I read on Dave Chalmers’ weblog that he’s written the preface to Andy Clark’s forthcoming Supersizing the Mind: Embodiment, Action, and Cognitive Extension. It’s very exciting news that a) there is a new book by Clark, perhaps the best stylist around and that b) Chalmers (and Clark) have returned to considering their thesis of active externalism ten years after the publication of their classic paper, a punchy paper that launched a cottage industry. Clark’s book will no doubt be required reading by all those participating in the themed issue of The Journal of Mind and Behavior I’m editing on the extended mind thesis.
