Prudential hedonism has been beset by many objections, the strength and number of which have led most modern philosophers to believe that it is implausible. One objection in particular, however, is nearly always cited when a philosopher wants to argue that prudential hedonism is implausible—the experience machine objection to hedonism. This paper examines this objection in detail. First, the deductive and abductive versions of the experience machine objection to hedonism are explained. Following this, the contemporary responses to each version of (...) the argument are assessed and the deductive version is argued to be relatively ineffective compared to the abductive version. Then, a taxonomy of the contemporary critical responses to the abductive version is created. Consideration of these responses shows that the abductive version of the objection is fairly powerful, but also that one type of response seems promising against it. This response argues that experience machine thought experiments seem to elicit judgments that are either too biased to be used as evidence for the objection or not obviously in favour of reality. It is argued that only this type of refutation seems likely to convince proponents of the abductive version that the objection is much weaker than they believe it to be. Finally, it is suggested that more evidence is required before anything definitive can be said on the matter. (shrink)

This paper is a warning that objections based on thought experiments can be misleading because they may elicit judgments that, unbeknownst to the judger, have been seriously skewed by psychological biases. The fact that most people choose not to plug in to the Experience Machine in Nozick’s (1974) famous thought experiment has long been used as a knock-down objection to hedonism because it is widely thought to show that real experiences are more important to us than pleasurable experiences. This paper (...) argues that the commonplace choice to remain in reality when offered a life in the Experience Machine is best explained by status quo bias – the irrational preference for things to remain the same. An alternative thought experiment, empirical evidence, and discussion of how psychological biases can affect our judgments are provided to support this argument. (shrink)

Experience machines, popularized in print by Robert Nozick and on the screen by the Wachowskis’ film The Matrix, provide highly or perfectly realistic experiences that are more pleasant and less painful than those generated in real life.1 The recent surge in virtual reality and neuro-prosthetic technologies is making the creation of real-world experience machines seem inevitable and perhaps imminent.2 Given the likelihood of the near-future availability of such machines, it behooves ethicists to consider the moral status of their potential uses. (...) In this chapter, we investigate the use of experience machines in palliative and end-of-life care situations. We pair up various kinds of experience machines with patients in a range of conditions, to illuminate the moral problems and benefits of using experience machines in this way. We argue that the use of Nozickian experience machines to treat patients in most conditions would be morally problematic, most notably for the negative effects on patients’ characters and real-world relationships. Informed by this initial moral analysis, we describe an experience machine that is more closely related to a virtual reality game, and argue that it can avoid the moral problems encountered by Nozickian experience machines. In fact, we argue that this new kind of experience machine could improve some patients’ characters and relationships with real-world people. We conclude that some kinds of experience machines could benefit many patients, especially those in extreme pain and those not in the position to meaningfully interact with their loved ones in reality. We also note that certain kinds of experience machines could be useful for religious people, for whom the range of palliative and end-of-life care options is often thought to be relatively narrow.

The term "hedonism," from the Greek word ἡδονή (hēdonē) for pleasure, refers to several related theories about what is good for us, how we should behave, and what motivates us to behave in the way that we do. All hedonistic theories identify pleasure and pain as the only important elements of whatever phenomena they are designed to describe. If hedonistic theories identified pleasure and pain as merely two important elements, instead of the only important elements of what they are describing, (...) then they would not be nearly as unpopular as they all are. However, the claim that pleasure and pain are the only things of ultimate importance is what makes hedonism distinctive and philosophically interesting. (shrink)

In this paper, prediction markets that encourage traders to bet on matters of life and death are used to explore the varieties and dynamics of moral repugnance. We define moral repugnance as morally charged feelings of revulsion that correspond (correctly, incorrectly, and indeterminately) to moral reasons and contexts. Rich variations of moral repugnance and their dynamic qualities are presented by investigating the contextual frames in which they arise. These contextual frames constitute interacting conditions composed of information about states of affairs, (...) moral reasons, and feelings of revulsion. Through careful study of two medical prediction markets that encourage betting on death, we can observe the interaction between these causal conditions to see how the varieties of moral repugnance emerge. We also present three interesting results that arise from analyzing the dynamics of moral repugnance in response to prediction markets. First, a prediction market can elicit several conflicting types of moral repugnance at the same time. Second, moral indeterminacy can arise in two different ways when judging prediction markets. Finally, some prediction markets can generate a moral endogeneity problem, a disruptive feedback loop between a given prediction market and the morally relevant outcome it predicts. (shrink)

Naturalist theories of the meaning of life are sometimes criticised for not setting the bar high enough for what counts as a meaningful life. Tolstoy’s version of this criticism is that Naturalist theories do not describe really meaningful lives because they do not require that we connect our finite lives with the infinite. Another criticism of Naturalist theories is that they cannot adequately resolve the Absurd—the vast difference between how meaningful our actions and lives appear from subjective and objective viewpoints. (...) This article proposes a novel view, Optimistic Naturalism, in order to refute these criticisms. Optimistic Naturalism is the view that scientific and technological advancement might allow us to lead Truly Meaningful lives in a purely physical universe by enabling our actions, which we find meaningful partly because they might have particular infinite consequences, to actually have infinite consequences for life. The central tenets of Optimistic Naturalism are Infinite Consequence and Scientific Optimism. By explaining how the correct connection of the subjective and objective meaning of actions can result in True Meaning, Infinite Consequence provides a theoretical blueprint for resolving the Absurd. Scientific Optimism provides reason to think that it is possible to follow that blueprint in a purely physical universe. Therefore, when taken together, these two principles provide relatively plausible reasons to think that at least one kind of Naturalist theory can connect the finite with the infinite in a meaningful way and resolve the Absurd.

Predicting terrorist attacks with prediction markets has been accused of being immoral. While some of these concerns are about the likely effectiveness of prediction markets on terrorism (PMsoT), this paper discusses the three main reasons why even effective prediction markets on terrorism might be considered immoral. We argue that these three reasons establish only that PMsoT cause offense and/or fleeting mild harm, and that, even taken together, they do not constitute serious harm. The moral issues considered are that PMsoT: 1) (...) create character-affecting perverse incentives, 2) desensitise society to tragic events, and 3) disrespect important ideals. In addition to arguing against the force of these three potential moral problems, it is also argued that societies and governments already endorse intelligence-gathering methods that are clearly more immoral than PMsoT in the relevant respects. We also argue that some circumstances require governments to cause non-serious harm to some people in order to protect and promote the rights and welfare of its citizens. We conclude that a government’s obligation to protect and promote the rights and welfare of its citizens outweighs the non-serious harm that could be caused by effective PMsoT. As a result, we recommend that the likelihood of PMsoT being effective is investigated more closely. (shrink)

Prediction markets designed to predict terrorism through traders’ investments on the likelihood of specific terrorist attacks are, strictly speaking, enabling those traders to bet on terrorism. Betting on terrorist attacks, like some other forms of betting on death, has been accused of being repugnant. In this paper, it is argued that while government-backed effective intelligence-gathering prediction markets on terrorism (PMsoT) might elicit feelings of repugnance, those feelings are likely to be misguided. The feelings of repugnance arise because PMsoT are assumed (...) to be associated with terrorism in encouraging and endorsing ways and with human death in a disrespectful way. However, it is argued that these feelings of repugnance are misguided in the case of government-backed effective intelligence-gathering PMsoT because the purpose and effect of such prediction markets, and (on balance) the trading they encourage, is to prevent and renounce terrorism and show respect for matters of life and death.

Real-world policy decisions involve trade-offs. Sometimes the trade-offs involve both the efficacy and morality of potential policies. In this chapter, the morality and likely efficacy of hiring one more spy to help anti-terrorist intelligence gathering efforts is compared to the morality and likely efficacy of implementing a prediction market on terrorism. Prediction markets on terrorism allow registered traders to buy and sell shares in predictions about terrorism-related real-world events. The comparison at the heart of this chapter is based on the (...) assumption that it would cost about $5 million to bankroll the prediction market project, or to establish another spy, including equipment and head office support, for 15 years. The comparison reveals that implementing a prediction market on terrorism is likely to be more efficacious and less morally problematic than hiring one more spy. (shrink)

So you‘re leaving the cinema—you've just been blown away by Inception—and your mind is buzzing. There is a buzz around you too. Everyone‘s asking each other: ‗Does Cobb‘s spinning top fall?‘ Throughout Inception, Cobb has been struggling to achieve two things: to get back home so he can see his kids again and to keep a grip on reality in the process. What ends up happening to Cobb‘s totem bears on both of these struggles. So, most people who watch Inception (...) think that the whole point of the movie hinges on whether or not Cobb‘s top keeps spinning. Unfortunately for most people, they missed the point! The correct answer to 'Does Cobb‘s spinning top fall?‘ is: 'Who cares!‘ The truth, and in my opinion the main point of Inception, is that reality doesn't really matter. (shrink)

In this chapter we first discuss the main principles of justice and note the standard objections to them, which we believe necessitate a hybrid approach. The hybrid account we defend is primarily based on the distributive principle of sufficientarianism, which we interpret as the idea that each country should have the means to provide a minimally decent quality of life for each of its citizens. We argue that sufficientarian considerations give good reason to think that what we call the ‘ability (...) to pay objection’ should be taken much more seriously in this debate. Following this, our account emphasises what we believe are the two most important moral desiderata in any attempt to distribute responsibility for dealing with climate change: the ability to mitigate the problem and the making of culpable contributions to the problem. After noting that our proposal includes enough detail to be a useful start for policy makers, we defend our account against some potential objections. (shrink)

In his provocative “Can We Test the Experience Machine?”, Basil Smith argues that we should recognise a limit on experimental philosophy. In this response to Smith, I will argue that his limit does not prevent us from usefully testing most experience machine thought experiments, including De Brigard‟s inverted experience machine scenarios. I will also argue that, if taken seriously, Smith‟s limit has far-reaching consequences for traditional (non-experimental) philosophy as well.

There are enigmas of defining happiness and of discerning what it is that really makes a life go well for someone – topics that positive psychologists have not adequately addressed to date. And this is despite the fact that Ed Diener sees positive psychology as “the endeavour by scientists to answer the classic question posed by philosophers: What is the good life?” What is rarely mentioned by positive psychologists is that, depending on how the specific happiness questions are worded, they (...) can adopt what philosophers see as radically divergent conceptions of happiness.

This chapter provides a brief historical overview of western philosophical views about human well-being from the eighth century BCE to the middle of the twentieth century. Different understandings of the concept of well-being are explained, including our preferred understanding of well-being as the subjective states and objective conditions that make our lives go well for us. While this review is necessarily incomplete, we aim to discuss some of the most salient and influential contributions to our subject. To that end, we (...) discuss some key views from ancient Greece, including the aristocratic values that were considered central to leading a good life, notions of personal and more expansive harmony as they key to well-being, and the idea that the experience of pleasure is all we should really care about. We also explain some of the major religious conceptions of the good life, and their progression through the middle ages and beyond. More recent secular conceptions of wellbeing, including several views on the importance of personal and public happiness. Finally, we discuss views to the effect that happiness is not enough for the good life and that we should strive for loftier goals. (shrink)

In Solo: A Star Wars Story, the debonair Lando Calrissian is clearly in love with the artificially intelligent droid L3‐37. There are lots of friendships between droids and humans in Star Wars. This chapter looks at the relationship between Lando and L3‐37 in Solo and argues that they exhibit all the hallmarks not just of friendship, but of love. A friendship between people who both seek to gain from the relationship is one of utility, while a friendship between people who (...) simply enjoy each other's company is one of pleasure. Droids are the kinds of beings that can be good friends, as is clearly supported throughout the Star Wars canon. One potential concern is that droids smarter than humans might take advantage of an inferior organic life form by having a sexual relationship with them. (shrink)

PrécisThe administration of Pre-Mortem Interventions (PMIs) to preserve the opportunity to donate, to assess the eligibility to donate, or to optimize the outcomes of donation and transplantation are controversial as they offer no direct medical benefit and include at least the possibility of harm to the still-living patient. In this article, we describe the legal analysis surrounding consent to PMIs, drawing on existing legal commentary and identifying key legal problems. We provide an overview of the approaches in several jurisdictions that (...) have chosen to explicitly address PMIs within codified law. We then provide, as an example, a detailed exploration of how PMIs are likely to be addressed in one jurisdiction where general medical consent law applies because there is no specific legislation addressing PMIs — the province of Ontario in Canada.

En décembre 2007, Jacqueline Hamesse a fêté son 65ème anniversaire, puis a accédé à l’éméritat en 2008. Nombreux sont les collègues et amis qui ont souhaité marquer ces dates en rendant hommage à son dévouement aux études médiévales, que ce soit dans l’enseignement et la recherche ou pour la création et le développement d’institutions internationales dans ce domaine, sans oublier les efforts déployés pour l’édition de nombreux ouvrages collectifs et l’organisation de diverses rencontres scientifiques. Nous avons donc décidé de lui (...) dédier ce volume d’études intitulé «Florilegium mediaevale». L’ouvrage comprend des études concernant l’un des quatre thèmes suivants: les textes philosophiques dans leur contexte et leur support matériel, les instruments travail ainsi que le vocabulaire des textes philosophiques. En effet, ce sont des domaines qui ont surtout retenu son attention depuis de nombreuses années et dans lesquels elle a apporté des contributions significatives à la recherche. Contributions de: L-J.

Les oeuvres de Gersonide (Levi b. Gershom ou Gerson, Leon de Bagnols, philosophe juif provencal 1288-1344) portent essentiellement sur quatre domaines: les commentaires qu'il a consacres aux commentaires d'Averroes, les questions philosophiques et theologico-philosophiques (livres I a IV, VI des Guerres du Seigneur), les commentaires biblioques et des travaux astronomiques (dont le livre V des Guerres). Dans les trois premiers domaines, la maniere dont il a travaille, l'ordonnancement des idees et leur mise en oeuvre sont ici compares a ceux qui (...) furent utilises par ses contemporains scolastiques. Alors que son activite astronomique a amene Gersonide a la frequentation des savants de la cour du Pape a Avignon, il ne cite, dans les oeuvres etudiees, aucun auteur ni aucun texte latin. La maniere dont Gersonide fait de la philosophie, sa methode d'etude et de resolution des problemes, sa conception de l'exegese biblioque comme science et les procedes adoptes dans les commentaires bibliques le rapprochent cependant du monde latin intellectuel de son temps. Ce sont ces ressemblances, mais aussi les dissemblances, qui sont discutees ici. (shrink)

Can we test philosophical thought experiments, such as whether people would enter an experience machine or would leave one once they are inside? Dan Weijers argues that since 'rational' subjects (e.g. students taking surveys in college classes) are believable, we can do so. By contrast, I argue that because such subjects will probably have the wrong affect (i.e. emotional states) when they are tested, such tests are almost worthless. Moreover, understood as a general policy, such pretend testing would ruin (...) the results of most psychological tests, such as those of helping behavior, attitudes to authority, moral transgressions, etc. However, I also argue that certain philosophical thought experiments do not require us to have as much (or any) affect to understand them, or to elicit intuitions, and so can be tested. Generally, experimental philosophy must adhere to this limit, on pain of offering vacuous results. (shrink)

Surprises are important in our everyday lives as well as in our scientific and philosophical theorizing—in psychology, information theory, cognitive-neuroscience, philosophy of science, and confirmation theory. Nevertheless, there is no satisfactory theory of what makes something surprising. It has long been acknowledged that not everything unexpected is surprising. The reader had no reason to expect that there will be exactly 190 words in this abstract and yet there is nothing surprising about this fact. We offer a novel theory that explains (...) when and why an unexpected fact is surprising. We distinguish between descriptive and normative notions of what is surprising; clarify the sense in which surprising facts are unexpected; and, finally, develop and defend the significance account of surprise, according to which a fact is surprising to an agent if and to the extent that it is both unexpected and significant to the agent. Since a surprising fact can be significant to an agent in various ways—personal, moral, epistemic, and aesthetic—surprise is not merely or primarily epistemic. Fitting surprise reflects more than a person’s view of what is; it reflects a person’s view of what is significant. (shrink)

Motivated by examples, many philosophers believe that there is a significant distinction between states of affairs that are striking and therefore call for explanation and states of affairs that are not striking. This idea underlies several influential debates in metaphysics, philosophy of mathematics, normative theory, philosophy of modality, and philosophy of science but is not fully elaborated or explored. This paper aims to address this lack of clear explanation first by clarifying the epistemological issue at hand. Then it introduces an (...) initially attractive account for strikingness that is inspired by the work of Paul Horwich and adopted by a number of philosophers. The paper identifies two logically distinct accounts that have both been attributed to Horwich and then argues that, when properly interpreted, they can withstand former criticisms. The final two sections present a new set of considerations against both Horwichian accounts that avoid the shortcomings of former critiques. It remains to be seen whether an adequate account of strikingness exists. (shrink)

This book argues that political libertarianism can be grounded in widely shared, everyday moral beliefs--particularly in strictures against shifting our burdens onto others. It also seeks to connect these philosophical arguments with related work in economics, history, and politics for a wide-ranging discussion of political economy.

Humans have two kinds of beliefs, intuitive beliefs and reflective beliefs. Intuitive beliefs are a fundamental category of cognition, defined in the architecture of the mind. They are formulated in an intuitive mental lexicon. Humans are also capable of entertaining an indefinite variety of higher‐order or‘reflective’propositional attitudes, many of which are of a credat sort. Reasons to hold reflective beliefs are provided by other beliefs that describe the source of the reflective belief as reliable, or that provide an explicit argument (...) in favour of the reflective belief. The mental lexicon of reflective beliefs includes not only intuitive, but also reflective concepts. (shrink)

This study focuses on the effects of socially responsible human resource management practices on female employees’ turnover intentions and the moderating effect of supervisor gender on this relationship. With a sample of 212 female employees from eight different industries in Finland, the results indicate that SR-HRM practices promoting equal career opportunities and work–family integration play a significant role in reducing women's turnover intentions. The study adds to the academic discourse of corporate social responsibility by highlighting the impact of the organizational-level (...) HRM determinants on the individual-level outcome. In addition, supervisor gender makes a difference in the studied relationship: female supervisors have a stronger and more significant impact on the relationship than male supervisors. Our findings suggest that organizational measures which support work–family integration should be taken seriously to decrease female employees’ turnover intentions. Male supervisors could adopt some gender-incongruent leadership behaviors, such as individualized emotional concern and caring when dealing with female employees. In the future, other gender combinations in the supervisor–employee relationship would merit research. (shrink)

The dominant language of politics in the United States has been political individualism, with minimal restrictions on property and personal, voluntary conduct. But there are second languages of community that stress cooperation and group action. These second languages include the constitutional tradition for public health. Public health offers a community justification for paternalistic measures that, for example, discourage smoking or require seatbelts.

Premodern Buddhists are sometimes characterized as veritable "mind scientists" whose insights anticipate modern research on the brain and mind. Aiming to complicate this story, Dan Arnold confronts a significant obstacle to popular attempts at harmonizing classical Buddhist and modern scientific thought: since most Indian Buddhists held that the mental continuum is uninterrupted by death, they would have no truck with the idea that everything about the mental can be explained in terms of brain events. Nevertheless, a predominant stream of Indian (...) Buddhist thought, associated with the seventh-century thinker Dharmakirti, turns out to be vulnerable to arguments modern philosophers have leveled against physicalism. By characterizing the philosophical problems commonly faced by Dharmakirti and contemporary philosophers such as Jerry Fodor and Daniel Dennett, Arnold seeks to advance an understanding of both first-millennium Indian arguments and contemporary debates on the philosophy of mind. The issues center on what modern philosophers have called _intentionality_--the fact that the mind can be about other things. Tracing an account of intentionality through Kant, Wilfrid Sellars, and John McDowell, Arnold argues that intentionality cannot, in principle, be explained in causal terms. Elaborating some of Dharmakirti's central commitments, Arnold shows that despite his concern to refute physicalism, Dharmakirti's causal explanations of the mental mean that modern arguments from intentionality cut as much against his project as they do against physicalist philosophies of mind. This is evident in the arguments of some of Dharmakirti's contemporaneous Indian critics, whose critiques exemplify the same logic as modern arguments from intentionality. Elaborating these various strands of thought, Arnold shows that seemingly arcane arguments among first-millennium Indian thinkers can illuminate matters still very much at the heart of contemporary philosophy.

According to cognitive psychologists, moral decision-making is a dual-process phenomenon involving two types of cognitive processes: explicit reasoning and implicit intuition. Moral development involves training and integrating both types of cognitive processes through a mix of instruction, practice, and reflection. Serious games are an ideal platform for this kind of moral training, as they provide safe spaces for exploring difficult moral problems and practicing the skills necessary to resolve them. In this article, we present Morality Play, a model for the (...) design of serious games for ethical expertise development based on the Integrative Ethical Education framework from moral psychology and the Lens of the Toy model for serious game design.

How should modern medicine's dramatic new powers to sustain life be employed? How should limited resources be used to extend and improve the quality of life? In this collection, Dan Brock, a distinguished philosopher and bioethicist and co-author of Deciding for Others (Cambridge, 1989), explores the moral issues raised by new ideals of shared decision making between physicians and patients. The book develops an ethical framework for decisions about life-sustaining treatment and euthanasia, and examines how these life and death decisions (...) are transformed in health policy when the focus shifts from what is best for a patient to what is just for all patients. Professor Brock combines acute philosophical analysis with a deep understanding of the realities of clinical health policy. This is a volume for philosophers concerned with medical ethics, health policy professionals, physicians interested in bioethics, and undergraduate courses in biomedical ethics. (shrink)

In _Buddhists, Brahmins, and Belief_, Dan Arnold examines how the Brahmanical tradition of Purva Mimamsa and the writings of the seventh-century Buddhist Madhyamika philosopher Candrakirti challenged dominant Indian Buddhist views of epistemology. Arnold retrieves these two very different but equally important voices of philosophical dissent, showing them to have developed highly sophisticated and cogent critiques of influential Buddhist epistemologists such as Dignaga and Dharmakirti. His analysis--developed in conversation with modern Western philosophers like William Alston and J. L. Austin--offers an innovative (...) reinterpretation of the Indian philosophical tradition, while suggesting that pre-modern Indian thinkers have much to contribute to contemporary philosophical debates. In logically distinct ways, Purva Mimamsa and Candrakirti's Madhyamaka opposed the influential Buddhist school of thought that emphasized the foundational character of perception. Arnold argues that Mimamsaka arguments concerning the "intrinsic validity" of the earliest Vedic scriptures are best understood as a critique of the tradition of Buddhist philosophy stemming from Dignaga. Though often dismissed as antithetical to "real philosophy," Mimamsaka thought has affinities with the reformed epistemology that has recently influenced contemporary philosophy of religion. Candrakirti's arguments, in contrast, amount to a principled refusal of epistemology. Arnold contends that Candrakirti marshals against Buddhist foundationalism an approach that resembles twentieth-century ordinary language philosophy--and does so by employing what are finally best understood as transcendental arguments. The conclusion that Candrakirti's arguments thus support a metaphysical claim represents a bold new understanding of Madhyamaka. (shrink)

A number of philosophers have recently claimed that intrinsicality can be analysed in terms of the metaphysical notion of grounding. Since grounding is a hyperintensional notion, accounts of intrinsicality in terms of grounding, unlike most other accounts, promise to be able to discriminate between necessarily coextensive properties that differ in whether they are intrinsic. They therefore promise to be compatible with popular metaphysical theories that posit necessary entities and necessary connections between wholly distinct entities, on which it is plausible that (...) there are such properties. This paper argues that this promise is illusory. It is not possible to give an analysis of intrinsicality in terms of grounding that is consistent with these theories. Given an adequate analysis should be compatible with these theories, it follows that it is not possible to analyse intrinsicality in terms of grounding. (shrink)

The claim that the human cognitive system tends to allocate resources to the processing of available inputs according to their expected relevance is at the basis of relevance theory. The main thesis of this chapter is that this allocation can be achieved without computing expected relevance. When an input meets the input condition of a given modular procedure, it gives this procedure some initial level of activation. Input-activated procedures are in competition for the energy resources that would allow them to (...) follow their full course. What determines which of the procedures in competition get sufficient resources to trigger their full operation is the dynamics of their activation. This dynamics depend both on the prior degree of mobilisation of a modular procedure and on the activation that propagates from other active modules. It is quite conceivable also that the mobilisation of some procedures has inhibitory effects on some others. The relevance-theoretic claim is that, at every instant, this dynamics of activation provides rough physiological indicators of expected relevance. The flow of energy in the system is locally regulated by these indicators. As a result, those input-procedure combinations that have the greatest expected relevance are the more likely ones to receive sufficient energy to follow their course. (shrink)

This paper presents a novel approach to the unsupervised learning of syntactic analyses of natural language text. Most previous work has focused on maximizing likelihood according to generative PCFG models. In contrast, we employ a simpler probabilistic model over trees based directly on constituent identity and linear context, and use an EM-like iterative procedure to induce structure. This method produces much higher quality analyses, giving the best published results on the ATIS dataset.

I argue for the merits of studying historical moral revolutions to inform moral and political philosophy. Such a research program is not merely of empirical, historical interest but has normative implications. To explain why, I situate the proposal in the tradition of naturalized epistemology. As Alison M. Jaggar and other scholars have argued, a naturalistic approach is characteristic of much feminist philosophy. Accordingly, I argue that the study of moral revolutions would be especially fruitful for feminist moral and political philosophers.

We present a generative distributional model for the unsupervised induction of natural language syntax which explicitly models constituent yields and contexts. Parameter search with EM produces higher quality analyses than previously exhibited by unsupervised systems, giving the best published unsupervised parsing results on the ATIS corpus. Experiments on Penn treebank sentences of comparable length show an even higher F1 of 71% on nontrivial brackets. We compare distributionally induced and actual part-of-speech tags as input data, and examine extensions to the basic (...) model. We discuss errors made by the system, compare the system to previous models, and discuss upper bounds, lower bounds, and stability for this task. (shrink)

Modern reflection about the good life and the good society has been dominated by a spirit of liberal optimism, according to which people typically know what’s good for them and make prudent choices in pursuit of their interests. As a result, people tend to do best, and pretty well at that, when given the greatest possible freedom to live as they wish. This appealing doctrine rests on a bold assumption about human psychology: namely, that people have a high degree of (...) aptitude for securing their well-being given arbitrarily high levels of “option freedom.” Yet a large body of empirical research suggests that people are systematically prone to make a variety of serious errors in the pursuit of happiness. These errors are probably serious enough to place liberal optimism’s psychological assumptions in doubt. If people do tend to fare best in the option-rich environments traditionally favored by liberal moderns, notably classical economists, this may not be mainly through the prudent exercise of choice. Or perhaps human beings actually benefit from certain constraints or burdens on choice. (shrink)

There are roughly two philosophical literatures on “happiness,” each corresponding to a different sense of the term. One uses ‘happiness’ as a value term, roughly synonymous with well-being or flourishing. The other body of work uses the word as a purely descriptive psychological term, akin to ‘depression’ or ‘tranquility’. An important project in the philosophy of happiness is simply getting clear on what various writers are talking about: what are the important meanings of the term and how do they connect? (...) While the “well-being” sense of happiness receives significant attention in the contemporary literature on well-being, the psychological notion is undergoing a revival as a major focus of philosophical inquiry, following on recent developments in the science of happiness. This entry focuses on the psychological sense of happiness (for the well-being notion, see the entry on well-being). The main accounts of happiness in this sense are hedonism, the life satisfaction theory, and the emotional state theory. Leaving verbal questions behind, we find that happiness in the psychological sense has always been an important concern of philosophers. Yet the significance of happiness for a good life has been hotly disputed in recent decades. Further questions of contemporary interest concern the relation between the philosophy and science of happiness, as well as the role of happiness in social and political decision-making. (shrink)

This paper presents empirical studies and closely corresponding theoretical models of the performance of a chart parser exhaustively parsing the Penn Treebank with the Treebank’s own CFG grammar. We show how performance is dramatically affected by rule representation and tree transformations, but little by top-down vs. bottom-up strategies. We discuss grammatical saturation, including analysis of the strongly connected components of the phrasal nonterminals in the Treebank, and model how, as sentence length increases, the effective grammar rule size increases as regions (...) of the grammar are unlocked, yielding super-cubic observed time behavior in some configurations.
