Sza- niawski was also a member of the Polish Home Army (AK), one of the young- est. He was arrested and spent the last period of the war as a prisoner in Auschwitz. After 1945, he continued his studies in the University of L6dz; his Master thesis was devoted to French moral thought of the 17th and 18th cen- turies. Then he worked in the Department of Ethics in L6dZ. In 1950, he received his Ph. D. on the basis of the dissertation on the concept of honour in knight groups in the Middle Ages; Maria Ossowska was the supervisor. In the early fifties he moved to Warsaw to the Department of Logic, directed by Kotarbinski. He took his habilitation exams in 1961. In 1969 he became a professor. Since 1970 he was the head of Department of the Logic at the Warsaw University. In the sixties Szaniawski was also the Dean of the Faculty of Philosophy and Sociology.In 1984 he was elected the Rector Magnificus of the Warsaw University but the Ministry overruled the autonomous democra- tic vote of the academic community. He served as the President of the Polish (since 1977) taking this post after Kotarbinski.

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.
