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.

Krzysztof Chodasewicz (1982–2016) died young, but his publications strongly influenced the Polish scientific community in the field of the philosophy of life when life is understood as a biological process. This topic was an almost forgotten in Poland. It was Chodasewicz who, through the articles republished in the collection presented here, gave the Polish reader a picture of the current state of reflection on this issue. The articles are not only overviews of the contemporary positions; in each article Chodasewicz presents some of his new concepts. The main advantage of the published collection is a delicate form of making people aware of the range of possible views and problems, which in the subject of the essence and origin of life usually arouses great emotions and preliminary reservations. My paper is an overview of the topics and materials collected in the book, with my comments.

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).
