Broad on mental events and epiphenomenalism

Abstract

The relationship between mind and body involves the question of whether mental events are ontologically fundamental or contingent upon an underlying substance. Treating mental events as the primary constituents of consciousness permits a “bundle theory” of the mind, which replaces the concept of a “Pure Ego” with a structure of interrelated experiences. Epiphenomenalism emerges as a plausible, albeit problematic, hypothesis within this framework, asserting that mental events are produced by physiological processes but possess no causal influence over the physical world. However, this position necessitates a complex distinction between horizontal physical causation and vertical production of the mental, a distinction that lacks clear empirical or logical justification. Denying the causal efficacy of mental events creates a profound conflict with common-sense perceptions of human agency, wherein thoughts and intentions appear to direct bodily movements. This creates a reflexive paradox: the very process of debating the status of mental events presupposes the efficacy of the thought required to conduct the argument. Furthermore, an epiphenomenalist account struggles to accommodate the mechanisms of introspection and prehension, as these concepts traditionally imply a subject to whom events occur. Ultimately, while epiphenomenalism offers a scientifically economical model, its rejection of interactionist common sense relies more on aesthetic preferences for theoretical simplicity than on definitive empirical refutation. – AI-generated abstract.
