Peirce’s Pragmatism: A Radical Perspective situates Charles Sanders Peirce’s thought within his semiotic theory and its potential for application in cultural studies and the critique of ideologies. E. San Juan Jr. contextualizes pragmaticism historically and examines Peirce’s discourses on semiotics, ethics, and aesthetics and suggests their analogies with the radical critiques of Marx and other progressive trends. This book may be read as a provocation and a challenge for everyone to heed Peirce’s own maxim to inquire seriously into the effect of ideas on transforming the conduct of life by changing habits, traditional beliefs, purposes.
