Living organisms appear to have agency, the ability to act freely, and humans appear to have free will, the ability to rationally decide what to do. However, it is not clear how such properties can be produced by naturalistic processes, and there are indeed neuroscientific measurements that cast doubt on the existence of free will. Here I present a naturalistic theory of agency, consciousness, and free will. Elementary forms of agency evolved very early in the evolution of life, utilizing an (...) extension of the basic Darwinian scheme that combines and entangles deterministic and stochastic causation. The extension effectively produces an active form of causation, as well as meaning intrinsic to the organism. Consciousness arose when animals evolved advanced nervous systems and social lifestyles that enabled communication mutually affecting each animal’s intrinsic meaning. I argue that various forms of agency that subsequently arose in evolution, preconscious, conscious, intelligent, symbolic, and rational agency, still coexist in humans. This coexistence, combined with the fact that agency is not instantaneous but takes time to build up, makes simple interpretations of neuroscientific results on free will problematic. The conclusion of the study is that conscious free will, including a form of agent causation, is fully consistent with a naturalistic world-view and can be produced by the specific processes discussed. The result closely resembles existing approaches to life and mind that are inspired by phenomenology. (shrink)

The causal structure of Darwinian evolution by natural selection is investigated. Its basic scheme is reproduction resulting from a feedback loop driven by internal and external causes. Causation internal to the loop connects genotype, development, phenotype, and fitness, with environmental constraints on the latter preventing runaway reproduction. External causes driving the core loop are environmental change and genetic change. This basic causal structure is complicated by modern additions such as control of mutation rate, niche construction, interactions between evolution and development, (...) and epigenetic effects. In this article it is argued that at least one of these additions, control of mutation rate, produces an additional feedback loop incorporating a continual, targeted modulation of stochasticity, and thereby produces an unusual form of causation. This form of causation entangles deterministic and stochastic causation in such a way that it imposes, in effect, an active, goal-driven role on the organisms in a line of descent. The goal is defined by the factor driving the stochasticity, which must be regarded as an intrinsic estimate made implicitly by the organism of its own fitness. The estimator itself is an evolved property of the organism, and is aligned with the apparent goal-directedness of natural selection. (shrink)

The current article is the first in a series of review articles addressing biosemiotic terminology. The biosemiotic glossary project is inclusive and designed to integrate views of a representative group of members within the biosemiotic community based on a standard survey and related publications. The methodology section describes the format of the survey conducted in November–December 2013 in preparation of the current review and targeted on the terms ‘agent’ and ‘agency’. Next, I summarize denotation, synonyms and antonyms, with special emphasis (...) on the denotation of these terms in current biosemiotic usage. The survey findings include ratings of nine citations defining or making use of the two terms. I provide a summary of respondents’ own definitions and suggested term usage. Further sections address etymology, connotations, and related terms in English and other languages. A section on the notions’ mainstream meaning vs. their meaning in biosemiotics is followed by attempt at synthesis and conclusions. Although there is currently no consensus in the biosemiotic community on what constitutes a semiotic agent, i.e., an agent in the context of semiosis, most respondents agree that core attributes of an agent include goal-directedness, self-governed activity, processing of semiosis and choice of action, with these features being vital for the functioning of the living system in question. I agree that these four features are constitutive of biosemiotic agents, and stipulate that biosemiotic agents fall within three major categories, namely 1) sub-organismic biosemiotic agents, 2) organismic biosemiotic agents and 3) super-organismic biosemiotic agents.

Theses on the semiotic study of life as presented here provide a collectively formulated set of statements on what biology needs to be focused on in order to describe life as a process based on semiosis, or sign action. An aim of the biosemiotic approach is to explain how life evolves through all varieties of forms of communication and signification (including cellular adaptive behavior, animal communication, and human intellect) and to provide tools for grounding sign theories. We introduce the concept (...) of semiotic threshold zone and analyze the concepts of semiosis, function, umwelt, and the like as the basic concepts for theoretical biology. (shrink)

Terms loaded with informational connotations are often employed to refer to genes and their dynamics. Indeed, genes are usually perceived by biologists as basically ‘the carriers of hereditary information.’ Nevertheless, a number of researchers consider such talk as inadequate and ‘just metaphorical,’ thus expressing a skepticism about the use of the term ‘information’ and its derivatives in biology as a natural science. First, because the meaning of that term in biology is not as precise as it is, for instance, in (...) the mathematical theory of communication. Second, because it seems to refer to a purported semantic property of genes without theoretically clarifying if any genuinely intrinsic semantics is involved. Biosemiotics, a field that attempts to analyze biological systems as semiotic systems, makes it possible to advance in the understanding of the concept of information in biology. From the perspective of Peircean biosemiotics, we develop here an account of genes as signs, including a detailed analysis of two fundamental processes in the genetic information system (transcription and protein synthesis) that have not been made so far in this field of research. Furthermore, we propose here an account of information based on Peircean semiotics and apply it to our analysis of transcription and protein synthesis. (shrink)

From Cause to Causation presents both a critical analysis of C.S. Peirce's conception of causation, and a novel approach to causation, based upon the semeiotic of Peirce. The book begins with a review of the history of causation, and with a critical discussion of contemporary theories of the concept of `cause'. The author uncovers a number of inadequacies in the received views of causation, and discusses their historical roots. He makes a distinction between "causality", which is the relation between cause (...) and effect, and causation, which is the production of a certain effect. He argues that, by focusing on causality, the contemporary theories fatally neglect the more fundamental problem of causation. The author successively discusses Peirce's theories of final causation, natural classes, semeiotic, and semeiotic causation. Finally, he uses Peirce's semeiotic to develop a new approach to causation, which relates causation to our experience of signs. (shrink)

In the six decades since the publication of Julian Huxley's Evolution: The Modern Synthesis, spectacular empirical advances in the biological sciences have been accompanied by equally significant developments within the core theoretical framework of the discipline. As a result, evolutionary theory today includes concepts and even entire new fields that were not part of the foundational structure of the Modern Synthesis. In this volume, sixteen leading evolutionary biologists and philosophers of science survey the conceptual changes that have emerged since Huxley's (...) landmark publication, not only in such traditional domains of evolutionary biology as quantitative genetics and paleontology but also in such new fields of research as genomics and EvoDevo. Most of the contributors to Evolution—The Extended Synthesis accept many of the tenets of the classical framework but want to relax some of its assumptions and introduce significant conceptual augmentations of the basic Modern Synthesis structure—just as the architects of the Modern Synthesis themselves expanded and modulated previous versions of Darwinism. This continuing revision of a theoretical edifice the foundations of which were laid in the middle of the nineteenth century—the reexamination of old ideas, proposals of new ones, and the synthesis of the most suitable—shows us how science works, and how scientists have painstakingly built a solid set of explanations for what Darwin called the "grandeur" of life.

The field of semiotics is described as a general study of knowing. Knowing in a broad sense as a process that assumes (and includes) at least memory (together with heredity), anticipation, communication, meaningful information, and needs, is a distinctive feature of living systems. Sciences are distinguished accordingly into 'phi-sciences' (that use physicalist methodology) and 'sigma-sciences' (that use semiotic methodology). Jesper Hoffmeyer’s book Biosemiotics is viewed as an inquiry into the sigma-scientific approach to living systems.
