A consensus exists among contemporary philosophers of biology about the history of their field. According to the received view, mainstream philosophy of science in the 1930s, 40s, and 50s focused on physics and general epistemology, neglecting analyses of the 'special sciences', including biology. The subdiscipline of philosophy of biology emerged (and could only have emerged) after the decline of logical positivism in the 1960s and 70s. In this article, I present bibliometric data from four major philosophy of science journals (Erkenntnis, (...) Philosophy of Science, Synthese, and the British Journal for the Philosophy of Science), covering 1930-59, which challenge this view. (shrink)

Seeing human nature through the prism of grammar may seem rather unusual. I will argue that this is a symptom for a problem – in both discussions of human nature and grammar: Neither the theory of grammar has properly placed its subject matter within the context of an inquiry into human nature and speciation, nor have discussions of human nature properly assessed the significance of grammar.

Philosophy of biology, perhaps more than any other philosophy of science, is a discipline in flux. What counts as consensus and key arguments in certain areas changes rapidly.The publication of Contemporary Debates in Philosophy of Biology (2010 Wiley-Blackwell) is reviewed and is used as a catalyst to a discussion of the recent expansion of subjects and perspectives in the philosophy of biology as well as their diverse epistemological and methodological commitments.

Reductionism is a metaphysical thesis, a claim about explanations, and a research program. The metaphysical thesis reductionists advance (and antireductionists accept) is that all facts, including all biological facts, are fixed by the physical and chemical facts; there are no non-physical events, states, or processes, and so biological events, states and processes are “nothing but” physical ones. The research program can be framed as a methodological prescription which follows from the claim about explanations. Antireductionism does not dispute reductionism’s metaphysical claim, (...) but rejects the explanatory claim and so the methodological moral. To a first approximation what reductionists and antireductionists disagree about is whether explanations in functional biology can be or need to be explained by or completed or perhaps replaced by explanations in terms of molecular biology.i And this disagreement over the adequacy of explanations in functional biology drives a significant methodological disagreement with consequence for the research program of biology.

Evolution in its contemporary meaning in biology typically refers to the changes in the proportions of biological types in a population over time (see the entry on the concept of evolution to 1872 for earlier meanings). As evolution is too large of a topic to address thoroughly in one entry, the primary goal of this entry is to serve as a broad overview of contemporary issues in evolution with links to other entries where more in-depth discussion can be found. The (...) entry begins with a brief survey of definitions of evolution, followed by a discussion of the different modes of evolution and related philosophical issues, and ends with a summary of other topics in the philosophy of evolution focusing particularly on topics covered in this encyclopedia.

This paper considers the question of whether there is a human-animal or ‘anthropological difference'. It starts with a historical introduction to the project of philosophical anthropology. Section 2 explains the philosophical quest for an anthropological difference. Sections 3-4 are methodological and explain how philosophical anthropology should be pursued in my view, namely as impure conceptual analysis. The following two sections discuss two fundamental objections to the very idea of such a difference, biological continuity and Darwinist anti-essentialism. Section 7 discusses various (...) possible responses to this second objection - potentiality, normality and typicality. It ends by abandoning the idea of an essence possessed by all and only individual human beings. Instead, anthropological differences are to be sought in the realm of capacities underlying specifically human societies. The final section argues that if there is such a thing as the anthropological difference, it is connected to language. But it favours a more modest line according to which there are several anthropological differences which jointly underlie the gap separating us from our animal cousins. (shrink)

The Evolutionary Synthesis is often seen as a unification process in evolutionary biology, one which provided this research area with a solid common theoretical foundation. As such, neo-Darwinism is believed to constitute from this time onward a single, coherent, and unified movement offering research guidelines for investigations. While this may be true if evolutionary biology is solely understood as centred around evolutionary mechanisms, an entirely different picture emerges once other aspects of the founding neo-Darwinists’ views are taken into consideration, aspects (...) potentially relevant to the elaboration of an evolutionary worldview: the tree of life, the ontological distinctions of the main cosmic entities , the inherent properties of self-organizing matter, evolutionary ethics, and so on. Profound tensions and inconsistencies are immediately revealed in the neo-Darwinian movement once this broader perspective is adopted. This pluralism is such that it is possible to identify at least three distinct and quasi-incommensurable epistemological/metaphysical frameworks as providing a proper foundation for neo-Darwinism. The analysis of the views of Theodosius Dobzhansky, Bernhard Rensch, and Ernst Mayr will illustrate this untenable pluralism, one which requires us to conceive of the neo-Darwinian research agenda as being conducted in more than one research programme or research tradition at the same time.

‘Natural selection’ is, it seems, an ambiguous term. It is sometimes held to denote a consequence of variation, heredity, and environment, while at other times as denoting a force that creates adaptations. I argue that the latter, the force interpretation, is a redundant notion of natural selection. I will point to difficulties in making sense of this linguistic practise, and argue that it is frequently at odds with standard interpretations of evolutionary theory. I provide examples to show this; one example (...) involving the relation between adaptations and other traits, and a second involving the relation between selection and drift. (shrink)

In 1975, the English evolutionist William Donald Hamilton held in Brazil a series of lectures entitled “Population genetics and social behaviour”. The unpublished notes of these conferences—written by Hamilton and recently discovered at the British Library—offer an opportunity to reflect on some of the author’s ideas about evolution. The year of the conference is particularly significant, as it took place shortly after the applications of the Price equation with which Hamilton was able to build a model that included several levels (...) of selection. In this paper I mainly analyse the inaugural lecture in which Hamilton proposes a simple model to disprove the hypothesis supported by the British zoologist C. Vero Wynne-Edwards regarding mechanisms to prevent “over-exploitation of the food supply” in “the interests of the survival of the group”. The document presented here is of great historical interest. Not only because manuscript offers a model that—since it was intended for teaching purposes—had never before appeared in the published version, but also because of the general index of the lectures that accompanies it. The latter allows us to make some hypothetical considerations on the relationship and differences between kin-selection, group-selection and inclusive fitness that Hamilton wanted to present to the attentive, well-prepared audience of the foreign university that had invited him.

Genetic modification leads to several important moral issues. Up until now they have mainly been discussed from the viewpoint that only individual living beings, above all animals, are morally considerable. The standpoint that also collective entities such as species belong to the moral sphere have seldom been taken into account in a more thorough way, although it is advocated by several important environmental ethicists. The main purpose of this article is to analyze in more detail than often has been done (...) what the practical consequences of this ethical position would be for the use of genetic engineering on animals and plants. The practical consequences of the holistic standpoint (focused on collective entities) of Holmes Rolston, III, is compared with the practical consequences of the individualistic standpoints (focused on individual living beings) of Bernard E. Rollin and Philipp Balzer, Klaus Peter Rippe, and Peter Schaber, respectively. The article also discusses whether the claim that species are morally considerable is tenable as a foundation for policy decisions on genetic engineering. (shrink)

El concepto de público en Dewey permite reconciliar dos intuiciones en conflicto. Por un lado la idea de que la ciencia requiera de expertos entra en conflicto con la construcción de una sociedad democrática, y por la otra la idea de que las complejas sociedades del presente requieren para el desarrollo de la democracia de ciencia y tecnología. El concepto de público de Dewey permite superar ese conflicto en la medida en que permite superar la oposición tradicional en la filosofía (...) de la tecnología entre substantivistas y construccionistas.
