This is a study edition of Charles Sanders Peirce's manuscripts for lectures on pragmatism given in spring 1903 at Harvard University. Excerpts from these writings have been published elsewhere but in abbreviated form. Turrisi has edited the manuscripts for publication and has written a series of notes that illuminate the historical, scientific, and philosophical contexts of Peirce's references in the lectures. She has also written a Preface that describes the manner in which the lectures came to be given, including an account of Peirce's life and career pertinent to understanding the philosopher himself. Turrisi's introduction interprets Peirce's brand of pragmatism within his system of logic and philosophy of science as well as within general philosophical principles.

Charles S. Peirce's "Illustrations of the Logic of Science" is an early work in the philosophy of science and the official birthplace of pragmatism. It contains Peirce's two most influential papers: "The Fixation of Belief" and "How to Make Our Ideas Clear," as well as discussions on the theory of probability, the ground of induction, the relation between science and religion, and the logic of abduction. Unsatisfied with the result and driven by a constant, almost feverish urge to improve his work, Peirce spent considerable time and effort revising these papers. These efforts gained significant momentum after the turn of the century when Peirce sought to establish his role in the development of pragmatism while distancing himself from the more popular versions that had become current. The present edition brings together the original series as it appeared in "Popular Science Monthly" and a selection of Peirce's later revisions, many of which remained hidden in the mass of messy manuscripts that were left behind after his death in 1914.

"One of the most original thinkers and system builders of any time, and certainly the greatest philosopher the United States has ever seen."-Joseph Brent, author of Charles Sanders Peirce: A Life. "Peirce's achievements would take a short book to describe adequately. In philosophy, he founded the most distinctively American school of thought-Pragmatism. As the founder of pragmatism, he was the intellectual hero of both John Dewey and William James. He also created single-handedly the large discipline called Semeiotic-the study of the working of signs-a discipline which engages scholars all over the world. He was perhaps the first modern Historian of Science, and he was certainly one of the great founders of Mathematical Logic. He was, in truth, one of the rare thinkers who deserves the overworked title of 'genius.'"-Hilary Putnam, author of Pragmatism: An Open Question. "Most people never heard of him, but they will."-Walker Percy. Chance, Love, and Logic contains two books by Charles Sanders Peirce (1839-1914) which are among his most important and widely influential. The first is Illustrations of the Logic of Science. The opening chapters, "The Fixation of Belief" and "How to Make Our Ideas Clear," mark the beginning of pragmatism. The second presents Peirce's innovative and influential essays on scientific metaphysics. Morris Raphael Cohen is the author of Law and the Social Order and Reason and Nature. Kenneth Laine Ketner is Charles Sanders Peirce Professor of Philosophy at Texas Tech University and the author of His Glassy Essence.
