 In what follows I will be as neutral as possible between different theoretical approaches to morality, and will focus on the debate between monists and pluralists. Monists claim that there is only one ultimate value.  Pluralists argue that there really are several different values, and that these values are not reducible to each other or to a supervalue. Monism has the advantage of relative simplicity: once it has been determined what the supervalue is (whether we think of the super value in terms of the goods approach or any other approach) much of the hard work has been done. On the other hand, monism may be too simple: it may not capture the real texture of our ethical lives. However, pluralism faces the difficulty of explaining how different fundamental values relate to each other, and how they can be compared.
