A Philosophy Conference in Memory of Imre Ruzsa

September 17-19, 2009
Budapest, Hungary




Imre Ruzsa (1921-2008)



The conference is held in memory of  Imre Ruzsa, the father of modern philosophical logic in Hungary, the founder and the first chair of the Department of Logic at Eötvös University.
 His professional interests centered around modal logic, intensional logic, modeling natural language in systems of intensional logic, and the foundations of logic and mathematics. He always thought of his generalization of A. N. Prior’s concept of semantic value gaps to quantified, intensional and type-theoretic systems as his most important contribution to logic. He was the author of three books in English (
Modal Logic with Descriptions, The Hague, 1982, Intensional Logic Revisited, Budapest, 1991, Introduction to Metalogic, Budapest, 1993), several monographs and textbooks in Hungarian, and many articles in leading logic journals.

Several of
Imre Ruzsa’s former students from across the globe will gather to discuss his legacy, and also to present on some of his favorite themes, topics, and areas—we invite you to do the same.
