Comprehensive evaluation and study of man's theories and knowledge of genetical characteristics and the evolutionary processes.

In the past century, nearly all of the biological sciences have been directly affected by discoveries and developments in genetics, a fast-evolving subject with important theoretical dimensions. In this rich and accessible book, Paul Griffiths and Karola Stotz show how the concept of the gene has evolved and diversified across the many fields that make up modern biology. By examining the molecular biology of the 'environment', they situate genetics in the developmental biology of whole organisms, and reveal how the molecular (...) biosciences have undermined the nature/nurture distinction. Their discussion gives full weight to the revolutionary impacts of molecular biology, while rejecting 'genocentrism' and 'reductionism', and brings the topic right up to date with the philosophical implications of the most recent developments in genetics. Their book will be invaluable for those studying the philosophy of biology, genetics and other life sciences. (shrink)

Jean-Pierre Dupuy, prophet of what he calls "enlightened doomsaying," has long warned that modern society is on a path to self-destruction. In this book, he pleads for a subversion of this crisis from within, arguing that it is our lopsided view of religion and reason that has set us on this course. In denial of our sacred origins and hubristically convinced of the powers of human reason, we cease to know our own limits: our disenchanted world leaves us defenseless against (...) a headlong rush into the abyss of global warming, nuclear holocaust, and the other catastrophes that loom on our horizon. Reviving the religious anthropology of Max Weber, Emile Durkheim, and Marcel Mauss and in dialogue with the work of René Girard, Dupuy shows that we must remember the world's sacredness in order to keep human violence in check. A metaphysical and theological detective, he tracks the sacred in the very fields where human reason considers itself most free from everything it judges irrational: science, technology, economics, political and strategic thought. In making such claims, The Mark of the Sacred takes on religion bashers, secularists, and fundamentalists at once. Written by one of the deepest and most versatile thinkers of our time, it militates for a world where reason is no longer an enemy of faith. (shrink)

This article considers categorical perception (CP) as a crucial process involved in all sort of communication throughout the biological hierarchy, i.e. in all of biosemiosis. Until now, there has been consideration of CP exclusively within the functional cycle of perception–cognition–action and it has not been considered the possibility to extend this kind of phenomena to the mere physiological level. To generalise the notion of CP in this sense, I have proposed to distinguish between categorical perception (CP) and categorical sensing (CS) (...) in order to extend the CP framework to all communication processes in living systems, including intracellular, intercellular, metabolic, physiological, cognitive and ecological levels. The main idea is to provide an account that considers the heterarchical embeddedness of many instances of CP and CS. This will take me to relate the hierarchical nature of categorical sensing and perception with the equally hierarchical issues of the “binding problem”, “triadic causality”, the “emergent interpretant” and the increasing semiotic freedom observed in biological and cognitive systems.

It has become part of the accepted wisdom to say that the twentieth century was the century of physics and the twenty-first century will be the century of biology. Two facts about the coming century are agreed on by almost everyone. Biology is now bigger than physics, as measured by the size of budgets, by the size of the workforce, or by the output of major discoveries; and biology is likely to remain the biggest part of science through the twenty-first (...) century. Biology is also more important than physics, as measured by its economic consequences, by its ethical implications, or by its effects on human welfare. (shrink)

: The current difference in attitude toward germ-line enhancement in humans and nonhumans is unjustified. Society should be more cautious in modifying the genes of nonhumans and more bold in thinking about modifying our own genome. I identify four classes of arguments pertaining to germ-line enhancement: safety arguments, justice arguments, trust arguments, and naturalness arguments. The first three types are compelling, but do not distinguish between human and nonhuman cases. The final class of argument would justify a distinction between human (...) and nonhuman germ-line enhancement; however, this type of argument fails and, therefore, the discrepancy in attitude toward human and nonhuman germ-line enhancement is unjustified.

This paper argues that education itself, properly understood, is intimately concerned with an individual’s being in the world, and therefore is ineluctably environmental. This is guaranteed by the ecstatic nature of consciousness. Furthermore, it is argued that a central dimension of this environment with which ecstatic human consciousness is engaged, is that of nature understood as the ‘self-arising’. Nature, so conceived, is essentially other and is epistemologically mysterious, possessing its own normativity, agency, and intrinsic value. As such, engagement with nature (...) presents opportunities for consciousness quintessentially to go beyond itself, to be inspired and refreshed, and to receive non-anthropogenic standards in the form of intimations of what is fitting and what is not. It will be argued that these are fundamental to the orientation of human being, providing primordial intimations of the nature of reality and truth. Given their centrality to the idea of a person’s becoming educated, the elucidation of these and the issues to which they give rise must be central to the philosophy of education and in this sense it becomes deeply ecological.

Genetic interventions, which include transgenic engineering, gene editing, and other forms of genome modification aimed at altering the information “in” the genetic code, are rapidly increasing in power and scale. Biosemiotics offers unique tools for understanding the nature, risks, scope, and prospects of such technologies, though few in the community have turned their attention specifically in this direction. Bruni is an important exception. In this paper, I examine how we frame the concept of “side effects” that result from genetic interventions (...) and how the concept stands up to current perspectives of the role of organism activity in development. I propose that once the role of living systems in constructing and modifying the informational value of their various developmental resources is taken into account, the concept of a “side effect” will need to be significantly revised. Far from merely a disturbance brought about in a senseless albeit complex system, a biosemiotic view would take “side effects” as at least sometimes the organism’s active re-organization in order to accommodate or make use of novelty. This insight is nascent in the work of developmental plasticity and niche construction theory, but it is brought into sharper focus by the explicitly interpretive perspective offered by biosemiotics. Understanding the “side effects” of genetic interventions depends in part on being able to articulate when and where unexpected consequences are a result of semiotic activity at various levels within the system. While a semiotic interpretation of “side effects” puts into question the naive attitude that would see all unintended side effects as indications of disturbance in system functionality, it certainly does not imply that such side effects are of no concern for the viability of the organisms in the system. As we shall see, the fact that such interventions do not respect the translation of information that occurs in multi-level biological systems ensures that disruption is still likely. But it does unprivilege the human agent as the sole generator of meaning and information in the products of biotechnology, with important consequences on how we understand our relationship with other species.

In contrast to the traditional relational semiotics, biosemiotics decisively deviates towards dynamical aspects of signs at the evolutionary and developmental time scales. The analysis of sign dynamics requires constructivism to explain how new components such as subagents, sensors, effectors, and interpretation networks are produced by developing and evolving organisms. Semiotic networks that include signs, tools, and subagents are multilevel, and this feature supports the plasticity, robustness, and evolvability of organisms. The origin of life is described here as the emergence of (...) simple self-constructing semiotic networks that progressively increased the diversity of their components and relations. Primitive organisms have no capacity to classify and track objects; thus, we need to admit the existence of proto-signs that directly regulate activities of agents without being associated with objects. However, object recognition and handling became possible in eukaryotic species with the development of extensive rewritable epigenetic memory as well as sensorial and effector capacities. Semiotic networks are based on sequential and recursive construction, where each step produces components that are needed for the following steps of construction. Construction is not limited to repair and reproduction of what already exists or is unambiguously encoded, it also includes production of new components and behaviors via learning and evolution. A special case is the emergence of new levels of organization known as metasystem transition. Multilevel semiotic networks reshape the phenotype of organisms by combining a mosaic of features developed via learning and evolution of cooperating and/or conflicting subagents. (shrink)

Recent developments in biotechnology and genetic research are raising complex ethical questions concerning the legitimate scope and limits of genetic intervention. As we begin to contemplate the possibility of intervening in the human genome to prevent diseases, we cannot help but feel that the human species might soon be able to take its biological evolution in its own hands. 'Playing God' is the metaphor commonly used for this self-transformation of the species, which, it seems, might soon be within our grasp. (...) In this important new book, Jurgen Habermas - the most influential philosopher and social thinker in Germany today - takes up the question of genetic engineering and its ethical implications and subjects it to careful philosophical scrutiny. His analysis is guided by the view that genetic manipulation is bound up with the identity and self-understanding of the species. We cannot rule out the possibility that knowledge of one's own hereditary factors may prove to be restrictive for the choice of an individual's way of life and may undermine the symmetrical relations between free and equal human beings. In the concluding chapter - which was delivered as a lecture on receiving the Peace Prize of the German Book Trade for 2001 - Habermas broadens the discussion to examine the tension between science and religion in the modern world, a tension which exploded, with such tragic violence, on September 11th.

'...a challenging and useful book, both because it provokes a careful scrutiny of one's own basic ideas regarding evolutionary theory, and because it cuts across so many biological disciplines.' -The Quarterly Review of Biology 'In my view, this work exemplifies Theoretical Biology at its best...here is rampant speculation that is consistently based on cautious reasoning from the available data. Even more refreshing is the absence of sloganeering, grandstanding, and 'isms'.' -Biology and Philosophy 'Epigenetics is fundamental to understanding both development and (...) gene expression, and not surprisingly, evolutionary biologists have long been fascinated with its proper place in evolutionary theory...Enter Jablonka and Lamb, who provide a thoughtful review of the recent molecular literature and suggest a number of potential consequences.' -EvolutionSince first publication of this controversial book, much of the initial opposition to the ideas it contained has been replaced by a general, although often grudging, acceptance of them. Advances in knowledge, especially at the molecular level, have enhanced general awareness and interest in epigenetics and the evolution of systems that store and transmit information and put any of the authors' speculations on a more solid basis. This paperback edition contains a new Preface that sets out the major changes in the scientific world and in the authors' own thinking that have occurred since the book was published. A new Appendix provides a selected bibliography of the many books and articles about epigenetic inheritance and its role in evolution that have appeared since first publication. (shrink)

A re-issue of Gregory Bateson's classic work. It summarizes Bateson's thinking on the subject of the patterns that connect living beings to each other and to their environment.

Discusses mental processes, the role of humans in nature, experience, and the connection between myth, religion, and science.

This article deals with a critical examination of the philosophical underpinnings in regard to the development of technology in general, and biotechnology in particular. The text also focuses on the political and economic spectrum reflecting the socio-political consequences of the biotech revolution, and in that context also looks into the connections between the organization of biopolitics and biopower, and circumstances relative to the arts, sciences and social struggles, presenting biotech culture through a wide array of experiences and influences. This text (...) looks at how biotechnology is used for biopolitical purposes, in the sense of a political spectrum that reflects positions towards the social, economic and cultural consequences of the biotech revolution.

Synthetic biology can be understood as expanding the abilities and aspirations of genetic engineering. Nonetheless, whereas genetic engineering has been subject to criticism due to its endangering biodiversity, synthetic biology may actually appear to prove advantageous for biodiversity. After all, one might claim, synthesizing novel forms of life increases the numbers of species present in nature and thus ought to be ethically recommended. Two perspectives on how to spell out the conception of intrinsic value of biodiversity are examined in order (...) to assess this line of thought. At the cost of introducing two separate capacities of human knowledge acquisition, the ‘admiration stance’ turns out to reject outright the assumption of a synthetic species' intrinsic value and of an imperative to create novel species. The ‘kinship stance’ by contrast does ascribe value to both synthetic and natural species and organisms. Nonetheless, while from this perspective creating novel species may become an ethical demand under certain conditions, it favours changing organisms by getting in contact with them rather than synthesizing them. It is concluded that neither the admiration nor the kinship stance warrants a supposed general moral obligation to create novel species to increase biodiversity. (shrink)

Albert Schweitzer's Legacy for Education is the first book devoted to the study of the thought and deeds of Albert Schweitzer in relation to education. Schweitzer's life and work offer both inspiration and timely insights for educational thought and practice in the twenty-first century. Focusing on Schweitzer's central thought, "Reverence for Life," Rud assesses Schweitzer as a prophet for social and educational change. He develops the concept of practical reverence in education and describes the impact of Schweitzer's thought upon curriculum (...) development and the moral dimensions of teaching and learning in today's schools.

Biological evolution is often viewed narrowly as a change of morphology or allele frequency in a sequence of generations. Here I pursue an alternative informational concept of evolution, as preservation, advance, and emergence of functional information in natural agents. Functional information is a network of signs that are used by agents to preserve and regulate their functions. Functional information is preserved in evolution via complex interplay of copying and construction processes: the digital components are copied, whereas interpreting subagents together with (...) scaffolds, tools, and resources, are constructed. Some of these processes are simple and invariant, whereas others are complex and contextual. Advance of functional information includes improvement and modification of already existing functions. Although the genome information may change passively and randomly, the interpretation is active and guided by the logic of agent behavior and embryonic development. Emergence of new functions is based on the reinterpretation of already existing information, when old tools, resources, and control algorithms are adopted for novel functions. Evolution of functional information progressed from protosemiosis, where signs correspond directly to actions, to eusemiosis, where agents associate signs with objects. Language is the most advanced form of eusemiosis, where the knowledge of objects and models is communicated between agents. (shrink)
