How to Make Our Ideas Clear

Charles Sanders Peirce was an American philosopher, logician, mathematician, and scientist who is sometimes known as "the father of pragmatism". He was educated as a chemist and employed as a scientist for 30 years. Today he is appreciated largely for his contributions to logic, mathematics, philosophy, scientific methodology, and semiotics, and for his founding of pragmatism. "How to Make Our Ideas Clear" is the cornerstone for the philosophical school now known as pragmatism, and began the formalization of the scientific method. It is justly regarded as one of the most important philosophical papers ever written.
