Upshot: Self and Other takes on an ambitious task of articulating an account of selfhood that would do justice both to the experiential and the intersubjectively constructed aspect of the self. We claim that Zahavi argues convincingly against the possibility of reducing the former to the latter, but that he needs to develop his position further in order to offer a convincing account of their interconnectedness.

Open peer commentary on the article “A Moving Boundary, a Plastic Core: A Contribution to the Third Wave of Extended-Mind Research” by Timotej Prosen. Abstract: We explore both some novel claims made by Prosen’s account of plastic cores and some overlaps between his and other accounts of third-wave extended mind. In the first instance we discuss whether the Markov blanket formalism should be regarded as incompatible with a third-wave extended view. Secondly, we discuss whether Prosen’s proposal (...) of a plastic core quite meets the radical departure of the third wave from organism-centeredness - or whether Prosen’s contribution might be more aptly considered as a compromise between second- and third-wave extended mind.

Open peer commentary on the article “A Moving Boundary, a Plastic Core: A Contribution to the Third Wave of Extended-Mind Research” by Timotej Prosen. Abstract: We argue that the free-energy principle (FEP) can indeed be used to articulate a conception of the boundaries of cognitive systems that meets the desiderata of third-wave extended-mind research. We point out that Markov blankets under the FEP definitionally constitute the means through which internal and external states are coupled, and so do not (...) isolate systems from their environment. We argue that the nested, multiscale boundaries of the FEP formulation are indeed plastic and open to re-negotiation. Finally, we appeal to the formulation of niche construction under the FEP to argue that the extension of cognitive boundaries in this formulation is both synchronic and diachronic. (shrink)
