Abstract

For almost the past three decades the model of autonomy which has dominated philosophical discussion of this concept has been the "hierarchical" model, which has been independently developed and defended by Harry Frankfurt, Gerald Dworkin and John Christman, and which is primarily concerned with what makes a person autonomous with respect to her first-order desires. It is argued that all versions of the hierarchical model of personal autonomy are based upon a theoretical mistake, and so should be rejected. This mistake is to focus upon the person's attitude towards the desire in question. Such attitude-based approaches will be mistaken because it is always possible to raise the question as to whether the person is autonomous with respect to this attitude itself. With this rejection of the hierarchical analyses of autonomy in hand it is argued that a person is autonomous with respect to her first-order desires to the extent that she has critically reflected upon the beliefs which lead her to have them. This belief-based approach to autonomy enjoys several advantages over its attitudebased rivals. It avoids all of the problems that are faced by the attitude-based models offered by Frankfurt et al., and it is also able to recognize a richer taxonomy of desire than they are. Moreover, this account of autonomy is not committed to either a Humean or an anti-Humean model of motivation. ;With the defense of the belief-based model of autonomy in hand, it is then applied to three distinct debates within applied ethics; social ethics , business ethics , and medical ethics' focus on the Principle of Respect for Autonomy. This part of the dissertation concludes by observing that in all three of these particular debates it is not autonomy that is of primary concern, but well-being, subjectively understood
