In Enhancing Evolution, leading bioethicist John Harris dismantles
objections to genetic engineering, stem-cell research, designer babies,
and cloning and makes an ethical case for biotechnology that is both
forthright and rigorous. Human enhancement, Harris argues, is a good
thing--good morally, good for individuals, good as social policy, and
good for a genetic heritage that needs serious improvement. Enhancing
Evolution defends biotechnological interventions that could allow us to
live longer, healthier, and even happier lives by, for example,
providing us with immunity from cancer and HIV/AIDS. Further, Harris
champions the possibility of influencing the very course of evolution to
give us increased mental and physical powers--from reasoning,
concentration, and memory to strength, stamina, and reaction speed.
Indeed, he says, it's not only morally defensible to enhance ourselves;
in some cases, it's morally obligatory.
In a new preface, Harris offers a glimpse at the new science and
technology to come, equipping readers with the knowledge to assess the
ethics and policy dimensions of future forms of human enhancement.
