Man, sign and cosmos is a vast introduction to the philosophical system created by pragmatism founder, Charles S Peirce. This book carefully analyzes the most important concepts in which, the so-called Aristotle of our time, structured his thinking. Explaining the critique he made to the philosophers that came before him, like Kant and Descartes, Darin McNabb gives account of the adoption and transformation of other traditions and currents. In a progressive and propaedeutic way with Man, sign and cosmos, the reader will be able to comprehend Peirces thinking evolution and the importance of each one of its ramifications and relationships that hold on to each other. This is a meticulous and critical introduction to Peirces architectural philosophy, a study that shows the relevance in his way of explaining the cosmos and human experience in our present day.
