ABSTRACT
Monism about well-being is the view that there is exactly one basic (prudential) good and exactly one basic (prudential) bad. Pluralism about well-being is the view that there is either more than one basic good or more than one basic bad.1 We can illustrate this distinction by contrasting hedonism and desire satisfactionism, on the one hand, with objective list theories, on the other. Hedonism and desire satisfactionism disagree about what the basic goods and bads are, but they agree about the number: they both say that there is a single basic good and a single basic bad. By contrast, objective list theories-or at least the paradigmatic ones-posit either a plurality of basic goods or a plurality of basic bads. Parfit, for example, considers an objective list theory on which “moral goodness, rational activity, . . . and the awareness of true beauty” are all basic goods (Parfit 1984: 499).
