 The second line of inquiry concerns the set of possible comparative relations that can obtain between two items. The small improvement argument for the incomparability of the musical career and the legal career in Raz’s example assumes what Chang calls the “trichotomy thesis.” The trichotomy thesis holds that if two items can be compared in terms of some value or set of values, then the two items are related by one of the standard trichotomy of comparative relations, “better than,” “worse than,” or “equally good” (2002b, 660). A number of authors have argued that these three comparative relations do not exhaust the space of comparative relations. If they are correct, the musical career and the legal career may, in fact, be comparable.
