Abstract
Some philosophers hold that sentences with the word good have a uniform form. On this view, many of the apparent syntactic and semantic differences between (say) That is a good knife, Xavier is good with children and It is good to have pets are illusory. A difficulty in evaluating uniformity theses is that they are often not formulated in a linguistically precise way. I provide an interpretation where uniformity theses treat good as taking the same arguments at some syntactic or semantic level. I then defend the view that the motivation for uniformity theses is weak, and I develop a strategy for opposing them. One version of this strategy is deployed, drawing on under-appreciated data about tough-adjectives. I argue that there is better motivation for alternative analyses of good, namely 'non-uniformity contextualism' and 'relativism'. The resulting picture is one where the apparent syntactic and semantic differences between good-constructions are genuine.
