That all pleasure is good and all pain bad in itself is an eternally true ethical principle. The common claim that some pleasure is not good, or some pain not bad, is mistaken. Strict particularism (ethical decisions must be made case by case; there are no sound universal normative principles) and relativism (all good and bad are relative to society) are among the ethical theories we may refute through an appeal to pleasure and pain. Daniel Dennett, Philippa Foot, R M Hare, Gilbert Harman, Immanuel Kant, J. L. Mackie, and Jean-Paul Sartre are among the many philosophers addressed.

Pleasure, in the inclusive usages most important in moral psychology, ethical theory, and the studies of mind, includes all joy and gladness — all our feeling good, or happy. It is often contrasted with similarly inclusive pain, or suffering, which is similarly thought of as including all our feeling bad. Contemporary psychology similarly distinguishes between positive affect and negative affect.[1..

The liking of a sensation, e.g., a taste, is a conscious occurrent but does not consist in having the liked sensation accompanied by a "pleasure sensation" - for there is no such sensation. Several alternative accounts of liking, including Aydede's "feeling episode" theory and Schroeder's representationalist theory are considered. The proposal that liking a sensation is having the non-sensory experience of liking directed upon it is explained and defended. The pleasure provided by thoughts, conversations, walks, etc., is analyzed and brought into relation to the account of liking one's sensations.

Why is pain the opposite of pleasure? Several theories of pleasure and pain have substantial difficulty explaining this basic feature. Theories according to which pleasure and pain are individual sensations or features of sensations have particular difficulty, since it is difficult to understand how pairs of sensations could be opposites. Some philosophers argue that the pain is the opposite of pleasure because pain and pleasure are fundamentally a matter of desire and aversion, and desire and aversion are clear opposites. I argue that the structure of desire and aversion does not correspond to that of pleasure and pain. I propose that pleasure and pain are opposites because pleasure is good and pain is bad, and good and bad are clear opposites. I show that this view explains the structure of opposition of pleasure and pain, and I answer several objections.

Against Hume and Epicurus I argue that our selection of pleasure, pain and other objects as our ultimate ends is guided by reason. There are two parts to the explanation of our attraction to pleasure, our aversion to pain, and our consequent preference of pleasure to pain: 1. Pleasure presents us with reason to seek it, pain presents us reason to avoid it, and 2. Being intelligent, human beings (and to a degree, many animals) are disposed to be guided by reason, and hence by what there is reason to choose, seek, and prefer, when they act.

I take up the issue of whether pleasure is a kind of sensation (a feeling episode) or not. This issue was much discussed by philosophers of the 1950's and 1960's, and no resolution was reached. There were mainly two camps in the discussion: those who argued for a dispositional account of pleasure, and those who favored an episodic feeling (sensational) view of pleasure. Here, relying on some recent scientific findings I offer an account of pleasure which neither dispositionalizes nor sensationalizes pleasure. As is usual in the tradition, I compare pleasure with pain, and try to see its similarities and differences. I argue that pain and pleasure experiences have typically a complex phenomenology normally not so obvious in introspection. After distinguishing between affective and sensory components of these experiences, I argue that although pain experiences normally consist of both components proper to them, pleasure, in contradistinction to pain, is only the affective component of a total experience that may involve many sensations proper and cognitions. Moreover, I hold that although the so-called "physical" pleasure is itself not a sensation proper, it is nevertheless an episodic affective reaction (in a primitive sense) to sensations proper.
