This paper synthesizes Parts 3 and 4 and extends their implications to epistemology and ethics. We propose a framework termed “materialized idealism”: matter exists eternally as substance, while observers (through measurement basis selection) determine which properties become actualized. We argue that “observer is primary” means: not metaphysically (matter alone is substance), not causally (matter exists independently), but actualizing-wise (measurement basis selection determines which properties become real). This resolves tensions between observer-dependent quantum mechanics and classical physics, and provides rigorous grounding for Nietzsche’s perspectivism without collapsing into relativism. Key contributions: • A coherent interpretation of quantum measurement and classical emergence • Grounding for free will and moral agency within causal structure • Rigorous foundation for perspectivism avoiding both relativism and absolutism • Integration of quantum mechanics, thermodynamics, phenomenology, and ethics • Historical vindication of ancient philosophy and reinterpretation of modern thinkers

Part 3 of this series established that agents (observers) are not epiphenomenal in the determination of their own future states. This paper extends that argument to a fundamental metaphysical principle: observation is not merely epistemic (a way of knowing), but ontological (constitutive of what properties are actually realized). We demonstrate using quantum mechanics, information theory, and the formal structure of measurement that: (1) The universe contains a unique, unchanging material substance M; (2) M possesses a superposition of potential properties; (3) Which properties are actualized depends on the observer’s measurement choice; (4) This is not mysticism; it is the formal structure of quantum mechanics; (5) Classical physics emerges as the special case where measurement choice appears collapsed. Conclusion: Reality is observer-dependent in a rigorous, physically grounded, and non-arbitrary way.
Abstract This paper develops an agent-centric account of measurement that treats the preferred-basis problem as fundamentally perspectival. On this view, the system–apparatus–environment decomposition and the observables that are apt to become classically robust are determined by the physical constitution and epistemic constraints of an embodied class of agents. Decoherence then stabilises those agent-specified observables, yielding facts that are stable for us without positing an absolute, observer-independent basis. On this picture, ‘measurements’ are public not because they are metaphysically privileged, but because agents like us share the relevant sensorimotor and operational structure. I motivate this account through a discussion of two recent no-go results for relational quantum mechanics (RQM) [1, 2], and a subsequent response [3]: my aim is not to defend RQM per se, but to refine the relational insight with a principled account of basis selection rooted in embodiment. I provide a phenomenological gloss, drawing on body-schema considerations, to argue that quantum mechanics is best understood as an idiosyncratically human description of interactions with the physical world—a structurally constrained, agent-indexed framework within which classicality emerges.
This thesis investigates the structural analogy between Nietzsche's perspectivism and Carlo Rovelli's Relational Quantum Mechanics (RQM) with the aim of proposing an epistemic- ontological model of the observer. It proceeds from the premise that both frameworks share a central idea: knowledge and physical properties do not exist in absolute terms, but always only relative to the perspective or system from which they are constituted. The thesis first traces the development of Nietzsche's perspectivism across three phases of his work and analyses his concepts of the will to power, the deconstruction of the subject, and the three metamorphoses of the spirit. It then surveys the main interpretations of quantum mechanics before offering a detailed analysis of RQM, including its postulates, the concept of stable facts, and the problem of intersubjectivity. On the basis of a comparative analysis of both frameworks, the thesis identifies their shared structural features while also delineating the methodological limits of the analogy. In the concluding part, the thesis proposes an original epistemic- ontological model of the observer that integrates insights from both traditions as well as from Luhmann's theory of observation. In this model, the observer is understood as a process constituted by relations,...
This paper offers a conceptual and formal analysis of non-absoluteness in perspectival interpretations of quantum mechanics. Extended Wigner-type experiments reveal a fundamental tension between the universality of quantum mechanics, the absoluteness of observed events, and the possibility of intersubjective agreement. I argue that denying observer-independent events cannot remain a mere interpretive slogan: it requires a precise account of how perspectival statements, tracking assumptions, meta-level descriptions, and intersubjective communication are to be formulated. Many existing approaches either implicitly reintroduce observer-independent structure or leave key notions underdetermined. Within this framework, Convivial Solipsism provides a coherent account of non-absolute events, preserving the universality of quantum mechanics while rejecting the need for a global viewpoint. To make this claim precise, the paper introduces the basic elements of a formal perspectival logic designed to distinguish well-formed perspectival statements from illegitimate unindexed or absolutizing statements. The paper concludes that scientific objectivity need not rest on observer-independent facts, but can instead be grounded in the internal coherence of perspectival structures.
This paper presents a conceptual and philosophical interpretation of quantum measurement, focusing on the role of human intention as a metaphysical variable in the process commonly described as wave-function collapse. Rather than proposing a physical mechanism or experimentally testable claim, the work examines how intention, observation, and meaning-making may be understood within the broader limits of scientific epistemology. The paper argues that science functions as a powerful methodological tool for modeling observable phenomena, but that its scope is necessarily bounded by empirical measurement and repeatability. Within this framework, the study explores how trans-empirical aspects of experience—such as intention, consciousness, and belief—can be discussed without being reduced to physical causation. The emphasis is not on rejecting scientific inquiry, but on clarifying its domain of applicability. Using concepts from quantum mechanics (superposition, collapse, observer-dependence) as interpretive structures, the paper develops a metaphysical model in which collapse is understood as a process of selection aligned with intention, rather than as a solely mechanical outcome of measurement. Behavioral and cognitive examples are presented as illustrative analogies, not as quantum experiments. This work is situated at the intersection of philosophy of science, consciousness studies, and conceptual interpretations of quantum mechanics. It contributes to the ongoing development of Javed’s Quantum Thought, a framework that seeks to integrate scientific reasoning with broader ontological reflection while maintaining clear distinctions between empirical science and metaphysical interpretation.
