Lawrence Haworth's book, Autonomy, discusses “Autonomy as a Psychological Idea”, and “Autonomy as a Normative Idea”. Part 1 discusses autonomy in relation to rationality, agency, and responsibility, defends it against Skinnerian sceptics, and outlines a theory of autonomous decision-making and the autonomous task environment. Haworth's conception of autonomy integrates and builds on the concepts of S. I. Benn, G. Dworkin, H. Frankfurt, and R. W. White. Part 2 centres on social/political theory, and not, despite the book's subtitle, on ethics as such. Haworth argues that only autonomy, and not liberty or happiness, is an intrinsic (non-moral) value, and fundamental right. His “autonomist” theory of liberty rights, a form of revisionary liberalism derived from the later idealists, is opposed to the classical liberal/libertarian theory. The arguments prompt a re-examination of the role of autonomy in the arguments for liberty (and happiness), but do not, in my view, make a persuasive case for “autonomism” against classical liberalism (hereafter liberalism). The book is chiefly noteworthy for its success in covering many important topics connected with autonomy, in an impressively short space, and in an always clear and often very insightful way.
