"Participation in the Munstersche Vorlesungen zur Philosophie 2005 was an honor and a genuine intellectual pleasure for me. The symposium, with all its contributions by the Munster faculty and students, was a wonderfully valuable experience. I can hardly do justice to its spirit of free discussion, or adequately express my thanks, by these short replies. But I think that they will testify clearly to the stimulation the symposium provided and to how much I learned from this exchange." Bas van Fraassen
