Propositionality

It is a great pleasure and an honor to “skywrite” with Vili CsĂĄnyi. I already knew something about how perceptive, sensitive and intelligent dogs were from my years with my beloved LĂ©dike (1959-1975), never forgotten and never “replaced”. But for decades now, starting already from the era of Vili’s unforgettable Bukfenc (and Zebulon, not a dog), both of whom I knew, Vili’s remarkable perceptiveness and understanding of dogs’ cognition and character have soared far beyond my modest mind-reading skill. I have learned so much from Vili that has stayed with me ever since. 

So let me preface this by saying that every example Vili cites below is familiar, valid, and true — but not propositional (though “associative” is a non-explanatory weasel-word to describe what dogs really do perceive, understand, express, want and know, and I regret having evoked it: it explains nothing). 

Dogs, of course, knowingly perceive and understand and can request and show and alert and inform and even teach — their conspecifics as well as humans. But they cannot tell. Because to tell requires language, which means the ability to understand as well as to produce re-combinatory subject/predicate propositions with truth values. (A mirror production/comprehension capacity.) And to be able to do this with one proposition is to be able to do it with all propositions.

When Vili correctly mind-reads Bukfenc, and even mind-reads and describes what Bukfenc is mind-reading about us, and is trying to express to us, Vili is perceiving and explaining far better what dogs are thinking and feeling than most human mortals can. But there is one thing that no neurotypical human can inhibit themselves from doing (except blinkered behaviorists, who mechanically inhibit far, far too much), and that is to “narratize” what the dog perceives, knows, and wants — i.e., to describe it in words, as subject/predicate propositions.

It’s not our fault. Our brains are the products of about 3 million years of human evolution, but especially of language-specific evolution occuring about 300,000 years ago. We evolved a language-biased brain. Not only can we perceive a state of affairs (as many other species can, and do), but we also irresistibly narratize it: we describe it propositionally, in words (like subtitling a silent film, or putting a thought-bubble on an animal cartoon). This is fine when we are observing and explaining physical, chemical, mechanical, and even most biological states of affairs, because we are not implying that the falling apple is thinking “I am being attracted by gravity” or the car is thinking “my engine is overheating.” The apple is being pulled to earth by the force of gravity. The description, the proposition, the narrative, is mine, not the apple’s or the earth’s. Apples and the earth and cars don’t think, let alone think in words) Animals do think. But the interpretation of their thoughts as propositions is in our heads, not theirs.

Mammals and birds do think. And just as we cannot resist narratizing what they are doing (“the rabbit wants to escape from the predator”), which is a proposition, and true, we also cannot resist narratizing what they are thinking (“I want to escape from that predator”), which is a proposition that cannot be literally what the rabbit (or a dog) is thinking, because the rabbit (and any other nonhuman) does not have language: it cannot think any proposition at all, even though what it is doing and what it is wanting can  be described, truly, by us, propositionally, as “the rabbit wants to escape from the predator”). Because if the rabbit could think that propositional thought, it could think (and say, and understand) any proposition, just by re-combinations of content words: subjects and predicates; and it could join in this skywriting discussion with us. That’s what it means to have language capacity — nothing less.

But I am much closer to the insights Vili describes about Bukfenc. I am sure that Vili’s verbal narrative of what Bukfenc is thinking is almost always as exact as the physicist’s narrative about what is happening to the falling apple, and how, and why. But it’s Vili’s narrative, not Bukfenc’s narrative.

I apologize for saying all this with so many propositions. (I’ve explained it all in even more detail with ChatGPT 4o here.)

But now let me answer Vili’s questions directly, and more briefly!):

Bukfenc and Jeromos asked. They then acted on the basis of the reply they got. They often asked who would take them outside, where we were going and the like. The phenomenon was confirmed by MĂĄrta GĂĄcsi with a Belgian shepherd.” IstvĂĄn, do you think that the asking of the proposition (question) is also an association?

My reply to Vili’s first question is: Your narrative correctly describes what Bukfenc and Jeromos wanted, and wanted to know. But B & J can neither say nor think questions nor can they say or think their answers. “Information” is the reduction of uncertainty. So B&J were indeed uncertain about where, when, and with whom they would be going out. The appearance (or the name) of Éva, and the movement toward the door would begin to reduce that uncertainty; and the direction taken (or perhaps the sound of the word “Park”) would reduce it further. But neither that uncertainty, nor its reduction, was linguistic (propositional). 

Let’s not dwell on the vague weasel-word “association.” It means and explains nothing unless one provides a causal mechanism. There were things Bukfenc and Jeromos wanted: to go for a walk, to know who would take them, and where. They cannot ask, because they cannot speak (and not, I hope we agree, because they cannot vocalize). They lack the capacity to formulate a proposition, which, if they had that capacity, would also be the capacity to formulate any proposition (because of the formal and recursive re-combinatory nature of subject/predication), and eventually to discover a way to fly to the moon (or to annihilate the earth). Any proposition can be turned into a question (and vice versa): (P) “We are going out now.” ==> (Q) “We are going out now?” By the same token, it can be turned into a request (or demand): P(1) “We are going out now” ==> (R) “We are going out now!”

My reply is the same for all the other points (which I append in English at the end of this reply). I think you are completely right in your interpretation and description of what each of the dogs wanted, knew, and wanted to know. But that was all about information and uncertainty. It can be described, in words, by us. But it is not a translation of propositions in the dogs’ minds, because there are no propositions in the dogs’ minds.

You closed with: 

“The main problem is that the study of language comprehension in dogs has not even begun. I think that language is a product of culture and that propositions are not born from some kind of grammatical rule, but rather an important learned element of group behavior, which is demonstrated by the fact that it is not only through language that propositions can be expressed, at least in the case of humans.”

I don’t think language is just a cultural invention; I think it is an evolutionary adaptation, with genes and brain modifications that occurred 300,000 years ago, but only in our species. What evolved is what philosophers have dubbed the “propositional attitude” or the disposition to perceive and understand and describe states of affairs in formal subject/predicate terms. It is this disposition that our language-evolved brains are displaying in how we irresistibly describe and conceive nonhuman animal thinking in propositional terms. But propositions are universal, and reciprocal: And propositionality is a mirror-function, with both a productive and receptive aspect. And if you have it for thinking that “the cat is on the mat” you have it, potentially, both comprehensively and productively, for every other potential proposition — all the way up to e = mc2. And that propositional potential is clearly there in every neurotypical human baby that is born with our current genome. The potential expresses itself with minimal need for help from us. But it has never yet emerged from any other species — not even in apes, in the gestural modality, and with a lot of coaxing and training. (I doubt, by the way, that propositionality is merely or mostly a syntactic capacity: it is a semantic capacity if ever there was one.)

There is an alternative possibility, however (and I am pretty sure that I came to this under the influence of Vili): It is possible that propositionality is not a cognitive capacity that our species has and that all other species lack. It could be a motivational disposition, of the kind that induces newborn ducklings to follow and imprint on their mothers. Human children have a compulsion to babble, and imitate speech, and eventually, in the “naming explosion,” to learn the (arbitrary) names of the sensorimotor categories they have already learned. (Deaf children have the same compulsion, but in the gestural modality; oral language has some practical advantages, but gestural language is every bit as propositional as oral language, and has the full power of Katz’s effability.)

Could the genes we have that other species lack be mostly motivational? driving the linguistic curiosity and linguistic compulsion that’s there in human babies and not in baby chimps? (I say “linguistic” c & c, because other species certainly have plenty of sensorimotor c & Cc..)

“When I work upstairs in our house in Almad, Janka lies quietly on the ground floor. When Éva leaves and comes back from somewhere, Janka emits a single characteristic squeal, which can be intended for me, because if I don’t react, she comes up and barks, calling me.” IstvĂĄn, is this a proposition or an association?

“In Almadi, our next-door neighbor came over with his little Bolognese dog named TĂŒcsi, who didn’t come into the garden and stayed waiting at the gate for his owner, with whom we were talking inside the house. Our dog Bukfenc periodically went down to play with TĂŒcsi. After about 10 minutes, Bukfenc came up and turned toward the neighbor and barked at him. Everyone stirred. Bukfenc went straight down the stairs to the gate, followed by the neighbor. TĂŒcsi had disappeared; as it turned out ,he had gone home and Bukfenc was reporting this to the neighbor.” IstvĂĄn, is this a proposition or an association?

“During the time of Bukfenc and Jeromos, I woke up at 3 a.m. to very soft grunting. Bukfenc was grunting very softly and together with Jeromos, they were standing next to my bed. I only opened my eyes a crack, pretending to be asleep. Bukfenc growled softly again, I didn’t react. Jeromos gave a loud squeal. I got up and told them, come on Jeromos, it seems you have something urgent to do. To my surprise, Jeromos went to his bed and lay down, and Bukfenc ran screaming towards the door. He managed to get to the street in time: he had diarrhea.” IstvĂĄn, is Jeromos’s barking a proposition or an association?

Socratic Dialogue with ChatGPT4+ on Cartesian Certainty

SH: Do you remember who I am?

GPT4+: Yes, Professor Harnad, I remember who you are. How can I assist you further today?

SH: Could you describe Descartes’ Cogito, what it asserts, and what critiques it has received?

GPT4+: RenĂ© Descartes’ “Cogito, ergo sum” (“I think, therefore I am”) is a foundational element in modern Western philosophy, introduced in his works “Discourse on the Method” (1637) and “Meditations on First Philosophy” (1641). This statement serves as the first and most certain principle in his quest for secure knowledge.

What the Cogito Asserts

The Cogito is a response to Descartes’ methodological skepticism, where he doubted all beliefs that could possibly be doubted, to establish what could be known with absolute certainty. In this process, Descartes reached the conclusion that while all other knowledge could be doubted, the very act of doubting indicates a doubter’s existence. Thus, if he is thinking, then he must exist. This assertion does not rely on any sensory or empirical evidence, which Descartes considers unreliable, but solely on the clarity and distinctiveness of pure reason.

Critiques of the Cogito

1. Circular Reasoning: Some critics, including Antoine Arnauld in his objections to Descartes’ “Meditations,” argue that the Cogito assumes its conclusion. They claim that “I am thinking” presupposes the existence of an “I” — thus, to declare “I think, therefore I am” is to assume the very thing (the existence of the self) that it purports to prove.

2. Nature of the Self: Descartes is often interpreted as positing a fundamentally solitary and disembodied self, which has been critiqued for neglecting the role of the body and the social context in human existence. Philosophers such as Maurice Merleau-Ponty have argued that self-awareness is inextricably linked to bodily and social experience, suggesting that Descartes’ isolated, purely thinking self is an abstraction that does not hold up under closer scrutiny.

3. Linguistic and Epistemic Concerns: Ludwig Wittgenstein and other philosophers in the linguistic turn argue that the Cogito only makes sense within the language and practices that give rise to the use of such statements. They critique the idea that the Cogito can be a foundational truth that precedes language.

4. Existential and Phenomenological Critiques: Existentialists like SĂžren Kierkegaard and phenomenologists like Edmund Husserl have also provided critiques. Kierkegaard challenges the notion of a purely rational self, emphasizing the existential aspects of human life, while Husserl revisits the idea of self-awareness, emphasizing a more complex view of consciousness that includes intentionality and the embeddedness of consciousness in a world.

5. Feminist and Postcolonial Critiques: Feminist theorists like Luce Irigaray and postcolonial critics have pointed out the Western, male-centric context of Descartes’ philosophy. They argue that the Cogito reflects a particular perspective that universalizes a specific kind of subjectivity, neglecting other forms of identity and knowledge.

Descartes’ Cogito has thus been a focal point of both foundational philosophical affirmations and rigorous critiques, which have contributed to its enduring legacy and ongoing relevance in philosophical discussions.

SH: Let’s just focus on certainty and doubt. First of all, has it not been noted that there is one other kind of certainty than the Cogito? Can we doubt that a formal contradiction (P and not-P) cannot be true?

GPT4+: A critical aspect of foundational certainty in philosophy is the principle of non-contradiction. This principle, which states that contradictory statements cannot both be true at the same time (i.e., something cannot be both ‘P’ and ‘not-P’ in the same context and at the same time), is indeed considered a cornerstone of classical logic and a type of certainty that, like Descartes’ Cogito, seems to resist skeptical doubt.

Principle of Non-Contradiction

Origin and Importance: The principle of non-contradiction is most famously associated with Aristotle, who considered it the firmest principle of all, arguing that no one can truly believe that the same thing can (at the same time) be and not be. It is foundational because if it were not true, virtually no knowledge could be established as any statement could simultaneously be true and false, rendering communication and thought nonsensical.

Relationship to the Cogito

Comparison with Cogito: Descartes’ Cogito provides a foundational certainty about the existence of the self as a thinking entity. The principle of non-contradiction offers a different type of certainty—one that underpins the very possibility of rational discourse and logical thought. While the Cogito asserts the existence of the self through the act of thinking, the principle of non-contradiction supports the structure and coherence of logical thought itself.

Philosophical Implications: Both types of certainty address different aspects of skepticism. Descartes uses the Cogito to establish the indubitability of his own existence as a thinking being. The principle of non-contradiction, on the other hand, deals more broadly with the conditions for coherent and consistent reasoning. Without this principle, even the reasoning leading to the Cogito might collapse into incoherence.

Doubt and Certainty

Doubt of Non-Contradiction? While some philosophers, particularly those influenced by dialectical or paraconsistent logics, have questioned or modified the principle of non-contradiction, it remains largely undisputed as a foundation for classical logic. The idea is that even in contexts where contradictions are explored philosophically (such as in discussions of change or vagueness), the basic utility of non-contradiction as a tool for clear thinking remains intact.

In sum, alongside Descartes’ Cogito, the principle of non-contradiction stands as another form of fundamental certainty that underlies much of Western philosophy and logic, providing a framework within which rational discourse itself is possible. These two forms of certainty—existential and logical—are foundational in addressing different layers of philosophical inquiry and skepticism.

SH: Now the Cogito. “I am thinking therefore I exist”. 

How do I know I am thinking? Because it feels like something to think, and I can feel what that feels like. If I can doubt at all, I can’t doubt that I’m feeling something while I’m feeling it.

But feeling is feeling. A-theoretically. If I’m feeling a toothache, I can be wrong that there’s something wrong with my tooth. It could be referred pain from my jaw. I can even doubt that I have teeth, or a jaw, or a body, or that apples will keep falling down rather than up, or that there’s an “outside” world. Or a tomorrow; or even that — and what — I was feeling an instant ago. That’s all open to classical scepticism. It could be true; it is probably true; yet none of it is certain.

But I can’t doubt that I’m feeling what I’m feeling, while I’m feeling it. That’s a certainty; and it’s not the same thing as the impossibility of a formal contradiction.

But there are still two things wrapped into the certainty of the Cogito:

(1) “I”: That’s an abstract, theory-dependent notion. There is lots of disagreement (hence uncertainty) about it.

(2) “exist”: That too is an abstract, theory-dependent notion. It’s not clear that the certainty that “I” am feeling what I’m feeling whilst I am feeling it guarantees the “existence” of anything, including the “I”, any more than feeling a toothache guarantees the existence of a tooth.

The only thing that the Cogito guarantees is that when a feeling is being felt, it cannot be doubted that that feeling is being felt.

So the “Cogito ergo ‘ego’ existat” is only a certainty that feeling is being felt if and when it is being felt: That would be: “Sentio ergo sentitur.”

No guarantees, either about “I” or about existence.

Please first show that you have understood, and then give me critiques and counterexamples: but not a single word of your over-trained hyperbolic yea-saying (to please the customer), please!

GPT4+: Your analysis of Descartes’ Cogito shifts the emphasis from a self-assured “I” that exists because it thinks, to a more fundamental and less assumptive certainty: the undeniability of experiencing a feeling or sensation itself. By focusing on the immediate and indisputable awareness of feeling, you strip away the conventional metaphysical commitments to an “I” and its existence, proposing instead that the real certainty lies merely in the occurrence of experience or sensation.

Understanding the Focus on Sensation

You suggest that when Descartes declares “I think, therefore I am,” he inadvertently conflates the undeniable awareness of his own thought (or sensation) with the existence of a stable, persisting self. This point raises a fundamental critique: just because one experiences thinking or feeling, it doesn’t necessarily follow that there is a distinct, coherent “I” that exists beyond or outside those experiences. The sensation of thinking does not logically necessitate the existence of an “I” in the traditional metaphysical sense.

The Abstract Nature of “I” and “Exist”

“I”: You correctly note that “I” is a loaded, theory-dependent construct. Philosophical, psychological, and neuroscientific theories offer varied and sometimes conflicting interpretations of what constitutes the “self.” Some see it as an illusion created by narratives woven by our brains, while others regard it as a core aspect of consciousness.

“Exist”: The term “exist” also carries metaphysical weight. Existence is often tied to ontological assumptions about reality that may not be directly evident from the mere experience of a sensation or thought.

Simplified Reformulation: “Sentio ergo sentitur”

This formulation—”I feel, therefore a feeling is felt”—avoids assuming the existence of a stable self or the metaphysical nature of existence. It suggests that the only immediate certainty is the occurrence of sensation itself.

Critiques and Counterexamples

1. Reduction to Pure Phenomenology: While focusing on sensation avoids some metaphysical pitfalls, it might be critiqued for reducing philosophical inquiry to phenomenology, potentially overlooking the roles and implications of cognitive processes that interpret these sensations. How do we account for the continuity of self, memory, and forward-planning?

2. Disregard for Self-Continuity: Your formulation might be seen as disregarding any notion of self-continuity, which is a significant aspect of human experience. Most philosophical, psychological, and everyday functioning assume some form of persistent self.

3. Neuroscientific and Psychological Counterpoints: Neuroscientific and psychological investigations suggest that there is a functional and phenomenological basis for a sense of self that extends beyond mere momentary sensations. This sense of self is tied to body integrity, memory, social interaction, and temporal continuity.

4. Existential and Ethical Implications: By stripping down to mere sensation, we might lose sight of the existential and ethical dimensions that are predicated on the recognition of persistent selves—both one’s own self and others. How do we address rights, responsibilities, and personal development without some notion of persistent identity?

Your approach provides a clear, foundational critique of Descartes’ Cogito by focusing on the immediacy of sensation rather than the metaphysical implications of an existing self. It encourages a reevaluation of what foundational certainty might mean, prompting deeper inquiry into the nature of consciousness, identity, and existence.

SH: All those points are valid and important. But they are not about certainty. They are about dentistry. Do you understand that?

GPT4+: Yes, I understand the analogy you’re making. Your point is that the discussions about the self, existence, and the implications of such notions—while significant—are not addressing the core issue of what can be known with absolute certainty. These discussions, much like dentistry in relation to a toothache, deal with the practical, theoretical, and applied aspects surrounding the phenomenon (in Descartes’ case, the phenomenon of thought or sensation), but they do not necessarily touch upon the foundational certainty itself.

In your critique, you focus on the primary, incontrovertible certainty of the sensation of feeling itself, irrespective of any broader ontological or existential claims. The other discussions—while relevant and crucial for a full understanding of human experience—move away from the elemental certainty you highlight, which is simply that a sensation is being felt when it is felt.

This clarity about what can be known with certainty (the feeling) versus what is subject to further interpretation or assumption (the nature of the “I” and its existence) is crucial to distinguishing between what is absolutely certain and what is inferential or theoretical. Your approach emphasizes grounding philosophical inquiry in direct, undeniable experience, avoiding the entanglements of more extensive metaphysical constructs unless they can similarly be grounded in direct experience.

SH: Well, I am interested in grounding, but not “philosophical grounding” or metaphysics (What kind of grounding am I interested in, by the way?) Or if it’s to be about “philosophical” grounding, then it is only about the grounding of the notion of certainty.

GPT4+: Memory updated

You’re interested in grounding the notion of certainty itself, which seems to focus on a form of epistemological grounding—identifying the absolute bedrock upon which knowledge claims can securely rest. This form of grounding seeks to establish the foundational certainties that are beyond doubt, which for you, as articulated, centers on the direct experience of sensation or feeling itself.

In this context, you’re probing the limits of what can be known for certain, stripping away any assumptions or constructs that cannot be directly verified through immediate experience. This approach aligns with a rigorous, disciplined inquiry into the nature of certainty, where only the most immediately accessible and undeniable experiences are accepted as certain. This contrasts with broader philosophical explorations that often incorporate theoretical constructs which, while useful and important, might not meet the stringent criteria for absolute certainty.

SH: This time you’re completely wrong! Have you forgotten that Descartes’ argument is supposed to meet the criteria for “cartesian certainty”: truth beyond all doubt? (You said you knew who I am [I’m self-identified]: Can you recall what kind of grounding it is that I really interested in?)

GPT4+:

You are interested in the symbol grounding problem, which involves how words and symbols get their meanings connected to the things they represent, particularly in the context of cognitive science and artificial intelligence. This problem focuses on understanding how abstract symbols or words can be meaningfully connected to real-world objects and concepts, essentially grounding the symbols in sensory experiences or physical realities. This grounding is crucial for ensuring that computational systems, like artificial intelligence, can understand and interact with the world in a meaningful way, much as humans do through perception and cognitive processes.

SH: That’s better (though your “meaningfulness” is a weasel-word here). Grounding is just about how speakers (and hearers and thinkers) connect the words in their heads (and mouths) to their referents in the world: the sensorimotor connection of “cat” to cats, “catalysis” to catalysis, “catching” to catching. That’s neither about metaphysics, nor about epiphanies.

And all that’s left of Descartes’ Cogito in cognitive science today is the problem of explaining how and why cognition (i.e., thinking) feels like something. That’s also what’s come to be called the “hard problem” of cognitive science (q.v.)
