Abstract

These books are telling examples which demonstrate that at least some contemporary philosophers have again attained the high level of ‘scholastic’ sophistication which was typical of men like Aristotle, Diodorus Cronus, Chrysippus, Aquinas or Ockham. It can even be said that in an important respect this classical level has been surpassed: Prior’s presentation of the different calculi of tense logic in Past, Present and Future documents the recent progress of symbolic formalization in a domain where the classics had to struggle laboriously with Greek or Latin sentences.
