Who Grants Logic the Right to Judge Reality? Strong Causality, Strong Logical Conceivability, and the Ontological Possibility of Philosophical Zombies

What gives logic the authority to determine what reality can and cannot be? This paper introduces Strong Causality as a theoretical framework for examining the conditions under which causal-logical structures emerge, stabilize, and acquire the authority to delimit ontological possibility. Its central target is the transition from strong logical conceivability to metaphysical possibility, particularly in David Chalmers’s philosophical zombie argument. The paper begins with a recursive conception of reality in which present states depend on prior states and environmental conditions, while feedback mechanisms reinforce relatively stable patterns. Such patterns may support enduring concepts of objects, properties, identity, causation, and logical inference without thereby establishing that these structures possess unconditional or timeless authority. The proposed Principle of Conceptual Inclination further suggests that inherited concepts, linguistic practices, and repeated patterns of reasoning shape what appears intelligible, coherent, and self-evident within a given conceptual framework. This analysis leads to two connected questions. First, can an ontological framework adequately explain the conditions under which its own categories and standards of judgment apply? Second, even if a philosophical zombie world is strongly logically conceivable, what justifies the inference from that conceivability to its ontological possibility? To investigate these questions, the paper develops the thought experiment of an Ontological Black Swan: a limit case in which the conditions supporting familiar forms of object identification, causal explanation, and logical assessment can no longer simply be taken for granted. This thought experiment motivates what the paper calls the Ontological Hard Problem—the problem of explaining the applicability conditions and limits of the very structures through which ontology articulates and evaluates reality. Strong Causality does not merely claim that everything has a cause, nor does it assume that the philosophical zombie is impossible. Instead, it redirects attention toward the formation, stability, and limits of the causal-logical frameworks through which possibility is conceived and assessed. Its challenge to Chalmers is therefore methodological and modal: strong logical conceivability may establish that a scenario is intelligible under a given framework, but the authority of the transition from intelligibility to mind-independent ontological possibility requires further justification. The paper concludes by identifying a reflexive task for modal philosophy: to explain not only what a framework permits us to conceive, but also why that framework is entitled to determine the boundaries of the possible.
