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 made Prior's writings difficult for many readers has been replaced by standard logical notation.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 is the text of The Lindley Lecture for 1962, given by Arthur N. Prior (1914-1969).

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.

Dans Objets de pensée, Arthur Prior a condensé un certain nombre de thèmes directeurs de sa philosophie autour de deux centres d’intérêt : “Ce que nous pensons” et “Ce sur quoi nous pensons”. Le terme d’objet de pensée peut en effet désigner soit le contenu des représentations que nous formons, soit l’objet de notre pensée. Dans le premier cas, il s’agit de déterminer la nature des relations que le contenu de nos représentations entretient d’un côté avec les faits, de l’autre (...) avec les énoncés. La seconde partie du livre est entièrement consacrée aux attitudes intentionnelles. Prior se préoccupe de savoir dans quelles circonstances ou à quelles conditions on peut considérer que ces attitudes, dont la croyance est ici le principal représentant, établissent une authentique relation entre deux individus.
