Preface

pdf iconDownload PDF (59.3 KB)
pp. ix-

This volume is the product of talks we had about the important ways in which information shapes our understanding of biological organization, and more generally, of the difference between living and inanimate matter. It later occurred to us to broaden our conversation to include other researchers, both philosophers...

Introduction

pp. xi-xliii

The idea of information has become increasingly important in our efforts to understand the nature of biological organization. It is now generally recognized that information-related ideas play a key role in characterizing life at every organizational level. Familiar examples of these ideas include: how DNA codes for...

1. The Need for a Universal Definition of Life in Twenty-first-century Biology

pdf iconDownload PDF (116.2 KB)
pp. 3-23

Twentieth-century biology was based on and shaped by the concept of the gene, thus yielding extraordinary results, like the development of molecular biology and the modern synthesis of evolutionary theory (Keller 2000). The idea that processes in biological systems could be explained solely in terms of the...

2. Energy Coupling

pdf iconDownload PDF (243.9 KB)
pp. 25-51

As opposed to nonliving systems, living systems can reproduce as well as collect, process, and exchange information in order to control and direct energy and matter they receive from their environments. Living systems extract free energy from the sun, store it, and use it for sorting and motile activities. Chloroplasts...

3. Bioinformation as a Triadic Relation

pdf iconDownload PDF (239.8 KB)
pp. 55-90

Information is seen today not as a unitary concept, but as a family of concepts whose members lack any clear interconnection. The relationships of this family’s members with neighboring notions, such as knowledge, form, entropy, correlation, probability, meaning, order, organization, and complexity...

4. The Biosemiotic Approach in Biology: Theoretical Bases and Applied Models

pdf iconDownload PDF (591.9 KB)
pp. 91-129

Biosemiotics is a growing field that investigates semiotic processes in the living realm in an attempt to combine the findings of the biological sciences and semiotics. Semiotic processes are more or less what biologists have typically referred to as “signals,” “codes,” and “information processing” in biosystems, but these...

5. Problem Solving in the Life Cycles of Multicellular Organisms: Immunology and Cancer

pdf iconDownload PDF (126.9 KB)
pp. 131-156

The aim of the present inquiry is to incorporate our current understanding of information processing and problem solving in biological systems into an evolutionary perspective. Because our discussion centers on biological phenomena in multicellular organisms, and those especially relevant to human medicine, we also...

6. The Informational Nature of Biological Causality

pdf iconDownload PDF (109.6 KB)
pp. 157-175

Biological entities constitute highly complex systems. Since Darwin, this complexity has been thought to result from a long-term historical and collective process that goes far beyond the ontogenetic trajectories of individual living beings. In that framework, one in which biological activity takes place in a physically...

7. The Self-construction of a Living Organism

pdf iconDownload PDF (130.9 KB)
pp. 177-204

Recent developments in genetics and developmental biology have shown that the role of genetic information in living organisms is, in one sense, stronger than had been thought and, in another sense, weaker. Insofar as the living organism has certain material constituents — namely DNA, whose sequence...

8. Plasticity and Complexity in Biology: Topological Organization, Regulatory Protein Networks, and Mechanisms of Genetic Expression

pdf iconDownload PDF (175.1 KB)
pp. 205-250

This discussion is aimed first at studying some important aspects of the plasticity and complexity of biological systems and their links. We shall further investigate the relationship between the topological organization and dynamics of chromatin and chromosome, the regulatory proteins networks, and the mechanisms...

9. Decision Making in the Economy of Nature: Value as Information

pdf iconDownload PDF (159.6 KB)
pp. 253-287

Cognition, to use Reuven Dukas’s formula, is the set of “neuronal processes concerned with the acquisition, retention, and use of information” (Dukas 2004, 347). Decision making is one of the principal uses of that information. Classically, decision making is not a topic of discussion in biology and philosophy of biology...

10. Information Theory and Perception: The Role of Constraints, and What Do We Maximize Information About?

pdf iconDownload PDF (412.7 KB)
pp. 289-307

Because human and nonhuman primates are highly visual animals, an important step in understanding how their brains operate is to understand how they see: that is, how they transform the structured, colored, and dynamic pattern of light surrounding them into knowledge about the world they live in. Over the...

11. Attention, Information, and Epistemic Perception

pdf iconDownload PDF (221.0 KB)
pp. 309-352

Attention became a topic studied in experimental psychology by the end of the nineteenth century. With the subsequent development of psychology, interdisciplinary research on attention became an integral part of the cognitive and medical sciences (Posner and Raichle 1994; Parasuraman 1998; Wright...

12. Biolinguistics and Information

pdf iconDownload PDF (152.0 KB)
pp. 353-369

Modern (theoretical) linguistics was born half a century ago in the midst of what is often called the cognitive revolution. Noam Chomsky (1956, 1957), Morris Halle (1995, 2002), Eric Lenneberg (1967), and others distanced themselves from the then-dominant behaviorist paradigm, and reached back to earlier philosophical...

13. The Biology of Personality

pdf iconDownload PDF (156.1 KB)
pp. 371-406

The biology of personality can be described at multiple, complementary levels of analysis: descriptive, behavioral-genetic, neuroanatomical, neurochemical, situational, and behavioral-ecological. None of these individual levels of analysis separately presents a complete picture of the biology of personality...
