We introduce an implication-with-possible-exceptions and define validity of rules-with-possible-exceptions by means of the topological notion of a full subset. Our implication-with-possible-exceptions characterises the preferential consequence relation as axiomatized by Kraus, Lehmann and Magidor [Kraus, Lehmann, and Magidor, 1990]. The resulting inference relation is non-monotonic. On the other hand, modus ponens and the rule of monotony, as well as all other laws of classical propositional logic, are valid-up-to-possible exceptions. As a consequence, the rules of classical propositional logic do not determine the (...) meaning of deducibility and inference as implication-without-exceptions. (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Book Three of George Santayana's letters covers a period of intense intellectual activity in Santayana's life, and the correspondence reflects the establishment of his mature philosophy. Santayana becomes more permanently established in Italy, but continues to travel in France, Spain, and England. The year 1927 marks the beginning of his long friendship with Daniel Cory, who became his literary secretary and eventually his literary executor. Also, with the death of Santayana's half-brother Robert, George Sturgis, Robert's son, becomes an important part (...) of Santayana's life and letters as his financial manager. Santayana continues to write to his sister Susana, as well as to numerous friends and fellow philosophers, including Bernard Berenson, Robert Seymour Bridges, Curt John Ducasse, John Erskine, Horace Meyer Kaller, Lewis Mumford, George Herbert Palmer, John Francis Stanley Russell, Herbert Wallace Schneider, Charles Augustus Strong, Paul Weiss, and Harry Austryn Wolfson. Other correspondents include Wendell T. Bush, Alys Gregory, Marianne Moore, John Middleton Murray, and Frederick J. E. Woodbridge. (shrink)

It has recently been argued by Gabriel Herman that fourth-century Athenian citizens, or at least the majority of them, believed that even under the impact of serious private aggression a man should not pursue revenge. The general ideal, so it is maintained, was to avoid not only violent revenge but also revenge through prosecution. Herman recognizes that other Athenian texts of the same period take the propriety of exacting revenge for granted, and he explains this in part by (...) reference to a supposed ‘double standard’—a rather strange expression in this context, because it suggests that the propriety of revenge in classical Athens depended on the status of the victim of the revenge—which is not in fact the burden of Herman's doctrine.

We introduce a St. Petersburg-like game, which we call the ‘Pasadena game’, in which we toss a coin until it lands heads for the first time. Your pay-offs grow without bound, and alternate in sign (rewards alternate with penalties). The expectation of the game is a conditionally convergent series. As such, its terms can be rearranged to yield any sum whatsoever, including positive infinity and negative infinity. Thus, we can apparently make the game seem as desirable or undesirable as we (...) want, simply by reordering the pay-off table, yet the game remains unchanged throughout. Formally speaking, the expectation does not exist; but we contend that this presents a serious problem for decision theory, since it goes silent when we want it to speak. We argue that the Pasadena game is more paradoxical than the St. Petersburg game in several respects. We give a brief review of the relevant mathematics of infinite series. We then consider and rebut a number of replies to our paradox: that there is a privileged ordering to the expectation series; that decision theory should be restricted to finite state spaces; and that it should be restricted to bounded utility functions. We conclude that the paradox remains live. (shrink)

Selective serotonin reuptake inhibitors (SSRIs) have gained a degree of prominence across recent moral enhancement literature as a possible intervention for dealing with antisocial and aggressive impulses. This is due to serotonin's purported capacity to modulate persons’ averseness to harm. The aim of this article is to argue that the use of SSRIs is not something worth getting particularly excited about as a practicable intervention for moral enhancement purposes, and that the generally uncritical enthusiasm over serotonin's potential as a moral (...) enhancer is a consequence of the paucity of viable options for envisaging practicable moral enhancement interventions. While there are many conceptual issues raised by the idea of moral enhancement generally, and by the idea of serotonin as a morally affective agent, the aim here is to look at practical concerns. It is argued that SSRIs do not, nor cannot in the reasonably foreseeable future, be made to work as a reliably safe or reliably effective means for moral enhancement, even within the very limited remit of treating “reactive” aggression. SSRIs might be effective as a limited and partial mental health intervention (even this is questionable), but not as a generally effective moral enhancement technology. (shrink)

This paper discusses the role of consent in decision making generally and its role in end of life decisions in particular. It outlines a conception of autonomy which explains and justifies the role of consent in decision making and criticises some misapplications of the idea of consent, particular the role of fictitious or “proxy” consents.Where the inevitable outcome of a decision must be that a human individual will die and where that individual is a person who can consent, then that (...) decision is ethical if and only if the individual consents. In very rare and extreme cases such a decision will be ethical in the absence of consent where it would be massively cruel not to end life in order to prevent suffering which is in no other way preventable.Where, however, the human individual is not a person, as is the case with abortion, the death of infants like Mary , or in the very rare and extreme cases of those who have ceased to be persons like Tony Bland, such decisions are governed by the ethics of ending the lives of non-persons.

This paper explores the relationship of mourning and the gift in the work of Jacques Derrida. I argue that mourning is not a Derridean gift, but mourning does open us to the gift. Reading the works of Aristotle, Cicero, and Kierkegaard on friendship and love to the dead in the wake of Derrida’s Politics of Friendship makes this relation among mourning and the gift apparent for he presents mourning as the opening to a democracy to-come whose logic is the gift. (...) Through these accounts, I maintain that in preparing us for the gift, mourning the dead other can help us to relate better with the living other in ethical, political, and ontological terms.

Cadaver organs should be automatically availableThe shortage of donor organs and tissue for transplantation constitutes an acute emergency which demands radical rethinking of our policies and radical measures. While estimates vary and are difficult to arrive at there is no doubt that the donor organ shortage costs literally hundreds of thousands of lives every year. “In the world as a whole there are an estimated 700 000 patients on dialysis . . .. In India alone 100 000 new patients present (...) with kidney failure each year” . Almost “three million Americans suffer from congestive heart failure . . . deaths related to this condition are estimated at 250 000 each year . . . 27 000 patients die annually from liver disease . . .. In Western Europe as a whole 40 000 patients await a kidney but only . . . 10 000 kidneys”1 become available. Nobody knows how many people fail to make it onto the waiting lists and fail to register in the statistics. “As of 24th November 2002 in the United Kingdom 667 people have donated organs, 2055 people have received transplants, and 5615 people are still awaiting transplants.”2Conscious of the terrible and unnecessary tragedy that figures like these represent I have been advocating for more than 20 years now some radical measures to stem this appalling waste of human life. The measure which is the subject of Hamer and Rivlin’s paper 3 concerns the automatic availability of all cadaver organs—a measure, which I first advocated publicly in 1983.4THE AUTOMATIC AVAILABILITY OF DONOR ORGANSWe need to begin by being clear about just what it is I propose and why.

The article explores an aspect of spiritual intelligence characterized as a lifelong search for meaning. Slow knowing involves wrestling with perplexity. Periods of such tarrying gradually facilitate an unfolding of meaning. More than just the content of one's knowledge, it is the relationship, the how or manner of one's relationship with meaning that grounds the spiritual generativity of the seeking. Slow knowing is presented as an existential orientation, a lifelong process akin to ongoing conversion. Part 1 distinguishes such slow knowing (...) from other senses of slow in current discourse (Kahneman's fast/slow thinking framework, and meditative concepts of slow mind). Part 2 explores slow knowing through the lenses of lectio divina and the use of metaphor in religious language. Slow knowing is characterized as having both individual and social dimensions. The article concludes with the concern that the conditions needed for slow knowing—and thus for spiritual intelligence—are undermined by the hasty pace of contemporary life. (shrink)

The article explores the interaction of verbal and nonverbal semantic levels in the performance of Christian ritual. The article maps the distinction between theoretical and performative knowledge onto Barnard and Teasdale's Interacting Cognitive Systems model to give a (partial) account of how meaning emerges in ritual participation. With Christian ritual, both know-how and know-that are needed. Above all, it is their interaction that generate the richness of meaning in ritual performance. Three core claims are made. First, many contemporary concepts of (...) ritual have at least one flaw in that they do not grasp the relationality between verbal and nonverbal, wherein both dimensions have a semantic integrity of their own. Second, there is an ideological valuation of the semantic levels. The experiential level is not only meaningful in its own right, but the fundamental ground of spiritual knowing. Third, combining learning styles and kinds of attention can be valuable for eliciting the full semantic richness of ritual participation. (shrink)

This introductory article to the thematic section on “Spiritual Intelligence” sets out the ways in which spiritual intelligence is currently conceptualized. Most prominently, spiritual intelligence is understood as an adaptive intelligence which enables people to develop their values, vision, and capacity for meaning. Questions arise as to whether spiritual intelligence is a distinct form of intelligence, and how to frame it if it is. It is questionable whether psychometric approaches justify concluding there is a distinct spiritual intelligence, and the authors (...) reject any notion of a God spot in the brain specifically dedicated to spiritual intelligence, which is a much more broadly embodied phenomenon. The authors suggest that spiritual intelligence most likely makes use of existing cognitive architecture, though applied in a distinctive way. This article finishes with a brief introduction to the four main articles in this thematic section, which present spiritual intelligence as a kind of participation in transcendent being. The four articles approach the cognitive, embodied, meditative, and ritual aspects of spiritual intelligence as participation. (shrink)

This article explores three aspects of Masterman's language work and applies them to questions of spiritual intelligence: metaphor, coherence, and ambiguity. First, metaphor, which is ubiquitous in ordinary language, both leads and misleads in religious and scientific understanding. Masterman's case for a “dual-approach” to thinking, both speculative and critical, is explored and tied to concepts of moral-spiritual development per Pierre Hadot and Hannah Arendt. Second, Masterman's work on machine translation presents semantic disambiguation as an emerging coherence wherein one gradually hones (...) in on meaning through features of ordinary language (like redundancy and repetition). This is applied to the problem of comprehending difficult spiritual language, and tied to spiritual stretching and spiritual cartography. Third, Masterman's work with thesauri, rather than relying on words as having fixed meanings, appeals to a concept of semantic spaces, nebulae of variously interconnected meanings. This is constructed into an exhortation to reambiguate overfamiliar religious language, to reinvest one's quotidian surroundings with spiritual meaning through defamilarization. (shrink)

:The term “moral bioenhancement” conceals a diverse plurality encompassing much potential, some elements of which are desirable, some of which are disturbing, and some of which are simply bland. This article invites readers to take a better differentiated approach to discriminating between elements of the debate rather than talking of moral bioenhancement “per se,” or coming to any global value judgments about the idea as an abstract whole. Readers are then invited to consider the benefits and distortions that come from (...) the usual dichotomies framing the various debates, concluding with an additional distinction for further clarifying this discourse qua explicit/implicit moral bioenhancement.

BackgroundDepressive disorders are a common form of psychiatric illness and cause significant disability. Regulation authorities, the medical profession and the public require high safety standards for antidepressants to protect vulnerable psychiatric patients. Ketamine is a dissociative anaesthetic and a derivative of a hallucinogen. Its abuse is a major worldwide public health problem. Ketamine is a scheduled drug and its usage is restricted due to its abuse liability. Recent clinical trials have reported that ketamine use led to rapid antidepressant effects in (...) patients suffering from treatment-resistant depression. However, various flaws in study designs, and possible biased reporting of results, may have influenced those findings. Further analyses of ketamine use are needed to ensure patient safety.DiscussionThe use of ketamine in research and treatment of depressive disorders is controversial. Recently, mental health professionals raised ethical concerns about an ongoing ketamine trial in the UK. Also, a Canadian agency reviewed the existing evidence and did not recommend prescribing ketamine to treat depressive disorders. Findings obtained from tightly controlled research settings cannot be easily translated to clinical practice as substance abuse is commonly comorbid with depressive disorders. An effective antidepressant should reduce severity of depressive symptoms without liability problems. Although the US FDA has not approved the use of ketamine to treat depressive disorders, some psychiatrists offer off-label repeat prescription of ketamine. Prescribing ketamine for treating depressive disorders requires substantial empirical evidence. Clinicians should also consider research findings on ketamine abuse. Depressive disorders can be chronic conditions and the current evidence does not rule out the risk of substance abuse after repeat prescription of ketamine. Off-label ketamine use in treating depressive disorders may breach ethical and moral standards, especially in countries seriously affected by ketamine abuse. This article presents two real-world clinical vignettes which highlight ethical principles and theories, including autonomy, nonmaleficience, fidelity and consequentialism, as related to off-label ketamine use.ConclusionWe urge clinicians to minimise the risk of harming patients by considering the empirical evidence on ketamine properties and attempting all standard antidepressant therapies before considering the off-label use of ketamine.

The panic occasioned by the birth of Dolly sent international and national bodies and their representatives scurrying for principles with which to allay imagined public anxiety. It is instructive to note that principles are things of which such people and bodies so often seem to be bereft. The search for appropriate principles turned out to be difficult since so many aspects of the Dolly case were unprecedented. In the end, some fascinating examples of more or less plausible candidates for the (...) status of moral principles were identified; central to many of them is the idea of human dignity and how it might be affected by human mitotic reproduction.

The question of whether or not either elderly people or those whose life expectancy is short have commensurately reduced claims on their fellows, have, in short, fewer or less powerful rights than others, is of vital importance but is one that has seldom been adequately examined. Despite ringing proclamations of justice and equality for all, the fact is that most societies discriminate between citizens on the basis both of age and life expectancy.

The chapter will argue that the way current enthusiasm for moral enhancement is articulated in the extant literature is itself morally problematic. The moral evaluation of the discourse will proceed through three stages. First, we shall look at the chequered history of various societies’ attempts to cast evil, character, and generally undesirable behaviour, as biological problems. As will be argued, this is the larger context in which moral enhancement discourse should be understood, and abuses in the recent past and present (...) should therefore be highlighted. Second, it will be argued that, given moral functioning's profoundly contextual and responsive qualities, any notion of a fine-grained, powerfully efficacious moral enhancement is both unrealistic and, actually, incoherent. Since enthusiasts’ hopes are unrealistic and incoherent, such enhancement would not even be capable of providing the transformative ends that supposedly justify the sometimes extreme prescriptions set forward. Finally, the chapter concludes with the claim that moral enhancement enthusiasm actually serves to trivialise the evils of this world, and not only to trivialise the hard-won efforts required to diminish and overcome such evils, but to misdirect attention away from the real hard work that needs to be done in facing such evils.

Sex is not the answer to everything, though young men think it is, but it may be the answer to the intractable debate over the ethics of human embryonic stem cell research. In this paper, I advance one ethical principle that, as yet, has not received the attention its platitudinous character would seem to merit. If found acceptable, this principle would permit the beneficial use of any embryonic or fetal tissue that would, by default, be lost or destroyed. More important, (...) I make two appeals to consistency, or to parity of reasoning, that I believe show that no one who either has used or intends to use sexual reproduction as their means of procreation, nor indeed anyone who has unprotected heterosexual intercourse, nor anyone who finds in vitro fertilization acceptable, nor anyone who believes that abortion is ever permissible can consistently object on principle to human embryo research nor to the use of embryonic stem cells for research or therapy.

Word recognition is the Petri dish of the cognitive sciences. The processes hypothesized to govern naming, identifying and evaluating words have shaped this field since its origin in the 1970s. Techniques to measure lexical processing are not just the back-bone of the typical experimental psychology laboratory, but are now routinely used by cognitive neuroscientists to study brain processing and increasingly by social and clinical psychologists (Eder, Hommel, and De Houwer 2007). Models developed to explain lexical processing have also aspired to (...) be statements about the nature of human cognition (e.g., connectionist models, Plaut, McClelland, Seidenberg, and Patterson 1996). Words were convenient objects to study for cognitive psychologists because they are welldefined and their nature as alphabetic strings was a good fit to analysis with the computer programming languages of the 1970s and 1980s which excelled at string manipulation. But are words actually the privileged unit of mental representation and processing that all of this scientific attention makes them out to be? Like a growing number of other language researchers, our answer is no (see, e.g., (Bybee and Hopper 2001; Wray 2002). We propose that the mental representations for lexical structures form a continuum, from word combinations which have fossilized into single units (nightclub) to those that both exist as independent units and yet have bonds, varying in tightness, with the words with which they frequently co-occur (Harris 1998). The first line of support for this view is the simple observation that fluent speakers easily recognize the familiarity and cohesive quality of word combinations in their language. Examples in English include common noun compounds (last year, brand new), verb phrases (cut down, get a hold of, faced with) and other multi-word expressions such as common sayings and references to cultural concepts (saved by the bell, speed of light; Jackendoff 1995)..

In this book Harris intends to construct an agent-centered conception of morality grounded on a naturalistic understanding of practical reason. In order to achieve this goal, he contrasts his Aristotelian revisionist perspective with the traditional and internalist Kantian proposals, focusing on two specific matters: the opposition between agent-centered and agent-neutral norms, and the newer and very interesting discussion of symmetrical versus asymmetrical regulative norms. The first topic will be especially relevant for the rejection of traditional Kantianism, while the second (...) will be the main argument against Kantian internalism. The author defends the thesis that some nouns have priority in some contexts and not in others against the context-insensibility of Kantian theories. In particular, giving a fair account of them and plenty of detailed argument to refute some of their aspects, he discusses Barbara Herman’s, Marcia Baron’s, Nancy Sherman’s, David Cummiskey’s, Christine Kosgaard’s, and John Rawls’s proposals.

Philosophers of history in the past few decades have been predominantly interested in issues of explanation and narrative discourse. Consequently, they have focused consistently and almost exclusively on the historian’s output, thereby ignoring that historical scholarship is a practice of reading, thinking, discussing, and writing, in which successful performance requires active cultivation of certain skills, attitudes, and virtues. This paper, then, suggests a new agenda for philosophy of history. Inspired by a “performative turn” in the history and philosophy of science, (...) it focuses on the historian’s “doings” and proposes to analyze these performances in terms of epistemic virtue. It argues that historical scholarship is embedded in “practices” or “epistemic cultures,” in which knowledge is created and warranted by means of such virtues as honesty, carefulness, accuracy, and balance. These epistemic virtues, however, are not etched in stone: historians may highlight some of them, exchange one for another, or reinterpret their meaning. On the one hand, this suggests a rich area of research for historians of historiography. To what extent can consensus, conflict, continuity, and change in historical scholarship be explained in terms of epistemic virtue? On the other hand, the proposal outlined in this article raises a couple of philosophical questions. For example, on what grounds can historians choose among epistemic virtues? And what concept of the self comes with the notion of virtue? In addressing these questions, philosophy of history may expand its current scope so as to encompass not only “writings” but also “doings,” that is, the virtuous performances historians recognize as professional conduct.
