Almost as rapidly as it was conceived, the claim that we have entered an era characterised as 'postmodern' has become highly disputed, and many of the contesting claims do so by mobilising conceptions of space and place and their relationship to apparatuses of movement. Recent scholarship has explored the fact that we are living in a world characterised by an exponential increase of flow, mobility, virtuality and technology. Hence, the notion of postmodernity has been rivalled by alternative concepts such as (...) supermodernity, hypermodernity, liquid modernity or reflexive modernity in an attempt to better grasp the world of the late 20th and early 21st centuries. Beyond the Postmodern: Reconceptualisations of Space and Place for the Early 21st Century combines theoretical reflections of a more general manner with case studies to contribute to a better understanding of how space and place have been constituted by, and constitutive of, the social, technological and economical developments of the last 30 years.

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

Presentations of the extended mind thesis are often ambiguous between two versions of that thesis. According to the first, the extension of mind consists in the supervenience base of human individuals’ mental states extending beyond the skull and into artifacts in the outside world. According to a second interpretation, human individuals sometimes participate in broader cognitive systems that are themselves the subjects of extended mental states. This ambiguity, I suggest, contributes to several of the most serious criticisms of the extended (...) mind thesis, for these criticisms only apply to the first interpretation of the thesis. In what follows, I argue that several significant objections to the extended mind thesis fail to undermine the latter interpretation of that thesis. Having defended the second interpretation, I argue that the extension of mind does not involve the extension of self. Consequently, the subject of extended mental states is not the same individual whose causal coupling with external artifacts gives rise to extended mentality. (shrink)

Several social metaphysicians have argued that groups are constituted by, but not identical to, their members. While the constitution view is promising, there are significant difficulties with existing versions of that view. Fortunately, lessons may be extracted from more traditional metaphysics and applied to the case of group agents. Drawing on such lessons, I present a novel account of the constitution relation holding between individuals and group agents. According to the resulting structural-constitution view, when individuals constitute a group of a (...) certain kind, they do so in virtue of exhibiting the structure characteristic of groups of that kind.

The somewhat superannuated “problem of other minds” has unexpectedly risen from the dead, and, in its current incarnation, concerns the mental states of those who never lived.

The defensibility of the extended mind thesis (EMT) is often thought to hinge on the possibility of extended selves. I argue that the self cannot extend and consider the ramifications of this finding, especially for EMT. After an overview of EMT and the supposed cruciality of the extended self to the defensibility of the former thesis, I outline several lines of argument in support of the possibility of extended selves. Each line of argument appeals to a different account of diachronic (...) personal identity. I argue that no such argument for extended selves succeeds, as no account of diachronic personal identity is both plausible and supports the view that the self can extend. Next, I consider three objections that, if successful, would undercut the preceding argument that the self cannot extend. I conclude by reflecting on the implications of the conclusion that the self cannot extend, including the prospects for EMT. (shrink)

This paper identifies human enhancement as one of the most significant areas of bioethical interest in the last twenty years. It discusses in more detail one area, namely moral enhancement, which is generating significant contemporary interest. The author argues that so far from being susceptible to new forms of high tech manipulation, either genetic, chemical, surgical or neurological, the only reliable methods of moral enhancement, either now or for the foreseeable future, are either those that have been in human and (...) animal use for millennia, namely socialization, education and parental supervision or those high tech methods that are general in their application. By that is meant those forms of cognitive enhancement that operate across a wide range of cognitive abilities and do not target specifically ‘ethical’ capacities. The paper analyses the work of some of the leading contemporary advocates of moral enhancement and finds that in so far as they identify moral qualities or moral emotions for enhancement they have little prospect of success.

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

I defend the view that linguistic meaning is a relation borne by an expression to a type of speech act, and that this relation holds in virtue of our overlapping communicative dispositions, and not in virtue of linguistic conventions. I argue that this theory gives the right account of the semantics–pragmatics interface and the best-available semantics for non-declarative clauses, and show that it allows for the construction of a rigorous compositional semantic theory with greater explanatory power than both truth-conditional and (...) dynamic semantics.

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

Sam Harris dismantles the most common justification for religious faith--that a moral system cannot be based on science.

Knowing how to be good, or knowing how to go about trying to be good, is of immense theoretical and practical importance. And what goes for trying to be good oneself, goes also for trying to provide others with ways of being good, and for trying to make them good whether they like it or not. This is what is meant by 'moral enhancement'. John Harris explores the many proposed methodologies or technologies for moral enhancement: traditional ones like good (...) parenting and education; newer ones like chemical or biological intervention; modifying the environment to make bad outcomes of all sorts less likely; experimentation with political and social systems. The issue of whether and to what extent moral enhancement is possible is the subject of this book. (shrink)

In Enhancing Evolution, leading bioethicist John Harris dismantles objections to genetic engineering, stem-cell research, designer babies, and cloning and makes an ethical case for biotechnology that is both forthright and rigorous. Human enhancement, Harris argues, is a good thing--good morally, good for individuals, good as social policy, and good for a genetic heritage that needs serious improvement. Enhancing Evolution defends biotechnological interventions that could allow us to live longer, healthier, and even happier lives by, for example, providing us (...) with immunity from cancer and HIV/AIDS. Further, Harris champions the possibility of influencing the very course of evolution to give us increased mental and physical powers--from reasoning, concentration, and memory to strength, stamina, and reaction speed. Indeed, he says, it's not only morally defensible to enhance ourselves; in some cases, it's morally obligatory. In a new preface, Harris offers a glimpse at the new science and technology to come, equipping readers with the knowledge to assess the ethics and policy dimensions of future forms of human enhancement.

Biomedical research is so important that there is a positive moral obligation to pursue it and to participate in itScience is under attack. In Europe, America, and Australasia in particular, scientists are objects of suspicion and are on the defensive.i“Frankenstein science”5–8 is a phrase never far from the lips of those who take exception to some aspect of science or indeed some supposed abuse by scientists. We should not, however, forget the powerful obligation there is to undertake, support, and participate (...) in scientific research, particularly biomedical research, and the powerful moral imperative that underpins these obligations. Now it is more imperative than ever to articulate and explain these obligations and to do so is the subject and the object of this paper.Let me present the question in its starkest form: is there a moral obligation to undertake, support and even to participate in serious scientific research? If there is, does that obligation require not only that beneficial research be undertaken but also that “we”, as individuals and “we” as societies be willing to support and even participate in research where necessary?Thus far the overwhelming answer given to this question has been “no”, and research has almost universally been treated with suspicion and even hostility by the vast majority of all those concerned with the ethics and regulation of research. The so called “precautionary approach”9 sums up this attitude, requiring dangers to be considered more likely and more serious than benefits, and assuming that no sane person would or should participate in research unless they had a pressing personal reason for so doing, or unless they were motivated by a totally impersonal altruism. International agreements and protocols—for example, the Declaration of Helsinki10 and the CIOMS Guidelines11—have been directed principally at …. (shrink)

The eighteenth century was a time of brilliant philosophical innovation in Britain. In Of Liberty and Necessity James A. Harris presents the first comprehensive account of the period's discussion of what remains a central problem of philosophy, the question of the freedom of the will. He offers new interpretations of contributions to the free will debate made by canonical figures such as Locke, Hume, Edwards, and Reid, and also discusses in detail the arguments of some less familiar writers. (...) class='Hi'>Harris puts the eighteenth-century debate about the will and its freedom in the context of the period's concern with applying what Hume calls the "experimental method of reasoning" to the human mind. His book will be of substantial interest to historians of philosophy and anyone concerned with the free will problem. (shrink)

In the Western philosophic tradition, virtue theory has rarely been extended to the political realm. There is a long tradition that advocates the role of virtue in ethical theory, but the implications of this tradition for political theory have largely been neglected. However, in the Chinese tradition, we very early on see the use of virtue-based theories not only in ethics but in political thought as well. Indeed, one of the most sophisticated early Confucian philosophers, Xúnzǐ 荀子 (fl. 298–238 BCE), (...) believes that a virtue-based political theory is a natural extension of his virtue-based ethical theory. At the same time, a prominent anti-Confucian political philosopher, Hán Fēizǐ 韓非子, was diametrically opposed to allowing virtue, or, indeed, any other moral quality, serve as the basis for political theory, arguing instead that a clear set of laws should serve as the fundamental basis. Therefore, this tradition offers us a very clear debate on the problems and promise of a virtue politics. This debate is not only of historical interest, however. To the extent that contemporary philosophers interested in the possibility of extending virtue theory to the political realm take themselves to be prescribing for everyone, as opposed to simply for those within their own cultural background, they must be willing to take into account other traditions that have wrestled with similar issues. In early China we not only see a version of virtue politics, we also see a sophisticated debate about its viability. And, while Xúnzǐ himself may not be capable of answering all of Hán Fēizǐ’s objections, analyzing this debate affords us the opportunity to see how and where a particular conception of virtue politics succeeds and fails, providing contemporary philosophers not only with a set of problems that must be overcome but also with a promising way forward.

Existing analyses of disinformation tend to embrace the view that disinformation is intended or otherwise functions to mislead its audience, that is, to produce false beliefs. I argue that this view is doubly mistaken. First, while paradigmatic disinformation campaigns aim to produce false beliefs in an audience, disinformation may in some cases be intended only to prevent its audience from forming true beliefs. Second, purveyors of disinformation need not intend to have any effect at all on their audience’s beliefs, aiming (...) instead to manipulate an audience’s behavior through alteration of sub-doxastic states. Ultimately, I argue that attention to such non-paradigmatic forms of disinformation is essential to understanding the threat disinformation poses and why this threat is so difficult to counter.

This paper describes the ways in which trolls and bots impede the acquisition of knowledge online. I distinguish between three ways in which trolls and bots can impede knowledge acquisition, namely, by deceiving, by encouraging misplaced skepticism, and by interfering with the acquisition of warrant concerning persons and content encountered online. I argue that these threats are difficult to resist simultaneously. I argue, further, that the threat that trolls and bots pose to knowledge acquisition goes beyond the mere threat of (...) online misinformation, or the more familiar threat posed by liars offline. Trolls and bots are, in effect, fake persons. Consequently, trolls and bots can systemically interfere with knowledge acquisition by manipulating the signals whereby individuals acquire knowledge from one another online. I conclude with a brief discussion of some possible remedies for the problem of fake persons. (shrink)

Frances Kamm sets out to draw and make plausible distinctions that would show how and why it is, in some circumstances, permissible to kill some to save many more, but is not so in others. To do so she draws on a famous, and famously artificial, example of Judith Thomson, which illustrates the fact that people intutitively reject some instances of such killings but not others. The irrationality, implausibility and in many cases the self-defeating nature of such distinctions I had (...) attempted to expose in my 'The Survival Lottery' over 25 years ago. I still think these distinctions irrational and implausible and I will try, in this response, to show why this remains the case and why doctrines of additional effects, to however many powers they are taken, remain unhelpful in ethics.

Particularists maintain that conspiracy theories are to be assessed individually, while generalists hold that conspiracy theories may be assessed as a class. This paper seeks to clarify the nature and importance of the debate between particularism and generalism, while offering an argument for a version of generalism. I begin by considering three approaches to the definition of conspiracy theory, and offer reason to prefer an approach that defines conspiracy theories in opposition to the claims of epistemic authorities. I argue that (...) particularists rely on an untenably broad definition of conspiracy theory. Then, I argue that particularism and its counterpart are best understood as constellations of theses, rather than a pair of incompatible theses. While some particularist theses are highly plausible, I argue that one important particularist thesis is false. The argument for this conclusion draws on the history of false conspiracy theories. I then defend this conclusion against a pair of potential objections. (shrink)

Transactive memory theory describes the processes by which benefits for memory can occur when remembering is shared in dyads or groups. In contrast, cognitive psychology experiments demonstrate that social influences on memory disrupt and inhibit individual recall. However, most research in cognitive psychology has focused on groups of strangers recalling relatively meaningless stimuli. In the current study, we examined social influences on memory in groups with a shared history, who were recalling a range of stimuli, from word lists to personal, (...) shared memories. We focused in detail on the products and processes of remembering during in-depth interviews with 12 older married couples. These interviews consisted of three recall tasks: (1) word list recall; (2) personal list recall, where stimuli were relevant to the couples’ shared past; and (3) an open-ended autobiographical interview. We conducted these tasks individually and then collaboratively two weeks later. Across each of the tasks, although some couples demonstrated collaborative inhibition, others demonstrated collaborative facilitation. We identified a number of factors that predicted collaborative success, in particular, group-level strategy use. Our results show that collaboration may help or hinder memory, and certain interactions are more likely to produce collaborative benefits. (shrink)

There is a popular and widely accepted version of the precautionary principle which may be expressed thus: “If you are in a hole—stop digging!”. Tom Baldwin, as Deputy Chair of the Human Fertilisation and Embryology Authority , may be excused for rushing to the defence of the indefensible,1 the HFEA’s sex selection report,2 but not surely for recklessly abandoning so prudent a principle. Baldwin has many complaints about my misrepresenting the HFEA and about my supposed elitist contempt for public opinion; (...) readers of this exchange will decide for themselves.REDRAFTING THE REPORTBaldwin begins with a piece of wishful thinking:"Harris objects that in this recommendation “an absurdly high standard of caution is employed”, since a theoretical risk is associated with almost all medical procedures. This objection is misplaced: as paragraph 142 of the report indicates, the phrase “theoretical risk” is to be understood here in the light of the earlier discussion of the risks arising from the fact that flow cytometry exposes sperm to laser energy, a procedure which is known to be liable to damage DNA."Paragraph 142 does not make that clear. It does indeed refer back to a set of earlier paragraphs but these give, if anything, an upbeat assessment of the safety of flow cytometry. Paragraph 121 states: “However whilst potentially less intrusive, and with potentially lower risk to the health of patients, flow cytometry …” .2 But even if the overall burden of the report does indicate unresolved fears, the standard is still absurdly high. However, so far from endorsing the report’s judgement that flow cytometry has “potentially lower risk to the health of patients”, Baldwin now regards the risk of flow cytometry as “serious”1:"Since the application of flow cytometry to humans is a new procedure, the risk of … ".

My critics in this symposium illustrate one principle and three fallacies of disability studies. The principle, which we all share, is that all persons are equal and none are less equal than others. No disability, however slight, nor however severe, implies lesser moral, political or ethical status, worth or value. This is a version of the principle of equality. The three fallacies exhibited by some or all of my critics are the following: Choosing to repair damage or dysfunction or to (...) enhance function, implies either that the previous state is intolerable or that the person in that state is of lesser value or indicates that the individual in that state has a life that is not worthwhile or not thoroughly worth living. None of these implications hold. Exercising choice in reproduction with the aim of producing children who will be either less damaged or diseased, or more healthy, or who will have enhanced capacities, violates the principle or equality. It does not. Disability or impairment must be defined relative either to normalcy, “normal species functioning”, or “species typical functioning”. It is not necessarily so defined. (shrink)

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

In the eighth chapter of the Bodhicaryāvatāra, the Buddhist philosopher Śāntideva has often been interpreted as offering an argument that accepting the ultimate nonexistence of the self (anātman) rationally entails a commitment to altruism, the view that one should care equally for self and others. In this essay, I consider reconstructions of Śāntideva’s argument by contemporary scholars Paul Williams, Mark Siderits and John Pettit. I argue that all of these various reconfigurations of the argument fail to be convincing. This suggests (...) that, for Madhyamaka Buddhists, an understanding of anātman does not entail acceptance of the Bodhisattva path, but rather is instrumental to achieving it. Second, it suggests the possibility that in these verses, Śāntideva was offering meditational techniques, rather than making an argument for altruism from the premise of anātman. (shrink)

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

In this enlightening book, Sam Harris argues that free will is an illusion but that this truth should not undermine morality or diminish the importance of social and political freedom; indeed, this truth can and should change the way we think about some of the most important questions in life.

During the past few decades, engineering ethics has been oriented towards protecting the public from professional misconduct by engineers and from the harmful effects of technology. This “preventive ethics” project has been accomplished primarily by means of the promulgation of negative rules. However, some aspects of engineering professionalism, such as (1) sensitivity to risk (2) awareness of the social context of technology, (3) respect for nature, and (4) commitment to the public good, cannot be adequately accounted for in terms of (...) rules, certainly not negative rules. Virtue ethics is a more appropriate vehicle for expressing these aspects of engineering professionalism. Some of the unique features of virtue ethics are the greater place it gives for discretion and judgment and also for inner motivation and commitment. Four of the many professional virtues that are important for engineers correspond to the four aspects of engineering professionalism listed above. Finally, the importance of the humanities and social sciences in promoting these virtues suggests that these disciplines are crucial in the professional education of engineers. (shrink)

Is there such a thing as a social conception of disability? Recently two writers in this journal have suggested not only that there is a coherent social conception of disability but that all non-social conceptions, or “medical models” of disability are fatally flawed. One serious and worrying dimension of their claims is that once the social dimensions of disability have been resolved no seriously “disabling” features remain. This paper examines and rejects conceptions of disability based on social factors but notes (...) that physical and mental conditions which disadvantage the individual have social dimensions.

Bayesian probability has recently been proposed as a normative theory of argumentation. In this article, we provide a Bayesian formalisation of the ad Hitlerum argument, as a special case of the ad hominem argument. Across three experiments, we demonstrate that people's evaluation of the argument is sensitive to probabilistic factors deemed relevant on a Bayesian formalisation. Moreover, we provide the first parameter-free quantitative evidence in favour of the Bayesian approach to argumentation. Quantitative Bayesian prescriptions were derived from participants' stated subjective (...) probabilities (Experiments 1 and 2), as well as from frequency information explicitly provided in the experiment (Experiment 3). Participants' stated evaluations of the convincingness of the argument were well matched to these prescriptions. (shrink)

It appears that utilitarian arguments in favor of moral vegetarianism cannot justify a complete prohibition of eating meat. This is because, in certain circumstances, forgoing meat will prevent no pain, and so, on utilitarian grounds, we should be opportunistic carnivores rather than moral vegetarians. In his paper, ‘Puppies, pigs, and people: Eating meat and marginal cases,’ Alastair Norcross argues that causal impotence arguments like these are misguided. First, he presents an analogous situation, the case of chocolate mousse a-la-bama, in order (...) to argue that we, individually, are not causally impotent. Second, Norcross offers a threshold argument in which he argues that while we may individually be causally impotent, when we adopt moral vegetarianism in concert with others, we become causally potent in preventing harms by factory farming. We argue that Norcross's responses ultimately fail to address the causal impotence objection. The former argument fails because it vastly oversimplifies the world in which we find ourselves. Given the size of factory farming, the reasonable conclusion is that we are in fact powerless to prevent harms to animals in factory farms in many or most cases. The latter argument fails because even if collective action will have an impact on factory farming, this does not provide us with an argument against being carnivores in certain circumstances.

Cloning - few words have as much potential to grip our imagination or grab the headlines. No longer the stuff of science fiction or Star Wars - it is happening now. Yet human cloning is currently banned throughout the world, and therapeutic cloning banned in many countries. In this highly controversial book, John Harris does a lot more than ask why we are so afraid of cloning. He presents a deft and informed defence of human cloning, carefully exposing the (...) rhetorical and highly dubious arguments against it. He begins with an introduction to what a human clone is, before tackling some of the most common and frequently bizarre criticisms of cloning: Is it really wicked? Can we regulate it? What about the welfare of cloned children? Does it turn human beings into commodities? Dismissing one by one some of the myths about human cloning, in particular that it is degrading and unsafe, he astutely argues that some of our most cherished values, such as the freedom to start a family and the freedom from state control, actually support the case for human cloning. Offering a brave and lucid insight into this ethical minefield, John Harris at last shows that far from ending the diversity of human life or creating a race of super-clones, cloning has the power to improve and heal human life.

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

Some philosophers regard it as a serious possibility that we now exist within a simulation. That this hypothesis is somewhat probable has been defended extensively by Nick Bostrom. Notably, Bostrom does not defend the conclusion that we inhabit a simulation, but rather the disjunctive conclusion that the human species is very likely to die out before reaching a ‘posthuman stage’, that posthuman civilizations are extremely unlikely to run significant numbers of simulations, or that we almost certainly inhabit a simulation. Bostrom (...) argues that there is no basis for strongly favouring one of these alternatives over its counterparts. The upshot is that it is fairly probable that we inhabit a simulation. I argue that posthuman civilizations are likely to be unwilling to run significant numbers of simulations, thereby undermining the case for assigning a somewhat high probability to the hypothesis that we live in a simulation.

This article explores the defense Indian Buddhist texts make in support of their conceptions of lives that are good for an individual. This defense occurs, largely, through their analysis of ordinary experience as being saturated by subtle forms of suffering . I begin by explicating the most influential of the Buddhist taxonomies of suffering: the threefold division into explicit suffering , the suffering of change , and conditioned suffering . Next, I sketch the three theories of welfare that have been (...) most influential in contemporary ethical theory. I then argue that Buddhist texts underdetermine which of these theories would have been accepted by ancient Indian Buddhists. Nevertheless, Buddhist ideas about suffering narrow the shape any acceptable theory of welfare may take. In my conclusion, I argue that this narrowing process itself is enough to reconstruct a philosophical defense of the forms of life endorsed in Buddhist texts. (shrink)

What makes it the case that an utterance constitutes an illocutionary act of a given kind? This is the central question of speech-act theory. Answers to it—i.e., theories of speech acts—have proliferated. Our main goal in this chapter is to clarify the logical space into which these different theories fit. -/- We begin, in Section 1, by dividing theories of speech acts into five families, each distinguished from the others by its account of the key ingredients in illocutionary acts. Are (...) speech acts fundamentally a matter of convention or intention? Or should we instead think of them in terms of the psychological states they express, in terms of the effects that it is their function to produce, or in terms of the norms that govern them? In Section 2, we take up the highly influential idea that speech acts can be understood in terms of their effects on a conversation’s context or “score”. Part of why this idea has been so useful is that it allows speech-act theorists from the five families to engage at a level of abstraction that elides their foundational disagreements. In Section 3, we investigate some of the motivations for the traditional distinction between propositional content and illocutionary force, and some of the ways in which this distinction has been undermined by recent work. In Section 4, we survey some of the ways in which speech-act theory has been applied to issues outside semantics and pragmatics, narrowly construed. (shrink)
