 Although Shapelessness is a general issue about evaluative concepts, its bearing on thick concepts is worth noting. Suppose an outsider could anticipate insiders’ use of an evaluative term in new cases by using similarities between old cases and new cases to infer whether the evaluative term applies in the new cases. Shapelessness entails that such similarities would have to be evaluative. If so, Descriptive Equivalence is false. Conversely, insofar as the extensions of evaluative terms can be mastered on the basis of non-evaluative similarities, Shapelessness is false. The way thick terms involve non-evaluative description may be thought to make them a particularly suitable test case for these general issues about evaluative concepts. But note, finally, that thick concepts do so only if their evaluative aspects are somehow built into them, such as perhaps as a matter of meaning. The commitment here is to:
