Biology and the social sciences share an interest in phylogeny. Biologists know that living species are descended from past species, and use the pattern of similarities among living species to reconstruct the history of phylogenetic branching. Social scientists know that the beliefs, values, practices, and artifacts that characterize contemporary societies are descended from past societies, and some social science disciplines, linguistics and cross cultural anthropology for example, have made use of observed similarities to reconstruct cultural histories. Darwin appreciated that his (...) theory of descent with modification had many similarities of pattern and process to the already well developed field of historical linguistics. In many other areas of social science, however, phylogenetic reconstruction has not played a central role. (shrink)

The United States Court of Appeals for the Eighth Circuit held that ERISA did not preempt a Minnesota tort claim alleging fraud and negligent misrepresentation against primary-care physicians who failed to disclose their financial incentives to minimize specialist referrals. The original action was filed in state court after the plaintiff's husband died of heart failure, alleging that his family doctors had assured him that referral to a cardiologist was unnecessary. The plaintiff filed a wrongful death suit against the doctors, their (...) clinic, and her husband's HMO. Her complaint against the HMO alleged that certain financial incentives built into the HMO-physician contract were designed to minimize referrals to specialists. The HMO removed the case to the District of Minnesota, contending that ERISA preempted the plaintiff's wrongful death claim. (shrink)

We are encouraged by the attention paid to fundamental aspects relating to the interpersonal functions of emotion. In continuing this discussion, we consider two arguments used to distinguish social referencing and social appraisal, namely the role of ostension and the absence of prior appraisals of the individual. We contend that neither element is essential to social referencing.

Humans hunt and kill many different species of animals, but whales are our biggest prey. In the North Atlantic, a male long-fi nned pilot whale (Globiceph- ala melaena), a large relative of the dolphins, can grow as large as 6.5 meters and weigh as much as 2.5 tons. As whales go, these are not particularly large, but there are more than 750,000 pilot whales in the North Atlantic, traveling in groups, “pods,” that range from just a few individuals to a (...) thousand or more. Each pod is led by an individual known as the “pilot,” who appears to set the course of travel for the rest of the group. This pilot is both an asset and a weakness to the pod. The average pilot whale will yield about a half ton of meat and blubber, and North Atlantic societies including Ireland, Iceland, and the Shetlands used to manipulate the pilot to drive the entire pod ashore. In the Faroe Islands, a group of 18 grassy rocks due north of Scotland, pilot whale hunts have continued for the last 1200 years, at least. The permanent residents of these islands, the Faroese, previously killed an average of 900 whales each year, yielding about 500 tons of meat and fat that was consumed by local residents. Hunts have declined in recent years. From 2001 to 2005, about 3400 whales were killed, yielding about 890 metric tons of blubber and 990 metric tons of meat. The whale kill, or grindadráp in the Faroese language, begins when a fi shing boat spots a pod close enough to a suitable shore, on a suitably clear day. A single boat, or even a small group of fi shermen, is not suffi cient to trap a.. (shrink)

The epistemological premises and scientific viability of Stoffregen & Bardy's ecological perspective are evaluated by analyzing the concept of direct perception of global invariants vis-à-vis (1) behavioral evidence that perception is based on the integration of modal sources of information and (2) neurophysiological aspects of the integration of sensory signals.

Despite its uniform appearance, the cerebellar cortex is highly heterogeneous in terms of structure, genetics and physiology. Purkinje cells (PCs), the principal and sole output neurons of the cerebellar cortex, can be categorized into multiple populations that differentially express molecular markers and display distinctive physiological features. Such features include action potential rate, but also their propensity for synaptic and intrinsic plasticity. However, the precise molecular and genetic factors that correlate with the differential physiological properties of PCs remain elusive. In this (...) article, we provide a detailed overview of the cellular mechanisms that regulate PC activity and plasticity. We further perform a pathway analysis to highlight how molecular characteristics of specific PC populations may influence their physiology and plasticity mechanisms. (shrink)

Androgens (testosterone), acting via the androgen receptor (AR) a nuclear transcription factor, regulate male sexual development and body composition. In addition, AR expression plays an important role in the proliferation of human prostate cancer and confers a better prognosis in breast cancer. AR mRNA stability is central to the regulation of AR expression in prostate and breast cancer cells, and recent studies have demonstrated binding by members of the ELAV/Hu and poly(C) RNA‐binding protein families to a highly conserved UC‐rich element (...) in the 3′‐untranslated region of AR mRNA, with functional impact on AR protein expression. Remarkably, a CAG trinucleotide repeat in exon 1 of the AR, the length of which has been linked to prostate cancer survival, is also a target for multiple RNA‐binding proteins from a variety of human and murine tissues. In this review, we will detail the current knowledge of the mechanisms involved in regulating AR mRNA stability, the nature, potential role and structural biology of several novel AR mRNA–protein interactions, and the implications for novel therapeutics in human prostate cancer.

The authors offer a fresh look at the debate about the use of assisted nutrition and hydration in advanced dementia. The philosophical and ethical issues are presented. The importance of distinguishing basic care from medical acts is explained. A key question is addressed: Does ANH nourish and hydrate the patient with dementia? The ANH debate is placed in its cultural context and contrasted with the Catholic response. A clinical analysis of the evidence for benefit and harm of ANH in advanced (...) dementia is given. The authors point out the lack of hard evidence against ANH, discuss questions that need further clinical research, and argue that there is sufficient evidence for a presumption, in principle, in favor of ANH in patients with advanced dementia.

Alan C. LoveDarwinian calisthenicsAn athlete engages in calisthenics as part of basic training and as a preliminary to more advanced or intense activity. Whether it is stretching, lunges, crunches, or push-ups, routine calisthenics provide a baseline of strength and flexibility that prevent a variety of injuries that might otherwise be incurred. Peter Bowler has spent 40 years doing Darwinian calisthenics, researching and writing on the development of evolutionary ideas with special attention to Darwin and subsequent filiations among scientists exploring (...) evolution . Therefore, we would expect that when Bowler engages in a counterfactual history—imagining a world without Darwin—he is able to avoid historical injury and generate novel insights. My assessment is that the results are mixed. Before we can see why, it is necessary to walk briskly through the main contours of his argument.Bowler begins with an apologia for a counterfactual appr .. (shrink)

Progress Unchained reinterprets the history of the idea of progress using parallels between evolutionary biology and changing views of human history. Early concepts of progress in both areas saw it as the ascent of a linear scale of development toward a final goal. The 'chain of being' defined a hierarchy of living things with humans at the head, while social thinkers interpreted history as a development toward a final paradise or utopia. Darwinism reconfigured biological progress as a 'tree of life' (...) with multiple lines of advance not necessarily leading to humans, each driven by the rare innovations that generate entirely new functions. Popular writers such as H. G. Wells used a similar model to depict human progress, with competing technological innovations producing ever-more rapid changes in society. Bowler shows that as the idea of progress has become open-ended and unpredictable, a variety of alternative futures have been imagined. (shrink)

Although much has been written about the vigorous debates over science and religion in the Victorian era, little attention has been paid to their continuing importance in early twentieth-century Britain. Reconciling Science and Religion provides a comprehensive survey of the interplay between British science and religion from the late nineteenth century to World War II. Peter J. Bowler argues that unlike the United States, where a strong fundamentalist opposition to evolutionism developed in the 1920s (most famously expressed in the (...) Scopes "monkey trial" of 1925), in Britain there was a concerted effort to reconcile science and religion. Intellectually conservative scientists championed the reconciliation and were supported by liberal theologians in the Free Churches and the Church of England, especially the Anglican "Modernists." Popular writers such as Julian Huxley and George Bernard Shaw sought to create a non-Christian religion similar in some respects to the Modernist position. Younger scientists and secularists—including Rationalists such as H. G. Wells and the Marxists—tended to oppose these efforts, as did conservative Christians, who saw the liberal position as a betrayal of the true spirit of their religion. With the increased social tensions of the 1930s, as the churches moved toward a neo-orthodoxy unfriendly to natural theology and biologists adopted the "Modern Synthesis" of genetics and evolutionary theory, the proposed reconciliation fell apart. Because the tensions between science and religion—and efforts at reconciling the two—are still very much with us today, Bowler's book will be important for everyone interested in these issues.

Proper functionalism explicates epistemic warrant in terms of the function and normal functioning of the belief-forming process. There are two standard substantive views of the sources of functions in the literature in epistemology: God (intelligent design) or Mother Nature (evolution by natural selection). Both appear to confront the Swampman objection: couldn’t there be a mind with warranted beliefs neither designed by God nor the product of evolution by natural selection? Is there another substantive view that avoids the Swampman objection? There (...) are two. The first is the generalized selected-effects theory of functions. The second is the organizational theory of functions. Both, however, require some history to assign functions, for both are etiological theories of functions: past effects help explain current function. Swampman can then acquire functions, perhaps soon after creation, though he has none at the moment of inception. (shrink)

Epistemic defeat is standardly understood in either evidentialist or responsibilist terms. The seminal treatment of defeat is an evidentialist one, due to John Pollock, who famously distinguishes between undercutting and rebutting defeaters. More recently, an orthogonal distinction due to Jennifer Lackey has become widely endorsed, between so-called doxastic (or psychological) and normative defeaters. We think that neither doxastic nor normative defeaters, as Lackey understands them, exist. Both of Lackey’s categories of defeat derive from implausible assumptions about epistemic responsibility. Although Pollock’s (...) evidentialist view is superior, the evidentialism per se can be purged from it, leaving a general structure of defeat that can be incorporated in a reliabilist theory that is neither evidentialist nor responsibilist in any way.

Propositionalism explains the nature of knowledge-how as follows: P: To know how to ϕ is to stand in a special propositional attitude relation to propositions about how to ϕ. To know how to ride a bike is to have the required propositional attitude to propositions about how to do so. Dispositionalism offers an alternative view.D: To know how to ϕ is to stand in a behavioral-dispositional relation, a being-able-to relation, to ϕ-ing. To know how to ride a bike is to (...) have an ability to do so in the form of a complex disposition to behave in ways that constitute bike riding. Objectualism presents a third option.O: To know how to ϕ is to stand in a non-propositional, non-behavioral-dispositional objective attitude relation to a way of j-ing. To know how to ride a bike is to have an objectual attitude, perhaps a form of knowledge of, to a way of doing so.Dispositionalism is often dismissed on the basis of two criticisms designed to show its shortcomings relative to Propositionalism and Objectualism. According to the Epistemic Improvement Objection, Dispositionalism cannot account for the fact that gaining knowledge-how is an improvement in our epistemic state. According to the Modified Ability Objection, it cannot account for the fact that being able to do something is neither necessary nor sufficient for knowing how to do it. I develop a form of Dispositionalism, the Special Ability View, that avoids both objections. (shrink)

A history of science text imagining how evolutionary theory and biology would have been understood if Darwin had never published his "Origin of Species" and other works.--publisher summary.

This paper investigates the tenability of wavefunction realism, according to which the quantum mechanical wavefunction is not just a convenient predictive tool, but is a real entity figuring in physical explanations of our measurement results. An apparent difficulty with this position is that the wavefunction exists in a many-dimensional configuration space, whereas the world appears to us to be three-dimensional. I consider the arguments that have been given for and against the tenability of wavefunction realism, and note that both the (...) proponents and the opponents assume that quantum mechanical configuration space is many-dimensional in exactly the same sense in which classical space is three-dimensional. I argue that this assumption is mistaken, and that configuration space can be taken as three-dimensional in a relevant sense. I conclude that wavefunction realism is far less problematic than it has been taken to be. Introduction Non-separability The instantaneous solution The dynamical solution Invariance What is configuration space, anyway? Conclusion. (shrink)

Robert Audi’s Seeing, Knowing, and Doing argues that knowledge does not entail justification, given a broadly externalist conception of knowledge and an access internalist conception of justification, where justification requires the ability to cite one’s grounds or reasons. On this view, animals and small children can have knowledge while lacking justification. About cases like these and others, Audi concludes that knowledge does not entail justification. But the access internalist sense of “justification” is but one of at least two ordinary senses (...) of the term. On a broader or looser sense, “justification” means “being in the right” where that involves meeting a standard or norm. I argue that the beliefs of animals and small children can then meet standards or norms associated with truth and knowledge such that their beliefs may count as justified in this broader or looser sense. I then question whether knowledge fails to entail justification on this broader sense. (shrink)

Metaphysicians should pay attention to quantum mechanics. Why? Not because it provides definitive answers to many metaphysical questions-the theory itself is remarkably silent on the nature of the physical world, and the various interpretations of the theory on offer present conflicting ontological pictures. Rather, quantum mechanics is essential to the metaphysician because it reshapes standard metaphysical debates and opens up unforeseen new metaphysical possibilities. Even if quantum mechanics provides few clear answers, there are good reasons to think that any adequate (...) understanding of the quantum world will result in a radical reshaping of our classical world-view in some way or other. Whatever the world is like at the atomic scale, it is almost certainly not the swarm of particles pushed around by forces that is often presupposed. This book guides readers through the theory of quantum mechanics and its implications for metaphysics in a clear and accessible way. The theory and its various interpretations are presented with a minimum of technicality. The consequences of these interpretations for metaphysical debates concerning realism, indeterminacy, causation, determinism, holism, and individuality are explored in detail, stressing the novel form that the debates take given the empirical facts in the quantum domain. While quantum mechanics may not deliver unconditional pronouncements on these issues, the range of possibilities consistent with our knowledge of the empirical world is relatively small-and each possibility is metaphysically revisionary in some way. This book will appeal to researchers, students, and anybody else interested in how science informs our world-view. (shrink)

Stewart Cohen has recently presented solutions to two forms of what he calls “The Problem of Easy Knowledge” (“Basic Knowledge and the Problem of Easy Knowledge,” Philosophy and Phenomenological Research, LXV, 2, September 2002, pp. 309‐329). I offer alternative solutions. Like Cohen's, my solutions allow for basic knowledge. Unlike his, they do not require that we distinguish between animal and reflective knowledge, restrict the applicability of closure under known entailments, or deny the ability of basic knowledge to combine with self‐knowledge (...) to provide inductive evidential support. My solution to the closure version of the problem covers a variation on the problem that is immune to Cohen's approach. My response to the bootstrapping version presents reasons to question whether the problem case, as Cohen presents it, is even possible, and, assuming it is, my solution avoids a false implication of Cohen's own. The key to my solutions for both versions is the distinction between an inference's transferring epistemic support, on the one hand, and its not begging the question against skeptics, on the other.

The norm of assertion, to be in force, is a social norm. What is the content of our social norm of assertion? Various linguistic arguments purport to show that to assert is to represent oneself as knowing. But to represent oneself as knowing does not entail that assertion is governed by a knowledge norm. At best these linguistic arguments provide indirect support for a knowledge norm. Furthermore, there are alternative, non-normative explanations for the linguistic data (as in recent work from (...) Van Elswyk). Direct arguments would rely on normative judgments about the permissibility or impermissibility of assertions with and without the speaker knowing the content asserted. John Turri's work experimental results purport to show that our norm of assertion is factive, and probably knowledge. But as a number of recent experimentalists (Kneer, Reuter and Broessel, Marsili and Wiegmann) have shown, Turri's results rely on the problemmatic use of 'should' as in 'Maria should assert that she owns a 1990 watch.' Correcting for this, these experimentalists provide strong evidence that our norm of assertion is not factive. The standard reply to evidence like this from the assertion of unlucky falsehoods is the excuse maneuver. But Marsili and Wiegmann, following Turri's protocol for testing for excuse validation, show that participants who judge that assertions unlucky falsehoods are permissible are not guilty of excuse validation. Given our current understanding of the experimental evidence, knowledge is not our norm of assertion. (shrink)

In 'Perceptual Entitlement' (PPR 2003), Tyler Burge argues that on his teleological reliabilist account of perceptual warrant, warrant will persist in non-normal conditions, even radical skeptical scenarios like demon worlds. This paper explains why Burge's explanation falls short. But if we distinguish two grades of warrant, we can explain, in proper functionalist, teleological reliabilist terms, why warrant should persist in demon worlds. A normally functioning belief-forming process confers warrant in all worlds, provided it is reliable in normal conditions when functioning (...) normally. The first grade requires normal functioning. The second grade also requires being situated in normal conditions. (shrink)

Alvin Goldman’s paper “What Is Justified Belief" and his book Epistemology and Cognition pioneered reliabilist theories of epistemic justifiedness. In light of counterexamples to necessity and counterexamples to sufficiency, Goldman has offered a number of refinements and modifications. This paper focuses on those refinements that relativize the justification conferring force of a belief-forming process to its reliably producing a high ratio of true beliefs over falsehoods in special circumstances: reliability in the actual world, in normal worlds, and in nonmanipulated environments. (...) This paper argues that Goldman’s refinements fall short and suggests instead the relativization to reliability in normal circumstances. Normal circumstances are those where the belief-forming process acquired the etiological function of reliably inducing true beliefs. This theory invites the Swampman objection. Two lines of response are pursued. (shrink)

This paper argues for the general proper functionalist view that epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Such a process is reliable in normal conditions when functioning normally. This paper applies this view to so-called testimony-based beliefs. It argues that when a hearer forms a comprehension-based belief that P (a belief based on taking another to have asserted that P) through the exercise of a (...) reliable competence to comprehend and filter assertive speech acts, then the hearer's belief is prima facie warranted. The paper discusses the psychology of comprehension, the function of assertion, and the evolution of filtering mechanisms, especially coherence checking. (shrink)

Jennifer Lackey ('Testimonial Knowledge and Transmission' The Philosophical Quarterly 1999) and Peter Graham ('Conveying Information, Synthese 2000, 'Transferring Knowledge' Nous 2000) offered counterexamples to show that a hearer can acquire knowledge that P from a speaker who asserts that P, but the speaker does not know that P. These examples suggest testimony can generate knowledge. The showpiece of Lackey's examples is the Schoolteacher case. This paper shows that Lackey's case does not undermine the orthodox view that testimony cannot generate (...) knowledge. This paper explains why Lackey's arguments to the contrary are ineffective for they misunderstand the intuitive rationale for the view that testimony cannot generate knowledge. This paper then elaborates on a version of the case from Graham's paper 'Conveying Information' (the Fossil case) that effectively shows that testimony can generate knowledge. This paper then provides a deeper informative explanation for how it is that testimony transfers knowledge, and why there should be cases where testimony generates knowledge. (shrink)

The complexity of human societies of the past few thousand years rivals that of social insect societies. We hypothesize that two sets of social “instincts” underpin and constrain the evolution of complex societies. One set is ancient and shared with other social primate species, and one is derived and unique to our lineage. The latter evolved by the late Pleistocene, and led to the evolution of institutions of intermediate complexity in acephalous societies. The institutions of complex societies often conflict with (...) our social instincts. The complex societies of the past few thousand years can function only because cultural evolution has created effective “work-arounds” to manage such instincts. We describe a series of work-arounds and use the data on the relative effectiveness of WWII armies to test the work-around hypothesis. (shrink)

The use of socially learned information (culture) is central to human adaptations. We investigate the hypothesis that the process of cultural evolution has played an active, leading role in the evolution of genes. Culture normally evolves more rapidly than genes, creating novel environments that expose genes to new selective pressures. Many human genes that have been shown to be under recent or current selection are changing as a result of new environments created by cultural innovations. Some changed in response to (...) the development of agricultural subsistence systems in the Early and Middle Holocene. Alleles coding for adaptations to diets rich in plant starch (e.g., amylase copy number) and to epidemic diseases evolved as human populations expanded (e.g., sickle cell and G6PD defi- ciency alleles that provide protection against malaria). Large-scale scans using patterns of linkage disequilibrium to detect recent selection suggest that many more genes evolved in response to agriculture. Genetic change in response to the novel social environment of contemporary modern societies is also likely to be occurring. The functional effects of most of the alleles under selection during the last 10,000 years are currently unknown. Also unknown is the role of paleoenvironmental change in regulating the tempo of hominin evolution. Although the full extent of culture-driven gene-culture coevolution is thus far unknown for the deeper history of the human lineage, theory and some evidence suggest that such effects were profound. Genomic methods promise to have a major impact on our understanding of gene-culture coevolution over the span of hominin evolutionary history. (shrink)

Our folk epistemology says that if someone knows that P and tells you that P, then, given the absence of defeaters, if you believe what they tell you, you will come to know that P as well. A speaker's knowledge that P is then, for the most part, enough for a hearer to come to know that P. But there are counterexamples to this principle: testimonial knowledge does not always transfer from the speaker to the hearer. Why should that be (...) so? Because testimonial knowledge arises through the flow of information--from conclusive grounds--from the speaker through the speaker's assertion to the hearer's state of comprehension as of the speaker's assertion. A speaker's belief can be based on conclusive grounds, but the speaker's assertion may fail to provide conclusive grounds to the hearer. Then the hearer won't acquire knowledge, even from a knowledgeable speaker. Knowledge from testimony then works more like knowledge through perception. But wait, you say, that can't be so because testimony involves free will but perception does not. The essay ends with a broadly Hume inspired reply to this objection. (shrink)

Epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Evolution by natural selection is the most familiar source of etiological functions. . What then of learning? What then of Swampman? Though functions require history, natural selection is not the only source. Self-repair and trial-and-error learning are both sources. Warrant requires history, but not necessarily that much.

Everettian accounts of quantum mechanics entail that people branch; every possible result of a measurement actually occurs, and I have one successor for each result. Is there room for probability in such an account? The prima facie answer is no; there are no ontic chances here, and no ignorance about what will happen. But since any adequate quantum mechanical theory must make probabilistic predictions, much recent philosophical labor has gone into trying to construct an account of probability for branching selves. (...) One popular strategy involves arguing that branching selves introduce a new kind of subjective uncertainty. I argue here that the variants of this strategy in the literature all fail, either because the uncertainty is spurious, or because it is in the wrong place to yield probabilistic predictions. I conclude that uncertainty cannot be the ground for probability in Everettian quantum mechanics. (shrink)
