Kit Fine has proposed a new solution to what he calls ‘a familiar puzzle’ concerning modality and existence. The puzzle concerns the argument from the alleged truths ‘It is necessary that Socrates is a man’ and ‘It is possible that Socrates does not exist’ to the apparent falsehood ‘It is possible that Socrates is a man and does not exist’. We discuss in detail Fine’s setting up of the ‘puzzle’ and his rejection, with which we concur, of two mooted solutions (...) to it. (One of these uses standard, Kripkean, notions, and the other rests on work done by Arthur Prior.) We set out, and reject, the philosophy of modality underlying Fine’s new solution, and we defend an alternative response to the alleged puzzle. Our solution follows the work of David Wiggins in distinguishing between the sentential operator ‘It is necessary that’ and the predicate modifier ‘necessarily’. We briefly provide this distinction with a possible- world semantics on which it is neither a necessary truth, in some sense, that Socrates exists nor true, in some sense, that Socrates necessarily exists.

Immanuel Kant is known for his ideas about duty and morally worthy acts, but his conception of virtue is less familiar. Nevertheless Kant’s understanding of virtue is quite distinctive and has considerable merit compared to the most familiar conceptions. Kant also took moral education seriously, writing extensively on both the duty of adults to cultivate virtue and the empirical conditions to prepare children for this life-long responsibility. Our aim is, first, to explain Kant’s conception of virtue, second, to highlight some (...) distinctive and potentially appealing features of the Kantian account of virtue, third, to summarize and explain Kant’s prescriptions for educating young children and youth as well as the duty of moral self-improvement that he attributes to all adults, and, fourth, to respond to some common objections that we regard as misguided or insubstantial.

A theory of the structure and cognitive function of the human imagination that attempts to do justice to traditional intuitions about its psychological centrality is developed, largely through a detailed critique of the theory propounded by Colin McGinn. Like McGinn, I eschew the highly deflationary views of imagination, common amongst analytical philosophers, that treat it either as a conceptually incoherent notion, or as psychologically trivial. However, McGinn fails to develop his alternative account satisfactorily because (following Reid, Wittgenstein and Sartre) he (...) draws an excessively sharp, qualitative distinction between imagination and perception, and because of his flawed, empirically ungrounded conception of hallucination. His arguments in defense of these views are rebutted in detail, and the traditional, passive, Cartesian view of visual perception, upon which several of them implicitly rely, is criticized in the light of findings from recent cognitive science and neuroscience. It is also argued that the apparent intuitiveness of the passive view of visual perception is a result of mere historical contingency. An understanding of perception (informed by modern visual science) as an inherently active process enables us to unify our accounts of perception, mental imagery, dreaming, hallucination, creativity, and other aspects of imagination within a single coherent theoretical framework.

Some feminists hold that surrogacy contracts should be unenforceable or illegal because they contribute to and perpetuate unjust gender inequalities. I argue that in developed countries, surrogacy contracts either wouldn't have these negative effects or that these effects could be mitigated via regulation. Furthermore, the existence of a regulated surrogacy market is preferable on consequentialist grounds.

Clayton Littlejohn claims that the permissibility solution to the lottery paradox requires an implausible principle in order to explain why epistemic permissions don't agglomerate. This paper argues that an uncontentious principle suffices to explain this. It also discusses another objection of Littlejohn's, according to which we’re not permitted to believe lottery propositions because we know that we’re not in a position to know them.

Behavioural economics has taught us that human agents don't always display consistent, context-independent and stable preferences in their choice behaviour. Can we nevertheless do welfare economics...

Gideon Rosen and Robert Schwartzkopff have independently suggested (variants of) the following claim, which is a varian of Hume's Principle: -/- When the number of Fs is identical to the number of Gs, this fact is grounded by the fact that there is a one-to-one correspondence between the Fs and Gs. -/- My paper is a detailed critique of the proposal. I don't find any decisive refutation of the proposal. At the same time, it has some consequences which many will (...) find objectionable. (shrink)

Like American politics, the academic debate over justice is polarized, with almost all theories of justice falling within one of two traditions: egalitarianism and libertarianism. This book provides an alternative to the partisan standoff by focusing not on equality or liberty, but on the idea that we should give people the things that they deserve. Mulligan argues that a just society is a meritocracy, in which equal opportunity prevails and social goods are distributed strictly on the basis of merit. That (...) gives citizens their just deserts. In addition to its novel conceptual approach, meritocracy is distinctive from existing work in two ways. First, it is grounded in research on how people actually think about justice. Empirical research reveals that people don't think that social goods should be distributed equally. Nor do they dismiss the idea of social justice. Across ideological and cultural lines, people want rewards to reflect merit. Second, the book discusses hot-button political issues and makes concrete policy recommendations. These issues include anti-meritocratic bias against women and racial minorities and the United States’ widening economic inequality. Justice and the Meritocratic State offers a new theory of justice and provides solutions to our most vexing social and economic problems. It will be of keen interest to philosophers, economists, and political theorists. (shrink)

This paper argues that instrumental rationality is more permissive than expected utility theory. The most compelling instrumentalist argument in favour of separability, its core requirement, is that agents with non-separable preferences end up badly off by their own lights in some dynamic choice problems. I argue that once we focus on the question of whether agents’ attitudes to uncertain prospects help define their ends in their own right, or instead only assign instrumental value in virtue of the outcomes they may (...) lead to, we see that the argument must fail. Either attitudes to prospects assign non-instrumental value in their own right, in which case we cannot establish the irrationality of the dynamic choice behaviour of agents with non-separable preferences. Or they don’t, in which case agents with non-separable preferences can avoid the problematic choice behaviour without adopting separable preferences. (shrink)

The theory of science that Thomas Kuhn built in the Structure of Scientific Revolutions was considered as a hypothetical framework in this study. Since the publication of the work, many questions have arisen that call for a psychology of science. These questions are moved to another dimension through the knowledge of the decision made within Galileo Affair, which occupies an important place in modern science, fundamentally arising from an epistemic struggle and emerging out of an unscientific base rather than (...) the charge of unholiness. Abandoning the perspective which evaluates these questions within a historical process as a weak side of the Kuhnian theory of science, this study challenges the current approaches with an alternative approach. The epistemic complexity in the Kuhnian theory of science is an imperative complexity caused by human factors. From this perspective, there are potential questions for psychology of science as a field of study based on Kuhnian epistemology and it can be assumed that new problems may appear when the other epistemological questions which assumed as “answered” are reviewed in the scope of this study. The main thesis of this study is that psychology of science is possible as a valid and operationalizable research program based on Kuhnian theory of science. (shrink)

A window broke and Annie was involved. What’s of moral importance in a situation like this? Not whether Annie caused the window to break and not whether the window wouldn’t have broken if it weren’t for Annie. What’s morally important is whether Annie broke the window. In this thesis, I first generalise and argue for that claim; afterwards, I put it to work in ethics, applied ethics, and legal theory.

The epidemiologist Bradford Hill famously argued that in epidemiology, specificity of association (roughly, the fact that an environmental or behavioral risk factor is associated with just one or at most a few medical outcomes) is strong evidence of causation. Prominent epidemiologists have dismissed Hill’s claim on the ground that it relies on a dubious `one-cause one effect’ model of disease causation. The paper examines this methodological controversy, and argues that specificity considerations do have a useful role to play in causal (...) inference in epidemiology. More precisely, I argue that specificity considerations help solve a pervasive inferential problem in contemporary epidemiology: the problem of determining whether an exposure-outcome correlation might be due to confounding by a social factor. This examination of specificity has interesting consequences for our understanding of the methodology of epidemiology. It highlights how the methodology of epidemiology relies on local tools designed to address specific inference problems peculiar to the discipline, and shows that observational causal inference in epidemiology can proceed with little prior knowledge of the causal structure of the phenomenon investigated. I also argue that specificity of association cannot (despite claims to the contrary) be entirely explained in terms of Woodward’s well-known concept of “one-to-one” causal specificity. This is because specificity as understood by epidemiologists depends on whether an exposure (or outcome) is associated with a `heterogeneous’ set of variables. This dimension of heterogeneity is not captured in Woodward’s notion, but is crucial for understanding the evidential import of specificity of association. (shrink)

Un fait Mooréen, selon l'expression de David Lewis, est « l'une des choses que nous savons mieux que toute prémisse d'une argumentation philosophique visant à é tablir le contraire. » Le sujet des faits Mooréens soulève des questions profondes, à la fois de méthode philosophique et d'épistémologie de premier ordre. Comment devrions-nous répondre aux arguments qui remettent en question des croyances dont nous sommes extrêmement confiants ? Dans quelle mesure ces arguments – ou plutôt ceux qui les avancent – peuvent-ils (...) espérer avoir une emprise ou une traction rationnelle sur nous ? Dans quelle mesure, si même c'est le cas, notre point de départ limite-t-il les types de révisions de nos croyances que la philosophie pourrait légitimement inspirer ? Quand sommes-nous justifiés (si jamais nous le sommes) à refuser de se laisser influencer par un argument qui, pour autant qu'on puisse en juger, est sans faille, et quand un tel refus relève-t-il simplement du dogmatisme ? Ce sont là de vastes questions, auxquelles je ne tenterai pas ici de répondre complétement. Mon ambition, plus modeste, est de tenter de progresser sur ces questions, et d'autres questions connexes, en examinant la notion de fait Mooré que je trouve chez Lewis et chez d'autres. (shrink)

Lethal Autonomous Weapon Systems are here. Technological development will see them become widespread in the near future. This is in a matter of years rather than decades. When the UN Convention on Certain Conventional Weapons meets on 10-14th November 2014, well-considered guidance for a decision on the general policy direction for LAWS is clearly needed. While there is widespread opposition to LAWS—or ‘killer robots’, as they are popularly called—and a growing campaign advocates banning them outright, we argue the opposite. LAWS (...) may very well reduce suffering and death in war. Rather than banning them, they should be regulated, to ensure both compliance with international humanitarian law, and that this positive outcome occurs. This policy memo sets out the basic structure and content of the regulation required. (shrink)

Given any proposition, is it possible to have rationally acceptable attitudes towards it? Absent reasons to the contrary, one would probably think that this should be possible. In this paper I provide a reason to the contrary. There is a proposition such that, if one has any opinions about it at all, one will have a rationally unacceptable set of propositional attitudes—or if one doesn’t, one will end up being cognitively imperfect in some other manner. The proposition I am concerned (...) with is a self-referential propositional attitude ascription involving the propositional attitude of rejection. Given a basic assumption about what constitutes irrationality, and a few assumptions about the nature of cognitively ideal agents, a paradox results. This paradox is superficially like the Liar, but it is importantly different in that no alethic notions are involved at all. As such, it stands independent of the Liar and is not a ‘revenge’ version of it. After setting out the paradox I discuss possible responses. After considering several I argue that one is best off simply accepting that the paradox shows us something surprising and interesting about rationality: that some cognitive shortfall is unavoidable even for ideal agents. I argue that nothing disastrous follows from accepting this conclusion. (shrink)

Michael Sandel’s latest book is not a scholarly work but is clearly intended as a work of public philosophy—a contribution to public rather than academic discourse. The book makes two moves. The first, which takes up most of it, is to demonstrate by means of a great many examples, mostly culled from newspaper stories, that markets and money corrupt—degrade—the goods they are used to allocate. The second follows from the first as Sandel’s proposed solution: we as a society should deliberate (...) together about the proper meaning and purpose of various goods, relationships, and activities (such as baseball and education) and how they should be valued. -/- Public philosophy is a different genre from academic philosophy, but that does not mean that it cannot be held to high standards. In my view, while this book does provide food for thought and food for conversation, it nevertheless has significant failings as a work of public philosophy rather than journalistic social activism on the model of Naomi Klein’s No logo (1999).

The term ‘continuous’ in real analysis wasn’t given an adequate formal definition until 1817. However, important theorems about continuity were proven long before that. How was this possible? In this paper, I introduce and refine a proposed answer to this question, derived from the work of Frank Jackson, David Lewis and other proponents of the ‘Canberra plan’. In brief, the proposal is that before 1817 the meaning of the term ‘continuous’ was determined by a number of ‘platitudes’ which had some (...) special epistemic status. (shrink)

Das Wiskott-Aldrich-Syndrom (WAS), ein genetisch bedingter Immundefekt mit klinischer Manifestation im Kleinkindalter, wird voraussichtlich in näherer Zukunft erstmals versuchsweise durch eine somatische Gentherapie behandelt werden. Im vor- liegenden Beitrag werden die wichtigsten medizinisch-naturwissenschaftlichen Fakten dieses Krankheitsbildes sowie die bisherigen Erfahrungen mit somatischen Gentherapien bei anderen Immunmangelsyndromen ausführlich dargestellt. Sodann erfolgt eine ethische Analyse eines möglichen gentherapeutischen Eingriffs bei WAS-Patienten, bei der die spezifischen Aspekte des Wiskott-Aldrich-Syndroms – insbesondere die fast ausschließliche Betroffenheit von Kindern sowie die unterschiedlich aussichtsreiche Alter- nativoption einer (...) allogenen Knochenmarktransplantation–wesentliche Aspekte der Beurteilung sind. Im Ergebnis zeigt sich, dass ein gentherapeutischer Eingriff im vorliegenden Fall nicht im Rahmen einer Forschungsstudie, d.h. als Humanexperiment, gerechtfertigt werden kann, sondern allein als individueller Heilversuch. Gleichwohl las- sen die besonderen Risiken und die Innovativität eines solchen Eingriffs es notwendig erscheinen, diesen Heilversuch – anders als andere Heilbehandlungen mit bislang unerprobten Mitteln – in streng kontrollierter Form durchzuführen. Der neuartige Gedanke eines kontrollierten individuellen Heilversuchs zeichnet sich daher für den vorliegenden Fall, und womöglich auch für vergleichbare risikoreiche Behandlungsansätze namentlich im Bereich der Gentherapie, als geeignetes Instrument der Konzeption und Beurteilung ab.

Considérez les énoncés suivants : « La bombe a causé la destruction du pont » ; « L’explosion de la bombe a causé la destruction du pont » ; « Booth a causé la mort de Lincoln » ; et « Le tir de Booth a causé la mort de Lincoln ». Ces énoncés suggèrent que les objets, tels que les bombes ou les personnes, font partie de la catégorie ontologique des causes, au même titre que les évènements, comme le (...) tir de Booth et l’explosion de la bombe. À première vue, le fait que les objets et les personnes puissent être des causes n’a rien de particulièrement surprenant. Cependant, les philosophes du XXe siècle ont fait preuve d’une extrême méfiance à l’égard de cette idée. Une majorité de philosophes ont trouvé l’idée même de causalité par des objets ou des agents inintelligible, à tel point que les théories standards de la causalité présupposent que les entités reliées comme causes à effets sont des évènements, ou encore des faits, des propriétés ou des états. Pourtant, cette hostilité à l’égard de la causalité des objets est relativement récente ; la causalité agentive semble, au moins jusqu’à Thomas Reid (1710-1796), avoir été la norme, et non le mystère. La mise à l’écart des objets et des agents de la catégorie de cause est-elle justifiée ? Un nombre grandissant de philosophes, les agentialistes (agent-causalists), soutiennent que non et cherchent à réhabiliter l’idée de causalité agentive (par des agents) et/ou substantielle (par des substances), tandis que d’autres, les évènementialistes (event-causalists), défendent que celle-ci est au mieux réductible à la causalité entre évènements, ou au pire que l’idée est incohérente. L’importance de cette question n’est pas négligeable, car elle revient à demander quels sont les moteurs du changement. En effet, nous voulons savoir si certains objets tels que les couteaux, les bombes, les animaux et les personnes sont parfois à l’origine du changement, ou si tout effet procède uniquement de changements antérieurs, d’évènements. Existe-t-il une relation causale, la causalité agentive ou substantielle, reliant objets et changements, différente des relations causales habituellement traitées par les philosophes de la causalité ? Quelle est sa relation avec la causalité évènementielle ? Et comment fonctionne-t-elle ? (shrink)

Thomas Hurka’s recursive account of value appeals to certain intuitions to expand the class of intrinsic values, placing concepts of virtue and desert within the realm of second and third order intrinsic goods, respectively. This is a formalization of a tradition of thought extending back to Aristotle and Kant via the British moralists, G. E. Moore, and W. D. Ross. However, the evidential status of such intuitions vis a vis the real, intrinsic value of virtue and desert is hostage (...) to alternative explanations. If there is a plausible competing explanation for these intuitions, then the (putative) fact that desert and virtue are intrinsic (rather than instrumental or derivative) goods seems a much less obvious choice for the best explanation. As it turns out, there are plausible evolutionary explanations for these intuitions about desert and virtue. These evolutionary explanations suggest that it is adaptive to value desert and virtue separately from their instrumentality for other goods. Consequently, these explanations debunk intuitions about the intrinsic value of desert and virtue. (shrink)

Discussions concerning whether there is a natural right to health care may occur in various forms, resulting in policy recommendations for how to implement any such right in a given society. But health care policies may be judged by international standards including the UN Universal Declaration of Human Rights. The rights enumerated in the UDHR are grounded in traditions of moral theory, a philosophical analysis of which is necessary in order to adjudicate the value of specific policies designed to enshrine (...) rights such as a right to health care. We begin with an overview of the drafting of the UDHR and highlight the primary influence of natural law theory in validating the rights contained therein. We then provide an explication of natural law theory by reference to the writings of Thomas Aquinas, as well as elucidate the complementary “capabilities approach” of Martha Nussbaum. We conclude that a right to health care ought to be guaranteed by the state. (shrink)

This paper addresses several questions related to the nature, production, and use of animal-human (a-h) chimeras. At the heart of the issue is whether certain types of a-h chimeras should be brought into existence, and, if they are, how we should treat such creatures. In our current research environment, we recognize a dichotomy between research involving nonhuman animal subjects and research involving human subjects, and the classification of a research protocol into one of these categories will trigger different ethical standards (...) as to the moral permissibility of the research in question. Are a-h chimeras entitled to the more restrictive and protective ethical standards applied to human research subjects? We elucidate an Aristotelian-Thomistic metaphysical framework in which to argue how such chimeras ought to be defined ontologically. We then examine when the creation of, and experimentation upon, certain types of a-h chimeras may be morally permissible. (shrink)

How does Locke contribute to the development of 18th-century projects for a science of the mind, even though he seems to reject or at least bracket off such an idea himself? Contrary to later understandings of empiricism, Locke goes out of his way to state that his project to investigate and articulate the ‘logic of ideas’ is not a scientific project: “I shall not at present meddle with the Physical consideration of the Mind” (Essay, I.i.2). Locke further specifies that this (...) means his analysis of mental processes will not engage with knowledge of the brain (e.g. in terms of corpuscles and animal spirits), even though he had been the student of Thomas Willis. Now, Kant seemed to make an elementary mistake, given such a clear statement on Locke’s part, when he claimed that Locke’s project was a “physiology of the understanding” (in the Preface to the A edition of the first Critique). One can ask of course what this physiology of the understanding was, and if it existed, in or out of the Lockean intellectual world (as I have sought to investigate in a 2016 paper). This leads me to inquire into the outcome of his empiricism for a scientific treatment of the mind, including in the sense of a ‘naturalization’ of the mind (with implications also for our understanding of empiricism: Anstey’s influential distinction between experimental and speculative philosophy does not seem useful here). Because if Kant made this charge, there were also many 18th-century thinkers who positively treated Locke as their great forerunner in psychology and related fields: Charles Bonnet and Joseph Priestley among them, just as some prominent physicians such as Cabanis claimed to be ‘finishing the job’ that Locke had started in, e.g. their materialist theories of the passions. What one might term ‘the Locke Problem’ here is: how can one reconcile empiricism and claims about cerebral processes, while seeking to remain a Lockean? Differently put, what is the process of naturalization, a naturalization of? (shrink)

Abstract -/- Before Descartes, middle age philosophers like Thomas Aquinas (1225-1274), Duns Scotus (1266-1308), and Francisco Suarez (1548-1617) used to discuss the distinction between essence and existence in three ways (of course, Ibn-Sina was the first who made this distinction to rehabilitate Aristotelian philosophy in the Islamic heritage). Descartes was aware of that, but discussed it according to the relation between mind and body. Yet, he told us many times that he was used to separate essence from existence in (...) metaphysical issues. The objective of this paper is first to rephrase his untold opinion about the relation between essence and existence on the basis of his conception of the problem of distinction according to mind and body, and second, to disclose that Descartes's conception of existence is twofold. At the end, it is claimed that his twofold notion of existence and his inability to overcome it, is the principal factor in his failure to explicate everything according to first principles, and so in his failure to defeat skepticism.

"No, your honor. I didn't know who or what he was when I first came across the book -- they don't exactly love him in the synagogue, if you've read the story of his life. I found it in a junkyard in a nearby town, paid a kopek, and left cursing myself for wasting money hard to come by. Later I read through a few pages and kept on going as though there were a whirlwind at my back. As I (...) say, I didn't understand every word but when you're dealing with such ideas you feel as though you were taking a witch's ride. After that I wasn't the same man. That's in a manner of speaking, of course, because I've changed little since my youth.". The speaker is Yakov Bok, the unlikely hero of Bernard Malamud's The Fixer. At this point, early in the novel, Yakov speaks truthfully when he says that he has changed little since his youth. But over the next two and a half years (the time-period covered in the novel), he will undergo profound change and impressive moral growth. He suffers; he learns; he grows. Spinoza's name and ideas appear again and again at crucial moments in the course of the hero's moral development. Yakov Bok's verbal account of Spinoza's ideas is often comically primitive, but his understanding far outstrips his ability to articulate. By the end of the novel, his sufferings have led him to a deep grasp of certain of Spinoza's ethical and political doctrines. (shrink)

This is Part 2 of a four part paper, intended as an introduction to the key concepts and issues of time directionality for physicists and philosophers. It redresses some fundamental confusions in the subject. These need to be corrected in introductory courses for physics and philosophy of physics students. Here we analyze the quantum mechanical time reversal operator and the reversal of the deterministic Schrodinger equation. It is argued that quantum mechanics is anti-symmetric w.r.t. time reversal in its deterministic laws. (...) This contradicts the orthodox analysis, found throughout the conventional literature on physical time, which claims that quantum mechanics is time symmetric (reversible), and that we must adopt the anti-unitary operator (T*) instead of the unitary time reversal operator (T) for time reversal in quantum mechanics. This is widely claimed as settled scientific fact, and large metaphysical conclusions about the symmetry of time are drawn from it. But it is an error. (shrink)

Those who oppose human embryonic stem cell research argue for a clear position on the metaphysical and moral status of human embryos. This position does not differ whether the embryo is present inside its mother’s reproductive tract or in a cryopreservation tank. It is worth examining, however, whether an embryo in “suspended animation” has the same status as one actively developing in utero. I will explore this question from the perspective of Thomas Aquinas’s metaphysical account of human nature. I (...) conclude that a cryopreserved human embryo counts, both metaphysically and morally, as a person; and thus the utilization of such embryos for inherently destructive research purposes is impermissible.

In a series of papers, Thomas P. Flint has posited that God the Son could become incarnate in any human person as long as certain conditions are met (Flint 2001a, 2001b). In a recent paper, he has argued that all saved human persons will one day become incarnated by the Son (Flint 2011). Flint claims that this is motivated by a combination of Molinism and orthodox Christology. I shall argue that this is unmotivated because it is condemned by orthodox (...) Christology. Flint has unknowingly articulated a version of the heresy called Origenism that is condemned by the Fifth Ecumenical Council. After arguing that Flint’s account is unmotivated because it is condemned, I shall offer some reflections and prolegomena on the relationship between contemporary analytic theology and the ecumenical creeds.

This is Part 1 of a four part paper, intended to redress some of the most fundamental confusions in the subject of physical time directionality, and represent the concepts accurately. There are widespread fallacies in the subject that need to be corrected in introductory courses for physics students and philosophers. We start in Part 1 by analysing the time reversal symmetry of quantum probability laws. Time reversal symmetry is defined as the property of invariance under the time reversal transformation, T: (...) t --> -t. It is shown that quantum mechanics (classical or relativistic) is strongly time asymmetric in its probability laws. This contradicts the orthodox analysis, found throughout the conventional literature on physical time, which claims that quantum mechanics is time symmetric or reversible. This is widely claimed as settled scientific fact, and large philosophical and scientific conclusions are drawn from it. But it is an error. The fact is that while quantum mechanics is widely claimed to be reversible on the basis of two formal mathematical properties (that it does have), these properties do not represent invariance under the time reversal transformation. A recent experiment (Batalhão at alia, 2015) showing irreversibility of quantum thermodynamics is discussed as an illustration of this result. Most physicists remain unaware of the errors, decades after they were first demonstrated. Orthodox specialists in the philosophy of time who are aware of the error continue to refer to the ‘time symmetry’ or ‘reversibility’ of quantum mechanics anyway – and exploit the ambiguity to claim false implications about physical time reversal symmetry in nature. The excuse for perpetrating the confusion is that, since it is has now become customary to refer to the formal properties of quantum mechanics as ‘reversibility’ or ‘time reversal symmetry’, we should just keep referring to them by this name, even though they are not time reversal symmetry. This causes endless confusion, in attempts to explain the physical irreversibility of our universe, and in philosophical discussions of implications of physics for the nature of time. The failure of genuine time reversal symmetry in quantum mechanics changes the interpretation of modern physics in a deep way. It changes the problem of explaining the real irreversibility found throughout nature. (shrink)

Transoral laser microsurgery applies to the piecemeal removal of malignant tumours of the upper aerodigestive tract using the CO2 laser under the operating microscope. This method of surgery is being increasingly popularised as a single modality treatment of choice in early laryngeal cancers (T1 and T2) and occasionally in the more advanced forms of the disease (T3 and T4), predomi- nantly within the supraglottis. Thomas Kuhn, the American physicist turned philosopher and historian of science, coined the phrase ‘paradigm shift’ (...) in his groundbreaking book The Structure of Scientific Revolutions. He argued that the arrival of the new and often incompatible idea forms the core of a new paradigm, the birth of an entirely new way of thinking. This article discusses whether Steiner and col- leagues truly brought about a paradigm shift in oncological surgery. By rejecting the principle of en block resection and by replacing it with the belief that not only is it oncologically safe to cut through the substance of the tumour but in doing so one can actually achieve better results, Steiner was able to truly revolutionise the man- agement of laryngeal cancer. Even though within this article the repercussions of his insight are limited to the upper aerodigestive tract oncological surgery, his willingness to question other peoples’ dogma makes his contribution truly a genuine paradigm shift.

The analysis of the reversibility of quantum mechanics depends upon the choice of the time reversal operator for quantum mechanical states. The orthodox choice for the time reversal operator on QM states is known as the Wigner operator, T*, where * performs complex conjugation. The peculiarity is that this is not simply the unitary time reversal operation, but an anti-unitary operator, involving complex conjugation in addition to ordinary time reversal. The alternative choice is the Racah operator, which is simply ordinary (...) time reversal, T. Orthodox treatments hold that it is either logically or empirically necessary to adopt the Wigner operator, and the Racah operator has received little attention. The basis for this choice is analysed in detail, and it is concluded that all the conventional arguments for rejecting the Racah operator and adopting the Wigner operator are mistaken. The additional problem of whether the deterministic part of quantum mechanics should be judged to be reversible or not is also considered. The adoption of the Racah operator for time reversal appears prima facie to entail that quantum mechanics is irreversible. However, it is concluded that the real answer to question depends upon the choice of interpretation of the theory. In any case, the conventional reasons for claiming that quantum mechanics is reversible are incorrect. (shrink)

Objectives. The purpose of this study was to conduct the first randomized controlled trial (RCT) to evaluate the effectiveness of a second-generation mindfulness-based intervention (SG-MBI) for treating fibromyalgia syndrome (FMS). Compared to first generation mindfulness-based interventions, SG-MBIs are more acknowledging of the spiritual aspect of mindfulness. Design. A RCT employing intent-to-treat analysis. Methods. Adults with FMS received an 8-week SG-MBI known as meditation awareness training (MAT; n = 74) or an active control intervention known as cognitive behaviour theory for groups (...) (n = 74). Assessments were performed at pre-, post-, and 6-month follow-up phases. Results. Meditation awareness training participants demonstrated significant and sustained improvements over control group participants in FMS symptomatology, pain perception, sleep quality, psychological distress, non-attachment (to self, symptoms, and environment), and civic engagement. A mediation analysis found that (1) civic engagement partially mediated treatment effects for all outcome variables, (2) non-attachment partially mediated treatment effects for psychological distress and sleep quality, and (3) non-attachment almost fully mediated treatment effects for FMS symptomatology and pain perception. Average daily time spent in meditation was found to be a significant predictor of changes in all outcome variables. Conclusions. Meditation awareness training may be a suitable treatment for adults with FMS and appears to ameliorate FMS symptomatology and pain perception by reducing attachment to self. (shrink)

We examine some of Connes’ criticisms of Robinson’s infinitesimals starting in 1995. Connes sought to exploit the Solovay model S as ammunition against non-standard analysis, but the model tends to boomerang, undercutting Connes’ own earlier work in functional analysis. Connes described the hyperreals as both a “virtual theory” and a “chimera”, yet acknowledged that his argument relies on the transfer principle. We analyze Connes’ “dart-throwing” thought experiment, but reach an opposite conclusion. In S , all definable sets of reals are (...) Lebesgue measurable, suggesting that Connes views a theory as being “virtual” if it is not definable in a suitable model of ZFC. If so, Connes’ claim that a theory of the hyperreals is “virtual” is refuted by the existence of a definable model of the hyperreal field due to Kanovei and Shelah. Free ultrafilters aren’t definable, yet Connes exploited such ultrafilters both in his own earlier work on the classification of factors in the 1970s and 80s, and in Noncommutative Geometry, raising the question whether the latter may not be vulnerable to Connes’ criticism of virtuality. We analyze the philosophical underpinnings of Connes’ argument based on Gödel’s incompleteness theorem, and detect an apparent circularity in Connes’ logic. We document the reliance on non-constructive foundational material, and specifically on the Dixmier trace −∫ (featured on the front cover of Connes’ magnum opus) and the Hahn–Banach theorem, in Connes’ own framework.

These doctrines remained controversial within confessional traditions after the Reformation, as Dominicans and Jesuits and later Calvinists and Arminians argued about these critical issues in the Augustinian theological heritage. Some of those involved in condemning Arminianism at the Synod of Dordt (1618-1619) were inspired by Dominican followers of Thomas Aquinas in Spain who had recently opposed the vigorous defense of free (...) choice by Jesuit Molinists in the Congregatio de auxiliis (1598-1607). This volume, appearing on the 400th anniversary of the closing of the Synod of Dordt, brings together a group of scholars working in fields that only rarely speak to one another to address these theological debates that cross geographical and confessional boundaries.

The concept of empiricism evokes both a historical tradition and a set of philosophical theses. The theses are usually understood to have been developed by Locke, Berkeley, and Hume. But these figures did not use the term “empiricism,” and they did not see themselves as united by a shared epistemology into one school of thought. My dissertation analyzes the debate that elevated the concept of empiricism (and of an empiricist tradition) to prominence in English-language philosophy. -/- In the 1870s and (...) ’80s a lively debate about psychology emerged. Neo-Kantian idealists criticized the very idea that the mind can be studied scientifically. A group of philosopher-psychologists responded, often in Mind. They were among the first to call themselves “empiricists,” arguing that psychology could provide a scientific basis for philosophical progress. Idealists held that empirical psychology depended on premises developed by Locke, Berkeley, and Hume. These premises were allegedly absurd because they rendered ideas of extension, as well as other ideas crucial to natural science, unreal. Those who wanted to advance psychology towards becoming a legitimate science were forced to engage these philosophical attacks, while at the same time to develop empirical theories that could successfully explain some characteristics of experience. I show how James’s theory of space perception accomplished both tasks. -/- In developing this theory, James found he had to reject the Lockean notion that reality is associated with passively-registered sensations. James also abandoned Berkeley and Hume’s claim that ideas are ultimately derived from atomic sensations. Instead, James presented experimental evidence that sensation is a continuous stream. The mind must actively parse this stream if it is to gain a coherent representation of its environment. I argue that James’s stream-of-thought thesis served as a presupposition of his entire psychology. The thesis showed how the labor of investigating the mind could be divided between philosophers and scientists, and in a manner sensitive to the concerns of both. The stream thesis also provided a scientific basis for a new philosophical empiricism that, I argue, has a hidden legacy in the history of analytic philosophy. (shrink)

In this dialogue Thomas A and Jeito intuitively discuss the difference between a miracle and a fact. They conclude that the doings of God aren’t miracles.

In recent work, Thomas Kroedel has proposed a novel solution to the lottery paradox. As he sees it, we are permitted/justified in believing some lottery propositions, but we are not permitted/justified in believing them all. I criticize this proposal on two fronts. First, I think that if we had the right to add some lottery beliefs to our belief set, we would not have any decisive reason to stop adding more. Suggestions to the contrary run into the wrong kind (...) of reason problem. Reflection on the preface paradox suggests as much. Second, while I agree with Kroedel that permissions do not agglomerate, I do not think that this fact can help us solve the lottery paradox. First, I do not think we have any good reason to think that we’re permitted to believe any lottery propositions. Second, I do not see any good reason to think that epistemic permissions do not agglomerate. (shrink)

This study investigates Thomas Kuhn’s philosophy that had broad influence in philosophy of science by his book The Structure of Scientific Revolutions, and the contributions of his philosophy to Turkish philosophical literature. Kuhnian part of the picture of science debates brings to light considering the works done in Turkey upon the philosophy of Kuhn. In the first part of the thesis, T. Kuhn's life and works are mentioned. The second part focuses on Kuhn's philosophy of science and the concept (...) of paradigm. In the third part, publications on the Kuhnian understanding of science are determined and in the fourth part, finally, general evaluations are made on these publications and studies. (shrink)

Thomas Garrigue Masaryk, later founder and President of the Republic of Czechoslovakia, studied philosophy in the University of Vienna from 1872 to 1876, where he came under the powerful influence of Franz Brentano. We survey the role of Brentano’s philosophy, and especially of his ethics, in Masaryk’s life and work.

A philosopher's inquiry on travel may take different paths. Emily Thomas follows several in The Meaning of Travel, where she uncovers novel philosophical debates such as the ontology of maps or the ethics of ‘doom tourism’. Perhaps unexpectedly for the reader, Thomas also offers accessible and engaging discussions on—mostly Early—Modern philosophy by connecting travel-related topics to the work of some well-known authors (René Descartes and Francis Bacon), some unjustly neglected ones (Margaret Cavendish) and some known mostly to specialists (...) (Henry More). The result of this bric-a-brac approach is mostly positive: Thomas's work stands out as an entertaining, insightful read, suitable for a wide readership, whilst also having the potential to be a foundational text in the philosophy of travel. And I agree with Thomas: philosophy of travel ‘isn’t a thing, but it should be’ (p. 3). (shrink)

I begin by sketching the Epicurean position on death - that it cannot be bad for the one who dies because she no longer exists - which has struck many people as specious. However, alternative views must specify who is wronged by death (the dead person?), what is the harm (suffering?), and when does the harm take place (before death, when you’re not dead yet, or after death, when you’re not around any more?). In the second section I outline the (...) most sophisticated anti-Epicurean view, the deprivation account, according to which someone who dies is harmed to the extent that the death has deprived her of goods she would otherwise have had. In the third section I argue that deprivation accounts that use the philosophical tool of possible worlds have the counterintuitive implication that we are harmed in the actual world because counterfactual versions of us lead fantastic lives in other possible worlds. In the final section I outline a neo-Epicurean position that explains how one can be wronged by being killed without being harmed by death and how it is possible to defend intuitions about injustice without problematic appeal to possible worlds.

Among the terrestrial species, the majority 332 species is represented by small Volant and non Volant species belonging to the orders Vandeleuria is a small genus of rodent also known long-tailed climbing mouse. Vandeleuria Nilagirica is a Subspecies of Vandelueuria Olaracia species is divided by geographical variations and morphological characterized described namely dumeticola Hodgson, Nilagirica Jerodon, Spandicea Ryley, Rubida Thomas, Modesta Thomas, and Nolthenii Phillips as its Sub Species and the synonymized wrought on Ryley with the nominate sub (...) species and Provensis Hodgson, badius Blyth and marica Thomas with dumesticola Hodgson (V.V Agarwal and Chakraborty 1980). Vandeleuria nilagirica is longer tails, arboreal,It is very shy Nocturnal and omnivore, feeding is usually the spruce leaves and small flower sand buds of small plants that includes small insects also. IUCN status of this species is Endangered. This species is Endamic to the tropical forest along the Northern Western Ghats, Nilgiri Hills (Musses & Carleton 2005). Species altitudinal range is 900 to 2100 M. Theses are found in mountainous areas where there is no hassle. It is Listed as a under scheduled ‘V’ of the Indian wild life Act. As compared to other zones, the frequency of occurrence of F. pennanti and B. bandicota was found to be very low at all the localities in southeastern Rajasthan. Some of the hills have been afforested and the plantations have a very low herbaceous ground cover. This may be one of the reasons of low occurrence of the long-tailed tree mouse, Vandeleuriaoleracea. Suncus stoliczkanus, the Anderson’s shrew was found to be absent in this zone (Ishwar prakash & Himmat Singh 2001). In Thar desert Maximum number of Vandeleuria oleracea 66.6% Species Was observed ( Prakash I,PratapSingh 2005) .Human Disturbance, floods, habitat loss & degradation found to be major threat to these species. This small mammal is plays in important role in the Environment. (shrink)

Based on a recently published essay by Jeremy Gwiazda, I argue that the possibility that the present state of the universe is the product of an actually infinite series of causally-ordered prior events is impossible in principle, and thus that a major criticism of the Secunda Via of St. Thomas is baseless after all.

According to a prominent view in Jewish-Halakhic literature, “mitzvot (commandments) require intention.” That is, to fulfill one’s obligation in performing a commandment, one must intend to perform the act because it’s a mitzvah; one must take the fact that one’s act is a mitzvah as her reason for doing the action. I argue that thus understood, this Halakhic view faces a revised version of Thomas Hurka’s recent dilemma for structurally similar views in ethics: either it makes it a necessary (...) condition for the act’s being a mitzvah that one has a false belief about the act’s Halakhic status, or it commits proponents of the “mitzvot require intention” view to a sort of rational failure in performing the mitzvot. The dilemma arises, however, only if we interpret this Halakhic view as requiring one to have a belief about her act’s Halakhic status in order for it to have this status. I suggest that the dilemma can be avoided by interpreting the intention requirement as requiring a make-belief, instead of a belief. Under this understanding, Halakha (or God) doesn’t care about why one performs an act of a mitzvah, but rather about how she does it; how she sees and experiences her action. This suggests another form of worship central to Judaism—worship via make-believing. (shrink)
