The debate over the relative importance of natural selection as compared to other forces affecting the evolution of organisms is a long-standing and central controversy in evolutionary biology. The theory of adaptationism argues that natural selection contains sufficient explanatory power in itself to account for all evolution. However, there are differing views about the efficiency of the adaptation model of explanation. If the adaptationism theory is applied, are energy and resources being used to their optimum? This book presents an up-to-date (...) view of this controversy and reflects the dramatic changes in our understanding of evolution that have occurred in the last twenty years. The volume combines contributions from biologists and philosophers, and offers a systematic treatment of foundational, conceptual, and methodological issues surrounding the theory of adaptationism. The essays examine recent developments in topics such as phylogenetic analysis, the theory of optimality and ess models, and methods of testing models. (shrink)

This response addresses the excellent responses to my book provided by Heather Douglas, Janet Kourany, and Matt Brown. First, I provide some comments and clarifications concerning a few of the highlights from their essays. Second, in response to the worries of my critics, I provide more detail than I was able to provide in my book regarding my three conditions for incorporating values in science. Third, I identify some of the most promising avenues for further research that flow out of (...) this interchange. (shrink)

Scholars have long debated how exactly Aristotle thinks that agents acquire the distinctivearchai(“principles” or “starting‐points”) that govern their practical reasoning. The debate has traditionally been dominated by anti‐intellectualists, who hold that for Aristotle all agents acquire theirarchaisolely through a process of habituation in the nonrational soul. Their traditional opponents, the intellectualists, focus their argument on the case of the virtuous person, arguing that in Aristotle’s view virtuous agents acquire theirarchaithrough a process of reasoning. I intervene in this debate in two (...) main ways: first, I press a heretofore underappreciated objection against anti‐intellectualism, that it is inconsistent with Aristotle’s account ofakrasia; and second, I urge that all sides in the debate would benefit from more sustained attention to Aristotle’s nonvirtuous character types. In the final section, I suggest that proper consideration of the full breadth of Aristotle’s account of character points in the direction of a new approach that I call “character pluralism,” according to which Aristotle’s moral psychology does not involve a single conception of psychic structure or moral development that is equally applicable to all character types.

Ludwig Wittgenstein's later philosophy continues to spark debate among theorists across the political spectrum. Much of the disagreement centres on the nature of rule-following, and the implications that it has for political thought and practice. In this paper, I explore a critical part of Wittgenstein's explanation of rule-following that is often overlooked: the ‘civic status of a contradiction’. I consider how the collective, conventional properties of rule-following practice shape language- and concept-use. I contend that debates over the political implications of (...) rule-following have tended to fixate on one dimension of Wittgenstein's work: social and epistemic emancipation. And I propose an alternative model of rule-following that harnesses the theoretical framework of self-realisation in order to help us to understand how we collectively follow and modify rules.

Interviews were conducted with 15 entrepreneurial feminists to explore how feminist values are enacted in opportunity recognition and organizational structures within the venture-creation process. Results suggest that opportunity recognition aligned with the needs and values of the entrepreneurial feminists. Opportunity construction was defined as ‘I am the market’, ‘building community with women like me’, ‘enabling others’, ‘do more with my life’, and ‘opportunity knocked’. Organizational structures and governance reflected cooperative, collaborative and ethical principles. Implications to feminist theory are discussed.

In ‘Two Dogmas of Empiricism’, Quine attacks the analytic/synthetic distinction and defends a doctrine that I call epistemological holism. Now, almost fifty years after the article’s appearance, what are we to make of these ideas? I suggest that the philosophical naturalism that Quine did so much to promote should lead us to reject Quine’s brief against the analytic/synthetic distinction; I also argue that Quine misunderstood Carnap's views on analyticity. As for epistemological holism, I claim that this thesis does not follow (...) from the logical point that Duhem and Quine made about the role of auxiliary assumptions in hypothesis testing, and that the thesis should be rejected.

Clinicians at quaternary centers see part of their mission as providing hope when others cannot. They tend to see sicker patients with more complex disease processes. Part of this mission is offering longshot treatment modalities that are unlikely to achieve their stated goal, but conceivably could. When patients embark on such a treatment plan, it may fail. Often treatment toward an initial goal continues beyond the point at which such a goal is feasible. We explore the progression of care from (...) longshot to fantasy using two pediatric cases. This progression may be differentiated into four distinct stages of care related to the potential of achieving the initial goals of care. Physicians are often ill prepared for the progression of treatments from a longshot hope to an unfeasible and, therefore, typically unjustified intervention. We present a structured approach to guide clinicians at referral institutions where these situations may be common. The transition of care from “longshot” to “fantasy” is an inherent part of quaternary care for the sickest of patients that has been underexplored. Physicians are often poorly equipped to approach that transition. We advocate this approach to the shift from longshot to fantasy with the belief that such a structured method will have multiple benefits, including: reduced suffering for the patient; decreased emotional burden on patient and family; decreased provider moral distress; increased likelihood of seeking high quality palliative care earlier; and provision of honest and straightforward information to patients and their families.

ABSTRACTA recent line of argument insists that replacing democracy with markets would improve social decision making due to markets’ superior use of knowledge. These arguments are flawed by unrealistic assumptions, unfair comparisons, and a neglect of the epistemic limits of markets. In reality, the epistemic advantages of markets over democracy are circumscribed and often illusory. A recognition of markets’ epistemic limits can, however, provide guidance for designing institutions in ways that capture the advantages of both.

The concept of fitness began its career in biology long before evolutionary theory was mathematized. Fitness was used to describe an organism’s vigor, or the degree to which organisms “fit” into their environments. An organism’s success in avoiding predators and in building a nest obviously contribute to its fitness and to the fitness of its offspring, but the peacock’s gaudy tail seemed to be in an entirely different line of work. Fitness, as a term in ordinary language (as in “physical (...) fitness”) and in its original biological meaning, applied to the survival of an organism and its offspring, not to sheer reproductive output (Paul ////; Cronin 1991). Darwin’s separation of natural from sexual selection may sound odd from a modern perspective, but it made sense from this earlier point of view. (shrink)

The Nature of Selection is a straightforward, self-contained introduction to philosophical and biological problems in evolutionary theory. It presents a powerful analysis of the evolutionary concepts of natural selection, fitness, and adaptation and clarifies controversial issues concerning altruism, group selection, and the idea that organisms are survival machines built for the good of the genes that inhabit them. "Sober's is the answering philosophical voice, the voice of a first-rate philosopher and a knowledgeable student of contemporary evolutionary theory. His book merits (...) broad attention among both communities. It should also inspire others to continue the conversation."-Philip Kitcher, Nature "Elliott Sober has made extraordinarily important contributions to our understanding of biological problems in evolutionary biology and causality. The Nature of Selection is a major contribution to understanding epistemological problems in evolutionary theory. I predict that it will have a long lasting place in the literature."-Richard C. Lewontin. (shrink)

The reference of the postmodern task of thinking is Auschwitz, the abyss and discontinuity separating us from the world of our ancestors. As inhabitants of Planet Auschwitz our point of reference lacks all transcendental warrants; it is not a non-referable reference which constitutes the abyss we must enter, endure, and in which our intellectual and cultural tradition must be transformed. The private/public transformations which constitute the texts of this book attempt to depart from the dystopic individuality and public life resulting (...) from business-as-usual after Auschwitz. The three parts of the book are progressive reworkings of traditional metaphysics as adapted and modified by a modernism that refuses to grapple with its complicity. It is precisely that complicity which postmodern thinking takes up in its attempt to signify otherwise than the easy modernist translations and images of tradition. Thus it is a series of uneasy images imaging otherwise but never apart from modernity that take us away from complicity toward a transformed tradition. The uneasy images of this book are photogrammic combinations of photographs and texts, mutual supplements, pulling tradition through the Event against the persistent and murderous forces of contemporary idolatry and repression.

In what follows, I’ll discuss both the metaphysics and the epistemology of supervenience from a probabilistic point of view. The first half of this paper will explore how supervenience claims are related to other issues; these will include the thesis that physics is causally complete, the claim that there are emergent properties, the idea that mental properties are causally efficacious, and the notion that there are scientific laws about supervenient properties that generalize over systems that deploy different physical realizations of (...) the properties in question. The second half will examine the question of how observational evidence can lend support to supervenience claims. This problem turns out to raise some surprisingly deep issues about the nature of hypothesis testing in science. (shrink)

God and numbers provide two challenges to metaphysical naturalism–the former if God exists and is a supernatural being, the latter if numbers exist and mathematical Platonism is true. Evolutionary theory is often described as having a commitment to naturalism, but this is doubly wrong. The theory is neutral on the question of whether God exists and mathematical evolutionary theory entails that numbers exist. The chapter develops the point about theistic neutrality by considering what evolutionary biologists mean when they say that (...) mutations are “unguided.” Evolutionary theory is logically compatible with deism and also with various interventionist theologies. In connection with mathematical evolutionary theory, the chapter discusses and criticizes the indispensability argument for mathematical Platonism developed by Quine and Putnam. The chapter criticizes their epistemological holism by considering ideas in Bayesian confirmation theory. (shrink)

I discuss two subjects in Samir Okasha’s excellent book, Evolution and the Levels of Selection. In consonance with Okasha’s critique of the conventionalist view of the units of selection problem, I argue that conventionalists have not attended to what realists mean by group, individual, and genic selection. In connection with Okasha’s discussion of the Price equation and contextual analysis, I discuss whether the existence of these two quantitative frameworks is a challenge to realism.

The current system of ethical review for medical research in the United Kingdom is changing from the current system involving large committees of 7–18 members reviewing every individual application to a system involving pre-review by small sub-committees of National Research Ethics Officers , who have a remit to approve studies if they believe there are no material ethical issues imposed by the research. The reliability of this new system depends on the reliability of the NREAs and in particular the ability (...) of small groups to effectively identify and appropriately assess the seriousness of all the material ethical issues that may be posed by an application. There is anecdotal evidence to suggest that many individual research ethics committee members have had experience of believing that a study presents no material ethical concerns, then on reaching the committee and discussing the application they realise that the committee feels it does present significant ethical concerns. If this is the case then this casts doubt on the reliability of NREAs or small groups to effectively identify ethically problematic research and appropriately respond to this to protect research participants. In this paper we describe a small questionnaire based piece of research carried out to assess how common this and other relevant experiences are. (shrink)

How should the concept of evidence be understood? And how does the concept of evidence apply to the controversy about creationism as well as to work in evolutionary biology about natural selection and common ancestry? In this rich and wide-ranging book, Elliott Sober investigates general questions about probability and evidence and shows how the answers he develops to those questions apply to the specifics of evolutionary biology. Drawing on a set of fascinating examples, he analyzes whether claims about intelligent (...) design are untestable; whether they are discredited by the fact that many adaptations are imperfect; how evidence bears on whether present species trace back to common ancestors; how hypotheses about natural selection can be tested, and many other issues. His book will interest all readers who want to understand philosophical questions about evidence and evolution, as they arise both in Darwin's work and in contemporary biological research. (shrink)

Recently, Edward Furton commented on an article that we published in Health Care Ethics USA concerning the philosophical and theological anthropology informing the discussion of appropriate care for individuals with gender dysphoria and intersex conditions. We appreciate the opportunity to clarify the points we made in that article, particularly the metaphysical mechanics underlying our contention that, as part of a unified human person, the human rational soul is sexed. We hope this more in-depth metaphysical explanation shows that Furton’s concern, while (...) valid insofar as our position may have needed clarifying, is nevertheless ill-founded with respect to our contention that actually existent human rational souls are sexed.

Game theory is often used to explain behavior. Such explanations often proceed by demonstrating that the behavior in question is a Nash equilibrium. Agents are in Nash equilibrium if each agent’s strategy maximizes her payoff given her opponents’ strategies. Nash equilibriums are fundamentally static, but it is usually assumed that equilibriums will be the outcome of a dynamic process of learning or evolution. This article demonstrates that, even in the most simple setting, this need not be true. In two-strategy games (...) with just a single equilibrium, a family of imitative learning dynamics does not lead to equilibrium. (shrink)

The role of values in scientific research has become an important topic of discussion in both scholarly and popular debates. Pundits across the political spectrum worry that research on topics like climate change, evolutionary theory, vaccine safety, and genetically modified foods has become overly politicized. At the same time, it is clear that values play an important role in science by limiting unethical forms of research and by deciding what areas of research have the greatest relevance for society. Deciding how (...) to distinguish legitimate and illegitimate influences of values in scientific research is a matter of vital importance.Recently, philosophers of science have written a great deal on this topic, but most of their work has been directed toward a scholarly audience. This book makes the contemporary philosophical literature on science and values accessible to a wide readership. It examines case studies from a variety of research areas, including climate science, anthropology, chemical risk assessment, ecology, neurobiology, biomedical research, and agriculture. These cases show that values have necessary roles to play in identifying research topics, choosing research questions, determining the aims of inquiry, responding to uncertainty, and deciding how to communicate information. Kevin Elliott focuses not just on describing roles for values but also on determining when their influences are actually appropriate. He emphasizes several conditions for incorporating values in a legitimate fashion, and highlights multiple strategies for fostering engagement between stakeholders so that value influences can be subjected to careful and critical scrutiny.

I consider three theses that are friendly to anthropomorphism. Each makes a claim about what can be inferred about the mental life of chimpanzees from the fact that humans and chimpanzees both have behavioral trait B and humans produce this behavior by having mental trait M. The first thesis asserts that this fact makes it probable that chimpanzees have M. The second says that this fact provides strong evidence that chimpanzees have M. The third claims that the fact is evidence (...) that chimpanzees have M. The third thesis follows from a plausible Reichenbachian model of how a common ancestor is probabilistically related to its descendants. The first two theses do not, and they have no general evolutionary justification. (shrink)

Reconstructing the Past seeks to clarify and help resolve the vexing methodological issues that arise when biologists try to answer such questions as whether human beings are more closely related to chimps than they are to gorillas. It explores the case for considering the philosophical idea of simplicity/parsimony as a useful principle for evaluating taxonomic theories of evolutionary relationships. For the past two decades, evolutionists have been vigorously debating the appropriate methods that should be used in systematics, the field that (...) aims at reconstructing phylogenetic relationships among species. This debate over phylogenetic inference, Elliott Sober observes, raises broader questions of hypothesis testing and theory evaluation that run head on into long standing issues concerning simplicity/parsimony in the philosophy of science. Sober treats the problem of phylogenetic inference as a detailed case study in which the philosophical idea of simplicity/parsimony can be tested as a principle of theory evaluation. Bringing together philosophy and biology, as well as statistics, Sober builds a general framework for understanding the circumstances in which parsimony makes sense as a tool of phylogenetic inference. Along the way he provides a detailed critique of parsimony in the biological literature, exploring the strengths and limitations of both statistical and nonstatistical cladistic arguments. (shrink)

Philosophers of science readily acknowledge that nonepistemic values influence the discovery and pursuit of scientific theories, but many tend to regard these influences as epistemically uninteresting. The present paper challenges this position by identifying three avenues through which nonepistemic values associated with discovery and pursuit in contemporary pollution research influence theory appraisal: (1) by guiding the choice of questions and research projects, (2) by altering experimental design, and (3) by affecting the creation and further investigation of theories or hypotheses. This (...) analysis indicates that the effects of these values are sufficiently complex and epistemically significant to merit further attention. †To contact the authors, please write to: Kevin Elliott, Department of Philosophy, University of South Carolina, Columbia, SC 29208; e‐mail: [email protected] .

Cooperation and the allocation of common resources are core features of social behavior. Games idealizing both interactions have been studied separately. But here, rather than examining the dynamics of the individual games, the interactions are combined so that players first choose whether to cooperate, and then, if they jointly cooperate, they bargain over the fruits of their cooperation. It is shown that the dynamics of the combined game cannot simply be reduced to the dynamics of the individual games and that (...) both cooperation and fair division are more likely in the combined game than in the constituent games taken separately.

A common view among statisticians is that convergence (which statisticians call consistency) is a necessary property of an inference rule or estimator. In this paper, this view is challenged by appeal to an example in which a rule of inference has a likelihood rationale but is not convergent. The example helps clarify the significance of the likelihood concept in statistical inference.
