 Various objections to the coherence or usefulness of rigidity have been put forward by specialists in the philosophy of language, though the objections do not seem to have done much to damage the widespread appeal of rigidity, which is commonly taken for granted in mainstream literature from various areas of philosophy. (Whether your typical philosopher is entitled to embrace rigidity is another matter: so there is a case for saying, on grounds independent from the foregoing objections, that rigidity and the necessity accompanying it stand or fall with a robust version of the analytic-synthetic distinction (see   note 4).  If that case is solid, then either popular Quinean antagonism toward analyticity should prompt the rejection of rigidity or else the appeal of rigidity should prompt the rejection of the familiar antagonism toward analyticity.) What resistance to rigidity there is may be addressed in general terms first, in order to save for its own subsection  (§4.2)  treatment of objections specifically directed at the application of rigidity to terms for properties, which are especially contended.
