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.

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.

In this paper I take some initial steps toward exploring and motivating the suggestion that quality of life and level of well-being do not come to the same thing.

Many philosophers believe that Robert Nozick's experience machine argument poses an insurmountable obstacle to hedonism as a theory of well-being. After an initial attempt to demonstrate that the persuasiveness of this argument rests on a key ambiguity, I argue that the intuitions to which the thought experiment appeals are not nearly as clear as many philosophers suppose they are. I believe that a careful consideration of the origin of those intuitions -- especially in light of the so-called "paradox of hedonism" (...) -- reveals that they can, in fact, fit quite comfortably into a hedonistic theory of well-being.

Theories of individual well‐being fall into three main categories: hedonism, the desire‐fulfilment theory, and the list theory (which maintains that there are some things that can benefit a person without increasing the person's pleasure or desire‐fulfilment). The paper briefly explains the answers that hedonism and the desire‐fulfilment theory give to the question of whether being virtuous constitutes a benefit to the agent. Most of the paper is about the list theory's answer.

What are the limits of well-being? This question nicely captures one of the central debates concerning the nature of the individual human good. For rival theories differ as to what sort of facts directly constitute a person's being well-off. On some views, well-being is limited to the presence of pleasure and the absence of pain. But other views push the boundaries of well-being beyond this, so that it encompasses a variety of mental states, not merely pleasure alone. Some theories then (...) draw the line here, limiting well-being to the presence of the appropriately broadened set of mental states. But still others extend the limits of well-being even further, so that it is constituted in part by facts that are not themselves mental states at all; on such views, well-being is partly constituted by states of affairs that are “external” to the individual's experiences. In this essay, I want to explore some of this debate by focusing on a particular stretch of the dialectic. That is, I want to think hard about a particular connected series of arguments and counterarguments. These arguments – or, at least, the concerns they seek to express – emerge naturally in the give and take of philosophical discussion. Together they make up a rather simple story, whose plot, in very rough terms, is this: first there is an attempt to push the limits of well-being outward, moving from a narrow to a broader conception; then comes the claim that the resulting notion is too broad, and so we must retreat to a narrower conception after all.

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.

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.

It is argued that Nozick's experience machine thought experiment does not pose a particular difficulty for mental state theories of well-being. While the example shows that we value many things beyond our mental states, this simply reflects the fact that we value more than our own well-being. Nor is a mental state theorist forced to make the dubious claim that we maintain these other values simply as a means to desirable mental states. Valuing more than our mental states is compatible (...) with maintaining that the impact of such values upon our well-being lies in their impact upon our mental lives. (shrink)

This volume presents a comprehensive statement in defense of the doctrine known as classical, hedonistic utilitarianism. It is presented as a viable alternative in the search for a moral theory and the claim is defended that we need such a theory. The book offers a distinctive approach and some quite controversial conclusions. Torbjorn Tannsjo challenges the assumption that hedonistic utilitarianism is at variance with common sense morality particularly as viewed through the perspective of the modern feminist moral critique.

What is good, how do we know, and how important is it? In this book, one of our most respected analytical philosophers reorients these questions around the notion of what causes human beings to flourish. Observing that we can sensibly address what is good for plants and animals no less than what is good for people, Kraut applies a general principle to the entire living world: what is good for complex organisms consists in the exercise of their natural powers.

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 experience machine was traditionally thought to refute hedonism about welfare. In recent years, however, the tide has turned: many philosophers have argued not merely that the experience machine doesn't rule out hedonism, but that it doesn't count against it at all. I argue for a moderate position between those two extremes: although the experience machine doesn't decisively rule out hedonism, it provides us with some reason to reject it. I also argue for a particular way of using the experience (...) machine to argue against hedonism – one that appeals directly to intuitions about the welfare values of experientially identical lives rather than to claims about what we value or claims about whether we would, or should, plug into the machine. The two issues are connected: the conviction that the experience machine leaves hedonism unscathed is partly due to neglect of the best way to use the experience machine. (shrink)

A subjective list theory of well-being is one that accepts both pluralism (the view that there is more than one basic good) and subjectivism (the view, roughly, that every basic good involves our favourable attitudes). Such theories have been neglected in discussions of welfare. I argue that this is a mistake. I introduce a subjective list theory called disjunctive desire satisfactionism, and I argue that it is superior to two prominent monistic subjectivist views: desire satisfactionism and subjective desire satisfactionism. In (...) the course of making this argument, I introduce a problem for desire satisfactionism: it cannot accommodate the fact that whenever someone experiences an attitudinal pleasure, his welfare is (other things equal) higher during the pleasure. Finally, I argue that any subjectivist about welfare should find disjunctive desire satisfactionism highly attractive. (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)

Argues that rules should not be evaluated in terms of the numbers of acts of this or that kind that they allow. Then asks whether rules should be assessed in terms of whether they promote equality, fairness, and justice, or whether they give priority to the worst off. Finally, two sections discuss how rule‐consequentialism and contractualism differ as to whether morality contains prohibitions on how humans treat animals and the natural environment.

This is a wide-ranging defense of a distinctive version of hedonistic act utilitarianism. It is plainly written, forthright, and stimulating. Also, it is replete with disputable assertions and arguments. I shall pursue one issue here, after sketching the project of each substantial chapter.

Judgments of well-being across different circumstances and spheres of life exhibit a staggering diversity. Depending on the situation, we use different standards of well-being and even treat it as being constituted by different things. This is true of scientific studies as well as of everyday life. How should we interpret this diversity? I consider three ways of doing so: first, denying the legitimacy of this diversity, second, treating well-being as semantically invariant but differentially realizable, and, third, adopting contextualist semantics for (...) well-being expressions. I reject the first option on the grounds that it is unable to make sense of much of everyday and scientific linguistic practices, and also because it makes the category of well-being insignificant or even otiose for practical purposes. We should thus pick between the second and the third options. I argue that contextualism about well-being is more plausible and faces fewer objections than the differential realization view. I conclude with a discussion of other features of contextualism: it does not imply that well-being is relative to individual taste, it need not result in eliminativism about well-being, nor in scepticism about a general theory of well-being. It does not commit us to an “anything goes” approach, nor does it threaten anarchy and miscommunication. (shrink)

According to Robert Nozick's famous "experience machine" argument, we would not choose to spend our lives with our brains connected to a machine that could deliver any set of experiences we desire. Because most of us would decline to live any variant of life in "The Matrix," so to speak, the thought experiment purportedly demonstrates that we value aspects of life other than just subjective experiences. I argue that while most would not connect to the experience machine, many would not (...) disconnect from it either if they were already connected. Unless we have a reason to privilege the views of those currently disconnected, Nozick fails to prove his broader point about the nature of value. This article was published when I was an undergraduate. I am posting it now to SSRN because the topic has gained renewed interest among experimental philosophers and neuroethicists. (shrink)

Subjective theories of wellbeing place authority concerning what benefits a person with that person herself, or limit wellbeing to psychological states. But how well off we are seems to depend on two different concerns, how well we are doing and how well things are going for us. I argue that two powerful subjective theories fail to adequately account for this and that principled arguments favoring subjectivism are unsound and poorly motivated. In the absence of more compelling evidence that how things (...) go for us cannot directly constitute our wellbeing, I conclude that wellbeing is objective. (shrink)

Nozick’s Experience Machine thought experiment is generally taken to make a compelling, if not conclusive, case against philosophical hedonism. I argue that it does not and, indeed, that regardless of the results, it cannot provide any reason to accept or reject either hedonism or any other philosophical account of wellbeing since it presupposes preferentism, the desire-satisfaction account ofwellbeing. Preferentists cannot take any comfort from the results of such thought experiments because they assume preferentism and therefore cannot establish it. Neither can (...) anyone else, since only a preferentist should accept the terms of the thought experiment. (shrink)
