One foundational question in contemporarybiology is how to `rejoin evolution anddevelopment. The emerging research program(evolutionary developmental biology or`evo-devo) requires a meshing of disciplines,concepts, and explanations that have beendeveloped largely in independence over the pastcentury. In the attempt to comprehend thepresent separation between evolution anddevelopment much attention has been paid to thesplit between genetics and embryology in theearly part of the 20th century with itscodification in the exclusion of embryologyfrom the Modern Synthesis. This encourages acharacterization of evolutionary developmentalbiology as the marriage (...) of evolutionary theoryand embryology via developmental genetics. Butthere remains a largely untold story about thesignificance of morphology and comparativeanatomy (also minimized in the ModernSynthesis). Functional and evolutionarymorphology are critical for understanding thedevelopment of a concept central toevolutionary developmental biology,evolutionary innovation. Highlighting thediscipline of morphology and the concepts ofinnovation and novelty provides an alternativeway of conceptualizing the `evo and the `devoto be synthesized. (shrink)

Nobody wants unnatural kinds. Just as we prefer all natural ingredients in our food, so also we prefer natural kinds in our ontology and epistemology. Philosophers contrast natural with merely “conventional” kinds, and scientists advocate for natural rather than artificial classification systems. A central plank of the desired naturalness is “mind independence”—the property of existing independent of human interests and desires. Natural kinds are discovered, not made. They reflect the structure of the world (“nature’s joints”) and for this reason (...) justify the practice of inductive inference. Conventional kinds, by contrast, are dependent on human classificatory activities. They are created with an end in view and therefore lack “a real existence in nature” (J. S. Mill, A System of Logic, Ratiocinative and Inductive [London: Longmans, 1843], 1:165). Since their existence is dependent on human activities, nominal kinds need not track nature’s joints. Because scientists are interested in groupings that really exist in nature—not those fabricated for human purposes—their classificatory practices aim to achieve natural-kind classifications. Achieving these classifications is crucial to the success of science. (shrink)

Previous research about love, in the social-psychological literature, has focused on the antecedents, or causes, of love. Moreover, within the field of Personal Relationships, love is often regarded as implicitly present, and thus, is not treated directly. Here, we address the possibility of a reversal of this perspective, where love is no longer treated as a dependent variable but as an independent variable. We show that this change is necessary to promote the status (...) of love to that of a reliable object of scientific enquiry. We discuss the differences between scientific and naïve conceptions of love, and the necessity of distinguishingbetween an alleged reality of love and the consequences of the mere idea of love.

Night eating syndrome is currently classified as an Other Specified Feeding or Eating Disorder under the Diagnostic Statistical Manual−5. This systematic review aims to consolidate the studies that describe the sociodemographic, clinical and psychological features of NES in a population of patients with eating disorders, obesity, or those undergoing bariatric surgery, and were published after the publication of the DSM-5. A further aim was to compare, where possible, NES with BED on the aforementioned variables. Lastly, we aimed to appraise the (...) quality of the studies being included in the review. We conducted a systematic search on three databases which resulted in the selection of 22 studies for the review. We included the articles that studied patients with NES and their sociodemographic, clinical and psychological features in a clinical population, through a quantitative study design. Articles were excluded if the NES patients included in the study had a comorbid psychological disorder, and/or the sample was collected from a university/non-clinical population, and/or the study design was qualitative, and/or NES features were compared with any other disorder, except BED. Our study found that no conclusions about the link between any sociodemographic feature and an NES diagnosis could be made. Further, NES patients presented with elevated ED pathology and higher occurrence of depressive symptoms than controls. Contrary to the literature suggesting that NES and Binge Eating Disorder patients often report overlapping features, questioning the validity of NES as an ED diagnosis, we found that BED can be differentiated from NES by the higher occurrence of emotional eating, body related concerns and abnormal eating episodes. The review also suggested an overlap between NES and Sleep-Related Eating Disorder. We recommend that it is essential to study NES as an independent disorder to further develop its diagnostic criteria and treatment options, thereby, increasing the quality of life of the patients suffering from this syndrome.

This paper analyses the evolutionary characteristics of the interprovincial population mobility network structure in China and explores the roles of provinces from 2010 to 2015. By constructing the interprovincial population mobility network, we examine the provinces’ functions during periods of population mobility through population mobility diversity, population mobility, and population mobility intermediation. The results show that the coverage and tightness of the interprovincial population mobility network were influenced by national economic development, increasing steadily from 2010 to 2014 and then suddenly (...) falling in 2015. The regions that played essential roles in the province’s mobility diversity and intermediation showed a dispersion trend. In contrast, areas that played a vital role in the inflows or outflows were relatively concentrated and stable. Additionally, this work further explores how economic factors, e.g., GDP, residents’ consumption levels, total population, unemployment rate, and consumer price index, are used as independent variables to analyse the provinces’ roles in the interprovincial population mobility network. The analysis shows that the inflow or outflow volumes are easily affected by the five indices. These five indices are significantly related to network role indicators to different extents. (shrink)

Canonical utility theory may have adopted its selfishness postulate because it lacked theoretical rationales for two major kinds of incentive: empathic utility and self-signaling. Empathy – using vicarious experiences to occasion your emotions – gives these experiences market value as a means of avoiding the staleness of self-generated emotion. Self-signaling is inevitable in anyone trying to overcome a perceived character flaw. Hyperbolic discounting of future reward supplies incentive mechanisms for both empathic utility and self-signaling. Neither can be effectively suppressed for (...) an experimental game. (shrink)

Aims and hypothesesIn an environment of absolute silence, researchers have found many of their participants to perceive phantom sounds. With this between-subject experiment, we aimed to elaborate on these research findings, and specifically investigated whether–in line with the fear-avoidance model of tinnitus perception and reactivity–fear or level of perceived threat influences the incidence and perceptual qualities of phantom sound percepts in an anechoic room. We investigated the potential role of individual differences in anxiety, negative affect, noise sensitivity and subclinical hearing (...) loss. We hypothesized that participants who experience a higher level of threat would direct their attention more to the auditory system, leading to the perception of tinnitus-like sounds, which would otherwise be subaudible, and that under conditions of increased threat, narrowing of attention would lead to perceptual distortions.MethodsIn total, N = 78 normal-hearing volunteers participated in this study. In general, the study sample consisted of young, mostly female, university students. Their hearing was evaluated using gold-standard pure tone audiometry and a speech-in-noise self-test, which is a sensitive screening test to identify subclinical hearing loss. Prior to a four-minute stay in an anechoic room, we randomized participants block design-wise in a threat and no-threat condition. Participants in the threat condition were deceived about their hearing and were led to believe that staying in the room would potentially harm their hearing temporarily. Participants were asked whether they perceived sounds during their stay in the room and rated the perceptual qualities of sound percepts. They were also asked to fill-out standardized questionnaires measuring anxiety, affect and noise sensitivity. The internal consistency of the questionnaires used was verified in our study sample and ranged between α = 0.61 and α = 0.90.ResultsIn line with incidence rates reported in the literature, 74% of our participants reported having heard tinnitus-like sounds in the anechoic room. Speech-in-noise identification ability was comparable for both groups of participants. The experimental manipulation of threat was proven to be effective, as indicated by significantly higher scores on a Threat Manipulation Checklist among participants in the threat condition as compared to those in the no-threat condition. Nevertheless, participants in the threat condition were as likely to report tinnitus percepts as participants in the no-threat condition, and tinnitus percepts were not rated as being louder or more unpleasant as a function of level of threat. For participants who did experience tinnitus percepts, a higher level of threat was associated with a higher degree of experienced unpleasantness. These associations were absent in those who did not experience tinnitus. Higher negative affect was only slightly associated with higher ratings of tinnitus unpleasantness.ConclusionWhereas our threat manipulation was successful in elevating the level of fear, it did not contribute to a higher percentage of participants perceiving tinnitus-like sounds in the threat condition. However, higher levels of perceived threat were related to a higher degree of perceived tinnitus unpleasantness. The findings of our study are drawn from a rather homogenous participant pool in terms of age, gender, and educational background, challenging conclusions that are applicable for the general population. Participants generally obtained normophoric scores on independent variables of interest: they were low anxious, low noise-sensitive, and there was little evidence for the presence of subclinical hearing loss. Possibly, there was insufficient variation in scores to find effects. (shrink)

At first glance, love seems to be a psychological state for which there are normative reasons: a state that, if all goes well, is an appropriate or fitting response to something independent of itself. Love for one’s parent, child, or friend is fitting, one wants to say, if anything is. On reflection, however, it is elusive what reasons for love might be. It is natural to assume that they would be nonrelational features of the person one (...) loves, something about her in her own right. According to the “quality theory,” for example, reasons for love are the beloved’s personal attributes, such as her wit and beauty. In J. David Velleman’s provocative and ingeniously argued proposal, the reason for love is the beloved’s bare Kantian personhood, her capacity for rational choice and valuation. But no such nonrelational feature works. To appreciate just one difficulty, observe that whatever nonrelational feature one selects as the reason for love will be one that another person could, or actually does, possess. The claim that nonrelational features are reasons for love implies, absurdly, that insofar as one’s love for Jane is responsive to its reasons, it will accept any relevantly similar person as a replacement.

ABSTRACT In Why Worry about Future Generations?, Samuel Scheffler argues that we typically love humanity, and that this attachment gives us reasons to care about future generations. The paper explores this idea with an eye to understanding better the sense in which humanity is an object of attachment. The paper argues that the humanity we love should be understood in an enriched rather than a reductively biological sense, as a species that has historically sustained a complex set of (...) cultural and personal meanings. Caring about this object will lead us to be concerned about future generations. But these reasons of love should not be understood as reasons to be concerned directly about the fate of individual future people. The paper concludes with some reflections about the attachment-independent value of humanity in the enriched sense, distinguishing between relational and non-relational interpretations of this independent value.

Using the context of controversies surrounding evolutionary developmental biology (EvoDevo) and the possibility of an Extended Evolutionary Synthesis, I provide an account of theory structure as idealized theory presentations that are always incomplete (partial) and shaped by their conceptual content (material rather than formal organization). These two characteristics are salient because the goals that organize and regulate scientific practice, including the activity of using a theory, are heterogeneous. This means that the same theory can be structured differently, in part because (...) theory presentations (as idealizations) intentionally depart from different features known to be present in a theory. Since there are diverse and potentially incompatible theory structures derived from heterogeneous goals found in scientific practices, a question arises about the absence of a unifying theory structure in the background. The notion of a “theory façade” offers a fruitful perspective on this potentially unsettling result. (shrink)

It is a common complaint that antireductionist arguments are primarily negative. Here I describe an alternative nonreductionist epistemology based on considerations taken from multidisciplinary research in biology. The core of this framework consists in seeing investigation as coordinated around sets of problems (problem agendas) that have associated criteria of explanatory adequacy. These ideas are developed in a case study, the explanation of evolutionary innovations and novelties, which demonstrates the applicability and fruitfulness of this nonreductionist epistemological perspective. This account also bears (...) on questions of conceptual change and theory structure in philosophy of science. †To contact the author, please write to: Department of Philosophy, University of Minnesota, 831 Heller Hall, 271 19th Ave. S., Minneapolis, MN 55455; e‐mail: [email protected].

“Functional homology” appears regularly in different areas of biological research and yet it is apparently a contradiction in terms—homology concerns identity of structure regardless of form and function. I argue that despite this conceptual tension there is a legitimate conception of ‘homology of function’, which can be recovered by utilizing a distinction from pre-Darwinian physiology (use versus activity) to identify an appropriate meaning of ‘function’. This account is directly applicable to molecular developmental biology and shares a connection to the theme (...) of hierarchy in homology. I situate ‘homology of function’ within existing definitions and criteria for structural assessments of homology, and introduce a criterion of ‘organization’ for judging function homologues, which focuses on hierarchically interconnected interdependencies (similar to relative position and connection for skeletal elements in structural homology). This analysis of biological concepts has at least three broad philosophical consequences: (1) it provides the grounds for the study of behavior and psychological categories as homologues; (2) it demonstrates that philosophers who take selected effect function as primary effectively ignore large portions of comparative, structural, and experimental research, thereby misconstruing biological reasoning and knowledge; and, (3) it underwrites causal generalizations, which illuminates inferences made from model organisms in experimental biology.

This chapter describes the theoretical implications of Extended Synthesis and addresses the methodological options available for determining aspects of theoretical structure. It uses a “bottom-up” approach focused on evolutionary theory in particular, as opposed to a “top-down” strategy that attempts to characterize the structure of all scientific theories.

It suggests that the philosophical analysis offered in the chapter regarding the structure of evolutionary theory (...) assists attempts to recover coherence through the vehicle of an Extended Synthesis.

Many philosophers of biology have embraced a version of pluralism in response to the failure of theory reduction but overlook how concepts, methods, and explanatory resources are in fact coordinated, such as in interdisciplinary research where the aim is to integrate different strands into an articulated whole. This is observable for the origin of evolutionary novelty—a complex problem that requires a synthesis of intellectual resources from different fields to arrive at robust answers to multiple allied questions. It is an apt (...) locus for exploring new dimensions of explanatory integration because it necessitates coordination among historical and experimental disciplines . These coordination issues are widespread for the origin of novel morphologies observed in the Cambrian Explosion. Despite an explicit commitment to an integrated, interdisciplinary explanation, some potential disciplinary contributors are excluded. Notable among these exclusions is the physics of ontogeny. We argue that two different dimensions of integration—data and standards—have been insufficiently distinguished. This distinction accounts for why physics-based explanatory contributions to the origin of novelty have been resisted: they do not integrate certain types of data and differ in how they conceptualize the standard of uniformitarianism in historical, causal explanations. Our analysis of these different dimensions of integration contributes to the development of more adequate and integrated explanatory frameworks. (shrink)

Although no one unified anarchist theory exists, educational approaches can be taken to support the full liberation of the self and the construction of an interconnected community that strives to rid itself of eco-sociocultural oppressions. An anarchist pedagogical approach could be one that is rooted in a love/rage unit of analysis occurring along a spectrum of various types of actions and contributions within a community. Anarchism as a violent destruction of the state is a stereotypical view that has perhaps (...) led to its own early demise as a social movement. Anarchism that embraces adaptation through more inclusive forms of resistance, including a reconstruction for the K?12 classroom context, is one that stands a chance in evolving a society toward love, justice, and empowerment. This article explores those possibilities aiming for accessibility while still honoring core anarchist calls for strong, localized democratic participation and decision-making outside of permanent hierarchies.

The goal of this paper is to encourage a reconfiguration of the discussion about typology in biology away from the metaphysics of essentialism and toward the epistemology of classifying natural phenomena for the purposes of empirical inquiry. First, I briefly review arguments concerning ‘typological thinking’, essentialism, species, and natural kinds, highlighting their predominantly metaphysical nature. Second, I use a distinction between the aims, strategies, and tactics of science to suggest how a shift from metaphysics to epistemology might be accomplished. Typological (...) thinking can be understood as a scientific tactic that involves representing natural phenomena using idealizations and approximations, which facilitates explanation, investigation, and theorizing via abstraction and generalization. Third, a variety of typologies from different areas of biology are introduced to emphasize the diversity of this representational reasoning. One particular example is used to examine how there can be epistemological conflict between typology and evolutionary analysis. This demonstrates that alternative strategies of typological thinking arise due to the divergent explanatory goals of researchers working in different disciplines with disparate methodologies. I conclude with several research questions that emerge from an epistemological reconfiguration of typology. (shrink)

Although the role of morphology in evolutionary theory remains a subject of debate, assessing the contributions of morphological investigation to evolutionary developmental biology (Evo-devo) is a more circumscribed issue of direct relevance to ongoing research. Historical studies of morphologically oriented researchers and the formation of the Modern Synthesis in the Anglo-American context identify a recurring theme: the synthetic theory of evolution did not capture multiple levels of biological organization. When this feature is incorporated into a philosophical framework for explaining the (...) origin of evolutionary innovations and novelties (a core domain of inquiry in Evo-devo) two specific roles for morphology can be described: (1) the conceptualization and operational identification of the targets of explanation; and (2) the elucidation of causal interactions at higher levels of organization during ontogeny and through evolutionary time. These roles are critical components of any adequate explanation of innovation and novelty though not exhaustive of the parts played by morphology in evolutionary investigation. They also invite reflection on what counts as an evolutionary cause in contemporary evolutionary biology. (shrink)

Although natural philosophers have long been interested in individuality, it has been of interest to contemporary philosophers of biology because of its role in different aspects of evolutionary biology. These debates include whether species are individuals or classes, what counts as a unit of selection, and how transitions in individuality occur evolutionarily. Philosophical analyses are often conducted in terms of metaphysics (“what is an individual?”), rather than epistemology (“how can and do researchers conceptualize individuals so as to address some of (...) their scientific goals?”). We review several philosophical distinctions in order to shift attention from metaphysics to epistemology. Many controversies involve epistemological differences rather than metaphysical disagreement. This implies that a pluralist stance about individuality in biology is warranted and has metaphysical consequences because the pluralism emerges from the diversity of scientific interests that investigate the complexity of living phenomena.

Günter Wagner’s Homology, Genes, and Evolutionary Innovation collects and synthesizes a vast array of empirical data, theoretical models, and conceptual analysis to set out a progressive research program with a central theoretical commitment: the genetic theory of homology. This research program diverges from standard approaches in evolutionary biology, provides sharpened contours to explanations of the origin of novelty, and expands the conceptual repertoire of evolutionary developmental biology. I concentrate on four aspects of the book in this essay review: the genetic (...) theory of homology and character identity networks; the implications for how we explain evolutionary novelties; the expanded set of concepts surrounding homology, and the epistemological conflicts between Wagner’s viewpoint and functionally-oriented evolutionary biology, as well as differences with other Evo–devo researchers. Together these have ramifications for how we interpret different explanatory approaches to evolutionary phenomena and understand relationships between the usefulness of concepts and the reality they represent.

Every scientist chooses a preferred level of analysis and this choice shapes the research program, even determining what counts as evidence. This contribution revisits Marr's three levels of analysis and evaluates the prospect of making progress at each individual level. After reviewing limitations of theorizing within a level, two strategies for integration across levels are considered. One is top–down in that it attempts to build a bridge from the computational to algorithmic level. Limitations of this approach include insufficient theoretical constraint (...) at the computation level to provide a foundation for integration, and that people are suboptimal for reasons other than capacity limitations. Instead, an inside-out approach is forwarded in which all three levels of analysis are integrated via the algorithmic level. This approach maximally leverages mutual data constraints at all levels. For example, algorithmic models can be used to interpret brain imaging data, and brain imaging data can be used to select among competing models. Examples of this approach to integration are provided. This merging of levels raises questions about the relevance of Marr's tripartite view. (shrink)

Idealization is a reasoning strategy that biologists use to describe, model and explain that purposefully departs from features known to be present in nature. Similar to other strategies of scientific reasoning, idealization combines distinctive strengths alongside of latent weaknesses. The study of ontogeny in model organisms is usually executed by establishing a set of normal stages for embryonic development, which enables researchers in different laboratory contexts to have standardized comparisons of experimental results. Normal stages are a form of idealization because (...) they intentionally ignore known variation in development, including variation associated with phenotypic plasticity (e.g. via strict control of environmental variables). This is a tension between the phenomenon of plasticity and the practice of staging that has consequences for evolutionary developmental investigation because variation is conceptually removed as a part of rendering model organisms experimentally tractable. Two compensatory tactics for mitigating these consequences are discussed: employing a diversity of model organisms and adopting alternative periodizations. (shrink)

A central reason that undergirds the significance of evo-devo is the claim that development was left out of the Modern synthesis. This claim turns out to be quite complicated, both in terms of whether development was genuinely excluded and how to understand the different kinds of embryological research that might have contributed. The present paper reevaluates this central claim by focusing on the practice of model organism choice. Through a survey of examples utilized in the literature of the Modern synthesis, (...) I identify a previously overlooked feature: exclusion of research on marine invertebrates. Understanding the import of this pattern requires interpreting it in terms of two epistemic values operating in biological research: theoretical generality and explanatory completeness. In tandem, these values clarify and enhance the significance of this exclusion. The absence of marine invertebrates implied both a lack of generality in the resulting theory and a lack of completeness with respect to particular evolutionary problems, such as evolvability and the origin of novelty. These problems were salient to embryological researchers aware of the variation and diversity of larval forms in marine invertebrates. In closing, I apply this analysis to model organism choice in evo-devo and discuss its relevance for an extended evolutionary synthesis. (shrink)

Developmental biology is the science of explaining how a variety of interacting processes generate the heterogeneous shapes, size, and structural features of an organism as it develops rom embryo to adult, or more generally throughout its life cycle (Love, 2008b; Minelli, 2011a). Although it is commonplace in philosophy to associate sciences with theories such that the individuation of a science is dependent on a constitutive theory or group of models, it is uncommon to find presentations of developmental biology making (...) reference to a theory or theories of development. For example, in the third edition of Essential Developmental Biology (Slack, 2013), three families of approaches are described (developmental genetics, experimental embryology, and molecular and cell biology), and the appendix contains a catalogue of ‘key molecular components’ (genes, transcription factor, families, inducing factor families, cytoskeleton, cell adhesion molecules, and extracellular matrix components); however, no standard theory or group of models provides a theoretical scaffolding to the book nor is any mentioned.

Alexandre Kojève not infrequently claimed that he was a Stalinist. While many have ignored his claim, this paper takes it seriously and outlines several aspects of Kojève’s thought that allow one to read Kojève as a philosopher of Stalinism, as one who articulates the self-consciousness of Stalinism. These aspects are three: Kojève’s association of finality and freedom with the overcoming of individuality; the attempt to achieve finality and freedom so defined in the universal homogeneous state, and the structure of that (...) state as an essentially juridical administrative system. The question remains, however, whether one can truly overcome individuality while one is still living, the conflict between individual material existence and the overarching state being irresolvable.

Evolutionary developmental biology (or developmental evolution) is in the middle stages of its “development.” Its early ontogeny cannot be traced back to fertilization but pivotal developmental events included Gould’s (1977) treatment of heterochrony, Riedl’s (1978) analysis of “burden”, the Dahlem conference of 1981, a British Society of Developmental Biologists Symposium, as well as books that incorporated developmental genetics into older comparative themes. A major inductive process began with the discovery of widespread phylogenetic conservation in homeobox-containing genes. One interpretation of these (...) early developmental dynamics holds that an increasingly prominent problem agenda (e.g., how do novel structures and functions originate?), inherited from long-standing research programs in comparative embryology, morphology, and paleontology, was handed a powerful set of experimental tools from the lineage of experimental embryology. This allowed for an experimental probing of development and its evolution in an unprecedented fashion. Although the relationship between evolution and development has exhibited a protracted and complex history, we are still in the process of comprehending these early stages of “modern” EvoDevo’s ontogeny.

It is well documented that the application of business models to the higher education sector has precipitated a managerialistic approach to organisational structures ( Preston, 2001 ). Less well documented is the impact of this business ideal on the student-teacher encounter. It is argued that this age-old relation is now being configured (conceptually and organisationally) in terms peculiar to the business sector: as a customer-product relation. It is the applicability and suitability of such a configuration that specifically concerns this contribution. (...) The paper maintains that the move to describe the student-teacher relation in these terms is indeed inappropriately reductive, but not straightforwardly so. The problem arises in that we remain unsure of the contemporary purpose of education. We lack any firm educational ideals that, in themselves, cannot be encompassed by the business paradigm. Indeed, the pedagogical critique of education (broadly, that education is only of use in as much as it is of use to society) extends further than has yet been intimated and prevents one securing any educational ideal that does not immediately succumb to critique. This pedagogical logic is unassailable in any linear way but, when pressed, precipitates an aporetic moment that prevents it from assuming any totalising hold over education. We draw on the work of Emmanuel Levinas and Jacques Derrida to consider whether one might yet imagine an educational 'quasi-ideal' that will enable practitioners and institutions to counter the effects of customerisation.

This article presents a new aesthetic of the improvised jazz solo, an aesthetic grounded in the premise that a solo is an act indivisible from the actor and the context. The solo's context includes the local and large-scale conventions of jazz performance as well as the soloist's other work. The theme on which a solo is based serves not as a “work,” but as part of the solo's stylistic context. Knowledge of this context inheres directly into proper apprehension of the (...) musical surface; it does not constitute a separate plane of appreciation. I begin by examining the improvisational error. This examination supports the position that the solo is an act, not a work. From this position, I detail a new aesthetic of the improvised solo, grounded in the soloist's virtues. In a successful solo, the soloist's actions display a balance of two aesthetic “virtues”: compositional skill and a commitment to the spirit of improvisation. Compositional skill manifests in a solo as coherence. The improvisational spirit manifests as courage, spontaneity, and related qualities. These virtues often come into conflict; each soloist negotiates this conflict differently. (shrink)

With the publication of Martin Heidegger’s Black Notebooks, it has become impossible to avoid Heidegger’s anti-Semitism. There has been the expected controversy with Heideggerians on the defensive and the philosopher’s detractors condemning his work outright. But there has been little serious exploration of the matter aside from several recent works. This article builds on this literature on Heidegger’s anti-Semitism and concludes that an anti-Semitic narrative lies at the heart of Heidegger’s history of the oblivion of Being as nihilism. Moreover, Heidegger (...) adopts the narrative framework set up by Friedrich Nietzsche in On the Genealogy of Morality. In the end, we assert that Heidegger advocates a kind of war against Judaism that seeks to eradicate the Jewish influence in the western tradition. Heidegger’s ‘metaphysical’ anti-Semitism aims to overcome the nihilism of the ‘Jewish Christian’ revenge [Rache] against death, a nihilism that has evolved into the technological effort to make everything secure.

Modern attitudes to meat in both men and women reflect a strong meat-masculinity association. Sex differences in the relationship between meat and masculinity have not been previously explored. In the current study we used two IATs (implicit association tasks), a visual search task, and a questionnaire to measure implicit and explicit attitudes towards meat in men and women. Men exhibited stronger implicit associations between meat and healthiness than did women, but both sexes associated meat more strongly with 'healthy' than 'unhealthy' (...) concepts, suggesting that the meat-masculinity association readily observed across western cultures may be mediated by a meat-strength/power association. The sex difference was not related to explicit attitudes to meat, nor was it attributable to a variety of other factors, such as a generally more positive disposition toward meat in men than women. Men also exhibited an attention bias toward meats, compared to non-meat foods, while females exhibited more caution when searching for non-meat foods, compared to meat. These biases were not related to implicit attitudes, but did tend to increase with increasing hunger levels. Potential ultimate explanations for these differences, including sex differences in bio-physiological needs and receptivity to social signals are discussed. (shrink)

John Norton’s argument that all formal theories of induction fail raises substantive questions about the philosophical analysis of scientific reasoning. What are the criteria of adequacy for philosophical theories of induction, explanation, or theory structure? Is more than one adequate theory possible? Using a generalized version of Norton’s argument, I demonstrate that the competition between formal and material theories in philosophy of science results from adhering to different criteria of adequacy. This situation encourages an interpretation of “formal” and “material” as (...) indicators of divergent criteria that accompany different philosophical methodologies. I characterize another criterion of adequacy associated with material theories, the avoidance of imported problems, and conclude that one way to negotiate between conflicting criteria is to adopt a pluralist stance toward philosophical theories of scientific reasoning.

According to many biologists, explaining the evolution of morphological novelty and behavioral innovation are central endeavors in contemporary evolutionary biology. These endeavors are inherently multidisciplinary but also have involved a high degree of controversy. One key source of controversy is the definitional diversity associated with the concept of evolutionary novelty, which can lead to contradictory claims (a novel trait according to one definition is not a novel trait according to another). We argue that this diversity should be interpreted in light (...) of a different epistemic role played by the concept of evolutionary novelty—the structuring of a problem space or setting of an explanatory agenda—rather than the concept’s capacity to categorize traits as novel. This distinctive role is consistent with the definitional diversity and shows that the concept of novelty benefits ongoing investigation by focusing attention on answering different questions related to comprehending the origins of novelty. A review of recent theoretical and empirical work on evolutionary novelty confirms this interpretation. (shrink)

This article analyses reaction to the ideologically inspired murder of a soldier, Lee Rigby, in central London by two converts to Islam, Michael Adebowale and Michael Adebolajo. The focus of the analysis is upon the contrast between how the event was reacted to by the UK National Press and on social media. To explore this contrast, we undertook a corpus-assisted discourse analysis to look at three periods during the event: the initial attack, the verdict of the subsequent trial and the (...) sentencing of the murderers. To do this, we constructed and analysed corpora of press and Twitter coverage of the attack, the conviction of the suspects and the sentencing of them. The analysis shows that social media and the press are intertwined, with the press exerting a notable influence through social media, but social media not always being led by the press. When looking at social media reaction to such an event as this, analysts should always consider the role that the press are playing in forming that discourse. (shrink)

The prominence of Bayesian modeling of cognition has increased recently largely because of mathematical advances in specifying and deriving predictions from complex probabilistic models. Much of this research aims to demonstrate that cognitive behavior can be explained from rational principles alone, without recourse to psychological or neurological processes and representations. We note commonalities between this rational approach and other movements in psychology – namely, Behaviorism and evolutionary psychology – that set aside mechanistic explanations or make use of optimality assumptions. Through (...) these comparisons, we identify a number of challenges that limit the rational program's potential contribution to psychological theory. Specifically, rational Bayesian models are significantly unconstrained, both because they are uninformed by a wide range of process-level data and because their assumptions about the environment are generally not grounded in empirical measurement. The psychological implications of most Bayesian models are also unclear. Bayesian inference itself is conceptually trivial, but strong assumptions are often embedded in the hypothesis sets and the approximation algorithms used to derive model predictions, without a clear delineation between psychological commitments and implementational details. Comparing multiple Bayesian models of the same task is rare, as is the realization that many Bayesian models recapitulate existing (mechanistic level) theories. Despite the expressive power of current Bayesian models, we argue they must be developed in conjunction with mechanistic considerations to offer substantive explanations of cognition. We lay out several means for such an integration, which take into account the representations on which Bayesian inference operates, as well as the algorithms and heuristics that carry it out. We argue this unification will better facilitate lasting contributions to psychological theory, avoiding the pitfalls that have plagued previous theoretical movements. (shrink)

after retiring from the practice of law in 2010, I pursued my love of philosophy. I have had the good fortune to become involved with the scholarly philosophical community, to write a small number of reviews and articles, and to present papers for conferences of the Josiah Royce Society, the APA, and the Metaphysical Society of America.As it did for so many, the pandemic led me to a time of increased solitude and reflection. I wanted to think philosophically about (...) American democracy and its ideals as the country struggled both with the pandemic and with widespread dissension and anger.The Pluralist's call for papers inviting its readers to explore their philosophical lives during the pandemic stimulated further...

Although reducing the costs of software maintenance has long been held as an important goal, few researchers have studied software maintenance — except in the context of software design. However, thinking in software design is itself muddled by the frequent confusion over the term ‘software’ and ‘programs’. In this paper we argue for a re-examination of the underlying philosophical foundations of programs, in order to establish software as a phenomenon in its own right. Once we understand the basic structure of (...) software theories, we will be in a better position to understand how theories of software relate to theories of programs. This might finally provide the insight needed to achieve the long awaited reduction in the cost of software maintenance. (shrink)

A decolonial practice and understanding of education (whether theological or otherwise) requires engaging, subverting, deposing and reimagining a whole ecology of imaginaries, practices, structures, institutionalities, traditions, power asymmetries etc.: a task that is far beyond the capacities of any individual, community or even generation. Cognisant of this reality, the article foregrounds the question of pedagogy in theological education (but only as an integral part of the colonial/decolonial ecology of education) and argues that in so far as our pedagogies in theological (...) education treat students primarily as ‘thinking creatures’, we are engaging in a dis-membering pedagogy that reproduces the coloniality of being. I identify a Cartesian anthropology (‘ego cogito sum’) – engendering a host of dualisms giving artificial supremacy to certain dimensions of reality over others – as a key animating source of dis-membering pedagogies. Drawing on the ‘pedagogical excess’ (i.e. underexplored pedagogical themes) in the theological anthropology of Simon Maimela in conversation with pedagogical visions that cohere and extend his anthropological commitments, I argue that a re-membering pedagogy is, at minimum: a pedagogy of performative action, embodiment and (community based) liminality. I argue throughout the article that in the work of re-sourcing our animating anthropologies and re-imagining our pedagogies, we are engaged in the healing work of re-membering that which coloniality has torn apart: theory and practice, mind and body, the individual and relationality, the student and the teacher, the theological school and society. Contribution: This article outlines my attempts to theoretically and theologically ground (and extend) my espoused pedagogical commitments forged at the intersection of my community work and teaching as a theological educator in an undergraduate BTh programme. This article invites other theological educators to become conscious of the theological anthropology that their espoused pedagogical commitments assume and reflect on the pedagogical commitments that their theological anthropology entails, especially as it relates to the ongoing calls for the Africanisation/decolonisation of theological education in South Africa.
