 The other definition requires that we introduce, prior to “good” and “bad”, a set of neutral propositions. Goodness is predicated of everything that is better than some neutral proposition, and badness of everything that is worse than some neutral proposition. The best-known variant of this approach was proposed by Chisholm and Sosa (1966). According to these authors, a state of affairs is indifferent if and only if it is neither better nor worse than its negation. Furthermore, a state of affairs is good if and only if it is better than some indifferent state of affairs, and bad if and only if some indifferent state of affairs is better than it.
