Artur Rojszczak – författare

"Philosophical Dimensions of Logic and Science" is a collection of contributed papers presented at the 11th International Congress of Logic, Methodology, and Philosophy of Science held in Krakow in 1999. The Congress was a follow-up to the series of meetings, initiated once by Alfred Tarski, which aimed to provide an interdisciplinary forum for scientists, philosophers and logicians. The articles selected for publication in the book comply with that idea and innovatively address current issues in logic, metamathematics, philosophy of language, philosophy of science, and cognitive science, as well as philosophical problems of biology, chemistry and physics. The volume will be of interest to philosophers, logicians and scientists interested in foundational problems of their disciplines.

On the occasion of bis sixtieth birthday, we dedicate this volume to Jan Wo­ leriski-s-our teacher, our colleague, our friend. Both of us are particularly indebted to Jan not only with regards to profes­ sional matters, but some private ones as well. Hence, we hope that he forgives us an occasional lapse into fondness and affection. That said, may the list of bis personalmerits remain shrouded in mystery; rather than unveil them, we open here by appraising Jan's presence from a broader perspective. Tonote that Jan was not always a part of our lives would not evoke surprise. However, to imagine the Institute of Pbilosophy on Grodzka Street or Krakow pbilosophy without him in it would be a harder task-at least for us, Nonethe­ less, we do remember the days when he was commuting to Krakow as a guest lecturer. Is there anything about those days which particularly comes to mind? To shed light on the story which follows, one must begin by stating that the early 1980s when we were studying philosophy was not a bright period. The great masters of Krakow philosophy-Ingarden, Mehlberg, Zawirski, or Dambska-> were either dead or, for political reasons, kept silent. The years following Martial Law (1981-1983) were intellectually very blighted and barren. In the midst of all this we were attending Jan's course on general methodology.

IN MEMORIAM OF ARTUR ROJSZCZAK For a teacher, the opportunity to write the Foreword to a student’s work gives rise to a sense offul?lment and pride. In this case, however, although the latter remains, the former has been effaced.Inawell-ordered world Artur Rojszczak would have perhaps one day written tributes to ourselves. It isapoignant paradox when teachers are called upon to comment posthumously on thework of one of their students. This is a terrible task whichfalls to us—who have been not only mentors and colleagues to Artur, but also simply friends—of eulogizing someone who has died so soon, and so tragically. Artur was killed, together with his father, by an aggressive neighbour on September 27, 2001. Artur’s wife was severely injured in the same attack. Artur was born on March 12, 1968 in S?ubice (close to the Polish-German border). He studied in the Electronics College in Zielona Góra, graduating in 1987. But from very early on his dream was to study philosophy, and to do so at the Jagiellonian University in Cracow; no other place was considered by him seriously. He entered the university in 1988.
