Peirce's Semiotics in the light of His philosophy, Epistemology and His Vision of pragmatism

This paper presents the most important features of Peirce''s semiotics، including the emergence process of signs، their ways of signifying، as well as their practical dimensions. The study of Peirce''s three philosophical categories as well as the issue of «abduction» underlines the central role of Peirce''s semiotics in his ontology and in his epistemology، in such a way that all thoughts and all kinds of process of signification can be considered to be stemming from his conception of signs. According to Peirce، signs are the structure of all thoughts and on this basis، life of every king of knowledge and even the relations between human beings depend on signs. In this regard، a brief comparative study between Peirce''s three categories and the different kinds of perceptions in Islamic philosophy is also mentioned. As a means of analysis of human thoughts and their practical consequences، Peirce''s semiotics has also a pragmatist dimension، even though we can not consider him to be a strict follower of pragmatism. Peirce''s semiotics has been used in various fields including philosophy of media، arts… In this context، one of the practical applications of his semiotics in the interpretation of a work of art is also tackled.
