This book is dedicated to the memory of Professor Henryk Mehlberg, primarily because I want to recall his name to readers in the West; for, although Professor Mehlberg was the foremost Polish philosopher in the field of philosophy of time-in that version which is related to twentieth century physics-his fundamental work concerning time was published in English 43 years after its original publication (cf. Mehlberg, 1980). I am deeply indebted to Henryk Mehlberg. For two years after the Second World War, I was his student at Wroclaw University (where he lectured on philosophy and mathematical...

The general view of Russell's work amongst philosophers has been that repeat edly, during his long and distinguished career, crucial changes of mind on fun damental points were significant enough to cause him to successively adopt a diversity of radically new philosophical positions. Thus Russell is seen to have embraced and then abandoned, amongst others, neo-Hegelianism, Platonic re alism, phenomenalism and logical atomism, before settling finally on a form of neutral monism that philosophers have generally found to be incredible. This view of Russell is captured in C. D. Broad's famous...

The first Symposium consisted of three people in a cafe in Warsaw in 1973. Since then, meetings have grown in size and have been held in Leyden, Copenhagen, Nijmegen, Rome, Oxford, Poitiers and Freiburg- am-Breisgau. The ninth Symposium was held in St Andrews in June 1990, with 57 participants who listened to addresses by 28 speakers. It was very fitting that Scotland's oldest university, founded in the heyday of medievalleaming in 1411, should have been given the chance to bring together scholars from all over Europe and beyond to present their researches on the glorious past of scholastic...

JOHN WISDOM AND THE BREADTH OF PHILOSOPHY hham Dhman 1. THE ESSAYS IN THIS VOLUME The essays following the two pieces by John Wisdom have all been written by philosophers who are former students or friends of Wisdom or who have a high regard for his work. Their contributions were all written with him in mind and to be discussed at a conference honouring his work. This conference was held in August 1983 at Trinity College, Cambridge, of which Wisdom has been a fellow since 1935. Wisdom is a master of discursive reasoning and one of his distinctive contributions in philosophy has been to...

Philosophers of science frequently bemoan (or cheer) the fact that today, with the supposed collapse of logical empiricism, there are now;;10 grand systems. However, although this mayor may not be true, and if true mayor may not be a cause for delight, no one should conclude that the philosophy of science has ground to a halt, its problems exhausted and its practioners dispirited. In fact, in this post Kuhnian age the subject has never been more alive, as we work with enthusiasm on special topics, historical and conceptual. And no topic has grown and thrived quite like the philosophy of...

Tadeusz Kotarbinski is one of towering figures in contemporary Polish philosophy. He was a great thinker, a great teacher, a great organizer of philosophical and scientific life (he was, among others, the rector of the Uni versi ty of t6dz, the president of the Polish Academy of Sciences, and the president of the International Institute of Philosophy), and, last but not least, a great moral authority. He died at the age of 96 on October 3, 1981. Kotarbinski was active in almost all branches of philosophy. He made many significant contributions to logic, semantics, ontology, epistemology,...

Roman Ingarden's very extensive philosophical work in metaphysics, ontology, epistemology, and aesthetics con tinues to attract increasing attention both in Poland and in North America. Further work left uncompleted at his death is appearing. Major bibliographies of his work as well as of studies about his work are now in print. Ingar den's scattered articles on various questions in philosophy are being collected. And conferences devoted to his work are now held regularly. These diverse activities might suggest a similar diver sity in Ingarden's philosophical legacy. But such a sugges tion...
