History of Formal Logic (Classic Reprint)

This history of the problems of formal logic, which we believe to be the first comprehensive one, has grown only in small part from the authors own researches. I ts writing has been made possible by a small group of logicians and historians of logic, those above all of the schools of Warsaw and Munster. It is the result of their labours that the work chiefly presents, and the author offers them his thanks, especially to the founders Jan Lukasiewicz and Heinrich Scholz. A whole series of scholars has been exceptionally obliging in giving help with the compilation. Professors E. W. Beth (A msterdam), Ph. Boehner O.F.M. (S t. Bonaventure, N.Y.), A. Church (P rinceton), 0. Gigon (B ern), D. Ingalls (H arvard), J. Lukasiewicz (D ublin), B. Mates (B erkeley, California), E. Moody (C olumbia University, New York), M. Morard O.P. (F ribourg), C. Regamey (F ribourgL ausanne) and I. Thomas O.P. (B lackfriars, Oxford) have been kind enough to read various parts of the manuscript and communicate to me many valuable remarks, corrections and additions. Thanks to them I have been able to remove various inexactitudes and significantly improve the content. Of course they bear no responsibility for the text in its final state. The author is further indebted for important references and information toM ile. M. T. dA lverny, Reader of theD epartment of Manuscripts of theB ibliotheque Nationale in Paris, Dr. J. Yajda of the Centre National de la Recherche Scientifique in Paris, Professors L. Minio-P aluello (O xford), S. Hulsewe (L eiden), H. Hermes and H. Scholz (M unster i. W.), R. Feys (L ouvain) and A. Badawi (F uad University, Cairo). Dr. A. Menne has been kind enough to read the proofs and make a number of suggestions. My assistant, Dr. Thomas Raber, has proved a real collaborator throughout. In particular, I could probably not have achieved the translation of the texts in
