This open access book is the first ever collection of Karl Popper's writings on deductive logic. Karl R. Popper (1902-1994) was one of the most influential philosophers of the 20th century. His philosophy of science ("falsificationism") and his social and political philosophy ("open society") have been widely discussed way beyond academic philosophy. What is not so well known is that Popper also produced a considerable work on the foundations of deductive logic, most of it published at the end of the 1940s as articles at scattered places. This little-known work deserves to be known better, as it is highly significant for modern proof-theoretic semantics. This collection assembles Popper's published writings on deductive logic in a single volume, together with all reviews of these papers. It also contains a large amount of unpublished material from the Popper Archives, including Popper's correspondence related to deductive logic and manuscripts that were (almost) finished, but did not reach the publication stage. All of these items are critically edited with additional comments by the editors. A general introduction puts Popper's work into the context of current discussions on the foundations of logic. This book should be of interest to logicians, philosophers, and anybody concerned with Popper's work.

This is a study of the growth of the right wing in a reunited Germany. Since the end of the Cold War, an explosion of xenophobia and attacks on foreigners - some of them asylum-seekers - has attracted world-wide media attention. Coming after the seemingly miraculous celebration of freedom accompanying the fall of the Berlin Wall and the country's reunification, these events have caused acute anxiety within Germany itself. These phenomena are not exclusive to Germany, but their undertones of Nazism have prompted the question: how could this happen in a country that had so firmly repudiated its past and rightly prided itself on its anti-fascism and liberal democracy? The author sets this development in its historical context, showing the long-established continuity of right-wing influence and power in German conservative politics, and he explores the effects of the end of the Cold War on German society and politics. He also examines the growth of xenophobia and right-wing attitudes in the former GDR since the implosion of communism. Germany's current position as a regional super-power and its contribution to European economic progress, make this text a significant and topical contribution.
