Abstract
This chapter provides comments on some current longevity research. The ultimate aim of longevity research is to stop the aging process, so that none of us need die of old age. The chapter indicates the attitudes towards death and science. It discusses some worries about immortality raised by Leon Kass and Bernard Williams. In “Mortality and Morality: The Virtues of Finitude,” Leon Kass, raised many deep worries about immortality. One was that many of our greatest creations resulted from the recognition of our own mortality. Bernard Williams notes that if our lives persisted unendingly through time, then there would either be significant alterations in a person's deepest projects, commitments, and character, or there would not. The author suggests that we should favor living well over living longer, and ongoing reproduction over immortality, and we should think long and hard before proceeding with certain lines of longevity research.
