Ethical Relativism

Answer the following essay question:
What is the difference between Ethical Relativism and “traditional” notions of morality? Explain and evaluate the basic arguments – diversity, tolerance, non-resolvability — offered for relativism, and the criticisms offered against these reasons. Explain moral subjectivism and moral emotivism, and how Moore’s “open question” argument criticizes these positions. How does Hume’s discussion of skeptical doubt apply to this issue? What difference does it make for personal and public conduct if we embrace one position or the other?
