Human enhancement is an important topic. However, too many authors dwell on improbable scenarios, such as genetic engineering of super-babies. By contrast, this book tackles the real ethical dilemmas that our society faces today. Is it wrong for healthy college students to boost academic performance with Ritalin and similar drugs? Is increased longevity a bane or a boon? How can simple interventions like good nutrition and vaccinations produce children who are not only healthier but smarter? Professor Gregory Pence uses science, logic, and ethics to analyze these and many other topics. Along the way, he explains why we need not fear designer babies and other Brave New World scenarios. Legislators and other policymakers should read this timely and fascinating book so that they will know what to regulate—and what to leave alone.
