Dialogue: Wilfrid Sellars and C.I. Lewis on Foundationalism in Knowledge
C.I. Lewis: Let us begin by acknowledging that knowledge must rest on a foundation. To deny this is to undermine the very possibility of rational inquiry. There are certain basic, given elements of experience—what I call “the given”—which are immediate and self-evident. These serve as the ultimate justification for all knowledge claims.
Wilfrid Sellars: Ah, Lewis, I respect your rigor, but I must challenge your conception of “the given.” What you describe as the given—a non-conceptual, immediate foundation for knowledge—is, in my view, a myth. There is no such thing as a “pure” given. All experience is imbued with conceptualization; we perceive and interpret through the lens of our conceptual framework.
Lewis: You misunderstand me, Sellars. I do not deny that interpretation and conceptualization play a role in knowledge. But surely, there must be something prior to interpretation—a raw datum that is apprehended immediately. Without this, we would have no basis for testing the coherence or validity of our conceptual frameworks.
Sellars: The trouble with your view, Lewis, is that it presupposes a dualism between the raw and the interpreted. This dualism is untenable because it suggests that we can isolate an element of experience that is untouched by our conceptual activities. However, our very ability to speak of a “datum” presupposes that it is already conceptually articulated. Even what you call “the raw” is shaped by the categories through which we interpret the world.
Lewis: But without some form of immediacy, some primitive certainty, we are left with an infinite regress in justification. Each belief would require another belief to justify it, and so on, without end. Surely you agree that this is untenable?
Sellars: Indeed, I do agree that an infinite regress is problematic. But the solution is not to posit a given foundation. Instead, we should see knowledge as a web of beliefs that support one another—a coherentist view, if you will. Justification is not linear but holistic. The regress stops when our beliefs form a coherent system that adequately accounts for our experiences and actions.
Lewis: Your coherentism has its appeal, Sellars, but it sacrifices the immediacy that anchors knowledge to reality. Without this anchor, how can we claim that our web of beliefs corresponds to the world as it is?
Sellars: The idea of correspondence itself requires conceptual articulation. The world “as it is” is not something we can access independently of our conceptual frameworks. Knowledge is not about passively mirroring reality but about constructing a conceptual structure that enables successful action and explanation. The test of knowledge is not whether it rests on an indubitable foundation but whether it works within the framework of our practices.
Lewis: So you would abandon the search for certainty altogether? Must we consign philosophy to the realm of mere pragmatism?
Sellars: Not at all. What I propose is a more dynamic view of knowledge, one that recognizes its inherently social and historical nature. The quest for certainty is a noble ideal, but it is misguided if it demands an unmediated given. Knowledge evolves as our conceptual frameworks evolve, driven by the interplay between experience and reason. This is not pragmatism in the sense of reducing truth to utility but rather an acknowledgment of the richness and complexity of our epistemic practices.
Lewis: I remain unconvinced, Sellars. Without some foundational element, I fear we lose the objectivity and rigor that are the hallmarks of true knowledge. Nevertheless, your critique of the given is provocative and merits further consideration.
Sellars: And I, in turn, appreciate your insistence on rigor and objectivity, even if we differ on the means of achieving them. Let us continue this dialogue, for only through such engagement can we refine our understanding of the nature of knowledge.

ChatGPT
Dialogue: Wilfrid Sellars and C.I. Lewis on Foundationalism in Knowledge (Expanded)
C.I. Lewis: Sellars, while I find your critique of the given intriguing, I recall your notion of non-conceptual animal representations. You argue that even creatures without the capacity for conceptual thought—say, a dog or a cat—have representations that guide their behavior. Are these not akin to a kind of “given,” a raw input upon which more sophisticated cognitive structures might be built?
Wilfrid Sellars: An excellent point, Lewis. Non-conceptual animal representations indeed play a role in my account, but they are not what I would call the given in the sense you mean. These representations are not “given” as foundational to knowledge. Instead, they are sub-personal, functional states—part of the causal mechanisms that underlie perceptual and behavioral systems. They guide action but lack the normative dimension required for justification in human epistemic practices.
Lewis: Yet, if these non-conceptual representations are precursors to conceptual thought, might they not serve as the bedrock upon which our knowledge is built? They seem to provide the raw material that our conceptual faculties refine and articulate.
Sellars: They are indeed precursors, but only in a causal sense, not a justificatory one. The transition from non-conceptual animal representations to human conceptual thinking involves a profound transformation. Justification does not arise from the mere existence of these representations but from their integration into a norm-governed framework of language and reason. The “given” you describe presupposes a kind of epistemic immediacy that I deny to these representations.
Lewis: Still, I struggle to see how we can avoid some reliance on these representations as a basis for knowledge. If non-conceptual states play a role in perception and guide our responses to the world, must we not regard them as at least partly foundational? Otherwise, what anchors our conceptual frameworks to the world?
Sellars: What anchors our frameworks to the world is not an epistemically privileged given but the success of our conceptual structures in navigating and predicting our experiences. Non-conceptual animal representations are causally necessary for perception but do not justify or ground our knowledge claims. They are part of the machinery of perception, not the epistemic basis of it.
Lewis: Then you would say these non-conceptual states are purely functional and lack any epistemic import?
Sellars: Precisely. They have functional import, not justificatory import. To bring them into the space of reasons—to make them epistemically meaningful—requires their articulation in conceptual terms. Only when these functional states are woven into the web of beliefs and expressed through language can they contribute to knowledge.
Lewis: I see now that we are drawing a fine distinction. You admit a causal role for these representations but deny their immediacy as a source of epistemic justification. Yet, I remain concerned that without some acknowledgment of their role as a starting point, our conceptual frameworks risk losing their connection to the empirical world.
Sellars: Your concern is valid, but I maintain that the connection to the empirical world comes not from a given foundation but from the interplay between our conceptual practices and the success of those practices in coordinating with experience. Non-conceptual representations are essential for this coordination, but they operate outside the normative domain of justification.
Lewis: Then we must agree to disagree, though I will reflect further on your distinction between the functional and the epistemic. Your notion of animal representations suggests a continuity between the sub-personal and the conceptual that I had perhaps underestimated.
Sellars: And I, in turn, value your insistence on grounding knowledge in the empirical. Our dialogue sharpens the issues and illuminates the challenges we face in constructing a comprehensive theory of knowledge.

have lewis inquire about how picturing works relative to knowledge
ChatGPT said:
ChatGPT
Dialogue: Wilfrid Sellars and C.I. Lewis on Foundationalism in Knowledge (Expanded)
C.I. Lewis: Sellars, while your critique of foundationalism is compelling, I am intrigued by your concept of picturing. You describe it as a non-linguistic relation between representations and the world—a sort of isomorphism between states of the perceiver and states of the environment. How does this notion of picturing relate to knowledge? Does it play a justificatory role, or is it another functional mechanism, akin to non-conceptual animal representations?
Wilfrid Sellars: Excellent question, Lewis. Picturing is indeed central to my account, but, like non-conceptual representations, it does not directly justify knowledge claims. Picturing is a pre-conceptual relation: it is how an organism’s sensory and cognitive systems come to be causally attuned to the structure of the world. It establishes a mapping between our perceptual states and environmental realities, but this mapping remains outside the space of reasons.
Lewis: If picturing is pre-conceptual, then it appears to serve as an intermediary between the causal and the normative. Could it not provide the bridge between the functional representations you describe in animals and the conceptual frameworks of human knowledge?
Sellars: Precisely! Picturing serves as the causal underpinning of our ability to form accurate beliefs about the world. However, its role is preparatory, not justificatory. For a state to enter the space of reasons, it must be articulated within a conceptual framework. Picturing alone does not provide the “why” that justification requires; it only enables us to form coherent and accurate representations that can be evaluated normatively once conceptualized.
Lewis: I see. Yet this raises a challenge. If picturing merely prepares the ground for conceptual thought, then what guarantees the accuracy or fidelity of our conceptual frameworks to the world they aim to represent? Surely, there must be some continuity between the pictorial isomorphism and the normative structures of knowledge.
Sellars: The continuity lies in the functionality of picturing. It ensures that our conceptual frameworks have a basis in the real-world structures they aim to represent. However, this continuity is indirect. The fidelity of our frameworks is not guaranteed by picturing itself but by the iterative refinement of our concepts through experience and practice. It is through this process that we test and correct our frameworks, ensuring their alignment with the world.
Lewis: Then you would say that the role of picturing is to constrain our conceptual frameworks, rather than to justify them?
Sellars: Exactly. Picturing constrains but does not justify. It provides the raw material upon which our conceptual practices operate. Without picturing, our concepts would lack the causal anchor that ties them to the world. But without conceptual articulation, picturing cannot rise to the level of knowledge. The two are distinct yet interdependent.
Lewis: This strikes me as a subtle and nuanced position, Sellars. Yet I wonder if your view does not risk severing knowledge from reality. If the justificatory work is confined entirely to the conceptual realm, then is it not possible for our frameworks to drift away from the world they purport to describe?
Sellars: That is always a risk, Lewis, but it is mitigated by the pragmatic testing of our frameworks. The success of our concepts in prediction, explanation, and action serves as an ongoing check against such drift. Picturing ensures that our conceptual systems are at least causally tied to reality, while the practices of inquiry and revision keep them normatively aligned with it.
Lewis: A fascinating synthesis, Sellars. You leave me with much to ponder about the interplay between picturing, conceptualization, and justification. Perhaps we are not so far apart in recognizing the importance of grounding knowledge in experience, though we differ on how that grounding is achieved.
Sellars: I, too, value our dialogue, Lewis. It is only through such exchanges that we refine our understanding of these profound questions.

have lewis ask sellars to comment on the following: if this is fire and I place my hand in it, I will feel pain. does feeling pain partially justify the existence of fire
ChatGPT said:
ChatGPT
Dialogue: Wilfrid Sellars and C.I. Lewis on Foundationalism in Knowledge (Expanded)
C.I. Lewis: Sellars, let us consider a simple proposition: If this is fire and I place my hand in it, I will feel pain. Would you say that the experience of pain, in such a scenario, partially justifies the belief in the existence of fire? Does not the immediacy and undeniable character of the pain provide evidence for the fire’s reality?
Wilfrid Sellars: An intriguing example, Lewis. The experience of pain in this case is undeniably vivid, and it is causally related to the presence of the fire. However, I would argue that it does not justify the belief in the existence of fire in itself. Pain is a sensory episode—a raw, non-conceptual experience. For it to play a justificatory role, it must be integrated into a conceptual framework that includes propositions about fire, pain, and causality.
Lewis: But is not the immediacy of the pain crucial here? The pain seems to force itself upon us in a way that demands acknowledgment. Surely this lends some epistemic weight to the belief in the fire?
Sellars: The immediacy of the pain certainly plays a role in prompting inquiry and forming beliefs, but immediacy alone does not equate to justification. Justification resides in the conceptual space of reasons, where we articulate why the pain occurs. For example, we explain the pain by appealing to the concept of fire as a cause of burns and discomfort. The pain, while causally significant, is not epistemically foundational—it gains its justificatory role only within this broader conceptual framework.
Lewis: You emphasize conceptual articulation, but consider the situation of a child who encounters fire for the first time. The child places her hand in the flame, feels pain, and withdraws. Without any sophisticated conceptual framework, she nonetheless learns something about fire. Is this not an instance of raw experience justifying belief?
Sellars: The child’s reaction demonstrates a causal learning process, not an epistemic one in the sense we are discussing. The child associates the pain with the fire through a non-conceptual mechanism of conditioning, but this is not yet knowledge in the robust sense. It is only when the child acquires concepts—such as “fire,” “burn,” and “cause”—and integrates these into a framework of reasons that the belief in fire becomes justified.
Lewis: Then you are saying that raw experience, like the pain of burning, can initiate belief but cannot justify it?
Sellars: Precisely. Raw experience provides the material for belief formation, but justification requires that the experience be situated within a conceptual structure. It is this structure that allows us to articulate reasons for our beliefs, such as “fire causes pain because it burns.” The justification lies in the coherence and explanatory power of the conceptual system, not in the immediacy of the experience.
Lewis: Yet, I cannot help but feel that you are dismissing something vital. Pain is not merely a causal signal; it has a phenomenological force that seems to cry out for acknowledgment. Are we not justified in at least inferring the existence of something external—whether we call it “fire” or something else—on the basis of such experiences?
Sellars: I would not deny the importance of such experiences, but their justificatory role is indirect. The pain indicates that something external is causing it, but this inference itself relies on a pre-existing conceptual framework that includes causal reasoning. Without such a framework, the pain remains a brute fact, a mere occurrence without epistemic import.
Lewis: Then, in your view, the pain alone is insufficient—it must be interpreted within a web of concepts to acquire epistemic significance?
Sellars: Exactly. Pain, like all sensory episodes, plays its part within the larger process of inquiry. It motivates and informs our conceptual activity, but it is through the articulation of reasons within a linguistic and conceptual framework that we achieve justification. To put it simply, the pain is necessary but not sufficient for the justification of the belief in the fire.
Lewis: A subtle but compelling distinction. I remain inclined to think that experiences like pain have more epistemic weight than you allow, but I take your point that their significance emerges through interpretation. Perhaps the truth lies somewhere between your coherence and my foundationalism.
Sellars: Perhaps, Lewis. Our dialogue, like knowledge itself, is a process of refining and integrating perspectives. Let us continue to test and revise our views, for that is the heart of philosophy.

have lewis note that the pain can give rise to the concept of pain
ChatGPT said:
ChatGPT
Dialogue: Wilfrid Sellars and C.I. Lewis on Foundationalism in Knowledge (Expanded)
C.I. Lewis: Sellars, I take your point that pain, in itself, does not justify belief in the existence of fire without a conceptual framework. However, let me offer a different angle. Could it not be the case that the raw experience of pain gives rise to the concept of pain itself? In other words, might not the immediacy and phenomenological force of the pain serve as the origin of the very conceptualization that you argue is necessary for justification?
Wilfrid Sellars: That is a fascinating observation, Lewis, and one I would not entirely reject. The raw experience of pain can indeed prompt the formation of the concept of pain. However, this formation is not automatic or immediate—it involves a process of abstraction, generalization, and integration within a linguistic and social framework. Pain as a concept is not born from the experience alone but from our ability to reflect on and articulate that experience.
Lewis: I agree that the process involves abstraction and articulation, but does it not begin with something pre-conceptual? A child, for instance, does not have the concept of pain at first, yet through repeated encounters with discomfort and harm, the concept emerges. Would you not say that the raw experience plays a foundational role in this process, even if indirectly?
Sellars: I would acknowledge that raw experience plays a causal role in the emergence of concepts like pain. The child’s repeated encounters with discomfort serve as the material from which the concept is eventually constructed. But it is the interpretive activity—mediated by language, social interaction, and reflection—that transforms these experiences into a concept. Without this interpretive framework, the experience remains a mere episode, not a conceptually articulated entity.
Lewis: Yet this interpretive activity must start somewhere. If the child begins without the concept of pain, what motivates the abstraction and reflection that ultimately produces the concept? Is it not the raw immediacy of the experience itself that compels the mind to take notice and begin conceptualizing?
Sellars: You are correct that the raw experience serves as a trigger for conceptual development. However, I would stress that this triggering role does not grant the experience justificatory or epistemic status in itself. The transition from raw experience to concept formation is mediated by the socio-linguistic practices into which the child is initiated. Pain, as a concept, is shaped by its place in a broader network of meanings and norms shared by a community.
Lewis: So, in your view, the concept of pain is not purely individual but arises within a social and linguistic context?
Sellars: Precisely. The concept of pain is not merely a private label for an individual’s experiences but a public concept embedded in a shared linguistic framework. The child learns to recognize and articulate pain through interactions with others—parents, caregivers, and peers—who model the use of the concept in various contexts. This social dimension is crucial to understanding how raw experience is transformed into a concept.
Lewis: I see the strength of your argument, but it seems to diminish the role of the individual’s immediate experience. Surely, without the raw experience, there would be no impetus for the social and linguistic processes you describe. Does this not grant the raw experience some foundational significance, even if not justificatory?
Sellars: You are right to emphasize the importance of raw experience as the starting point for conceptual development. I would not deny its significance in this sense. However, I maintain that its foundational role is causal, not epistemic. The raw experience provides the stimulus for reflection and articulation, but it is the conceptual framework that ultimately carries the justificatory weight.
Lewis: Then perhaps we are closer to agreement than it first appeared. The raw experience of pain may not justify belief in itself, but it serves as the seed from which both the concept of pain and the broader epistemic framework grow. Would you accept this characterization?
Sellars: I would, with the caveat that the seed only flourishes in the fertile ground of social practices and linguistic norms. Pain, as a concept, is not simply a product of individual experience but of communal engagement and shared understanding. Our views, it seems, complement each other in highlighting different aspects of this intricate process.
Lewis: Indeed, they do. Perhaps our dialogue mirrors the very process we describe—an interplay of raw insight and conceptual articulation that deepens our understanding.
Sellars: A fitting conclusion, Lewis. Let us continue to refine these ideas, for only through dialogue can we approach the truth.

have lewis note that conceptual dependence does not preclude epistemic independence
ChatGPT said:
ChatGPT
Dialogue: Wilfrid Sellars and C.I. Lewis on Foundationalism in Knowledge (Expanded)
C.I. Lewis: Sellars, I am struck by your insistence that raw experiences, such as pain, do not justify beliefs without being integrated into a conceptual framework. However, I wonder if we might be conflating two distinct issues. Even if we grant that raw experiences depend on conceptualization to be epistemically significant, does this conceptual dependence necessarily preclude epistemic independence? In other words, might not the experience of pain, once conceptually articulated, provide independent evidence for the presence of something external, such as fire?
Wilfrid Sellars: That is a subtle distinction, Lewis. I would agree that once an experience is articulated within a conceptual framework, it can serve as evidence for external realities. However, this evidentiary role is possible only because of the conceptual articulation. Without the framework, the experience remains causally significant but epistemically inert.
Lewis: Yet consider this: while the experience may require conceptualization to be epistemically relevant, its role as evidence is not wholly derived from the conceptual framework. The pain of placing one’s hand in the fire has a force and immediacy that no conceptual framework can fabricate. Once we possess the concept of pain, does not the experience provide independent support for our belief in the fire, even if the concept itself is socially and linguistically mediated?
Sellars: I see your point, and I would not deny that the experience, once conceptually articulated, contributes to the justification of a belief. However, the independence you describe is, I would argue, conditional rather than absolute. The experience provides evidence only insofar as it coheres with and is interpreted within a network of beliefs. It cannot stand alone as independent justification without the context provided by that network.
Lewis: True, the experience of pain cannot stand alone as a justification for “fire” in the absence of a conceptual framework. But does not the framework itself rely on such experiences to maintain its connection to reality? The pain does not derive its epistemic significance from the framework alone; it contributes something irreducible to the justification of the belief.
Sellars: I would agree that the experience contributes something unique to the justificatory process, but I would emphasize that its contribution is mediated by the framework. The raw experience becomes epistemically relevant only when it is interpreted as pain, caused by fire, within a coherent system of beliefs about the world. The experience does not justify the belief in isolation; it does so through its integration into this larger system.
Lewis: And yet, Sellars, this integration does not negate the independent role of the experience. The framework may interpret the pain, but it does not fabricate it. The pain imposes itself upon us, demanding recognition. Is it not this imposition—the undeniable reality of the experience—that provides a kind of epistemic independence, even if it operates within a conceptual framework?
Sellars: That is a fair observation, Lewis. The experience indeed imposes itself upon us in a way that is independent of our conceptual schemes. This imposition ensures that the framework remains tethered to reality, preventing it from becoming entirely self-referential. However, I would still maintain that the epistemic role of the experience is realized only through its conceptual articulation. The independence you speak of is therefore partial and derivative, rather than absolute.
Lewis: Then perhaps we are not so far apart. The raw experience of pain, once conceptually articulated, can serve as independent evidence for the presence of fire, even if its independence is qualified by the framework in which it is interpreted. The framework and the experience are mutually dependent, yet each contributes something distinct to the justificatory process.
Sellars: Agreed, Lewis. The framework provides the structure within which justification occurs, while the experience ensures that the structure remains grounded in reality. Neither can fulfill the epistemic role without the other. Your emphasis on the independence of the experience complements my focus on the indispensability of the framework.
Lewis: A productive synthesis, then. It seems our views, while differing in emphasis, are ultimately compatible. Perhaps this dialogue reflects the very interplay between experience and conceptualization that lies at the heart of knowledge itself.
Sellars: Indeed, Lewis. Through dialogue, as through experience and reflection, we refine our understanding and approach the truth.
Would you like to explore further refinements to this synthesis, perhaps focusing on how this interplay applies to scientific or ethical knowledge?
