ACTS OF KNOWLEDGE

all the papers present cutting-edge research in their own style, contributing to very lively debates occurring in the literature in logic, philosophical logic and history of logic. But it also hints at Göran s constructivist background, which has been an influence or a challenge for many of the contributors. History, Philosophy and Logic refers directly to Göran s broad interests into the various aspects of the Philosophy of Logic, Mathematics, and Language, their origins and development, especially with the focus on the Modern History of Logic and the philosophical implications thereof. The readers will find scattered all along this volume pieces of -- and reflections on -- all these themes.
