Surveys and extens work that has been done in the past two years on 'tense logic' and is a sequel to the author's book, Time and Modality.

Divided into two parts, the first concentrates on the logical properties of propositions, their relation to facts and sentences, and the parallel objects of commands and questions. The second part examines theories of intentionality and discusses the relationship between different theories of naming and different accounts of belief.

The relationship between formal logic and general philosophy is discussed under headings such as A Re-examination of Our Tense-Logical Postulates, Modal Logic in the Style of Frege, and Intentional Logic and Indeterminism.

This is a revised and expanded edition of a seminal work in the logic and philosophy of time, originally published in 1968. Arthur N. Prior (1914-1969) was the founding father of temporal logic, and his book offers an excellent introduction to the fundamental questions in the field. Several important papers have been added to the original selection, as well as a comprehensive bibliography of Prior's work and an illuminating interview with his widow, Mary Prior. In addition, the Polish logic which (...) made Prior's writings difficult for many readers has been replaced by standard logical notation. This new edition will secure the classic status of the book.

This book was designed primarily as a textbook; though the author hopes that it will prove to be of interests to others beside logic students. Part I of this book covers the fundamentals of the subject the propositional calculus and the theory of quantification. Part II deals with the traditional formal logic and with the developments which have taken that as their starting-point. Part III deals with modal, three-valued, and extensional systems.

This is the text of The Lindley Lecture for 1962, given by Arthur N. Prior (1914-1969).

This book discusses and aims to clarify the issue of describing conduct and character as ‘good’ or ‘bad’, or as ‘right’ or ‘wrong’. The book states that one of the main factors that have made this issue obscure is the illusion of some anti-naturalists that purely logical considerations can settle it. It clearly defines the limitations of the discussions: it is not concerned with the ‘other things’ people use to define conduct and character. The book attempts to consider the issue (...) from the purely logician point of view and suggests to the naturalists and anti-naturalists how their positions may be freed from logical faults. The book also introduces the ‘logic of ethics’, which is not a special kind or branch of logic, but rather an application of it. (shrink)

Particular attention has been paid in the present century to the question as to whether a man's duty is to do what is actually right, i.e. what his situation actually demands of him, or what he thinks is right. Mr. Carritt has pointed out that the former possibility bifurcates—a man's duty may be to do what is actually demanded by his actual situation, or what is actually demanded by what he believes to be his situation. I do not propose in (...) the present paper to carry this discussion any further, but rather to consider how it has been carried on in the past, as there seems to be a little confusion on this point.
