Work in Progress

My dissertation explores the question of which units of agency should be of relevance to ethics. I argue that obligations and normative reasons for action are possessed not only by individual persons, but also by larger units, namely groups, and by smaller units, namely the temporal parts of persons. I also defend views about how obligations and reasons for action possessed at different units of agency interact: for example, about when I have reason to do my part in what the group ought to do, and about whether there can be irresolvable conflicts between individual and collective obligations.
