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.

What makes it the case that a given experience is pleasurable? According to the felt-quality theory, each pleasurable experience is pleasurable because of the way that it feels—its “qualitative character” or “felt-quality”. According to the attitudinal theory, each pleasurable experience is pleasurable because the experiencer takes certain attitudes towards it. These two theories of pleasure are typically framed as rivals, but it could be that they are both partly right. It could be that pleasure is partly a matter of felt-quality, (...) and partly a matter of attitudes. It could be that a hybrid theory is true. In this paper, I aim to advance the cause of hybrid theories of pleasure. I do this in two ways. I begin by examining the challenges which motivate the search for a hybrid theory. I call these the HONEST challenges: Heterogeneity, Oppositeness, Normativity, Euthyphro, Separateness, and Togetherness. The first three challenges—HON—are challenges for the felt-quality theory. The second three challenges—EST—are challenges for the attitudinal theory. Having established the HONEST challenges, I then describe and motivate a particular cluster of hybrid theories which I will call dispositional hybrid theories. According to these theories, pleasurable experiences are all and only those experiences which dispose us to desire them in virtue of feeling the way that they do. The dispositional theories deliver on the promise of hybrid theories: because they appeal to both felt-qualities and attitudes, they have the resources to avoid most, if not all, of the HONEST challenges.

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)

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)

Theories of welfare answer the ancient question, What makes a person's life go well? Prominent among these are desire-satisfaction or preferentist theories, according to which welfare has to do ultimately with desire. This dissertation aims to criticize some recent popular arguments against standard desire-satisfaction theories of welfare, to develop and defend a novel version of the desire-satisfaction theory capable of answering the better objections, to defend the thesis that pleasure is reducible to desire, and to demonstrate an interesting link between (...) preferentism and hedonism. The second chapter defends a simple "actualist" desire-satisfaction theory against the contention that such a theory cannot accommodate the fact that we can desire things that are bad for us. All the allegedly defective desires, I attempt to show, are either not genuinely defective or else can be accounted for by the theory. The third chapter criticizes the popular line that standard desire-based theories of welfare are incompatible with the conceptual possibility of self-sacrifice. I show that even the simplest imaginable, completely unrestricted desire theory is compatible with self-sacrifice, so long as it is formulated properly. The fourth chapter presents and defends a theory according to which welfare consists in the perceived satisfaction, or "subjective satisfaction," of desire. I argue that this theory is best suited to deflect the many lines of argument threatening the preferentist program. The fifth chapter defends the view that desire is what unifies the heterogeneous lot of experiences that all count as sensory pleasures. I develop and defend a desire theory of sensory pleasure. The sixth chapter argues that the most plausible form of preferentism is equivalent to the most plausible form of its main rival, hedonism. This is because what the best preferentism says---that welfare consists in subjective desire satisfaction---is the same as what the best hedonism says---that welfare consists in propositional pleasure---given a reduction of pleasure to desire along the lines of that defended above.

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)

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.

An encyclopedia entry on hedonistic theories of value and welfare -- the view, roughly, that pleasure is the good.

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.

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.

The paper begins with a well-known objection to the idea that reasons for action are provided by desires. The objection holds that since desires are based on reasons (first premise), which they transmit but to which they cannot add (second premise), they cannot themselves provide reasons for action. In the paper I investigate an attack that has recently been launched against the first premise of the argument by David Sobel. Sobel invokes a counterexample: hedonic desires, i.e. the likings and dislikings (...) of our present conscious states. The aim of the paper is to defend the premise by bringing the alleged counterexample under its scope. I first point out that reference to hedonic desires as a counterexample presupposes a particular understanding of pleasure, which we might call desire-based. In response, following Sobel, I draw up two alternative accounts, the phenomenological and the tracking views of pleasure. Although Sobel raises several objections to both accounts, I argue in detail that the phenomenological view is not as implausible as he claims it to be, whereas the tracking view, on its best version advocated by Thomas Scanlon, is an instance of the phenomenological view and is therefore also defensible.

Most philosophers since Sidgwick have thought that the various forms of pleasure differ so radically that one cannot find a common, distinctive feeling among them. This is known as the heterogeneity problem. To get around this problem, the motivational theory of pleasure suggests that what makes an experience one of pleasure is our reaction to it, not something internal to the experience. I argue that the motivational theory is wrong, and not only wrong, but backwards. The heterogeneity problem is the (...) principal source of motivation for this, otherwise, highly counterintuitive theory. I intend to show that the heterogeneity problem is not a genuine problem and that a more straightforward theory of pleasure is forthcoming. I argue that the various experiences that we call pleasures all feel good. (shrink)

Intrinsic value has traditionally been thought to lie at the heart of ethics. Philosophers use a number of terms to refer to such value. The intrinsic value of something is said to be the value that that thing has “in itself,” or “for its own sake,” or “as such,” or “in its own right.” Extrinsic value is value that is not intrinsic.

One of the leading approaches to the nature of sensory pleasure reduces it to desire: roughly, a sensation qualifies as a sensation of pleasure just in case its subject wants to be feeling it. This approach is, in my view, correct, but it has never been formulated quite right; and it needs to be defended against some compelling arguments. Thus the purpose of this paper is to discover the most defensible formulation of this rough idea, and to defend it against (...) the most interesting objections. (shrink)

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)

A lot of qualitatively very different sensations can be pleasant or unpleasant. The Felt-Quality Views that conceive of sensory affect as having an introspectively available common phenomenology or qualitative character face the “heterogeneity problem” of specifying what that qualitative common phenomenology is. In contrast, according to the Attitudinal Views, what is common to all pleasant or unpleasant sensations is that they are all “wanted” or “unwanted” in a certain sort of way. The commonality is explained not on the basis of (...) phenomenology but by a common mental, usually some sort of conative, attitude toward the sensation. Here I criticize both views and offer an alternative framework that combines what is right in both while avoiding their unintuitive commitments. The result is the reductive (psychofunctionalist) adverbial sensory modification view of pleasure and displeasure. (shrink)

One common answer to the question of the unity of pleasures is to try to define pleasantness by appealing to a kind of mental states whose unity is less questionable. Desires have been conceived as the best candidates for this unifying role. Indeed, one way of classifying the preceding options concerning the definition of pleasantness, is to constrast conative (or motivational) theories of pleasure with non conative ones. Conative theories of pleasure are often considered as one homogeneous type of pleasure (...) reductionism1. But there are indeed two importantly distinct way of defined pleasure with the help of desire: one can define pleasures as objects of desires (D7) or as satisfactions of desires (D8). For convenience, I shall call desirabilist the theory of the first kind (D7) and satisfactionist the theories of the second kind (D8). In the following, I shall argue that both these options fail. On the assumption that D7 and D8 are the only desired-based account of pleasure, this implies that pleasure can’t be reduced to desire. (shrink)

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)
