"At the outset of Life, Liberty and the Defense of Dignity, Leon Kass gives us a status report on where we stand today: "Human nature itself lies on the operating table, ready for alteration, for eugenic and psychic 'enhancement,' for wholesale redesign. In leading laboratories, academic and industrial, new creators are confidently amassing their powers and quietly honing their skills, while on the street their evangelists are zealously prophesying a posthuman future.

For anyone who cares about preserving our humanity, the time has come for paying attention."".

"Trained as a medical doctor and a biochemist, Dr. Kass has become one of our most provocative thinkers on bioethical issues. Now, in this brave and searching book, he also establishes himself as a prophetic voice summoning us to think deeply about the new biomedical technologies threatening to take us back to the future envisioned by Aldous Huxley in Brave New World.

As in Huxley's dystopia, where life has been smoothed out by genetic manipulation, psychoactive drugs and high-tech amusement, our own accelerating efforts to master reproduction and genetic endowment, to retard aging, and to conquer illness, imperfection and even death are animated by our most humane and progressive aspirations.

But we are walking too quickly down the road to physical and psychological utopia, Kass believes, without pausing to assess the potential damage to our humanity from this brave new biology."--BOOK JACKET.
