Unpleasant experiences include backaches, moments of nausea, moments of nervousness, phantom pains, and so on. What does their unpleasantness consist in? The unpleasantness of an experience has been thought to consist in: (1) its representing bodily damage; (2) its inclining the subject to fight its continuation; (3) the subject's disliking it; (4) features intrinsic to it. I offer compelling objections to (1) and (2) and less compelling objections to (3). I defend (4) against five challenging objections and offer two reasons to believe it. Hence, I advocate "Intrinsic Nature," the idea that unpleasantness is intrinsic to unpleasant experiences.

Ethicists and economists commonly assume that if A is all things considered better than B, and B is all things considered better than C, then A is all things considered better than C. Call this principle Transitivity. Although it has great conceptual, intuitive, and empirical appeal, I argue against it. Larry S. Temkin explains how three types of ethical principle, which cannot be dismissed a priori, threaten Transitivity: (a) principles implying that in some cases different factors are relevant to comparing A to C than to comparing A to B or B to C; (b) principles of limited scope; (c) principles implying that morally relevant differences in degree can amount to differences in kind. My counterexamples employ a principle of type (c): pleasures and pains enormously different in intensity differ in kind. Temkin has also endorsed this type of counterexample, using arguments based on earlier drafts of this paper.
