Abstract
In this paper, I will critically consider Clark and Chalmers’ hypothesis of the «extended mind» in order to sketch a possible phenomenological account of active externalism, by following three steps: I will consider Clark and Chalmers’ hypothesis within the broader context of the so-called «physical symbol system hypothesis» theorized by Herbert A. Simon; I will connect the problem of the «extended mind» to that of the «extended self», with particular regard to the context of digitalization; I will take into account an explanatory dimension that has been fundamentally underrated by externalist theories: the dimension of the human body and its relationship to mind, which I understand from a phenomenological perspective. My ultimate goal is to show how phenomenology could provide the missing theoretical framework to develop a more complex and comprehensive theory of the extended self.
