work is Prolegomena to a Theory of Language, which was expanded in Résumé of the Theory of Language, a formal development of glossematics, his scientific calculus of language. Charles W. Morris (1901–1979): Unlike his mentor George Herbert Mead, Morris was a behaviorist and sympathetic to the Vienna Circle positivism of his colleague, Rudolf Carnap. Morris was accused by John Dewey of misreading Peirce. In his 1938 Foundations of the Theory of Signs, he defined semiotics as grouped into three branches: Syntactics/syntax: deals with the formal properties and interrelation of signs and symbols, without regard to meaning. Semantics: deals with the formal structures of signs, particularly the relation between signs and the objects to which they apply (i.e. signs to their designata, and the objects that they may or do denote). Pragmatics: deals with the biotic aspects of semiosis, including all the psychological, biological, and sociological phenomena that occur in the functioning of signs. Pragmatics is concerned with the relation between the sign system and sign-using agents or interpreters (i.e., the human or animal users). Thure von Uexküll (1908–2004), the "father" of modern psychosomatic medicine, developed a diagnostic method based on semiotic and biosemiotic analyses. Roland Barthes (1915–1980) was a French literary theorist and semiotician. He often would critique pieces of cultural material to expose how bourgeois society used them to impose its values upon others. For instance, the portrayal of wine drinking in French society as a robust and healthy habit would be a bourgeois ideal perception contradicted by certain realities (i.e. that wine can be unhealthy and inebriating). He found semiotics useful in conducting these critiques. Barthes explained that these bourgeois cultural myths were second-order signs, or connotations. A picture of a full, dark bottle is a sign, a signifier relating to a signified: a fermented, alcoholic beverage—wine. However, the bourgeois take this signified and apply their own emphasis to it, making "wine" a new signifier, this time relating to a new signified: the idea of healthy, robust, relaxing wine. Motivations for such manipulations vary from a desire to sell products to a simple desire to maintain the status quo. These insights brought Barthes very much in line with similar Marxist theory. Algirdas Julien Greimas (1917–1992) developed a structural version of semiotics named, "generative semiotics", trying to shift the focus of discipline from signs to systems of signification. His theories develop the ideas of Saussure, Hjelmslev, Claude Lévi-Strauss, and
