Prominent views about representation share a premise: that mathematical communication theory is blind to representational content. Here I challenge that premise by rejecting two common misconceptions: that Claude Shannon said that the meanings of signals are irrelevant for communication theory (he didn't and they aren't), and that since correlational measures can't distinguish representations from natural signs, communication theory can't distinguish them either (the premise is true but the conclusion is false; no valid argument can link them).

The kind of empathy that is communicated through expressions like “I feel your pain” or “I share your sadness” is important, but peculiar. For it seems to require something perplexing and elusive: sharing another’s experience. It’s not clear how this is possible. We each experience the world from our own point of view, which no one else occupies. It’s also unclear exactly why it is so important that we share others' pains. If you are in pain, then why should it (...) matter, and be a good thing, that I am also in the same pain? Our goal in this paper is to address these questions. Specifically, our goal is to clarify how empathy, in the regimented sense of sharing another’s pain, is possible and why it is important. Central to our account is the concept of being acquainted with—that is, directly aware of—pain. When I feel my own pain, and am acquainted with it, I want the pain to stop, and I’m moved—sometimes compelled—to stop it. My acquaintance with the pain is what reveals that it is no good, to be gotten rid of, and to be avoided in the future. Acquaintance also appears to be implicated in our understanding of, and motivation to relieve, others’ pains. When I say “I feel your pain” I express an awareness of your pain, a direct appreciation of its noxious qualities, and, as with my own pain, an understanding of why it ought to be eased. Explaining how empathy is both possible and important therefore involves clarifying the nature of acquaintance: its limits, epistemic role, and motivational significance. What our analysis reveals is that agents have both epistemic and moral reasons to share other people’s pain because pain-sharing is the source of a species of character-building knowledge that we have no other way of accessing except through direct acquaintance with pain.

Creations of the Mind presents sixteen original essays by theorists from a wide variety of disciplines who have a shared interest in the nature of artifacts and their implications for the human mind. All the papers are written specially for this volume, and they cover a broad range of topics concerned with the metaphysics of artifacts, our concepts of artifacts and the categories that they represent, the emergence of an understanding of artifacts in infants' cognitive development, as well as the (...) evolution of artifacts and the use of tools by non-human animals. This volume will be a fascinating resource for philosophers, cognitive scientists, and psychologists, and the starting point for future research in the study of artifacts and their role in human understanding, development, and behaviour.Contributors: John R.

I argue here that Christian ethical responses to Artificial Intelligence (AI) ought to take on, largely, two different approaches. The first considers proximate ethical concerns related to AI. This ethical approach most often considers more immediate personal and socio-political repercussions and the kind of impact that is occurring now or in the very near future. Proximate ethics of this type includes discussion about fairness, accountability, sustainability and transparency. The second concerns ultimate ethics which focuses on the longer-term impact and implications (...) of AI. Examples of this type might include issues of uniqueness, deep societal transformation and inequality, changes to personal character and even the role AI might have in God's ultimate economy of creation and grace. My contention is that the Christian church needs to attend to both approaches to AI and that when it focuses too myopically on one at the expense of the other it often eclipses the entire witness of the church in our technological society.

The notion of domain specificity plays a central role in some of the most important debates in cognitive science. Yet, despite the widespread reliance on domain specificity in recent theorizing in cognitive science, this notion remains elusive. Critics have claimed that the notion of domain specificity can't bear the theoretical weight that has been put on it and that it should be abandoned. Even its most steadfast proponents have highlighted puzzles and tensions that arise once one tries to go beyond (...) an initial intuitive sketch of what domain specificity involves. In this paper, we address these concerns head on by developing an account of what it means for a cognitive mechanism to be domain specific that overcomes the obstacles that have made domain specificity seem so problematic. We then apply this understanding of domain specificity to one of the key debates that it has figured prominently in—the rationalism-empiricism debate concerning the origins of cognitive traits—and introduce several related theoretical notions that work alongside domain specificity in helping to clarify what makes a view more (or less) rationalist. This example illustrates how the notion of domain specificity can, and should, continue to play a central role in ongoing debates in cognitive science. (shrink)

We begin by setting out the posision dubbed 'Fregean descriptivism', that Kripke attributed to Frege. We then set out various descriptivist theses. We proced to argue that Kripke’s interpretation of Frege as a reference-fixing descriptivist stems from his ascription of two other views, each logically weaker than reference-fixing descriptivism itself, to Frege. These are sense descriptivism and the view that sense fixes reference. The meaning descriptivism and the reference-fixing descriptivism of Kripke’s Frege have sense descriptivism as their common, logically weaker, (...) core. Since we do not concur with Kripke’s view that Frege was a sense descriptivist, we do not share his reasons for thinking that Frege was a reference-fixing descriptivist. (shrink)

ABSTRACTAn undemanding claim ϕ sometimes implies, or seems to, a more demanding one ψ. Some have posited, to explain this, a confusion between ϕ and ϕ*, an analogue of ϕ that does not imply ψ. If-thenists take ϕ* to be If ψ then ϕ. Incrementalism is the form of if-thenism that construes If ψ then ϕ as the surplus content of ϕ over ψ. The paper argues that it is the only form of if-thenism that stands a chance of being (...) correct. (shrink)

As practicing clinicians, physicians are expected to uphold the ethical norms of their profession, including fidelity to patients and respect for patients’ self-determination. At the same time, as individuals, physicians are moral agents in their own right and, like their patients, are informed by and committed to diverse cultural, religious, and philosophical traditions and beliefs. In some circumstances, the expectation that physicians will put patients’ needs and preferences first may be in tension with the need to sustain the sense of (...) moral integrity and continuity that grounds a physician’s personal and professional life. This article examines the implications for patients, physicians, and the medical profession when tensions arise between a physician’s professional commitments and his or her deeply held personal moral beliefs. It offers guidance on when a physician’s professional commitments should outweigh personal beliefs as well as when physicians should have freedom to act according to the dictates of conscience while still protecting patients’ interests.

Sam Harris, a previously unknown neuroscientist, single-handedly generated the New Atheism with his best-selling book The End of Faith, which quickly became a huge best-seller following its release in 2004. Harris went on to write several more best-sellers on a range of topics and has become one of the world's most followed podcasters. He is well-known for his controversial positions in many areas, including the unique danger of Islam, the advocacy of atheist spirituality through meditation, the beneficial use of psychedelics, (...) denial of the existence of free will, his belief that science can tell us what's right and wrong, and his extreme alarmism with regard to the future of artificial intelligence. Sam Harris: Critical Responses is a collection of essays criticizing different aspects of Harris's thinking from a range of diverse perspectives--left and right, Christian and atheist, philosophical, psychological, and political. These twenty serious criticisms of Sam Harris, written by experts from diverse political and ideological backgrounds, are often severe while maintaining an approach that is reasonable and respectful. As one noted author commented on Sandra Woien's previous collection, Jordan Peterson: Critical Responses, "Both fans and foes will appreciate this volume." Forward by Stephen R. C. Hicks.

Patients with mental illness, and depression in particular, present clinicians and surrogate decision-makers with complex ethical dilemmas when they refuse life-sustaining non-psychiatric treatment. When treatment rejection is at variance with the beliefs and preferences that could be expected based on their premorbid or “authentic” self, their capacity to make these decisions may be called into question. If capacity cannot be demonstrated, medical decisions fall to surrogates who are usually advised to decide based on a substituted judgment standard or, when that (...) is not possible, best interest. We propose that in cases where the patient meets the widely accepted cognitive criteria for capacity but is making decisions that appear inauthentic, the surrogate may best uphold patient autonomy by following a “restorative representation” model. We see restorative representation as a subset of substituted judgement in which the decision-maker retains responsibility for deciding as the patient would have, but discerns the decision their “truest self” would make, rather than inferring their current wishes, which are directly influenced by illness. Here we present a case in which the patient’s treatment refusal and previously undiagnosed depression led to difficulty determining the patient’s authentic wishes and placed a distressing burden on the surrogate decision-maker. We use this case to examine how clinicians and ethicists might better advise surrogates who find themselves making these clinically and emotionally challenging decisions. (shrink)

How would feminist concerns fare in the debate between Confucian role ethics and virtue ethics? Ann Pang-White sketches the contours of a non-dichotomous, role-based virtue ethics that is illuminated by a Confucian feminist account as one possible answer to this query. By reimagining the virtues of chastity and filiality that are indispensable to Confucian contexts, Pang-White seeks to develop a reading that can be useful in defending feminist values and replacing outdated understandings of gender roles in societies informed by Confucian (...) thought today. In continuing the conversation with her, Stephen Angle asks whether a modernized, relational, role-based virtue ethics can really suffice to respond to feminist concerns. Sarah Mattice proposes that Pang-White center intersectional perspectives on feminism for the latter’s project, while Lily Zhang invites her to analyze how certain ethical conflicts that arise within the framework of Confucian ethics between roles and virtues can be resolved from Pang-White’s perspective. Pang-White’s reply to the panel reiterates different aspects of her relational role-based virtue ethical reading of Confucian feminism to argue that a better appreciation of the situatedness and imperfections of morality is needed to understand the imperfections that come in with it. _ _.

How, if at all, does one's intention to realize an end bear on the justification for taking the means to that end? Theories that allow that intending an end directly provides a reason to take the means are subject to a well-known "bootstrapping" objection. On the other hand, "anti-psychologistic" accounts—which seek to derive instrumental reasons directly from the reasons that support adopting the end itself—have unacceptable implications where an agent faces multiple rationally permissible options. An alternative, predictive, role for intention (...) in means-end reasoning is considered and rejected. A new proposal is then developed, according to which instrumental reasons are not merely reasons to perform an act necessary for a given end, but to perform the act for the sake of that end.

Traditionally, it is believed that God is all-powerful and omnipresent. Given the notion of divine omnipresence, why does it seem like God is absent amidst suffering? This paper presents a philosophical and theological analysis of God’s omnipresence. I hope to show how we may construe a robust and viable doctrine of divine omnipresence amidst suffering. I argue that although God’s presence results in divine action, given that divine action is mostly experienced in a relational, covenantal context, his presence does not (...) always lead to the absence of suffering. Although God is ontologically and maximally omnipresent, he is specially and covenantally present only with those who are open to a relationship with him. His presence with worshippers can be both interventional and noninterventional. In the former, he might remove suffering; in the latter, only inner peace and comfort might be experienced. (shrink)

This study in moral, political, and legal philosophy contends that it is morally impermissible to circumcise male minors without a medical indication (nontherapeutic circumcision). Male minors have a moral anticipatory autonomy right-in-trust not to be circumcised. This right depends on norms of autonomy and bodily integrity. These norms generate three direct non-consequentialist arguments against nontherapeutic circumcision: (1) the loss of nonrenewable functional tissue, (2) genital salience, and (3) limits on a parental right to permanently modify their sons' bodies. An indirect (...) argument holds (4) that if it is morally impermissible to remove the female prepuce (clitoral hood), then it is also morally impermissible to remove the male prepuce (foreskin). Although there is debate across medical cultures, a reasonable understanding supports the claim that nontherapeutic circumcision causes some harms and imposes unwarranted risks on male minors. The overall moral case applies to secular circumcisions and, with some qualifications, to religious circumcisions in Judaism and Islam. Arguments of political philosophy that invoke the freedom of religion, toleration, multiculturalism, and social meaning qualify somewhat, but do not eliminate, the case against circumcising male minors without a medical indication. Nevertheless, the arguments deployed in this study do not warrant legal interference at this time with secular and religious practices of nontherapeutic circumcision. (shrink)

Public health care interventions—regarding vaccination, obesity, and HIV, for example—standardly take the form of information dissemination across a community. But information networks can vary importantly between different ethnic communities, as can levels of trust in information from different sources. We use data from the Greater Pittsburgh Random Household Health Survey to construct models of information networks for White and Black communities--models which reflect the degree of information contact between individuals, with degrees of trust in information from various sources correlated with (...) positions in that social network. With simple assumptions regarding belief change and social reinforcement, we use those modeled networks to build dynamic agent-based models of how information can be expected to flow and how beliefs can be expected to change across each community. With contrasting information from governmental and religious sources, the results show importantly different dynamic patterns of belief polarization within the two communities. (shrink)

Recovering the Soul explores an area of historical philosophy that few if any others have attempted by critically comparing the metaphysical doctrines of Thomas Aquinas and Baruch Spinoza on the identity of mind and body. The central premise is that the hylomorphism of Aquinas's understanding of soul and body has a surprising affinity with Spinoza's own understanding of how human beings are enabled to exist as a single entity that is both mind and body. In the process of making the (...) case that hylomorphism can apply to Spinoza's philosophy as much as Aquinas's, the book carefully exegetes the work of each philosopher and indicates how each is internally consistent within his own system of thought. The hylomorphic reading of Spinoza helps to address some interpretive challenges that his commentators have noted and struggled to harmonize with other aspects of this monist ontology. Beyond the historical and interpretive interests the book addresses, it also makes the case that hylomorphism as a metaphysical theory of human constitution best harmonizes with contemporary studies in the human genome and provides a more comprehensive starting point for the philosophy of mind than reductionism or substance dualism.

In “Is Philosophy Exceptional? A Corpus-Based, Quantitative Study” (2022), Moti Mizrahi and Michael Adam Dickinson use corpus methods to determine the kinds of arguments that turn up in philosophical writing. They use the results to contribute to debates on philosophy’s “specialness” or “exceptionality”. To what extent is philosophy interestingly unlike other knowledge-making disciplines? Specifically, does it deploy different forms of argument than the sciences or other disciplines? -/- These questions are interesting, and Mizrahi and Dickinson’s methodological approach is impressive. Nonetheless, (...) we have concerns about the approach. In this short reply, we argue there are reasons to worry about the accuracy of the results that the authors report and reasons to wonder how their results, even if accurate, shed light on questions about philosophy’s specialness. We end with some thoughts about the strengths and weaknesses of the project and some suggestions for next steps for those interested in moving this project (and others of its ilk) forward. (shrink)

Categorical loudness scaling (CLS) measures provide useful information about an individual’s loudness perception across the dynamic range of hearing. A probability model of CLS categories has previously been described as a multi-category psychometric function (MCPF). In the study, a representative “catalog” of potential listener MCPFs was used in conjunction with maximum-likelihood estimation to derive CLS functions for participants with normal hearing and with hearing loss. The approach of estimating MCPFs for each listener has the potential to improve the accuracy of (...) the CLS measurements, particularly when a relatively low number of data points are available. The present study extends the MCPF approach by using Bayesian inference to select stimulus parameters that are predicted to yield maximum expected information (MEI) during data collection. The accuracy and reliability of the MCPF-MEI approach were compared to the standardized CLS measurement procedure (ISO16832:2006). A non-adaptive, fixed-level, paradigm served as a “gold-standard” for this comparison. The test time required to obtain measurements in the standard procedure is a major barrier to its clinical uptake. Test time was reduced from approximately 15 minutes to approximately 3 minutes with the MEI-adaptive procedure. Results indicated that the test-retest reliability and accuracy of the MCPF-MEI adaptive procedures were similar to the standardized CLS procedure. Computer simulations suggest that the reliability and accuracy of the MEI procedure were limited by intrinsic uncertainty of the listeners represented in the MCPF catalog. In other words, the MCPF provided insufficient predictive power to significantly improve adaptive-tracking efficiency under practical conditions. Concurrent optimization of both the MCPF catalog and the MEI-adaptive procedure have the potential to produce better results. Regardless of the adaptive-tracking method used in the CLS procedure, the MCPF catalog remains clinically useful for enabling maximum-likelihood determination of loudness categories. (shrink)

Sir Leslie Stephen, the founding editor of the Dictionary of National Biography, and a writer on philosophy, ethics, and literature, was educated at Eton, King's College London and Trinity College, Cambridge, where he remained as a fellow and a tutor for a number of years.

During his eleven-year (...) tenure, he wrote two successful books on ethics, including The Science of Ethics in 1892, which was widely adopted as a standard textbook. This two-volume work, which was first published in 1896, brings together the lectures he gave to various ethical societies, mostly in London. In Volume 2, he discusses the ethical issues surrounding a range of topics, including luxury, heredity, crime and punishment, and duty. (shrink)

This article addresses the question of the relevance of brain imaging to legal criteria that are behavioral, that is, that require evaluation of a defendant's actions or mental states. It begins with the legal standard for the admissibility of scientific and technical evidence. Then it considers the relevance of imaging to behavioral legal criteria. The problem is translating mechanistic neuroscience data into the law's folk psychological standards. It uses examples from the criminal law, but the analysis generalizes to behavioral criteria (...) in the civil law. The central question is, “How, precisely, does the proffered scan or data based on scanning answer the specific legal question it supposedly helps answer?” I conclude that, at present, brain imaging has little relevance to behavioral legal criteria. The final section takes note of a rampant disorder, brain overclaim syndrome, and offers a remedy, cognitive jurotherapy. (shrink)

Corporations, through their products and behaviors, exert a strong effect on the wellbeing of populations. Public health practitioners and academics have long recognized the harms associated with some corporations’ products. For example, firearms are associated with approximately 30,000 deaths in the United States each year1 and over 200,000 deaths globally. Motor vehicles are associated with about 40,000 deaths in the United States each year and over 1.2 million deaths globally. Tobacco products kill about 438,000 people each year in the United (...) States5 and about 4.9 million people worldwide. In addition to producing unsafe or harmful products, some corporations behave in ways that negatively impact the public’s health, such as marketing alcohol to youth and other vulnerable populations. Given these observations, one can conclude that it is possible to quantify the public health impact of individual industries, such as firearms, motor vehicles, tobacco, and alcohol. Health professionals can then target these individual industries to prevent or lessen the harms they cause. (shrink)

Throughout the COVID-19 pandemic, the concept of solidarity has been invoked frequently. Much interest has centred around how citizens and communities support one another during times of uncertainty. Yet, empirical research which accounts and understands citizen’s views on pandemic solidarity, or their actual practices has remained limited. Drawing upon the analysis of data from 35 qualitative interviews, this article investigates how residents in England and Scotland enacted, understood, or criticised (the lack of) solidarity during the first national lockdown in the (...) United Kingdom in April 2020—at a time when media celebrated solidarity as being at an all-time high. It finds that although solidarity was practiced by some people, the perceived lack of solidarity was just as pronounced.

This book explores the impact of developments in pharmaceutical medicine in the twentieth century on a Christian ethical evaluation of transhumanism and future 'hi tech' medical enhancement technologies. It suggests that the Christian ethical assessment of proposed future radical transhumanist biomedical technologies should be conducted in the light of responses to past medical advances. Two specific case studies are featured, focusing on the oral contraceptive pill and on Prozac and SSRI antidepressants. Whilst future biomedical technologies may have therapeutic benefits for (...) the relief of disease and contribute to improving human health and welfare, the book considers the implications for society and their acceptability as therapies from a Christian perspective. Stressing the inadequacy of natural law alone, the author proposes an ethical framework for assessing novel biomedical technologies according to the effects on personal autonomy, embodiment and bodily life, and on the Imago Dei.

In earlier publications Jaakko Hintikka has introduced the interrogative model of inquiry and studied some of its applications.1 At its simplest, the interrogative model takes the form of a game between a player known as the Inquirer and a source of information we call Nature. The inquirer is trying to derive a conclusion C from a given set of premises T by standard deductive means augmented by additional information gained from Nature. (We can think of C as a set of (...) formulas related disjunctively to each other.) The inquirer may obtain this additional information by means of questions put to Nature. The answers to these questions, when available, are then added to the premise set T. When a question is answerable but no true answer is available, Nature may respond with a false answer.The deductive steps employed are subject to certain limitations. For instance, if the derivation is being carried out in a Beth-style tableau system, we require that the deductive steps obey the subformula principle.2. (shrink)

In a little over two hundred years, American legal thought moved from premodernism through modernism and into postmodernism. This book charts that intellectual voyage, stressing both the historical contexts in which ideas unfolded and the inherent force of the ideas themselves.Author Stephen M. Feldman first defines "premodernism," "modernism," and "postmodernism," then explains the development of American legal thought through these three intellectual periods. His narrative revolves around two broad, interrelated themes: jurisprudential foundations and the notion of progress. He points (...) out that much of American legal thought has grappled with the problem of identifying the foundations of the American judicial system and judicial decision making. The various ideas of jurisprudential foundations, moreover, are closely tied to shifting notions of progress-the definition of the term, assumptions about the possibility of progress, and hopes about how law might contribute to it.This book's broad historical sweep and its clear explanations of the competing theoretical positions of current legal scholarship make it indispensable to students and scholars of jurisprudence and American legal history.
