One can often encounter an opinion that Polish scientific (or analytic) philosophy (or the Lvov-Warsaw School) deserves to be much better known than actually is. This book is thought as a response to such a claim. The papers collected in this volume are divided into two parts: Background and Influence and History and Systematics. However, there is no sharp borderline between themes which are touched in both parts. Generally speaking, all papers of the first part relate the Lvov-Warsaw School to some philosophical movements (Brentanism, phenomenology and Marxism) external to it whereas the papers collected in the second one focus on internal issues connected with the school (only Roberto Poli takes into account Brentano's views in his discussion of reism). Since the Polish school of mathematical logic is much better known than the Polish analytic philosophy we decided to omit here any treatment of the former. Thus, this collection centers on purely philosophical matters. We projected this volume not as an exhaustive panorama of Polish analytic philosophy but rather as a series of essays on particular persons or topic. As a result one can find here papers on Twardowski. Ajdukiewicz, Kotarbinski, Tarski and Lukasiewicz as well as on ethics on science, nominalism, and the methodology of psychology. We hope that this book will contribute to a better knowledge and evaluation of Polish achievements in analytic philosophy. We would like to express our gratitude to Professor Leszek Nowak, the editor-in-chief of Poznan Studies in the Philosophy of the Sciences and the Humanities, who initiated the idea of the collection and helped in its preparation.

This is a collection of some works of Polish philosophers and physicists on philosophical problems of time and spacetime. Without restricting the thematic scope of the papers, the issue conceming objectivity of time flow runs as a uniting thread through most of them. Partly it is discussed directIy, and partly the authors focus on themes which are of paramount importance for one's attitude to that question. In the first six papers the authors deal with their topics against the background of contemporary physics, its theories, its difficulties and discussed conjectures. For the paper of S. Snihur that background is provided by everyday worId-outlook, and the author discusses the problem of existence and character of the future in the light of basic principles of cIassical logic. The paper of A. P61tawski, about the views of the outstanding polish philosopher Roman Ingarden, enriches the thematic scope of the coIIection introducing into it some questions from philosophical anthropology and ethics. JERZY GOLOSZ MOTION, SPACE, TIME*. Abstract. The paper discusses the properties of spacetime we study by analyzing the phenomenon of motion. Of special interest are the spacetime symmetries. the spacetime structures and the ontological status of spacetime. These problems are considered on the grounds of the c1assical theories of motion contained in Newtonian physics, special and general theory of relativity. The controversy between an absolute and a relational conception of motion and its ontological implications are also analyzed.

The volume is a collection of essays about prominent Polish 20th century philosophers of science and scientists who were concerned with problems in the philosophy of science. The contribution made by Polish logicians, especially those from the Lvov-Warsaw School, like Łukasiewicz, Kotarbiński, Czeżowski or Ajdukiewicz, is already well known. One of the aims of the volume is to offer a broader perspective. The papers collected here are devoted to the work of such philosophers as Zawirski, Metallmann, Dąmbska, Mehlberg, Szaniawski and Giedymin as well as to the work of such scientists as Smoluchowski, Fleck, Infeld and Chyliński. The introduction to the volume, written by the editor and Jacek Jadacki, presents an overview of the history of the Polish philosophy of science from the foundation of the Cracow Academy (in 1364) to the present.

First published in 1967, Polish Analytical Philosophy presents the first comprehensive study of Polish analytical philosophy that has been written in Polish or English, traces the origin of the Polish analytical movement, it's development in the period between the World Wars, and its decline after the Second World War. The book shows that although inspired by the British movement and in close touch with the Vienna circle, Polish philosophy acquired its own distinctive character. Analytical philosophy in Poland was actively engaged in logic and language but tended rather to be interested in constructing philosophical doctrines which attempted to resolve traditional problems of ontology and epistemology. The author contrasts leading representatives of analytical philosophy in Britain and in Poland, and his study will be a valuable addition to the literature of the analytical trend in Europe.

Modern philosophy has benefited immensely from the intelligence, and sensitivity, the creative and critical energies, and the lucidity of Polish scholars. Their investigations into the logical and methodological foundations of mathematics, the physical and biological sciences, ethics and esthetics, psychology, linguistics, economics and jurisprudence, and the social science- all are marked by profound and imaginative work. To the centers of empiricist philosophy of science in Vienna, Berlin and Cambridge during the first half of this century, one always added the great school of analytic and methodol ogical studies in Warsaw and Lwow. To the world centers of Marxist theoretical practice in Berlin, Moscow, Paris, Rome and elsewhere, one must add the Poland of the same era, from Ludwik Krzywicki (1859-1941) onward. American socialists and economists will remember the careful work of Oscar Lange, working among us for many years and then after 1945 in Warsaw, always humane, logical, objective. In this volume, our friend and colleague, Jerzy J. Wiatr, has assembled a representative set of recent essays by Polish social scientists and philosophers. Each of these might lead the reader far beyond this book, to look into the Polish Sociological Bulletin which has been publishing Polish sociological studies in English for several decades, to study other translations of books and papers by these authors, and to reflect upon the interplay of logical, phenomenological, Marxist, empiricist and historical learning in modern Polish social understanding.

The present volume helps to understand how the collection of miscellaneous disciplines, called the science of science, came into being. One tradition goes back to the Greek thinkers and includes practically every great name in the history of philosophy, since almost all philosophers took a stand on epistemological problems. To be sure, theory of knowledge is not to be identified with theory of science. Science is a relatively new phenomenon, dating from modern times. It is a source of knowledge, the main source (in our type of culture), but certainly not the only one. Also, epistemology deals with questions rather far removed from the practice of science. The nature of truth; the sources of knowledge; the limits of knowledge. Many people claim to understand science without being able to solve these perennial problems. What we call today the science of science is not concerned with, say, the Kantian question how synthetic a priori truths are possible. However, the influence of the philosophical heritage is still felt in present day metascientific thOUght. Philosophy of science does exist, although in a form very different from classical epis temology. It has developed (under that name) into general metho dology of science, which roughly means: analysis of scientific theories and analysis of their validation. In both cases, mathematical and logical tools playa great role. Scientific theories are analyzed by means of modern semantics (theory of models). Their valida tion is reconstructed in terms of probability and decision theory.
