Rawls, Truth, and Minimalism

The expressivist theory in metaethics has a historical lineage dating back to the work of the great philosopher David Hume. Among the major metaethical alternatives to expressivism are constructivist theories, theories that have an origin in the work of another great philosopher, Immanuel Kant. One of the best-known and most influential recent formulations of such a view is due to John Rawls. There has been a great deal of discussion of the relationship between expressivism and deflationary theories of truth. In stark contrast, there has been very little discussion of the relationship between constructivist theories and deflationary theories of truth. I argue that Rawlsian constructivists should adopt a minimalist theory of truth.
