This slim volume is the best introduction to the ethical debate over human cloning now available, as two of America's most respected public intellectuals tangle over the question of whether it's a good idea to let people make genetic duplicates of themselves. Kass is firmly against human cloning; Wilson, although not exactly an enthusiast, sees no essential problem with it as long as cloned children are raised in loving, two-parent households.
The book is divided into two parts, with each writer laying out an initial position followed by mutual critiques. Kass seems to get the better of the exchange, but both writers present their views clearly, with occasional humor. (Wilson at one point shrugs off the concern that cloning will replace sexual reproduction: "Sex is more fun than cloning.... Procreation is a delight.") This outstanding book will shape a debate that's only just gotten underway. --John J. Miller
This accessible volume promises to inform the public policy debate over the permissible conduct of genetic research and the permissible uses of its discoveries.
