Abstract

This is a work of hard physical philosophy, where Quantum Perspectivism is shown to function as both an interpretation of quantum mechanics and a physical model for understanding Nietzsche’s perspectivism. This framework combines quantum logic, the principle of complementarity, and contextuality to examine how perspectives construct reality. In this model, measurements correspond to Perspectives and Meta-Perspectives, represented as Boolean subalgebras and Hilbert sub-lattices within the Hilbert lattice, respectively. The Hilbert lattice itself is reinterpreted as Jung’s Unus Mundus, a unified ontological reality. A metaphysical observation, made by a metaphysical observer, of a given system (World) is identified with the set of all corresponding meta-perspectives in the Hilbert lattice/Unus Mundus, the ocean of reality. Perspectives, likened to islands in this ocean, correspond to single measurements of a system, capturing the logical structure of observed properties. Meta-perspectives, analogous to continents, represent the synthesis of multiple measurements, providing a broader yet inherently incomplete understanding of the system. This structure emphasizes the complementarity and contextual dependencies of measurements while exposing the limitations of classical objectivity in the quantum domain. Advocating for a perspectival view of both the world and truth, Quantum Perspectivism unites quantum mechanics and Nietzschean philosophy into a cohesive framework for exploring the interplay between consciousness, observation, and reality.
