This text tackles one of the most difficult areas in philosophy. It surveys all of the major philosophical theories of truth, presenting the crux of the issues involved at a level accessible to non-experts, yet in a manner sufficiently detailed and original to be of value to professional scholars. Included are discussions of such theories as the correspondence, coherence, pragmatic, semantic, performative, redundancy, appraisal and truth-as-justification theories. Also covered are the liar paradox, three-valued logic, Field's critique of Tarski, satisfaction and recursion, as well as how theories of justification, properly understood, differ from theories of truth.
