The aim of this paper is to discuss possible connections between the categories of mind and life. Some authors argue that life and mind are closely connected or even are two sides of the same phenomenon. I analyze and examine this thesis in the light of different approaches to defining life: the metabolic approach (which stresses the importance of self-maintenance and self-making) and the evolutionary approach (which focuses on evolution by natural selection). The first way of defining life is Maturana and Varela' conception of autopoiesis, the second is Korzeniewski's cybernetic definition of life and van Hateren's modified Darwinian definition of life. Especially interesting is the possibility of connecting mind and life in the evolutionary framework. The text does not provide exact results, but rather it proposes possible modes of thinking of the relation of these two categories.
Biology is a science on life. This definition, concise and most commonly used, is satisfactory for almost everybody. It is otherwise when one asks: What is life? Then it appears that no one feature can be indicated which distinguishes “the living” from “the non-living.” The author presents the sources of these difficulties and then gives his own attempt to solve the problem of definition of live—which is based on the idea of levels of the biological organization. In author’s view, to characterise the objects of research in biology we should apply not one concept of life (or of living organism) but three concepts: of organized biological matter (for the molecular and sub-cellular levels), of living organism (for the level of the specimen), and of life (for the sphere of phenomena which occur on the population-species-biocenotic level).
