An article on the question whether it is justified to prohibit consensual harm to others whilst not prohibiting the same harm if it is done to oneself.
Work on this article was supported by a fellowship from the National Endowment for the Humanities, and by a sabbatical leave from the College of Literature, Science, and the Arts, University of Michigan. An earlier and very different version was presented to the philosophy department and the Center for Ethics and Humanities in the Life Sciences at Michigan State University. I received helpful comments on that version from Elizabeth Anderson and Stephen Darwall, both of whom have also contributed significantly to my thinking on this subject through their published work.
