Upgrading Humanity

It's outdated to think that the essence of our humanity lies in our chromosomes.

Suppose you were offered a photographic memory, perfect pitch, ultraviolet-spectrum vision, heightened disease resistance, customized skin and eye color, and a one-thousand-year life-expectancy. Would you accept? Now suppose you were told that by doing so you would cease to be human. Would this make you less willing to accept? If you're like me, you'll answer "Yes" to the first question and "No" to the second. I could stand the improvements, and if they make me more than "human," so what? If you answer "Yes" to the first question but say that leaving humanness behind would actually make you more willing to accept, you may be a "transhumanist," the new breed of perfectionists who aim at collective self-improvement through direct modification of "human nature." According to Nick Bostrom, a young philosopher at Oxford and a leading transhumanist:

"Transhumanists view human nature as a work-in-progress, a half-baked beginning that we can learn to remold in desirable ways. Current humanity need not be the endpoint of evolution. Transhumanists hope that by responsible use of science, technology, and other rational means we shall eventually manage to become post-human, beings with vastly greater capacities than present human beings have.1 Whereas humanists for centuries have settled for trying to perfect humanity, transhumanists want to transcend it. "Transhumanism has roots in secular humanist thinking, yet is more radical in that it promotes not only traditional means of improving human nature, such as education and cultural refinement, but also direct application of medicine and technology to overcome some of our basic biological limits."

Every day, real scientific breakthroughs suggest that transhumanist hopes are no longer merely the stuff of William Gibson's science-fiction novel "Neuromancer." Life spans of laboratory mice have been doubled; transgenic animals are commonplace; jellyfish genes have been inserted into the hair follicles of mice to make them glow; a network of snail brain cells has been connected to a silicon chip, perhaps speeding the day when microchip implants can control artificial limbs, restore sight, and revive memory. Highly prominent cultural commentators like bioethicist Leon Kass, political scientist Francis Fukuyama, environmentalist Bill McKibben, and even Sun Microsystems cofounder Bill Joy have begun calling for caution, or even preemptive prohibition of human "germ-line" genetic engineering (transhumanists label such attitudes "bioconservatism"). An increasingly public debate over our "posthuman future" has ensued. Unfortunately, it has often lacked the clarity of computer-mediated vision.
