In philosophy, Charles Sanders Peirce founded the most distinctively American school of thought - Pragmatism. 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. This book contains two of his books.

Two of the most important and influential works by Charles Sanders Peirce (1839-1914) here in one volume. The first marks the beginning of pragmatism. The second presents Peirce's innovative essays on scientific metaphysics. (Peirce was) "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, biographer.
