This important new book develops a new concept of autonomy. The notion of autonomy has emerged as central to contemporary moral and political philosophy, particularly in the area of applied ethics. professor Dworkin examines the nature and value of autonomy and uses the concept to analyse various practical moral issues such as proxy consent in the medical context, paternalism, and entrapment by law enforcement officials.'Issues about autonomy are fundamental in ethics. Dworkin provides an excellent introduction to those issues, and I do not know of any book length discussion of a comparable sort.' Gilbert Harman, Princeton University
