This book is excellent. The fundamental proposal is elegant and powerful, and the writing is beautiful. (How often does one get to say that about work in contemporary agency theory?) King identifies a core notion, "basic agency," and shows how we can build out from this single, shared element to accounts of a wide range of different kinds of responsibility (not limited to moral). His analysis draws attention to the unity of agency and responsibility, so to speak. The book is admirable in defending a striking and bold hypothesis that illuminates various issues in the contemporary debates, without getting bogged down in them. Highly recommended!
