Immortal Passage: Philosophical Speculations on Posthuman Evolution defends the posthuman hypothesis: that descendants of present humans, leading lives of indefinitely extended duration, and having significantly altered biological, psychological, and social characteristics, will have lives superior to those of current humans. A detailed speculative account of these lives, with attention to philosophical issues raised by such an account, presents the major philosophical challenge of Immortal Passage.
