I'm a philosopher. Last year I was honored to serve as President of the American Philosophical Association (Central Division).
Most of my work has been in metaethics, which is that area of philosophy that focuses on questions about the status (rather than the content) of morality. Such questions include:
Is morality created by human beings, or is it in some way objective?
How do we gain moral knowledge?
Is there always excellent reason to obey moral requirements? Are immoral people necessarily irrational?
How can moral values exist in a world governed by scientific laws?
My interest in the field led me to inaugurate the annual Madison Metaethics Workshop (a.k.a. MadMeta). I also edit a book series on these topics, Oxford Studies in Metaethics, whose contents are based largely on papers given at each workshop. (See link below.) Because one can never get enough metaethics, I also administer the Marc Sanders Prize in Metaethics for Younger Scholars.
