Markus Gabriel offers an account of the human self that overcomes the deadlocks inherent in the standard positions of contemporary philosophy of mind. His view, Neo-Existentialism, is thoroughly anti-naturalist in that it repudiates any theory according to which the ensemble of our best natural-scientific knowledge is able to account fully for human mindedness. Instead, he shows that human mindedness consists in an open-ended proliferation of mentalistic vocabularies. Gabriel's argument is challenged in this volume by Charles Taylor, Andrea Kern and Jocelyn Benoist.
