This chapter considers objections to the fuzzy view of vagueness in particular, and to degree-theoretic treatments of vagueness in general. These objections are that the very idea of truth coming in degrees is in some way confused or mistaken; that fuzzy theory involves an objectionable violation of classical logic; that degrees of truth cannot be integrated with key developments elsewhere in philosophy of language, outside the study of vagueness; that degree theories which treat the logical connectives as truth functions cannot account for ordinary usage of, and/or intuitions about the truth and/or assertibility of, compound sentences about borderline cases; and that denying bivalence leads to contradiction.
Keywords: classical logic, assertibility, truth functionality, bivalence, fuzzy logic
