The Berlin Group for scientific philosophy was active between 1928 and 1933 and was closely related to the Vienna Circle. In 1930, the leaders of the two Groups, Hans Reichenbach and Rudolf Carnap, launched the journal Erkenntnis. However, between the Berlin Group and the Vienna Circle, there was not only close relatedness but also significant difference. Above all, while the Berlin Group explored philosophical problems of the actual practice of science, the Vienna Circle, closely following Wittgenstein, was more interested in problems of the language of science. The book includes first discussion ever (in three chapters) on Walter Dubislav's logic and philosophy. Two chapters are devoted to another author scarcely explored in English, Kurt Grelling, and another one to Paul Oppenheim who became an important figure in the philosophy of science in the USA in the 1940s-1960s. Finally, the book discusses the precursor of the Nord-German tradition of scientific philosophy, Jacob Friedrich Fries.

This biography attempts to shed light on all facets of Zermelo's life and achievements. Personal and scientific aspects are kept separate as far as coherence allows, in order to enable the reader to follow the one or the other of these threads. The presentation of his work explores motivations, aims, acceptance, and influence. Selected proofs and information gleaned from unpublished notes and letters add to the analysis.

This volume takes a reflective position with respect to the conference series "Foundations of the Formal Sciences" (FotFS) and asks: * What are the Formal Sciences? * Can we develop a theoretical classification of the sciences that juxtaposes the formal sciences to the natural sciences, social sciences, and humanities? Can we do this solely by identifying common methodological features? * Can we identify changes of the notion of formal sciences over time? How were the areas that we now conceived as the "Foundations of the Formal Sciences" classified throughout history? Investigating the "History of the Concept of the Formal Sciences" to find answers to an array of questions with this wide scope, you need an enthusiastic group of researchers interested in going beyond the traditional boundaries of their subjects covering at once the philosophical, historical and logical issues at hand, like the authors of this volume. The papers in this volume stand witness to our success in touching the mentioned questions. It will be of interest to philosophers, sociologists, historians, and logicians, and covers many aspects of the history of the formal sciences from the Bronze Age to the early XXIst century.
