Another Argument For Non-naturalism

Moore also introduced what is called the Open Question Argument, a position he later rejected.

Suppose a definition of "good" is "pleasure-causing." In other words, if something is good, it causes pleasure; if it causes pleasure, then it is, by definition, good. Moore asserted, however, that we could always ask, "But are pleasure-causing things good?" This would always be an open question. There is no foregone conclusion that, indeed, pleasure-causing things are good. In his initial argument, Moore concluded that any similar definition of goodness could be criticized in the same way.
