Professor Buss is interested in issues at the intersection of metaphysics and ethics. She is the author of articles on autonomy, moral responsibility, practical rationality, and respect for persons.   In her work, she has developed accounts of weakness of will, our moral obligations to the needy, the rationality of our concern for our own happiness, the relationship between intentional action and evaluative commitments, the relevance of childhood deprivation to assignments of blame, the moral importance of etiquette, and the metaphysical significance of illness.  Her current projects address the normative significance of formal principles of practical rationality, the nature of reasons for action, the will's contribution to action, and the moral implications of certain basic human capacities.
