Most computational theories of cognition lack a representation of physiology. Understanding the cognitive effects of compounds present in the environment is important for explaining and predicting changes in cognition and behavior given exposure to toxins, pharmaceuticals, or the deprivation of critical compounds like oxygen. This research integrates physiologically based pharmacokinetic (PBPK) model predictions of caffeine concentrations in blood and tissues with ACT-R's fatigue module to predict the effects of caffeine on fatigue. Mapping between the PBPK model parameters and ACT-R model (...) parameters is informed by the neurophysiological literature and established associations between ACT-R modules and brain regions. The results from three such parameter mappings are explored to explain observed data from sleep-deprived participants performing the psychomotor vigilance test with and without caffeine. Predicted caffeine concentrations in the brain are used to modulate procedural parameters in the fatigue module to explain caffeine's effects on multiple performance metrics. (shrink)

Climate and evolution represents an important contribution to evolutionary biogeography, that influenced several authors, notably Karl P. Schmidt, George S. Myers, George G. Simpson, Philip J. Darlington, Ernst Mayr, Thomas Barbour, John C. Poynton, Allen Keast, Léon Croizat, Robin Craw, Michael Heads, and Osvaldo A. Reig. Authors belonging to the “New York School of Zoogeography” –a research community including Matthew, Schmidt, Myers and Simpson– accepted Matthew’s “Holarcticism” and the permanence of ocean basins and continents, whereas others, especially panbiogeographers (...) and cladistic biogeographers, were extremely critical and reacted against these ideas. “Holarcticism” has been falsified and rejected by dispersalists and the “New York School of Zoogeography” disappeared in the 1970s. Matthew, however, continues being identified by panbiogeographers and cladistic biogeographers as a key representative of classic dispersalism, helping provide some cohesion to their research communities.

Imagination plays a rich epistemic role in our cognitive lives. For example, if I want to learn whether my luggage will fit into the overhead compartment on a plane, I might imagine trying to fit it into the overhead compartment and form a justified belief on the basis of this imagining. But what explains the fact that imagination has the power to justify beliefs, and what is the structure of imaginative justification? In this paper, I answer these questions by arguing (...) that imaginings manifest an epistemic status: they are epistemically evaluable as justified or unjustified. This epistemic status grounds their ability to justify beliefs, and they accrue this status in virtue of being based on evidence. Thus, imaginings are best understood as justified justifiers. I argue for this view by way of showing how it offers a satisfying explanation of certain key features of imaginative justification that would otherwise be puzzling. I also argue that imaginings exhibit a number of markers of the basing relation, which further motivates the view that imaginings can be based on evidence. The arguments in this paper have theoretically fruitful implications not only for the epistemology of imagination, but for accounts of reasoning and epistemic normativity more generally. (shrink)

This chapter argues that epistemic uses of the imagination are a sui generis form of reasoning. The argument proceeds in two steps. First, there are imaginings which instantiate the epistemic structure of reasoning. Second, reasoning with imagination is not reducible to reasoning with doxastic states. Thus, the epistemic role of the imagination is that it is a distinctive way of reasoning out what follows from our prior evidence. This view has a number of important implications for the epistemology of the (...) imagination. For one thing, it clarifies the epistemic role of widely invoked “constraints” on the imagination. For another, it highlights important and underappreciated disanalogies between how perceptual experiences and imaginings justify beliefs. Ultimately, the view that we can reason with imagination offers an illuminating and theoretically fruitful framework through which to understand the epistemic structure of the imagination. (shrink)

MacIntyre argues that management embodies emotivism, and thus is inherently amoral and manipulative. His claim that management is necessarily Weberian is, at best, outdated, and the notion that management aims to be neutral and value free is incorrect. However, new forms of management, and in particular the increased emphasis on leadership which emerged after MacIntyre’s critique was published, tend to support his central charge. Indeed, charismatic and transformational forms of leadership seem to embody emotivism to a greater degree than do (...) more Weberian, bureaucratic forms of management; hence, MacIntyre’s central contention about our emotivistic culture seems to be well founded. Having criticised the details but defended the essence of MacIntyre’s critique of management, this paper sketches a MacIntyrean approach to management and leadership by highlighting the affinities between MacIntyre’s political philosophy and Greenleaf’s concept of servant leadership.

This book examines a main theme in religious epistemology, namely, the possibility of knowledge of God. Most often philosophers consider the rationality or justification of propositional belief about God, particularly beliefs about the existence and nature of God; and they will assess the conditions under which, if there is a God, such propositional beliefs would be knowledge, particularly in light of counter-evidence or the availability of religious disagreement. This book surveys such familiar areas, then turns toward newer and less-developed terrain: (...) interpersonal epistemology, namely what it is to know another person. It then explores the prospects for understanding what it might take to know God relationally, the contours of which are significant for many theistic traditions. (shrink)

This paper develops a theory of analog representation. We first argue that the mark of the analog is to be found in the nature of a representational system’s interpretation function, rather than in its vehicles or contents alone. We then develop the rulebound structure theory of analog representation, according to which analog systems are those that use interpretive rules to map syntactic structural features onto semantic structural features. The theory involves three degree-theoretic measures that capture three independent ways in which (...) a system can be more or less analog. We explain how our theory improves upon prior accounts of analog representation, provides plausible diagnoses for novel challenge cases, extends to hybrid systems that are partially analog and partially symbolic, and accounts for some of the advantages and disadvantages of representing analogically versus symbolically.

In his prose writings, Milton produces a reinvention of the concept of heresy, and subsequently a theological reinvention of the nature of English society. He envisions a Protestant society united by practices of individual piety and by the “heretical imperative” of autonomous choice. While Milton’s account seeks to eliminate the possibilities of religious violence and state persecution, it leads finally to the same impasse as the Lockean theory: the grounding of a right to toleration on subjective piety necessarily excludes those (...) groups who refuse to practice such piety. Nevertheless, Milton’s unique depiction of a society united by practices of heresy ultimately points toward modernity in a way that is even more remarkably prescient than Locke’s influential theory of toleration.

The first edition of The Scientific Background to Modern Philosophy took the dialogue of science and philosophy from Aristotle through to Newton. This second edition adds eight chapters, taking the dialogue through the Enlightenment and up to Darwin. This anthology is an attempt to help bridge the gap between the history of science and the history of philosophy.

This paper initiates analytic inquiry into the metaphysics of masculinity. I argue that individual masculinities (such as ‘clone masculinity’ and ‘incel masculinity’) are distinct homeostatic property cluster kinds related to gender structures via processes of adherence, failed-adherence, selective adherence, and/or reinterpretation with respect to male-coded social norms.

The notion that business organizations are akin to Aristotelian political communities has been a central feature of research into virtue ethics in business. In this article, I begin by outlining this “community thesis” and go on to argue that psychological research into the “just world fallacy” presents it with a significant challenge. The just world fallacy undermines our ability to implement an Aristotelian conception of justice, to each as he or she is due, and imperils the relational equality required for (...) shared participation in communities. In the final section, I offer a description of what Aristotelian community might look like within organizations, and some suggestions about how it may be possible to resist the challenge posed by the just world fallacy.

Dialogues generated over a year of weekly meetings with 8 children at a school in Edinburgh. The author and the children attempted to craft stories reflecting philosophical problems.

A probability distribution is regular if it does not assign probability zero to any possible event. While some hold that probabilities should always be regular, three counter-arguments have been posed based on examples where, if regularity holds, then perfectly similar events must have different probabilities. Howson and Benci et al. have raised technical objections to these symmetry arguments, but we see here that their objections fail. Howson says that Williamson’s “isomorphic” events are not in fact isomorphic, but Howson is speaking (...) of set-theoretic representations of events in a probability model. While those sets are not isomorphic, Williamson’s physical events are, in the relevant sense. Benci et al. claim that all three arguments rest on a conflation of different models, but they do not. They are founded on the premise that similar events should have the same probability in the same model, or in one case, on the assumption that a single rotation-invariant distribution is possible. Having failed to refute the symmetry arguments on such technical grounds, one could deny their implicit premises, which is a heavy cost, or adopt varying degrees of instrumentalism or pluralism about regularity, but that would not serve the project of accurately modelling chances.

Despite the growing profile of ‘implementation science’, its status as a field of study remains ambiguous. Implementation science originates in the evidence-based movement and attempts to broaden the scope of evidence-based medicine to improve ‘clinical effectiveness’ and close the ‘implementation gap’. To achieve this agenda, implementation science draws on methodologies from the social sciences to emphasise coherence between qualitative and quantitative approaches. In so doing, we ask if this is at the expense of ignoring the dominating tendencies of the evidence-based (...) movement and consider if some of the methodologies being drawn on should be considered irreconcilable with evidence-based methodologies.

ABSTRACT The primary aim of the paper is to apply the concept of retribution to nuclear defence policy. Nuclear defence policy, as I conceive it, is concerned with addressing the threat Soviet nuclear weapons pose for Western security. I argue that, contrary to popular opinion, MAD is not a retributive doctrine—that in fact it violates two constitutive principles of retribution: culpability and proportionality. After explicating these constitutive principles, I apply them to retaliatory strategy—showing that the culpability criterion restricts retaliation to (...) the agents of aggression while the proportionality criterion requires a just measure of retaliation. The result is a defence policy continuous with the just war tradition—one which rules out deterrence based on threats against the civilian population. I show why a retributive policy requires non‐nuclear forces and discuss the feasiblity of replacing all nuclear forces with conventional weapons. I anticipate and answer major objections to the denuclearization of U.S. and NATO forces. Finally, I conclude that an advocate of a retributive policy—specifically, a policy calling for a proportional or measured response against combatants only—must be willing, in the name of justice, to accept the risk of making war more thinkable by making it less horrible.

In this chapter, we follow Edward Craig?s advice: ask what the concept of knowledge does for us and use our findings as clues about its application conditions. What a concept does for us is a matter of what we can do with it, and what we do with concepts is deploy them in thought and language. So, we will examine the purposes we have in attributing knowledge. This chapter examines two such purposes, agent evaluation and informant-suggestion, and brings the results (...) to bear on an important debate about the application conditions of the concept of knowledge?the debate between contextualists and their rivals.

Background Despite the growth of biomedical research in South Africa, there are few insights into the operation of Research Ethics Committees (RECs) in this setting. We investigated the composition, operations and training needs of health RECs in South Africa against the backdrop of national and international guidelines. Methods The 12 major health RECs in South Africa were surveyed using semi-structured questionnaires that investigated the composition and functions of each REC as well as the operational issues facing committees. Results Health RECs (...) in SA have an average of 16 members and REC members are predominantly male and white. Overall, there was a large discrepancy in findings between under-resourced RECs and well resourced RECs. The majority of members (56%) are scientists or clinicians who are typically affiliated to the same institution as the health REC. Community representatives account for only 8% of membership. Training needs for health REC members varied widely. Conclusion Most major health RECs in South Africa are well organized given the resource constraints that exist in relation to research ethics in developing countries. However, the gender, racial and occupational diversity of most of these RECs is suboptimal, and most RECs are not constituted in accordance with South African guidelines. Variability in the operations and training needs of RECs is a reflection of apartheid-entrenched influences in tertiary education in SA. While legislation now exists to enforce standardization of research ethics review systems, no provision has been made for resources or capacity development, especially to support historically-disadvantaged institutions. Perpetuation of this legacy of apartheid represents a violation of the principles of justice and equity. (shrink)

Recent research on the evolution of religion has focused on whether religion is an unselected by-product of evolutionary processes or if it is instead an adaptation by natural selection. Adaptive hypotheses for religion include direct fitness benefits from improved health and indirect fitness benefits mediated by costly signals and/or cultural group selection. Herein, I propose that religious denominations achieve indirect fitness gains for members through the use of ecologically arbitrary beliefs, rituals, and moral rules that function as recognition markers of (...) cultural inheritance analogous to kin and species recognition of genetic inheritance in biology. This recognition signal hypotheses could act in concert with either costly signaling or cultural group selection to produce evolutionarily altruistic behaviors within denominations. Using a cultural phylogenetic analysis, I show that a large set of religious behaviors among extant Christian denominations supports the prediction of the recognition signal hypothesis that characters change more frequently near historical schisms. By incorporating demographic data into the model, I show that more-distinctive denominations, as measured through dissimilar characteristics, appear to be protected from intrusion by nonmembers in mixed-denomination households, and that they may be experiencing greater biological growth of their populations even in the present day.

Shared agency is a distinctive kind of sociality that involves interdependent planning, practical reasoning, and action between participants. Philosophical reflection suggests that agents engage in this form of sociality when a special structure of interrelated psychological attitudes exists between them, a set of attitudes that constitutes a collective intention. I defend a new way to understand collective intention as a combination of individual conditional intentions. Revising an initial statement of the conditional intention account in response to several challenges leads to (...) a specification of the properties these intentions need to have in order to be genuine commitments. I then show how a structure of conditional intentions with these properties settles a collection of agents on engaging in social interactions that display all the features typically associated with shared agency.

Gareth Matthews suggests that we can better understand the nature of philosophical inquiry if we recognize the central role played by perplexity. The seminal representation of philosophical perplexity is in Plato's dialogues; Matthews examines the intriguing shifts in Plato's attitude to perplexity and suggests that these may represent a course of philosophical development that philosophers follow even today.

A widely cited roadblock to bridging ecological psychology and enactivism is that the former identifies with realism and the latter identifies with constructivism, which critics charge is subjectivist. A pragmatic reading, however, suggests non-mental forms of constructivism that simultaneously fit core tenets of enactivism and ecological realism. After advancing a pragmatic version of enactive constructivism that does not obviate realism, I reinforce the position with an empirical illustration: Physarum polycephalum (a slime mold), a communal unicellular organism that leaves slime trails (...) that form chemical barriers that it avoids in foraging explorations. Here, environmental building and sensorimotor engagement are part of the same process with P. polycephalum coordinating around self-created, affordance-bearing geographies, which nonetheless exist independently in ways described by ecological realists. For ecological psychologists, affordances are values, meaning values are external to the perceiver. I argue that agent-enacted values have the same status and thus do not obviate ecological realism or generate subjectivism. The constructivist-realist debate organizes around the emphasis that enactivists and ecological theorists respectively place on the inner constitution of organisms vs. the structure of environments. Building on alimentary themes introduced in the P. polycephalum example and also in Gibson’s work, I go on to consider how environment, brain, visceral systems, and even bacteria within them enter perceptual loops. This highlights almost unfathomable degrees of mutually modulating internal and external synchronization. It also shows instances in which internal conditions alter worldly configurations and invert values, in Gibson’s sense of the term, albeit without implying subjectivism. My aim is to cut across the somatic focus of enactive constructivism and the external environment-oriented emphasis of ecological realism and show that enactivism can enrich ecological accounts of value.

Imagine I hold up a Granny Smith apple for all to see. You would thereby gain justified beliefs that it was green, that it was apple, and that it is a Granny Smith apple. Under classical foundationalism, such simple visual beliefs are mediately justified on the basis of reasons concerning your experience. Under dogmatism, some or all of these beliefs are justified immediately by your experience and not by reasons you possess. This paper argues for what I call the looks (...) view of the justification of simple visual beliefs. According to the looks view, such beliefs are mediately justified on the basis of reasons concerning how the relevant things look. Unlike under classical foundationalism, under the looks view as I develop it, these reasons are public. They are public with respect to both their content and possession: with respect to content, they are not about ourselves and our experiences, and with respect to their possession, many people can have the very same looks-related reasons.

An important theme in recent experimental philosophy is that certain judgements (e.g. our judgements involving intentional action and causation) exhibit a kind of normative penetration whereby, in spite of a not-obviously-normative subject matter, they turn out to be sensitive to, and co-vary with, our normative attitudes in interesting and surprising ways. We present the results of several new experimental studies that suggest that our judgements about feasibility also appear to exhibit this kind of normative penetration in at least some cases; (...) that the best explanation of it involves attributing to subjects a certain kind of extensional error that results from conflating the question at hand with another question that is more salient given their normative attitudes; and that these conclusions have significant, though not straightforward, implications for our understanding of both normative penetration and feasibility, respectively.

I distinguish two ways of explaining our capacity for ‘transparent’ knowledge of our own present beliefs, perceptions, and intentions: an inferential and a reflective approach. Alex Byrne (2011) has defended an inferential approach, but I argue that this approach faces a basic difficulty, and that a reflective approach avoids the difficulty. I conclude with a brief sketch and defence of a reflective approach to our transparent self-knowledge, and I show how this approach is connected with the thesis that we must (...) distinguish between a kind of self-knowledge that is of oneself as agent and another kind that is of oneself as patient.

Research that involves the creation of animals with human-derived parts opens the door to potentially valuable scientific and therapeutic advances, yet invokes unsettling moral questions. Critics and champions alike stand to gain from clear identification and careful consideration of the strongest ethical objections to this research. A prevailing objection argues that crossing the human/nonhuman species boundary introduces inexorable moral confusion (IMC) that warrants a restriction to this research on precautionary grounds. Though this objection may capture the intuitions of many who (...) find this research unsettling, it relies on mistaken views of both biology and moral standing, ultimately distorting the morally relevant facts. We critically examine IMC, identify mistaken essentialist assumptions, and reframe ethical concerns. The upshot is a stronger line of objection that encourages a more inclusive and productive ethical discourse. (shrink)

Recently, many philosophers of religion have sought to defend the rationality of religious belief by shifting the burden of proof onto the critic of religious belief. Some have appealed to extraordinary religious experience in making their case. Religious Experience, Justification, and History restores neglected explanatory and historical considerations to the debate. Through a study of William James, it contests the accounts of religious experience offered in recent works. Through reflection on the history of philosophy, it also unravels the philosophical use (...) of the term justification. Matthew Bagger argues that the commitment to supernatural explanations implicit in the religious experiences employed to justify religious belief contradicts the modern ideal of human flourishing.

This paper argues that a class of popular views of collective intention, which I call “quasi-psychologism”, faces a problem explaining common intuitions about collective action. Views in this class hold that collective intentions are realized in or constituted by individual, mental, participatory intentions. I argue that this metaphysical commitment entails persistence conditions that are in tension with a purported obligation to notify co-actors before leaving a collective action attested to by participants in experimental research about the interpersonal normativity of collective (...) action. I then explore the possibilities open to quasi-psychologists for responding to this research. (shrink)
