The history of interwar Polish logic, including philosophical logic, is still a relatively little known area, especially if compared with the movement's well-documented contemporaries - the Vienna Circle or the Berlin Circle, for instance. The book aims to address this lacuna, by presenting the state of the art of research into this part of the history of analytic philosophy. It comprises thirteen essays, written by outstanding philosophers and exemplifying different approaches to the history of philosophy. One approach focuses on some little known aspects of Polish philosophy (e.g., Lesniewski's arithmetic, Tarski's geometry, philosophy of mathematics in interwar Krakow), analyzing it in great detail, sometimes by using current formal techniques. Another group of papers looks at the inspiration the Poles got from the founding fathers of analytic philosophy (Frege, Husserl, Wittgenstein), and locates Polish philosophy in the larger landscape of European analytic philosophy. Finally, some contributors pick a topic from the Polish school (sometimes only mentioned, but not developed by the Poles), and construct an alternative account which is then compared with the earlier account. Most of the papers were presented at a symposium celebrating the 70th birthday of Jan Wolenski, whose book "Logic and Philosophy of the Lvov-Warsaw School" has played a substantial role in sparking contemporary interest in Polish analytic philosophy.

This is the second of two volumes containing papers submitted by the invited speakers to the 11th international Congress of Logic, Methodology and Philosophy of Science, held in Cracow in 1999, under the auspices of the International Union of History and Philosophy of Science, Division of Logic, Methodology and Philosophy of Science. The invited speakers are the leading researchers and accordingly the book presents the current state of the intellectual discourse in the respective fields.

The papers delivered at the congress were divided into 17 sections. Thus the structure of the volume corresponds to the very schedule of the congress. Volume one contains the opening lecture by Andrzej K. WrA3blewski as well as invited papers in sections of Proof Theory, Model Theory, Recursion Theory, Axiomatic Set Theory, Logic and Computation, Logic, Language and Cognition, Methodology, Probability, Induction, and Decision Theory, Philosophy of Logic, Mathematics, and Computer Science, and Philosophy of the Physical Sciences.

This volume contains papers on truth, logic, semantics, and history of logic and philosophy. These papers are dedicated to Jan Wolenski to honor his 60th birthday. Jan Wolenski is professor of philosophy at the Department of Philosophy of the Jagiellonian University in Cracow, Poland. He is likely to be the most well-known Polish philosopher of this time, best known for his work on the history of the philosophy and logic of the Lvov-Warsaw School.

This volume consists of papers delivered at the conference 'The Lvov-Warsaw School and Contemporary Philosophy', organised in celebration of the hun- dredth anniversary ofKazimierz Twardowski's first lecture as Professor of Phi- losophy at Lvov University. This lecture can be regarded as the starting point of the development of analytic philosophy in Poland, which culminated in the Warsaw School of Logic. The conference was held in Lvov (15-17 November) and Warsaw (19-21 November 1995). It was organised jointly by the Ukrainian Academy of Sci- ences and the Polish Academy of Sciences. The general organisation was un- dertaken by Professor Andrzej Grzegorczyk (polish Academy of Sciences) and Professor Marat Vernikov (Ukrainian Academy of Sciences). Professors Jaroslaw Isaievich (Ukrainian Academy of Sciences) and Jan Wolenski (Jagiel- Ionian University) were responsible for the scientific programme. Over 100 philosophers participated in the conference. Papers published in this volume are organised according to the sections of the conference and rep- of the papers delivered. resent a selection The editors would like to express their gratitude to Professor Andrzej Grze- gorczyk, spiritus movens of the conference, who, by including the present vol- ume in a programme of publications connected with the hundredth anniversary of the Lvov-Warsaw School, provided financial support for its preparation.

The book presents the state of the art of research into the legacy of interwar Polish analytic philosophy and exemplifies different approaches to the history of philosophy. It contains discussions and reconstructions of aspects of Polish philosophy and logic as well as reactions to and developments of this tradition.

The papers delivered at the congress were divided into 17 sections. Thus the structure of the volume corresponds to the very schedule of the congress. Volume two contains the closing lecture by John Maynard Smith and the invited papers in sections of Philosophy of the Biological Sciences, Philosophy of Cognitive Science and Artificial Intelligence, Philosophy of Linguistics, Philosophy of the Social Sciences, Ethics of Science and Technology, History of Logic, Methodology, and Philosophy of Science, Philosophical Questions Raised by the History and Sociology of Science. It also contains invited papers in two special symposia: A Hundred Years of the Philosophy of Science and Cognitive Science Meets Philosophy of Science, as well as a special lecture delivered by Stanislaw Lem.
We hope that the book could be of interest to philosophers, biologists, linguists, cognitive scientists, social scientists, sociologists, as well as historians and philosophers of science.
