Book excerpt: This collection vigorously addresses the religious implications of extreme human enhancement technology. Topics covered include cutting edge themes, such as moral enhancement, common ground to both transhumanism and religion, the meaning of death, desire and transcendence, and virtue ethics. Radical enhancement programs, advocated by transhumanists, could arguably have a more profound impact than any other development in human history. Reflecting a range of opinion about the desirability of extreme enhancement, leading scholars in the field join with emerging scholars to foster enhanced conversation on these topics.
