This paper investigates the significance of T-duality in string theory: the indistinguisha- bility with respect to all observables, of models attributing radically different radii to space – larger than the observable universe, or far smaller than the Planck length, say. Two interpretational branch points are identified and discussed. First, whether duals are physically equivalent or not: by considering a duality of the familiar simple harmonic oscillator, I argue that they are. Unlike the oscillator, there are no measurements ‘outside’ string theory (...) that could distinguish the duals. Second, whether duals agree or disagree on the radius of ‘target space’, the space in which strings evolve according to string theory. I argue for the latter position, because the alternative leaves it unknown what the radius is. Since duals are physically equivalent yet disagree on the radius of target space, it follows that the radius is indeterminate between them. Using an analysis of Brandenberger and Vafa (1989), I explain why – even so – space is observed to have a determinate, large radius. The conclusion is that observed, ‘phenomenal’ space is not target space, since a space cannot have both a determinate and indeterminate radius: instead phenomenal space must be a higher-level phenomenon, not fundamental.

I argue that an evaluational conception of love collides with the way we value love. That way allows that love has causes, but not reasons, and it recognizes and celebrates a love that refuses to justify itself. Love has unjustified selectivity, due to its arbitrary causes. That imposes a non-tradability norm. A love for reasons, rational love or evaluational love would be propositional, and it therefore allows that the people we love are tradable commodities. A moralized conception of love is (...) no less committed to treating those we love as tradable commodities; it is just that they are tradable moral commodities. An evaluative criterion of adequacy, I suggest, encourages the opposite view ? a non-rational and non-evaluational concept of love. Such a love can set up partial obligations, which may even demand that one sacrifice one's life. Only a love that has causes but not reasons can have the kind of value that we think love has, and thus it would only be rational to pursue and foster such a love. (shrink)

I probe the judgments of the agreeable that we make about food and drink. I first separate different concerns that we might have with food and drink. After that, I address expressive language by first sketching an evolutionary language-game-theoretic approach for referential language. I then try to extend it to expressive language, showing how expressive signaling might be likely to evolve. Given an account of expressive prediction, and its point, I turn to the Frege-Geach problem for the agreeable. I show (...) how a proper understanding of what expression is, in the evolutionary language-game-theoretic framework, allows us to side-step a central aspect the problem. (shrink)

Muller and Saunders ([2008]) purport to demonstrate that, surprisingly, bosons and fermions are discernible; this article disputes their arguments, then derives a similar conclusion in a more satisfactory fashion. After briefly explicating their proof and indicating how it escapes earlier indiscernibility results, we note that the observables which Muller and Saunders argue discern particles are (i) non-symmetric in the case of bosons and (ii) trivial multiples of the identity in the case of fermions. Both problems undermine the claim that they (...) have shown particles to be physically discernible. We then prove two results concerning observables that are truly physical: one showing when particles are discernible and one showing when they are not (categorically) discernible. Along the way we clarify some frequently misunderstood issues concerning the interpretation of quantum observables. 1 Background2 Criticisms2.1 Bosons2.2 Fermions3 Reformulating the Insight3.1 What weakly discerns?3.2 General results4 Conclusion.

The Doomsday argument purports to show that the risk of the human species going extinct soon has been systematically underestimated. This argument has something in common with controversial forms of reasoning in other areas, including: game theoretic problems with imperfect recall, the methodology of cosmology, the epistemology of indexical belief, and the debate over so-called fine-tuning arguments for the design hypothesis. The common denominator is a certain premiss: the Self-Sampling Assumption. We present two strands of argument in favor of this (...) assumption. Through a series of thought experiments we then investigate some bizarre prima facie consequences – backward causation, psychic powers, and an apparent conflict with the Principal Principle.

I reply to Andrea Baldini's critical discussion of my "Street Art: The Transfiguration of the Commonplaces" (2010) by taking up the question: what is "the street" in street art? I argue that the relevant notion of the street is a space whose function it is to facilitate self-expression. I show how this clarifies and extends the theory developed in Riggle (2010). I then argue, contra Baldini, that street art is not always subversive, and when it is, it is not always (...) in virtue of its challenging the co-opting of public space by commercial art. (shrink)

How sexuality should be regulated in a liberal political community is an important, controversial theoretical and empirical question—as shown by the recent criminalization of possession of some adult pornography in the United Kingdom. Supporters of criminalization argue that Mill, often considered a staunch opponent of censorship, would support prohibition due to his feminist commitments. I argue that this account underestimates the strengths of the Millian account of private conduct and free expression, and the consistency of Millian anticensorship with feminist values. (...) A Millian contextual defense of liberty, however, suggests several other policy approaches to addressing the harms of pornography. (shrink)

If Bayesian Fundamentalism existed, Jones & Love's (J&L's) arguments would provide a necessary corrective. But it does not. Bayesian cognitive science is deeply concerned with characterizing algorithms and representations, and, ultimately, implementations in neural circuits; it pays close attention to environmental structure and the constraints of behavioral data, when available; and it rigorously compares multiple models, both within and across papers. J&L's recommendation of Bayesian Enlightenment corresponds to past, present, and, we hope, future practice in Bayesian cognitive science.

I argue that people do not and cannot have religious experiences that are perceptual experiences with theological content and that provide some justification for the belief in God. I discuss William Alston's resourceful defence of this idea. My strategy is to say that religious perception would either have to be by means of one of the ordinary five senses or else by means of some special sixth religious sense. In either case insoluble epistemological problems arise. The problem is with perceiving (...) God as God, which we need to do if reasons to believe in God are to be generated. To do so, we would have to perceive the instantiation of His essential properties – being all-knowing, all-powerful, and all-good. But perceiving the instantiation of these properties of God, even by some special sixth religious sense, is impossible. Hence, God cannot be perceived either by the ordinary five senses or by a sixth religious sense. Religious perceptual experiences are a myth. (Published Online February 17 2004). (shrink)

The purpose of this investigation is to develop a ranking of academic business ethics journals. For this, a revealed preference approach, also known as a citation impact method, was employed. The citation data were generated by using Google Scholar; h-index, g-index and hc-index were utilised to obtain a ranking. It was observed that the scores of these three indices correlated almost perfectly. This study also demonstrates that business ethics is a well-established discipline that should have its own set of recognised (...) academic outlets. (shrink)

Despite its central focus on human freedom and individual and social emancipation, critical realism has remained surprisingly quiet on the subject of authenticity. Drawing on a review of critical realist metatheory, and a study of authentic performance in the illuminating cultural context of Early Music, this paper seeks to address this gap by exploring the significance of authenticity in today's morphogenetic society. Real authenticity is introduced as the universal human capacity to reflexively manage the inherent contradictions that arise between and (...) across our intra- and interpersonal relationships at different levels of reality. It is this dialectical, phronetic capacity that determines whether acting in line with our ultimate concerns is both good for us as individuals and the organization of better futures for all. Managing real authenticity, therefore, must be considered at the core of any possible transition theory for human flourishing. (shrink)

According to the Interpersonal View of Testimony, testimonial justification is non-evidential in nature. I begin by arguing that the IVT has the following problem: If the IVT is true, then young children and people with autism cannot participate in testimonial exchanges; but young children and people with autism can participate in testimonial exchanges; thus, the IVT should be rejected on the grounds that it has over-cognized what it takes to give and receive testimony. Afterwards, I consider what I take to (...) be the two best motivations for the IVT and argue that they both fail. The overarching lesson, then, is that the IVT is unmotivated and false; we should think of testimonial justification as being evidential in nature. (shrink)

In his paper "Supervenience Revisisted", Simon Blackburn redeployed his novel modal argument against moral realism as an argument against Donald Davidson's position of 'anomalous monism' in the philosophy of mind (Blackburn 1985).' I shall assess this redeployment. In the first part of this paper, I shall lay out Blackburn's argument. In the second and longer part I shall examine Davidson's denial of psychophysical laws in the light of this argument.

I defend extreme formalism about the aesthetics of inorganic nature. I outline the general issue over aesthetic formalism as it manifests itself in the visual arts. The main issue is over whether we need to know about the history of artworks in order to appreciate them aesthetically. I then turn to nature and concede that with organic nature we need to know a thing's biological kinds if we are fully to appreciate it. However, with in organic nature I deny that (...) we need to know the deeper nature of the things we experience. What is important, I argue, are the appearances of those things not their real natures. I consider the beauty of clouds, which depends on an illusion of solidity, and I argue that scientific knowledge does not reveal beauty that is not available to the ignoramous. There is only the beauty of appearances, and it does not matter whether those appearances are accurate or illusory. (shrink)

The aesthetic realist interprets many descriptions of music as metaphorical descriptions of aesthetic properties of music. I argue that aesthetic realism requires that nonaesthetic words are used to express both aesthetic and nonaesthetic concepts. But having distinguished the concepts, some plausible account must be given of their relation. A causal account of the relation between the possession of aesthetic and nonaesthetic concepts provides this, since the concepts are distinct but connected. I explore and defend this account. I consider the conditions (...) of aesthetic concept possession and also the appropriation of nonaesthetic words in aesthetic descriptions. (shrink)

In this paper it is argued that we can embrace thick properties and thick concepts in moral philosophy as well as aesthetics-on three conditions: (1) that thick concepts are not supposed to function epistemically; (2) that we drop the poor examples—kindness, cruelty, courage, rudeness and the like; and (3) that we explore metaphorical descriptions in moral philosophy, which are descriptions of ways, often inexpressible ways, in which things have moral values.

For any area of our thought — moral, modal, scientihc, or theological we can ask what explains the way we think. After all, we might never have thought in such terms, or that sort of thought might have been different from the way it is. So there must be some explanation of why it is as it is. Such an explanation would be part of a naturalistic account of the mind.

In metaphor we appropriate the literal meanings of words, and use them in ways that do not correspond to their functions. I develop this way of understanding metaphor and situate it within a general functional account of literal word meaning. I show how metaphor can be understood within this framework. I address disagreement with metaphors and the role of logically embedded metaphors, and I show how an appropriation understanding of metaphor yields an explanation of these phenomena.Many artifacts have functions that (...) derive in part from the intentions that result in their creation. For example, a coffeemaker has the function of making coffee, which it has partly because someone intended it to make coffee, and this .. (shrink)

This paper investigates the historiographical utility of psychoanalysis, focussing in particular on retrospective explanations of demonic possession and exorcism. It is argued that while 'full-blown' psychoanalytic explanations-those that impose Oedipus complexes, anal eroticism or other sophisticated theoretical structures on the historical actors-may be vulnerable to the charge of anachronism, a weaker form of retrospective psychoanalysis can be defended as a legitimate historical lens. The paper concludes, however, by urging historians to look at psychoanalysis as well as trying to look through (...) it. Full-blown psychoanalysis is a bad historical lens but it may, in some cases, be an excellent explanatory template: a thorough understanding of how psychoanalytic therapy functions in the modern world is, for example, a good theoretical preparation for historians seeking to understand the sixteenth-century's demonological universe.

What can a moral realist say about why we should take morality seriously and about the relation between morality and rationality? I take off from Christine Korsgaard's criticism of moral realism on this score. The aim is to achieve an understanding of the relation between moral and rational properties and of the role of practical deliberation on a realist view. I argue that the justification for being concerned with rational and moral normative properties may not be an aspect of our (...) minds to which we have access. I argue against a view that gives automatic pride of place to the rational properties of our mind by drawing attention to valuable non-rational modes of thought such as creative, imaginative and instinctive thought. Thus the value of taking account of rationality is contingent on its benefits. But this is not why we should be taking account of morality. (shrink)

BackgroundThe principle of equivalence in prison health has been established for nearly four decades. It seeks to ensure that prisoners have access to the same level of healthcare as members of society at large, which is entrenched within the international legal framework and England’s national health policies.AimsThis study examined how key policymakers interpret and implement the principle of equivalence in English prisons. It also identified opportunities and threats associated with the application of the principle.MethodsIn total, 30 policymakers took part in (...) this research. These participants engaged in policymaking activities and occupied positions of authority in the prison field.ResultsDespite the policymakers’ consensus on the importance of the equivalence principle, there was a varying degree of understanding regarding what constitutes ‘equivalence’. Participants described how the security culture impedes prisoners’ access to healthcare services. Additionally, the increasing size and complexity of the prison population, coupled with a diminishing level of resources, reduce the level of care being provided in prisons and thus compromise implementation of equivalence in English prisons.ConclusionsInconsistent interpretation of equivalence, the prevailing security drive, increasing numbers and health complexities of prisoners and fiscal austerity threaten the implementation of equivalence in English prisons. This research calls for new guidance on how to interpret and implement equivalence, along with measures to educate prison governors and staff on the prison rehabilitation value, ensure greater investment in prison health and consider alternatives to imprisonment to future-proof the principle of equivalence in the English prison system.

Aesthetic theories of art refuse to go away. In spite of decades of criticism and derision, a minority of thinkers stubbornly persist in maintaining that we need a general theory of art that makes essential appeal to beauty, elegance, daintiness, and other aesthetic properties.1 However, those who approach the theory of art from a sociological point of view tend to be skeptical about any account of art that appeals to aesthetic properties in a fundamental way. This skepticism takes two overlapping (...) forms, only one of which I will pursue here. The form of skepticism I am interested in is concerned to deny that we need to appeal to aesthetic considerations in explaining the production of art. Let us call this production skepticism. This form of skepticism does not coincide with skepticism about the appeal to aesthetic considerations in explaining our experiences and judgments about art. Let us call that consumption skepticism. Examples of consumption skeptics are Pierre Bourdieu and Terry Eagleton, who think that aesthetic value judgments about art really reflect social status rather than being a response to qualities of the works.2 In my view, the reasons, such as they are, that Bourdieu and Eagleton put forward in favor of..

I defend the view that morality depends on God against the Euthyphro dilemma by arguing that the reasons that God has for determining the moral-natural dependencies might be personal reasons that have non-moral content. I deflect the 'arbitrary whim' worry, but I concede that the account cannot extend to the goodness of God and His will. However, human moral-natural dependencies can be explained by God's will. So a slightly restricted version of divine commandment theory is defensible.

Williamson (2000) appeals to considerations about when it is natural to say that a hypothesis is consistent with one’s evidence in order to motivate the claim that all and only knowledge is evidence. It is argued here that the relevant considerations do not support this claim, and in fact conflict with it.

The aim of this paper is to explore the minimal representational requirements for pointing. One year old children are capable of pointing – what does this tell us about their representational capacities? We analyse three options: (1) pointing presupposes non-perceptual representations, (2) pointing does not presuppose any representation at all, (3) pointing presupposes perceptual representations. Rather than fully endorsing any of these three options, the aim of the paper is to explore the advantages and disadvantages of each.
