Tommi Vehkavaara Why and how to naturalize semiotic concepts for biosemiotics
abstract | view |  rights & permissions
Any attempt to develop biosemiotics either towards a new biological ground theory or towards a metaphysics of living nature necessitates some kind of naturalization of its semiotic concepts. Instead of standard physicalistic naturalism, a certain kind of semiotic naturalism is pursued here. The naturalized concepts are defined as referring only to the objects of our external experience. When the semiotic concepts are applied to natural phenomena in biosemiotics, there is a risk of falling into anthropomorphic errors if the semiotic concepts remain mentalistic. It is suggested that there really is an anthropomorphic error or “hidden prototype fallacy” arising from Peirce’s prototype for semiosis: the research process of an experimental scientist. The fallacy lies in the concept of the object of representation — it is questionable whether there are any objects of representation for bacteria and whether the DNA-signs have any objects. The conclusion is that Peircean semiotic concepts are naturalizable but only if they are based on some more primitive concept of representation. The causal origins of representations are not relevant, only their anticipative consequences (i.e. meaning).

Vefa Karatary, Yağmur Denizhan Evolution of the “window”
abstract | view |  rights & permissions
We propose a general model that integrates meta-system transition theory with biosemiotics on the basis of an “evolvable window” metaphor. The evolution of the “window” proceeds via meta-system transitions, during which new windows are created iteratively on the “inner” side of the preexisting ones, generating a “telescope” growing inwards starting from the “outside”. The tendency of “inwards growth” of the “telescope” can be explained in terms of the following circular causality: (1) the tendency leading from unity towards individualisation, (2) individual learning providing a basis for more complex semiotic interactions, (3) creation of additional, nonconflicting “values” leading to habit formation, (4) strong control bringing forth a unification at a higher (meta-system) level. Using the proposed metaphor we hope to provide clarity to the fluctuation between objectivity and subjectivity inherent to the circular causality loop described above.

Aleksei Turovski On the zoosemiotics of health and disease
abstract | view |  rights & permissions
The main feature of the signs of health in the animal habitus and behaviour can be characterised as the readiness to adequately (for a species) serve the need for impression (in animalistic elements of the Umwelt). The signs of disease, however multifarious and diverse, generally display certain lack of Umwelt-oriented attentiveness, alertness. Attention of deeply afflicted animals is strongly Innenwelt-oriented; and in some species a set of such signs, suggesting sickness or mortal disease is used as a set of traits in the mimicry of dying. The semiotic factors in health-disease relationships are apparently connected with intuition — like responses creating in the semiosphere a structure of Umwelt-Innenwelt polarized tensions, important in ecological and evolutional developments.

Peder Voetmann Christiansen Habit formation as symmetry breaking in the early universe
abstract | view |  rights & permissions
This paper tries to combine Peirce’s cosmology and metaphysics with current understanding in physics of the evolution of the universe, regarded as an ongoing semiotic process in a living cosmos. While the basic property of Life is viewed as an unexplainable Firstness inherent in the initial iconic state of the vacuous continuum we shall consider and exemplify two sign developing processes: (a) the transition from icon to index is considered as a symmetry breaking emergence of order actualising one among the possibilities of the iconic vacuum; (b) the transition from index to symbol, regarded as a habit formation — an adaptation of the surroundings to the order that has emerged. While the iconic state is characterized by fractal self-similarity the transitions to index and symbol are modelled by the mean field theory of second order phase transitions.

Luis Emilio Bruni Does “quorum sensing” imply a new type of biological information?
abstract | view |  rights & permissions
When dealing with biological communication and information, unifying concepts are necessary in order to couple the different “codes” that are being inductively “cracked” and defined at different emergent and “deemergent” levels of the biological hierarchy. In this paper I compare the type of biological information implied by genetic information with that implied in the concept of “quorum sensing” (which refers to a prokaryotic cell-to-cell communication system) in order to explore if such integration is being achieved. I use the Lux operon paradigm and the Vibrio fischeri – Euprymna scolopes symbiotic partnership to exemplify the emergence of informational contexts along the biological hierarchy (from molecules to ecologies). I suggest that the biosemiotic epistemological framework can play an integrative role to overcome the limits of dyadic mechanistic descriptions when relating the different emergent levels. I also emphasise that the realisation ofbiology as being a “science of sensing” and the new importance that is being ascribed to the “context” in experimental biology corroborate past claims ofbiosemioticians about a shift from a focus on information (as a material agent of causality) towards a focus on the world of signification.

Elling Ulvestad Biosemiotic knowledge — a prerequisite for valid explorations of extraterrestrial intelligent life
abstract | view |  rights & permissions
The scientific search for extraterrestrial intelligent life is probably one of the most ambitious projects ever taken in biology. The article discusses methodological problems associated with the search. It is emphasized that investigators of extraterrestrial intelligence, in contrast to investigators of terrestrial matters, have no valid pre-understanding of their subject matter. In this barren setting, utilization of semiotic knowledge is shown to be a prerequisite for achievement of valid data. Owing to methodological shortcomings, it is concluded that the NASA funded project SETI (Search for Extraterrestrial Intelligence) has little if any relevance for the detection of intelligent life in other worlds.

Andreas Weber Feeling the signs: The origins of meaning in the biological philosophy of Susanne K. Langer and Hans Jonas
abstract | view |  rights & permissions
This paper describes the semiotic approach to organism in two proto-biosemiotic thinkers, Susanne K. Langer and Hans Jonas. Both authors develop ideas that have become central terms of biosemiotics: the organism as subject, the realisation of the living as a closed circular self, the value concept, and, in the case of Langer, the concept of symbol. Langer tries to develop a theory of cultural symbolism based on a theory of organism as a self-realising entity creating meaning and value. This paper deals mainly with what both authors independently call “feeling”. Both authors describe “feeling” as a value-based perspective, established as a result of the active self interest manifested by an organic system. The findings of Jonas and Langer show the generation of a subject pole, or biosemiotic agent, under a more precise accent, as e.g. Uexküll does. Their ideas can also be affiliated to the interpretation of autopoiesis given by the late Francisco Varela (embodied cognition or “enactivism”). A synthesis of these positions might lead to insights how symbolic expression arises from biological conditions of living.

Peter Harries-Jones Where bonds become binds: The necessity for Bateson’s interactive perspective in biosemiotics
abstract | view |  rights & permissions
The paper examines important discrepancies between major figures influencing the intellectual development of biosemiotics. It takes its perspective from the work of Gregory Bateson. Unlike C. S. Peirce and J. von Uexküll, Bateson begins with a strong notion of interaction. His early writings were about reciprocity and social exchange, a common topic among anthropologists of the time, but Bateson’s approach was unique. He developed the notion of meta-patterns of exchange, and of the “abduction” of these metapatterns to a variety of other phenomena, in both biology and in game theory. Later, Bateson’s concept of ecology of mind, the product of interactive phenomena, was modified by a non-purposive cybernetics. Biosemiotics has yet to adopt Bateson’s interactive stance, which is absent from Peirce’s approach to communication, of Uexküll’s functional cycles, and of Hoffmeyer’s discussion of the relation between culture and environment. Rather than pursuing notions of appropriate “subjectivity” through changed ethical response to ecological conditions (Hoffmeyer’s discussion of empathy), the paper discusses the advantages of an approach that continues to focus on conditions of paradox and pathology. Specifically, Bateson’s resolution of the relation between culture and environment arises from situations of blocked communication where ecological bonds become binds.

Tom Ziemke On the epigenesis of meaning in robots and organisms: Could a humanoid robot develop a human(oid) Umwelt?
abstract | view |  rights & permissions
This paper discusses recent research on humanoid robots and thought experiments addressing the question to what degree such robots could be expected to develop human-like cognition, if rather than being pre-programmed they were made to learn from the interaction with their physical and social environment like human infants. A question of particular interest, from both a semiotic and a cognitive scientific perspective, is whether or not such robots could develop an experiential Umwelt, i.e. could the sign processes they are involved in become intrinsically meaningful to themselves? Arguments for and against the possibility of phenomenal artificial minds of different forms are discussed, and it is concluded that humanoid robotics still has to be considered “weak” rather than “strong AI”, i.e. it deals with models of mind rather than actual minds.

Claus Emmeche The chicken and the Orphean egg: On the function of meaning and the meaning of function
abstract | view |  rights & permissions
A central aspect of the relation between biosemiotics and biology is investigated by asking: Is a biological concept of function intrinsically related to a biosemiotic concept of sign action, and vice versa? A biological notion of function (as some process or part that serves some purpose in the context of maintenance and reproduction of the whole organism) is discussed in the light of the attempt to provide an understanding of life processes as being of a semiotic nature, i.e., constituted by sign actions. Does signification and communication in biology (e.g., intracellular communication) always presuppose an organism with distinct semiotic or quasi-semiotic functions? And, symmetrically, is it the case that functional relations are simply not conceivable without living sign action? The present note is just an introduction to a project aiming at elucidating the relations between biofunction and biosemiosis.
