Charles Sanders Peirce was an American scientist, philosopher, and logician, best known for his contribution to the logic of relations and to pragmatism as a research method. He began his career by assisting his father in the ‘Geodetic Survey’ and contributed to the research on pendulum swinging to measure gravitational force. A ‘Harvard’ graduate, he redefined the fields of logic, mathematics, and philosophy. He believed in the three methods of solving a problem: abduction, induction, and deduction. He was devoted to the mathematical fields of linear algebra, probability, and statistics. He also linked his work to semiotics, or the theory of signs. He rediscovered Kantian philosophy and laid down the concepts of “pragmatism” and later coined the word “pramaticism.” Though his works have remained hugely unparalleled, he died a recluse, plagued with poverty and illness. A lot of his previously unpublished works were released posthumously.
