Biosemiotics is the synthesis of biology and semiotics, and its main purpose is to show that semiosis is a fundamental component of life, i.e., that signs and meaning exist in all living systems. This idea started circulating in the 1960s and was proposed independently from enquires taking place at both ends of the Scala Naturae. At the molecular end it was expressed by Howard Pattee’s analysis of the genetic code, whereas at the human end it took the form of Thomas Sebeok’s investigation into the biological roots of culture. Other proposals appeared in the years that followed and gave origin to different theoretical frameworks, or different schools, of biosemiotics. They are: (1) the physical biosemiotics of Howard Pattee and its extension in Darwinian biosemiotics by Howard Pattee and by Terrence Deacon, (2) the zoosemiotics proposed by Thomas Sebeok and its extension in sign biosemiotics developed by Thomas Sebeok and by Jesper Hoffmeyer, (3) the code biosemiotics of Marcello Barbieri and (4) the hermeneutic biosemiotics of Anton Markoš. The differences that exist between the schools are a consequence of their different models of semiosis, but that is only the tip of the iceberg. In reality they go much deeper and concern the very nature of the new discipline. Is biosemiotics only a new way of looking at the known facts of biology or does it predict new facts? Does biosemiotics consist of testable hypotheses? Does it add anything to the history of life and to our understanding of evolution? These are the major issues of the young discipline, and the purpose of the present paper is to illustrate them by describing the origin and the historical development of its main schools.

This article proposes to replace current semiotic folk theories by a more complex conception of the role signs play in human societies. It distinguishes between the world and the reality of human beings, describing the perception of the world as a production of images that are projected outward and thereby create reality. While perception takes the world as its object, behavior takes it as a project. A considerable part of the behavior of organisms consists in the production of signs which represent perceptions (as in a photograph), behaviors (as in film), or signs (as in writing, which imitates spoken language). On one hand, signs have the function of making perceptions, behaviors, and signs in themselves communicable; on the other, they serve to anticipate perceptions, behaviors, and signs which are not yet real. This second type of signs (schemata) takes reality as a project in exactly the same way in which ordinary behavior takes the world as its project. The article ends with a discussion of the various types of schematic signs used by human beings to control their perceptual, behavioral, and sign spaces, and suggests a systematic improvement of our semiotic folk theories in order to facilitate orientation in the reality created by ourselves.

This paper discusses how the second order cybernetics of von Foerster, Maturana, Varela and Luhmann, can be fruitfully integrated with Peirce’s semiotics through the bio-semiotics of Hoffmeyer. The conclusion is that what distinguish animals from machines is that they are autopoietic, have code-duality and through their living organization constitutes a biological interpretant. Through this they come to inhabit a new life world: their games of life take place in their own semiotic Umwelt (von Uexküll). It is the biological context and the history of the species and the individual the determine the meaning of signs in the structural couplings that constitutes the channels of communication. Inspired by Wittgenstein’s theory of language games as the context that determines semantic content of the expressions of sentences, we suggest that animals participate in sign games.

This paper summarizes recent attempts by this author to create a transdisciplinary, non-Cartesian and non-reductionistic framework for information studies in natural, social, and technological systems. To confront, in a scientific way, the problems of modern information technology where phenomenological man is dealing with socially constructed texts in algorithmically based digital bit-machines we need a theoretical framework spanning from physics over biology and technological design to phenomenological and social production of signification and meaning. I am working with such pragmatic theories as second order cybernetics (coupled with autopolesis theory), Lakoffs biologically oriented cognitive semantics, Peirce’s triadic semiotics, and Wittgenstein’s pragmatic language game theory. A coherent synthesis of these theories is what the cybersemiotic framework attempts to accomplish.

In the context of the question of the emergence of mind in evolution the present paper argues that the concept of linguistic motivation, through the theory of embodiment in cognitive semantics, can be connected with the concept of motivation in ethology. This connection is established through Lakoff and Johnson’s embodied cognitive semantics on the one hand and on the other hand through the theory of biosemiotics. The biosemiotics used is based on C. S. Peirce´s semiotics and the work of J. von Uexkull. Motivation will in this context be understood as a decisive factor in determining which kind of interpretant a living system constructs when perturbed by a significant disturbance in its signification sphere. From this basis the concept of sign stimuli in Ethology, based on the concept of innate release response mechanism (IRM,) is paralleled with the concept of embodied metaphorical categorization based on the concept of idealized cognitive models (ICM). It is realized that we are dealing with motivation on two different levels, that of the linguistic and that of the perceptual-behavioral level. The connection is made through pragmatic language and sign theory viewing language as getting its meaning through language games integrated in cultural life forms and animals signs to get their meaning through sign games and natural life forms. Further connection is made through the common insight of the significant role of embodiment to create signification through the construction of a signification sphere. The later concept is a Peircian biosemiotic conceptualization of von Uexkull’s orginal Umwelt concept.

This paper discusses various suggestions for a philosophical framework for a trans-disciplinary information science or a semiotic doctrine. These are: the mechanical materialistic, the pan-informational, the Luhmanian second order cybernetic approach, Peircian biosemiotics and finally the pan-semiotic approach. The limitations of each are analysed. The conclusion is that we will not have to choose between either a cybernetic-informational or a semiotic approach. A combination of a Peircian-based biosemiotics with autopoiesis theory, second order cybernetics and information science is suggested in a five-levelled cybersemiotic framework. The five levels are 1) a level of Firstness, 2) a level of mechanical matter, energy and force as Secondness, 3) a cybernetic and thermodynamic level of information, 4) a level of sign games and 5) a level of conscious language games. These levels are then used to differentiate levels of information systems, sign and language games in human communication. In our model Maturana and Varela’s description of the logic of the living as autopoietic is accepted and expanded with Luhmann’s generalization of the concept of autopoiesis, to cover also to psychological and socio-communicative systems. Adding a Peircian concept of semiosis to Luhmann’s theory in the framework of biosemiotics enables us to view the interplay of mind and body as a sign play. I have in a previous publication (see list of references) suggested the term “sign play” pertaining to exosemiotics processes between animals in the same species by stretching Wittgenstein’s language concept into the animal world of signs. The new concept of intrasemiotics designates the semiosis of the interpenetration between biological and psychological autopoietic systems as Luhmann defines them in his theory. One could therefore view intrasemiotics as the interplay between Lorenz’ biological defined motivations and Freud’s Id, understood as the psychological aspect of many of the natural drives. In the last years of the development of his theory, Lorenz worked with the idea of how emotional feedback introduced just a little learning through pleasurable feelings into instinctive systems because, as he reasoned, there must be some kind of reward of going through instinctive movements, thus making possible the appetitive searching behaviour for sign stimuli. But he never found an acceptable way of modelling motivation in biological science. I am suggesting a cybersemiotic model to combine these approaches, defining various concepts like thought-semiotics, phenosemiotic and intrasemiotics, combining them with the already known concepts of exosemiotics, ecosemiotics, and endosemiotics into a new view of self-organizing semiotic processes in living systems. Thus a new semiotic level of description is generated, where mind-body interactions can be understood on the same description level.

In this paper, a semiotic framework for natural and artificial adaptive percept-action systems is presented. The functional organizations and operational structures of percept-action systems with different degrees of adaptivity and self-construction are considered in terms of syntactic, semantic, and pragmatic relations. Operational systems-theoretic criteria for distinguishing semiotic, sign-systems from nonsemiotic physical systems are proposed. A system is semiotic if a set of functional sign-states can be identified, such that the system’s behavior can be effectively described in terms of operations on sign-types. Semiotic relations involved in the operational structure of the observer are outlined and illustrated using the Hertzian commutation diagram. Percept-action systems are observers endowed with effectors that permit them to act on their surrounds. Percept-action systems consist of sensors, effectors, and a coordinative part that determines which actions will be taken. Cybernetic systems adaptively steer behavior by altering percept-action mappings contingent on evaluated performance measures via embedded goals. Self-constructing cybernetic systems use signs to direct the physical construction of all parts of the system to create new syntactic, semantic, and pragmatic relations. When a system gains the ability to construct its material hardware and choose its semiotic relations, it achieves a degree of epistemic autonomy, semantic closure, and pragmatic self-direction.

This chapter outlines a broad theory of sign use in natural and artificial systems that was developed over several decades within the context of theoretical biology, cybernetics, systems theory, biosemiotics, and neuroscience. Different conceptions of semiosis and information in nature are considered. General functional properties of and operations on signs, including measurement, computation, and sign-directed actions are described. A taxonomy of semiotic systems is built up from combinations of these operations. The respective functional organizations and informational capabilities of formal systems and computempiral-predictive scientific models, percept-action systems, purposive goal-seeking systems, and self-constructing systems are discussed. Semiotic relations are considered in terms of Morrisean semiotic triad of syntactics, semantics, and pragmatics. Analysis of statetransition structure is used to demarcate functional boundaries, such as epistemic and control cuts. Capabilities for open-ended behavior, combinatoric and emergent creativity, and umwelt expansion are taken up. Finally, basic problems of neurosemiotics, neural coding, and neurophenomenology are outlined.

This article deals with the problem of how operationally closed systems can construct a reality and therefore get their bearings in the world. But rather than looking for new theoretical solutions, it suggests going back to the empirical philosophical tradition of early modernity, in order to find a solution. Following a suggestion by the leaders of both first- and second-order cybernetics, Wiener and Foerster, this article reframes Hume’s theory of causal inference in order to make the case not only that Hume anticipated second-order cybernetics in interesting ways, but also that modern cognitive sciences can use Hume and second-order cybernetics to inform each other leading to a better understanding of both. Starting from the statement according to which the problem of causality represents ‘one of the most sublime questions in philosophy, ’ the article goes deeply inside the problem of causality in order to argue that the modern approach to epistemology has to be conceived of as a process of internalization of cognitive facts. This search path leads to casting a new light on the paramount concept of sign, conceived of as the possibility that certain environmental events or data again set off the self-reference of a cognitive system, which thus switches from memory to expectation. The aim of this article is finally to show that the main results of an interdisciplinary theory of cognition such as second-order cybernetics are particularly congruent with the speculations of the Scottish philosopher, and that Hume’s reflections maintain an extraordinary relevance regarding the most advanced elaboration of the main epistemological problems
