This chapter notes that—especially in the context of personal life—we need to address the question of personal identity before examining arguments from lived experience. The basic claim is that over the course of one’s own life, there is a different person at every point in time—but every new person contains the old versions of myself as proper parts. This is called a “Stack-Theory” of personal identity, drawing inspiration from the “Stage-Theory” by Ted Sider. This “Stack-Theory” has the advantages that there is a very close connection—that of parthood—between me now and my previous versions, and yet, there is still a substantial self present in every moment. Then, this chapter argues that this way of thinking is not as problematic for our personal life as it might initially seem, because—in the words of Ursula K. Le Guin—it is emotionally possible and even positive for us to “work with time instead of against it”. Finally, the role of memory is examined in more detail, and likened to perception in the sense that a true memory is similar to a true perception in that it links us to a really existing thing—in this case, a past moment.
