Book excerpt: N this volume, Feinberg focuses on the meanings of "interest," the relationship between interests and wants, and the distinction between want-regarding and ideal-regarding analyses on interest and hard cases for the applications of the concept of harm. Examples of the "hard cases" are harm to character, vicarious harm, and prenatal and posthumous harm. Feinberg also discusses the relationship between harm and rights, the concept of a victim, and the distinctions of various quantitative dimensions of harm, consent, and offense, including the magnitude, probability, risk, and "importance" of harm.
