Semiotics
Semiotics is the study of sign processes , or signification and communication, signs and symbols, both individually and grouped into sign systems. It includes the study of how meaning is constructed and understood.
Communication is defined as the process of transferring data from a source to a receiver as efficiently and effectively as possible. Although, communication theorists construct models based on codes, media, and contexts to explain the biology, psychology, and mechanics involved. Both disciplines also recognise that the technical process cannot be separated from the fact that the receiver must decode the data, i.e., be able to distinguish the data as salient and make meaning out of it. This implies that there is a necessary overlap between semiotics and communication.
Perhaps more difficult is the distinction between semiotics and the philosophy of language. In a sense, the difference is a difference of traditions more than a difference of subjects. Different authors have called themselves “philosopher of language” or “semiotician”. This difference does not match the separation between analytic and continental philosophy. On a closer look, there may be found some differences regarding subjects. Philosophy of language pays more attention to natural languages or to languages in general, while semiotics is deeply concerned about non-linguistic signification.
Roland Barthes is a key figure in international intellectual life. He is one of the most important intellectual figures to have emerged in postwar France and his writings continue to have an influence on critical debates today.
Barthes is particularly interested, not so much in what things mean, but in how things mean. One of the reasons Barthes is a famous and well-known intellectual figure is his skill in finding, manipulating and exploiting theories and concepts of how things come to mean well before anyone else. As an intellectual, Barthes is associated with a number of intellectual trends (e.g. structuralism and post-structuralism) in postwar intellectual life. However, at the time of Mythologies, Barthes main interest was in semiology, the `science of signs’.
