Abstract

Thus ethical theory has been involved in a double controversy, the general controversy between naturalism and supernaturalism, and a more special one between naturalism, intuitionism, and non-cognitivism. These two debates have been variously mingled. Naturalists in the one sense have not always been naturalists in the other. Some naturalists in the broad sense have also been naturalists in the narrower, but some of them have been intuitionists, and many of them, especially recently, have been non-cognitivists. Again, supernaturalists have sometimes been intuitionists, sometimes non-cognitivists, and sometimes naturalists.
