Media exposure influences mental health symptomology in response to salient aversive events, like terrorist attacks, but little has been done to explore the impact of news coverage that varies more subtly in affective content. Here, we utilized an existing data set in which participants self-reported physical symptoms, depressive symptoms, and anxiety symptoms, and completed a potentiated startle task assessing their physiological reactivity to aversive stimuli at three time points (waves) over a 9-month period. Using a computational linguistics approach, we then (...) calculated an average ratio of words with positive vs. negative affective connotations for only articles from news sources to which each participant self-reported being exposed over the prior 2 weeks at each wave of data collection. As hypothesized, individuals exposed to news coverage with more negative affective tone over the prior 2 weeks reported significantly greater physical and depressive symptoms, and had significantly greater physiological reactivity to aversive stimuli.

Progressive supranuclear palsy is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP and 3,247 controls followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the (...) stage 1 SNPs that yielded P ≤ 10-3. We found significant previously unidentified signals associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component. © 2011 Nature America, Inc.

K.J. Devlin has extended Jensen's construction of a model ofZFC andCH without Souslin trees to a model without Kurepa trees either. We modify the construction again to obtain a model with these properties, but in addition, without Kurepa trees inccc-generic extensions. We use a partially defined ◊-sequence, given by a fine structure lemma. We also show that the usual collapse ofκ Mahlo toω 2 will give a model without Kurepa trees not only in the model itself, but also inccc-extensions.

This book is a collection of 18 essays portraying a "humanistic" outlook on several contemporary moral problems, and includes such essayists as Kurt Baier, Carl Rogers, B. F. Skinner, Sidney Hook, Abraham Edel, John Somerville, and Corliss Lamont. Although each was requested first to give his own definition of humanism and then to work out one application of it from his particular field or interest, these directions are not always strictly adhered to. Half of the essays had in fact, already (...) been published in some form in The Humanist. The 5 topical headings of the book show the diversity of fields and interests portrayed: Ethics, Religion and the Meaning of Life; The Good Life; The Individual: Law, Morality and Social Organization; Justice and Society; and Death. Although the essays are of unequal philosophical depth and acumen, this variety may be appealing for some uses of this as a text. However, two of the essays in particular stand out for this reviewer: "Ethics Without Religion" by Kai Nielsen, which perceptively outlines the problematic for as well as against an ethics not rooted in religion, and "The Enforcement of Morals" by Ernest Nagel which aptly analyzes the problem of the relation between the spheres of morality and law taking as a focus the noted Hart-Devlin debate of this issue. The thread which Kurtz believes unites all of these essays is their portrayal of a humanistic viewpoint, a viewpoint which he attempts to summarize in his own 14-page introduction, "What is Humanism?" But defining humanism is not an easy task. One must steer between a strictly negative view which defines it only in relation to what it opposes, and a broader but rather indefinite view of it as some form of man-centered philosophy. Although Kurtz wants to be positive in his own definition, he seems unable to move away from a negative and rhetorical presentation in which theism is simply stated to be incompatible with humanism. Moreover, his outline of a humanistic ethics is somewhat superficial. For example, he seems unaware of the problems involved in holding that ethical values are man’s own "creation" and at the same time are normative and objective. Nevertheless, the book may be of some help as a supplementary text to stimulate undergraduate students in discussion and study of the topics treated therein.—B.A.M. (shrink)

In the grand debate between the paternalist and the libertarian, VanDeVeer sides decidedly with the libertarian. Paternalistic intervention he regards as presumptively wrong, and so the question becomes whether there are countervailing, morally relevant considerations by which paternalistic intervention can be justified. In shifting the burden of justification to the paternalist, VanDeVeer is not being innovative. H. L. A. Hart broke that ground in his Law, Liberty, and Morality in 1963, and Ronald Dworkin used the technique effectively in his 1966 (...) Yale Law Journal essay "Lord Devlin and the Enforcement of Morals." VanDeVeer's contribution, however, is in the explanation he gives for laying the burden of justification on those who would defend paternalistic intervention. Whereas Hart's explanation spoke at the societal or governmental level, VanDeVeer's speaks at the level of the individual person. He rests his argument on the essence of the libertarian position: a principle of overarching individual human autonomy. Consistent with his individualistic focus, he avoids restricting his definitions of paternalistic intervention to activities at the societal or governmental level. VanDeVeer insists that there are moral bounds to paternalistic intervention on the part of private individuals, and it is, perhaps, both the strength and the weakness of the book that he by and large joins conceptually paternalistic intervention by the government and paternalistic intervention by private individuals.

Disney's computer‐animated musical film, Moana tells the tale of Moana, the daughter of Tui, the chief of a Polynesian island, Motunui. Bound by the legendary tradition of her ancestors, Moana is expected to follow her lineage and take over as chief when she grows up. As the authors dig beneath the surface level of the story, they find a metaphorical and philosophical level to Moana's journey. The story of Moana has layers. First, it is literally a tale of Moana's voyage (...) outside beyond the reef so that she can restore the heart of Te Fiti and save the people of Motunui. She closes this tale with a happy ending as she simultaneously lives the life that she freely chooses, becomes the leader of her people (by saving them) as her parents wanted, and honors her tradition insofar as she restores her ancestors' tradition of wayfinding.

This paper constructs a theory according to which an intention is not a mental state but an action at a certain developmental stage. I model intention on organic life, and thus intention stands to action as tadpole stands to frog. I then argue for this theory by showing how it overcomes three problems: intending while merely preparing, not taking any steps, and the action is impossible. The problems vanish when we see that not all actions are mature. Just as some (...) frogs are immature frogs, some actions are immature actions. (shrink)

RÉSUMÉDes travaux récents par Joseph Raz, Niko Kolodny et Sergio Tenenbaum suggèrent qu'il n'existe aucune contrainte normative propre aux intentions. De telles contraintes seraient un mythe. Selon eux, il est possible d'articuler la rationalité des intentions sans postuler que l'intention est un état mental. Je soutiens que nous pouvons aussi comprendre la nature descriptive des intentions sans postuler que l'intention est un état mental. Tout comme l'idée selon laquelle il y aurait des contraintes normatives propres aux intentions, ce postulat est (...) aussi un mythe. L'intention est plutôt une action accompagnée de certaines sous-actions caractéristiques et jouant un rôle de coordination. (shrink)

This paper responds to an argument from Botin which claims that Russellian physicalism is committed to the view that either (i) our phenomenal concepts do not reveal anything essential about phenomenal properties (following Goff, Botin calls this the ‘opaque’ account of phenomenal concepts), or that (ii) phenomenal concepts are capable of revealing at least some of the essence of phenomenal properties—making phenomenal concepts ‘translucent’ if some-but-not-all-revealing or ‘transparent’ if all-revealing—but this entails that phenomenal properties are fundamental, which violates physicalism. I (...) argue that Botin is wrong that Russellian physicalists are committed to the view that physical and phenomenal concepts must have similarly qualitative/phenomenal modes of presentation or contents, since Russellian physicalists assume that we do not possess concepts which specifically refer to non-phenomenal categorical properties. If we were to acquire concepts for non-phenomenal categorical properties, they would need to have categorical contents and modes of presentation, but need not have qualitative/phenomenal contents and modes of presentation. Given this, Russellian physicalists can embrace a translucent account of phenomenal concepts, and hold that our phenomenal concepts more-or-less accurately tell us about certain sorts of non-fundamental properties which are both physical and categorical.

What is the difference between an intended consequence and a foreseen unavoidable consequence? The answer, I argue, turns on the exercise of knowhow knowledge in the process that led to the consequence. I argue for this using a theory according to which acting intentionally is acting as a reason. I show how this gives us a more promising explanation of the difference than the dominant explanations, according to which acting intentionally is acting for a reason.

of (from British Columbia Philosophy Graduate Conference) This paper attempts to argue for an interpretation of Peter Strawson�s account of moral responsibility that successfully eliminates the threat of determinism. The goal is to capture the spirit of Strawson�s view and elucidate that spirit. I do this by emphasizing an aspect of Strawson�s account that others, like Paul Russell, may find insignificant, and then I demonstrate how this aspect is meant to quash the threat of determinism. Specifically, I claim that Strawson (...) wishes us to recognize that certain interpersonal relationships are explanatorily prior to the capacities necessary for morally responsible agency, and this explanatory relationship implies that (at least in our world) the capacities necessary for morally responsible agency could not include freedom from determinism.

This book assesses the existentially relevant consequences of physicalism. It argues that accepting physicalism is the healthiest stance we can take in the face of an account of the self and world which offers no metaphysical assurances. Why should we care about physicalism? On one hand, the view seems to be inconsistent with things that many people find valuable, such as the existence of free will, God, the immortal soul, ultimate purpose, and natural laws like karma. On the other hand, (...) physicalism seems to have positive existential implications, such as supporting the unlimited potential of scientific understanding or the attitude that we need not fear supernatural powers or forces because they don't exist. This book argues that physicalism has several consequences that are of existential import. It begins by outlining the history of physicalism and explaining two popular ways of understanding it: the via negativa approach and the theory-based approach. The rest of Part 1 explores the existential consequences of these two versions of physicalism. Part 2 draws on Nietzsche to construct an argument about what attitude we ought to adopt toward physicalism. It argues that we ought to avoid nihilism and despair even when confronted with a picture of the universe which offers no metaphysical assurances. Finally, Part 3 is dedicated to how well physicalism deals with the hard problem of consciousness, mental causation, and multiple realization. The Hope and Horror of Physicalism will appeal to anyone interested in a contemporary approach to existential philosophy, as well as scholars and advanced students working in philosophy of mind and metaphysics.

Russellian physicalism has the promise of answering all the typical challenges that non-physicalists have issued against standard versions of physicalism, while not giving up physicalism's commitment to the non-existence of fundamental mentality. However, it has been argued that Russellian physicalism must endorse the existence of physically unacceptable protomental properties in order to address these challenges, which would mean giving up on a core physicalist tenet of keeping the fundamental realm untainted by a special relationship to mentality. Against this, I argue (...) that a plausible version of Russellian physicalism can be constructed, which does not posit fundamental properties that are at all protomental in any problematic sense, yet which can explain the existence of subjective experience. This non-protomental Russellian physicalism, which is the only properly-physical version of Russellian physicalism, offers a satisfying solution to the mind-body problem -- including an answer to the conceivability argument -- without sacrificing any of its physicalist credentials.

Physicalism is frequently understood as the thesis that everything depends upon a fundamental physical level. This standard formulation of physicalism has a rarely noted and arguably unacceptable consequence—it makes physicalism come out false in worlds which have no fundamental level, for instance worlds containing things which can infinitely decompose into smaller and smaller parts. If physicalism is false, it should not be for this reason. Thus far, there is only one proposed solution to this problem, and it comes from the (...) so-called via negativa account of physicalism. Via negativa physicalism identifies the physical with the non-mental, such that if everything in the world ultimately depends only on non-mental things, then physicalism is true. To deal with the possibility of worlds without a fundamental level, this account says that physicalism is false in worlds with either a fundamental mental level or an infinite descent of mental levels. Here I argue that there could be a world with an infinite descent of all-mental levels, yet in which physicalism might plausibly be true—thus contradicting the sufficient-for-false condition meant to save physicalism from the threat of infinitely decomposable worlds. This leaves the need for a new dependence-based account of physicalism. (shrink)

Russellian physicalism is a view on the nature of consciousness which promises to satisfy the demands of both traditional physicalists and non-physicalists. It does so by identifying subjective experience with physically acceptable categorical properties underlying structural and dispositional properties described by science. Though promising, the view faces at least two serious challenges: (i) it has been argued that science deals in both categorical and non-categorical properties, which would undercut the motivation behind Russellian physicalism, and (ii) it has been argued that (...) only nonphysicalist Russellian views—like panpsychism—are useful when it comes to explaining consciousness. I address these criticisms, arguing that there is no viable reason for maintaining that science deals in categorical properties of the sort which a Russellian physicalist is interested in, and that features of fully-physical categorical properties can be described which provide useful explanations for various essential features of subjective experience. These projects are connected: it turns out that when the explanatory relevance of Russellian physicalism is explained in detail, constraints are put the sort of categorical properties that Russellian physicalists can say are left out of science. Specifically, Russellian physicalists are forced to subscribe to the view that science leaves out any categorical properties whatsoever, as opposed to the view that some scientifically scrutable properties are categorical, but not the ones which Russellian physicalists are interested in. I hope that by addressing these criticisms of Russellian physicalism, and drawing logical connections between the responses, further appeal is added to a promising, but so far relatively unexplored, view.

The New Evil Demon problem has been hotly debated since the case was introduced in the early 1980’s (e.g. Lehrer and Cohen 1983; Cohen 1984), and there seems to be recent increased interest in the topic. In a forthcoming collection of papers on the New Evil Demon problem (Dutant and Dorsch, forthcoming), at least two of the papers, both by prominent epistemologists, attempt to resist the problem by appealing to the distinction between justification and excuses. My primary aim here is (...) to critically evaluate this new excuse maneuver as a response to the New Evil Demon problem. -/- Their response attempts to give us reason to reject the idea that victims of the New Evil Demon have justification for believing as they do. I shall argue that this approach is ultimately unsuccessful, however much of value can be learned from these attempts. In particular, progress in the debate can be made by following those who advance the excuse maneuver and make explicit the connection between epistemic justification and epistemic norms. By doing so, the questions being debated are clarified, as is the methodology being used to attempt to answer them. (shrink)

In 1962, the publication of Thomas Kuhn’s Structure ‘revolutionized’ the way one conducts philosophical and historical studies of science. Through the introduction of both memorable and controversial notions, such as paradigms, scientific revolutions, and incommensurability, Kuhn argued against the traditionally accepted notion of scientific change as a progression towards the truth about nature, and instead substituted the idea that science is a puzzle solving activity, operating under paradigms, which become discarded after it fails to respond accordingly to anomalous challenges and (...) a rival paradigm. Kuhn’s Structure has sold over 1.4 million copies and the Times Literary Supplement named it one of the “Hundred Most Influential Books since the Second World War.” Now, fifty years after this groundbreaking work was published, this volume offers a timely reappraisal of the legacy of Kuhn’s book and an investigation into what Structure offers philosophical, historical, and sociological studies of science in the future.

Russellian physicalism is a promising answer to the mind–body problem which attempts to satisfy the motivating epistemic and metaphysical concerns of non-physicalists with regards to consciousness, while also maintaining a physicalist commitment to the non-existence of fundamental mentality. Chan (_Philosophical Studies, 178_:2043–62, 2021) has recently described a challenge to Russellian physicalism he deems the ‘difference-maker problem’, which is a Russellian-physicalism-specific version of the more well-known ‘combination problem’ for Russellian monism generally. The problem is to determine how a relatively small set (...) of fundamental categorical property types can ground the large variety of phenomenal properties that exist. To answer this problem, a Russellian physicalist can say that there is strong emergence from fundamental categorical properties to phenomenal properties, or she can say that there is only weak emergence from fundamental categorical properties to phenomenal properties. Chan argues that neither of these routes are viable for Russellian physicalism. This paper constitutes a response to Chan, arguing that Russellian physicalists can embrace either weak or strong emergence to explain phenomenal variety. (shrink)

Regardless of whatever else physicalism requires, nearly all philosophers agree that physicalism cannot be true in a world which contains fundamental mentality. I challenge this widely held attitude, and describe a world which is plausibly all-physical, yet which may contain fundamental mentality. This is a world in which priority monism is true—which is the view that the whole of the cosmos is fundamental, with dependence relations directed from the whole to the parts—and which contains only a single mental system, like (...) a brain or computer. Because some properties of the whole are fundamental under priority monism, it follows that that the mental properties of a cosmos-encompassing brain or computer system may be fundamental in a priority monist world. Yet such a world need not contain anything physically unacceptable: the mental properties of the cosmos-encompassing brain or computer can be characterized in a physicalism-friendly functionalist or identity-theoretic way. Thus, as I see it, physicalism need not be false in such a world. This constitutes a challenge to those who hold the view that physicalism is inconsistent with the existence of fundamental mentality.

There are various equivalent formulations of the Church-Turing thesis. A common one is that every effective computation can be carried out by a Turing machine. The Church-Turing thesis is often misunderstood, particularly in recent writing in the philosophy of mind.

This talk was given Monday 13 May 2002 at Monash University in Melbourne, Australia, and previously to summer visitors at the IBM Watson Research Center in 2001. There are no section titles; the displayed material is what I wrote on the whiteboard as I spoke.

In his essay “Afterwords”, Kuhn describes his “double goal” as To justify that science achieves knowledge of nature, and at the same time, To show that science neither achieves, nor should aim towards achieving, truth. I hold that Kuhn’s denial of truth helps to bring out a tension between the two goals of his enterprise: Kuhn cannot both maintain that science achieves knowledge of nature and dismiss the notion of truth altogether from his philosophy of science. The same arguments that (...) attack truth will ultimately damage the quest for knowledge. In this chapter, I intend explore this problem—which I will call the problem of inconsistency—and ultimately provide a defense on behalf of Kuhn. I argue that Kuhn can achieve both of his goals, and so remain consistent, by reevaluating the notion of truth in his philosophy of science. Here, I introduce an alternative correspondence theory of truth, which I call the phenomenal-world correspondence theory of truth. I will argue that Kuhn’s philosophy of science will remain consistent with this alternative view of correspondence. I believe that this notion of truth not only succeeds in defending Kuhn’s enterprise from the problem of inconsistency, but is also a kind of truth that Kuhn can accept into his philosophical enterprise despite his rejection of the traditional correspondence theory.

Recent years have seen a growing acknowledgement within the mathematical community that mathematics is cognitively/socially constructed. Yet to anyone doing mathematics, it seems totally objective. The sensation in pursuing mathematical research is of discovering prior (eternal) truths about an external (abstract) world. Although the community can and does decide which topics to pursue and which axioms to adopt, neither an individual mathematician nor the entire community can choose whether a particular mathematical statement is true or false, based on the given (...) axioms. Moreover, all the evidence suggests that all practitioners work with the same ontology. (My number 7 is exactly the same as yours.) How can we reconcile the notion that people construct mathematics, with this apparent choice-free, predetermined objectivity? I believe the answer is to be found by examining what mathematical thinking is (as a mental activity) and the way the human brain acquired the capacity for mathematical thinking. (shrink)

In higher education, interdisciplinarity involves the design of subjects that offer the opportunity to experience ‘different ways of knowing’ from students’ core or preferred disciplines. Such an education is increasingly important in a global knowledge economy. Many universities have begun to introduce interdisciplinary studies or subjects to meet this perceived need. This chapter explores some of the issues inherent in moves towards interdisciplinary higher education. Definitional issues associated with the term ‘academic discipline’, as well as other terms, including ‘multidisciplinary’, ‘cross-disciplinary’, (...) ‘pluridisciplinarity’, ‘transdisciplinarity’ and ‘interdisciplinary’ are examined. A new nomenclature is introduced to assist in clarifying the subtle distinctions between the various positions. The chapter also outlines some of the pedagogical and epistemological considerations which are involved in any move from a conventional form of educational delivery to an interdisciplinary higher education, and recommends caution in any implementation of an interdisciplinary curriculum.

Jaegwon Kim maintains that his ‘exclusion argument’ forces us to accept reductive physicalism, which identifies mental and other high-level properties of the world with lower-level properties, over nonreductive physicalism, which avoids such identifications. According to Kim, the exclusion argument shows that any nonreductive view leads to either epiphenomenalism or unacceptable overdetermination of physical effects by physical causes. However, a popular nonreductive physicalist approach called ‘compatibilism’ aims to show that physicalism need not collapse high-level properties into lower-level physical. Compatibilism attempts to (...) block the exclusion argument by attending to the tight modal relationship between higher and lower properties required by nonreductive physicalism. Unfortunately, a similarly tight modal relationship will be embraced by any dualists who hold that natural laws are metaphysically necessary. Despite its increasingly widespread popularity among nonreductive physicalists, it thus seems that the compatibilist’s proposed solution cannot be upheld without removing the barriers to dualists of this sort.

In [2], Prikry showed that if κ is a weakly inaccessible cardinal which carries a Rowbottom filter, then there is a Boolean extension of V (the universe), having the same cardinals as V, in which cf(κ) = ω.
