Tense Logic : Springer : 9789027706973 : 9027706972 : 31 Dec 1976 : This monograph is designed to provide an introduction to the principal areas of tense logic. Many of the developments in this ever-growing field have been intentionally excluded to fulfill this aim. Length also dictated a choice between the alternative notations of A. N. Prior and Nicholas Rescher - two pioneers of the subject. I choose Prior's because of the syntactical parallels with the language it symbolizes and its close ties with other branches of logi­ cal theory, especially modal logic. The first chapter presents a wider view of the material than later chapters. Several lines of development are consequently not followed through the remainder of the book, most notably metric systems. Although it is import­ ant to recognize that the unadorned Prior-symbolism can be enriched in vari­ ous ways it is an advanced subject as to how to actually carry off these enrichments.
