An original and ingenious introduction to the basic, experimental, trial-and-error process by which we acquire and validate facts and beliefs and through which we gain understanding and truth. Elements of Knowledge is an engaging introductory text, effectively and imaginatively designed to bring a working understanding and appreciation of the fundamental tenets and methods of the American school of philosophy known as pragmatism, as articulated by its founder C. S. Peirce, to undergraduates and general readers. It presents and explains the basic pragmatic tools that are the common thread in our acquisition and development of knowledge, whether in an academic, vocational, or professional setting, or in life at large. Pragmatism guides, without dictating, examinations of ordinary human experience, creative learning in all fields, and progress in academic disciplines. This book is intended for use by both general readers and students, particularly those in introductory logic or related philosophy courses. It will also fit well in the design of many core curriculum or general education course requirements. It is ultimately meant to be accessible and beneficial to anyone seeking a clearer understanding of the unifying principles for acquiring and assessing the soundness of all knowledge.
