Theses on the semiotic study of life as presented here provide a collectively formulated set of statements on what biology needs to be focused on in order to describe life as a process based on semiosis, or sign action. An aim of the biosemiotic approach is to explain how life evolves through all varieties of forms of communication and signification (including cellular adaptive behavior, animal communication, and human intellect) and to provide tools for grounding sign theories. We introduce the concept (...) of semiotic threshold zone and analyze the concepts of semiosis, function, umwelt, and the like as the basic concepts for theoretical biology. (shrink)

Based on the conception of life and semiosis as co-extensive an attempt is given to classify cognitive and communicative potentials of species according to the plasticity and articulatory sophistication they exhibit. A clear distinction is drawn between semiosis and perception, where perception is seen as a high-level activity, an integrated product of a multitude of semiotic interactions inside or between bodies. Previous attempts at finding progressive trends in evolution that might justify a scaling of species from primitive to advanced levels (...) have not met with much success, but when evolution is considered in the light of semiosis such a scaling immediately catches the eye. The main purpose of this paper is to suggest a scaling of this progression in semiotic freedom into a series of distinct steps. The elleven steps suggested are: 1) molecular recognition, 2) prokaryote-eukaryote transformation, 3) division of labor in multicellular organisms, 4) from irritability to phenotypic plasticity, 5) sense perception, 6) behavioral choice, 7) active information gathering, 8) collaboration, deception, 9) learning and social intelligence, 10) sentience, 11) consciousness. In light of this, the paper finally discusses the conceptual framework for biosemiotic evolution. The evolution of biosemiotic capabilities does not take the form of an ongoing composition of simple signs into composite wholes. Rather, it takes the shape of the increasing subdivision and control of a primitive, holophrastic perception-action circuit already committed to “proto-propositions” reliably guiding action already in the most primitive species.

Introduction: Semiotic ScaffoldingA central idea in biosemiotic writings has been the idea of growth in semiotic freedom as a persistent trend in evolution . By semiotic freedom we mean the capacity of species or organisms to derive useful information by help of semiosis or, in other words, by processes of interpretation in the widest sense of this term. While even bacteria have a certain very limited ability to interpret cues in the medium this ability obviously becomes more developed in more (...) complex organisms, and is typically most developed in big-brained animals that are late arrivals at the evolutionary scene. The evolution of a richer semiotic capacity is of course only one among many strategies available in the evolutionary game. Yet, this particular strategy potentially ignites a self-perpetuating evolutionary dynamics, since each step taken by a species along this route potentially opens new agendas for further change:the more capable some species ar ..

Most bodies in this world do not have brains and the minority of animal species that do have brained bodies are descendents from species with more distributed or decentralized nervous systems. Thus, bodies were here first, and only relatively late in evolution did the bodies of a few species grow supplementary organs, brains, sophisticated enough to support a psychological life. Psychological life therefore from the beginning was embedded in and served as a tool for corporeal life. This paper discusses the (...) semiotically controlled dynamics of bodily existence that has allowed the evolution of these seemingly ‘unnatural’ mental and even linguistic kinds of species. It is shown how the skin, on the one hand, makes us belong in the world, and on the other hand, is part of the huge landscape of membranes across which the semiotic self incessantly must be reconstituted. The discussion moves on to the intracellular world of signal transduction through which the activity of single cells are put to service for bodily needs. The paper further considers the mechanisms behind homeostasis and the semiotics of the psycho-neuro-endocrine integration in the body. The concept of semiotic emergence is introduced and a holistic marker hypothesis for why some animals may have an experiential life is suggested. (shrink)

A sign is something that refers to something else. Signs, whether of natural or cultural origin, act by provoking a receptive system, human or nonhuman, to form an interpretant (a movement or a brain activity) that somehow relates the system to this "something else." Semiotics sees meaning as connected to the formation of interpretants. In a biosemiotic understanding living systems are basically engaged in semiotic interactions, that is, interpretative processes, and organic evolution exhibits an inherent tendency toward an increase in (...) semiotic freedom. Mammals generally are equipped with more semiotic freedom than are their reptilian ancestor species, and fishes are more semiotically sophisticated than are invertebrates. The evolutionary trend toward the production of life forms with an increasing interpretative capacity or semiotic freedom implies that the production of meaning has become an essential survival parameter in later stages of evolution.

The threshold from unicellularity to multicellularity has been crossed only in three major living domains in evolution with any lasting success. The hard problem was to create a multicellular self. Such a self is vulnerable to breakdown due to the unavoidable appearance of mutant anarchistic cells, and stringent semiotic scaffoldings had to emerge to prevent this. While a unicellular self may go on to live practically forever, the multicellular self most often must run through an individuation process ending in the (...) death of the individual. Due to basic differences in cells of plants, fungi and animals this individuation process poses very different challenges in the three kingdoms of plants, fungi and animals, and the solutions found to these differences are discussed. In the same time as multicellularity ushered life into the epoch of mortality it logically also led to the appearance of fertilization and thereby the need for a whole new set of elaborate semiotic scaffoldings. Multicellularity also opened the door to the formation symbiotic relations where cells with different genomes might collaborate or at least coexist inside the same body. All in all multicellularity led to an enormous diversification both of morphology space and the space of sensomotoric elaborations. New means for scaffolding of this expansion and diversification of possible life forms into functional patterns called for a corresponding growth in the space of semiotic tools and initiated a growth in semiotic freedom, that has continued to our days.

In strict opposition to the prevailing positivist conception of nature as senseless and deprived of meaning Jakob von Uexküll claimed that a certain planmässigkeit was operative in nature. This idea however might be taken to mean that organic evolution is not itself a creative process but a gradual, if majestic, unfolding of Nature's own master plan. Such an idea would threaten to restore determinism in the center of biological theory, and this would seriously contradict the vision of biosemiotics shared by (...) most of its proponents. It lies at the heart of biosemiotics and of Peircean cosmological philosophy that indeterminacy is primary, that “habit taking” or interpretation are real processes in the world, and therefore that belief in the law of necessity is unfounded. It is suggested that Uexküllian planmässigkeit is in fact reconcilable with a modern non-deterministic understanding. In a certain sense the Umwelten of animals have indeed developed in accordance to a natural planmässigkeit, but this is a plan that incessantly traps life in certain strategic choices and in the same time diversifies the dimensionality of options for dealing with these choices, i. e. “the adjacent possible” in the terms of Stuart Kauffman.

The belief in a world governed by natural law has meant that our ideas of good thinking have increasingly turned toward formalizable schemes, suitable to support ideas of consistency, accuracy, and disembodied clarity. The idea that thinking might be a bodily thing hasn't been much appreciated among philosophers of this tradition. Yet, we shall pursue this line of thought in this paper. It is suggested that knowledge is not something we have but something created in the very moment of use. (...) The same goes for other essential concepts such as for instance causality. Causality is seen as a human bodily experience. Causality is an experience, and from this fact follows that the Newtonian world must be turned upside down. The laws of gravity are not something "out-there" but something "in-here". (shrink)

This volume gathers scholars from ecology, biochemistry, evolutionary biology, cognitive science, anthropology and philosophy to discuss how Gregory Bateson's thinking might lead to a reframing of central problems in modern science.

Natural (non-cultivated) systems are nmed to economize their use of energy as much as possible, and thereby to produce minimal amounts of entropy. It is suggested that this has been obtained by optimizing the evolutionary creation of semiotic controls on all processes of life. As long as biological (ultimately photosynthetic) energy sources satisfied most human needs for energy consumption, these biosemiotic controls remained largely undisturbed, with the result that production systems remained sustainable. The industrial revolution instantiated a ruphure of this (...) balanced situation. The semiotic control function (S) would no longer match the size of the energy flow (E). In the industrial production system, energy flows have dramatically been increased, while the S component has not been taken care of. This has created a dangerously low S/E ratio, and it is suggested that this low S/E ratio constitutes a fundamental explanation of the environmental crisis. In order to restore a sustainable production system, we will now have to develop technological means for a strong increase in the S factor of the production system. It is suggested that this can be obtained through a development of considerate, gentle, and clever forms of biosemiotic technology. (shrink)
