Unlike many books about the afterlife, Life after Death makes no appeal to religious faith, divine revelation, or sacred texts. Drawing on some of the most powerful theories and trends in physics, evolutionary biology, science, philosophy, and psychology, D'Souza shows why the atheist critique of immortality is irrational. It is not only reasonable to believe in life after death; it is also beneficial. Such a belief gives depth and significance to this life, a path to happiness, and reason for hope.
