In this paper, I reconstruct Robert Nozick's experience machine objection to hedonism about well-being. I then explain and briefly discuss the most important recent criticisms that have been made of it. Finally, I question the conventional wisdom that the experience machine, while it neatly disposes of hedonism, poses no problem for desire-based theories of well-being.

The aim of this investigation is to answer the question of why it is prima facie morally wrong to cause or contribute to the extinction of species. The first potential answer investigated in the book is that other species are instrumentally valuable for human beings. The results of this part of the investigation are that many species are instrumentally valuable for human beings but that not all species are equally valuable in all cases. The instrumental values of different species also (...) have to compete with other human values. Sometimes these other values probably outweigh the value of the continued existence of the species. In general the degree of uncertainty is very high and the precautionaty principle is recommended to deal with these uncertainties. We also found that we have a duty to consider the interests of future generations of human beings and that these duties, in general, speak in favour of preservation. Anthropocentric instrumentalism therefore provides us with rather strong reasons to consider many cases of human caused extinction as prima facie morally wrong. Even so, anthropocentric instrumentalism does not fully account for the moral intuition we set out to investigate. The next potential answer that is investigated in the book is that species have a moral standing in their own right. The result of this part of the investigation is that this idea is highly unlikely, in particular because species cannot have any interests to consider. Anotgher potential answer is that species have intrinsic value in some other meaning that does not imply moral standing. We concluded that it is possible to be subjectively valued as an end and that many species have properties that make them highly suitable for being valued as ends by human beings. Finally, we found that our contributions to the extinction of species in most cases frustrate the interests of many non-human sentient beings. This is true if the species in question is made up of sentient individuals, and it is also true when the species in question is made up of non-sentient individuals that have instrumental value for sentient individuals of other species. There are exceptions to this rule, but all in all it seems that the inclusion of non-human sentient individuals together with us humans as moral objects, in most cases, tip the scale drastically in favour of preservation. The main result of the investigation is that there is not one but several explanations to why it is prima facie morally wrong to contribute to the extinction of species – and all of them are about duties to respect the interests of individual sentient animals, including human beings.

A philosophical discussion of children's well-being in which various existing views of well-being are discussed to determine their implications for children's well-being and a variety of views of children's well-being are considered and evaluated.

The term “virtual reality” was first coined by Antonin Artaud to describe a value-adding characteristic of certain types of theatrical performances. The expression has more recently come to refer to a broad range of incipient digital technologies that many current philosophers regard as a serious threat to human autonomy and well-being. Their concerns, which are formulated most succinctly in “brain in a vat”-type thought experiments and in Robert Nozick's famous “experience machine” argument, reflect a fundamental misunderstanding of the way that (...) such technologies would probably have to work. They also considerably underestimate the positive contributions that virtual reality technologies could make to the growth of human knowledge. Here, we examine and critique Nozick's claim that no reasonable person would want to plug into his hypothetical experience machine in light of a broadly enactivist understanding of how future VR technologies might be expected to function. We then sketch out a tentative theory of the phenomenon of truth in fiction, in order to characterize some of the distinct epistemic opportunities that VR technologies promise to provide. (shrink)

Utilitarianism is the view according to which the only basic requirement of morality is to maximize net aggregate welfare. This position has implications for the ethics of creating and rearing children. Most discussions of these implications focus either on the ethics of procreation and in particular on how many and whom it is right to create, or on whether utilitarianism permits the kind of partiality that child rearing requires. Despite its importance to creating and raising children, there are, by contrast, (...) few sustained discussions of the implications of utilitarian views of welfare for the matter of what makes a child’s life go well. This paper attempts to remedy this deficiency. It has four sections. Section one discusses the purpose of a theory of welfare and its adequacy conditions. Section two evaluates what prominent utilitarian theories of welfare imply about what makes a child’s life go well. Section three provides a sketch of a view about what is prudentially valuable for children. Section four sums things up. (shrink)

Nozick's thought experiment is less effective than is often believed. Certainly, there could be reasons to enter the machine. Possibly, life there might be among the best of all those available. Yet we need to distinguish between two versions. On the first, I retain my beliefs, memories, dispositions, some knowledge. On the second, all these too are determined by the scientists. Nozick alludes to both versions. But only on the first will machine life have appeal.

Money isn’t everything, so what is? Many government leaders, social policy theorists, and members of the general public have a ready answer: happiness. This paper examines an opposing view due to Robert Nozick, which centres on his experience-machine thought experiment. Despite the example's influence among philosophers, the argument behind it is riddled with difficulties. Dropping the example allows us to re-version Nozick's argument in a way that makes it far more forceful - and less dependent on people's often divergent intutions (...) about the experience machine.

Most people's intuitive reaction after considering Nozick's experience machine thought-experiment seems to be just like his: we feel very little inclination to plug in to a virtual reality machine capable of providing us with pleasurable experiences. Many philosophers take this empirical fact as sufficient reason to believe that, more than pleasurable experiences, people care about “living in contact with reality.” Such claim, however, assumes that people's reaction to the experience machine thought-experiment is due to the fact that they value reality (...) over virtual experiences—an assumption that has seldom (if ever) been questioned. This paper challenges that very assumption. I report some experimental evidence suggesting that the intuition elicited by the thought-experiment may be explainable by the fact that people are averse to abandon the life they have been experiencing so far, regardless of whether such life is virtual or real. I use then an explanatory model, derived from what behavioral economists and psychologists call the status quo bias, to make sense of these results. Finally, I argue that since this explanation also accounts for people's reaction toward Nozick's thought-experiment, it would be wrong to take such intuition as evidence that people value being in touch with reality.

This paper is a plea for hedonism to be taken more seriously. It begins by charting hedonism's decline, and suggests that this is a result of two major objections: the claim that hedonism is the 'philosophy of swine', reducing all value to a single common denominator, and Nozick's 'experience machine' objection. There follows some elucidation of the nature of hedonism, and of enjoyment in particular. Two types of theory of enjoyment are outlined-intemalism, according to which enjoyment has some special 'feeling (...) tone'. and externalism, according to which enjoyment is any kind of experience to which we take some special attitude, such as that of desire. lnternalism-the traditional view--is defended against current externalist orthodoxy. The paper ends with responses to the philosophy of swine and the experience machine objections. (shrink)

Desire theories of well-being claim that how well someone’s life goes for them is entirely determined by the fulfilment and frustration of their desires. This thesis considers the viability of theories of this sort. It examines a series of objections that threaten to undermine these views. These objections claim that desire theories of well-being are incorrect because they have implausible implications. I consider four main objections over the course of this thesis. The first claims that these theories are incorrect because (...) they implausibly entail that self-sacrifice does not exist. The second claims that these theories are incorrect because they implausibly entail that severe depression does not diminish the well-being of those afflicted by this condition. The third claims that these theories are incorrect because they have implausible implications about the relative importance of fleeting desires, long-standing desires, and fluctuations in desire strength to well-being. The fourth claims that these theories are incorrect because they fail to capture the intuition that desire fulfilments which leave us disappointed and bereft of feelings of satisfaction do not improve well-being. In each of these cases, I find that desire theories of well-being have sufficient resources to refute these objections. The primary finding of this thesis is that many of the arguments against desire theories of well-being are unsuccessful. A secondary set of findings concern observations about the structure of human psychology. (shrink)

Here I will re-purpose Nozick’s (1974) “Experience Machine” thought experiment against hedonism into an argument against Veritic Epistemic Consequentialism. According to VEC, the right action, epistemically speaking, is the one that results in at least as favorable a ratio of true to false belief as any other action available. A consequence of VEC is that it would be epistemically right to outsource all your cognitive endeavors to a matrix-like “True Belief Machine” that uploads true beliefs through artificial stimulation. Rather than (...) reflecting, inferring or inquiring, all of your beliefs would be the product of updates coming from the machine. This implication of VEC is counter intuitive. I will spend much of the paper considering defensive maneuvers and showing them to be lacking. The problem with going in for the True Belief Machine seems to be that the subject forfeits her autonomy. There has been much work lately on the virtue of intellectual autonomy and some of it has the potential to explain what is epistemically amiss about plugging into the machine. However, I will argue that the proponent of VEC cannot appeal to it without abandoning her preferred order of explanation. (shrink)

There is a strong intuition that a zombie’s life is never good or bad for the zombie. What explains this? In this paper, I consider five possible explanations of the intuition that a zombie’s life is never worth living, plus the option of rejecting the intuition. I point out the considerable costs of each option, though making clear which option strikes me as least problematic.

The two main subjectivist accounts of wellbeing, hedonism and desire-satisfactionism, focus on pleasure and desire (respectively) as the subjective states relevant to evaluating the goodness of a life. In this paper, I argue that another type of subjective state, mood, is much more central to wellbeing. After a general characterization of some central features of mood (§1), I argue that the folk concept of happiness construes it in terms of preponderance of good mood (§2). I then leverage this connection between (...) mood and happiness to argue that having certain mood patterns in one’s life is sufficient for having a good life (§3), and explore their potential necessity for a good life (§4). I close with discussion of the role that mood patterns might play within the three leading philosophical theories of wellbeing: hedonism (§5), desire-satisfactionism (§6), and objective-list theory (§7).

The time has come to consider whether experimental philosophy’s (“x-phi”) early arguments, debates, and conceptual frameworks, that may have worn well in its early days, fit with the diverse range of projects undertaken by experimental philosophers. Our aim is to propose a novel taxonomy for x-phi that identifies four paths from empirical findings to philosophical consequences, which we call the “fourfold route.” We show how this taxonomy can be fruitfully applied even at what one might have taken to be the (...) furthest edges of possible applications of x-phi in metaphysics and formal philosophy. Ultimately, the fourfold route helps us understand a different kind of empirical fact: the development of x-phi itself. (shrink)

Theories of well-being purport to identify the features of lives, and of intervals within lives, in virtue of which some people are high in well-being and others are low in well-being. They also purport to identify the properties that make some events or states of affairs good for a person and other events or states of affairs bad for a person. This article surveys some of the main theories of well-being, with an emphasis on work published since the turn of (...) the century. (shrink)

This volume collects selected papers delivered at the 15th Conference of the International Society for Utilitarian Studies, which was held at Karlsruhe Institute of Technology in July 2018. It includes papers dealing with the past, present, and future of utilitarianism – the theory that human happiness is the fundamental moral value – as well as on its applications to animal ethics, population ethics, and the future of humanity, among other topics.

Prudential hedonism is a school of thought in the philosophy of welfare that says that only pleasure is good for us in itself and only pain is bad for us in itself. This dissertation concerns an especially austere form of prudential hedonism: basic prudential hedonism (BPH). BPH claims that all pleasure is good for us in itself, and all pain is bad for us in itself, without exception; that all pleasures feel fundamentally alike, as do all pains; and that the (...) amount of welfare in a person’s life can (in principle) be calculated just by adding up the amount of pleasure it contains and subtracting the amount of pain. The dissertation presents a positive argument for the claim that pleasures and pains are defined by common phenomenal properties, defends BPH against a battery of objections, and outlines an argument for accepting BPH on the grounds that it is simpler than competing views.

Recent work within such disparate research areas as the epistemology of perception, theories of well-being, animal and medical ethics, the philosophy of consciousness, and theories of understanding in philosophy of science and epistemology has featured disconnected discussions of what is arguably a single underlying question: What is the value of consciousness? The purpose of this paper is to review some of this work and place it within a unified theoretical framework that makes contributions (and contributors) from these disparate areas more (...) visible to one another.

Experientialist accounts of wellbeing are those accounts of wellbeing that subscribe to the experience requirement. Typically, these accounts are hedonistic. In this article I present the claim that hedonism is not the most plausible experientialist account of wellbeing. The value of experience should not be understood as being limited to pleasure, and as such, the most plausible experientialist account of wellbeing is pluralistic, not hedonistic. In support of this claim, I argue first that pleasure should not be understood as a (...) broad term to describe valuable experiences generally. I then analyze responses to the main argument against a monistic view on the value of experience: the philosophy of swine objection. I argue that such responses deviate from the central hedonistic view that only pleasure and pain matter for wellbeing. I then argue that the argument can be avoided on a pluralistic account, and formulate a plausible candidate for an account of pluralistic experientialism, in which, besides pleasure, non-hedonic aspects of experience like novelty, compassion, and aesthetic value also contribute to wellbeing.

While Nozick and his sympathizers assume there is a widespread anti-hedonist intuition to prefer reality to an experience machine, hedonists have marshalled empirical evidence that shows such an assumption to be unfounded. Results of several experience machine variants indicate there is no widespread anti-hedonist intuition. From these findings, hedonists claim Nozick's argument fails as an objection to hedonism. This article suggests the argument surrounding experience machines has been misconceived. Rather than eliciting intuitions about what is prudentially valuable, these intuitive judgements (...) are instead calculations about prudential pay-offs and trade-offs. This position can help explain the divergence of intuitions people have about experience machines. (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)

Philosophers tended to identify happiness with either subjective psychological states or conditions (feelings, emotions or a set of judgments), or with the objective conditions of a life—how well the life is going for the person living it. Each approach captures different but important features of our intuitions, making it difficult to accept either a purely subjective or objective view. This has led some philosophers to suggest that these are not competing accounts of one thing, ‘happiness,’ but accounts of several different (...) things. Others propose that happiness is a matter of possessing both the relevant subjective and objective properties. I think this latter view is right, but that we need to better understand why or how these two elements are important and how they might be linked. In this paper I argue that an affect theory of happiness is best able to reconcile both the subjective and objective strands of our intuitions about happiness. (shrink)

It may seem paradoxical to speak of the ‘goodlife’ for demented elderly. Many people consider dementia to be a life-wrecking disease and nursing homes to be terrible places. Still, it is relevant to ask how we can make life as good as possible for demented nursing home residents. This paper explores what three standard philosophical accounts of well-being — subjective preference theory, objectivist theories, and hedonism — have to say about the good life for demented people. It is concluded that (...) the relevant differences between the various philosophical theories manifest themselves not so much in their general account of the substantial content of ‘the good life’ but in a number of specific controversies. These concern the nature of well-being, the necessity of endorsement by the patient, the value of experience and the need for experiences to be rooted in reality. Moreover, it is argued that further research should pay detailed attention to the process of dementia and to the effects of this process on patients' identities, self-conceptions, capacities, preferences, values and the like, and that a narrative approach which incorporates the factor time may offer a more comprehensive account of the good life for demented elderly.

Robert Nozick's experience machine thought experiment is often considered a decisive refutation of hedonism. I argue that the conclusions we draw from Nozick's thought experiment ought to be informed by considerations concerning the operation of our intuitions about value. First, I argue that, in order to show that practical hedonistic reasons are not causing our negative reaction to the experience machine, we must not merely stipulate their irrelevance (since our intuitions are not always responsive to stipulation) but fill in the (...) concrete details that would make them irrelevant. If we do this, we may see our feelings about the experience machine becoming less negative. Second, I argue that, even if our feelings about the experience machine do not perfectly track hedonistic reasons, there are various reasons to doubt the reliability of our anti-hedonistic intuitions. And finally, I argue that, since in the actual world seeing certain things besides pleasure as ends in themselves may best serve hedonistic ends, hedonism may justify our taking these other things to be intrinsically valuable, thus again making the existence of our seemingly anti-hedonistic intuitions far from straightforward evidence for the falsity of hedonism.

What makes something good for me? Most contemporary philosophers argue that something cannot count as good for me unless I am in some way attracted to it, or take delight in it. However, subjectivist theories of prudential value face difficulties, and there is no consensus about how these difficulties should be resolved. Whether one opts for a hedonist or a desire-satisfaction account of..

Few philosophers today embrace quantitative hedonism, which states that a person’s well-being depends only on the amount of her experienced happiness and suffering. Despite recent attempts to rehabilitate it, most philosophers still consider it untenable. The most influential arguments levelled against it by Mill, Moore, Nozick and Kagan purport to demonstrate that well-being must depend on more than only the amount of experienced happiness and suffering. I argue in this paper that quantitative hedonism can rebut these arguments by pointing out (...) a shared systematic flaw in their argumentative structure. In particular, I argue that they are based on thought experiments that invoke either structurally unreliable intuitions or intuitions that are not in tension to the tenets of quantitative hedonism. While this does not rehabilitate the theory by itself, it shows that the classical arguments against quantitative hedonism provide far less evidence against it than commonly thought. (shrink)

Theories of well-being purport to identify the basic goods and bads whose presence in a person's life determines how well she is faring. Monism is the view that there is only one basic good and one basic bad. Pluralism is the view that there is either more than one basic good or more than one basic bad. In this paper, I give an argument for pluralism that is general in the sense that it does not purport to identify any basic (...) goods or bads. If I am right, then even if you cannot name a single basic good or bad, you can know that pluralism is true. (shrink)

ZusammenfassungDer Hedonismus ist aus der gegenwärtigen Debatte um das gute Leben als ernstzunehmende Position nahezu verschwunden. Die dabei vorherrschende Kritiklinie wirft dem hedonistischen Ansatz ein systematisches Ungenügen vor: Er sei eine zu schlichte Theorie, um all das angemessen abbilden zu können, was ein menschliches Leben zu einem glücklich-gelungenen macht. In einer kritischen Auseinandersetzung mit zwei prominenten Fassungen dieser Kritiklinie – einerseits Carlyles Vorwurf, der Utilitarismus sei eine „Philosophie für Schweine“, und Mills Versuch einer Antwort darauf, andererseits Nozicks Gedankenexperiment der „Erlebnismaschine“ (...) – argumentiere ich dafür, dass dieser Einwand keineswegs das Ende für den Hedonismus bedeuten muss. Ich zeige argumentative Wege auf, mit denen ein zeitgemäßer Hedonismus darauf reagieren kann, die in die grundlegendere These münden, dass der Hedonismus als Theorie des guten Lebens gut daran täte, seine moralphilosophische Unabhängigkeit – insbesondere vom Utilitarismus – zu behaupten.

One widespread argument against the efficacy of subjective well-being as a measure of well-being is the adaptation problem as formulated by Sen and Nussbaum: the phenomenon that people may adapt to deprivation and find satisfaction or happiness in objectively bad circumstances. It is not generally noticed that there are two distinct arguments for why the phenomenon of adaptation is a problem for subjective well-being as a measure of well-being. The Axiological Adaptation Argument is a counter-example to theories of well-being that (...) rely on mental states. The Epistemic Adaptation Argument illustrates that levels of happiness or satisfaction cannot be measured well when people have adapted. I argue that the most serious threat to subjective well-being measures is not the Axiological Argument, but the Epistemic Argument. I reflect on the implications the epistemic problem has for the empirical literature in general, and for research on the phenomenon of adaptation in particular. (shrink)

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)

In refutation of hedonism, Nozick offered a hypothetical thought experiment, known as the Experience Machine. This paper maintains that end-of-life-suffering of the kind that is resistant to state-of-the-art palliation provides a conceptually equal experiment which validates Nozick’s observations and conclusions. The observation that very many terminal patients who suffer terribly do no wish for euthanasia or terminal sedation is incompatible with motivational hedonism. Although irreversible vegetative state and death are equivalently pain-free, very many people loath the former even at the (...) price of the latter. This attitude cannot be accounted for by hedonism. Following these observations, the goals of palliative care are sketched along four circles. The first is mere removal or mitigation of noxious symptoms and suffering. The second targets sufferings that stymie patients’ life-plans and do not allow them to be happy, the third targets sufferings that interfere with their pursuance of other goods (palliation as a primary good). The fourth is the control of sufferings that do not allow the person to benefit from any human good whatsoever (“total pain” or critical suffering). Only in the fourth circle are people hedonists.

In the second half of their recent, critically acclaimed book Unto Others: The Evolution and Psychology of Unselfish Behavior , Elliott Sober and David Sloan Wilson discuss psychological hedonism. This is the view that avoiding our own pain and increasing our own pleasure are the only ultimate motives people have. They argue that none of the traditional philosophical arguments against this view are good, and they go on to present theirownevolutionary biological argument against it. Interestingly, the first half of their (...) book, which is a defense of group selectionism, has received almost all of the attention of those people who have published reactions to the book. No one has published a detailed reaction to the argument of the latter half of the book. In this article, the author explains and critically discusses their evolutionary biological argument against psychological hedonism, concluding that in its current form it is not strong enough to support its conclusion. However, the author goes on to argue that despite recent criticisms of Robert Nozick’s experience-machine argument, it is still a good argument against psychological hedonism. In support of the latter point, the author responds to the objections of Sober and Wilson and to the more recent criticisms offered by Matthew Silverstein.

This thesis is a contribution to the ethical justification for clinical research with children. A research subject’s participation in a trial is usually justified, in part, by informed consent. Informed consent helps to uphold the moral principle of respect for persons. But children’s limited ability to make informed choices gives rise to a problem. It is unclear what, if anything, justifies their participation in research. Some research ethicists propose to resolve this problem by appealing to social utility, proxy consent, arguments (...) explaining why it is permissible to expose children to some harm, and an argument concerning the appropriate balance between research harms and benefits. I argue that each of these is a necessary part of the justification for research with children, but that the argument concerning harms and benefits is under-developed. It relies on the concept of minimal risk, but minimal risk is inadequately justified. I propose an interpretation of minimal risk. I defend the idea that minimal risk should be interpreted according to the risks of daily life. I reject the most prominent defense of daily life, which claims that daily risks are morally relevant because they replace, rather than add to, the risks a child would ordinarily face. Instead, I propose that these risks are part of a reasonable trade-off between personal safety and our ability to pursue meaningful lives. I then examine whose daily life should be captured in the concept of minimal risk. I reject arguments that minimal risk should refer to healthy children or the subjects of the research and propose instead that the referent should be children who are not unduly burdened by their lives. I argue that children are not unduly burdened when they fare well and defend the idea that children fare well when they possess sufficiently high degrees of the substantive goods of childhood. I conclude by analyzing a controversial case study using my interpretation of minimal risk. I draw on this case to argue that my interpretation offers clear guidance for research ethics review and contributes to a determination that is more plausible than its rivals. (shrink)
