This book is intended as an exposition of a particular theory of time in the sense of an interrelated set of attempted solutions to philosophical problems about it. Generally speaking there are two views about time held by philosophers and some scientists interested in philosophical issues. The first called the A-theory (after McTaggart's expression A-determinations for the properties of being past, present or future) is often thought to be closer to our commonsense view of time or to the concept of time presupposed by ordinary language. It includes at least the following theses, (a) Logic...

In connection with the "Philosophy of Science" research program conducted by the Deutsche Forschungsgemeinschaft a colloquium was held in Munich from 18th to 20th May 1919. This covered basic structures of physical theories, the main emphasis being on the interrelation of space, time and mechanics. The present volume contains contributions and the results of the discussions. The papers are given here in the same order of presentation as at the meeting. The development of these "basic structures of physical theories" involved diverging trends arising from different starting points in...

This volume constitutes the Proceedings of a workshop on formal seman tics of natural languages which was held in Tiibingen from the 1st to the 3rd of December 1977. Its main body consists of revised versions of most of the papers presented on that occasion. Three supplementary papers (those by Gabbay and Sma by) are included because they seem to be of particular interest in their respective fields. The area covered by the work of scholars engaged in philosophical logic and the formal analysis of natural languages testifies to the live liness in those disciplines. It would have been...

1. IMPORTANCE OF THE SUBJECT In 1900, in A Critical Exposition of the Philosophy of Leihniz, Russell made the following assertion: "That all sound philosophy should begin with an analysis of propositions is a truth too evident, perhaps, to demand a proof." 1 Forty years later, the interest aroused by this notion had not decreased. C. J. Ducasse wrote in the Journal of Philosophy: "There is perhaps no question more basic for the theory of knowledge than that of the nature of 2 propositions and their relations to judgments, sentences, facts and inferences." Today, the great number of...

Among the several dozens of symposia held on the occasion of the quincentennial of U ppsala University, there was included one symposium devoted to the theme of 'Philosophy and Grammar'. A selection of the most important papers delivered at this symposium have been collected in this volume. The papers need no introduction, but the inclusion of two of them in this collection requires a brief comment. First, the paper by von Wright, although not directly concerned with the central topic of the symposium, has been included because it was the terminating speech of the six parallel symposia...

Uniqueness of style versus plurality of styles: in terms of these aesthetic categories one of the most important differences between the recent past and the present can be described. This difference manifests itself in all spheres of life - in fashion, in everyday life, in the arts, in science. What is of interest for my purposes in this book are its manifestations in the processes of con cept formation as they occur in the humanities, broadly conceived. Here the following methodological approaches seem to dominate the scene. 1. A tendency to apply semiotic concepts in various fields of...

The two volumes to which this is a preface consist of the Proceedings of the Second International Conference on History and Philosophy of Science. The Conference was organized by the Joint Commission of the International Union of History and Philosophy of Science (IUHPS) of the IUHPS, the Italian Society for Logic and under the auspices Philosophy of Science, and the Domus Galilaeana of Pisa, headed by Professor Vincenzo Cappelletti. Domus GaIilaeana also served as the host institution, with some help from the University of Pisa. The Conference took place in Pisa, Italy, on September 4-8,...

Logic has attained in our century a development incomparably greater than in any past age of its long history, and this has led to such an enrichment and proliferation of its aspects, that the problem of some kind of unified recom prehension of this discipline seems nowadays unavoidable. This splitting into several subdomains is the natural consequence of the fact that Logic has intended to adopt in our century the status of a science. This always implies that the general optics, under which a certain set of problems used to be con sidered, breaks into a lot of specialized sectors of inquiry,...

Logical empiricism - not to be confused with logical positivism (see pp. 40-44) - is a movement which has left an indelible mark on twentieth century philosophy; Hans Reichenbach (1891-1953) was one of its found ers and one of its most productive advocates. His sudden and untimely death in 1953 halted his work when he was at the height of his intellectual powers; nevertheless, he bequeathed to us a handsome philosophical inheritance. At the present time, twenty-five years later, we can survey our heritage and see to what extent we have been enriched. The present collection of essays...

Simple seeing. Plain talking. Language in use and persons in action. These are among the themes of Virgil Aldrich's writings, from the 1930's onward. Throughout these years, he has been an explorer of conceptual geography: not as a foreign visitor studying an alien land, but close up 'in the language in which we live, move, and have our being'. This is his work. It is clear to those who know him best that he also has fun at it. Yet, in the terms of his oft-cited distinction, it is equally clear that he is to be counted not among the funsters of philosophy, but among its most committed...
