With the present volume, the presentation of Peirce’s philosophical thought reaches its metaphysical culmination. It embodies the effort of the founder of Pragmatism to develop a metaphysics which will conform to the canons of scientific method, and at the same time provide for real novelty, objective universal laws of nature, cosmical and biological evolution, feeling, and mind. To his previously published papers on chance, continuity, God, and other metaphysical themes, the editors have added a considerable number of unpublished manuscripts which clarify and develop the implications of Peirce’s fundamental world-view. The volume contains those speculative views of Peirce which so deeply influenced his contemporaries, including his discussions of tychism and synechism and of the religious aspects of metaphysics.

This volume contains the published contributions of one of the founders of modern logic and America’s greatest logical genius. It is not only of historical but of contemporary interest because of its many acute discussions of fundamental logical problems. To assist the general reader, the editors have prefixed to the text a selected list of important topics and have provided many footnotes and an exhaustive index.

The present, the longest volume of the series of Peirce’s Collected Papers, reveals most clearly his stature as a logician and a student of the foundations of mathematics. It includes not only some striking anticipations of recent work in logic and the foundations of mathematics but also a number of vital contributions to these subjects as now understood. In addition there is an entirely original treatment of logical diagrams which makes possible a detailed analysis of the process of reasoning and provides the link between modern logic and Peirce’s conception of pragmatism. It is the most advanced and important of the volumes on exact logic.

Charles Sanders Peirce has been characterized as the greatest American philosophic genius. He is the creator of pragmatism and one of the founders of modern logic. James, Royce, Schroder, and Dewey have acknowledged their great indebtedness to him. A laboratory scientist, he made notable contributions to geodesy, astronomy, psychology, induction, probability, and scientific method. He introduced into modern philosophy the doctrine of scholastic realism, developed the concepts of chance, continuity, and objective law, and showed the philosophical significance of the theory of signs and mathematical logic. The present series is the first published edition of his systematic works.
