Hardcover. UK, Oxford University Press , 1st, 1968, Book: Very Good, Dust Jacket: Good, Hardcover, blue cloth with gilt lettering on spine, in a lightly worn rose-color dust jacket with fading to spine, 166 pages. Arthur Prior (1914-1969) undertook pioneering work in intensional logic at a time when modality and intensional concepts in general were under attack. He invented tense logic and was principal theoretician of the movement to apply modal syntax to the formalization of a wide variety of phenomena. Prior and Carew Meredith devised a version of the possible worlds semantics several years before Saul Kripke published his first paper on the topic. An iconoclast and a resourceful innovator, Prior inspired many to undertake work in intensional logic. It was the extra-symbolic world that mattered to Prior, not the formal results per se. Prior was the founding father of logic in New Zealand and also a driving force behind the renaissance in British logic from 1956. Name on front fly leaf, otherwise clean.
