In this paper I discuss recent debates concerning etiological theories of functions. I defend an etiological theory against two criticisms, namely the ability to account for malfunction, and the problem of structural doubles. I then consider the arguments provided by Bigelow and Pargetter (1987) for a more forward looking account of functions as propensities or dispositions. I argue that their approach fails to address the explanatory problematic for which etiological theories were developed.

In this paper I examine various ways in whichphilosophers have made connections between truth andnatural selection. I introduce several versions ofthe view that mechanisms of true belief generationarise as a result of natural selection and argue thatthey fail to establish a connection between truth andnatural selection. I then turn to scientific truthsand argue that evolutionary accounts of the origin ofscientific truth generation mechanisms also fail. Iintroduce David Hull's selectionist model ofscientific development and argue that his account ofscientific success does not (...) rely on connecting truthand natural selection. I argue that Hull's model,which severs the connection between truth andselection, can account for some aspects of scientificchange, but it still leaves us plenty of questionsabout what aspects of our individual cognitive make-upcontribute to scientific change and how they do so. I introduce an evolutionary approach to scientificcognition that shows how some of these questions canbe answered without making an explanatory appeal toselection for true belief generating mechanisms.

Appeals to human nature are ubiquitous, yet historically many have proven ill-founded. Why? How might frequent errors be remedied towards building a more robust and reliable scientific study of human nature? Our aim is neither to advance specific scientific or philosophical claims about human nature, nor to proscribe or eliminate such claims. Rather, we articulate through examples the types of errors that frequently arise in this field, towards improving the rigor of the scientific and social studies. We seek to analyze (...) such claims rhetorically, cognitively, and epistemically. Namely, how do we think about human nature? Claims about human nature, we show, are susceptible to widely exhibited deficits in cognitive tendencies such as framing, confirmation bias, satisficing, and teleological perspectives, as well as motivated reasoning. Such missteps foster methodological, empirical, and psychological mistakes and biases. Specifically, they promote the naturalizing error, whereby cultural ideology and values are projected onto an apparently objective description of nature. Concrete remedies are offered to aid scientists in conducting and reporting their research goals and findings more responsibly and effectively (relevant also to educators and other communicators who convey these findings publicly). Recommendations include acknowledging that human nature claims are often context-dependent, seeking multiple critical perspectives, and explicitly labeling uncertainties. (shrink)

I pose problems for the views that human nature should be the object of study in the social and behavioral sciences and that a concept of human nature is needed to guide research in these sciences. I proceed by outlining three research programs in the social sciences, each of which confronts aspects of human variation. Next, I present Elizabeth Cashdan and Grant Ramsey’s related characterizations of human nature. I go on to argue that the research methodologies they each draw on (...) are more productive resources for social scientists than their competing characterizations of human nature. (shrink)

When it comes to the metaethical task of explaining and making sense of what it is that we are doing while doing ethics, the subject of moral objectivity occupies an important and special place within that task. Thus, it is often agreed that being able to explain and justify the objective features of common moral practice is one of if not the most important task for any metaethical theory to undertake. In this dissertation, I tackle the issue of ethical objectivity (...) on behalf of metaethical constructivism. To be more precise, my aim is to make plausible, strengthen, and defend the constructivist original contribution to contemporary metaethics by developing a novel constructivist account on the objectivity of ethics. While the account that I develop herein presents a novel and independent approach to the subject of moral objectivity on behalf of constructivism, it also places itself between the two other positions within the constructivist camp that openly strive to secure ethical objectivity – namely Kantianism on the one hand, and the more recently developed Humean objectivist view on the other. It is for the latter reason that I call my own view the hybrid view. (shrink)

Research that involves the creation of animals with human-derived parts opens the door to potentially valuable scientific and therapeutic advances, yet invokes unsettling moral questions. Critics and champions alike stand to gain from clear identification and careful consideration of the strongest ethical objections to this research. A prevailing objection argues that crossing the human/nonhuman species boundary introduces inexorable moral confusion (IMC) that warrants a restriction to this research on precautionary grounds. Though this objection may capture the intuitions of many who (...) find this research unsettling, it relies on mistaken views of both biology and moral standing, ultimately distorting the morally relevant facts. We critically examine IMC, identify mistaken essentialist assumptions, and reframe ethical concerns. The upshot is a stronger line of objection that encourages a more inclusive and productive ethical discourse. (shrink)

There is a growing consensus that the traditional notion of human nature has failed and that human nature needs to be reconceptualized in light of our current scientific knowledge, including the knowledge gained in genetics and evolutionary biology. In “A Plea for Human Nature,” I highlighted this need, and I engaged in this reconceptualization effort, proposing a new notion of human nature, “the nomological notion of human nature” [Machery (Philosophical Psychology 21:321–330, 2008)]; for some more recent work, see Griffiths (Arts: (...) The Journal of the Sydney University Arts Association, 31:30–57, 2009), (2011); Stotz (Phenomenology and the Cognitive Sciences, 9:483–501, 2010); Samuels (Royal Institute of Philosophy Supplement, 70:1–28, 2012). In “Human Nature: The Very Idea,” Tim Lewens discusses the nomological notion of human nature critically. I am grateful for Lewens’s insightful article, and I examine Lewens’s criticisms in this brief response. (shrink)

Feminist philosophers of biology bring the tools of feminist theory, and in particular the tools of feminist philosophy of science, to investigations of the life sciences. While the critical examination of the categories of sex and gender (which will be explained below) takes a central place, the methods, ontological assumptions, and foundational concepts of biology more generally have also enjoyed considerable feminist scrutiny. Through such investigations, feminist philosophers of biology reveal the extent to which the theory and practice of particular (...) scientific disciplines and research programs (and, indeed, their philosophical study) are intertwined with both value judgments and social hierarchies.

El transhumanismo o el movimiento a favor del mejoramiento humano a través de la tecnología vive, actualmente, un momento álgido. Los avances en Inteligencia Artificial e ingeniería genética permiten que soñemos con seres capaces de vencer a la muerte y poseer capacidades hasta ahora desconocidas. Sin embargo, en este artículo veremos que no todo el mundo está de acuerdo con estas ideas y hay quienes consideran las promesas del transhumanismo más como pesadillas que como sueños. Estos son los conservadores. Los (...) conservadores consideran que las mejoras prometidas por el transhumanismo conllevarán el fin de la especie humana. Frente al transhumanismo, los conservadores defienden la conservación y protección de la esencia y la naturaleza humana. También se rebelan contra la manipulación ilimitada del ser humano y la limitación de estas prácticas a aquellas contenidas en la esencia humana. Todo ello les otorga cierta reminiscencia aristotélica en la que muchos de ellos se amparan y la cual vale la pena estudiar. (shrink)

George Kubler was one of the most important art historians of the twentieth century who is especially relevant today mainly for shifting the emphasis from high art to what is now known as ‘visual culture’ and for being the first genuinely global art historian. But what he has been most widely known for is the rejection of the biological metaphor of art—the general idea that artistic styles and movements grow, flower and then wither away. I argue that Kubler did not (...) in fact reject the biological metaphor of art but rather replaced a pre-Darwinian biological metaphor with a post-Darwinian one which bears remarkable similarities to Ernst Mayr’s concept of population thinking, developed at the same time that Kubler wrote The Shape of Time. Importantly, taking Kubler’s post-Darwinian biological metaphor seriously can help us to understand his distinctive art-historical explanatory scheme. (shrink)

Which domains of biology do philosophers of biology primarily study? The fact that philosophy of biology has been dominated by an interest for evolutionary biology is widely admitted, but it has not been strictly demonstrated. Here I analyse the topics of all the papers published in Biology & Philosophy, just as the journal celebrates its thirtieth anniversary. I then compare the distribution of biological topics in Biology & Philosophy with that of the scientific journal Proceedings of the National Academy of (...) Science of the USA, focusing on the recent period 2003–2015. This comparison reveals a significant mismatch between the distributions of these topics. I examine plausible explanations for that mismatch. Finally, I argue that many biological topics underrepresented in philosophy of biology raise important philosophical issues and should therefore play a more central role in future philosophy of biology.

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)

There are at least two senses in which human beings can be called “naturally artificial”: being adapted for creation of and participation in niche constructed environments, and being adapted for creation of and participation in such environments despite an exceptional indeterminacy in the details of the niche constructed environments themselves. The former puts human beings in a common category with many niche-constructing organisms while the latter is arguably distinctive of our species. I explain how this can be so by developing (...) an account of supporting concepts of complexity, contingency, and content-openness, and show how to defend the position against a common style of objection by a single comparative case study: hermit crabs and their shells versus humans and their movable dwellings. Finally, I consider evidence that such a feature is indeed species-typical and evolved in human populations. (shrink)

Philippa Foot and Rosalind Hursthouse, along with other philosophers, have argued for a metaethical position, the natural goodness approach, that claims moral evaluations are, or are on a par with, teleological claims made in the biological sciences. Specifically, an organism’s flourishing is characterized by how well they function as specified by the species to which they belong. In this essay, I first sketch the Neo-Aristotelian natural goodness approach. Second, I argue that critics who claim that this sort of approach is (...) inconsistent with evolutionary biology due to its species essentialism are in- correct. Third, I consider the prospects of understanding ethical normativity as a species of biological teleology claiming that this would be incompatible with our considered moral judgments. Fourth, after presenting gene-culture coevolution theory, I argue that the only way of reconciling naturalism and normativity in accordance with the natural goodness approach requires amending the selected effects function account to include cultural evolution. However, this approach, though not biologically reductionistic, still generates claims incompatible with our considered moral judgments. Finally, I end with a discussion of methodology and revisionistic moral theories. (shrink)

This essay is an exploratory reflection on a theme drawn from the work of Pierre Hadot and Juliusz Domański regarding “philosophy as a way of life.” I approach the matter from the naturalistic outlook of classic pragmatism and its own limitations. This approach stresses the possible improvement of the analysis of normativity by way of some neglected contributions regarding the nature of history and the evolution of Homo sapiens applied to the formation of the human self or person. I take (...) Hadot’s proposal seriously, therefore, as contributing to a mature conception of philosophy. But I deliberately restrict my own conjectures to naturalistic constraints, which begins to suggest an enlargement of pragmatism itself and an assessment of Hadot’s Greco-Roman and Christian themes.
