Pleasure

Pleasure is experience that feels good, that involves the enjoyment of something. It contrasts with pain or suffering, which are forms of feeling bad. It is closely related to value, desire and action: humans and other conscious animals find pleasure enjoyable, positive or worthy of seeking. A great variety of activities may be experienced as pleasurable, like eating, having sex, listening to music or playing games. Pleasure is part of various other mental states such as ecstasy, euphoria and flow. Happiness and well-being are closely related to pleasure but not identical with it. There is no general agreement as to whether pleasure should be understood as a sensation, a quality of experiences, an attitude to experiences or otherwise. Pleasure plays a central role in the family of philosophical theories known as hedonism.

Definition

"Pleasure" refers to experience that feels good, that involves the enjoyment of something. The term is primarily used in association with sensory pleasures like the enjoyment of sex or food. But in its most general sense, it includes all types of positive or pleasant experiences including the enjoyment of sports, seeing a beautiful sunset or engaging in an intellectually satisfying activity.
Pleasure contrasts with pain or suffering, which are forms of feeling bad. Both pleasure and pain come in degrees and have been thought of as a dimension going from positive degrees through a neutral point to negative degrees. This assumption is important for the possibility of comparing and aggregating the degrees of pleasure of different experiences, for example, in order to perform the Utilitarian calculus.

Related concepts

The concept of pleasure is similar but not identical to the concepts of well-being and of happiness. These terms are used in overlapping ways, but their meanings tend to come apart in technical contexts like philosophy or psychology. Pleasure refers to a certain type of experience while well-being is about what is good for a person. Many philosophers agree that pleasure is good for a person and therefore is a form of well-being. But there may be other things besides or instead of pleasure that constitute well-being, like health, virtue, knowledge or the fulfillment of desires. On some conceptions, happiness is identified with "the individual's balance of pleasant over unpleasant experience". Life satisfaction theories, on the other hand, hold that happiness involves having the right attitude towards one's life as a whole. Pleasure may have a role to play in this attitude, but it is not identical to happiness.
Pleasure is closely related to value, desire, motivation and right action. There is broad agreement that pleasure is valuable in some sense.

Types

Pleasure is sometimes subdivided into fundamental pleasures that are closely related to survival and higher-order pleasures.
Jeremy Bentham listed 14 kinds of pleasure; sense, wealth, skill, amity, a good name, power, piety, benevolence, malevolence, memory, imagination, expectation, pleasures dependent on association, and the pleasures of relief.
Some commentators see 'complex pleasures' including wit and sudden realisation, and some see a wide range of pleasurable feelings.
Nick Bostrom listed 3 types of pleasure;

pleasant or voluptuous bodily sensations.
thrills from high-energy socialising, consumerism, and indulgence.
positive hedonic tone, meaning an unmediated liking of the ways things present in the moment.
Theories of pleasure

Theories of pleasure try to determine what pleasurable experiences have in common, what is essential to them. They are traditionally divided into

quality theories; that pleasure is a quality of pleasurable experiences themselves,
attitude theories; that pleasure is in some sense external to the experience since it depends on the subject's attitude to the experience. An alternative terminology refers to these theories as phenomenalism and intentionalism.
hybrid or dispositional theories, that incorporate elements of both quality and attitude approaches.
Quality theories

In everyday language, the term "pleasure" is primarily associated with sensory pleasures like the enjoyment of food or sex. One traditionally important quality-theory closely follows this association by holding that pleasure is a sensation. On the simplest version of the sensation theory, whenever we experience pleasure there is a distinctive pleasure-sensation present. So a pleasurable experience of eating chocolate involves a sensation of the taste of chocolate together with a pleasure-sensation. An obvious shortcoming of this theory is that many impressions may be present at the same time. For example, there may be an itching sensation as well while eating the chocolate. But this account cannot explain why the enjoyment is linked to the taste of the chocolate and not to the itch. Another problem is due to the fact that sensations are usually thought of as localized somewhere in the body. But considering the pleasure of seeing a beautiful sunset, there seems to be no specific region in the body at which we experience this pleasure.
These problems can be avoided by felt-quality-theories, which see pleasure not as a sensation but as an aspect qualifying sensations or other mental phenomena. As an aspect, pleasure is dependent on the mental phenomenon it qualifies, it cannot be present on its own. Since the link to the enjoyed phenomenon is already built into the pleasure, it solves the problem faced by sensation theories to explain how this link comes about. It also captures the intuition that pleasure is usually pleasure of something: enjoyment of drinking a milkshake or of playing chess but not just pure or object-less enjoyment. According to this approach, pleasurable experiences differ in content but agree in feeling or hedonic tone. Pleasure can be localized, but only to the extent that the impression it qualifies is localized.
One objection to both the sensation theory and the felt-quality theory is that there is no one quality shared by all pleasure-experiences. The force of this objection comes from the intuition that the variety of pleasure-experiences is just too wide to point out one quality shared by all, for example, the quality shared by enjoying a milkshake and enjoying a chess game. One way for quality theorists to respond to this objection is by pointing out that the hedonic tone of pleasure-experiences is not a regular quality but a higher-order quality. As an analogy, a vividly green thing and a vividly red thing do not share a regular color property but they share "vividness" as a higher-order property.

Attitude theories

Attitude theories propose to analyze pleasure in terms of attitudes to experiences. So to enjoy the taste of chocolate it is not sufficient to have the corresponding experience of the taste. Instead, the subject has to have the right attitude to this taste for pleasure to arise. This approach captures the intuition that a second person may have exactly the same taste-experience but not enjoy it since the relevant attitude is lacking. Various attitudes have been proposed for the type of attitude responsible for pleasure, but historically the most influential version assigns this role to desires. On this account, pleasure is linked to experiences that fulfill a desire had by the experiencer. So the difference between the first and the second person in the example above is that only the first person has a corresponding desire directed at the taste of chocolate.
One important argument against this version is that while it is often the case that we desire something first and then enjoy it, this cannot always be the case. In fact, often the opposite seems to be true: we have to learn first that something is enjoyable before we start to desire it. This objection can be partially avoided by holding that it does not matter whether the desire was there before the experience but that it only matters what we desire while the experience is happening. This variant, originally held by Henry Sidgwick, has recently been defended by Chris Heathwood, who holds that an experience is pleasurable if the subject of the experience wants the experience to occur for its own sake while it is occurring. But this version faces a related problem akin to the Euthyphro dilemma: it seems that we usually desire things because they are enjoyable, not the other way round. So desire theories would be mistaken about the direction of explanation. Another argument against desire theories is that desire and pleasure can come apart: we can have a desire for things that are not enjoyable and we can enjoy things without desiring to do so.

Dispositional theories

Dispositional theories try to account for pleasure in terms of dispositions, often by including insights from both the quality theories and the attitude theories. One way to combine these elements is to hold that pleasure consists in being disposed to desire an experience in virtue of the qualities of this experience. Some of the problems of the regular desire theory can be avoided this way since the disposition does not need to be realized for there to be pleasure, thereby taking into account that desire and pleasure can come apart.

Roles in philosophy

Hedonism

Pleasure plays a central role in theories from various areas of philosophy. Such theories are usually grouped together under the label "hedonism". Axiological hedonists hold that pleasure is the only thing that has intrinsic value. Many desires are concerned with pleasure. Psychological hedonism is the thesis that all our actions aim at increasing pleasure and avoiding pain. Freud's pleasure principle ties pleasure to motivation and action by holding that there is a strong psychological tendency to seek pleasure and to avoid pain. Classical utilitarianism connects pleasure to ethics in stating that whether an action is right depends on the pleasure it produces: it should maximize the sum-total of pleasure.
