Technical results about the time dependence of eigenvectors of reduced density operators are considered, and the relevance of these results is discussed for modal interpretations of quantum mechanics which take the corresponding eigenprojections to represent definite properties. Continuous eigenvectors can be found if degeneracies are avoided. We show that, in finite dimensions, the space of degenerate operators has co-dimension 3 in the space of all reduced operators, suggesting that continuous eigenvectors almost surely exist. In any dimension, even when degeneracies are (...) hit, we find conditions under which a theorem due to Rellich can provide continuous eigenvectors. We use this result to formulate an extended version of the modal interpretation. We also discuss eigenvector instability which we argue poses a serious problem for the modal interpretation, even in our extended version. Many examples are given to illustrate the mathematics.

The correspondence theory of truth is often thought to be supported by the intuition that if a proposition (sentence, belief) is true, then something makes it true. I argue that this appearance is illusory and is sustained only by a conflation of two distinct notions of truthmaking, existential and non-existential. Once the conflation is exposed, I maintain, deflationism is seen to be adequate for accommodating truthmaking intuitions.

Daniel Dennett is one of the most influential thinkers at the interface between philosophy and science. This book is the first comprehensive examination of Dennett ’s ideas on the nature of thought, consciousness, free will, and the significance of Darwinism. A highly original introduction to contemporary thinking about the relationship between mind and science. This is the first comprehensive examination of Dennett ’s ideas on the nature of thought, consciousness, free will, and the significance of Darwinism. Examines Dennett ’s unique (...) response to the question of when and how science should affect the conception that we have of ourselves. Casts new light on specific controversies: Could robots ever think, feel, and enjoy freedom? Does Dennett really explain consciousness? Are mental states real or merely ‘useful fictions’? Do we have free will? Is the self a ‘centre of narrative gravity’? (shrink)

Brings together and interprets previously hard-to-find texts, new translations and passages detailing the interplay between philosophy and psychopathology.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.1 (2004) 35-41 [Access article in PDF] The Rationality of Psychosis and Understanding the Deluded Matthew R. Broome Campbell's important and influential paper (Campbell 2001) has framed the debate that Bayne and Pacherie (2004) most explicitly, and Klee (2004) and Georgaca (2004) more implicitly, engage in. Campbell has offered two broad ways of thinking about explanations of delusions—the empirical and the rational. He offers (...) some criticism of the former and an endorsement of the latter. Campbell uses examples from clinical psychopathology to illustrate his argument and Bayne and Pacherie in turn employ these. Campbell discusses the eponymously named delusions of Capgras and Cotard—the former a subtype of delusional misidentification and the latter a delusion whose content is colored predominantly with nihilistic and possibly hypochondriacal themes. Campbell, Bayne and Pacherie, and Klee discuss the empirical data in relation to such delusions and as an aid to discussing the empirical model more generally. It does seem a little unfortunate that these delusions, which are less than typical, become the focus of Campbell's paper, and Bayne and Pacherie's criticism of his work. Delusions are remarkably heterogeneous; this indeed may be part of the reason why there is so much difficulty in reaching a definition as Klee discusses, and occur in a wide variety of mental and neurological illnesses. The most common delusions are those of persecution and reference (World Health Organization [WHO] 1973) and typically occur in schizophrenia. By contrast, delusional misidentification occurs most commonly in patients with dementia, delirium, and focal cognitive impairment, but can occur in other functional psychoses such as an affective or schizophrenic psychosis. The most common form of delusional misidentification is not that of either the exotic Capgras or Fregoli syndromes but delusional misidentification for place; thus, although Bayne and Pacherie's arguments against Campbell may still hold, delusional misidentification tends to occur in the context of a patient believing that they are at home or on holiday rather than in hospital and may not necessarily involve close family members or other intimate relationships. Similarly, Cotard's syndrome tends to occur in the context of a severe depressive illness with mood-congruent psychotic symptoms, typically in an elderly individual. It does not have to have the content that the deluded is dead, but can include beliefs, for example, that the world no longer exists or that their internal organs are not present. Thus, a patient with either Capgras' or Cotard's syndrome is likely to differ from patients with delusions of persecution. They would [End Page 35] have different diagnoses, probably be older, and have a greater likelihood of structural abnormalities of the brain on imaging and consequent neuropsychological dysfunction. That is not to say that patients with schizophrenia have normal cerebral anatomy and neuropsychology, but rather that the Capgras' and Cotard's patients are likely to have neurological quality to their presentation that is clinically relevant, rather than what commonly the case in schizophrenia and the other functional psychoses, where the neurological abnormalities are only currently important at the level of academic research. Empirical Models of Delusion Formation Different delusions may not have that much in common, nor may the patients who believe in them. This in turn relates to the empirical paradigm that both Campbell and Bayne and Pacherie discuss. It is true that current research, and indeed the clinical practice of cognitive behavioral therapy for psychosis, is indebted to the work of Maher and it is within his legacy which we work. This, however, is not to say that we think his initial formulation was correct. Maher's (1988, 1992) work focused attempts in explaining delusions—both to support and refute his thesis that delusions are the consequence of normal cognitive mechanisms seeking to explain an anomalous sensory experience. Such a view initially led to work demonstrating delusions in the absence of anomalous perceptions, the presence of reasoning biases in the deluded population, and the possibility that abnormal sensory experience may be consequent upon biased cognitive processes (Garety and Freeman 1999). More recent work has demonstrated the prevalence of... (shrink)

Television medical dramas frequently depict the practice of medicine and bioethical issues in a strikingly realistic but sometimes inaccurate fashion. Because these shows depict medicine so vividly and are so relevant to the career interests of medical and nursing students, they may affect these students' beliefs, attitudes, and perceptions regarding the practice of medicine and bioethical issues. We conducted a web-based survey of medical and nursing students to determine the medical drama viewing habits and impressions of bioethical issues depicted in (...) them. More than 80% of medical and nursing students watch television medical dramas. Students with more clinical experience tended to have impressions that were more negative than those of students without clinical experience. Furthermore, viewing of television medical dramas is a social event and many students discuss the bioethical issues they observe with friends and family. Television medical dramas may stimulate students to think about and discuss bioethical issues. (shrink)

This is a review of Eklund's book. It discusses his suggestion that "ardent realists" use the practical profiles of normative concepts to A) explain what it is for a concept to be normative, B) fix reference, and C) provide an extensional theory of normative properties. I argue that those sympathetic to ardent realism will be happier to focus on the way in which normativity presents itself to cognition, particularly that presentation of inherent, authoritative guidance, and whether that 1) explains what (...) it is for a concept to be normative, 2) fixes reference, 3) aptly characterizes the nature of normativity in the world, and perhaps 4) explains why normative thoughts have the Eklund-style normative roles—the practical profiles of things like motivation, preference, and intention—that they have.

Businesses frequently exclude spiritual values, viewing such values as impositions that belong in business as much as a priest belongs at a bachelor party. Yet spirituality should not be viewed as impositions from without, but as inclusions from within. Spiritual values should be included in a company to the extent that these values are shared by the principals of a firm. Excluding spiritual values found in a “convergent consensus” runs contrary to freedom and liberty that Milton Friedman, among others, champions. (...) Furthermore, the exclusion of such values from a business threatens to alienate business persons from their moral integrity. By cultivating what I will call “the spiritual imagination,” businesses can facilitate fidelity between the convergent values of its principals, and the actions, policies, and culture of a company.

The view that innocent beneficiaries of injustice bear special duties to victims of injustice has recently come under attack. Luck egalitarian theorists have argued that thought experiments focusing on the way innocent beneficiaries should distribute the benefits they’ve received provide evidence against this view. The apparent special duties of innocent beneficiaries, they hold, are wholly reducible to general duties to compensate people for bad brute luck. In this paper we provide empirical evidence in defense of the view that innocent beneficiaries (...) have genuine special duties to victims of injustice. Through a series of four experiments, we show that judgments about the kinds of cases that luck egalitarian critics have provided do not undermine but rather support this view. We also explore a number of other questions that theorists working in this area have yet to discuss and provide suggestions for further research on the moral significance of benefiting from injustice.

In this article, we report a study in which 109 research-active mathematicians were asked to judge the validity of a purported proof in undergraduate calculus. Significant results from our study were as follows: (a) there was substantial disagreement among mathematicians regarding whether the argument was a valid proof, (b) applied mathematicians were more likely than pure mathematicians to judge the argument valid, (c) participants who judged the argument invalid were more confident in their judgments than those who judged it valid, (...) and (d) participants who judged the argument valid usually did not change their judgment when presented with a reason raised by other mathematicians for why the proof should be judged invalid. These findings suggest that, contrary to some claims in the literature, there is not a single standard of validity among contemporary mathematicians. (shrink)

The Oxford Handbook of the Reception of Aquinas provides a comprehensive survey of Catholic, Orthodox, and Protestant philosophical and theological reception of Thomas Aquinas over the past 750 years. This Handbook will serve as a necessary primer for everyone who wishes to study Aquinas's thought and/or the history of theology and philosophy since Aquinas's day. Part I considers the late-medieval receptions of Aquinas among Catholics and Orthodox. Part II examines sixteenth-century Western receptions of Aquinas (Protestant and Catholic), followed by a (...) chapter on sixteenth- and seventeenth-century Orthodox reception. Part III discusses seventeenth-century Protestant and Catholic receptions, and Part IV surveys eighteenth- and nineteenth-century receptions (Protestant, Orthodox, and Catholic). Parts V and VI focus on the twentieth century and takes into account the diversity of theological movements in the past century as well as extensive philosophical treatment. Parts VII and VIII unpick contemporary systematic approaches to Aquinas, covering the main philosophical and theological themes for which he is best known. With chapters written by a wide range of experts in their respective fields, this volume provides a valuable touchstone regarding the developments that have marked the past seven centuries of Christian theology.

This article looks at the strong links between Deleuze's molecular ontology and the fields of complexity and emergence, and argues that Deleuze's work implies a ‘philosophy of technology’ that is both open and dynamic. Following Simondon and von Uexküll, Deleuze suggests that technical objects are ontologically unstable, and are produced by processes of individuation and self-organization in complex relations with their environment. For Deleuze design is not imposed from without, but emerges from within matter. The fundamental departure for Deleuze, on (...) the basis of such an ontology, is to conceive of modes of relating to the evolution of technology. In this way Deleuze, along with Guattari, provides the basis for an ethics and a politics of becoming and emergent control that constitutes an alternative to the hubris of contemporary reductionist accounts of new areas such as nanotechnology.

Climate change poses a significant danger that requires intervention today; climate denial poses a key challenge to meaningful timely intervention. In this paper, we argue that current free speech jurisprudence in the US inadequately addresses the risk of climate change because it is overly permissive of ‘professional’ climate denial and underappreciates the need to address the future harm of climate change today. We begin by clarifying the risk posed by the Supreme Court's current approach to speech with respect to climate (...) change and, relatedly, reviewing the philosophical foundations of the marketplace of ideas found in the work of John Stuart Mill. Following this, we examine three potential ways in which Supreme Court jurisprudence could be used to limit what we term ‘professional climate change denial’ while permitting a degree of ‘private’ scepticism. Largely setting aside the return to earlier free speech jurisprudence and the extension of libel law, we offer a novel solution to the problem that suggests that ‘professional’ climate denial could be treated as a categorical exception under free speech jurisprudence and thus afforded a lower level of constitutional protection than other expression.

Typical analyses of belief in conspiracy theories have it that identifying as a conspiracy theorist is irrational. However, given that we know conspiracies occur, and theories about said conspiracies can be warranted, should we really be scared of the locution 'I'm a conspiracy theorist...'?

What is your understanding of the relationship between mind and brain for split-brain patients? (...) Do you believe that the mind can survive the death of the brain?

How do the ambiguities of decoherence affect the many-worlds interpretation? Could you expand on your answers to the two previous questions? Why isn't the conventional interpretation of quantum theory adequate? What about the Bohm interpretation? What about consistent histories? Does the present many-minds interpretation solve all the problems? (shrink)

The Bayesian Approach and the Classical Approach are two very different families of approaches to statistical inference. There are many different versions of each view, often with very substantial differences among them. But I will here endeavor to explain the philosophical core of each family of approaches, as well as to identify four main philosophical differences between them.

Social scientists are often interested in understanding how the dynamics of social systems are driven by the behavior of individuals that make up those systems. However, this process is hindered by the difficulty of experimentally studying how individual behavioral tendencies lead to collective social dynamics in large groups of people interacting over time. In this study, we investigate the role of social influence, a process well studied at the individual level, on the puzzling nature of success for cultural products such (...) as books, movies, and music. Using a “multiple‐worlds” experimental design, we are able to isolate the causal effect of an individual‐level mechanism on collective social outcomes. We employ this design in a Web‐based experiment in which 2,930 participants listened to, rated, and downloaded 48 songs by up‐and‐coming bands. Surprisingly, despite relatively large differences in the demographics, behavior, and preferences of participants, the experimental results at both the individual and collective levels were similar to those found in Salganik, Dodds, and Watts (2006). Further, by comparing results from two distinct pools of participants, we are able to gain new insights into the role of individual behavior on collective outcomes. We conclude with a discussion of the strengths and weaknesses of Web‐based experiments to address questions of collective social dynamics. (shrink)

We often knowingly teach false science. Such a practice conflicts with a prima facie pedagogical value placed on teaching only what’s true. I argue that only a partial dissolution of the conflict is possible: the proper aim of instruction in science is not to provide an armory of facts about what things the world contains, how they interact, and so on, but rather to contribute to an understanding of how science as a human endeavor works and what sorts of facts (...) about the world science aims to provide. Such an aim legislates for an increased prominence of history and philosophy in even secondary science education. (shrink)

This article challenges the claim that the rise of naturalism is devastating to religious belief. This claim hinges on an extreme interpretation of naturalism called scientism, the metaphysical view that science offers an exhaustive account of the real. For those committed to scientism, religious discourse is epistemically illegitimate, because it refers to matters that transcend—and so cannot be verified by—scientific inquiry. This article reconstructs arguments from the phenomenological tradition that seem to undercut this critique, viz., arguments that scientism itself cannot (...) be justified without recourse to matters that transcend scientific inquiry. If this is true, then scientism and religion share a cognitive conundrum: a commitment to truths that cannot in principle be known from our current perspective. (shrink)

ABSTRACTThis paper looks at the state of the literature surrounding Heidegger and Nazism today. Part 1 focusses on Hassan Givsan’s remarkable work, Une histoire consternante: pourquoi les philosophes se laissent corrompre par le “cas Heidegger”, which looks at the different, mutually inconsistent forms of “apologetics” denying that Heidegger had been a Nazi, or that this commitment could have been shaped by his philosophy. Part 2 looks at five themes that emerge from the 2014 French-language collection Heidegger, le sol, la communauté, (...) la race, edited by Emmanuel Faye: Heidegger’s anti-semitism, before and in the Black Notebooks; Sein und Zeit and “the political”; Heidegger and his estate’s post-war “rewriting” of his Nazi-era texts; Heidegger’s esotericism; and his intellectual proximities to other Nazi thinkers. Closing reflections touch on the state of the debate, calling for increased scholarly awareness of the evidence, and debate of its significance. (shrink)

I argue that Kroedel's 'Simple Argument' for downward causation fails and that this failure has consequences for any attempt to establish the reality of downward causation by appealing to counterfactual theories thereof. A central premise in Kroedel's argument equivocates. On one reading, it is true but renders the argument invalid; on another, it renders the argument valid but is likely false. I dedicate most of my efforts to establishing the second of these two claims. I show that the purported physical (...) effects of mental properties do not counterfactually depend upon the total realizers of these properties. If counterfactual dependence is necessary for causation, it follows that mental properties are not causes. If counterfactual dependence is merely sufficient for causation, it follows that no appeal to counterfactuals will by itself succeed in showing that mental properties are causes. (shrink)

This paper considers two competing pictures of knowledge of what one ought to do—one which assimilates this to other propositional knowledge conceived as partial ‘locational’ knowledge of where one is in a space of possibilities, the other which distinguishes this from other propositional knowledge by construing it as partial ‘directional’ knowledge of what to do in particular circumstances. I argue that the apparent tension can be lessened by better understanding the contextualized modal-cum-prescriptive nature of ‘ought’ and enriching our conception of (...) the kinds of possibilities within which we can locate ourselves.
