The Difference Between Semiotics and Semiology

What is the relationship between semiotics and semiology? Received wis­dom tells us that the "semiotics" of Charles Sanders Peirce largely overlaps in function and meaning with the "semiology" of Ferdinand de Saussure. Among semioticians more attentive to the nuances of each system, such as Sebeok, Deely, and Eco, semiology occupies that part of semiotics which relates either to conventional communication, or intentional communica­tion, or some other subset of semiotic acts. In this essay I aim to demon­strate quite a different relation between the two fields of study. Drawing upon close readers of Saussure such as Harris and Weber, I will contrast semiotics as an act of "representation" with semiology as an act of "artic­ulation". What I will propose is that semiotics and semiology form wholly separate but contiguous domains of explanation
