The dominant approach to analyzing the meaning of natural language sentences that express mathematical knowl- edge relies on a referential, formal semantics. Below, I discuss an argument against this approach and in favour of an internalist, conceptual, intensional alternative. The proposed shift in analytic method offers several benefits, including a novel perspective on what is required to track mathematical content, and hence on the Benacerraf dilemma. The new perspective also promises to facilitate discussion between philosophers of mathematics and cognitive scientists (...) working on topics of common interest. (shrink)

One of the important challenges in the philosophy of mathematics is to account for the semantics of sentences that express mathematical propositions while simultaneously explaining our access to their contents. This is Benacerraf’s Dilemma. In this dissertation, I argue that cognitive science furnishes new tools by means of which we can make progress on this problem. The foundation of the solution, I argue, must be an ontologically realist, albeit non-platonist, conception of mathematical reality. The semantic portion of the problem can (...) be addressed by accepting a Chomskyan conception of natural languages and a matching internalist, mentalist and nativist view of semantics. A helpful perspective on the epistemic aspect of the puzzle can be gained by translating Kurt G ̈odel’s neo-Kantian conception of the nature of mathematics and its objects into modern, cognitive terms.

Psychologism is the attempt to account for the necessary truths of mathematics in terms of contingent psychological facts. It is widely regarded as a fallacy. Jackendoff's view of reference and truth entails psychologism. Therefore, he needs to either provide a defense of the doctrine, or show that the charge doesn't apply.

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

We introduce a family of rules for adjusting one's credences in response to learning the credences of others. These rules have a number of desirable features. 1. They yield the posterior credences that would result from updating by standard Bayesian conditionalization on one's peers' reported credences if one's likelihood function takes a particular simple form. 2. In the simplest form, they are symmetric among the agents in the group. 3. They map neatly onto the familiar Condorcet voting results. 4. They (...) preserve shared agreement about independence in a wide range of cases. 5. They commute with conditionalization and with multiple peer updates. Importantly, these rules have a surprising property that we call synergy - peer testimony of credences can provide mutually supporting evidence raising an individual's credence higher than any peer's initial prior report. At first, this may seem to be a strike against them. We argue, however, that synergy is actually a desirable feature and the failure of other updating rules to yield synergy is a strike against them.

Personal relationships matter. Traditional Consequentialism, given its exclusive focus on agent-neutral goodness, struggles to account for this fact. A recent variant of the theory—one incorporating agent-relativity—is thought to succeed where its traditional counterpart fails. Yet, to secure this advantage, the view must take on certain normative and evaluative commitments concerning personal relationships. As a result, the theory permits cases in which agents do as they ought, yet later ought to prefer that they had done otherwise. That a theory allows such (...) cases is a serious defect. We thus conclude that, in terms of how the theories handle personal relationships, agent-relative consequentialism fairs no better than its traditional counterpart. (shrink)

Special science generalizations admit of exceptions. Among the class of non-exceptionless special science generalizations, I distinguish minutis rectis generalizations from the more familiar category of ceteris paribus generalizations. I argue that the challenges involved in showing that mr generalizations can play the law role are underappreciated, and quite different from those involved in showing that cp generalizations can do so. I outline a strategy for meeting the challenges posed by mr generalizations.

This paper presents the results of an experiment designed to test for nationality bias among members of the Brazilian philosophical community. Faculty members and postgraduate students from philosophy departments at seven Brazilian universities evaluated texts attributed to authors of European and Latin American nationalities. Results showed a clear preference for French nationality over Brazilian. They were inconclusive, however, when contrasting other Latin American nationalities with European nationalities, which likely relates to the academic background of the participants. These overall results support (...) the claim that Brazilian academic philosophers are highly critical of Brazilians who produce theories of their own. The paper calls on philosophers to carefully consider the ways in which Eurocentrism impacts their very ability to reason. (shrink)

As the suspect interview is one of the key elements of a police investigation, it has received a great deal of merited attention from the scientific community. However, suspect interviews in child sexual abuse investigations is an understudied research area. In the present mixed-methods study, we examine Swedish and Norwegian police interviewers' self-reported goals, tactics, and emotional experiences when conducting interviews with suspected CSA offenders. The quantitative analyses found associations between the interviewers' self-reported goals, tactics, and emotions during these types (...) of suspect interviews. Interviewers who reported experiencing more negative emotions were more likely to employ confrontational tactics. Specifically, anger was positively associated with the goal of obtaining a confession and with aggressive tactics like raising one's voice and emphasizing the seriousness of the crime. Frustration and disgust displayed similar patterns. Somewhat contrasting these quantitative results, the thematic analysis identified a strong consensus that emotions should not and do not affect the police interviewers' work. Furthermore, the police interviewers described a range of strategies for managing emotions during the interview and for processing their emotional reactions afterwards. The present findings highlight the relevance of emotional processes in CSA suspect interviews and provide an initial exploration of the potentially complex relationship between the goals, tactics, and emotional experiences of police interviewers who question CSA suspects.

A dogma of contemporary normative theorizing holds that some reasons are distinctively moral while others are not. Call this view Reasons Pluralism. This essay looks at four approaches to vindicating the apparent distinction between moral and non-moral reasons. In the end, however, all are found wanting. Though not dispositive, the failure of these approaches supplies strong evidence that the dogma of Reasons Pluralism is ill-founded.

Choice overload is the phenomenon that increasing the number of options in an assortment makes choosing between options more difficult, sometimes leading to avoidance of making a choice. In this pre-registered online experiment, choice overload was tested in a charitable behavior context, where participants faced a monetary donation choice. Charity organization assortment size was varied between groups, ranging between 2 and 80 options. The results indicate that there were no meaningful differences in donation likelihood between the 16 organization assortment sizes, (...) neither for individuals with high preference certainty nor for individuals with uncertain preferences among charitable causes. Having more charitable organizations to choose from did not affect donation behavior. (shrink)

Appropriate concerns about cost and unequal access to healthcare have resulted in the creation of powerful managed networks seeking to share the risks of high healthcare costs among plans, providers, and patients. Much to their credit, these managed networks have slowed the rise in healthcare spending by as much as 44% in markets with high HMO penetration. However, whether these savings will materially improve access and quality remains to be seen.

Felix Pinkert has proposed a solution to the no-difference problem for AC. He argues that AC should be supplemented with a requirement that agents’ optimal acts be modally robust. We disagree.

This book challenges the common view that Michael Oakeshott was mainly important as a political philosopher by offering the first comprehensive study of his ideas on history. It argues that Oakeshott's writings on the philosophy of history mark him out as the most successful of the philosophers who attempted to establish historical study as an autonomous form of thought during the twentieth century. It also contends that his work on the history of political thought is best seen in the context (...) of debates over the origins of the liberal state. For the first time, extensive use has been made of unpublished material in the collection of Oakeshott's papers at the LSE, resulting in an intellectual biography that should be of interest both to first-time students and those already familiar with his published works.

Jeremy Bentham, the philosopher and reformer, was at the height of his fame and influence in the 1820s. The 301 letters in this volume, many of which are previously unpublished, contain correspondence with international leaders such as Simón Bolívar, the 'Liberator', and Bernardino Rivadavia of Buenos Aires, British statesmen such as Robert Peel and Henry Brougham, and leading intellectuals such as John Stuart Mill and Sarah Austin.

Wrongdoing is inescapable. We all do wrong and are wronged; and in response we often blame one another. But if blame is a defining feature of our social lives, so is ceasing to blame. We might excuse, justify, or forgive an offender; or simply let the offence go. Each mode of ceasing to blame is a social practice and each has characteristic norms that influence when and how we do it, as well as how it’s received. We argue that how (...) we relinquish blame, and how effective we are, depends on many circumstances only partially within our control. Like any norm-governed practice, one can do it well or poorly, appropriately or inappropriately, successfully or unsuccessfully. To successfully participate in a practice, one’s action must be done for the right reasons and secure uptake. We argue that social and material circumstances can compromise one’s ability to effectively cease to blame in the manner one prefers. But if one can fail, then one can lack access to particular ceasing to blame practices if one is regularly prevented from effectively relinquishing blame. However, uncooperative social and material circumstances do not only arise by chance. Our central argument is that circumstances of oppression can systematically compromise one’s ability and opportunities to effectively perform a variety of ceasing to blame practices. This deprivation is an insidious facet of oppression that is neglected both in theories of oppression and of forgiveness but which has significant implications for how we understand the power and purpose of forgiveness.

Leon Goldstein’s critical philosophy of history has suffered a relative lack of attention, but it is the outcome of an unusual story. He reached conclusions about the autonomy of the discipline of history similar to those of R. G. Collingwood and Michael Oakeshott, but he did so from within the Anglo-American analytic style of philosophy that had little tradition of discussing such matters. Initially, Goldstein attempted to apply a positivistic epistemology derived from Hempel’s philosophy of natural science to historical knowledge, (...) but gradually formulated an anti-realistic epistemology that firmly distinguished historical knowledge of the past not only from the scientific perspective but also from fictional and common-sense attitudes to the past. Among his achievements were theories of the distinctive nature of historical evidence and historical propositions, of the constructed character of historical events, and of the relationship between historical research and contemporary culture. Taken together, his ideas merit inclusion among the most important twentieth-century contributions to the problem of historical knowledge. (shrink)

The papers in this special issue make important contributions to a longstanding debate about how we should conceive of and explain mental phenomena. In other words, they make a case about the best philosophical paradigm for cognitive science. The two main competing approaches, hotly debated for several decades, are representationalism and enactivism. However, recent developments in disciplines such as machine learning and computational neuroscience have fostered a proliferation of intermediate approaches, leading to the emergence of completely new positions, in particular (...) the Predictive Processing approach. Here, we will consider the different approaches discussed in this volume. (shrink)

This book is particularly appropriate for graduate seminars or upper division courses in philosophy of mind, and for metaphysics or introductory philosophy ...

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error (...) computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)

Psychotherapy with the use of psychedelic substances, including psilocybin, lysergic acid diethylamide (LSD), ketamine, and 3,4-methylenedioxymethamphetamine (MDMA), has demonstrated promise in treatment of post-traumatic stress disorder (PTSD), anxiety, addiction, and treatment-resistant depression. Psychedelic-assisted psychotherapy (PP) represents a unique psychopharmacological model that leverages the profound effects of the psychedelic experience. That experience is characterized by strong dependency on two key factors: participant mindset and the therapeutic environment. As such, therapeutic models that utilize psychedelics reflect the need for careful design that promotes (...) an open, flexible, trusting mindset and a supportive setting. To meet this need, the PP model is increasingly supplemented by auxiliary methods, including meditation, relaxation, visualization or spiritual practices. We suggest virtual reality (VR) as a full-spectrum tool able to capitalize on and catalyze the innately therapeutic aspects of the psychedelic experience, such as detachment from familiar reality, alteration of self-experience, augmentation of sensory perception and induction of mystical-type experiences. This is facilitated by VR’s evidenced capacity to: aid relaxation and reduce anxiety; buffer from external stimuli; promote a mindful presence; train the mind to achieve altered states of consciousness (ASC); evoke mystical states; enhance therapeutic alliance and encourage self-efficacy. While these unique VR features appear promising, VR’s potential role in PP remains speculative due to lack of empirical evidence on the combined use of VR and PP. Given the increased commercial interest in this synergy there is an urgent need to evaluate this approach. We suggest specific VR models and their role within PP protocols to inspire future direction in scientific research, and provide a list of potential disadvantages, side effects and limitations that need to be carefully considered. These include sensory overstimulation, cyber-sickness, triggering memories of past traumatic events as well as distracting from the inner experience or strongly influencing its contents. A balanced, evidence-based approach may provide continuity across all phases of treatment, support transition into and out of an ASC, deepen acute ASC experiences including mystical states and enrich the psychotherapeutic process of integration. We conclude that the potential application of VR in modulating psychedelic-assisted psychotherapy demands further exploration and an evidence-based approach to both design and implementation.

The concept of civilisation is a controversial one because it is unavoidably normative in its implications. Its historical associations with the effort of Western imperialism to impose substantive conditions of life have made it difficult for contemporary liberalism to find a definition of “civilization” that can be reconciled with progressive discourse that seeks to avoid exclusions of various kinds. But because we lack a way of identifying what is peculiar to the relationship of civilisation that avoids the problem of domination, (...) it has tended to be conflated with other ideas. Taking Samuel Huntington's idea of a “Clash of Civilisations” as a starting point, this article argues that we suffer from a widespread confusion of civilisation with “culture,” and that we also confuse it with other ideas including modernity and technological development. Drawing on Thomas Hobbes, the essay proposes an alternative definition of civilisation as the existence of limits on how we may treat others. (shrink)

Asexuality is overlooked in the philosophical literature and in wider society. Such neglect produces incomplete or inaccurate accounts of romantic life and harms asexual people. We develop an account of asexuality to redress this neglect and enrich discussion of romantic life. Asexual experiences are diverse. Some asexual people have sex; some have romantic relationships in the absence of sex. We accept the common definition of asexuality as the absence of sexual attraction and explain how sexual attraction and sexual desire differ (...) by giving an affordance-like account of sexual attraction. Armed with that distinction, we show that asexuality is clearly different from celibacy or disorders of desire and that some existing philosophical theories of sexual desire struggle to accommodate asexual sexuality. We then build on asexual testimony about the diversity of non-sexual attractions to answer two common objections levelled at asexual romance: that romantic relationships require sexual attraction or that sex in the absence of sexual attraction is insufficiently focused on someone as an individual. Finally, we describe some of the ways asexuality has been erased or denigrated in society, and the specific injustices and harms that result. (shrink)

Background Ethical and scientific principles require that clinical trials address an important question and have the resources needed to complete the study. However, there are no clear standards for review that would ensure that these principles are upheld.Methods We conducted semi-structured interviews with a convenience sample of nineteen experts in clinical trial design, conduct, and/or oversight to elucidate current practice and identify areas of need with respect to ensuring the scientific value and feasibility of clinical trials prior to initiation and (...) while ongoing. We used a priori and grounded theory to analyze the data and constant comparative method to induce higher order themes.Results Interviewees perceived determination of scientific value as the responsibility of the investigator and, secondarily, other parties who review or oversee research. Interviewees reported that ongoing trials are rarely reevaluated due to emerging evidence from external sources, evaluation is complex, and there would be value in the development of standards for monitoring and evaluating evidence systematically. Investigators, IRBs, and/or data monitoring committees (DMCs) could undertake these responsibilities. Feasibility assessments are performed but are typically inadequate; potential solutions are unclear.Conclusions There are three domains where current approaches are suboptimal and in which further guidance is needed. First, who has the responsibility for conducting scientific review, whether it be the investigator, IRB, and/or DMC is often unclear. Second, the standards for scientific review (e.g., appropriate search terms, data sources, and analytic plan) should be defined. Third, guidance is needed on the evaluation of ongoing studies in light of potentially new and evolving evidence, with particular reference to evidence from outside the trial itself. (shrink)

This twelfth volume of Correspondence contains authoritative and fully annotated texts of all known letters sent both to and from Bentham between July 1824 and June 1828. The 301 letters, most of which have never before been published, have been collected from archives, public and private, in Britain, the United States of America, Switzerland, France, Japan, and elsewhere, as well as from the major collections of Bentham Papers at University College London Library and the British Library.In mid-1824 Bentham was still (...) preoccupied with the Greek struggle for independence against Turkey, though his active involvement waned as he became disenchanted with the behaviour of the deputies sent to London by the Greek National Assembly. His international reputation was reflected in his continuing contact with Simón Bolívar and Bernardino Rivadavia in South America, and with John Quincy Adams, John Neal, Henry Wheaton, and others in the United States, and his forging of new contacts in Guatemala, India, and Egypt. In the autumn of 1825 he visited France, where he stayed with Jean Baptiste Say and La Fayette, and was fêted by the French liberals.Bentham made considerable progress drafting material for his pannomion, or complete code of laws, and in particular for his Constitutional and Procedure Codes, while John Stuart Mill edited the massive Rationale of Judicial Evidence. Bentham became increasingly active in the cause of law reform, and exchanged a series of letters on the subject with Robert Peel, the Home Secretary, and Henry Brougham. He maintained his friendships with John and Sarah Austin, George and Harriet Grote, James and John Stuart Mill, John Bowring, Joseph Hume, Francis Burdett, Francis Place, and Joseph Parkes, re-established contact with the third Marquis of Lansdowne, son of his old friend the first Marquis, and made new acquaintances in James Humphreys, Sutton Sharpe, and Albany Fonblanque.

SummaryThe term ‘category mistake’ began to turn up regularly in public discourse in the 1990s as a general term to describe a confusion between different fields of thought with serious practical consequences. But it began its career in philosophy, introduced by Gilbert Ryle in The Concept of Mind in 1949 to attack Cartesian dualism and assert a monistic solution to the so-called mind-body problem. This paper traces the stages by which it came into general usage, arguing that while by the (...) later 1960s it had generally been rejected by philosophers, it was saved from disappearance by its migration into fields such as psychology and theology. From there, it moved into critical theory and then into international relations. Its entry into these latter areas first made plain its potential in political argument. Eventually, multiple meanings of the term came to coexist with one another, with the practical and rhetorical usage supplementing rather than replacing its original philosophical sense. (shrink)
