Book excerpt: First published in 1974, this book is a critical introduction to the work of four quintessential pragmatist philosophers: Charles Sanders Peirce, William James, George Herbert Mead and John Dewey. Alongside providing a general historical and biographical account of the pragmatist movement, the work offers an in depth critical response to the philosophical doctrines of the four main thinkers of the pragmatist movement, with reference to the theories of meaning, knowledge and conduct which have come to define pragmatism.
