Beyond the Parity Principle

Clark and Chalmers’ extended mind theory and its parity principle constitute a foundational reference in the philosophical debate on the relationship between mind and technological artefacts. This article argues that generative artificial intelligence represents a historically unprecedented artefact that the parity principle is structurally unable to describe, and that the framework of Participated Agency (PA) offers superior explanatory power for two specific reasons: the inversion of the causal direction between subject and artefact, and the distinction between cognitive functions originally internal and subsequently externalized, on the one hand, and consequences produced on the agent by the artefact, on the other. The article further shows how the subdivision of the algorithmic mediation plane into three levels—the visibility plane, the ambition plane, and the emotional plane—provides an explanatory granularity that is ontologically irreducible to the extended mind framework. The paper concludes by arguing that PA is not merely an alternative to the extended mind but its genuine supersession, in the precise sense of a superior explanatory capacity with respect to the specific phenomena of contemporary generative AI.
