Abstract

This chapter sketches an argument for moral non‐naturalism. The argument begins by noting that naturalist positions must be reductionist. It then canvasses two prominent defenses of reductionist naturalism: Frank Jackson's and Mark Schroeder's. Both defenses suffer from serious problems. Because they do, we have good reason to carefully consider rival realist positions, such as non‐naturalism. When we do, we find that some moral facts, such as the fundamental moral standards, do not bear the marks of the natural. This provides prima facie reason to hold that they are as non‐naturalists believe.
