Semiotics is the study of signs ( symbols ) and signification systems.
Scope and main concepts
Semiotics is concerned with how minds produce, communicate, and codify meaning. It applies to any kind of signs or symbols,not just words (as in semantics ), and anything representative—a word, agesture, a sound—is a sign. Even concepts, thoughts, and ideas can be symbols for something else. Semiotics providesinsights and tools for critically examining symbols and information in a variety of fields.
It is human beings' ability to manipulate symbols that allows them to explore the relationships between ideas, things,concepts, and qualities — far beyond the explorations of which any other species on Earth is capable.
Today, four levels can be distinguished:
Rooted in epistemology , the philosophy of science and knowledge, and informal logic, semiotics is increasing in importance with scientific and technological developments. It connects with a variety ofdisciplines:
The philosopher John Locke first coined the term "semeiotike" (from theGreek word σημειον, semeion, meaning "mark" or "sign") in 1690, in An essayconcerning human understanding.
Charles Sanders Peirce ( 1839 - 1914 ), founder of the philosophical school of pragmatism , invented semiotics as a discipline, terming it "semeiotic". This form of semiotics is based onthe notion of signs as triadic relations between an object, its representation, and an interpretant.
Ferdinand de Saussure ( 1857 - 1913 ), the "father" of modern linguistics , invented, at about the same time as Peirce, a subject he called "semiology." Saussure establisheda dyadic notion of signs relating the signifier to the signified.
Umberto Eco made a wider audience aware of semiotics by variouspublications, most notably A Theory of Semiotics. Eco explicitly acknowledges Peirce's importance. One of his novels, The_Name_of_the_Rose , was made into a movie starring Sean Connery and Christian Slater - the book and movie had many significant allusions to semiotics.
Algirdas Greimas developed a structural version of semiotics named generative semiotics. Greimas tried to shift the focus of discipline from signsto systems of signification. Greimas rooted his theory in Saussure, Hjelmslev, LÚvi-Strauss and Merleau-Ponty.
Jay Forrester developed formalisms for complex systems that are usefulfor noting how conflicts in mental models cause problems in group communication. In his paper, " Counterintuitive Behaviorof Social Systems ," for example, he explained miscommunication in human groups.
Biosemiotics is an interdisciplinary science that studies communicationand signification in living systems.
Computational semiotics attempts to engineer theprocess of semiosis in a computationally tractable manner. Computational semioticsmay be understood as artificial intelligence and knowledge representation examined from a semioticperspective.
Literary semiotics applies the theory of signs (and also communication and information theory) to the interpretation of literary works. Literarysemioticians often have an interest in the attempt to apply the tools and techniques of the hard sciences, such as mathematicalformulae and computer analysis of texts, to literarycriticism .
Others, like the French critic, Roland Barthes , and many Marxists , employ semiotic techniques as a tool of political and social criticism and satire . Pop culture artifacts have becomefrequent targets of the semiotic approach, as for example when Barthes deconstructed tag-team wrestling.
Medical semiotics specifically studies the interpretation of patients' description of their symptoms, and has particular importance for theunderstanding of how patients describe pain or other symptoms which a physician cannot experience or measure directly.
