In recent years, Charles Sanders Peirce has emerged, in the eyes of philosophers both in America and abroad, as one of America’s major philosophical thinkers. His work has forced us back to philosophical reflection about those basic issues that inevitably confront us as human beings, especially in an age of science. Peirce’s concern for experience, for what is actually encountered, means that his philosophy, even in its most technical aspects, forms a reflective commentary on actual life and on the world in which it is lived. In Charles S. Peirce: On Norms and Ideals, Potter argues that Peirce’s doctrine of the normative sciences is essential to his pragmatism. No part of Peirce’s philosophy is bolder than his attempt to establish esthetics, ethics, and logic as the three normative sciences and to argue for the priority of esthetics among the trio. Logic, Potter cites, is normative because it governs thought and aims at truth; ethics is normative because it analyzes the ends to which thought should be directed; esthetics is normative and fundamental because it considers what it means to be an end of something good in itself. This study shows that pierce took seriously the trinity of normative sciences and demonstrates that these categories apply both to the conduct of man and to the workings of the cosmos. Professor Potter combines sympathetic and informed exposition with straightforward criticism and he deals in a sensible manner with the gaps and inconsistencies in Peirce’s thought. His study shows that Peirce was above all a cosmological and ontological thinker, one who combined science both as a method and as result with a conception of reasonable actions to form a comprehensive theory of reality. Peirce’s pragmatism, although it has to do with "action and the achievement of results, is not a glorification of action but rather a theory of the dynamic nature of things in which the "ideal" dimension of reality – laws, nature of things, tendencies, and ends – has genuine power for directing the cosmic order, including man, toward reasonable goals.

This book is an attempt to understand a significant part of the complex thought of Charles Sanders Peirce, especially in those areas which interested him most: scientific method and related philosophical questions. It is organized primarily from Peirce's own writings, taking chronological settings into account where appropriate, and pointing out the close connections of several major themes in Peirce's work which show the rich diversity of his thought and its systematic unity. Following an introductory sketch of Peirce the thinking and writer is a study of the spirit and phases of scientific inquiry, and a consideration of its relevance to certain outstanding philosophical views which Peirce held. This double approach is necessary because his views on scientific method are interlaces with a profound and elaborate philosophy of the cosmos. Peirce's thought is unusually close-knit, and his difficulty as a writer lies in his inability to achieve a partial focus without bringing into view numerous connections and relations with the whole picture of reality. Peirce received some of the esteem he deserves when the publication of his Collected Papers began more than thirty-five years ago. Some reviewers and critics, however, have attempted to fit Peirce into their own molds in justification of a particular position; others have disinterestedly sought to present him in completely detached fashion. Here, the author has attempted to understand Peirce as Peirce intended himself to be understood, and has presented what he believes Perice's philosophy of scientific method to be. He singles out for praise Peirce's Greek insistence on the primacy of theoretical knowledge and his almost Teilhardian synthesis of evolutionary themes. Primarily philosophical, this volume analyzes Peirce's thought using a theory of knowledge and metaphysics rather than formal logic.
