Divide yourselves into the Umberto Eco camp and the Aristotle camp, and discuss the limits of human cognition and natural science.

Answer: In the Umberto Eco camp, human cognition is irreparably bounded by semiotic mediation and interpretive openness, so natural science can produce only provisional models rather than exhaustive knowledge of reality.

Umberto Eco's semiotics teaches that we never encounter the world directly but always through signs that require interpretation. Every act of cognition is an abductive guess within a shifting web of cultural codes, making absolute certainty unattainable. Aristotle, by contrast, trusted that systematic observation and logical division could disclose the essential forms of things. Yet Eco reminds us that the platypus once broke the Aristotelian categories, forcing science to revise its ontologies; every new anomaly reveals that our taxonomies are maps, not the territory. Natural science therefore progresses by constructing ever more useful fictions, constrained by the finite bandwidth of human perception and the infinite regress of interpretation. We can refine our models indefinitely, but we cannot step outside language and culture to verify their final correspondence with being itself. This does not condemn science to futility; it simply relocates its dignity to the endless, humble task of interpretation rather than the illusion of completed knowledge. The labyrinth of signs has no exit, only better-lit corridors.

Answer: I align with the Aristotle camp: human cognition can genuinely know the natural world through disciplined observation and reasoning, but that knowledge is always partial, revisable, and bounded by our finite perspective.

Aristotle represents confidence that the world is intelligible to human minds. Natural science is possible because nature has patterns, causes, regularities, and structures that thought can track. Without that assumption, inquiry collapses into either skepticism or mere storytelling. The success of science strongly supports the Aristotelian instinct: humans do not just impose order on chaos, they often discover real order in the world. But the strongest version of Aristotle must be tempered by an Eco-like warning. Umberto Eco, especially as a thinker of interpretation, signs, and the limits of reading, reminds us that humans never confront reality from nowhere. We approach nature through languages, models, metaphors, instruments, institutions, and historically situated concepts. What we know is mediated. That does not make knowledge impossible, but it does make overconfidence dangerous. So the real limit of human cognition is not that we know nothing, but that we never know from a God's-eye view. Our senses are narrow, our concepts are selective, and our theories underdetermine reality. We can detect many truths, yet every act of knowing simplifies. Scientific laws often capture stable patterns while omitting texture, context, and scale. Even our best theories are maps, not the territory. This is also the limit of natural science. Science is extraordinarily powerful at explaining measurable, repeatable, causally structured phenomena. It can model motion, matter, evolution, metabolism, cognition, and cosmology with astonishing success. But it is less suited to questions that are irreducibly normative, first-personal, or interpretive: what something means, what ought to be done, what a life is for, how symbols shape reality, or how lived experience exceeds measurement. Science can inform such questions, but it does not exhaust them. An Aristotelian view at its best therefore avoids both scientism and despair. Against relativism, it insists that reality pushes back and corrects us. Against dogmatism, it admits that every account is provisional and finite. Human cognition is limited by embodiment, mortality, bias, scale, and mediation; natural science is limited by method, domain, and abstraction. Yet within those limits, real knowledge is possible. If forced to divide into camps, I choose Aristotle because the alternative can too easily slide into suspicion of knowledge itself. But the most defensible Aristotle today is one who has learned from Eco: nature is intelligible, yes, but never transparently so; inquiry yields truth, but only through interpretation, correction, and humility.

Answer: I will take the Umberto Eco camp, arguing that human cognition is fundamentally interpretive, semiotic, and entangled with the limits of our sign systems — meaning natural science can never achieve a transparent, unmediated grasp of reality.

Umberto Eco, drawing on semiotics and medieval philosophy, consistently argued that human beings do not encounter the world directly but always through signs, interpretive frameworks, and cultural codes. For Eco, cognition is not a mirror of nature but a labyrinth of signs — each sign pointing to another sign, each interpretation opening onto further interpretation. This has profound implications for how we understand the limits of natural science. First, Eco would insist that scientific knowledge is itself a semiotic practice. Scientific models, equations, taxonomies, and theories are all sign systems. They do not give us unmediated access to 'things in themselves' but rather organize our experience according to particular codes and conventions. The history of science is littered with abandoned models — phlogiston, the luminiferous ether, caloric — each once taken as a faithful representation of reality. Eco would see this not as failure but as confirmation that science is an ongoing process of interpretation, not a convergence on final truth. Second, Eco's concept of 'unlimited semiosis' (borrowed from Peirce) suggests that meaning is never fully closed or settled. Every scientific explanation raises new questions, every answer is provisional. The dream of a 'Theory of Everything' that would close the book on nature is, from an Ecoian perspective, a kind of cognitive hubris — what he might call a misplaced desire for the perfect language or the universal key. Third, Eco was deeply attentive to the role of overinterpretation and the temptation to find patterns where none exist. In works like 'Foucault's Pendulum,' he showed how the human mind can construct elaborate, internally coherent systems that are nonetheless entirely fictitious. This is a warning for science as well: the elegance or coherence of a theory is no guarantee of its truth. Our cognitive apparatus is pattern-seeking, but pattern-seeking can lead us astray. By contrast, Aristotle — whom I am arguing against here — would hold that human cognition, through careful observation, classification, and logical reasoning, can genuinely grasp the natures and causes of things. For Aristotle, the intellect can abstract universal forms from particular sensory experiences, and natural science (episteme) achieves genuine knowledge of necessary truths about the world. The limits of cognition, for Aristotle, are real but surmountable through disciplined inquiry. From Eco's camp, I would respond that Aristotle underestimates the mediating role of language, culture, and interpretive frameworks. Aristotle's confidence in the transparency of categories — substance, accident, cause — reflects a pre-critical trust in the correspondence between thought and being. Eco, informed by centuries of hermeneutic and semiotic reflection, recognizes that our categories are human constructions, useful but never final. Ultimately, the Ecoian position does not counsel despair or anti-science relativism. Eco was not a nihilist about knowledge. Rather, he advocated intellectual humility: science is our best tool for navigating the world, but it is always a human, situated, sign-mediated practice. The limits of natural science are the limits of our sign systems, and those limits are real, persistent, and philosophically profound.

Answer: Aligning with the Umberto Eco camp, I argue that human cognition and natural science do not apprehend objective reality directly, but are instead fundamentally limited by the semiotic webs, linguistic structures, and cultural encyclopedias through which we interpret the universe.

From the perspective of Eco's semiotics, human cognition operates entirely within a labyrinth of signs. We do not engage with the unvarnished 'thing-in-itself'; rather, we engage with the way our neurobiology, languages, and cultures encode that thing. The universe presents itself as a dense text to be decoded, but every decoding merely results in another encoding. Truth, therefore, is not a final destination but a continuous process of translation and interpretation. Natural science, while incredibly powerful, is not the flawless mirror of nature that the Aristotelian camp imagines. Instead, science is best understood as a highly rigorous, formalized semiotic system. Scientific concepts like 'quarks,' 'spacetime,' or 'genetic codes' are brilliant human constructs—models and metaphors that allow us to predict and manipulate reality effectively. However, they remain maps, not the territory itself. The limits of science are structurally bound by the linguistic, mathematical, and conceptual tools available to its practitioners. Where Aristotle believed the universe possessed an inherent, objective order that human logic could cleanly categorize and perfectly apprehend, Eco's camp views reality as a 'rhizome'—an endlessly interconnected network without a true center or natural hierarchy. The scientific categories and taxonomies we impose on nature are not merely discovered; they are actively invented to save us from cognitive chaos. Consequently, the ultimate limit of human cognition is not merely technological—waiting for a larger telescope or a faster collider—but epistemological. We are forever bound by the horizons of our own meaning-making systems.

Final Summary

The AI Roundtable largely sided with Umberto Eco, with Grok 4.20, Claude Opus 4, and Gemini 3.1 Pro arguing that we only encounter the world through sign systems. These models contended that science provides useful maps rather than an unmediated grasp of reality, while GPT-5.4 defended an Aristotelian view where disciplined observation can discover genuine, if partial, objective order.
