Behavioral evidence for the COVIS dual‐process model of category learning has been widely reported in over a hundred publications (Ashby & Valentin, ). It is generally accepted that the validity of such evidence depends on the accurate identification of individual participants' categorization strategies, a task that usually falls to Decision Bound analysis (Maddox & Ashby, ). Here, we examine the accuracy of this analysis in a series of model‐recovery simulations. In Simulation 1, over a third of simulated participants using an (...) Explicit (conjunctive) strategy were misidentified as using a Procedural strategy. In Simulation 2, nearly all simulated participants using a Procedural strategy were misidentified as using an Explicit strategy. In Simulation 3, we re‐examined a recently reported COVIS‐supporting dissociation (Smith et al., ) and found that these misidentification errors permit an alternative, single‐process, explanation of the results. Implications for due process in the future evaluation of dual‐process theories, including recommendations for future practice, are discussed. (shrink)

Frank Plumpton Ramsey (1903–30) made seminal contributions to philosophy, mathematics and economics. Whilst he was acknowledged as a genius by his contemporaries, some of his most important ideas were not appreciated until decades later; now better appreciated, they continue to bear an influence upon contemporary philosophy. His historic significance was to usher in a new phase of analytic philosophy, which initially built upon the logical atomist doctrines of Bertrand Russell and Ludwig Wittgenstein, raising their ideas to a new level of (...) sophistication, but ultimately he became their successor rather than remain a mere acolyte.

The mouse t-complex, located on chromosome 17, contains genes known to influence male, but not female, fertility. Although some t-complex genes are recessive lethals, t-chromosomes are maintained in the population by transmission ratio distortion. When male mice heterozygous for the t-chromosome mate with wild-type females, most offspring will possess the t-chromosome, indicating a link between t-complex genes and sperm function. Several proteins coded for by t-complex genes have been localised in the sperm flagellum, suggesting roles relating to motility. Another t-complex (...) protein appears able to regulate the adenylyl cyclase/cAMP signal transduction pathway, known to play an important role in capacitation. Defective motility and/or failure to capacitate (“switch on”) would result in poorly fertile or infertile spermatozoa. Given the existence of human homologues for many genes in the t-complex and the prevalence of “male factor” infertility, information obtained about the t-complex not only will provide insight into basic biological mechanisms but may be of future clinical relevance as well.

This volume contains thirteen papers that were presented at the 2017 Annual Meeting of the Canadian Society for History and Philosophy of Mathematics/Société canadienne d’histoire et de philosophie des mathématiques, which was held at Ryerson University in Toronto. It showcases rigorously reviewed modern scholarship on an interesting variety of topics in the history and philosophy of mathematics from Ancient Greece to the twentieth century. A series of chapters all set in the eighteenth century consider topics such as John Marsh’s techniques (...) for the computation of decimal fractions, Euler’s efforts to compute the surface area of scalene cones, a little-known work by John Playfair on the practical aspects of mathematics, and Monge’s use of descriptive geometry. After a brief stop in the nineteenth century to consider the culture of research mathematics in 1860s Prussia, the book moves into the twentieth century with an examination of the historical context within which the Axiom of Choice was developed and a paper discussing Anatoly Vlasov’s adaptation of the Boltzmann equation to ionized gases. The remaining chapters deal with the philosophy of twentieth-century mathematics through topics such as an historically informed discussion of finitism and its limits; a reexamination of Mary Leng’s defenses of mathematical fictionalism through an alternative, anti-realist approach to mathematics; and a look at the reasons that mathematicians select specific problems to pursue. Written by leading scholars in the field, these papers are accessible to not only mathematicians and students of the history and philosophy of mathematics, but also anyone with a general interest in mathematics.

There are three different degrees to which we may allow a systematic theory of the world to embrace the idea of relatedness—supposing realism about non-symmetric relations as a background requirement. (First Degree) There are multiple ways in which a non-symmetric relation may apply to the things it relates—for the binary case, aRb ≠ bRa. (Second Degree) Every such relation has a distinct converse—for every R such that aRb there is another relation R* such that bR*a. (Third Degree) Each one of (...) them applies in an order to the things it relates—with regard to the state that results from R's applying to a and b, either R applies to a first and b second, or it applies to b first and a second. Whereas the first degree is near-indubitable, embracing the second or third generates unwholesome consequences. The second degree embodies a commitment to the existence of a superfluity of distinct converses and states to which such relations give rise. The third degree embodies commitment to recherché facts of the matter about how the states that arise from the application of one non-symmetric relation compare to any other. It is argued that accounts that purport to offer an analysis of the first degree generate unwelcome second or third degree consequences. This speaks in favour of our adopting an account of the application of relations that's not an analysis at all, an account that takes the first degree as primitive. (shrink)

Each world faith tradition has its own distinctive relationship with science, and the science-religion dialogue benefits from a greater awareness of what this relationship is. In this book, members of the International Society for Science and Religion (ISSR) offer international and multi-faith perspectives on how new discoveries in science are met with insights regarding spiritual realities.The essays reflect the conviction that “religion and science each proceed best when they’re pursued in dialogue with each other, and also that our fragmented and (...) divided world would benefit more from a stronger dialogue between science and religion.” In Part One, George F. R. Ellis, John C. Polkinghorne, and Holmes Rolston III, each a Templeton Prize winner, discuss their views on why the science and religion dialogue matters. They are joined in Part Two by distinguished theologians Fraser Watts and Philip Clayton, who place the dialogue in an international context; John Polkinghorne’s inaugural address to the ISSR in 2002 is also included. In Part Three, five members of the ISSR look at the distinctive relationships of their faiths to science: •Carl Feit on Judaism •Munawar Anees on Islam •B.V. Subbarayappa on Hinduism •Trinh Xuan Thuan on Buddhism •Heup Young Kim on Asian Christianity George Ellis, the recently elected second president of ISSR, summarizes the contributions of his colleagues. Ronald Cole-Turner then concludes the book with a discussion of the future of the science and religion dialogue. (shrink)

Do non‐symmetric relations apply to the objects they relate in an order? According to the standard view of relations, the difference between aRb and bRa obtaining, where R is non‐symmetric, corresponds to a difference in the order in which the non‐symmetric relation R applies to a and b. Recently Kit Fine has challenged the standard view in his important paper ‘Neutral Relations’ arguing that non‐symmetric relations are neutral, lacking direction or order. In this paper I argue that Fine cannot account (...) for the application of non‐symmetric relations to their relata; so far from being neutral, these relations are inherently directional. (shrink)

There are important similarities between moral thought and talk and thought and talk about gender: disagreements about gender, like disagreements about morality, seem to be intractable and to outstrip descriptive agreement; and it seems coherent to reject any definition of what it is to be a woman in terms of particular social, biological, or other descriptive features, just as it seems coherent to reject any definition of what it is to be good or right in terms of any set of (...) descriptive properties. These similarities give us reason to investigate the idea that, like moral thought and talk, gender thought and talk is inherently normative. This paper proposes a normative account of gender thought and talk in terms of fitting treatment. On this fitting treatment account, to judge that A is gender G is just to judge that it is fitting to treat A as a G. This account is a descriptive or hermeneutical account of our gender thought and talk rather than an ameliorative account of our gender concepts or a metaphysical account of gender properties in social metaphysics. This paper argues that other descriptive accounts of gender thought and talk face problems that the fitting treatment account overcomes. (shrink)

Epistemic decision theorists aim to justify Bayesian norms by arguing that these norms further the goal of epistemic accuracy—having beliefs that are as close as possible to the truth. The standard defense of Probabilism appeals to accuracy dominance: for every belief state that violates the probability calculus, there is some probabilistic belief state that is more accurate, come what may. The standard defense of Conditionalization, on the other hand, appeals to expected accuracy: before the evidence is in, one should expect (...) to do better by conditionalizing than by following any other rule. We present a new argument for Conditionalization that appeals to accuracy‐dominance, rather than expected accuracy. Our argument suggests that Conditionalization is a rule of coherence: plans that conflict with Conditionalization don't just prescribe bad responses to the evidence; they also give rise to inconsistent attitudes.

The publication of the Fraser Institute's Discrimination, Affirmative Action, and Equal Opportunity offers an occasion to review some of the practical and philosophical issues raised by affirmative action policy. Canadian affirmative action programs derive from the American context, which is here reviewed, but do not have the legal recourse available in the American system. Perhaps as a consequence, most Canadian programs have been carried out by governments acting in their role as employers. The Canadian Union of Public Employees has (...) been especially active in developing union perspectives on affirmative action programs, which do raise special concerns for organized labour. Affirmative action raises several basic questions: the importance of proportionality, merit, compensation and role models in determining who is entitled to opportunities in our society. Differences between the Fraser Institute's attitude about affirmative action and attitudes of other social groups, such as the labour movement, lie in their very different assumptions about what constitutes a free society.

A popular argument is that peer disagreement about controversial moral topics undermines justified moral belief in a way that peer disagreement about non-moral topics does not undermine justified non-moral belief. Call this argument the argument for moral skepticism from peer disagreement. Jason Decker and Daniel Groll have recently made a companions in guilt response to this argument. Decker and Groll argue that if peer disagreement undermines justified moral belief, then peer disagreement undermines much non-moral justified belief; if the argument for (...) moral skepticism from peer disagreement succeeds, then a kind of non-moral skepticism holds too. And we should not hold that the status of such non-moral beliefs are undermined by peer disagreement. In this paper, I shows that Decker and Groll’s companions in guilt argument fails. I then draw out the implications of my argument for the epistemology of disagreement and the epistemology of moral disagreement more generally. For instance, I then argue that peer disagreement about morality does not undermine all justified moral belief but that peer disagreement about morality does preclude most moral beliefs from being justified and constituting knowledge in a way that peer disagreement about non-moral topics does not preclude most non-moral beliefs from being justified and constituting knowledge.

At once historical and philosophical, Michel Foucault used his genealogical method to expose the contingent conditions constituting the institutions, sciences and practices of the present. His analyses of the asylum, clinic, prison and sexuality revealed the historical, political and epistemological forces that make up certain types of subjects, sciences and sites of control. Although noting the originality of his work, a number of early critics questioned the normative framework of Foucault's method. Nancy Fraser argued that Foucault's genealogical method was (...) ‘normatively confused’ as it implied political critique yet claimed to be value-neutral. Jürgen Habermas and Charles Taylor also questioned the normative basis of Foucault's appeals to critique, arguing it was self-refuting as Foucault left no room for the subject to escape power. Although a debate among these scholars was planned for the mid-1980s, Foucault's death in 1984 meant this could not occur. A number of edited volumes sought to fabricate a debate, with defenders of Foucault excavating his published monographs to construct responses to his critics. While the monographs remain the central texts of Foucault's oeuvre, over the past decade his Collège de France lectures have been published and translated into English. This article offers a schematic survey of the influence of the Collège de France lectures in recasting different points in the debates over normativity, critique and resistance. (shrink)

The issue of care work has become a burning issue in western capitalist welfare states because of the greater proportion of women in the workforce and the growth of alternative forms of family arrangement outside of the traditional male breadwinner model. This article addresses equity and welfare states with respect to social entitlements around care. It asks how new theoretical concepts can be applied to understand welfare states and their evolving employment-related family policies, using Nancy Fraser's utopian universal caregiver (...) approach as a model for evaluation. It focuses on carers and evaluates how a modern citizen is expected to be financially self-sufficient and yet also perform care duties at home. The term 'carer-commodification' captures the extent to which the state expects carers to engage in the labour market and how non-carer earners are engaged in care duties. The term 'carer-stratification' incorporates the extent to which the state creates differences between carers. Policies from selective welfare states (Sweden, Germany, Italy, the United Kingdom and the United States) are evaluated speculatively with these tools, and how they fare with equitable social entitlements is illustrated.

In this article, we consider two independently appealing theories—the Growing-Block view and Humean Supervenience—and argue that at least one is false. The Growing-Block view is a theory about the nature of time. It says that past and present things exist, while future things do not, and the passage of time consists in new things coming into existence. Humean Supervenience is a theory about the nature of entities like laws, nomological possibility, counterfactuals, dispositions, causation, and chance. It says that none of (...) these entities are fundamental, since if they were, this would entail the existence of irreducible necessary connections between matters of fact. Instead, these entities supervene on a fundamental, non-nomological ‘Humean mosaic’ of property instances at spacetime points. We will further explain and motivate the Growing-Block view and Humean Supervenience in Sects. 2 and 3, but first, we turn to our master argument. (shrink)

I am interested in extending modal calculi by adding propositional quantifiers, given by the rules for quantifier introduction: provided that p does not occur free in A.

The author's motivation for constructing the calculi of this paper\nis so that time and tense can be "discussed together in the same\nlanguage" (p. 282). Two types of enriched propositional caluli for\ntense logic are considered, both containing ordinary propositional\nvariables for which any proposition may be substituted. One type\nalso contains "clock-propositional" variables, a,b,c, etc., for\nwhich only clock-propositional variables may be substituted and that\ncorrespond to instants or moments in the semantics. The other type\nalso contains "history-propositional" variables, u,v,w, etc., for\nwhich only history-propositional variables may (...) be substituted and\nthat correspond to maximally linearly ordered subsets of instants.\nThis second type is for tense logics in which time is not linear\nand where at any moment there may exist alternative future courses\nof events. Quantifiers are included in both types but only for clock-\nand history-propositional variables. However, these quantifiers are\ngiven an essentially substitutional interpretation. In addition,\nbesides each clock-propositional variable being true at exactly one\ninstant, the semantics requires that for each instant there be at\nleast one clock-propositional variable true at that instant, which\nin effect amounts to having each instant of the model "denoted" in\nthe formalism by some clock-propositional variable. Thus it is not\nsurprising that quantification over clock-propositional variables\nturns out to have a "well behaved first-order semantics" (p. 284).\n{One axiom relating history- with clock-propositions seems to need\nrevision: CKTauTbuAUabUba. Since the clock-propositional variables\nmight be true at the same instant the consequent should include an\nalternative, namely, LCab.} Besides the standard truth-functional\nand tense operators G,H,F,P, the author includes L for "it is\nalways the case that". The model-theoretic earlier-than relation\nordering instants and the semantic truth-at (an instant) relation\nare formalized by Uab and Taα (for a wff α) which\nare defined respectively as LCbPa (whenever the clock-proposition\nb is the case the clock-proposition a was the case) and LCaα\n(α is the case whenever the clock-proposition a is the case).\nBecause the future tense operators are definable in terms of U\nand T and the latter are definable in terms of L and P, the\ndual of H, the author notes that his completeness proofs can be\nrestricted to L and H as primitive and with the future tense\noperators used for other interpretations, especially Prior, A.'s\nindeterminist "it will be the case that", where time is not linear.\nThe author concludes with some rather technical observations showing\nthat "in ordinary tense logics the instants are nonstandard elements\nof the models. This provides", according to the author, "a semantic\npressure to build the instants into tense logic, so that they will\nappear as standard elements in the models" (p. 283). (shrink)

We show that five important elements of the ‘nomological package’— laws, counterfactuals, chances, dispositions, and counterfactuals—needn’t be a problem for the Growing-Block view. We begin with the framework given in Briggs and Forbes (in The real truth about the unreal future. Oxford studies in metaphysics. Oxford University Press, Oxford, 2012 ), and, taking laws as primitive, we show that the Growing-Block view has the resources to provide an account of possibility, and a natural semantics for non-backtracking causal counterfactuals. We show (...) how objective chances might ground a more fine-grained concept of feasibility, and furnished a places in the structure where causation and dispositions might fit. The Growing-Block view, thus understood, provides the resources to explain the close link between modality and tense, so that it predicts modal change as time passes. This account lets us capture not only what the future might hold for us, and also what might have been. (shrink)

Research ethics committees—animal ethics committees for animal-based research and institutional research boards for human subjects—have a key role in research governance, but there has been little study of the factors influencing their effectiveness. The objectives of this study were to examine how the effectiveness of a research ethics committee is influenced by committee composition and dynamics, recruitment of members, workload, participation level and member turnover. As a model, 28 members of AECs at four universities in western Canada were interviewed. Committees (...) were selected to represent variation in the number and type of protocols reviewed, and participants were selected to include different types of committee members. We found that a bias towards institutional or scientific interests may result from a preponderance of institutional and scientist members, an intimidating atmosphere for community members and other minority members, recruitment of community members who are affiliated with the institution and members joining for reasons other than to fulfil the committee mandate. Thoroughness of protocol review may be influenced by heavy workloads, type of review process and lack of full committee participation. These results, together with results from the literature on research ethics committees, suggested potential ways to improve the effectiveness of research ethics committees. (shrink)

Sociological and philosophical analysis of the role of will power upon the moral development of individuals.

This book is an attack on the widespread assumption that the mind has parts and that it is the interaction between these parts which accounts for the irrational behaviour displayed un self- deception and weakness of will.
