Abstract

This chapter discusses the retroactivity problem and how it arises when the idea that events occurring after a person’s life can harm that person is pursued. The common objection to this dilemma is the “no subject” type of response. The retroactivity problem is the result of making several assumptions jointly, many of which are initially plausible but none of which are actually defended. The first of these assumptions is referred to as Worse-Off, which states that an event harms a person only if it makes him worse off than he would have been if the event had not occurred. The second assumption, implied by the first, is referred to as Welfare, which states that an event harms a person only if it makes it the case that his welfare is lower than it would have been if the event had not occurred.
