    Protosemiosis: Agency with Reduced Representation Capacity.Alexei A. Sharov & Tommi Vehkavaara - 2015 - Biosemiotics 8 (1):103-123.
    Life has semiotic nature; and as life forms differ in their complexity, functionality, and adaptability, we assume that forms of semiosis also vary accordingly. Here we propose a criterion to distinguish between the primitive kind of semiosis, which we call “protosemiosis” from the advanced kind of semiosis, or “eusemiosis”. In protosemiosis, agents associate signs directly with actions without considering objects, whereas in eusemiosis, agents associate signs with objects and only then possibly with actions. Protosemiosis started from the origin of life, (...)

    Why and How to Naturalize Semiotic Concepts for Biosemiotics.Tommi Vehkavaara - 2002 - Sign Systems Studies 30 (1):293-312.
    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 (...)

    Natural Self-Interest, Interactive Representation, and the Emergence of Objects and Umwelt.Tommi Vehkavaara - 2003 - Sign Systems Studies 31 (2):547-586.
    In biosemiotics, life and living phenomena are described by means of originally anthropomorphic semiotic concepts. This can be justified if we can show that living systems as self-maintaining far from equilibrium systems create and update some kind of representation about the conditions of their self-maintenance. The point of view is the one of semiotic realism where signs and representations are considered as real and objective natural phenomena without any reference to the specifically human interpreter. It is argued that the most (...)

    Constructive Aspects of Biosemiotics.Tommi Vehkavaara & Alexei Sharov - 2017 - Biosemiotics 10 (2):145-156.
    We argue that constructive approaches in epistemology and systems science, which are focused on normativity, knowledge, and communication of organisms and emphasize the primacy of activity, self-construction, and niche-construction in the cognitive agents, fit naturally to the both methodology and theory of biosemiotics. In particular, constructive view was already present in the works of the major precursors of biosemiotics: von Uexküll and Bateson, and to some extent Peirce. Biosemiotics has a chance to function as a mediating field in the theoretical (...)
