Most early studies of consciousness have focused on human subjects. This is understandable, given that humans are capable of reporting accurately the events they experience through language or by way of other kinds of voluntary response. As researchers turn their attention to other animals, “accurate report” methodologies become increasingly difficult to apply. Alternative strategies for amassing evidence for consciousness in non-human species include searching for evolutionary homologies in anatomical substrates and measurement of physiological correlates of conscious states. In addition, creative (...) means must be developed for eliciting behaviors consistent with consciousness. In this paper, we explore whether necessary conditions for consciousness can be established for species as disparate as birds and cephalopods. We conclude that a strong case can be made for avian species and that the case for cephalopods remains open. Nonetheless, a consistent effort should yield new means for interpreting animal behavior.

Scientists and policy‐makers have long understood that the products of research can often be used for good or evil. Nuclear fission research can be used to generate electricity or create a powerful bomb. Studies on the genetics of human populations can be used to understand relationships between different groups or to perpetuate racist ideologies. While the notion that scientific research often has beneficial and harmful uses has been discussed before, the threat of bioterrorism—a concern that has only grown since 2001—has (...) led to increased awareness about the need to prevent the misuse of biomedical research, particularly when it involves dangerous pathogens or toxins. In 2012, the concern was ratcheted up another notch by two papers reporting the results of research on genetically engineered strains of the H5N1 avian influenza virus. Although the H5N1 papers have potential scientific and social value, some scientists and policy‐makers opposed their publication because they feared that terrorists (or others with nefarious motives) could use the research to create a bioweapon that could trigger a global pandemic. The H5N1 papers raise difficult questions concerning the ethics of knowledge. Should scientific research with dangerous applications be published? Should some types of research be kept secret or not be conducted at all? What type of government oversight of dangerous research is appropriate? In this essay, I will develop a framework for thinking about the ethics of knowledge and apply it to the H5N1 controversy, focusing on issues related to publication. I will argue that redacted publication would have been a reasonable response to the dilemmas posed by the H5N1 papers if not for practical and legal problems with this option. Given these problems, full publication seems appropriate. (shrink)

Hylomorphism offers a third way between animalist approaches to personal identity, which maintain that psychology is irrelevant to our persistence, andneo-Lockean accounts, which deny that humans are animals. This paper provides a Thomistic account that explains the intuitive responses to thought experiments involving brain transplants and the transformation of organic bodies into inorganic ones. This account does not have to follow the animalist in abandoning the claim that it is our identity which matters in survival, or countenance the puzzles of (...) spatially coincident entities that plague the neo-Lockean. The key is to understand the human being as only contingently an animal. This approach to our animality is one that Catholics have additional reason to hold given certain views about purgatory, our uniqueness as free and rational creatures, and our having once existed as zygotes.

The American Philosophical Association suggests that studying philosophy can have an important impact on one's creative thinking ability. This paper abstracts from the empirical research on creativity a reasonable model of creative thinking, and discusses what the account implies about fostering creative thinking in philosophy courses. Given the empirical research on creativity and the nature of philosophy, studying philosophy can have an important impact on one's creative thinking ability, but faculty need to focus on it in their courses.

This essay provides a rationale for a regulated market for human oocytes. Although the commodification of human oocytes raises important moral concerns, these concerns do not justify laws banning commerce in human eggs. Given the burgeoning ART industry and the growing oocyte market, the most prudent course of action is to develop regulations for the human oocyte market that are designed to protect and promote important social values, such as health, safety, liberty, and respect for human life. Other responses, such (...) as banning the sale of eggs altogether or allowing donors to be compensated only for their services, would either create a black market or would lead to corruption and abuse. Society still needs to debate specific rules and policies that should govern the human egg market, but further discussion of that important task is best left to legislative bodies and other commentators.

This paper examines how the faith/reason discussion can be expanded by means of culture and analogous language. The author argues that rationaldialogue can occur between different faith traditions, and without having to raise reason to the ideal of enlightenment objectivity or having to jettison reasonthrough some form of relativism. He argues that cultural shifts effect alterations in our very “criteria of rationality” so that our efforts to grasp others’ practices inmatters that challenge our presumed categories often reveal lacunae in our (...) very own presumptions. The author further argues that a prerequisite for dialogue isa shared interest in pursuing the truth; thus the pursuit of truth transcends any given conceptuality. Accordingly, rationality can show itself in practices that canbe followed and understood by persons operating on the basis of different grounding convictions. (shrink)

In their feature article, ‘Moral uncertainty and the farming of human-pig chimeras,’ Koplin and Wilkinson argue that there is a tension between thinking that creating pig-human chimaeras with partly humanised brains as a source of organs for transplantation as morally problematic because of the uncertainty of their moral status and thinking that the raising normal pigs for food is not morally problematic because of the certainty concerning their moral status.1 Koplin and Wilkson claim that the reasons that we are uncertain (...) about the moral status of human-pig chimaeras with partly humanised brains also apply to normal pigs. Our moral uncertainty derives from philosophical uncertainty concerning the characteristics that convey moral status and epistemological uncertainty concerning the extent to which pigs with partly humanised brains or normal pigs possess such characteristics. If we think it is morally problematic to create pigs with humanised brains for organ transplantation, we should also think it is morally problematic to raise normal pigs for food, given our uncertainty about the moral status of both kinds of animals. Their view implies that it would be inconsistent to have moral qualms about creating pigs with humanised brains for organ transplantation but to no such misgivings about raising pigs for food. While I find Koplin and Wilkson’s arguments …. (shrink)

Sometimes researchers explicitly or implicitly conceive of authorship in terms of moral or ethical rights to authorship when they are dealing with authorship issues. Because treating authorship as a right can encourage unethical behaviours, such as honorary and ghost authorship, buying and selling authorship, and unfair treatment of researchers, we recommend that researchers not conceive of authorship in this way but view it as a description about contributions to research. However, we acknowledge that the arguments we have given for this (...) position are largely speculative and that more empirical research is needed to better ascertain the benefits and risks of treating authorship on scientific publications as a right.

Openness is one of science’s fundamental ethical norms, but it should not take precedence over the obligation to protect the confidentiality of data. Deidentifying the data obtained from human genomic research as a condition of providing open access to research data is a strategy to promote scientific openness while protecting research participants’ confidentiality interests. However, given recent advances in methods of reidentifying individuals whose deidentified data are in genomic databases, the best way to balance scientific openness and protection of human (...) subjects in genomic research is to permit access to genomic data on a restricted basis.

We consider the following question within both Newtonian physics and relativity theory. "Given two point particles X and Y, if Y is rotating relative to X, does it follow that X is rotating relative to Y?" As it stands the question is ambiguous. We discuss one way to make it precise and show that, on that reading at least, the answers given by the two theories are radically different. The relation of relative orbital rotation turns out to be symmetric in (...) Newtonian physics, but not in relativity theory. (shrink)

In summary, the question of how to construe the procedure called reversibility cannot be given an absolute answer. No one moral interpretation of the principle is universally applicable, that is, applicable to all moral issues. The decision concerning which to apply cannot be made a priori, but only in context - that is, only when we are faced with a particular moral problem. Moreover, there appears to be no rule which would enable us to choose which version is correct in (...) a particular case. It is a matter of judgment.That the various versions represent a moral progression from lower to higher constructions is debatable. We have seen that the altruism of reversibility3 - the ethic of care - may recommend itself in some personal relations to the point of making either version of reversibility4 irrelevant. Similarly, it is not clear that reversibility3 is always higher than reversibility2. For example, parents in trying to decide what is morally best for a young child should often - in the spirit of the second construction - substitute the judgment of their mature selves for the judgment of the immature self of the child. Moreover, this substitution may not be justifiable in terms of either utility or autonomy.If I seem to have ignored reversibility1 in this discussion that is because I consider it outside morality: it is, if anything, a principle of self-interested calculation. If Baier is correct in holding that we teach children to think morally when we get them to take the standpoint of others, that requires, I believe, getting them beyond the stage of crude reciprocity. If Piaget and Kohlberg are correct in their developmental claims, we cannot immediately teach children reversibility4 but must help them progress through the other two versions. There is some basis for thinking that children can transcend egoism and sympathize with others much earlier than Kohlberg allows - an important consideration in the development of a system of moral education. That point has been pursued by Michael Pritchard in his critique of Kohlberg. Pritchard, p 44. My point is a different one: even granting Kohlberg's theory of development (which asserts, for example, that a particular cognitive ability is required to think like a Kantian), it does not follow that the moral thinking which accompanies the highest cognitive stage is morally superior to the moral thinking which accompanies the lesser cognitive stages. That it is cognitively easier to master reversibility3 than reversibility4 does not settle the question of which is morally superior. Rather than arguing about which moral version of reversibility is morally best- a pointless debate if the desirability of a version is understood as contingent upon appropriateness with respect to context - we should instead celebrate the richness of the concept of reversibility. In teaching students the moral point of view by getting them to put themselves in another's place, we would not be asking them to master a rigid formula, but rather to be sensitive to the decisional context and to make a thoughtful judgment about which version of reversibility is most appropriate to that context. We would not be teaching them either moral relativism or moral absolutism, but the complexity of trying to make a moral decision by applying an ancient and philosophically rich ethical principle.

In recent philosophical debates a number of arguments have been used which have so much in common that it is useful to study them as having a similar structure. Many arguments -- Searle's Chinese Room, for example -- make use of thought experiments in which we are told a story or given a narrative context such that we feel we are in comfortable surroundings. A new notion is then introduced which clashes with our ordinary habits and associations. As a result, (...) we do not bother to investigate seriously the new notion any further. I call such an arrangement, which is perhaps a variation of the fallacy of presumption, a Steep Cliff argument. One remedy for the misdirection of a Steep Cliff argument is to tell a counterstory from the point of view of the rejected notion. (shrink)

Hundreds of thousands of individuals experience traumatic injuries each year. Some are mild to moderate in nature and patients experience full functional recovery and little change to their physical appearance. Others result in enduring, if not permanent, changes in physical functioning and appearance. Reconstructive plastic surgical procedures are viable treatments options for many patients who have experienced the spectrum of traumatic injuries. The goal of these procedures is to restore physical functioning and reduce the psychosocial burden of living with an (...) appearance that may be viewed negatively by the patient or by others. Even after receipt of reconstructive procedures, many patients are left with residual disfigurement. In some, disability and disfigurement may be so profound that individuals are candidates for vascularized composite allotransplantation procedures, i.e., the transplantation of a vascularized human body part containing multiple tissue types as an anatomical and/or structural unit. This narrative review paper summarizes the literature on the psychosocial burden experienced by those who have visible disfigurement. While many of these individuals experience stigma and discrimination, relatively few studies have employed a stigma framework to understand the psychosocial sequelea. This paper briefly addresses this framework. Last, particular focus is given to the psychosocial issues of individuals with particularly severe injuries who are potential candidates for VCA procedures. (shrink)

As a result of financial difficulties confronting American agriculture, public debate is focusing on longterm options for restoring economic stability and growth to the agricultural economy. Many believe that just as homeowners in small communities throughout the nation have been served by the development of a secondary market for residential mortgages sponsored by the federal government, farmers throughout the country would similarly benefit from the development of a secondary market for farm real estate mortgages. This paper discusses issues relating to (...) the development of a secondary market for agricultural real estate loans. The concept of a secondary market for agriculture is of considerable interest to Congress, as evidenced by recent enactment of the Agricultural Credit Act of 1987 which established the Federal Agricultural Mortgage Corporation (“Farmer Mac”) to create a secondary market for farm real estate loans. The first section discusses the general nature of secondary markets and their purposes, with particular attention given to the secondary market for home mortgages because it served as a model for a secondary market for farm loans. Section two discusses basic differences between agriculture and housing, and section three provides a brief discussion of federal credit subsidies designed to help meet social and economic goals by influencing the allocation of credit to particular sectors of the economy such as housing and agriculture. Potential benefits and costs associated with the development of a secondary market for agriculture are discussed in section four. (shrink)

Lately, the attitude of philosophers generally toward the free will issue has taken what I regard as an inauspicious turn. Where the predominant opinion had been that determinism and freedom were at harmony with one another, today it is incompatibilism which seems to prevail, and new voices raised in defense of libertarianism now offer their promise that problems once thought prohibitive to an acceptance of contra-causal freedom might be surmounted. I shall attempt to show that this recent rejection of compatibilism (...) in fact rests on a mistake, and I shall suggest the outline of a solution to the free will issue which reconciles determinism and freedom.We shall say that an event is nomologically necessary if and only if given a specified set of conditions and the actually existing laws of nature, the statement of that event could in principle be deduced as the conclusion of a valid deductive argument having the statement of initial conditions and the statement of the relevant law as premises.

This article explores the rhetoric of violence in the Buddhist tantras, arguing that it generally falls into two types: violence deployed in a purely rhetorical fashion for the purpose of impressing or persuading the reader; and textual depictions of violent ritual practices, which can, with some caveats, be interpreted as depictions of, and possibly prescriptions for, ritual violence. The former type often includes grandiose or exaggerated instances of hyperbolic rhetoric, often deployed for the purpose of aggrandizing the text or tradition. (...) The article segues to discussions of descriptions of and prescriptions for ritual violence, and explores one of the justifications given for ritual violence, namely that it contributes to, or is excused by, the attainment of a spiritually advanced state of awareness called the “non-dual gnosis”. Here particular attention is paid to violent rituals that involve the creation of effigies or symbolic substitutes for a sacrificial victim. These rituals, rather than involving actual violence, instead symbolically depict it. Yet these rituals are still violent insofar as they are symbolic enactments of acts of violence, and often they are performed with the goal of actually harming the victim who is symbolically represented in the ritual practice. The article concludes with an examination of a strategy for legitimizing such violence by invoking the concept of non-dual gnosis, and suggests that this ethical double standard has actually been used to excuse ethically dubious conduct by contemporary Buddhist leaders.

The objective of the article is twofold: to advance an interpretation of Descartes’ position on the problem of explaining how deduction from universal propositions to their particular instances can be both legitimate and useful for discovery of truth; and to argue that his position is a valuable contribution to the philosophy of logic. In Descartes’ view. the problem in question is that syllogistic deductions from universal propositions to their particular instances is circular and hence useless as a means for discovery (...) of truth. Descartes’ solution to the problem is to claim that noncircular, useful deduction from the universal to the particular must first be based on deduction from particular truths to particular truths. I examine previous interpretations of Cartesian deduction given by E.M. Curley, Bernard Williams, and Andre Gombay. None of these interpretations fit with all of Descartes’ criticisms of syllogistic deduction and his characterization of useful and legitimate deduction (such as the cogito). I argue that the key to a correct interpretation is Descartes’ claim that implicit knowledge of universal propositions plays a crucial role in useful and legitimate deduction, and I explain how we may cash in his talk of implicit knowledge through Ryle’s notion of knowing how. Having set out a fuller explication of Descartes’ theory of deduction, I argue that it is consistent with the way people actually reason, that it helps us with problems in the philosophy of logic that have been raised by John Stuart Mill, Hilary Putnam, and Michael Dummett.

This work offers a bold and illuminating exercise in philosophy as narrative, and in doing so presents itself quite consciously as an alternative mode of explanation to the "rationalist paradigm" which dominated Greek philosophy. Yet while acknowledging the inspiration of Hegel, the work hews far more closely than the author of Phänomenologie des Geistes to the actual dialectic of explanation as it worked itself out from Aristotle through Plotinus to Aquinas--to mention only the most prominent milestones. In that respect, the (...) book offers an apparently independent and certainly more lyrical orchestration of the themes elaborated in such careful counterpoint by Edward Booth in his Aristotelian Aporetic Ontology in Islamic and Christian Writers. Indeed, for each author, it is a stubborn aporia inherent in Aristotle's project, yet resistant to resolution in terms of that same project, which fuels the resultant "historical dialectic." Booth's formulation focuses on the metaphysical clash between Aristotle's assertion that existing individuals bear ontological primacy and his insistence that form alone is intelligible, however, while Madigan pinpoints the explanatory lacuna in the project of Aristotle's Metaphysics as he intended it to complete the Physics. Yet I would suggest that these two formulations manifest a single metaphysical impasse for Aristotle; in fact, the very one which was to come to the fore in the debate which emerged within Islamic, Jewish, and Christian philosophical theology regarding the origins of the universe. As Madigan summarizes it: "a theory of creation or the production of the world through efficient causality is necessary to explain the world, or to render Aristotle's system complete. This is what Plotinus' philosophy lacked. But given creation or the free production of an independent world, a theory of salvation is necessary to make creation itself for the first time rational".

In Truthfulness and Tragedy Stanley Hauerwas provides an account of moral existence and ethical rationality that shows how Christian convictions operate, or should operate, to form and direct lives. In attempting to conceptualize the basis of Christian ethics in a manner that will render Christian convictions morally intelligible, the author casts fresh light on traditional theoretical issues and articulates the distinctive Christian response to contemporary concerns such as suicide, medical ethics, and child care. The first section of the book deals (...) with methodological issues: the meaning and nature of practical reason, obligation claims, natural law, and self deception, and the affinity of story and ethics. It focuses on the relation of truthfulness and tragedy and the need for a story--a set of religious convictions or "grammar of theology"--that does justice to the tragic character of human existence. The second section addresses substantive issues: suicide, euthanasia, and the value of survival; the moral limits of population growth; the definition of "person" for medical reasons; and social involvement and Christian ethics. The overall theme is the need for a community in which truthfulness is a way of life. In the final section, devoted to the problem of how to care for retarded children, the implications of the author's ethical position are given concrete expression. He discusses the assumptions underlying the willingness to have children, criteria for humanness, medical ethics, and how truthful communities deal with suffering. In Truthfulness and Tragedy Stanley Hauerwas extends and clarifies the ethical position set forth in his earlier books Character and the Christian Life and Vision and Virtue. He is associate professor of theology at the University of Notre Dame. He was a senior fellow in Christian medical ethics at the Joseph and Rose Kennedy Institute for the Study of Reproduction and Bioethics, and taught medical ethics at the University of Texas medical branch in Galveston.

We introduce a framework that can be used to model both mathematics and human reasoning about mathematics. This framework involves stochastic mathematical systems (SMSs), which are stochastic processes that generate pairs of questions and associated answers (with no explicit referents). We use the SMS framework to define normative conditions for mathematical reasoning, by defining a “calibration” relation between a pair of SMSs. The first SMS is the human reasoner, and the second is an “oracle” SMS that can be interpreted as (...) deciding whether the question–answer pairs of the reasoner SMS are valid. To ground thinking, we understand the answers to questions given by this oracle to be the answers that would be given by an SMS representing the entire mathematical community in the infinite long run of the process of asking and answering questions. We then introduce a slight extension of SMSs to allow us to model both the physical universe and human reasoning about the physical universe. We then define a slightly different calibration relation appropriate for the case of scientific reasoning. In this case the first SMS represents a human scientist predicting the outcome of future experiments, while the second SMS represents the physical universe in which the scientist is embedded, with the question–answer pairs of that SMS being specifications of the experiments that will occur and the outcome of those experiments, respectively. Next we derive conditions justifying two important patterns of inference in both mathematical and scientific reasoning: (i) the practice of increasing one’s degree of belief in a claim as one observes increasingly many lines of evidence for that claim, and (ii) abduction, the practice of inferring a claim’s probability of being correct from its explanatory power with respect to some other claim that is already taken to hold for independent reasons.

318 JOURNAL OF THE HISTORY OF PHILOSOPHY 36:2 APRIL 1998 stress should not be placed on Spinoza's excommunication . One among many who held radical views and during a period of unrest brought on by an influx of emigration, Spinoza was dealt the same punishment as those who failed to pay their communal dues. The apt conclusion drawn is that from the perspective of the commu- nity, this excommunication was of no great significance. Such history corrects earlier interpretations and helps (...) readers to approach primary texts through the introduction of the problems and issues of the specific period. Devoting almost six hundred pages to ancient and medieval philosophy, the last third of the history is given over to modern and contemporary thought. Seymour Feldman's clear account of Spinoza sets the tone for Michael L. Morgan's presentation of Mendelssohn and Mordecai Finley's account of German Reform philosophy. Both represent stages in the accommodation of Judaism to the Enlightenment. What is important to keep in mind here and what becomes clear in the text is that Jewish philosophers were not just appropriators of the Enlightenment, but played central roles in its formation. Harry Lesser and David Ellenson present the other side of the story through balanced accounts of the emergence of Jewish Orthodoxy as a response to Reform philosophy. Continuing where Julius Guttmann left off in his classic history translated as Philoso- phies of Judaism.. (shrink)

The hereditary neurodegenerative disease spinal muscular atrophy (SMA) with childhood onset is one of the most common genetic causes of infant mortality. The disease is characterized by selective loss of spinal cord motor neurons leading to muscle atrophy and is the result of mutations in the survival motor neuron (SMN) gene. The SMN protein has been implicated in diverse nuclear processes including splicing, ribosome formation and gene transcription. Even though the genetic basis of SMA is well understood, it is not (...) clear how defects in these ubiquitous processes result in motor neuron degeneration leaving other tissues unaffected. Recent evidence from animal and cell culture models of SMA points to roles for SMN in neurite outgrowth and axonal transport. Disruption of these functions might be particularly detrimental to motor neurons given their high metabolic demands and precise connectivity requirements, thus providing a possible explanation for the specificity of motor neuron susceptibility in SMA. Understanding the molecular mechanisms of SMN activity in neuronal processes may generate new targets for future therapeutic strategies. BioEssays 27:946–957, 2005. © 2005 Wiley Periodicals, Inc.

The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sample of 795 US Americans to evaluate the moral status of psilocybin use in an appropriately licensed setting for either treatment of a psychiatric condition or well-being enhancement. (...) Showing strong bipartisan support, participants rated the individual’s decision as morally positive in both contexts. These results can inform effective policy-making decisions around supervised psilocybin use, given robust public attitudes as elicited in the context of an innovative regulatory model. We did not explore attitudes to psilocybin use in unsupervised or non-licensed community or social settings. (shrink)

An experiment was performed to test the hypothesis that people sometimes take physical actions to make themselves more effective problem solvers. The task was to generate all possible words that could be formed from seven Scrabble letters. In one condition, participants could use their hands to manipulate the letters, and in another condition, they could not. Results show that more words were generated with physical manipulation than without. However, an interaction was obtained between the physical manipulation conditions and the specific (...) letter sets chosen, indicating that physical manipulation helps more for generating words in some circumstances than in others. Overall, our findings can be explained in terms of an interactive search process in which external, physical activity effectively complements internal, cognitive activity. Within this framework, the interaction can be explained in terms of the relative difficulty of generating words from the letters given in the different sets. (shrink)

Status anxiety, the constant concern about individuals’ position on the social ladder, negatively affects social cohesion, health, and wellbeing. Given previous findings showing that status anxiety is associated with economic inequality, we aimed in this research to test this association experimentally. A cross-sectional study was run in order to discard confounding effects of the relationship between perceived economic inequality and status anxiety, and to explore the mediating role of a competitive climate. Then we predicted that people assigned to a condition (...) of high inequality would perceive more status anxiety in their social context, and they would themselves report higher status anxiety. Thus, in an experimental study PEI was manipulated. In Study 1, PEI uniquely predicted status anxiety, and perceived competitiveness mediated the relationship. In Study 2 PEI increased perceived contextual status anxiety, a specific form of perceived competitiveness based on socioeconomic status. Moreover, preliminary evidence of an indirect effect was found from PEI to personal status anxiety, through perceived contextual status anxiety. These preliminary findings provide experimental evidence for the effects of economic inequality on status anxiety and the mechanism involved. Economic inequality makes people feel that they live in a society where they are constantly concerned and competing with each other for their SES. These results could have important implications as health and wellbeing could be promoted by reducing economic inequalities and the competitive and materialistic environments of our societies.

Time belongs to a handful of categories (like form, symbol, cause) that are genuinely transdisciplinary. Time touches every dimension of our being, every object of our attention - including attention itself. It therefore can belong to no single field of study. Of course, this universalist view of time is not itself universal but rather is a product of the modern age, an age that conceived of itself as the 'new' time. Time has thus gained new importance as a theme of (...) general research with the 'post-modern turn' now manifest in many areas of intellectual endeavor, especially in the humanities and social sciences. 'Chronotypes' are models or patterns through which time assumes practical or conceptual significance. Time is not given but (as the subtitle indicates) fabricated in an ongoing process. Chronotypes are themselves temporal and plural, constantly being made and remade at multiple individual, social, and cultural levels. They interact, they change over time, and they have histories, whose construal is itself an act of temporal construction. This book - an interdisciplinary collaboration of philosophers, historians, literary critics, and anthropologists - examines the ways individuals, societies, and cultures make sense of time by constructing it in diverse patterns. Its title intentionally echoes a concept of narrative theory, Mikhail Bakhtin's 'chronotype', because narrative recurs as a chief form within which we build temporality. The topics treated by these essays range from story-telling to cross-cultural communication, from epistemological debates to concepts of historical periodization, from the construction of life stories to the stratification of social time.

We study the structure of Σ11 equivalence relations on hyperarithmetical subsets of ω under reducibilities given by hyperarithmetical or computable functions, called h-reducibility and FF-reducibility, respectively. We show that the structure is rich even when one fixes the number of properly equation imagei.e., Σ11 but not equation image equivalence classes. We also show the existence of incomparable Σ11 equivalence relations that are complete as subsets of ω × ω with respect to the corresponding reducibility on sets. We study complete Σ11 (...) equivalence relations and show that existence of infinitely many properly Σ11 equivalence classes that are complete as Σ11 sets is necessary but not sufficient for a relation to be complete in the context of Σ11 equivalence relations.

Models carry the meaning of science. This puts a tremendous burden on the process of model selection. In general practice, models are selected on the basis of their relative goodness of fit to data penalized by model complexity. However, this may not be the most effective approach for selecting models to answer a specific scientific question because model fit is sensitive to all aspects of a model, not just those relevant to the question. Model Structural Adequacy analysis is proposed as (...) a means to select models based on their ability to answer specific scientific questions given the current understanding of the relevant aspects of the real world.

Brexit activists demonstrating outside the British Houses of Parliament were studied in situ to examine their potential for pro-group extreme behavior. This involved activists of two polarized, opposing views; those of Leave and Remain. The research engaged concepts linking the different theoretical perspectives of identity fusion and personal construct psychology. The study measured participants' degree of fusion to their group using a verbal measure. Willingness to undertake extreme acts was assessed in several ways: a measure of willingness to fight for (...) the group, adaptations of the trolley dilemma and questions regarding political violence. Individual construing was examined using repertory grid technique and a semi-structured interview. Results were similar for both Leave and Remain participants. The majority of activists identified as “fused” to their group and, if so, were more likely to undertake hypothetical extreme behavior compared to those who did not identify as “fused.” Repertory grid technique indicated that becoming an activist provided individuals with a clearer and more positive view of themselves. Opposition activists were construed more negatively and extremely than fellow activists, and this construal was associated with an increased willingness to undertake extreme pro-group behavior. This was consistent with the personal construct model of radicalization and was heightened in those who were “fused.” Interview data provided support for the constructivist model and revealed characteristics and concerns of the two groups. Overall, the findings indicate that campaigning organizations contain fused individuals, who are more likely to undertake hypothetical pro-group violence including self-sacrifice. This has broader implications which may be particularly pertinent, given the violent impact of extremist activists around the globe. (shrink)

We pose and resolve a puzzle about spontaneous symmetry breaking in the quantum theory of infinite systems. For a symmetry to be spontaneously broken, it must not be implementable by a unitary operator in a ground state's GNS representation. But Wigner's theorem guarantees that any symmetry's action on states is given by a unitary operator. How can this unitary operator fail to implement the symmetry in the GNS representation? We show how it is possible for a unitary operator of this (...) sort to connect the folia of unitarily inequivalent representations. This result undermines interpretations of quantum theory that hold unitary equivalence to be necessary for physical equivalence. (shrink)

We investigate introduction and elimination rules for truth-functional connectives, focusing on the general questions of the existence, for a given connective, of at least one such rule that it satisfies, and the uniqueness of a connective with respect to the set of all of them. The answers are straightforward in the context of rules using general set/set sequents of formulae, but rather complex and asymmetric in the restricted (but more often used) context of set/formula sequents, as also in the intermediate (...) set/formula-or-empty context.

In this paper, I present a new semantics for demonstratives. Now some may think that David Kaplan (1989a,b) has already given a more than satisfactory semantics for demonstratives, and that there is no need for a new one. But I argue below that Kaplan's theory fails to describe the linguistic meanings of 'that' and other true demonstratives. My argument for this conclusion has nothing to do with cognitive value, belief sentences, or other such contentious matters in semantics and the (...) philosophy of mind. Rather, it appeals to the obvious fact that there can be true utterances of certain sentences containing several occurrences of the same demonstrative (for instance, 'That is taller than that'). My argument can be answered by making a fairly modest revision in Kaplan's theory. But I believe that the resulting revised version of Kaplan's theory ignores or distorts various important semantic features of 'that'. Thus I ultimately argue in favor of a more substantial departure from Kaplan's theory. Perhaps the most remarkable feature of the theory I favor is that it ascribes three distinct sorts of meanings to demonstratives. (shrink)

In this paper, we inquire further into the question of the emergence of new orders in physics, first raised in an earlier paper. In this inquiry, we are led to suggest that the quantum theory indicates the need for yet another new order, which we call “enfolded” or “implicate.” One of the most striking examples of the implicate order is to be seen by considering the function of the hologram, which clearly reveals how a total content (in principle extending over (...) the whole of space and time) is “enfolded” in the movement of waves (electromagnetic and other kinds) in any given region. We then come to the notion that the quantum theory indicates that this implicate order is not merely a dependent or fortuitous feature of the content, but rather, that it should be considered as the independent ground of existence of things, while the ordinary explicate order is what should be considered as dependent. Finally, in the appendix we point out how the implicate order is expressed naturally in terms of an algebra similar to that of the quantum theory, which is, however, subject to generalizations going beyond the limits of what has meaning in this theory. Various new directions of further research are indicated, which will be explained in later papers. (shrink)

I address the problem of indefiniteness in quantum mechanics: the problem that the theory, without changes to its formalism, seems to predict that macroscopic quantities have no definite values. The Everett interpretation is often criticised along these lines, and I shall argue that much of this criticism rests on a false dichotomy: that the macroworld must either be written directly into the formalism or be regarded as somehow illusory. By means of analogy with other areas of physics, I develop the (...) view that the macroworld is instead to be understood in terms of certain structures and patterns which emerge from quantum theory (given appropriate dynamics, in particular decoherence). I extend this view to the observer, and in doing so make contact with functionalist theories of mind. (shrink)

This is a discussion of how we can understand the world-view given to us by the Everett interpretation of quantum mechanics, and in particular the role played by the concept of 'world'. The view presented is that we are entitled to use 'many-worlds' terminology even if the theory does not specify the worlds in the formalism; this is defended by means of an extensive analogy with the concept of an 'instant' or moment of time in relativity, with the lack of (...) a preferred foliation of spacetime being compared with the lack of a preferred basis in quantum theory. Implications for identity of worlds over time, and for relativistic quantum mechanics, are discussed. (shrink)

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use (...) in other populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.

The contextualist epistemological theories proposed by David Lewis and othersoffer a view of knowledge which awards a central role to the contexts ofknowledge attributions. Such contexts are held to determine how strong anepistemic position must be in order to count as knowledge. Lewis has suggestedthat contextualism so construed can be used both to ward off the skeptic and tosolve the Gettier problem. A person knows P, he says, just in case her evidenceeliminates every possibility that not-P, where the domain (...) of `every' is determinedby the context. Lewis provides a list of rules that can tell us, for a given context,which not-P possibilities must be eliminated and which can properly be ignored.But his account entails, counterintuitively, that knowledge can truly be attributedeven to a person in a Gettier situation provided only that the attributor is ignorantof the fact that the person is gettiered. It has been criticized on those grounds byS. Cohen. In this paper I shall argue that most other forms of contextualism sufferthe same fate as Lewis's. The allies of contextualism haven't yet shown us whethercontextualism can succeed in maintaining a notion of ordinary knowledge whileresisting the absurdity that knowledge can be a matter of sheer good luck. At theend of the paper I shall suggest a possible solution to the problem by showing howCohen's line of criticism leads to a modified conception of what sort of justificationa belief must have to count as knowledge in ordinary contexts.

During the past decade scientists, public policy analysts, politicians, and laypeople, have become increasingly aware of the importance of ethical conduct in scientific research. In this timely book, David B. Resnik introduces the reader to the ethical dilemmas and questions that arise in scientific research. Some of the issues addressed in the book include ethical decision-making, the goals and methods of science, and misconduct in science. The Ethics of Science also discusses significant case studies such as human and animal (...) cloning, the Challenger accident and Tobacco research. This is essential reading for anyone who wishes to understand the importance of ethics in science. (shrink)

This study presents a probabilistic model of melody perception, which infers the key of a melody and also judges the probability of the melody itself. The model uses Bayesian reasoning: For any “surface” pattern and underlying “structure,” we can infer the structure maximizing P(structure|surface) based on knowledge of P(surface, structure). The probability of the surface can then be calculated as ∑ P(surface, structure), summed over all structures. In this case, the surface is a pattern of notes; the structure is a (...) key. A generative model is proposed, based on three principles: (a) melodies tend to remain within a narrow pitch range; (b) note‐to‐note intervals within a melody tend to be small; and (c) notes tend to conform to a distribution (or key profile) that depends on the key. The model is tested in three ways. First, it is tested on its ability to identify the keys of a set of folksong melodies. Second, it is tested on a melodic expectation task in which it must judge the probability of different notes occurring given a prior context; these judgments are compared with perception data from a melodic expectation experiment. Finally, the model is tested on its ability to detect incorrect notes in melodies by assigning them lower probabilities than the original versions. (shrink)

Objective: To explore the relationship between pharmacists'' tenure in the community setting and their moral reasoning abilities. Design: Systematic random sample design. Setting: A large southeastern city in the United States. Participants:450 independent and chain community pharmacists identified from the state board of pharmacy list of licenced community pharmacists. Interventions: A mailed questionnaire that included a well-known moral reasoning instrument and collected demographic information. Main Outcome Measures: Moral Reasoning abilities and tenure of community pharmacists. Results: As a group, community pharmacists (...) with greater years of tenure in community practice scored significantly lower on moral reasoning than those pharmacists with fewer years of tenure (p = 0.016). Conclusion: Four plausible explanations for the results are given including: a) a selection of lower ethical reasoners and/or an exodus of higher ethical reasoners from the community setting; b) a retrogression in the moral reasoning skills as community pharmacists obtain tenure in this setting; c) differences between the low and high moral reasoning groups may be due to a cohort effect; and d) the obtained practitioner sample may not have been representative of the population of community pharmacists.

Consider an election in which each of the n voters casts a vote consisting of a strict preference ranking of the three candidates A, B, and C. In the limit as n→∞, which scoring rule maximizes, under the assumption of Impartial Anonymous Culture (uniform probability distribution over profiles), the probability that the Condorcet candidate wins the election, given that a Condorcet candidate exists? We produce an analytic solution, which is not the Borda Count. Our result agrees with recent numerical results (...) from two independent studies, and contradicts a published result of Van Newenhizen (Economic Theory 2, 69–83. (1992)). (shrink)

This is another contribution to the unending controversy over the two Barbaras. My approach to the problem is hopefully quite new: I wish to view the issue through the prism of modal upgrading. Modal upgrading occurs when a subject term that has only been predicated of assertorically in the premises is predicated of apodictically either: i) in the conclusion of a given syllogism, or; ii) in some proposition that is derived from either the premises of the given syllogism alone or (...) the premises in combination with other propositions that do not refer to the proposition’s subject term. I call the proposition after it has been upgraded the upgraded proposition. When a conclusion is the upgraded proposition, it is obviously a different predicate being predicated than was predicated in the premises. Aristotle endorses this kind of upgrading; it is effectively what happens in any valid mixed modal syllogism when the minor premise is not apodictic (e.g., Barbara LXL). In other cases the upgraded proposition is not a conclusion but still follows from the premises alone. In these cases it is the same predicate being predicated in the upgraded proposition as in the premises, although the quantity of the propositions are different (one is universal, another particular). Aristotle rejects this kind of upgrading and takes its occurrence as sufficient to deny the validity of the given syllogism (e.g., Barbara XLL). I will describe a third type where both the predicate remains the same and the quantity of the proposition remains the same as in the premise, e.g., the upgrading of “All C are B” to “All C are necessarily B”. In these cases it will turn out that the upgraded proposition is not derived from the premises alone, or at least, not syllogistically from the premises alone. This kind of upgrading too is reason for denying the validity of any syllogism from which the upgraded proposition follows as a consequence. I will show that Barbara LXL entails this kind of modal upgrading and should be rejected for this reason. Armed with this notion of modal upgrading I want to attack the problem of the two Barbaras in Aristotle’s apodictic syllogistic. Aristotle himself endorses mixed modal Barbara when the major is necessary and the minor is assertoric, thereby endorsing the first kind of modal upgrading, but rejects Barbara when the minor is necessary and the major is assertoric on the grounds that it leads to the second kind of modal upgrading. Theophrastus endorses the peioram rule which rejects both Barbaras on the grounds that the conclusion can only be as strong as the weakest premise. Łukasiewicz endorses both Barbaras. I will argue that both Barbaras lead to unacceptable modal upgrading and should be taken to be invalid for that reason. Hence, I agree with Theophrastus about the two Barbaras; however, I do not endorse the peioram rule because I think that the negative mixed modal syllogisms generally avoid this problem and is mostly correct.
