A series of recent studies on extant coelacanths has emphasised the slow rate of molecular and morphological evolution in these species. These studies were based on the assumption that a coelacanth is a ‘living fossil’ that has shown little morphological change since the Devonian, and they proposed a causal link between low molecular evolutionary rate and morphological stasis. Here, we have examined the available molecular and morphological data and show that: (i) low intra-specific molecular diversity does not imply low mutation (...) rate, (ii) studies not showing low substitution rates in coelacanth are often neglected, (iii) the morphological stability of coelacanths is not supported by paleontological evidence. We recall that intra-species levels of molecular diversity, inter-species genome divergence rates and morphological divergence rates are under different constraints and they are not necessarily correlated. Finally, we emphasise that concepts such as ‘living fossil’, ‘basal lineage’, or ‘primitive extant species’ do not make sense from a tree-thinking perspective.Editor's suggested further reading in BioEssays Tree thinking for all biology: the problem with reading phylogenies as ladders of progress Abstract.

Confirmation in evolutionary biology depends on what biologists take to be the genuine rivals. Investigating what constrains the scope of biological possibility provides part of the story: explaining how possible helps determine what counts as a genuine rival and thus informs confirmation. To clarify the criteria for genuine rivalry I distinguish between global and local constraints on biological possibility, and offer an account of how-possibly explanation. To sharpen the connection between confirmation and explaining how possible I discuss the view that (...) formal inquiry can provide a kind of confirmation-theoretic support for evolutionary models, and offer an example of how-possibly explanation interacting with testing practice.

Is childhood valuable? And is childhood as, less, or more, valuable than adulthood? In this article I first delineate several different questions that we might be asking when we think about the ‘value of childhood’, and I explore some difficulties of doing so. I then focus on the question of whether childhood is good for the person who experiences it. I argue for two key claims. First, if childhood wellbeing is measured by the same standards as adulthood, then children are (...) worse off than adults. Second, if childhood and adulthood wellbeing are measured by different standards, then we cannot compare them, and children are neither better off nor worse off than adults. This has some counter-intuitive implications, such as that we do not harm persons by depriving them of a childhood, nor by keeping them as children for elongated periods. (shrink)

We discuss the scientific task of historical reconstruction and the problem of epistemic access. We argue that strong epistemic support for historical claims consists in the consilience of multiple independent lines of evidence, and analyze the impact hypothesis for the End-Cretaceous mass extinction to illustrate the accrual of epistemic support. Although there are elements of the impact hypothesis that enjoy strong epistemic support, the general conditions for this are strict, and help to clarify the difficulties associated with reconstructing the deep (...) past.

Evolutionary biology, indeed any science that attempts to reconstruct prehistory, faces practical limitations on available data. These limitations create the problem of contrast failure: specific observations may fail to discriminate between rival evolutionary hypotheses. Assessing the risk of contrast failure provides a way to evaluate testing protocols in evolutionary science. Here I will argue that part of the methodological critique in the Spandrels paper involves diagnosing contrast failure problems. I then distinguish the problem of contrast failure from the more familiar (...) philosophical problem of underdetermination, and demonstrate how contrast failure arises in scientific practice with an investigation into Lewontin and White’s estimation of an adaptive landscape.

This paper reviews the largely psychological literature surrounding apparent failures of human rationality (sometimes referred to as 'the Rationality Wars') and locates it with respect to concepts and issues within more traditional epistemological inquiry. The goal is to bridge the gap between these two large and typically disconnected literatures – concerning rationality and the psychology of human reasoning, on the one hand, and epistemological theories of justified or rational belief, on the other – and to do so in such as (...) way as to expose interesting points of contact and convergence between them.

Can selection explain why individuals have the traits they do? This question has generated significant controversy. I will argue that the debate encompasses two separable aspects, to detrimental effect: (1) the role of selection in explaining the origin and evolution of biological traits and (2) the implications this may have for explaining why individuals have the traits they do. (1) can be settled on the basis of evolutionary theory while (2) requires additional, extra-scientific assumptions. By making a distinction between traits (...) affected by a single factor and traits affected by multiple factors I show that selection can, under certain conditions, help explain the origin of traits. Resolving the first aspect enables us to critically assess the various incompatible and independent philosophical commitments made within the second aspect of the debate. (shrink)

Does science successfully uncover the deep structure of the natural world? Or are the depths forever beyond our epistemic grasp? Since the decline of logical positivism and logical empiricism, scientific realism has become the consensus view: of course our scientific theories apprehend the deep structure of the world. What else could explain the remarkable success of science? This is the explanationist defense of scientific realism, the “ultimate argument.” Kyle Stanford starts here and, using the history of theorizing about biological inheritance (...) as his case study, constructs a convincing argument against the realist consensus in his thought provoking book, Exceeding Our Grasp.1 Here I will review the core of Stanford’s new argument for instrumentalism (§ 1) and discuss his considered view of theoretical science (§ 2).

The concept of media accountability is widely used but remains inadequately defined in the literature and often is restricted to a 1-dimensional interpretation. This study explores perceptions of accountability as manifestations of claims to responsibility, based on philosophical conceptions of the 2 terms, and suggests media accountability be more broadly understood as a dynamic of interaction between a given medium and the value sets of individuals or groups receiving media messages. The shape-shifting nature of the concept contributes to the volatility (...) of debate surrounding conflicting notions of press freedom and responsibility. (shrink)

Questions about dirty hands have often focused on legitimate, secure leaders deciding whether to violate important deontological principles or the rules of interpersonal morality. The purpose of this paper is to show that revolutionaries have dirty hands; revolutionaries do wrong by engaging in unilateral usurpation of the existing system with the hope that latter benefits will justify their actions. Yet, once the revolution securely generates improvements for the common good, the initial usurpation becomes increasingly irrelevant to judgments of the new (...) government’s legitimacy. The paper argues that only retroactive justification—where later success forces opponents and advocates to reinterpret the wrongness of the initial action—can fully capture the complex moral dynamics of revolutions.

Eliminative reasoning seems to play an important role in the sciences, but should it be part of our best theory of science? Statistical evidence, prevalent across the sciences, causes problems for eliminative inference, supporting the view that probabilistic theories of confirmation provide a better framework for reasoning about evidence. Here I argue that deductive elimination has an important inferential role to play in science, one that is compatible with probabilistic approaches to evidence. Eliminative inferences help frame testing problems, an essential (...) step that determines the context for evaluating statistical evidence. I illustrate this process with examples from molecular evolutionary biology. (shrink)

We investigate how changes to the payoffs of cooperative behavior affect the evolutionary dynamics. Paradoxically, the larger the benefits of cooperation, the less likely it is to evolve. This holds true even in cases where cooperation is strictly dominant. Increasing the benefits from prosocial behavior has two effects: first, in some circumstances it promotes the evolution of spite; and second, it can decrease the strength of selection leading to nearly neutral evolution of strategies. In light of these results we must (...) reevaluate standard philosophical perspectives on the evolution of cooperation and morality. (shrink)

Recent studies in the evolution of cooperation have shifted focus from altruistic to mutualistic cooperation. This change in focus is purported to reveal new explanations for the evolution of prosocial behavior. We argue that the common classification scheme for social behavior used to distinguish between altruistic and mutualistic cooperation is flawed because it fails to take into account dynamically relevant game-theoretic features. This leads some arguments about the evolution of cooperation to conflate dynamical scenarios that differ regarding the basic conditions (...) on the emergence and maintenance of cooperation. We use the tools of evolutionary game theory to increase the resolution of the classification scheme and analyze what evolutionary inferences classifying social behavior can license. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Proceedings of the ALSC (1995 Convention)Patrick HenryGiven the oppressively politicized character of academic literary studies today, it took courage and conviction to found a new literary society in 1994. The Association of Literary Scholars and Critics is dedicated to the study of literature as a source of pleasure and insight. This would be banal were it not for the way in which culture wars, identity politics, and race (...) and gender issues have come to dominate university literature departments. More than merely a handful of scholars wish to reverse this trend: in less than two years, the ALSC has grown to 1800 members and its first conference, held in Minneapolis, September 22–24, 1995, was a notable success.Because we favor a true pluralism, and like many others are tired of the predictable posturing that permeates so much literary scholarship today, we invited the ALSC to publish its first conference proceedings in our pages. The meeting offered much variety, with classicists and modernists, poets, fiction writers, and critics trading ideas on literature and aesthetics. Despite worries by its detractors that the ALSC represents reaction or blind traditionalism, there was a refreshing openness to the proceedings, with lucid examples of critical reading and topics from metaphor in Dickens and Auden’s Alcaic stanza in “In memory of Sigmund Freud,” to the Islamic influence on Dante’s Commedia—a connection that belies the charge that the Western canon is inevitably Eurocentric. If the ALSC can revive a sense of wonder before the greatest works of literary art and provide an alternative to the complacency and pretentiousness of contemporary theory, it deserves support from us all.For twenty years it has said on our inside back cover that Philosophy and Literature “owes allegiance to no particular school or style of criticism or philosophy.” Our only loyalty is to literature and philosophy; they constitute our field of interest. It has never been our aim to adopt the correct ideology. We remain skeptical of ideological commitments and will continue to publish exciting jargon-free articles representative of the entire spectrum of approaches to literature and philosophy.Copyright © 1996 The Johns Hopkins University Press...

When incorporating the environment into mental processing (cf., cognitive offloading), one creates novel cognitive strategies that have the potential to improve task performance. Improved performance can, for example, mean faster problem solving, more accurate solutions, or even higher grades at university.1 Although cognitive offloading has frequently been associated with improved performance, it is yet unclear how flexible problem solvers are at matching their offloading habits with their current performance goals (can people improve goal‐related instead of generic performance, e.g., when being (...) in a hurry and aiming for a “quick and dirty” solution?). Here, we asked participants to solve a cognitive task, provided them with different goals—maximizing speed (SPD) or accuracy (ACC), respectively—and measured how frequently (Experiment 1) and how proficiently (Experiment 2) they made use of a novel external resource to support their cognitive processing. Experiment 1 showed that offloading behavior varied with goals: Participants offloaded less in the SPD than in the ACC condition. Experiment 2 showed that this differential offloading behavior was associated with high goal‐related performance: fast answers in the SPD, accurate answers in the ACC condition. Simultaneously, goal‐unrelated performance was sacrificed: inaccurate answers in the SPD, slow answers in the ACC condition. The findings support the notion of humans as canny offloaders who are able to successfully incorporate their environment in pursuit of their current cognitive goals. Future efforts should be focused on the finding's generalizability, for example, to settings without feedback or with high mental workload. (shrink)

A common anti-egalitarian argument is that equality is motivated by envy, or the desire to placate envy. In order to avoid this charge, John Rawls explicitly banishes envy from his original position. This article argues that this is an inconsistent and untenable position for Rawls, as he treats envy as if it were a fact of human psychology and believes that principles of justice should be based on such facts. Therefore envy should be known about in the original position. The (...) consequences for Rawlsian theory—both substantive and methodological—are discussed. (shrink)

This article explores the surprisingly decisive role that Kant’s “incongruity theory” of laughter plays in his aesthetic and broader critical philosophy. First, laughter constitutes a highly specific form of aesthetic judgment in Kant. Laughter involves a discordant relation between the cognitive faculties characteristic of the sublime, but this relation obtains between the understanding and the imagination, the two faculties at play in judgments of taste on the beautiful. Second, laughter is the transcendental condition of possibility for both the beautiful and (...) the sublime. While most commentators dismiss laughter as an afterthought of Kant’s aesthetics, laughter in fact constitutes the most basic aesthetic judgment in Kant. Third, an account of aesthetic judgment that begins with laughter transforms how we understand Kant’s argument that judgment unites nature and freedom. Namely, it reveals how an empirical world at odds with the subject’s purposes can nevertheless advance the subject’s rational vocation to think and act beyond the empirical. I conclude by arguing that Kantian critical philosophy is itself a philosophy of laughter. (shrink)

Our scientific theories, like our cognitive structures in general, consist of propositions linked by evidential, explanatory, probabilistic, and logical connections. Those theoretical webs ‘impinge on the world at their edges,’ subject to a continuing barrage of incoming evidence. Our credences in the various elements of those structures change in response to that continuing barrage of evidence, as do the perceived connections between them. Here we model scientific theories as Bayesian nets, with credences at nodes and conditional links between them modelled (...) as conditional probabilities. We update those networks, in terms of both credences at nodes and conditional probabilities at links, through a temporal barrage of random incoming evidence. Robust patterns of punctuated equilibrium, suggestive of ‘normal science’ alternating with ‘paradigm shifts,’ emerge prominently in that change dynamics. The suggestion is that at least some of the phenomena at the core of the Kuhnian tradition are predictable in the typical dynamics of scientific theory change captured as Bayesian nets under even a random evidence barrage.

This lecture is cpncerned with the expected-utility or Bayesian model of rationality, with particular attention both to the strengths and limitations of the model. The alternative market and legal models of rationality are examined and rejected as less satisfactory than the expected-utility model. The role of intuitive judgement in the context of actual decision making is stressed. The fundamental place of intuitive judgement in science, especially in the performance of experiments and the analysis and presentation of results is analyzed. Errors (...) of measurement naturally arise in application of the expected-utility model, but there is a long history of theory and practice for dealing with such errors. The existence of such errors constitutes a limitation, not a prohibition, on the use of expected-utility theory as a fundamental framework for rational behaviour. (shrink)

One feature of the individuals Nietzsche considers paradigms of greatness is that they are, in some capacity, rare —an exception to the majority.1 It would be difficult to overstate the frequency of this association in the texts. From as early as UM, Nietzsche repeatedly contrasts the “rarest and most valuable exemplars” with the pejorative “herd [Heerde]”, the “common [gemein]”, the “mediocre [mittelmässig]”, and the “rabble [Pöbel]”.2 This contrast becomes more explicit in Nietzsche’s mature period, where, for example, he writes plainly (...) that “what can be common has ever but little...

Research on collaborative professionalism may be enriched by inquiries into the lived experiences of teachers. The question of what collaboration is like for teachers has not been taken up widely in the literature. The meaning of collaboration as a coming together of individuals who share, design, and co-create for purposes that are aligned with generative possibilities of producing something new, of understanding something in a novel way, and to combine perspectives, personalities, experiences and expertise, represents a new area for research. (...) This paper presents a phenomenological analysis of teachers’ lived experiences of collaboration. To ask these questions requires an orientation to the lived experience of teacher collaboration. For the purposes of this paper, two themes – collaboration and a creative imaginary, and collaboration and relationality – are described as unique structures of human experience. This research supports the conclusion that research in the field of collaborative professionalism and teacher collaboration may be significantly deepened by inquiries into concrete lived experiences of teacher collaboration.

ABSTRACT Nietzsche's investigation into the origins of morality bears some striking similarities to contemporary investigations into human evolution. Here I investigate these similarities, using a comparison between Nietzsche's GM and Gould and Lewontin's influential “Spandrels” essay as a departure point. I argue that Nietzsche defends a proto-evolutionary psychology about morality, where the inheritance of enduring biological drives conflicts with our culturally evolved moral system. While Nietzsche's claims about the evolution of morality fit well within a Darwinian framework of natural selection, (...) his claims about our underlying biology do not. Those claims cohere better with the non-Darwinian views found in nineteenth-century German biology and embryology. (shrink)

Schopenhauer is one of the few philosophers in the history of Western ethics to dedicate sustained critical attention to the nature, extent, and phenomenology of malice. Yet while other aspects of Schopenhauer's moral psychology have received significant attention, his nuanced account of malice is under-explored. This paper attempts to remedy this oversight. It argues that Schopenhauer defends a unified and hierarchical account of moral vice in which malice is a sui generis motive, the pinnacle of immorality, and far more pervasive (...) in the human psyche than typically recognized. Moreover, it is argued that part of the significance of Schopenhauer’s account lies in how his idiosyncratic conceptual framework allows him to philosophically capture many widespread beliefs about malicious persons — particularly the view that malice is best explained in terms of the agents own inner-suffering. Nevertheless, Schopenhauer’s views about malice raise a number of interpretive puzzles, which the paper subsequently aims to elucidate and solve. (shrink)

This article looks at some major goals that have been set for sanctions and evaluates how effective sanctions have been at reaching those goals. It also examines the costs of sanctions, i.e., the impact on civilians and on international support for sanctions.

Any behavior belongs to innumerable overlapping types. Any adequate theory of emergence and retention of behavior, whether psychological or biological, must give us not only a general mechanism – reinforcement or selection, for example – but a reason why that mechanism applies to a particular behavior in terms of one of its types rather than others. Why is it as this type that the behavior is reinforced or selected?

In “Kant and Degrees of Responsibility,” Joe Saunders claims that “Degrees of responsibility are important for both our moral and legal practices” and argues that “transcendental idealism precludes Kant from vindicating these judgments [about degrees of responsibility]” ; thus, we have reasons to reject Kant’s transcendental idealism. In this paper, I show how Kant’s transcendental idealism can accommodate and provide a metaphysical account for degrees of responsibility. Whether this “vindicates” such judgments depends upon how much one expects a philosophical account (...) to do; I defend modesty there while admitting a reasonable desire for reflection on how we can and should make such judgments. Finally, I raise the question of just how important judgments of moral responsibility are. Rather than looking to metaphysics to figure out how to vindicate judgments about degrees of responsibility, I suggest we look to the practical purposes such judgments serve. (shrink)

Despite any shortcomings of Kant's transcendental philosophy, the spirit of Kant's approach is correct. In particular, Kant is correct to believe an accurate account of the types of “access” humans possess to internal and empirical content should form the groundwork for epistemic and ethical investigation and epistemic and ethical investigations cannot successfully circumvent this groundwork. In this context, the term “access” concerns the mental processes that render internal and external experience possible. In supporting the above claims, this article outlines and (...) defends what can be considered a weak version of Kant's transcendental approach. This weaker approach does not require the achievement of synthetic a priori judgments, which permit deductive conclusions concerning possible experience. (shrink)

We are in Florence and Ferrara, between 1300 and 1600 A.D. At the beginning of this period the subjects of petty Italian potentates dream of a universal Empire and Church: a universal confined to the Latin world. Over the next three centuries this dream gradually fades; the idea of a universal Church is largely replaced by a discourse addressed to the individual conscience while in the political world sovereignty becomes synonymous with local power. The universal is progressively dissolved within a (...) multiplicity of separate regimes, each rooted in its own territory; in other words, individual societies achieve spiritual legitimation by a transfer of sovereignty. Thus linked with the absolute, territorial sovereignty, rehabilitating the idea of the local, becomes the foundation of the many-sided flowering of the Renaissance. A reading of the poets is helpful in grasping the full complexity of this historical transformation. How were Dante, Petrarch and those poets who imitated the poets of Antiquity, the so-called Petrarchists, understood? This study will focus on the way in which the texts were created. By comparing them we will try to elucidate what makes for the importance and urgency of these poems. (shrink)
