Mackie's Internalisms

Abstract

John Mackie is famous for defending an error theory about moral judgments. His main arguments for this controversial view are based on relativity and on queerness. He calls the argument from queerness “more important” and “more generally applicable” (1977, p. 38), and then he divides this argument into metaphysical and epistemological parts. I subdivide the metaphysical part further into an argument from internalism and an argument from supervenience. This Chapter explores part of Mackie's argument from internalism.
