Nobel-price winning atmospheric chemist Paul Crutzen introduced in 2000 the concept of the Anthropocene as the name for the successor geological period to the Holocene. The Holocene started about 12,000 years ago and is characterized by the relatively stable and temperate climatic and environmental conditions that were conducive to the development of human societies. Until recently, human development had relatively little impact on the dynamics of geological time. Although disagreement exists over the exact birth date of the Anthropocene, it is (...) indisputable that the impact of human activity on the geo-climatic environment became more pronounced from the industrial revolution onwards, leading to a situation in which humans are now widely considered to have an eco-geologically critical impact on the earth's bio-physical system. The most obvious example is the accumulation of greenhouse gases like CO2and Methane (CH4) in the atmosphere and the changes this induces in climatic dynamics. Others are the growing homogenization of biodiversity as a result of human-induced species migration, mass extinction and bio-diversity loss, the manufacturing of new (sub-)species through genetic modification, or the geodetic consequences resulting from, for example, large dam construction, mining and changing sea-levels.

Transhumanism is a means of advocating a re-engineering of conditions that surround human existence at both ends. The problem set before us in this chapter is to inquire into what determined its appearance, in particular in the humanism it seeks to overcome. We look at the spirit of overcoming itself, and the impatience with the Self, in order to try to understand why it seeks a saving power in technology. We then consider how the evolutionary account of the production of (...) organisms does not set them against a perfect standard, but rather injects in them a contingency that seems to be near to the heart of the problem. We then try to assess the objective basis for improvements and manipulation of nature, and although we do not find it forbidden on all occasions, it seems that the criteria for such alterations are impossible to detach from a form of eugenics. We finally open a window toward a theological account of the problem, and find that the desire of autonomy and independence is inevitably going to be challenged by the Christian dogma of creation.

Review of André Ariew, Robert Cummins & Mark Perlman (eds.) *Functions: New Essays in the Philosophy of Psychology and Biology* (2002).

A scientific explanatory project, part-whole explanation, and a kind of science, part-whole science are premised on identifying, investigating, and using parts and wholes. In the biological sciences, mechanistic, structuralist, and historical explanations are part-whole explanations. Each expresses different norms, explananda, and aims. Each is associated with a distinct partitioning frame for abstracting kinds of parts. These three explanatory projects can be complemented in order to provide an integrative vision of the whole system, as is shown for a detailed case study: (...) the tetrapod limb. My diagnosis of part-whole explanation in the biological sciences as well as in other domains exploring evolved, complex, and integrated systems (e.g., psychology and cognitive science) cross-cuts standard philosophical categories of explanation: causal explanation and explanation as unification. Part-whole explanation is itself one essential aspect of part-whole science. (shrink)

Charles Darwin published his Origin of Species on November 24, 1859. Whatever hurdle the theory of natural selection faced in its struggle for acceptance, its impact on human self-images was almost immediate. Well before Darwin had the chance of applying the principle of natural selection to human origins—in his Descent of Man —his contemporaries quickly and rashly drew the infer–ence to man’s descent from the ape. Satirical magazines like Punch delighted in depicting Darwin with his imposing head on an apish (...) body. At the Oxford meeting of the British Association for the Advancement of Science, Bishop Wilberforce asked T. (shrink)

The epistemology of studies addressing questions about historical and prehistorical phenomena is a subject of increasing discussion among philosophers of science. A related field of inquiry that has yet to be connected to this topic is the epistemology of climate science. Branching these areas of research, I show how variety-of-evidence reasoning accounts for scientific inferences about the past by detailing a case study in paleoclimate reconstruction. This analysis aims to clarify the logic of historical inquiry in general and, by focusing (...) on a case study about climate change, it offers an epistemic account of a particular discipline that is of environmental and social importance.

The new discipline of exobiology formed from the intertwining of origin of life research with the search for life or its building blocks on other planets, from 1957-1973. The field was inherently highly interdisciplinary, yet it coalesced very quickly and was responsible in its first twenty years for numerous important contributions to twentieth century life science and planetary sciences such as climatology, the study of mass extinctions, etc. NASA played a very important role in catalyzing the rapid consolidation of exobiology, (...) both through research grants and through sponsored meetings that overcame disciplinary boundaries, bringing together scientists from diverse backgrounds. The presence of a handful of prominent senior scientists such as Joshua Lederberg, Melvin Calvin and Norman Horowitz helped gain credibility for exobiology, in the face of criticism and competition from existing life sciences disciplines. Tensions within the exobiology research community and between NASA-funded science and the academic research community are explored, as are such milestones of discipline formation as journals and professional societies.

‘There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don’t know we don’t know.’ —Donald Rumsfeld, 2003, President George W. Bush’s Secretary of Defense, on the subject of the U.S. government’s failure to discover weapons of mass destruction in Iraq.

The examples and concepts that Shoemaker cites are rather heterogeneous. Some distinctions need to be drawn. An optimality thesis involves not just an ordering of options, but a value judgment about them. So let us begin by distinguishing minimality from optimality. And the concept of minimality can play a variety of roles, among which I distinguish between extremum descriptions, statements hypothesizing an optimizing process, and methodological recommendations. Finally, I consider how the three categories relate to Shoemaker’s question that “Who is (...) optimizing: the scientist or nature?” . (shrink)

Sociobiology uses neo?Darwinism to make wide?ranging explanatory conjectures about man and society. The ?naturalism? of such an enterprise recommends it, but a thoroughgoing and Darwinian naturalism is compatible with a rejection of sociobiological conjectures. Retention of juvenile characteristics explains various human physical features and can be used to account for the playful and curiosity?driven nature of human intelligence. The malleable and hedonistic character of human sexuality is similarly explained. It has been argued (Wallace and latterly T. Nagel) that human intellectual (...) capacity transcends what is necessary for survival and so cannot be explained by natural selection. This wrongly supposes that all characteristics explained by Darwinism are explained as specifically selected for. Fears about biologically imposed limits to human understanding misrepresent intelligence as an aggregate of specifically adjusted capacities. Conceiving human intelligence as a product of neotenization frees us from the demand to explain everything as adaptive, and if the thesis is analogical, it is but one analogical conjecture against the plethora sociobiology requires.

This paper examines the strengths and weaknesses of one of science's most pervasive and flexible metaprinciples;optimalityis used to explain utility maximization in economics, least effort principles in physics, entropy in chemistry, and survival of the fittest in biology. Fermat's principle of least time involves both teleological and causal considerations, two distinct modes of explanation resting on poorly understood psychological primitives. The rationality heuristic in economics provides an example from social science of the potential biases arising from the extreme flexibility of (...) optimality considerations, including selective search for confirming vidence, ex post rationalization, and the confusion of prediction with explanation. Commentators are asked to reflect on the extent to which optimality is an organizing principle of nature, a set of relatively unconnected techniques of science, a normative principle for rational choice and social organization, a metaphysical way of looking at the world, or something else still.

According to simulationism, the function of episodic memory is not to remember the past, but to help construct representations of possible future episodes, by drawing together features from different experiential sources. This article suggests that the relationship between the traditional storehouse view, on which the function of memory is remembering, and the simulationist approach is more complicated than has been typically acknowledged. This is attributed, in part, to incorrect interpretations of what remembering on the storehouse view requires. Further, by appeal (...) to function pluralism, the article questions both the assumption that the traditional view and simulationism are inconsistent, and the simulationist’s inference to the best explanation strategy that is based upon this assumption. The article then provides an evaluation of the simulationist argument against the traditional view, and finds it in need of further support. (shrink)

One of the most dramatic techniques for constructing accounts of "undiscovery" or incompetence in science involves the manipulative deception—in some accounts, the "hoaxing"—of the putatively incompetent researcher, ostensibly as an experiment to evaluate his or her methodology and the soundness of his or her knowledge claims. In this article, the author examines five cases in which such deceptions have been employed, noting the patterns of argument that typically follow these deceptions and the factors that seem to determine the power of (...) these arguments. The author suggests that the "hoaxer" in such cases is most likely to be successful when his or her views about the targeted researcher's methodology and knowledge claims are orthodox with respect to his or her intended audience.

This paper explores the ways that Daniel C. Dennett’s bestselling 2006 book Breaking the Spell traffics in a set of distinctly American presumptions about the relationship between religion and science. In this Americanized atheism, religion is presumed to be a set of logically organized propositional beliefs–a misbegotten science in need of correction or elimination. I show that a convergent critique, drawing on both evolutionary theory and deconstruction, highlights the limitations of this approach. This convergence highlights the theme of accident in (...) both pluralist evolutionary biology and continental philosophy of religion. Thematizing accident opens up a new conversational space between a deconstructive approach to religion and postadaptationist evolutionary theory, with implications not only for a philosophical understanding of religion, but for new, postsecular atheisms.

Abstract One of the most important things that the Darwinian revolution affected is the previous teleological thinking. In particular, the attribution of functions to various entities of the natural world with explanatory pretensions. In this change, his theory of natural selection played an important role. We all agree on that, but the diversity and heterogeneity of the answers that try to explain what Darwin did exactly with functional biology are overwhelming. In this paper I will try to show how Darwin (...) modified previous functional biology. Pre-Darwinian naturalists did not hesitate to attribute functions in which, for example, the traits of one species were in the service of other species. I will try to show that this has consequences on the discussion regarding the nature of functional language, since the main approaches, the systemic and the etiological, do not adequately account for these changes and therefore do not account for the way functional biology regulates the kind of legitimate functions. I will outline a possible new solution to this problem: appropriate functional attributions in Darwinian functional biology could be regulated by a theory or a set of laws that provide the criteria for determining its fundamental concepts. -/- Resumen: Una de las cosas más importantes a las que la revolución darwiniana afectó es el pensamiento teleológico previo. En particular, la atribución de funciones a diversas entidades del mundo natural con pretensiones explicativas. En este cambio, su teoría de la selección natural desempeñó un papel importante. Todos estamos de acuerdo en ello, pero la diversidad y heterogeneidad de las respuestas que tratan de explicar lo que Darwin hizo exactamente con la biología funcional son abrumadoras. En este artículo intentaré mostrar cómo Darwin modificó la biología funcional anterior. Los naturalistas predarwinianos no dudaban en atribuir funciones en las que, por ejemplo, los rasgos de una especie estaban al servicio de otras especies. Intentaré mostrar que esto tiene consecuencias en la discusión sobre la naturaleza del lenguaje funcional, pues los principales enfoques, el sistémico y el etiológico, no dan cuenta adecuadamente de estos cambios y, por tanto, no dan cuenta de la forma en que la biología funcional regula el tipo de funciones legítimas. Esbozaré una posible nueva solución a este problema: las atribuciones funcionales apropiadas en la biología funcional darwiniana podrían estar reguladas por una teoría o un conjunto de leyes que proporcionen los criterios para determinar sus conceptos fundamentales. -/- .

. Despite the classical prohibition of moving from fact to value, encounter with the biodiversity and plenitude of being in evolutionary natural history moves us to respect life, even to reverence it. Darwinian accounts are value-laden and necessary for understanding life at the same time that Darwinian theory fails to provide sufficient cause for the historically developing diversity and increasing complexity on Earth. Earth is a providing ground; matter and energy on Earth support life, but distinctive to life is information (...) coded in the genetic molecules that superintends this matter-energy. Life is generated and regenerated in struggle, persists in its perishing. Such life is also a gift; nature is grace. Biologists and theologians join in celebrating and conserving the genesis on Earth, awed in their encounter with this creativity that characterizes our home planet. (shrink)

Through the last half of the nineteenth century and the first part of the twentieth, no scientist more vigorously defended Darwinian theory than the German Ernst Haeckel (1834–1919). More people learned of the new ideas through his voluminous publications, translated into numerous languages, than through any other source, including Darwin’s own writings. He enraged many of his contemporaries, especially among the religiously orthodox; and the enmity between evolutionary theory and religious fundamentalism that still burns brightly today may in large measure (...) be attributed to Haeckel’s unremitting attacks on the ingressions of religion into science. Though he retained a life-long friendship with and the support of Darwin, some in the scientific community who were critical of evolutionary theory—Emil Du Bois-Reymond, Rudolf Virchow, and Louis Agassiz, for instance—accused him of deception. That charge has been renewed in our time based on seemingly incontrovertible evidence. In a Science magazine article published in 1997, ‘‘Haeckel’s Embryos: Fraud Rediscovered,’’ Haeckel, was indicted of having intentionally misrepresented embryological development (Pennisi 1997). The article reported that the work of Michael Richardson and his colleagues demonstrated this malfeasance through a comparison of Haeckel’s illustrations of early-stage embryos with photographs of the same species at a comparable stage (see Fig. 1). The photos showed embryos of various species that differed among themselves and certainly from Haeckel’s images. The differences were striking and the implication obvious: fraudulent misrepresentation. Richardson, as quoted in the article, affirmed the charge: ‘‘It looks like it’s turning out to be one of the most famous fakes in biology’’. (shrink)

The explanatory role of natural selection is one of the long-term debates in evolutionary biology. Nevertheless, the consensus has been slippery because conceptual confusions and the absence of a unified, formal causal model that integrates different explanatory scopes of natural selection. In this study we attempt to examine two questions: (i) What can the theory of natural selection explain? and (ii) Is there a causal or explanatory model that integrates all natural selection explananda? For the first question, we argue that (...) five explananda have been assigned to the theory of natural selection and that four of them may be actually considered explananda of natural selection. For the second question, we claim that a probabilistic conception of causality and the statistical relevance concept of explanation are both good models for understanding the explanatory role of natural selection. We review the biological and philosophical disputes about the explanatory role of natural selection and formalize some explananda in probabilistic terms using classical results from population genetics. Most of these explananda have been discussed in philosophical terms but some of them have been mixed up and confused. We analyze and set the limits of these problems. (shrink)

Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every tenet of Darwinian theory – that it shows no genetic variation, could not exist in any intermediate forms, confers (...) no selective advantage, and would require more evolutionary time and genomic space than is available. We examine these arguments and show that they depend on inaccurate assumptions about biology or language or both. Evolutionary theory offers clear criteria for when a trait should be attributed to natural selection: complex design for some function, and the absence of alternative processes capable of explaining such complexity. Human language meets these criteria: Grammar is a complex mechanism tailored to the transmission of propositional structures through a serial interface. Autonomous and arbitrary grammatical phenomena have been offered as counterexamples to the position that language is an adaptation, but this reasoning is unsound: Communication protocols depend on arbitrary conventions that are adaptive as long as they are shared. Consequently, language acquisition in the child should systematically differ from language evolution in the species, and attempts to analogize them are misleading. Reviewing other arguments and data, we conclude that there is every reason to believe that a specialization for grammar evolved by a conventional neo-Darwinian process. (shrink)

Many studies about organizational experiences and theories converge today in the idea that the economic factor, most competitive now in the production of value, is the de-materialization of the economical and organizational processes. Immaterial factors (like knowledge, services, information, relationships, virtual transactions, etc.) are the competitive and crucial innovations for future competition and, at the same time, the most important criteria to rethinking and understanding the future organization. If this is true, we can realize that every person in organizations, every (...) personal history in organizations, or better the evolutionary uniqueness of every person in organizations, is the real depositary and bearer of this de-materialization.
