Giorgio Prodi (1928-1987) was an important Italian scientist who developed an original philosophy based on two basic assumptions: 1. life is mainly a semiotic phenomenon; 2. matter is somewhat a semiotic phenomenon. Prodi applies Peirce's cenopythagorean categories to all phenomena of life and matter: Firstness, Secondness, and Thirdness. They are interconnected meaning that the very ontology of the world, according to Prodi, is somewhat semiotic. In fact, when one describes matter as “made of” Firstness and Secondness, this means that matter ‘intrinsically’ implies semiotics (with Thirdness also being present in the world). At the very heart of Prodi’s theory lies a metaphysical hypothesis which is an ambitious theoretical gesture that places Prodi in an awkward position with respect to the customary philosophical tradition. In fact, his own ontology is neither dualistic nor monistic. Such a conclusion is unusual and weird, but much less unusual in present time than it was when it was first introduced. The actual resurgence of various “realisms” make Prodi’s semiotic realism much more interesting than when he first proposed his philosophical approach. What is uncommon, in Prodi perspective, is that he never separated semiotics from the materiality of the world. Prodi does not agree with the “standard” structuralist view of semiosis as an artificial and unnatural activity. On the contrary, Prodi believed semiosis (that is, the interconnection between Firstness, Secondness and Thirdness) lies at the very bottom of life. On one hand, Prodi maintains a strong realist stance; on the other, a realism that includes semiosis as ‘natural’ phenomena. This last view is very unusual because all forms, more or less, of realism exclude semiosis from nature but they frequently “reduce” semiosis to non-semiotic elements. According to Prodi, semiosis is a completely natural phenomenon.

This book presents programmatic texts on biosemiotics, written collectively by world leading scholars in the field (Deacon, Emmeche, Favareau, Hoffmeyer, Kull, Markoš, Pattee, Stjernfelt). In addition, the book includes chapters which focus closely on semiotic case studies (Bruni, Kotov, Maran, Neuman, Turovski).According to the central thesis of biosemiotics, sign processes characterise all living systems and the very nature of life, and their diverse phenomena can be best explained via the dynamics and typology of sign relations. The authors are therefore presenting a deeper view on biological evolution, intentionality of organisms, the role of communication in the living world and the nature of sign systems — all topics which are described in this volume. This has important consequences on the methodology and epistemology of biology and study of life phenomena in general, which the authors aim to help the reader better understand.

This book presents an interpretation of pharmaceutical, surgical and psychotherapeutic interventions based on a univalent metalanguage: biosemiotics. It proposes that a metalanguage for the physical, mental, social, and cultural aspects of health and medicine could bring all parts and aspects of human life together and thus shape a picture of the human being as a whole, made up from the heterogeneous images of the vast variety of sciences and technologies in medicine discourse. The book adopts a biosemiotics clinical model of thinking because, similar to the ancient principle of alchemy, tam ethice quam physice, everything in this model is physical as much as it is mental. Signs in the forms of vibrations, molecules, cells, words, images, reflections and rites conform cultural, mental, physical, and social phenomena. The book decodes healing, dealing with health, illness and therapy by emphasizing the first-person experience as well as objective events. It allows readers to follow the energy-information flows through and between embodied minds and to see how they form physiological functions such as our emotions and narratives.

This book invites readers to embark on a journey into the world of agency encompassing humans, other organisms, cells, intracellular molecular agents, colonies, populations, ecological systems, and artificial autonomous systems. We combine mechanistic and non-mechanistic approaches in the analysis of the function and evolution of organisms, their subagents, and multi-organism systems, and in this way offer a theoretical platform for integrating biosemiotics with both natural science and the humanities/social sciences. Agents are autonomous systems that incorporate knowledge on how to make sense of their environment and use it to achieve their goals. The functions of all agents are supported by mechanisms at the lowest level; however, the explanatory power of mechanistic analysis is not sufficient for complex agents. Non-mechanistic methods rely on the goal-directedness of agents whose dynamics follow self-stabilized dynamic attractors. The properties of attractors depend on stable or slowly changing factors, and such dependencies can be interpreted as sign relations if they are adaptive in nature. Agents can replace or redirect mechanisms on demand in order to preserve their functions; for performing higher-level semiotic functions, mechanisms are thus only means. We assume that mechanism and semiosis are not mutually exclusive, and that simple agents can interpret signs mechanistically. This assumption allows us to extend semiotic analysis to all agents, including ribosomes in cells, computers, and robots. This book challenges established traditions in natural science and the humanities/social sciences: semiotics no longer appears as restricted to humans and rational thinking, and biology is no longer limited to rely exclusively on mechanistic reasoning.

Diagrammatology investigates the role of diagrams for thought and knowledge. Based on the general doctrine of diagrams in Charles Peirce's mature work, Diagrammatology claims diagrams to constitute a centerpiece of epistemology. This book reflects Peirce's work on the issue in Husserl's contemporaneous doctrine of categorical intuition and charts the many unnoticed similarities between Peircean semiotics and early Husserlian phenomenology.

Combining research approaches from biology, philosophy and linguistics, the field of Biosemiotics proposes that animals, plants and single cells all engage in semiosis – the conversion of objective signals into conventional signs. This has important implications and applications for issues ranging from natural selection to animal behavior and human psychology, leaving biosemiotics at the cutting edge of the research on the fundamentals of life. Drawing on an international expertise, the book details the history and study of biosemiotics, and provides a state-of-the-art summary of the current work in this new field. And, with relevance to a wide range of disciplines – from linguistics and semiotics to evolutionary phenomena and the philosophy of biology – the book provides an important text for both students and established researchers, while marking a vital step in the evolution of a new biological paradigm.
