Hegel and the extended mind

We examine the theory of the extended mind, and especially the concept of the “parity principle” (Clark and Chalmers in Analysis 58.1:7–19, 1998), in light of Hegel’s notion of objective spirit. This unusual combination of theories raises the question of how far one can extend the notion of extended mind and whether cognitive processing can supervene on the operations of social practices and institutions. We raise some questions about putting this research to critical use.
