Most moral philosophers work under the assumption that ordinary folk morality is committed to objectivism—that ordinary folk view morality in absolute terms. This datum serves to constrain and shape philosophical metaethics, since those working in this field feel compelled to make sense of it. In this chapter, I discuss why philosophers take on this commitment. I also outline the relevant experimental research exploring whether, and to what extent, ordinary folk think of morality in absolute terms. Finally, I turn toward a more general discussion of what implications this work may have for philosophical ethics
