 The problem is that the soundness of any positive conditional sorites undercuts the truth of the unconditional premise of the corresponding negative version, and vice versa. Unless one is prepared to accept a pandemic of contradictions in natural language, not all sorites can be sound. Unger (1979) and Wheeler (1979) propose a more restricted embrace. Dissatisfied with responses of types (1) and (3), one accepts the applicability and validity of classical norms of reasoning. Nonetheless, dissatisfaction with responses of type (2) considered so far—rejecting some conditional premise—leaves open the option of either rejecting the minor (unconditional) premise or accepting it and, with it, the soundness of the paradox. What is advocated is the soundness of those sorites which deny heapness, baldness, hirsuteness, richness, poverty, etc. of everything—a type (4) response—and the corresponding falsity of the unconditional premise of all respective positive variants of the argument—a type (2) response. Terms like ‘heap’, ‘bald’, ‘hirsute’, ‘rich’ and ‘poor’ apply to nothing. (For criticisms, see Williamson 1994a: Ch. 6.)
