This volume may be of interest for all those who wish that philosophy had a scientific character. As an adherent of the Polish Lvov-Warsaw Philosophical School, the author of this collection of papers endeavours to clarify some basic notions of epistemology, ontology and psychology of cognitive acts, such as "judgment", "existence", "being" etc. In his investigations he refrains from unnecessary rejection of common-sense knowledge but at the same time searches for suitable patterns in contemporary sciences. Regarding formal logic as a (...) fundamental tool for the precise expression and justification of thoughts, the author tries to clear logic from ontological commitments, shows how to construct logic of norms and how to use safely different definitions in research works. The book presents a new conception of antinomies and an innovatory approach to realistic epistemology. Moreover, some applications of logical methods are illustrated by examples of semantical analyses of the general notion of similarity and the biological concept of homology. (shrink)

In _Kazimierz Twardowski: A Grammar for Philosophy_ Maria van der Schaar shows the importance of Twardowski’s method, his philosophical grammar, for both the Lvov-Warsaw School, and analytic philosophy today.

This belies, inter alia, the not infrequently repeated statement that LWS was one of the many centers initiated by the Vienna Circle. The achievements of LWS in logic are well recognized, while those relating to philosophy of science are almost unknown. It is in order to fill this gap that some fragments of Zawirski's papers are presented, dealing mainly with causality, determinism, indeterminism and the philosophical implications of relativity and quantum mechanics. His magnum opus 'L'Evolution de la Notion du Temps' (...) is devoted to time. (shrink)

At the age of eight, Karl Popper was puzzling over the idea of infinity and by fifteen was beginning to take a keen interest in his father's well-stocked library of books. Unended Quest recounts these moments and many others in the life of one of the most influential thinkers of the twentieth century, providing an indispensable account of the ideas that influenced him most. As an introduction to Popper's philosophy, Unended Quest also shines. Popper lucidly explains the central ideas in (...) his work, making this book ideal for anyone coming to Popper's life and work for the first time. (shrink)

This book grew out of an international symposium, organized in September 1986 by the Austrian Cultural Institute in Warsaw in cooperation with the Polish Philosophical Society. The topic was: The Vienna Circle and the Lvov-Warsaw School. Since the two phil osophical trends existed in roughly the same time and were close ly related, it was one of the purposes of the symposium to investigate both similarities and thp differences. Some thirty people took part in the symposium, nearly twenty contributions were (...) presented and extensively discussed. The sym posium owed much to the excellent organization and warm hospital ity shown by Dr Georg Jankovic, the Director of the Austrian In stitute. As the person in charge of the scientific programme of the symposium, I take pleasure to acknowledge this debt. It so happened that a month later another symposium of a similar character was held. It took place in the University of Manchester, on the occasion of the centenary of the births of Stanislaw Lesniewski, Tadeusz Kotarbiflski and Wladyslaw Tatarkie wicz. Some papers read at the Manchester symposium form a part of the present volume. It was not possible, for technical reasons (the time factor was one of them), to include in this book all the material from the two symposia. Certain contributions have appeared elsewhere (for instance, K. Szaniawski's 'Ajdukiewicz on Non-Deductive Inference' was published in Danish Yearbook of Philosophy, Vol. 23). On the other hand, certain papers have been written special ly for this volume. (shrink)

The essays can be seen as addressing Tarski's seminal treatment of four basic questions about logical consequence. (1) How are we to understand truth, one of ...

The evening before my talk at this conference on “Tarski and the Vienna Circle”, Professor Hans Sluga of the University of California at Berkeley made the important point that we should discuss not only the historical past but also its impact — in other words, what happened as a result of that past. I agree completely and I am happy to say that I intend to deal with exactly those issues. My title, “How the Unity of Science Saved Alfred Tarski”, (...) has two meanings: the first, quite literal. The second is less so and perhaps stretches the point, but it does bear on the question of “what happened.”. (shrink)
