A commentary on “Men and Abortion Decisions,” by John Hardwig, in the March‐April 2015 issue.

In three studies, we examined food as an elicitor of nostalgia. Study 1 participants visualised eating either a nostalgic or regularly consumed food. Study 2 participants visualised consuming 12 foods. Study 3 participants consumed 12 flavour samples. Following their food experiences, all participants responded to questions regarding the profile of food-evoked nostalgia (i.e. autobiographical relevance, arousal, familiarity, positive and negative emotions) and several psychological functions (i.e. positive affect, self-esteem, social connectedness, meaning in life). Study 2 and 3 participants also reported (...) their state nostalgia. Results revealed that food is a powerful elicitor of nostalgia. Food-evoked nostalgia has a similar contextual profile to previously examined elicitors, but is a predominantly positive emotional experience. Food-evoked nostalgia served multiple psychological functions and predicted greater state nostalgia. (shrink)

A response to “Can Voice Be Given If No One Is Listening?,” by Chelsea A. Jack.

Thousands of youth suffering from acquired brain injury or other early-life neurological disease live, mature, and learn with only limited communication and interaction with their world. Such cognitively capable children are ideal candidates for brain-computer interfaces. While BCI systems are rapidly evolving, a fundamental gap exists between technological innovators and the patients and families who stand to benefit. Forays into translating BCI systems to children in recent years have revealed that kids can learn to operate simple BCI with proficiency akin (...) to adults. BCI could bring significant boons to the lives of many children with severe physical impairment, supporting their complex physical and social needs. However, children have been neglected in BCI research and a collaborative BCI research community is required to unite and push pediatric BCI development forward. To this end, the pediatric BCI Canada collaborative network was formed, under a unified goal to cooperatively drive forward pediatric BCI innovation and impact. This article reflects on the topics and discussions raised in the foundational BCI-CAN meeting held in Toronto, ON, Canada in November 2019 and suggests the next steps required to see BCI impact the lives of children with severe neurological disease and their families.

The New Evil Demon Problem is supposed to show that straightforward versions of reliabilism are false: reliability is not necessary for justification after all. I argue that it does no such thing. The reliabilist can count a number of beliefs as justified even in demon worlds, others as unjustified but having positive epistemic status nonetheless. The remaining beliefs---primarily perceptual beliefs---are not, on further reflection, intuitively justified after all. The reliabilist is right to count these beliefs as unjustified in demon worlds, (...) and it is a challenge for the internalist to be able to do so as well. (shrink)

It is sometimes said that our age is an age of relativism. For example, Paul Tillich has expressed his “uneasiness about the victory of relativism in all realms of thought and life today.” Karl Popper tells us that “the main philosophical malady of our time is an intellectual and moral relativism, the latter being at least in part based on the former.” What Popper refers to as “intellectual relativism” consists in part in a doctrine about truth which is sometimes expressed (...) as “There is no such thing as absolute truth.” At other times it is expressed by saying “truth is relative.”.

This paper will seek firstly to understand Deleuze’s main challenges to phenomenology, particularly as they are expressed in The Logic of Sense and What is Philosophy?, although reference will also be made to Pure Immanence and Difference and Repetition. We will then turn to a discussion of one of the few passages in which Deleuze directly engages with Merleau-Ponty, which occurs in the chapter on art in What is Philosophy? In this text, he and Guattari offer a critique of what (...) they call the “final avatar” of phenomenology – that is, the “fleshism” that Merleau-Ponty proposes in his unfinished but justly famous work, The Visible and the Invisible. It will be argued that both Deleuze’s basic criticisms of phenomenology, as well as he and Guattari’s problems with the concept of the flesh, do not adequately come to grips with Merleau-Ponty’s later philosophy. Merleau-Ponty is not obviously partisan to what Deleuze finds problematic in this tradition, despite continuing to identify himself as a phenomenologist, and is working within a surprisingly similar framework in certain key respects. In fact, in the more positive part of this paper, we will compare Merleau-Ponty’s notion of flesh, and Deleuze’s equally infamous univocity of being, as a means to consider the broader question of the ways in which the two philosophers consider ontological thought, its meaning and its conditions. It is our belief that through properly understanding both positions, a rapprochement, or at least the foundation for one, can be established between these two important thinkers. (shrink)

The conventional paradigm for developing new treatments for disease mainly involves either the discovery of new drug targets, or finding new, improved drugs for old targets. However, an ion channel found only in invertebrates offers the potential of a completely new paradigm in which an established drug target can be re‐engineered to serve as a new candidate therapeutic agent. The L‐glutamate‐gated chloride channels (GluCls) of invertebrates are absent from vertebrate genomes, offering the opportunity to introduce this exogenous, inhibitory, L‐glutamate receptor (...) into vertebrate neuronal circuits either as a tool with which to study neural networks, or a candidate therapy. Epileptic seizures can involve L‐glutamate‐induced hyper‐excitation and toxicity. Variant GluCls, with their inhibitory responses to L‐glutamate, when engineered into human neurons, might counter the excitotoxic effects of excess L‐glutamate. In reviewing recent studies on model organisms, it appears that this approach might offer a new paradigm for the development of candidate therapeutics for epilepsy. (shrink)

This paper explores the idea that Deleuze’s oeuvre is best understood as a philosophy of the wound, synonymous with a philosophy of the event. Although this wound/scar typology may appear to be a metaphorical conceit, the motif of the wound recurs frequently and perhaps even symptomatically in many of Deleuze’s texts, particularly where he is attempting to delineate some of the most important differences (transcendental, temporal, and ethical) between himself and his phenomenological predecessors. I raise some some potential problems for (...) this trajectory, most of which revolve around Deleuze's use of transcendental philosophy. (shrink)

Goldman, though still a reliabilist, has made some recent concessions to evidentialist epistemologies. I agree that reliabilism is most plausible when it incorporates certain evidentialist elements, but I try to minimize the evidentialist component. I argue that fewer beliefs require evidence than Goldman thinks, that Goldman should construe evidential fit in process reliabilist terms, rather than the way he does, and that this process reliabilist understanding of evidence illuminates such important epistemological concepts as propositional justification, ex ante justification, and defeat.

It is a great pleasure to introduce this collection of papers on the use of introspective evidence in cognitive science. Our task as guest editors has been tremendously stimulating. We have received an outstanding number of contributions, in terms of quantity and quality, from academics across a wide disciplinary span, both from younger researchers and from the most experienced scholars in the field. We therefore had to redraw the plans for this project a number of times. It quickly became clear (...) to us that the collection would expand beyond the scheduled double issue of the Journal of Consciousness Studies. A triple issue was then drafted, but the number of excellent contributions continued to grow. We therefore had to reconsider the publication plans again, and the decision was made to publish an extended collection of papers in discrete instalments. At present substantial progress has been made towards determining the content of a second double issue of the Journal of Consciousness Studies, due summer 2004. A third instalment now appears to be a real possibility. We welcome enquiries from authors interested in submitting to later instalments, especially those offering a novel perspective that is not otherwise represented. However, we do not intend continue this collection indefinitely. In putting together the first major interdisciplinary collection on this topic, we view our task as that of providing a starting point. Sufficient outlets exist to support ongoing debate. (shrink)

In this paper I consider Kierkegaard’s pseudonymous attack on natural theology with respect to how it lines up with Catholic thought on that topic. I argue that Kierkegaard’s recently shown similarities to accounts of basic beliefs raise an interesting question when a Catholic hybrid of basic beliefs and natural theology, which I develop in the paper, is considered. Kierkegaard does not attack what we might call natural reason, or a natural awareness of God’s existence, only natural theology’s demonstrative capabilities, and (...) his reasons for doing the latter, in our current epistemological climate, are shown to be mistaken.

The main claim of this paper is that Andy Clark's most influential argument for ‘the extended mind thesis’ (EM henceforth) fails. Clark's argument for EM assumes that a certain form of common-sense functionalism is true. I argue, contra Clark, that the assumed brand of common-sense functionalism does not imply EM. Clark's argument also relies on an unspoken, undefended and optional assumption about the nature of mental kinds—an assumption denied by the very common-sense functionalists on whom Clark's argument draws. I also (...) critique Mark Sprevak's reductio of Clark's argument. Sprevak contends that Clark's argument does not merely entail EM; it entails an extended mind thesis so strong as to be absurd. He goes on to claim that Clark's argument should properly be viewed as a reductio of the very common-sense functionalism on which it depends. Sprevak's argument shares the flaw that afflicts Clark's argument, or so I claim. (shrink)

What are the limits of physical computation? In his ‘Church’s Thesis and Principles for Mechanisms’, Turing’s student Robin Gandy proved that any machine satisfying four idealised physical ‘principles’ is equivalent to some Turing machine. Gandy’s four principles in effect define a class of computing machines (‘Gandy machines’). Our question is: What is the relationship of this class to the class of all (ideal) physical computing machines? Gandy himself suggests that the relationship is identity. We do not share this view. We (...) will point to interesting examples of (ideal) physical machines that fall outside the class of Gandy machines and compute functions that are not Turing-machine computable. (shrink)

Traditional monist theories of art fail to account for the diversity of objects that intuitively strike many as belonging to the category art. Some today argue that the solution to this problem requires the adoption of some version of pluralism to account for the diversity of art. We examine one recent attempt, which holds that the correct account of art must recognize the plurality of concepts of art. However, we criticize this account of concept pluralism as being unable to offer (...) an explanation of why some concept is an art concept. Instead, many of the disagreements over the definition of art could be reconciled by recognizing that works of art can be valued in a plurality of ways. By recognizing a plurality of values for art, we claim further that the definition of art becomes a non-issue. (shrink)

An examination of the role played by general rules in Hume's positive (nonskeptical) epistemology. General rules for Hume are roughly just general beliefs. The difference between justified and unjustified belief is a matter of the influence of good versus bad general rules, the good general rules being the "extensive" and "constant" ones.

In his 2011 book Justice for Hedgehogs, Ronald Dworkin makes a case for the view that genuine values cannot conflict and, moreover, that they are necessarily mutually supportive. I argue that by prioritizing coherence over the conceptual authenticity of values, Dworkin’s ‘interpretivist’ view risks neglecting what we care about in these values. I first determine Dworkin’s position on the monism/pluralism debate and identify the scope of his argument, arguing that despite his self-declared monism, he is in fact a pluralist, but (...) unusual in denying conflict between plural values. I then set out the structure of his interpretive theory of value relations and present a case of value conflict which I think interpretivism cannot deal with. Following this I argue that there are structural reasons why cases like this are liable to occur and suggest that interpretivism will frequently fail to properly reflect people’s moral commitments because reinterpretation of values has the side effect of excluding important moral commitments from our conceptions of values. While, as Dworkin argues, there are no brute moral facts concerning values, moral psychology constrains the range of acceptable conceptions of values. Given the shortcomings of interpretivism I conclude that we should acknowledge that values may conflict. (shrink)

Karl Popper and Friedrich von Hayek became close friends soon after they first met in the early 1930s. Ever since, they discussed their ideas intensively on many occasions. But even though an analysis of the origins and contents of their ideas and correspondence reveals a number of important and fundamental differences, they rarely criticize each other in their published work. The article analyzes in particular the different ideas they have on the role of reason in society and on rationalism and (...) the roots of these differences. Popper’s “Towards a Rational Theory of Tradition” of 1948 contains a criticism of Hayek’s idea—published, for instance, in “Individualism: True and False” of 1945—that we must accept tradition without trying to change it. An analysis of the differences between the two authors touches on topics such as the possibility of public intervention in society, the role of social science in this, the methodology of social science, and the differences between liberalism and social democracy. The article concludes with some possible explanations for Popper and Hayek downplaying their differences in public. The fact remains that they never resolved the tension between Popper’s critical rationalism and Hayek’s conservative rationalism. (shrink)

Alan Turing, pioneer of computing and WWII codebreaker, is one of the most important and influential thinkers of the twentieth century. In this volume for the first time his key writings are made available to a broad, non-specialist readership. They make fascinating reading both in their own right and for their historic significance: contemporary computational theory, cognitive science, artificial intelligence, and artificial life all spring from this ground-breaking work, which is also rich in philosophical and logical insight.

Most readers of Sartre focus only on the works written at the peak of his influence as a public intellectual in the 1940s, notably "Being and Nothingness". "Jean-Paul Sartre: Key Concepts" aims to reassess Sartre and to introduce readers to the full breadth of his philosophy. Bringing together leading international scholars, the book examines concepts from across Sartre's career, from his initial views on the "inner life" of conscious experience, to his later conceptions of hope as the binding agent for (...) a common humanity. The book will be invaluable to readers looking for a comprehensive assessment of Sartre's thinking - from his early influences to the development of his key concepts, to his legacy. (shrink)

Robert Coles' sentiment characterizes well the moral tenor of medical education today. Indeed, medical educators are frequently “seized by spasms of genuine moral awareness,” as they try to cope with the massive social and economic problems that face medical schools and teaching hospitals. The perception among educators that we currently fail to adequately teach several core aspects of doctoring, including professional values and behavior, constitutes one such spasm. In this case, the proposed remedy has generated considerable enthusiasm, but whether the (...) “core competencies” curriculum will make a difference, or simply “accommodate to the prevailing rhythms of the world we inhabit,” remains to be seen.

Part of a book symposium on Ernest Sosa's Knowing Full Well. An important feature of Sosa's epistemology is his distinction between animal knowledge and reflective knowledge. What exactly is reflective knowledge, and how is it superior to animal knowledge? Here I try to get clearer on what Sosa might mean by reflective knowledge and what epistemic role it is supposed to play.

Concept Pluralism and Concept Eliminativism are two positions recently proposed in the philosophy and the psychology of concepts. Both of these theories are motivated by the view that all current theories of concepts are empirically and methodologically inadequate and hold in common the assumption that for any category that can be represented in thought, a person can possess multiple, distinct concepts of it. In this paper, I will challenge these in light of a third theory, Conceptual Atomism, which addresses and (...) dispels the contentious issues. In particular, I contend that Conceptual Atomism, when properly understood, is empirically adequate and can overcome difficulties that plague Pluralism and Eliminativism. (shrink)

The phrase sacra mensae appears in only a select number of instances from the first century a.d. onwards. This paper seeks to demonstrate that references to sacra mensae are not coincidental, and that they were employed deliberately by authors such as Valerius Maximus and, after him, Quintilian, Tacitus and Seneca, based on an assumed shared understanding of their significance on the part of Roman audiences. Although it appears across a variety of literary works and in a range of contexts, the (...) phrase does not seem to have been used in reference to a specific rite or rites performed at the table. Instead, sacra mensae appears to have been used primarily in a metaphorical sense, designed to epitomize the customs and respect attached to dining in Roman culture. Religion certainly played an important part in creating the aura surrounding the table, which was subject to various rituals and superstitions that were discussed by ancient authors. However, beyond the sphere of religion there was the equally important social emphasis on dining, which enforced notions of conviviality and personal obligation between hosts and guests. Disregard of such traditions came to be identified as a hallmark of tyranny, which provided the writers of the Principate with an opportunity to use the sacra mensae as a powerful literary device against those who failed to respect established customs of hospitality.

This essay examines some of Derrida’s most famous ‘possible-impossible’ aporias, including his discussions of giving, hospitality, forgiveness, and mourning. He argues that the condition of the possibility of such themes is also, and at once, the condition of their impossibility. In order to reveal the shared logic upon which these aporias rely, and also to raise some questions about their persuasive efficacy, it will be argued that of the two polarities evoked by each of his possible-impossible aporias, the ‘impossible’ term (...) of the opposition invariably posits a separation between “two radical singularities”, or in somewhat more controversial terms, between a self and an other. While Derrida emphasises this ‘impossible’ aspect of giving, hospitality, forgiveness, etc., Merleau-Ponty’s abiding emphasis upon the chiasmic intertwining of self and other provides the resources to challenge this emphasis, and even to reverse it. While Merleau-Ponty rarely directly addresses the kind of aporias that concern Derrida, his chiasmic account of embodiment, and his emphasis upon the body-subject’s propensity to seek an equilibrium with its environment, better accounts for the ‘possible’ side of the aporias that Derrida describes. In the process, it will be argued that Merleau-Ponty’s later philosophy also allows for a more politically efficacious idea of responsibility towards the other than the position to which Derrida is tacitly committed.

This chapter challenges the received doxa that the generation of ‘poststructuralist’ philosophers broke decisively with existentialism and rendered it out of date, a mere historical curiosity. Drawing on recent research in the area, it draws some lines of influence, and even argues for some surprising points of commonality, between existentialism and poststructuralism. At least some of the core philosophical ideas of poststructuralists such as Michel Foucault, Jacques Derrida and Gilles Deleuze bear more in common with existentialism than is often supposed. (...) Furthermore, it addresses a common resistance to poststructuralism by committed existentialists by showing that poststructuralism does not abandon concern with responsibility and decision, but in fact develops these themes in ways that are proximate to existentialist concerns. Finally, it argues that some of the needs that some prominent contemporary philosophers find lacking in poststructuralism – in particular, the need for subjective agency – are already met in significant ways in existentialism. These three points serve to throw new light on the contemporary relevance of existentialism, and to open up new directions for research. (shrink)

Frequently cited problems of dualism, as it pertains to the relation of psychological mind to sociocultural world, arise from assumptions of fixed societal and psychological ontologies. If, instead, societal and psychological ontologies are understood to be both emergent and mutable, as a consequence of their dynamic relation, many of the metaphysical and epistemological difficulties encountered by classic psychological-sociocultural dualism are avoided. To this end, an ontological and epistemological position, called societal-psychological constructionism, is presented. The merits of this position relative to (...) postmodern textualist and social constructionist alternatives to classic psychological-sociocultural dualism are discussed. The major advantages of societal-psychological constructionism stem from its metaphysical claim that the psychological derives largely from the sociocultural, but is not reducible to the sociocultural, and in the epistemological implications of this claim. These advantages are particularly significant when contrasted with postmodern textualist and social constructionist accounts that mistakenly conflate the origins of psychological phenomena with psychological experience. 2012 APA, all rights reserved).

Understanding Existentialism provides an accessible introduction to existentialism by examining the major themes in the work of Heidegger, Sartre, Merleau-Ponty and de Beauvoir. Paying particular attention to the key texts, Being and Time, Being and Nothingness, Phenomenology of Perception, The Ethics of Ambiguity and The Second Sex, the book explores the shared concerns and the disagreements between these major thinkers. The fundamental existential themes examined include: freedom; death, finitude and mortality; phenomenological experiences and 'moods', such as anguish, angst, nausea, boredom, (...) and fear; an emphasis upon authenticity and responsibility as well as the denigration of their opposites ; a pessimism concerning the tendency of individuals to become lost in the crowd and even a pessimism about human relations more generally; and a rejection of any external determination of morality or value. Finally, the book assesses the influence of these philosophers on poststructuralism, arguing that existentialism remains an extraordinarily productive school of thought. (shrink)

Following with the discovery of the electron by J. J. Thomson at the end of the nineteenth century a steady elucidation of the structure of the atom occurred over the next 40 years culminating in the discovery of nuclear fission in 1938–1939. The significant steps after the electron discovery were: discovery of the nuclear atom by Rutherford (Philos Mag 6th Ser 21:669–688, 1911 ), the transformation of elements by Rutherford (Philos Mag 37:578–587, 1919 ), discovery of artificial radioactivity by Joliot-Curie (...) and Joliot-Curie (Comptes Rendus Acad Sci Paris 198:254–256, 1934 ), and the discovery of the neutron by Chadwick (Nature 129:312, 1932a , Proc R Soc Ser A 136:692–708, 1932b ; Proc R Soc Lond Ser A 136:744–748, 1932c ). The neutron furnished scientists with a particle able to penetrate atomic nuclei without expenditure of large amounts of energy. From 1934 until 1938–1939 investigations of the reaction between a neutron and uranium were carried out by E. Fermi in Rome, O. Hahn, L. Meitner and F. Strassmann in Berlin and I. Curie and P. Savitch in Paris. Results were interpreted as the formation of transuranic elements. After sorting out complex radio-chemistry and radio-physics O. Hahn and F. Strassmann came to the conclusion, beyond their belief, that the uranium nucleus split into smaller fragments, that is nuclear fission. This was soon followed in 1939 by its theoretical interpretation by L. Mietner and O. Frisch. (shrink)

Revolutions have shaped world politics for the last three hundred years. This volume shows why revolutions occur, how they unfold, and where they created democracies and dictatorships. Jack A. Goldstone presents the history of revolutions from America and France to the collapse of the Soviet Union, 'People Power' revolutions, and the Arab revolts.
