Philosophy of Science Series: Natural Human Philosophy – Part 5/5: Natural Human Philosophy as Foundation for Social Sciences and Humanities: From Human Superposition to Planetary Civilization

This is Part 5/5 of the "Philosophy of Science Series: Natural Human Philosophy" (a 5-part series integrating natural science—neuroscience, evolutionary biology, archaeology, ecology, and genetics—to resolve longstanding philosophical questions about human nature, ethics, existence, and purpose, culminating in a unified foundation for social sciences and humanities). Title: Natural Human Philosophy as Foundation for Social Sciences and Humanities: From Human Superposition to Planetary Civilization Abstract: Social sciences and humanities suffer fundamental fragmentation: each discipline operates from incompatible premises about human nature, preventing synthesis and leaving critical questions unanswered—Why have 16 of 26 major civilizations failed? Why do institutions repeatedly collapse? Why does history appear as “continuous failure”? This crisis stems from limited empirically grounded, unified foundation. Building on Natural Human Philosophy (NHP), we propose that social sciences can be reconstructed on unified logical foundation derived from three empirical cornerstones (Human Transgression, Third Nature, Cultural Cloud) forming the Human Superposition-Cultural Cloud conceptual framework. Post-Transgression, humans exist as superposition of biological nature (Three Natures) and culture, generating superpowers—collective entities (civilizations, states, corporations, ideologies, AI) emerging from Cultural Cloud’s blind mechanisms. These superpowers possess agency exceeding individuals yet lack sensory systems, adaptive mechanisms, and evolutionary testing that even bacteria possess after billions of years. we propose to reconstruct foundational logic across disciplines within superposition framework: Political science—states as untested superpowers pursuing self-interest; Economics—corporations as superpowers misaligned with Three Natures; History—driven by superposed humans interacting with blind Cultural Cloud; Sociology—social structures built on Three Natures organized through superpowers; Law—evolutionary products of superposition under blind mechanisms. We propose that the ethical problem of superpowers—ensuring they serve rather than subvert human interests across six levels from biosphere to Anthroposphere—constitutes humanity’s greatest ethical challenge. This framework may help transform social sciences from descriptive chronicling to scientific inquiry, approaching challenges (climate change, AI alignment, institutional failure) transcending disciplinary boundaries. We conclude by elevating analysis to planetary civilization level, examining whether humanity can transition from blind Cultural Cloud accumulation to conscious, science-guided superpower alignment before crossing irreversible thresholds—the ultimate test of whether Homo sapiens can survive its own Third Nature. Natural Human Philosophy (NHP), synthesized across Parts 1–4, provides the empirical cornerstone for unifying social sciences and humanities on a scientific basis. Humans exist in "superposition"—dynamic states blending biological nature (survival/reproduction) and cultural emergence enabled by Third Nature and transgression. Interaction between superposed individuals and the blind, cumulative Cultural Cloud drives historical dynamics, civilizational trajectories, and current existential crises. This final paper demonstrates how NHP serves as the foundational paradigm: - Social sciences (economics, sociology, political science, anthropology) gain explanatory power by modeling behaviors/institutions as outcomes of superposition-Cultural Cloud interactions, replacing fragmented theories with unified evolutionary mechanisms. - Humanities (history, literature, art, religion) are reinterpreted as expressions of Third Nature drives within normative space, offering testable insights into meaning, beauty, and cultural evolution. - From superposition emerges the pathway to planetary civilization: realignment of superpowers (states, corporations, AI) with biosphere integrity and human flourishing, averting collapse via six-level ethical hierarchy and blind mechanism corrections. NHP transforms fragmented disciplines into a progressive, consensus-capable framework grounded in natural laws—addressing root causes of crises (superpower misalignment, blind cultural evolution) and prescribing alignment for sustainable global civilization. This completes the series: philosophy, social sciences, and humanities converge on natural science as the sole reliable path forward. This concluding preprint solidifies NHP as humanity's comprehensive self-understanding system: from transgression to superposition, from blind mechanisms to deliberate realignment—offering not speculation, but falsifiable science for our species' survival.
