Dale Jacquette argues that contemporary philosophy labours under a number of historically inherited delusions about the nature of logic and the philosophical significance of certain formal properties of specific types of logical constructions. He exposes some of the key misconceptions about formal symbolic logic and its relation to thought, language and the world, i.e. he clears the ground of some very well-entrenched philosophical doctrines about the nature of logic, including some of the most fundamental seldom-questioned parts of elementary propositional and predicate-quantificational logic. Having presented difficulties for conventional ways of thinking about truth functionality, the metaphysics of reference and predication, the role of a concept of truth in a theory of meaning, among others, Jacquette proceeds to reshape the network of ideas about traditional logic that philosophy has acquired along with modern logic itself.In so doing Jacquette is able to offer a new perspective from this revisionary standpoint of a number of outstanding problems in logic and philosophy of logic. Logical puzzles and paradoxes are shown to be symptomatic of deep incongruities in our use of language, and that these in complex ways are indicative in turn of the surmountable limitations of thought at a given stage of cultural development.
