Larry Temkin famously argues that what he calls spectrum arguments yield strong reason to reject Transitivity, according to which the ‘all-things-considered better than’ relation is transitive. Spectrum arguments do reveal that the conjunctions of independently plausible claims are inconsistent with Transitivity. But I argue that there is very strong independent reason to reject such conjunctions of claims, and thus that the fact that they are inconsistent with Transitivity does not yield strong reason to reject Transitivity.

ABSTRACT I consider paradoxical spectrum arguments involving transitive relations like ‘better than’. I argue that, despite being formally different from sorites arguments, at least some spectrum arguments arise from vagueness, and that vagueness might often be the most natural diagnosis.

This article shows that introducing the positive comparative relation parity only helps one block so‐called “Spectrum Arguments” in order to avoid their unsavoury implications if one specifies parity in a specific way with respect to its persistence. The article illustrates how parity must both admit of persistency and be weakly non‐persistent for parity to block Spectrum Arguments, and identifies some consequences of that discovery for the general debate on Spectrum Arguments, value theory and comparability problems.

The spectrum argument purports to show that the better-than relation is not transitive, and consequently that orthodox value theory is built on dubious foundations. The argument works by constructing a sequence of increasingly less painful but more drawn-out experiences, such that each experience in the spectrum is worse than the previous one, yet the final experience is better than the experience with which the spectrum began. Hence the betterness relation admits cycles, threatening either transitivity or (...) asymmetry of the relation. This paper examines recent attempts to block the spectrum argument, using the idea that it is a mistake to affirm that every experience in the spectrum is worse than its predecessor: an alternative hypothesis is that adjacent experiences may be incommensurable in value, or that due to vagueness in the underlying concepts, it is indeterminate which is better. While these attempts formally succeed as responses to the spectrum argument, they have additional, as yet unacknowledged costs that are significant. In order to effectively block the argument in its most typical form, in which the first element is radically inferior to the last, it is necessary to suppose that the incommensurability is particularly acute: what might be called radical incommensurability. We explain these costs, and draw some general lessons about the plausibility of the available options for those who wish to save orthodox axiology from the spectrum argument. (shrink)

Formerly a spectral apparition that haunted behaviorism and provided a puzzle about our knowledge of other minds, the inverted spectrum possibility has emerged as an important challenge to functionalist accounts of qualia. The inverted spectrum hypothesis raises the possibility that two individuals might think and behave in the same way yet have different qualia. The traditional supposition is of an individual who has a subjective color spectrum that is inverted with regard to that had by other individuals. (...) When he looks at red objects, this individual has the qualia normally produced in others by blue objects. And when presented with a blue object, this individual experiences qualia that most persons experience only when presented with red objects. And so forth - the Invert's color spectrum is the inverse of normal; there are systematic inter-subjective differences in qualia. (shrink)

This short paper states a new objection against “spectrum arguments” for nontransitive betterness. It is shown that defenders of such arguments must reject one of two very plausible principles.

This article responds to Oscar Horta’s article “In Defense of the InternalAspects View: Person-Affecting Reasons, Spectrum Arguments andInconsistent Intuitions”. I begin by noting various points of agreementwith Horta. I agree that the “better than relation” is asymmetric, and pointout that this will be so on an Essentially Comparative View as well as on anInternal Aspects View. I also agree that there are various possible Person-Affecting Principles, other than the one my book focuses on, that peoplemight find plausible, and that (...) in some circumstances, at least, these mighthave deontological, rather than axiological significance. In particular,I grant that Horta’s Actuality-Dependent Person-Affecting Principle, hisTime-Dependent Person-Affecting Principle, and his Identity-DependentPerson-Affecting Principle, might each be relevant to what we ought todo, without necessarily being relevant to which of two outcomes is better.But I reject Horta’s claim that essentially comparative principles don’tapply in Spectrum Arguments. I also argue against Horta’s view that thetwo Standard Views that underlie our intuitions in Spectrum Argumentsare contradictory. I question Horta’s position that there isno point in rejecting the transitivity of the “better than” relation on thebasis of Spectrum Arguments, on the grounds that doing so won’t solvethe predicament that Spectrum Arguments pose. Finally, I conclude mypaper by challenging Horta’s interesting contention that my views aboutnontransitivity support an anti-realist metaethics, and are incompatiblewith the sort of realist approach to metaethics that I favor.

The objective of this paper is to defend the non-reductive thesis of phenomenal consciousness. This paper will give an overview of the arguments for the non-reductive explanation of phenomenal consciousness and justify why the reductionist approach is implausible in the context of explaining phenomenal subjective experience. The debate between reductionist and non-reductionist on the project of demystifying and mystifying phenomenal consciousness is driven by two fundamental assumptions-1) Reductive-Naturalistic Objectivism, 2) Phenomenal Realism. There are several arguments for the irreducibility of phenomenal (...) consciousness; this paper will focus on the inverted spectrum argument, knowledge argument, and the conceivability argument.

According to the Internal Aspects View, the value of different outcomesdepends solely on the internal features possessed by each outcome and theinternal relations between them. This paper defends the Internal AspectsView against Larry Temkin’s defence of the Essentially Comparative View,according to which the value of different outcomes depends on what isthe alternative outcome they are compared with. The paper discusses bothperson-affecting arguments and Spectrum Arguments. The paper doesnot defend a person-affecting view over an impersonal one, but it arguesthat although (...) there are intuitive person-affecting principles that entail anEssentially Comparative View, the intuitions that support these principlescan also be acommodated by other principles that are compatible with theInternal Aspects View. The paper also argues that the rejection of transitivityand the Internal Aspects View does not help us to solve the challengespresented by Spectrum Arguments. Despite this, the arguments presentedby Temkin do succeed in showing that, unfortunately, our intuitions arechaotic and inconsistent. The paper argues that this has metaethicalconsequences that will be unwelcome by a moral realist such as Temkin,since they challenge the idea that our intuitions may track a moral realityexisting independently of our preferences.

Purest points of Hering's six primary colors reside at different levels of lightness such that inversion of each hue pair would be detectable in subjects' choice of foci on the Munsell array. An inverted spectrum would not impose the isomorphism constraint on a contrast of red-green or yellow-blue, whatever we conclude about inference in functionalism.

Medical assistance in dying was legalized by the Supreme Court of Canada in June 2016 and became a legal, viable end of life care option for Canadians with irremediable illness and suffering. Much attention has been paid to the balance between physicians’ willingness to provide MAiD and patients’ legal right to request medically assisted death in certain circumstances. In contrast, very little attention has been paid to the challenge of making MAiD accessible to vulnerable populations. The purpose of this paper (...) was to examine the extant literature and resources that are available on the provision of MAiD in Canada. We found that the provision of EOLC in Canada offers insufficient access to palliative and EOLC options for Canadians and that vulnerable Canadians experience disproportional barriers to accessing these already limited resources. Consequently, we argue that palliative care, hospice care and MAiD must be considered a spectrum of EOLC that is inclusive and accessible to all Canadians. We conclude by imploring Canadian healthcare professionals, policy makers and legislators to consider MAiD as a viable EOLC option for all Canadians. (shrink)

This chapter examines the spectrum inversion hypothesis as an argument against certain kinds of account of what it’s like to be conscious of color. The hypothesis aims to provide a counterexample to accounts of what it’s like to be conscious of color in non-qualitative terms, as well as to accounts of what it’s like to be conscious of color in terms of the representational content of conscious visual states (which, according to some philosophers, is in turn given an (...) account in non-qualitative terms). I explain the hypothesis’s reasoning in sections 1 and 2. I then take up background issues: since the counterexample provided by the hypothesis is typically given as a possibility rather than an actuality, I briefly discuss the kind of possibility involved in section 3, and the methodologies used to evaluate the plausibility of possibilities in section 4. In section 5, I describe some general considerations that are commonly used against the spectrum inversion hypothesis. I take up attempts to support the hypothesis with findings from color science in section 6. I end with comments skeptical of both the motivation for the spectrum inversion hypothesis and the methodology used to support it. (shrink)

Even if spectrum inversion of various sorts is possible, spectrum inversion without a difference in representation is not. So spectrum inversion does not pose a challenge for the intentionalist thesis that, necessarily, within a given sense modality, if two experiences are alike with respect to content, they are also alike with respect to their phenomenal character. On the contrary, reflection on variants of standard cases of spectrum inversion provides a strong argument for intentionalism. Depending on (...) one’s views about the possibility of spectrum inversion, the impossibility of spectrum inversion without a difference in representation can also be used as an argument against a variety of reductive theories of mental representation.

Slaman and Wehner have constructed structures which distinguish the computable Turing degree 0 from the noncomputable degrees, in the sense that the spectrum of each structure consists precisely of the noncomputable degrees. Downey has asked if this can be done for an ordinary type of structure such as a linear order. We show that there exists a linear order whose spectrum includes every noncomputable Δ 0 2 degree, but not 0. Since our argument requires the technique of (...) permitting below a Δ 0 2 set, we include a detailed explanation of the mechanics and intuition behind this type of permitting. (shrink)

Derek Parfit's combined-spectrum argument seems to conflict with epistemicism, a viable theory of vagueness. While Parfit argues for the indeterminacy of personhood, epistemicism denies indeterminacy. But, we argue, the linguistically based determinacy that epistemicism supports lacks the sort of normative or ontological significance that concerns Parfit. Thus, we reformulate his argument to make it consistent with epistemicism. We also dispute Roy Sorensen's suggestion that Parfit's argument relies on an assumption that fuels resistance to epistemicism, namely, that (...) 'the magnitude of a modification must be proportional to its effect.'. (shrink)

Martine Nida-Rümelin (1996) argues that color science indicates behaviorally undetectable spectrum inversion is possible and raises this possibility as an objection to functionalist accounts of visual states of color. I show that her argument does not rest solely on color science, but also on a philosophically controversial assumption, namely, that visual states of color supervene on physiological states. However, this assumption, on the part of philosophers or vision scientists, has the effect of simply ruling out certain versions of (...) functionalism. While Nida-Rümelin is quite right to search for empirical tests for claims about the nature of visual states, philosophical issues remain pivotal in determining the correctness of these claims.

Why do artists, poets, philosophers, writers, and others who are usually classified as intellectuals leave the ivory tower to "dirty their hands" in the political arena? In an effort to illuminate the intellectual's struggle to come to grips with the issues raised by political involvement, David Schalk examines the life and thought of five intellectuels engagés in France during the period between 1920 and 1945. From communist to fascist, these figures—Paul Nizan, Jean-Paul Sartre, Emmanuel Mounier, Julien Benda, and Robert Brasillach—cover (...) the full political spectrum, and Professor Schalk studies their diverse reactions to the social, political, and economic tensions of the interwar period. Broadly defining "engagement" as political involvement that is voluntary, conscious, and freely chosen, usually by intellectuals, the author poses the intellectual's dilemma in the following terms: "When we are engagé," he writes, "we fear that we are debasing our highest values; when we are not, we worry that we have become, in Paul Nizan's trenchant phrase, mere chiens de garde [watchdogs]." He then investigates the origins and the popularization of the concept of engagement in the early 1930s, the arguments used to denounce it and to defend it, its different manifestations, and finally its effects on the socio-political actuality of the world.

Argumentations are at the heart of the deductive and the hypothetico-deductive methods, which are involved in attempts to reduce currently open problems to problems already solved. These two methods span the entire spectrum of problem-oriented reasoning from the simplest and most practical to the most complex and most theoretical, thereby uniting all objective thought whether ancient or contemporary, whether humanistic or scientific, whether normative or descriptive, whether concrete or abstract. Analysis, synthesis, evaluation, and function of argumentations are described. Perennial (...) philosophic problems, epistemic and ontic, related to argumentations are put in perspective. So much of what has been regarded as logic is seen to be involved in the study of argumentations that logic may be usefully defined as the systematic study of argumentations, which is virtually identical to the quest of objective understanding of objectivity.

Christopher Peacocke has recently made an important and insightful effort to fashion a non-verificationist method for distinguishing sense from nonsense. The argument is subtle and complex, and varies somewhat with each of his three target ‘spurious hypotheses’: that if a perfect fission of one person into two were to occur, one and only one of the resulting persons would be identical with the original; that another person’s visual experience can be qualitatively different from your own when you are both (...) seeing the same object, even though your relevant brain states are physically identical and so are your environmental conditions; and that the entire material universe is moving undetectably at a particular uniform velocity with respect to absolute space. My own assessment of his efforts is that they are most successful against the third of these hypotheses, and that this is a function of the fact that of the three, it alone clearly employs a problematic concept- that of absolute location. However, my purpose here is not to engage in a comprehensive evaluation of Peacocke’s project; it is rather to defend the extreme inverted spectrum hypothesis against his attack. I shall argue not only that his argument against EISH fails, but that he is himself independently committed to its intelligibility. Beyond that, I shall point out some striking and, to my mind, welcome consequences of his plausible claims concerning the relations between his own proposal and certain other views concerning content theory; the consequences in question depend both on his positive proposal and on my reasons for rejecting his argument against the extreme inversion hypothesis.

The Theory Theory (TT) versus Simulation Theory (ST) debate is primarily concerned with how we understand others’ mental states. Theory theorists claim we do this using rules that are akin to theoretical laws, whereas simulation theorists claim we use our own minds to imagine ourselves in another’s position. Theorists from both camps suggest a consideration of individuals with autism spectrum disorders (ASD) can help resolve the TT/ST debate (e.g., Baron-Cohen 1995; Carruthers 1996a; Goldman 2006). We present a three-part (...) class='Hi'>argument that such research has so far been inconclusive and that the prospects for studies of ASD to resolve the debate in the near future remain uncertain. First, we discuss evidence indicating that some individuals with ASD can perform effectively on tests of mental state understanding, which questions what ASD can tell us regarding theorising or simulation. Second, we claim that there is compelling evidence that domain-general mechanisms are implicated in mental state reasoning, which undermines how ASD might inform the TT/ST debate given that both theories appeal to domain-specific mindreading mechanisms. Third, we suggest that neuroscientific evidence for an assumed role of the mirror neuron system in autism also fails to arbitrate between TT and ST. We suggest that while the study of ASD may eventually provide a resolution to the TT/ST debate, it is also vital for researchers to examine the issues through other avenues, for example, by examining people’s everyday counterfactual reasoning with mental state scenarios.

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.

In ‘Wittgenstein and Qualia’ Ned Block argues for the existence of inverted spectra and those ineffable things, qualia. The essence of his discussion is a would-be proof, presented through a series of pictures, of the possible existence of an inverted spectrum.

I hold that a key premise of this proof is (...) incoherent. Furthermore, Block’s dangerous scenario does not follow from Wittgenstein’s innocent one, as Block believes it does, but rather is in conflict with it. (shrink)

Polarization is a generalized feature of intellectual life. Few authors however have studied polarities as they actually occur in every day life and discourse. This paper proposes two hypotheses to account for the pervasiveness of polarities. The first relates to uncertainty. Almost everything that touches our lives is filled with irreducible uncertainty. As a rhetoric, polarization uses arguments from (future) consequences in order to manage the future. The second hypothesis relates to phenomenology: body and behavior incorporate tensions or dualistic properties (...) which are easily reproduced in language and thinking. Polarized thinking helps people to imagine extremes so that they may better anticipate the spectrum of possibilities available for action. The article concludes with remarks on the dangers of (over)generalizing and universalizing particulars (or extremes) in polarity based argumentation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:On Doing Theology and Buddhology:A Spectrum of Christian ProposalsAmos YongThis essay addresses the following questions: "Can/should Buddhists and Christians do theology/Buddhology together? If no, why not? If yes, why and how?" As a Pentecostal Christian systematician and comparativist, I review a number of volumes recently published in the field in light of these queries1 and situate them across a typological spectrum.2 I will conclude by providing my (...) own constructive theological response.3Evangelical VoicesKeith Yandell, the Julius R. Weinberg Professor of Philosophy at the University of Wisconsin, Madison, and Harold Netland, former missionary to Japan and longtime faculty member in philosophy of religion and intercultural studies at Trinity Evangelical Divinity School in Deerfield, Illinois—one of the most important evangelical seminaries in North America—have collaborated on a volume recently jointly released by two of the most important evangelical publishing houses, InterVarsity Press and Paternoster Press.4 These are senior evangelical scholars; between them, they have written or edited numerous books in the areas of philosophy of religion, epistemology, theology of pluralism, and theology of interreligious encounter, among other topics, along the way touching on many aspects of the subject matter in their coauthored book, Buddhism.5 How would they respond to the set of questions above? More particularly, how might we anticipate their response in light of their book?In contrast to previous evangelical engagements with Buddhist traditions, Yandell and Netland provide an exemplary model for future evangelical discussions of Buddhism in the following respects. First, they take the time to understand Buddhist traditions on their own terms, devoting the first half of their book to a historical exposition of Buddhism's emergence, growth, and development across Asia and the West. Second, both have familiarized themselves with the diversity of Buddhist debates and internal disputes, and thus recognize that Buddhists rarely speak with [End Page 103] one voice, especially on complex issues; this is important since it enables them, by and large, to avoid caricatures of Buddhist positions and of erecting straw-man arguments against Buddhist doctrines and ideas. Last but not least, Yandell and Netland do engage in negative apologetics against central Buddhist doctrines,6 as might be expected of evangelical scholars, but they undertake their critical analysis respectfully and with dialogical rhetoric quite different from the kinds of polemic deployed by prior generations of evangelicals.7Yet even given these advances, in the end, Yandell and Netland emphasize the incommensurability of Buddhism and Christianity. The final chapter of their book distinguishes Christian views of God versus Buddhist conceptions of ultimate reality, Jesus vis-à-vis the Buddha, and the human fall into sin needing gracious forgiveness over and against human ignorance needing enlightenment. Their concluding words assert: "These are not simply variations on a common theme, or different ways of expressing the same spiritual insight. The choice here is between two radically different perspectives on reality, on the nature of the human predicament, and the way to overcome it."8To be sure, Yandell and Netland have provided reasoned arguments for such a contrastive perspective, emphasizing especially what they feel to be the incoherence or unintelligibility of the Buddhist teachings that they examine. But if their evangelical readers agree with their conclusions, it will be only because they are not in the position to appreciate—the expositions of this volume notwithstanding—how Buddhists have wrestled with these issues over the millennia but yet come to peace with some of the answers that continue to mystify Yandell and Netland. More specifically, this book will probably appeal to evangelicals because they also presume the sort of either/ or logic at work in its central arguments. Put alternatively, the Buddhist worldview will remain baffling to most evangelicals because they either lack access to or refuse to avail themselves of the practices that give these ideas meaning. Such is the cost of staying primarily at the level of philosophical discourse and analysis.9This probably means that Yandell and Netland would answer "no" to the leading questions of this essay. Christians and Buddhists occupy, in their perspective, incommensurable religious and intellectual grounds. Sustained interreligious encounter can result only in the awareness of the differences...

David Chalmers' dancing qualia argument is intended to show that phenomenal experiences, or qualia, are organizational invariants. The dancing qualia argument is a reductio ad absurdum, attempting to demonstrate that holding an alternative position, such as the famous inverted spectrum argument, leads one to an implausible position about the relation between consciousness and cognition. In this paper, we argue that Chalmers' dancing qualia argument fails to establish the plausibility of qualia being organizational invariants. Even stronger, (...) we will argue that the gap in the argument cannot be closed. (shrink)

Some find it plausible that a sufficiently long duration of torture is worse than any duration of mild headaches. Similarly, it has been claimed that a million humans living great lives is better than any number of worm-like creatures feeling a few seconds of pleasure each. Some have related bad things to good things along the same lines. For example, one may hold that a future in which a sufficient number of beings experience a lifetime of torture is bad, regardless (...) of what else that future contains, while minor bad things, such as slight unpleasantness, can always be counterbalanced by enough good things. Among the most common objections to such ideas are sequence arguments. But sequence arguments are usually formulated in classical logic. One might therefore wonder if they work if we instead adopt many-valued logic. I show that, in a common many-valued logical framework, the answer depends on which versions of transitivity are used as premises. We get valid sequence arguments if we grant any of several strong forms of transitivity of 'is at least as bad as' and a notion of completeness. Other, weaker forms of transitivity lead to invalid sequence arguments. The plausibility of the premises is largely set aside here, but I tentatively note that almost all of the forms of transitivity that lead to valid sequence arguments seem intuitively problematic. Still, a few moderately strong forms of transitivity that might be acceptable lead to valid sequence arguments, although weaker statements of the initial value claims avoid these arguments at least to some extent.

One form of argument from analogy is identified and Stephen Barker's remarks about a second kind of argument from analogy, non-inductive (and non-deductive) argument from analogy, are used as a springboard to identify a second form.

It is argued that there is a spectrum of different forms of argument from analogy, with the two forms identified being end points on the spectrum. (...) Except in terms of form, however, there is no reason to speak of two different kinds of argument from analogy. (shrink)

In this paper, we look at Richard Dawkins’ “Spectrum of Theistic Probabilities” from his book “The God Delusion”. The spectrum is edited to account for a mathematical error by Richard Dawkins. Correcting this oversight leads to 2 new theological positions being discovered. One of these positions is defended in detail. In its defense, we argue against a potential flaw of the position and also list a merit for the position among other arguments for the position. The merit involves (...) a rebuttal for Pascal’s wager found in no other piece of literature. (shrink)

Both arguments are based on the breakdown of normal criteria of identity in certain science-fictional circumstances. In one case, normal criteria would support the identity of person A with each of two other persons, B and C; and it is argued that, in the imagined circumstances, A=B and A=C have no truth value. In the other, a series or spectrum of cases is tailored to a sorites argument. At one end of the spectrum, persons A and B (...) are such that A=B is clearly true; at the other end, A and B are such that the identity is clearly false. In between, normal criteria of identity leave the truth or falsehood of A=B undecided, and it is argued that in these circumstances A=B has no truth value.These arguments are to be understood counterfactually. My claim is that, so understood, neither establishes its conclusion. The first involves a pair of counterfactual situations that are equally possible or tied. If A=B and A=C have no truth value, a counterfactual conditional with one of them as consequent and an antecedent that is true in circumstances in which either is true should have no truth value. Intuitively, however, any such counterfactual is false. The second argument can be seen to invite an analogous response. If this is right, however, there is an important disanalogy between this and the classical paradox of the heap. If the disanalogy is only apparent, the argument shows at most that the existence of persons can be indeterminate. (shrink)

An epistemological orthodox view holds that knowing that p is an absolute ‘yes-or-no’ affair rather than something that comes in degrees. The rising epistemic gradualist theory challenges this orthodoxy by arguing that knowledge-that is a gradable concept. The predominant form of argument for gradualism in the current literature is the argument from component, according to which knowledge is gradable because its various components (e.g., justification, belief, truth) are gradable. I will show that the argument from components involves (...) a non-sequitur: the alleged gradability of knowledge’s components cannot ensure the gradability of knowledge per se. The crux of this logical lacuna lies in that the argument neglects the external gradability of knowledge, viz, there is no clear-cut threshold between knowledge and lack thereof. The lacuna can be mended by seeing knowledge-that as a spectrum concept such that a more complete gradualist picture can be achieved. (shrink)

This essay explores the dialectics of theory and practice in terms of argumentation theory. Adapting Jonsen and Toulmin's (1988) notion of a Theory-Practice spectrum, it conceives Theory and Practice as extreme ends of a continuum and discourses as falling at various points along the continuum. Every theoritical discourse has essential practical aspects, and every practical discourse has essential theoretical aspects. Practices are theorized to varying degrees but every practice is thorized to some degree. Reflective discourse, which is discourse about (...) practice, moves to and fro along the Theory-Practice continuum. Reflective discourse involves argumentation. Practical argumentation connects theory to practice; it appeals to general warrants, which may be simple or may tap into elaborate conceptual structures, in order to establish grounds for practical judgments. A practical discipline is a relatively coherent intellectual-professional enterprise that cultivates a field of social practice by engaging within itself and with practitioners in a reflective discourse. The argumentation of a practical discipline, like ordinary practical reflection, moves to and fro along the Theory-Practice continuum but in more methodical steps informed by systematic methodological reflection on the reflective process itself.

Scientific realists argue that a good track record of multi-agent, and multiple method, validation of empirical claims is itself evidence that those claims, at least partially and approximately, reflect ways nature actually is independent of the ways we conceptualize it. Constructivists contend that successes in validating empirical claims only suffice to establish that our ways of modelling the world, our “constructions,” are useful and adequate for beings like us. This essay presents a thought experiment in which beings like us intersubjectively (...) validate claims about properties of particular things in nature under conditions in which those beings have profoundly different personal phenomenological experiences of those properties. I submit that the thought experiment scenario parallels our actual situation, and argue that this shows that successes in intersubjectively validating empirical claims are indeed enough to claim victory for the realist. More specifically, I champion a variation of realism that marries Ronald Giere’s brand of ‘perspectival realism’ with Philip Kitcher’s ‘real realism,’ and posits that causal relations between ourselves and properties instantiated in nature ground our references to the relevant properties even though our conceptions of them are perspective relative.

In recent decades, the focus in autism research progressively expanded. It presently offers extensive material on sensorimotor disturbances as well as on perceptive-cognitive preferences of people with autism. The present article proposes not only a critical interpretation of the common theoretical framework in autism research but also focuses on certain experiences common to some people with autism and which can be appropriately understood by phenomenology. What I will call “hypnotic experiences” in autism are moments in which some individuals withdraw into (...) intense sensorial and perceptive experiences. Following their examples, I use the term “hypnosis” primarily to describe a trance state in which the individuals become highly alert to and awake for an experience of a totally new kind. Through a close analysis of autobiographical writings from people with autism I defend the idea that the particularity of hypnotic experiences in autism consists in a certain qualitative shift within experience itself: what changes, in the hypnotic moments, is the way a person with autism relates to his/her own bodily experiences. If this qualitative shift is indeed difficult to account for within a reifying and intellectualist research perspective, phenomenology offers a large conceptual framework for understanding it. Phenomenology, and precisely, phenomenological psychopathology, will thus emerge as a major device in accounting for such “hypnotic experiences”. The argument mainly draws on the twofold structure of experience which is traditionally used in phenomenological research: it claims that in hypnotic experience people with autism are inclined to focus on non-reified “sensings”, “perceivings” and “movings”, and thus leave aside the object itself and any intentional reification of it. Finally, I will claim that this restriction to mere non-reified sensings might lead to a completely new conception of self and world. In the hypnotic experiences of autism, neither the subject nor the object come to a full-blown and independent existence. A thorough phenomenological analysis of hypnotic experience in autism therefore also has to face the question of a corresponding ontology of these experiences. (shrink)

Augmenting and supplementing the arguments of Crespi & Badcock (C&B), I show that digit ratio (2D:4D), a putative marker of prenatal androgen action, indeed appears differentially altered in autism-spectrum disorders (lower/masculinized) versus schizophrenic-spectrum disorders (higher/feminized). Consistent with C&B's framework, some evidence (substantial heritability, assortative mating, sex-specific familial transmission) points to possible sex chromosome and imprinted genes effects on 2D:4D expression.

Timothy Smiley has made ground-breaking contributions to modal logic, free logic, multiple-conclusion logic, and plural logic. He has illuminated Aristotle’s syllogistic, the ideas of logical form and consequence, and the distinction between assertion and rejection, and has worked to debunk the theory of descriptions. This volume brings together new articles by an international roster of leading logicians and philosophers in order to honour Smiley’s work. Their essays will be of significant interest to those working across the logical spectrum—in philosophy (...) of language, philosophical and mathematical logic, and philosophy of mathematics.

Is research fraud deliberate? Is research fraud / serious misconduct in medicine deliberate or inadvertent? This is clearly an important question and one that is subject to a lot of controversy. Many researchers seem to believe that fraud is always either the result of some kind of psychiatric condition, or just at one extreme of a spectrum of inadvertent error. How do we find out? We could ask fraudulent researchers, but would probably not get honest answers. The ingenious study (...) by Steen published in this issue points towards fraud often being deliberate. Steen's sample are all papers retracted from the PubMed database between 2000 and 2010. He divides these up in papers retracted due to error and papers retracted due to fraud and hypothesises that if fraud is deliberate then we can expect that “… fraudulent authors target journals with a high impact factor, have other fraudulent publications, diffuse responsibility across many co-authors, delay retracting fraudulent papers ….

"The book's major parts, one on polarity and the other on analogy, introduce the reader to the patterns of thinking that are fundamental not only to Greek philosophy but also to classical civilization as a whole. As a leading classicist in his own right, Lloyd is an impeccable guide. His sophistication in adducing anthropological parallels to Greek models of polarity and analogy broadens his perspective, making him a forerunner in the study of what we are now used to calling semiotics. (...) A striking example of Lloyd's approach is his re-examination of the dichotomy of Olympian and chthonian gods in ancient Greek world view, which surpasses the reductionist and pseudo-historical models of sky-gods and earth-goddesses that are still commonly invoked to account for polarities in Greek pantheon. "In the second part, dealing with analogy, three crucial metaphorical models for the universe turn out to be basis for a dazzlingly wide variety of scientific and philosophical perspectives. Each model is tested in the whole spectrum of Greek artistic, philosophical and scientific thought. This work is a treasure-house of insights for experts and non experts alike." --Gregory Nagy, Harvard University. (shrink)

Recent advancements in developmental biology enable the creation of embryo-like structures from human stem cells, which we refer to as human embryo-like structures (hELS). These structures provide promising tools to complement—and perhaps ultimately replace—the use of human embryos in clinical and fundamental research. But what if these hELS—when further improved—also have a claim to moral status? What would that imply for their research use? In this paper, we explore these questions in relation to the traditional answer as to why human (...) embryos should be given greater protection than other (non-)human cells: the so-called Argument from Potential (AfP). According to the AfP, human embryos deserve special moral status because they have the unique potential to develop into persons. While some take the development of hELS to challenge the very foundations of the AfP, the ongoing debate suggests that its dismissal would be premature. Since the AfP is a spectrum of views with different moral implications, it does not need to imply that research with human embryos or hELS that (may) have ‘active’ potential should be completely off-limits. However, the problem with determining active potential in hELS is that this depends on development passing through ‘potentiality switches’ about the precise coordinates of which we are still in the dark. As long as this epistemic uncertainty persists, extending embryo research regulations to research with specific types of hELS would amount to a form of regulative precaution that as such would require further justification.

This article provides a map of the UBI debate, structured into the main themes that guide and group the arguments on both sides. It finds that UBI’s supporters and opponents both draw on core principles of justice and freedom, focusing on need and poverty, discrimination and inequality, growth, social opportunity, individuality, and self-development. From an economic perspective, they both appeal to business concerns about efficiency, risk, flexibility, and consumption, as well as labour interests on work fulfilment, working conditions, remuneration, and (...) bargaining. Likewise, they focus on political questions around welfare state reforms, redistribution, taxation and funding sources, democratic citizenship, and the prospects for cross-party policy coalitions. By providing an overview of the thematic pillars of the UBI debate, this article helps researchers and activists locate and orient themselves within the wider spectrum of opinion on UBI. (shrink)

Newly accessible source material calls for a revision of our picture of the more technical transmission of sceptical epistemologies in the intellectual landscape of early Islam. Abū al‐Qāsim al‐Balkhīʼs (ninth/tenth century) Book of Doctrines shows that naẓar as the basic argumentative method of kalām is defined by the encounter with a broad spectrum of sceptical strategies. By the beginning of the tenth century, Greek traditions were amalgamated in a complex way with other intellectual traditions, most notably dualist ontologies. This (...) situation has shaped the evolution of kalām methodology decisively. Based on extensive paraphrases in Ibn al‐Malāḥimī (twelfth century) going back to Nawbakhtī (tenth century), it can be seen that arguments of the Greek sceptical tradition were accessible in Arabic in the early tenth century. The scarcity of coherent information on sceptical approaches before that time rather has to do with the problem that in general few sources of this earlier formative period of Islamic theology are preserved. Early Muʿtazilī treatises from this period are superseded by Ashʿarī texts in the later transmission. Sceptical approaches, being systematically involved in the very formation of early Muʿtazilī theology, are particularly invisible due to this process. (shrink)

The existence of big bang relic neutrinos—exact analogues of the big bang relic photons comprising the cosmic microwave background radiation—is a basic prediction of standard cosmology. The standard big bang theory predicts the existence of 1087 neutrinos per flavour in the visible universe. This is an enormous abundance unrivalled by any other known form of matter, falling second only to the cosmic microwave background (CMB) photon. Yet, unlike the CMB photon which boasts its first (serendipitous) detection in the 1960s and (...) which has since been observed and its properties measured to a high degree of accuracy in a series of airborne/satellite and ground based experiments, the relic neutrino continues to be elusive in the laboratory. The chief reason for this is of course the feebleness of the weak interaction. At present, the observational evidence for their existence rests entirely on cosmological measurements, such as the light elemental abundances, anisotropies in the cosmic microwave background, and the large-scale matter power spectrum. In this paper we argue that Direct Detection of relic neutrino background is indeed impossible by any means, because of two chief reasons: (a) there was no such thing of cosmic singularity, hence the hot big bang/primeval atom model was based on false premises (quantum birth assumption); (b) the neutrino existence itself is not unquestionable, in particular if we consider a realism view of vector potential, A, in classical electrodynamics.
