Williams argues that if a person's character changes in the future, their present self may not be attracted to the projects of their future self. Fischer counters that what matters most is the way in which a person's character changes over time. The document concludes by stating that an immortal life does not need to consist solely of pleasurable activities to be attractive, and that the standards for an immortal existence should match those for a regular mortal life, as long as it includes a variety of experiences like pleasures, spiritual activities, and religion spaced appropriately over an infinite time period.

1. Changes of Character
 Williams: If our character changes in the
future, it’s unclear why our present selves
would be attracted to the projects of this
future self
 Fischer: What matters is the way that our
character changes

2. Summing Up
 Immortality need not consist of a single pleasurable activity to be
attractive.
 Immortality need not consist solely of pleasurable activities to be
attractive.
 The standards for immortality should match those for a mortal
existence.
 An immortal life consisting only of self-exhausting pleasures
would be boring—but there’s no reason to think a life of
repeatable pleasures, appropriately spaced (and perhaps
combined with spiritual and religious experiences) could not give
rise to positive categorical desires even in an immortal life.
