. . . Taylor’s book is a richly informative and admirable attempt to delineate “the full shape of the human linguistic capacity” (as its subtitle has it). More than that, it affords a model of what it is to be a genuine philosopher: at an age when most philosophers have either given up altogether or else fallen into dogmatically repeating views that they have long since held, Taylor continues an open-minded search for the right answers, drawing not only on the older literature from philosophy and several other disciplines that he has long since mastered but also on a wealth of newer literature from an equally wide range of sources.
