    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 (...)

    Limitations on Applying Peircean Semeiotic. Biosemiotics as Applied Objective Ethics and Esthetics Rather Than Semeiotic.Tommi Vehkavaara - 2006 - Journal of Biosemiotics 1 (1):269-308.
    This paper explores the critical conditions of such semiotic realism that is commonly presumed in the so-called Copenhagen interpretation of biosemiotics. The central task is to make basic biosemiotic concepts as clear as possible by applying C.S. Peirce’s pragmaticist methodology to his own concepts, especially to those that have had a strong influence on the Copenhagian biosemiotics. It appears essential to study what kinds of observation the basic semiotic concepts are derived from. Peirce had two different derivations to the concept (...)

    From the Logic of Science to the Logic of the Living.Tommi Vehkavaara - 2007 - In Marcello Barbieri (ed.), Introduction to biosemiotics. Dordrecht, Netherlands: Springer. pp. 257-282.
    Biosemiotics belongs to a class of approaches that provide mental models of life since it applies some semiotic concepts in the explanation of natural phenomena. Such approaches are typically open to anthropomorphic errors. Usually, the main source of such errors is the excessive vagueness of the semiotic concepts used. If the goal of biosemiotics is to be accepted as a science and not as a priori metaphysics, it needs both an appropriate source of the semiotic concepts and a reliable method (...)
