"“Scientists may eventually be able to extend some people’s lives for many hundreds or even thousands of years. This book is a friendly argument between two eminent philosophers about whether this would be good or bad for those people. Even if none of us now will be fortunate (or unfortunate) enough to be around to experience radical life extension, we can still benefit enormously from this debate’s illuminating exchanges, conducted with wit and verve, about death, the meaning and value of life, the nature of well-being, the metaphysics of personal identity, and many other fascinating and fundamentally important topics.” -- Jeff McMahan, University of Oxford ""This book will reward anyone interested in the question of whether there's reason to live forever. And let's be honest, that's all of us. Cave and Fischer offer up a timely debate on a timeless issue."" -- Benjamin Mitchell-Yellin, Sam Houston State University"
