This paper sketches a network of analogies reaching from linguosemiotics (including theory of reference in analytical philosophy of language) to biosemiotics. It results in the following proportion: attributive use of referring expressions : referential use of referring expressions : ‘generative’ use of referring expressions = signifying : referring : ‘poetic pointing’ = ‘functional’ semiosis : ‘adaptational’ semiosis : semiosis in the narrow sense.

Pragmatics, i.e., a system of values (or goals) in agent behavior, marks the boundary between physics and semiotics. Agents are defined as systems that are able to control their behavior in order to increase their values. The freedom of actions in agents is based on the distinction between macrocharacters that describe the state or stage, and micro-characters that are interpreted as memory. Signs are arbitrarily established relations between micro- and macro-characters that are anticipated to be useful for agents. Three kinds (...) of elementary signs (action, perception, and association) have been developed in agents via evolution and learning to support useful and flexible behaviors. The behavior of agents can be explained, predicted, and modified using the optimality principle, according to which agents select those actions that are expected to increase their value. However, agents may select actions based on their own model of the world, which have to be reconstructed in order to predict their behavior. Pragmatics in agents can be induced, learned from individual experience or natural selection, or adopted. (shrink)

Synthesizing important research traditions in information theory, structuralist semiotics, and generative linguistics, at least three main types of semiotic indeterminacy must be distinguished: Kolmogorov’s notion of randomness defined as sequential incompressibility, de Saussure’s principle of contingency of sign which ensures the possibility of translation between different sign systems, and Chomsky’s idea of indefiniteness in generative mechanisms as a requirement for the explanation of semiotic creativity. These types of semiotic indeterminacy form an abstract system useful for the description of concrete sign (...) processes in their syntactic, semantic, and pragmatic dimension. In his philosophical reflections on modern biology, Jacques Monod used the conceptual opposition chance versus necessity to analyse several phenomena of indeterminacy (especially in molecular biology). The biosemiotic approach to life permits to apply the suggestedsystem of semiotic indeterminacy on these phenomena. (shrink)
