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)

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.

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)

Robert Nozick's experience machine thought experiment (Nozick's scenario) is widely used as the basis for a ?knockdown? argument against all internalist mental state theories of well-being. Recently, however, it has been convincingly argued that Nozick's scenario should not be used in this way because it elicits judgments marred by status quo bias and other irrelevant factors. These arguments all include alternate experience machine thought experiments, but these scenarios also elicit judgments marred by status quo bias and other irrelevant factors. In (...) this paper, several experiments are conducted in order to create and test a relatively bias-free experience machine scenario. It is argued that if an experience machine thought experiment is used to evaluate internalist mental state theories of well-being, then this relatively bias-free scenario should be used over any of the existing scenarios. Unlike the existing experience machine scenarios, when this new scenario is used to assess internalist mental state theories of well-being, it does not provide strong evidence to refute or endorse them.

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.

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.

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)

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 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)

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.

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)

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)

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)

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.
