Why Do Human Beings Exist? ー The Limits of Functional Ontology and the Reconstruction of Generative-Resonant Being in the Age of Artificial Intelligence: A Comparative Philosophical Inquiry into Aristotle, Descartes, Locke, Kant, Marx, Arendt, Heideg

1. Short Description This paper argues that artificial intelligence does not make human beings unnecessary by surpassing their functional capabilities; rather, it exposes the limitations of defining human existence through productivity, expertise, and measurable achievements. Drawing on Aristotle, Locke, Kant, Marx, Arendt, Heidegger, Sen, and Nussbaum, it develops Generative Resonance Theory (\(E=\Phi R\)) as a relational and process-oriented alternative. Human existence is reconceptualized through generative possibility, relational participation, crystallized outcomes, and the continuing reopening of future possibilities, while affirming that human dignity remains unconditional. 2. Extended Description The rapid advancement of artificial intelligence has intensified concerns about the future significance of human beings as machines increasingly perform intellectual, professional, and productive functions previously associated with human expertise. Yet the inference from technological substitution to human dispensability rests on an insufficiently examined philosophical assumption: that the value of human existence is determined by the functions individuals perform and the outcomes they produce. This paper investigates that assumption through the concept of functional ontology, understood as the reduction of human existence to identifiable capacities, institutional roles, measurable achievements, and instrumental usefulness. It argues that the contemporary AI crisis reveals not the disappearance of human significance, but the limitations of function-centered interpretations embedded in modern educational, economic, organizational, and technological institutions. Through a comparative philosophical examination of Aristotle's ergon and human flourishing, early modern mechanism, Locke's theory of labor and property, Kant's conception of human dignity, Marx's analysis of alienation, Arendt's account of labor, work, and action, Heidegger's critique of technological enframing, and the capability approaches of Sen and Nussbaum, the paper reconstructs the relationship between function, activity, freedom, dignity, and relational existence. Building on these traditions, the paper introduces Generative Resonance Theory (GRT) as an integrative ontological framework expressed conceptually through \(E=\Phi R\) and the recurrent movement \(\Phi\rightarrow R\rightarrow S\rightarrow\Phi'\). Within this framework, generative possibilities (Φ) develop through relational resonance (R), crystallize into achievements, knowledge, and institutions (S), and may subsequently reopen further possibilities (Φ′). The paper further examines Dynamic Hyper-S, a proposed institutional process through which measurable outcomes become self-reinforcing objectives, potentially weakening the human, social, and ecological conditions that originally generated them. These theoretical distinctions are applied to AI-assisted education, academic research, professional work, economic organization, institutional governance, and technological development. Particular attention is given to the separation between AI-generated outputs and the cultivation of human understanding, as well as the distinction between technological productivity and meaningful social participation. The paper also critically evaluates GRT's limitations, including conceptual ambiguity, insufficient empirical operationalization, the risks of generative meritocracy, potentially oppressive relationships, institutional inequality, and the danger of treating conceptual mathematical expressions as established quantitative laws. Its central conclusion is that human beings need not demonstrate functional superiority over artificial intelligence to possess dignity or participate meaningfully in the world. Human beings do not exist in order to perform functions; rather, functions emerge within the ongoing movement of living. The paper therefore proposes a transition from function-centered institutions toward social arrangements that sustain substantive freedom, human dignity, relational participation, and the continuous regeneration of meaningful possibilities. 3. Research Highlights 1. Challenges functional ontology: Identifies the philosophical error of equating technological replacement of human functions with the disappearance of human significance. 2. Reconstructs a cross-traditional philosophical foundation: Connects Aristotelian activity, Kantian dignity, Marxian alienation, Arendtian natality, Heideggerian being-in-the-world, and contemporary capability theory. 3. Introduces a generative-relational model of existence: Develops \(E=\Phi R\) and \(\Phi\rightarrow R\rightarrow S\rightarrow\Phi'\) as conceptual expressions of relational becoming. 4. Distinguishes performance from understanding: Explains why successful AI-assisted task completion does not necessarily demonstrate the development of independent human capabilities. 5. Identifies Dynamic Hyper-S: Examines how institutional performance indicators can become self-reinforcing objectives detached from the activities they were designed to support. 6. Reinterprets technological substitution: Distinguishes productivity gains from human emancipation, emphasizing the significance of institutional design, ownership, governance, and distribution. 7. Proposes a generative approach to institutional reconstruction: Reconsiders education, universities, labor, economics, and AI governance through participation, autonomy, and institutional openness. 8. Protects unconditional human dignity: Rejects the conversion of creativity, adaptability, or generative capacity into new standards for ranking human worth. 9. Establishes a critical empirical research agenda: Proposes comparative, longitudinal, experimental, and institutional investigations without treating GRT's conceptual equations as validated empirical laws. 10. Reframes the existential question of the AI age: Shifts attention from identifying uniquely human functions toward sustaining the conditions under which human beings can live, relate, participate, withdraw, and begin again. 4. Concise Summaries of All Sections Section 1. Introduction: When Artificial Intelligence Challenges the Meaning of Human Existence Introduces the distinction between functional substitution and existential dispensability through the example of AI-assisted mathematical problem-solving and university assessment. Establishes the central thesis that AI challenges function-centered interpretations of human existence rather than demonstrating human worthlessness. Section 2. Functional Ontology: From Explanatory Method to Institutional Reduction Defines functional ontology as the reduction of existence to identifiable functions, capacities, institutional roles, and measurable outcomes. Explains how legitimate methods of functional description can become problematic when institutional indicators are mistaken for complete accounts of human existence. Section 3. Aristotle: Ergon, Activity, and the Ambiguity of Human Function Reexamines Aristotle's ergon argument and the conception of human flourishing as activity rather than mere achievement. Identifies its relevance to generative existence while questioning whether rational excellence can adequately ground unconditional human dignity. Section 4. Early Modern Mechanism and Locke: From the Explanation of Nature to the Evaluation of Labor Investigates early modern mechanistic explanation and Locke's account of labor and property, distinguishing their original philosophical arguments from later institutional interpretations of productivity. Examines how functional and quantitative reasoning can become associated with the evaluation of human economic contributions. Section 5. Kant: Human Dignity Beyond Instrumental Usefulness Explores Kant's conception of humanity as an end in itself, establishing the distinction between instrumental usefulness and intrinsic moral worth. Demonstrates why technological superiority in functional performance cannot justify treating human beings as replaceable instruments. Section 6. Marx: Alienated Labor and the Separation of Human Activity from Human Life Analyzes Marx's conception of labor as human self-activity and the alienation of workers from their products, activities, social relationships, and species-being. Extends this analysis to AI-mediated production, emphasizing that technological productivity does not automatically generate human emancipation. Section 7. Arendt: Labor, Work, Action, and the Human Capacity to Begin Examines Arendt's distinction among labor, work, and action, highlighting plurality, political freedom, and natality. Connects the capacity to initiate new beginnings with generative possibility while preserving the qualitative differences among human activities. Section 8. Heidegger: Being-in-the-World and the Technological Reduction of Existence Explores Heidegger's account of being-in-the-world and his critique of technological enframing. Interprets the reduction of human beings to measurable and technologically manageable functions as an existential risk of increasingly comprehensive optimization systems. Section 9. Sen and Nussbaum: From Resources and Achievements to Substantive Freedom Compares the capability approach with GRT, emphasizing the distinction among resources, achieved functionings, and substantive opportunities. Proposes that GRT adds a specific focus on how realized achievements and relationships transform the conditions for subsequent possibilities, while acknowledging substantial overlap with established capability theory. Section 10. Generative Resonance Theory: From Functional Identity to Relational Becoming Presents the theoretical architecture of GRT through \(E=\Phi R\) and the recurrent movement \(\Phi\rightarrow R\rightarrow S\rightarrow\Phi'\). Reinterprets human existence through generative possibility and relational participation while distingu
