It is clear throughout Cognitive Gadgets Heyes believes the development of cognitive capacities results from the interaction of genes and experience. However, she opposes cognitive instincts theorists to her own view that uniquely human capacities are cognitive gadgets. Instinct theorists believe that cognitive capacities are substantially produced by selection, with the environment playing a triggering role. Heyes’s position is that humans have similar general learning capacities to those present across taxa, and that sophisticated human cognition is substantially created by our (...) socioculturally transmitted environment. It is a core strategy of Heyes to provide evidence of learning altering a cognitive capacity to conclude that a capacity is a cognitive gadget and not an instinct. We draw on recent work on the evolution of learning preparedness to examine the adequacy of this strategy. In particular, we analyse experimental evolution work showing how selection affects cognition within the laboratory. First, this work reveals that change due to learning can still be retained under genetic assimilation. This suggests that domain-specific adaptation can coexist with learning, moderate nativism, an option missed by the instinct versus gadget distinction. Second, we describe the conditions that select for increased preparedness in learning: certainty, reliability, and particular costs. We consider how these conditions can be used when conducting evolutionary reasoning about cognition, applying them to the important capacity for imitation. We find that the conditions lend theoretical support to moderate nativism about the capacity to imitate, which is supported by psychological evidence. (shrink)

The Social Theory of Practices effectively criticized conceptions of social practices as rule-governed or regularity-exhibiting performances. Turner’s criticisms nevertheless overlook an alternative, "normative" conception of practices as constituted by the mutual accountability of their performances. Such a conception of practices also allows a more adequate understanding of normativity in terms of accountability to what is at issue and at stake in a practice. We can thereby understand linguistic practice and normative authority without having to posit stable meanings, rules, norms, (...) or presuppositions underlying the manifest diversity of social life. Key Words: normativity • practices • rules • language. (shrink)

In this reply, I raise some questions about the account of "normativity" given by Joseph Rouse. I discuss the historical form of disputes over normativity in such thinkers as Kelsen and show that the standard issue with these accounts is over the question of whether there is anything added to the normal stream of explanation by the problem of normativity. I suggest that Rouse’s attempt to avoid the issues that arise with substantive explanatory theories of practices of the (...) kind criticized in The Social Theory of Practices leads to a result that is uninformative, and the strategy raises the question of whether there is anything there to explain and thus whether there is any necessity to appeal to the kind of anomalous explanations the normativist offers. Key Words: Kelsen • normativity • Mauss • naturalism • practices. (shrink)

Practice Then and Now "Practice theory" has a long history in philosophy, under various names, but current practice theory is a response to failures of projects of modernity or enlightenment which attempt to reduce science or politics to formulae. Heidegger, Oakeshott, and MacIntyre are each examples of philosophers who turned to practice conceptions. Foucault and Bourdieu made similar turns. Practice accounts come in different forms: some emphasize skill-like individual accomplishments, others emphasize the social character or presupposition-like character of the tacit (...) conditions of activities. The Social Theory of Practices problematized the idea of sameness, the idea that participants in an activity had the same tacit possessions, which undermined the idea that practices were collective objects in which individuals participated. Later critics, such as Schatzki and Rouse, emphasized the normative coherence and character of practice, which has a collective aspect. Pickering and others suggested a notion of practices that was de-mentalized and focused on the objects that were part of the practical activity, which provided for the continuity and sociality of practice without collectivizing its mental content. The discovery of mirror neurons suggested a non-collective mode of transmission of practices. The implications of these developments can be seen in connection with ethics, where the conflict between the ethical and the practical can be understood in terms of the intrinsic conflict between the need to behave successfully and our learned ethical intuitions.

I argue that the distance between state and citizen gives state paternalism a pro tanto advantage over paternalism between individuals. Pace Jonathan Quong, the state neither denies nor diminishes my moral status by acting on a justified negative judgment about my rational or volitional capacities. Nor does its failure to paternalize on the basis of detailed information about individuals constitute a source of disrespect. Rather, the less discriminating nature of general legislation both reduces the risk of social stigmatization and avoids (...) a problematic dynamic with the paternalizee. But paternalistic policies may give us reason to be concerned about superiority or contempt in policy-makers towards the citizens at whom they are directed. Governments must remain ‘faceless’ enough for paternalism to operate at a distance, but they must reassure the governed that the judgment that they can do better for them does not conceal the attitude that they are better than them.

Philosophers and cognitive scientists have worried that research on animal mind-reading faces a ‘logical problem’: the difficulty of experimentally determining whether animals represent mental states (e.g. seeing) or merely the observable evidence (e.g. line-of-gaze) for those mental states. The most impressive attempt to confront this problem has been mounted recently by Robert Lurz. However, Lurz' approach faces its own logical problem, revealing this challenge to be a special case of the more general problem of distal content. Moreover, participants in this (...) debate do not agree on criteria for representation. As such, future debate should either abandon the representational idiom or confront underlying semantic disagreements. (shrink)

A surge of empirical research demonstrating flexible cognition in animals and young infants has raised interest in the possibility of rational decision‐making in the absence of language. A venerable position, which I here call “Classical Inferentialism”, holds that nonlinguistic agents are incapable of rational inferences. Against this position, I defend a model of nonlinguistic inferences that shows how they could be practically rational. This model vindicates the Lockean idea that we can intuitively grasp rational connections between thoughts by developing the (...) Davidsonian idea that practical inferences are at bottom categorization judgments. From this perspective, we can see how similarity‐based categorization processes widely studied in human and animal psychology might count as practically rational. The solution involves a novel hybrid of internalism and externalism: intuitive inferences are psychologically rational (in the explanatory sense) given the intensional sensitivity of the similarity assessment to the internal structure of the agent's reasons for acting, but epistemically rational (in the justificatory sense) given an ecological fit between the features matched by that assessment and the structure of the agent's environment. The essay concludes by exploring empirical results that show how nonlinguistic agents can be sensitive to these similarity assessments in a way that grants them control over their opaque judgments.

The chapter develops a taxonomy of views about the epistemic responsibilities of citizens in a democracy. Prominent approaches to epistemic democracy, epistocracy, epistemic libertarianism, and pure proceduralism are examined through the lens of this taxonomy. The primary aim is to explore options for developing an account of the epistemic responsibilities of citizens in a democracy. The chapter also argues that a number of recent attacks on democracy may not adequately register the availability of a minimal approach to the epistemic responsibilities (...) of citizens in a democracy.

The standard methodology of comparative psychology has long relied upon a distinction between cognition and ‘mere association’; cognitive explanations of nonhuman animals behaviors are only regarded as legitimate if associative explanations for these behaviors have been painstakingly ruled out. Over the last ten years, however, a crisis has broken out over the distinction, with researchers increasingly unsure how to apply it in practice. In particular, a recent generation of psychological models appear to satisfy existing criteria for both cognition and association. (...) Salvaging the standard methodology of comparative psychology will thus require significant conceptual redeployment. In this article, I trace the historical development of the distinction in comparative psychology, distinguishing two styles of approach. The first style tries to make out the distinction in terms of the properties of psychological models, for example by focusing on criteria like the presence of rules & propositions vs. links & nodes. The second style of approach attempts to operationalize the distinction by use of specific experimental tests for cognition performed on actual animals. I argue that neither style of criteria is self-sufficient, and both must cooperate in an iterative empirical investigation into the nature of animal minds if the distinction is to be reformed.

A prominent objection to the knowledge norm of belief is that it is too demanding or too strong. The objection is commonly framed in terms of the idea that there is a tight connection between norm violation and the appropriateness of criticism or blame. In this paper I do two things. First, I argue that this way of motivating the objection leads to an impasse in the epistemic norms debate. It leads to an impasse when knowledge normers invoke excuses to (...) explain away a prima facie connection between blamelessness and justified belief. Second, I argue that a way out of the impasse becomes available when we take a closer look at some distinctions in the theory of responsibility. There are at least three different notions of responsibility relevant here. I argue that a weaker notion of responsibility – attributability – should be used to motivate the objection that the knowledge norm of belief is too strong. Insofar as the proposal motivates the objection without appeal to blamelessness, it opens up space to move beyond the impasse. (shrink)

For most of the 20th century, it was possible to regard fertilisation as the identifiable point when life begins, because this moment could be defined unequivocally and was thought to be the single most essential biological step in the establishment of a new human entity. Since the successful reproductive cloning of Dolly and other mammals, it is clear that any human cell has the potential to supply the full genome of an embryo, and hence a person, without going through fertilisation. (...) At what point in time do such embryos acquire the respect accorded to human beings? The authors argue that the time of implantation is the most useful point at which the potential and the intention to create a new person are translated into reality, because from that point a new life develops. Implantation differentiates a somatic cell in culture from a human entity that has acquired its own identity and developmental potential. The authors examine the value of quickening or viability as alternative developmental stages in the process of acquiring respect for the Dolly embryo. (shrink)

This article addresses the long-standing problem of how to understand Mill’s famous harm principle in light of his failure to specify what counts as “harm” in On Liberty. I argue that standard accounts restricting “harm” to only certain negative consequences fail to do justice to the text, and that this fact forces us to rethink Mill’s defense of individual liberty. I then offer a new account of that defense in which “harm” is understood in an expansive sense, despite apparent problems (...) for such a view. (shrink)

Liberty-restricting measures have been implemented for centuries to limit the spread of infectious diseases. This article considers if and when it may be ethically acceptable to impose selective liberty-restricting measures in order to reduce the negative impacts of a pandemic by preventing particularly vulnerable groups of the community from contracting the disease. We argue that the commonly accepted explanation—that liberty restrictions may be justified to prevent harm to others when this is the least restrictive option—fails to adequately accommodate the complexity (...) of the issue or the difficult choices that must be made, as illustrated by the COVID-19 pandemic. We introduce a dualist consequentialist approach, weighing utility at both a population and individual level, which may provide a better framework for considering the justification for liberty restrictions. While liberty-restricting measures may be justified on the basis of significant benefits to the population and small costs for overall utility to individuals, the question of whether it is acceptable to discriminate should be considered separately. This is because the consequentialist approach does not adequately account for the value of equality. This value may be protected through the application of an additional proportionality test. An algorithm for making decisions is proposed. Ultimately whether selective liberty-restricting measures are imposed will depend on a range of factors, including how widespread infection is in the community, the level of risk and harm a society is willing to accept, and the efficacy and cost of other mitigation options.

Orthodoxy says that the thesis that composition is identity (CAI) entails universalism: the claim that any collection of entities has a sum. If this is true it counts in favour of CAI, since a thesis about the nature of composition that settles the otherwise intractable special composition question (SCQ) is desirable. But I argue that it is false: CAI is compatible with the many forms of restricted composition, and SCQ is no easier to answer given CAI than otherwise. Furthermore, in (...) seeing why this is the case we reveal an objection to CAI: that it allows for the facts concerning what there is to be settled whilst leaving open the question about what is identical to what.

Proponents of ground, which is used to indicate relations of ontological fundamentality, insist that ground is a unified phenomenon, but this thesis has recently been criticized. I will first review the proponents' claims for ground's unicity, as well as the criticisms that ground is too heterogeneous to do the philosophical work it is supposed to do. By drawing on Aristotle's notion of homonymy, I explore whether ground's metaphysical heterogeneity can be theoretically accommodated while at the same time preserving its proponents' (...) desideratum that it be a unified phenomenon.

In recent decades, scholarship in the history of science has explored the emergence and development of sciences in which fields serve as privileged sites of knowledge production. Much of this work has focused on the field sciences’ formative period from the late nineteenth century to the mid-twentieth century, and it is the definitions of the field, fieldwork, and field science emerging from the study of this period that have come to dominate the historical literature. Those definitions cannot, however, account for (...) transformations that have taken place across many field sciences since the mid-twentieth century.

Research suggests that the reaching hand automatically deviates toward a target that changes location during the reach. In the current study, we investigated whether movement intention can influence the target jump’s impact on the hand. We compared the degree of trajectory deviation to a jumped target under three instruction conditions: GO, in which participants were told to go to the target if it jumped, STOP, in which participants were told to immediately stop their movement if the target jumped, and IGNORE, (...) in which participants were told to ignore the target if it jumped and to continue to its initial location. We observed a reduced response to the jump in the IGNORE condition relative to the other conditions, suggesting that the response to the jump is contingent on the jump being a task-relevant event.

In this paper I argue that there are some sentences whose truth makes no demands on the world, being trivially true in that their truth-conditions are trivially met. I argue that this does not amount to their truth-conditions being met necessarily: we need a non-modal understanding of the notion of the demands the truth of a sentence makes, lest we be blinded to certain conceptual possibilities. I defend the claim that the truths of pure mathematics and set theory are trivially (...) true, and hence accepting their truth brings no ontological commitment; I further defend the claim that the truths of applied mathematics and set theory do not demand the existence of numbers or sets. While the notion of a demand must not be reduced to anything modal, I nonetheless argue that sentences that are trivially true must also be necessary, lest we violate a very weak version of the principle that truth depends on the world. I further argue that all necessary truths are trivially true, lest we admit unexplained necessities. I end by showing one important consequence of this: I argue that if there are truthmakers for intrinsic predications, they must be states of affairs rather than tropes. (shrink)

Recent work in social psychology suggests that people harbor “implicit race biases,” biases which can be unconscious or uncontrollable. Because awareness and control have traditionally been deemed necessary for the ascription of moral responsibility, implicit biases present a unique challenge: do we pardon discrimination based on implicit biases because of its unintentional nature, or do we punish discrimination regardless of how it comes about? The present experiments investigated the impact such theories have upon moral judgments about racial discrimination. The results (...) show that different theories differ in their impact on moral judgments: when implicit biases are defined as unconscious, people hold the biased agent less morally responsible than when these biases are defined as automatic (i.e., difficult to control), or when no theory of implicit bias is provided.

Does Aristotle offer a definition of the soul? In fact, he rejects the possibility of defining the soul univocally. Because “life” is a homonymous concept, so too is “soul”. Given the specific causal role that Aristotle envisages for form and essence, the soul requires multiple different definitions to capture how it functions as a cause in each form of life. Aristotle suggests demonstrations can be given which express these causal definitions; I reconstruct these demonstrations in the paper.

_Normativity and Naturalism in the Social Sciences_ engages with a central debate within the philosophy of social science: whether social scientific explanation necessitates an appeal to norms, and if so, whether appeals to normativity can be rendered "scientific." This collection brings together contributions from a diverse group of philosophers who explore a broad but thematically unified set of questions, many of which stem from an ongoing debate between Stephen Turner and Joseph Rouse on the role of naturalism in (...) the philosophy of the social sciences. Informed by recent developments in both philosophy and the social sciences, this volume will set the benchmark for contemporary discussions about normativity and naturalism. This collection will be relevant to philosophers of social science, philosophers in interested in the rule following and metaphysics of normativity, and theoretically oriented social scientists.

In A Dentist and a Gentleman the sociologist Tracey Adams retells a familiar professionalization story, this time about elite dental practitioners in nineteenth‐century Ontario who launched a status‐enhancement project to reshape their self‐ and public image into “professional gentlemen” and establish monopoly control over dental practice. Dentists secured legislation in 1868 giving them authority to set entrance requirements, test and license practitioners, and establish a college. In subsequent decades they campaigned against those they called “quacks” who practiced without a license, (...) advertised, charged low fees, maintained dirty offices, misled patients about pain, or brought the gentlemanly status of dentistry into disrepute.Despite early resistance, the project had mostly succeeded by 1918, as dentists skillfully linked their expertise to emerging public health concerns and a professional image subtly reoriented toward an ideal of public service. By 1900 dental rhetoric was warning Canadians of an impending crisis of tooth decay and dental disease that would bring physical deterioration and mass feeblemindedness in its wake. Racial degeneracy, dentists warned, began in the mouth; the advance of civilization produced too much soft food and sugar, too little chewing, and too many high‐strung and overindulgent mothers. Only dentists, as “sentinels at the portal of the alimentary tract” , could stand against this threat to Anglo‐Saxon civilization. Rhetoric like this, combined with doses of guilt heaped on mothers, teachers, school boards, and public health agencies, resulted by 1915 in regular dental inspections of schoolchildren, free dental clinics, and the creation of the army dental corps.Dentistry brought unique twists to this familiar professionalization story. Prior to 1860 dentistry was an especially low‐status craft, associated with uneducated, itinerant tooth‐drawers or craftsmen like blacksmiths and gunsmiths . Professionalizing dentists therefore felt a special imperative to recast themselves as “gentlemen”; this image also reassured the upper‐middle‐class women who were dentists' main clientele. Unexpectedly, as Adams shows in an intriguing analysis, dentists benefited from an invaluable social alliance with physicians, who offered no opposition of the sort they raised against other rival groups of healers to dentists' professional aspirations.The study deals extensively with how gender shapes professions. Dentistry's professionalization, Adams insists, involved the adoption of a new ideal of personal masculinity, as seen in admonitions to dentists to establish firm, courteous, expert authority over their clients and in dentists' efforts to shape the imagined persona of the ideal dental assistant as uniquely female and wifelike. This masculine crafting of the profession notwithstanding, Ontario dentists evinced less overt opposition to women aspirants than did doctors or lawyers. Nevertheless, the proportion of female practitioners was much lower in dentistry than in medicine or law and remains substantially lower today. Adams brings considerable insight to her discussion of these facts and their causes, and she presents useful comparisons among the professions.This study has a few limitations. Perhaps because the author's sources are mainly professional journals, her account mostly mirrors the outlook of the professionalizing elite and her prose occasionally adopts their moralizing and improving tone. Regrettably, the book deals scarcely at all with what dentists actually did. One learns little about how changing scientific and medical ideas affected dentists' work, how dentists utilized anaesthesia and coped with the problem of pain, and what controversies over diagnostics and treatment animated the profession or about dentists' training and income. This is a history of dentistry's professionalization, not of dental medicine per se. But Isis readers impressed by this solid and modest study will hope that a history of dental practice will be Tracey Adams's next project. (shrink)

There is evidence that the practice of meditative reading was cultivated by Hellenistic Jews as a discipline analogous to the spiritual exercises of the philosophical schools. The present study traces (1) the Deuteronomic antecedents of this practice, (2) its reconfiguration in the Torah Psalms, and (3) finally its expression in Greco-Jewish translation, with special reference to the Greek Psalter. Taking its cue from the work of Pierre Hadot, it situates this development within the larger matrix of Hellenistic philosophical discourse. The (...) philological focus of the study is the use of the Hebrew verb I הגה Qal in contexts where Torah study is thematic and its rendering by μελετάω in the Septuagint. To frame the lexical analysis, it draws on the slot-filler model pioneered by Charles Fillmore. Contribution: This article situates a key Greco-Jewish translation with reference to both its Deuteronomic antecedents and to practices cultivated within the philosophical schools of the Hellenistic period. The analysis demonstrates the relevance of Frame Semantics to philological investigation. (shrink)

BackgroundDelirium is highly prevalent in the general hospital patient population, characterized by acute onset, fluctuating levels of consciousness, and global impairment of cognitive functioning. Mental capacity, its assessment and subsequent consent are therefore prominent within this cohort, yet under-explored.AimThis study of patients with delirium sought to determine the processes by which consent to medical treatment was attempted, how capacity was assessed, and any subsequent actions thereafter.MethodA retrospective documentation review of patients identified as having a delirium for the twelve months February (...) 2013 to January 2014 was undertaken. Inclusion and exclusion criteria were used; demographic and descriptive data collected. A total of n=1153 patients were identified with n=310 meeting inclusion criteria.ResultA random sample of one hundred patients were subsequently reviewed. One third of patients had documentation relating to consent, while four patients had documentation relating to capacity. Median delirium duration was three days, with treatment refusal occurring in twenty-two patients and “duty of care” being used as an apparent beneficent related treatment framework in twelve patients.ConclusionsWhile impaired decision-making was indicated, the review was unable to indicate what patient characteristics flag the need for capacity assessment. Documentation relating to consent processes appeared deficient for this cohort. (shrink)

In ‘A New Route to the Necessity of Origin’, Rohbraugh and deRosset offer an argument for the Necessity of Origin appealing neither to Suffciency of Origin nor to a branching-times model of necessity.

In this response, we object that their argument is question-begging by showing, first, that the locality of prevention thesis is not strong enough to satisfactorily derive from it the intended (...) conclusion, and, second, that the argument is not sound unless the Necessity of Origin is operating as an implicit premiss.

Mill argues that, apart from the principle of utility, his utilitarianism is incompatible with absolutes.

In this paper I argue that warrant for Lewis’ Modal Realism is unobtainable. I consider two familiar objections to Lewisian realism – the modal irrelevance objection and the epistemological objection – and argue that Lewis’ response to each is unsatisfactory because they presuppose claims that only the Lewisian realist will accept. Since, I argue, warrant for Lewisian realism can only be obtained if we have a response to each objection that does not presuppose the truth of Lewisian realism, this circularity (...) is vicious. I end by contrasting Lewis’ methodology with Forrest’s in order to illustrate a rival method that does not fall victim to the objection I lay against Lewis. (shrink)

In Christ Meets Me Everywhere, Michael Cameron argues that Augustine wanted to train readers of Scripture to transpose themselves into the texts in the same way he did, by the same process of figuration that he found at its core. Tracking Augustine's developing practice of self-transposition into the figures of the biblical texts over the course of his entire career, Cameron shows that this practice is the key to Augustine's hermeneutics.

In the maximal form of indirect development found in many taxa of marine invertebrates, embryonic cell lineages of fixed fate and limited division capacity give rise to the larval structures. The adult arises from set‐aside cells in the larva that are held out from the early embryonic specification processes, and that retain extensive proliferative capacity. We review the locations and fates of set‐aside cells in two protostomes, a lophophorate and a deuterostome. The distinct adult body plans of many phyla develop (...) from homologous set‐aside cells within homologous larvae. We argue that the stocks from which these phyla arose utilized these respective larvae, and the diversity of their adult body plans reflects diverse pattern formation processes executed in their set‐aside cell populations. Chordates and arthropods develop directly, but share adult characters with indirectly developing phyla. Thus the deuterostome and protostome stocks that were ancestral to chordates and arthropods, respectively, also utilized maximal indirect development. (shrink)

Interest in philosophical anthropology in the early twelfth century was limited to the logical question of how to think and speak about dead humans. This question was prompted by the logic of living and dead humans based on the doctrine of substance found in Aristotle’s Categories and in the division of substance, as outlined by Porphyry to exemplify the logic of genus and species relations in the Isagoge. Abelard held the view that there is no such thing as a dead (...) human, and this provoked an intense response from his contemporaries. Abelard’s contemporaries, including Alberic of Paris and other anonymous authors, mounted a number of arguments against Abelard’s views. The stakes were high for them: as realists about species and genera, Abelard’s denial that there are dead humans threatened their entire interpretation of the structure of species and genera, and thereby their theory of universals.
