'The authors provide a systematic treatment of the role of inconsistency in linguistic usage. Their discussion is thoroughly grounded in the literature of inconsistency in contemporary linguistics, semantics, logic, rhetoric, and philosophy. Their innovative perspectives and proposed solutions to problems will interest everyone who works in this challenging area.'
