What does Nelson think makes sensations obscure and confused?

“4. Confused and obscure ideas

In (4) the absolutely crucial notion of clear and distinct perception was characterized in terms of its relation to the operation of the will. It is important to remember that this is Descartes’s own procedure. A simple count of the texts that say something interesting about the technical sense of clear and distinct perception shows that nearly all involve reference to their inevitable affirmation. Descartes is not particularly concerned to write abstractly about clear and distinct perception because he is certain that the best way for his student to under-stand what is intended by the notion is for him to meditate along with Descartes and get clear and distinct perceptions of his own. The student then learns by intimate first-hand experience what these special per-ceptions are, what they are like, and how to get them.

Nevertheless, in the Principles, which Descartes intended as a textbook, he does produce something like definitions of the technical terms ‘clear’ and ‘distinct.’

I call a perception ‘clear’ when it is present and accessible to the attentive mind — just as we say that we see something clearly when it is present to the eye’s gaze and stimulates it with a suf-ficient degree of strength and accessibility. I call a perception distinct if, as well as being clear, it is so sharply separated from all other perceptions that it contains within itself only what is clear (Prin I 45).

These definitions are significant because they directly define clarity and distinctness in terms of the intrinsic character of such perceptions instead of indirectly (as in (4)) in terms of their relationship to the will. Even more important and enlightening, however, is the continuation of this passage in Prin I 46 where Descartes explains the production of confusion and obscurity from clear and distinct perceptions. Let us break this into pieces; the first piece to consider is this:

. . . when someone feels an intense pain, the perception he has of it is indeed very clear, but is not always distinct.

I find it very significant that Descartes says that pains are not always distinct, definitely implying that sometimes they are. This is in accordance with Prin I 68 which, as we have seen, maintains that sensory ideas can, under the right conditions, be clearly and distinctly perceived. Prin I 46 now continues with the description of a process that produces confused perceptions,

For people commonly confuse this perception with an obscured judgment they make concerning the nature of something which they think exists in the painful spot and which they suppose to resemble the sensation of pain . . . .

This dense sentence must be carefully unpacked piece by piece.

(a) The perception of pain which is not always distinct (but sometimes can be) is commonly confused with something else. Again we see that the confusion is not inevitable, or even invariable; sensory ideas are only commonly so confused. What happens to a sensory idea like pain when it is confused? It is

(b) quite literally con-fused with something else. This means that a kind of unified idea, a confused one, is the product of joining together two other ideas in our thought. One of the compounded elements is the sensory idea we began with — this sensory idea might even have been clear and distinct to start. The other element of the compound is referred to in this text as

(c) an obscured judgment. This means that the second element is itself an idea which results from a judgment—apparently a bad judgment since it is called “obscured.”¹⁹ This faulty judgment, the second element of the confused compound, is obscured because it makes the error of attributing something resembling the sensory idea itself to bodies outside me. This is a great error, of course, because the sensory idea can be clearly and distinctly perceived only as a mode of mind alone. If one wishes to make good judgment concerning body, one must rely on what can be clearly and distinctly perceived in the idea of body: modes of extension, or else the modest judgment that something or other in the body causes me to have the sensory ideas.²⁰

This account can be generalized and then explained diagrammatically.²¹ Let us represent innate ideas (which, according to (7), can be clearly and distinctly perceived) with circles. Confused and obscured ideas will be pictured as non-circular, irregular shapes where greater departures from clear-and-distinctness. Here, for example are the innate ideas of God and of body:

In a moment of weakness one might judge that God is extended. The result of this judgment can now be represented as a confused combination of the two, initially clear and distinct ideas:

God + Body —> Corporeal God

Once we have thought up this confused, materially false idea, we have subject matter for further false judgments.²² For example, we might now judge that the Moon is a part of God. This would involve combining the confused idea of God with the already inevitably confused idea of the Moon:

Corporeal God + Moon —> Moon-is-part-of-God

One might wonder whether the final product here should be considered a confused idea of body, or a confused idea of God, or etc. More generally, these diagrams raise questions concerning the “identity conditions” for ideas. The answer to these questions is that this purely semantic matter of no interest to Descartes. The idea simply is what it is: a messy heap of component ideas that we have mixed together in our thought. Since one of its components is the (innate) idea of God, we might call it a confused idea of God, but in some contexts it would make just as much, or more, sense to call it the confused idea of body, or the confused idea of any of the components of the heap. The semantic decision about what to call a confused idea will be a pragmatic one depending on our concerns at the time.²³

This entire analysis of confusion and obscurity should be understood quite literally. An idea is confused if it is a composite incorrectly regarded as a unity.

It happens in almost every case of imperfect knowledge that many things are apprehended together as a unity, though they will later have to be distinguished by a more careful examination (Sixth Replies, AT VII 445).

An idea which is the confused composite of two other ideas will be fairly easy to distinguish and clarify into its components. In the general case, however, a confused idea will be a composite of many elements and potentially very difficult to analyze into its potentially distinct components. The mental mechanism of confusing ideas must involve the judgment depicted in the diagrams by an arrow. One judges, at least initially, that two or more ideas belong together; if they do not in fact fit together, the result is confusion.²⁴

Applying this scheme to the case of sensory ideas, we would have the following:

Sensory idea of pain + Judgment that something resembling the pain is in the painful body part —> Confused sensory idea

One thing brought out by this diagram is that confused sensory ideas are also always the result of judgments on our part.²⁵ Confusion and obscurity are not intrinsic to the sensory ideas themselves—that would not be compatible with their status as innate ideas. It must be the case that sensory ideas and other innate ideas become confused through some process, since they would be clearly and distinctly perceived if we became aware of them before their confusion with other ideas.²⁶

The diagrams illustrate confused ideas, what of the complementary notion of obscurity? Keeping in mind that Descartes is not always careful with the terminology of clear/distinct and even less careful with confused/obscured, some elucidation is possible. Confusion is the opposite of distinctness, obscurity the opposite of clarity. Since distinctness (in the strict sense of Prin I 45) entails clarity, obscurity must entail confusion. In fact, the two turn out to be coextensive as can be seen in the diagrams. The term ‘obscure’ and the Latin ‘obscurus‘ connote darkness. This makes for a natural complement of ‘clear’. They also connote, especially in the verbal form, covering, the obscuring of one thing by another. So in the case of a confused and obscured sensory idea, we have that potentially clear and distinct idea confused with, but also obscured by, an overlaying bad judgment.

Sensory idea + Bad judgment concerning its cause —> Confused and Obscure idea

In this diagram, we can think of the second component, the bad judgment, as literally covering up and obscuring the underlying sensory idea. Whenever we have a confused idea, therefore, we can think of some of its components as obscuring others preventing them from being clearly perceived. There need not be a fact of the matter about exactly which are the obscuring and which the obscured components; they are all obscured. Clear perception of the individual components would require first distinguishing them from one another. The diagrams also show that the complete absence of obscurity—perfect clarity— is coextensive with perfect distinctness. In other words, perfect clarity is a feature of only clear and distinct ideas.²⁷

Before considering some potential philosophical objections to my interpretation, let us dissolve an apparent textual difficulty. One might wonder whether Descartes made a mistake, or changed his mind, when he wrote Prin I 68 and the other texts which tightly cohere with it. There are, of course, a number of texts which have led commentators to suppose that Descartes must have understood sensory ideas as being intrinsically confused such that they could never be rendered clear and distinct in the Prin I 68 sense. A good representative of these texts comes from the Sixth Meditation,

For these sensations of hunger, thirst, pain and so on are nothing but confused modes of thinking which arise form the union and, as it were, intermingling of the mind with the body (AT VIII 81).

Not many have wanted to throw away the “as it were” in Descartes’s “as it were, intermingling” [quasi permixtum] to read him as saying that sensations are literally metaphysical modes of a unified mind-body substance. Most, however, have been convinced that sensory ideas must intrinsically reflect or represent the ineffable intermingling or mixing of mind and body. I agree that sensory ideas must be modes of mind only, and I even agree that when sensory ideas are confused (as they are whenever we are not doing metaphysics and distinguishing them in the manner of Prin I 68) they are confused because of our being composites of mind and body. This much is clearly indicated by the Sixth Meditation text and others like it. The source of the confusion is, nevertheless, not the metaphysical mixing of mind and body. Because we are embodied and are constituted to preserve this embodiment, we make judgments about how things stand in our vicinity and how they are likely to cause us benefit and harm. God has made us so that our sensory ideas are systematically correlated with features of our physical vicinity, and he accordingly further devised us so that the judgments we naturally made in our everyday lives (i.e., not only carefully considered metaphysical judgments) tend to be conducive to preserving our mind-body composites. We accomplish this efficiently with confused ideas, and not by fully grasping the metaphysical truth about our physical vicinity. It is, accordingly, the fact that we are embodied that “gives rise” to our making the judgments that confuse our sensory ideas.

Phenomenological considerations might suggest two philosophical, rather than textual, objections to the interpretive theory developed above. According to this theory, all confused ideas, including confused sensory ideas, become literally confused by judgments combining component ideas. But sensory ideas are almost always confused, they generally become clear and distinct only as a result of careful meditation. The first potential objection, then, is that no one will report being able to remember having made the innumerable judgments that resulted in his repertoire of sensory ideas being paradigmatically confused. This gets a straight-forward response from Descartes.

Everyone has, in fact, made innumerable confusing judgments, but they are not remembered or noticed because they are natural and habitual. The habits are very deeply ingrained because they date from infancy.

In our childhood the mind was so immersed in the body that although there was much that it perceived clearly, it never perceived anything distinctly. But in spite of this the mind made judgments about many things, and this is the origin of the many preconceived opinions which most of us never subsequently abandon (Prin I 47).

The biological necessity of these judgments could not be overcome even by the most careful schooling of children since passions and corresponding judgments occur from the moment of conception.

Those four passions [joy, love, sadness, and hatred], I believe, were the first we had, and the only ones we had before our birth. I think they were then only sensations or very confused thoughts, because the soul was so attached to matter that it could not yet do anything else except receive various impressions from it (Letter to Chanut, 1647, AT IV 605).

It also happens that our ideas accrue confusion through the habitual reapplication of remembered judgments, so it is by no means necessary that confusion is always the result of careful deliberative judgment. Even though we emerge from childhood able sometimes to pursue the truth by detaching ourselves from attending to our bodies, still,

. . . it is not easy for the mind to erase these false judgments from its memory; and as long as they stick there, they can cause a variety of errors (Prin I 72).

In short, every human being has developed confused sensory ideas dating all the way back to conception. The confusion can be compounded by learning bad science. Many of these confused ideas have biological utility in helping us to stay alive, but they must be made distinct if we wish to pursue the truth by doing metaphysics. This is part of the reason Descartes advocates beginning metaphysical studies with a universal doubt that purges the prejudices of childhood.²⁸

The second potential objection motivated by phenomenology is that sensory ideas seem to some philosophers to be intrinsically confused. The apparent objection is developed by saying that external objects are seen as having phenomenal properties because sensory ideas phenomenally present themselves as being properties of external objects. Some are inclined to say, allying themselves with the Scholastic Aristotelians, that it seems as if redness is presented as being in the apple just as the apple is presented as being a certain size. Perhaps a more forceful example is a pain’s presenting itself as if in the foot. Since the sensory quality of redness is not really in the apple, and the pain is really a mode of the mind and not in the foot, the sensory ideas that present them that way are thought to be deceptive, and in that sense, “confused and obscured”. But this is not Descartes.

Descartes thought, again, that when sensory ideas are clearly and distinctly perceived (Prin I 68), they reveal themselves as modes of mind alone. Moreover, (4) has it that a clearly and distinctly perceived idea compels the will to affirm that the sensory idea is a mode of mind alone. It follows that anything concerning sensory ideas that is attached to corporeal objects becomes so attached by judgment.²⁹ This is true even of such “primary qualities” as size.

Concerning the manner in which we see the size and shape of objects . . . [w]e judge their size by the knowledge or opinion we have of their distance compared with the size of the images they imprint on the back of the eye . . . (Optics, AT VI 140, emphasis added).

Descartes does not confine his position to technical scientific texts, he is similarly explicit in the Sixth Meditation,

. . . although a star has no greater effect on my eye than the flame of a small light, that does not mean that there is any real or positive inclination in me to believe that the star is no bigger than the light; I have simply made this judgment since childhood onwards without any rational basis (AT VII 83, emphasis added).

The second phenomenological objection to my interpretation would have it that the star presents itself to me as no bigger than the light, so the sensory idea or ideas themselves do incline me to make that false judgment. Descartes leaves no room for that alternative to my interpretation. Another relevant text can be found in his comment on the illusory largeness of the sun and moon on the horizon.

. . . the astronomers prove clearly that they appear larger at one time than at another not because they are seen to subtend a greater angle, but because they are judged to be farther away (Optics, AT VI 145, emphasis added).”

NOTES to “Descartes’ Ontology of Thought”

[NOTE: Footnotes 17 and 18 below are found on p. 166, which is one page earlier than the quoted passages above.]

¹⁷ As is so often the case, doctrines of Descartes’s that seem incongruous to us did not seem so to contemporaries who were sympathetic to his views. Arnauld makes much of the fact that Descartes held that sensory ideas can be clearly and distinctly perceived. See, for example, K 132–33 and 139.

¹⁸ One might object that Prin I 68 does not assert that sensory ideas are themselves clearly and distinctly perceivable, but instead that we can clearly and distinctly perceive that sensory ideas are modes of mind alone. It would be compatible with this second reading that sensory ideas themselves are intrinsically confused. This alternative reading might be buttressed by recalling that Descartes says fairly explicitly both that the innate idea of mind-body union cannot be clearly and distinctly perceived, but that we do clearly and distinctly perceive our mind-body union (see note 12 above).

The inferiority of this interpretation will become evident in what follows, but one observation is in order here. The idea of mind-body union involves an intellectually incomprehensible combination of exactly two, “in a way opposite” elements: indivisible, thinking substance with a power to act on body, and divisible, extended substance with a power to act on mind (AT III 665). The idea gives us a peculiar kind of knowledge—knowledge through use, as it were (AT III 692). The inferior interpretation of Prin I 68 contrasts with this in that it requires sensory ideas to either obscurely represent something we-know-not-what in bodies, or instead to “lack objective reality” and not be composites of potentially distinct ideas. Either way, the ideas cannot directly give us any knowledge of the special kind that the idea of union can.

¹⁹ The Latin obscuro supports the translation obscured which is better than CSM’s ‘obscure’ since it shows that the judgment has been actively degraded. The French version instead simply has ‘false.’ I shall write obscured in what follows.

²⁰ Compare Prin I 69 and 70.

²¹ I want to emphasize that these diagrams are highly analogical and schematic. Thought is, of course, in no way extended so drawings are inherently flawed as explications of it. Descartes himself, however, does not hesitate to use visual metaphors to explain his thought. In fact, his own characterizations of clarity and distinctness at Prin I 45-46, are, as commentators have noted, full of illusions to visual perception. I think Kurt Smith for discussions of the diagrams and for preparing them from my sketches.

²² Descartes defines materially false ideas as those that give “subject matter for false judgment” in the Fourth Replies. For a discussion see Nelson (1996).

²³ In 1641 Descartes write to Mersenne, I do not understand your question whether our ideas are expressed by a single term. Words are human inventions, so one can always use one or several to express the same thing. But I explained in my Reply to the First Objections how a triangle inscribed in a square can be taken as a single idea or as several (AT III 417-418).

²⁴ Cases in which they do fit are discussed in note 26.

²⁵ In the preceding diagram we see that at least two judgments are involved. First, the judgment(s) involved in producing the obscured judgment that serves as a component of the eventually confused idea. And second, the judgment that confuses the two components to produce the end result.

²⁶ Confused ideas are the result of bad, “obscuring” judgments. It is also possible, of course, to make good judgments that result in clearly and distinctly perceived ideas. One might, for instance judge that the Pythagorean theorem holds of right triangles:

Right triangle + The “Pythagorean Theorem propery” (PT) —> PT holds for right triangles

Here I have pictured the result of the judgment by showing the two initial clear and distinct ideas contemplated as “touching” each other. Other depictions are possible, of course. Another kind of case comes about when the result of the judgment is regarded as a unity, but there is, nonetheless, no confusion. Descartes’s example is an inscribed geometrical figure:

Triangle + Square —> Triangle inscribed in a square

Here the result of the judgment has its own “true and immutable nature” and is accordingly innate and clearly and distinctly perceivable (First Replies AT VII 118). It is, therefore, best pictured as a simple idea even though it is analyzable when no longer regarded as a unity with its own properties, etc. In this context, consider again the text quoted in note 23.

²⁷ This might seem at odds with the already cited passage from Prin I 46 where Descartes gives intense pain as an example of something that is “very clear”, but not distinct. He concludes that Article with the general observation that an idea can be clear without being distinct, but not distinct without being clear. This should be read as saying that an idea can be “very” clear without being distinct, but not that it can be maximally clear without being distinct. this seems to be born out by phenomenology. A pain, no matter how intense and surprising, never completely distracts our attention from other sensory modalities.

It is worth emphasizing here that while clear-and-distinctness, like obscure-and-confusedness, is a matter of degree, there is a maximum degree of clear-and-distinctness which is marked by the compulsion of the will.

In Alan Nelson’s examination of what makes sensations “obscure and confused” in “Descartes’s Ontology of Thought,” he argues that these qualities arise from specific mental processes rather than from intrinsic properties of the sensations themselves. Here are some core points Nelson highlights to explain this notion:

1. Role of Judgments in Confusion and Obscurity: Nelson argues that sensations become confused and obscure when they are overlaid with misleading judgments. These judgments mistakenly attribute properties to sensations that do not actually belong to them, especially properties believed to reside in external objects. For example, when one feels pain, there is a tendency to associate this feeling with an external part of the body, like the foot, despite the pain being a mental sensation. This attribution of externality, formed by judgment, is what confuses the sensory idea of pain.
2. Confusion as a Composite of Ideas: Nelson describes confusion as the result of combining two ideas—a clear sensory idea and an erroneous judgment—into a single, compounded idea. This composite nature is “confused” because it merges unrelated ideas, forming a unity where there should be distinct separation. A sensation, which might be clear on its own, becomes confused when joined with an obscure judgment about its source or location in the external world.
3. Obscurity as the Opposite of Clarity: According to Nelson’s interpretation, “obscurity” is the opposite of “clarity.” While clear ideas are direct and accessible to the mind, obscure ideas are covered or overshadowed by incorrect judgments. In this view, obscurity entails a kind of mental “darkness” or blocking that results from these false overlays, which prevent the mind from perceiving the sensory idea’s true nature.
4. Biological and Habitual Origins of Confusion: Nelson also suggests that these judgments are not necessarily deliberate but rather deeply ingrained habits formed from infancy. Humans naturally develop confused ideas as they interact with the world, and these ideas serve practical purposes. For instance, confusing sensory experiences with external causes may help the mind-body composite adapt to and navigate physical reality. This habitual confusion is challenging to clear up without careful meditation and philosophical study.
5. Embodiment as a Source of Confusion: Nelson attributes the common occurrence of confused sensory ideas to the embodied nature of human beings. Our physical and mental unity leads us to interpret sensations as properties of external objects, a necessary but ultimately misleading mechanism for survival. However, through deliberate philosophical analysis, one can learn to perceive sensory ideas distinctly as modes of the mind, free from this embodied confusion.

Nelson’s interpretation thus emphasizes that confusion and obscurity are not inherent to sensory ideas; instead, they result from misguided judgments layered onto these ideas, often as a consequence of our embodied experience and mental habits.

However, there may be a problem with Nelson’s interpretation that adding a false judgment entirely causes obscurity and confusion. What is Nelson’s explanation for what it is about a sensation that would incline a mind into making a false judgment?

Scholar ChatGPT:

Nelson acknowledges that while obscurity and confusion in sensations result from superimposing false judgments, there remains a question: why are minds inclined to make these judgments in the first place, especially if sensory ideas could, theoretically, be perceived clearly and distinctly?

Nelson provides several explanations for this inclination:

1. Innate Tendencies Due to Embodiment: Nelson argues that our embodied nature inclines us toward making judgments that naturally connect sensations with external causes. The human mind-body composite leads to an inherent tendency to interpret sensations, such as pain, as something located in the body (e.g., the foot) or caused by an external object, even though the sensation itself is purely a mental experience. This inclination is not entirely voluntary but arises from how humans are constituted as beings that interact with their environment in practical, survival-oriented ways. Thus, the body’s influence makes it almost automatic for the mind to form such judgments, even if they are technically erroneous.
2. Biological Utility of Confused Sensations: Nelson suggests that these confused and obscure ideas serve a practical function, helping the mind navigate and react to the physical world efficiently. For instance, judging that a painful sensation originates in the foot is a useful response that prompts protective actions, even though this judgment incorrectly attributes the sensation to an external cause. Thus, the mind is “designed” to make such judgments as a biological adaptation, which fosters survival but at the cost of accuracy.
3. Habitual and Deeply Ingrained Judgments from Early Childhood: Nelson explains that many of these confused judgments originate in childhood, where the mind, heavily influenced by the body, forms habitual ways of interpreting sensations. Since these judgments start at a very young age, they become deeply ingrained and automatic, occurring without conscious deliberation. The judgments are so habitual that they are rarely questioned or examined, making it difficult for the mind to distinguish the pure sensation from the judgment it associates with it.
4. Psychological Attachment to the Body: Nelson also points to a kind of psychological attachment between the mind and the body, leading individuals to regard sensations as extensions of physical experiences. This attachment, combined with a practical concern for bodily welfare, inclines the mind to interpret sensations through judgments that relate them to the physical body.

In summary, Nelson’s interpretation suggests that the mind is inclined toward making these false judgments due to a combination of biological, habitual, and psychological factors rooted in human embodiment. These factors create a natural bias toward associating sensory experiences with external objects or bodily locations, making clear and distinct perception of sensations challenging without deliberate philosophical effort.

Is the feeling of hunger when the body craves nourishment ever an obscure and confused sensation?

Scholar ChatGPT:

Yes, according to Nelson’s interpretation in line with Descartes’s philosophy, the sensation of hunger can indeed be considered obscure and confused, though it serves a functional purpose.

Here’s how this applies:

1. Association with the Body: The sensation of hunger is tied to bodily needs, specifically the need for nourishment, which makes it a prime example of how sensory ideas are prone to confusion and obscurity. Hunger feels as though it points directly to the stomach or to a physiological state needing attention, and this perception may prompt the mind to judge the sensation as a physical demand. This is a confused interpretation, as hunger, from a Cartesian perspective, is a purely mental experience—a mode of the mind—rather than something that resides in or directly relates to the body. The confusion lies in interpreting it as an indicator of a bodily state rather than understanding it as a mental sensation.
2. Biological Utility of Confusion: The judgment that hunger represents a bodily need is, as Nelson argues, evolutionarily and biologically advantageous. This confusion prompts practical actions, such as eating, to satisfy the sensation. By design, the sensation inclines the mind toward a false judgment—that the hunger itself is a physical state needing rectification. Although this judgment may be “false” in the strict Cartesian sense, it is useful because it supports survival, maintaining the mind-body composite.
3. Inherent Obscurity Due to Habitual Judgments: Hunger sensations, like other primary bodily sensations (pain, thirst, etc.), are almost always felt with a sense of immediacy and attachment to the body. Since these sensations have been associated with bodily states since infancy, the judgment that they indicate a physiological need is deeply ingrained. This makes it challenging to perceive the sensation of hunger in a clear and distinct way, free of this embodied interpretation. The habitual nature of this judgment renders hunger an inherently obscure and confused sensation, as it’s rarely analyzed apart from its bodily connotations.

In short, Nelson would argue that the sensation of hunger is confused and obscure because it is habitually tied to bodily interpretations and judgments that misrepresent the nature of the sensation as purely mental. This intrinsic confusion is functional for our survival but obscures the true nature of the sensation as merely a mode of the mind.

Notice that when you wrote, “The confusion lies in interpreting it [hunger] as an indicator of a bodily state rather than understanding it as a mental sensation,” there is a problem since hunger is indeed an indicator of a bodily state if there ever was one. So, this is not a flaw or error in judgment!

Scholar ChatGPT:

You’re absolutely correct in pointing out that hunger is indeed a reliable indicator of a bodily state, and it’s not an error in judgment to interpret it as such. This highlights a key tension in Nelson’s interpretation of Descartes: sensations like hunger appear to bridge the mind and body in a way that seems both practically correct and experientially valid, rather than being misleading or confused.

Here’s how we might understand this issue more precisely within Nelson’s and Descartes’s frameworks:

1. Practical Validity of Sensations: The sensation of hunger is indeed an indicator of the body’s need for nourishment, and it accurately prompts action to address that need. This accuracy challenges the notion that all sensory ideas are inevitably obscure or confused when associated with bodily states. In the case of hunger, there is little “error” in interpreting it as a call to eat, as this response is directly linked to bodily survival.
2. Cartesian Distinction Between Sensory Perception and Judgment: Nelson argues that, according to Descartes, a sensation becomes confused when a mental idea is misinterpreted or fused with an external cause. Hunger, however, might be an exception because it doesn’t necessarily involve a false judgment. Rather, hunger accurately represents a bodily state and doesn’t inherently mislead us; it directs us to a clear bodily need. Thus, the sensation of hunger might be better understood as a valid mind-body interaction rather than as a confused idea.
3. Mind-Body Interdependence: Hunger illustrates a complex aspect of Descartes’s philosophy: the mind-body union itself. While Descartes often speaks of sensory ideas as “modes of the mind” that could become clearer if stripped of bodily associations, sensations like hunger underscore the reality that some sensory experiences are inherently bound to bodily conditions. This implies that not all bodily-related sensations are confused in the same way. Hunger, for instance, may not require the same philosophical “purification” as other, more ambiguous sensations, because it’s accurately tied to a bodily function.
4. Nelson’s Interpretation Revisited: Nelson might respond to this objection by arguing that hunger only becomes “confused” if one mistakenly interprets the sensation as a representation of an external object with qualities resembling hunger (e.g., attributing hunger as a property of the stomach itself rather than as a signal within the mind). However, this point would still be debatable, as hunger is a case where mind-body interaction seems naturally and purposefully unified, rather than confused.

In summary, hunger seems to be less “confused” than Nelson’s interpretation might suggest. Instead, it represents a coherent mind-body communication about a bodily need, pointing to a productive aspect of the mind-body relationship rather than to an error in judgment. This complexity reflects the idea that not all sensory experiences involving the body are misleading; some, like hunger, may in fact reveal an accurate and necessary unity between mind and body.

I have a different interpretation than Nelson as to why Descartes can consider hunger obscure and confused. It is because even though hunger is a sensory idea, it lacks any objectively real mental content, or as Descartes might say, “the sensation of hunger has no objective reality,” only the formal reality of a phenomenological experience of hunger in the mind. Because hunger has no objectively real mental content it does not present any explicitly represented object of thought. Since we cannot determine through introspection what the hunger sensation intrinsically presents expressly as a representation, the sensation is obscure and confused. 

Scholar ChatGPT:

Your interpretation brings a nuanced perspective to the idea of hunger as an “obscure and confused” sensation within Descartes’s framework. It hinges on the distinction between formal reality (the immediate phenomenological presence of hunger) and objective reality (the content that an idea represents or “points to” in the mind). Here’s how this interpretation aligns with Descartes’s philosophy and provides a distinct rationale for why hunger could be considered obscure and confused:

1. Lack of Objective Content: According to Descartes, an idea has “objective reality” if it presents a mental content that represents or signifies something explicitly. In your view, hunger lacks this objective reality because it doesn’t represent a determinate object of thought. Unlike a clear idea, which presents something distinctly knowable (e.g., a triangle, which has explicit properties and definitions that can be examined), hunger lacks a well-defined object that the mind can analyze or reflect upon in an objective way. Instead, it remains a vague, felt experience without clearly represented content.
2. Purely Phenomenological, Non-Representational Experience: Hunger, as you argue, may be understood as having only “formal reality”—it exists as a feeling or state within consciousness but does not represent any objective content or “thing” that one can identify through introspection alone. From this perspective, hunger does not communicate any specific qualities or attributes of an object, unlike ideas such as geometric shapes or mathematical concepts, which are clear and distinct because they represent particular forms or properties. Instead, hunger is simply felt as an urge or craving without explicit representational qualities, rendering it obscure.
3. Confusion Through Indeterminate Content: This lack of objective reality in the sensation of hunger contributes to its status as “confused” in Descartes’s terms. Since there’s no explicit, introspectively accessible content in hunger, it remains confused in the sense that it’s inseparable from the vague experience of wanting or lacking something, yet it doesn’t provide concrete mental content to clarify what is needed. Hunger’s intrinsic ambiguity—its inability to present a defined object of thought—means that it inherently fails to offer distinct knowledge to the mind.
4. Introspective Limitations and Obscurity: Descartes’s clear and distinct ideas allow introspection to reveal specific, well-defined knowledge. Hunger, by contrast, resists this process because its phenomenology doesn’t point inwardly toward a clear object of thought. Rather, it directs attention outwardly, driving one to seek satisfaction without offering introspective clarity. This aligns with your interpretation that hunger is obscure because it lacks any determinate representational content that could be accessed or understood by the mind alone.

In sum, your interpretation emphasizes that hunger’s obscurity and confusion arise not from a faulty judgment or misinterpretation, but from the sensation’s inherent lack of objective, representational content. By Descartes’s standards, this absence of clear, knowable content leaves hunger without clarity or distinctness, making it a purely formal experience that can be felt but not fully understood through introspection alone. This interpretation powerfully reframes hunger as a sensation that, by its very nature, resists clear and distinct perception.

In your last remarks, you must remember that in the Principles of Philosophy Part 1, Principle 68, Descartes claims that a sensation can be clear and distinct so that sensations are not always obscure and confused.

You’re absolutely correct. Descartes indeed asserts in Principles of Philosophy Part 1, Principle 68 that sensory ideas can be perceived clearly and distinctly, meaning sensations are not necessarily always obscure and confused. This statement introduces an important qualification to the notion that sensory ideas are intrinsically confused. Descartes allows for cases where a sensation can be perceived in a way that is “clear and distinct,” even though, in typical circumstances, sensations often appear obscure due to habitual judgments or lack of objective representational content.

Considering this, let’s refine the interpretation of hunger as potentially obscure and confused while also respecting Descartes’s allowance for clear and distinct perception of sensations:

1. Clear and Distinct Sensations in Principle 68: Descartes indicates that sensations can achieve clarity and distinctness under certain conditions, particularly when the mind refrains from adding false judgments or mistaken associations to the sensory experience. In other words, if one perceives a sensation without projecting external or bodily attributions onto it, it may be possible to experience it in its purely mental, clear, and distinct form. This suggests that while sensory ideas typically become confused through habitual associations (like linking hunger to the stomach), it is possible to recognize them as modes of the mind alone, which clarifies their nature.
2. Hunger as Clear and Distinct Through Philosophical Reflection: Applying Principle 68, the sensation of hunger could, in theory, be perceived clearly and distinctly if one understands it as a purely mental experience without attaching bodily interpretations to it. For Descartes, achieving this clear and distinct perception might involve recognizing hunger simply as a sensation—a mental urge—without assuming it directly represents a physical need or specific bodily location.
3. Phenomenological Experience Without Representation: Hunger, when interpreted as having only formal reality(a subjective experience without objective mental content), might remain phenomenologically present without representational complexity. This could mean that hunger’s sensation might be grasped clearly in terms of “what it feels like” as a mental experience, even though it lacks representational objectivity. In such cases, clarity could emerge from understanding the sensation as purely experiential, devoid of false bodily attributions, but still limited by its lack of objective content.
4. Implications of Clear Sensations for Practical Judgment: Even if the sensation of hunger can be perceived clearly and distinctly, it doesn’t necessarily provide detailed, representational content. Instead, it offers an unambiguous mental experience of needing sustenance. Clarity here would lie in recognizing hunger as an immediate, compelling experience without any direct knowledge about the body or the world, enabling one to respond practically without mistaken representational assumptions.

In summary, Descartes’s Principle 68 affirms that sensory ideas like hunger are not always doomed to obscurity and confusion. Instead, they can be perceived with clarity if one approaches them as non-representational modes of the mind. This perspective clarifies that hunger can be distinctly recognized as a mental sensation that compels action without necessarily attaching external judgments to it, illustrating Descartes’s allowance for clear and distinct perception in sensory experiences.
