any “minimal corporeality” would either (i) be too indeterminate to count as OR at all (collapsing into mere causal dependence), or (ii) be determinate enough to count as OR, in which case it contradicts the very characterization of the sensation as leaving the “of-what” unsettled.

That is the decisive point: OR is not a mere “there is some cause out there” placeholder. It is a measure of internally determined content. If you let “minimal OR” be compatible with radical underdetermination, you deflate OR into something that no longer plays its Meditation III role.

Coda: idea-r-int vs. idea-r-ext

The reason “minimal OR” is such a persistent temptation—one that reappears in De Rosa, Wee, and, in a different register, in the model’s first retreat above—is that it trades on an ambiguity in the word representation. Descartes’s theory of ideas requires us to separate two things that ordinary usage runs together:

• idea-r-int — internal representation. The idea internally contains a determinate representatum as its objective content. This is what Descartes means by an idea taken objectively, and this, and only this, is what his doctrine of objective reality measures. An idea with idea-r-int fixes its “of-what” from the inside; that fixing is what gives it the degree of objective reality the causal-adequacy arguments of Meditation III trade on.
• idea-r-ext — external signification. The mental state is correlated, by nature’s institution or by the teleology of the mind–body union, with some bodily condition or environmental feature. The state “points to” or “signifies” that condition in the sense that it was instituted to arise on its occasion and to prompt a preservation-apt response. Nothing about this correlation requires that the state internally contain a determinate representatum of what it signifies. A red light signifies “stop” by convention; it does not thereby contain stopping as its objective content.

The cold sensation, on Descartes’s characterization, has at most idea-r-ext. It arises on the occasion of certain bodily conditions; it is instituted by nature to prompt the composite to withdraw; it “signifies” corporeal circumstances in the external, lawful, teleological sense. It does not internally contain a determinate representatum—that is precisely the force of Descartes’s saying that the meditator cannot tell, from the sensation itself, whether cold is a privation, a real quality, both, or neither. Underdetermination of representatum just is the absence of idea-r-int.

“Minimal OR” is the attempt to keep idea-r-ext and call it OR. But OR is not a measure of lawful correlation; it is a measure of internal containment of a determinate object-type. Idea-r-ext is not a thin species of OR; it is not OR at all. Once that distinction is held firm, the defender of “minimal corporeality OR” faces the dilemma the model itself formulated: either the content is determinate enough to count as OR (in which case the sensation’s underdetermination is falsified), or it is indeterminate enough to preserve the underdetermination (in which case it is idea-r-ext, not OR).

There is no third option. The cold sensation is idea-m with idea-r-ext and no idea-r-int—hence no objective reality, not even minimally. That is the DTOI verdict, and it is the verdict Descartes’s own characterization of the cold case, his theodicy structure, and the material/objective equivocation jointly require.

Conclusion

The dialectical trajectory of this post can be stated compactly. A “purely intellectual” idea whose content is indeterminate at the level of X / not-X / neither is, by Descartes’s own criteria, not a purely intellectual idea. It is an idea taken materially only—a cogitatio, a formally real mode of thought—whose failure to fix any representatum from the inside places it in the sensory/imaginative family, marks it as obscure and confused, and makes it a prime candidate for material falsity. This is the verdict ChatGPT-5.2 Thinking was walked into by the mystery-idea scenario, and it is a verdict the model ratified in Descartes’s own voice.

Applied to the cold sensation—which Descartes explicitly characterizes as underdetermined between privation, real quality, both, or neither—the verdict transfers without remainder. The cold sensation is idea-m, obscure and confused, sensory-family, and materially false in kind. It carries no idea-r-int, no internally object-fixing representational content, and therefore no objective reality. The “minimal OR of corporeality” reading survives only by equivocating between two things Descartes’s theory requires us to keep apart: the internal containment of a determinate representatum (idea-r-int, which alone is what objective reality measures) and the external signification of a bodily condition by nature’s institution (idea-r-ext, which is lawful correlation and teleology, not representational content). Once that distinction is made explicit, the defender of minimal OR faces an exclusive and exhaustive disjunction: either the sensation’s content is determinate enough to count as OR, in which case Descartes’s characterization of cold as radically underdetermined is falsified; or the content is indeterminate enough to preserve that characterization, in which case it is idea-r-ext and not OR at all. There is no third option.

The God-deceiver argument, in its cruder form, does not strictly force this result, and I have granted as much. Descartes’s error theory locates falsity in the will’s assent, not in the mere occurrence of a passive sensation, and that locates a genuine gap between “passive reception” and “compelled judgment.” But the corrected form of the theodicy argument — presented in the revised first reaction above—reaches the same conclusion by a different route. Descartes’s divine-veracity strategy exonerates God from the unreliability of sensations precisely because sensations do not carry determinate internal OR-content of bodies; if they did, the quarantine collapses and the theodicy would have to be rewritten. Since Descartes does not rewrite it, and since his actual treatment of sensations (obscure, confused, fit only for preserving the composite, liable to material falsity) is exactly what the no-OR reading predicts, his theodicy is itself evidence for the no-OR verdict rather than a separate argument to it.

The broader moral for DTOI is that objective reality is not a causal-dependence placeholder and cannot be cheapened into one. It is a determinacy measure: a measure of what an idea internally contains as its representatum, ranked by the ontological grade of that representatum-type. Ideas that do not internally fix a representatum—sensations first among them, but also the mystery-idea scenario, the idea of nothing, and (on the reading I defend elsewhere) common notions—fall outside the OR framework altogether. They are not ideas with vanishingly small OR; they are ideas to which the OR measure simply does not apply. The cold sensation is the clearest test case for this thesis, because it is the one Descartes himself chose to illustrate the limits of his representational vocabulary. Read with the material/objective equivocation in hand and with idea-r-int / idea-r-ext held firmly apart, the cold case does not embarrass DTOI. It vindicates it.
