From Causal Production to Structural Constraint: Explanatory Roles, Emergence, and Ontological Stability

This book examines a recurring pattern of explanatory contraction in contemporary philosophy of science: in debates over emergence, higher-level explanation, mechanistic analysis, quantum entanglement, and anomalous phenomena, explanation is often tacitly understood as the disclosure of a process of causal production. The present work does not deny the central importance of causal explanation. What it rejects is the elevation of causal explanation into the only model of explanation. It begins by diagnosing this tendency as a form of explanatory monism, and distinguishes within it three levels: evaluative monism, role monism, and competitive monism. It then proposes a multi-role view of explanation, according to which explanation comprises three irreducible roles: causal production, structural constraint, and permissibility. Causal production answers how a result comes about; structural constraint answers which paths are limited or excluded; permissibility answers which patterns can stably exist under given constraints. On this basis, the book reexamines emergence, higher-level explanation, non-predictive frameworks, quantum entanglement, and unknown phenomena, arguing that many traditional difficulties do not in fact require the postulation of new causal powers or ontological inflation, but instead arise from explanatory miswriting between distinct explanatory roles. Finally, it further argues that when structural constraint and permissibility display stability, indispensability, counterfactual constraint, and realizational support across multiple theoretical contexts, they should not be reduced to mere pragmatic convenience, but should instead support a restrained layered structural realism. This book adopts “restrained layered structural realism” as the principal name of that position. “Radiance-Will Ontology” is retained only as a rhetorical secondary designation, meant to characterize the stable manifestation and organizational directionality of reality across different scales of organization. The aim of this book is to show that theoretical maturity does not come from forcing all forms of explanation into a single model of production, but from rigorously differentiating among explanatory roles, methodological standards, and ontological commitments.
