Gilbert Harman on Relativism
"Is There a Single True Morality?" in Morality, Reason and Truth, ed. David Copp and David Zimmerman (Rowmand and Allanheld, 1984).Like many people, I have always been instinctively a moral relativist. As far back as I can remember, it has always seemed to be obvious that the dictates of morality arise from some sort of convention or understanding among people, that different people arrive at different understandings, and that there are no basic moral demands that apply to
everyone. This seemed so obvious to me I assumed it was everyone’s instinctive view, or at least everyone who gave the matter any thought in this day and age.
