Broad study on cognitive science that is unapologetic about its range of sources, from philosophy (Merleau-Ponty to Nietzsche) to colour theory (including art) to artificial intelligence to Buddhist meditation practices to neurology to social criticism (and the idea of commonage). Somehow the authors pull together a book that is not only interesting but also very engaging and legible. Great insights, a little dated, but still relevant for the breadth of research that went into the book.
