The Most Dangerous Idea on Earth?

It is easy to see how you could be tempted. It might start with genetically screening your children for a lower risk of a hereditary cancer. Or perhaps with a pill that promised to keep your memory fresh and clear into old age.

But what if, while you were having your future children engineered to be cancer-free, you were offered the chance to make them musically gifted? Or, if instead of taking a memory-enhancing pill, you were offered a neural implant that would instantly make you fluent in all the world’s languages? Or cleverer by half? Wouldn’t it be difficult to say no? And what if you were offered a whole new body - one that would never decay or grow old?

A growing number of people believe these will be the fruits of the revolutions in biotechnology expected this century. And they consider it every individual’s right to take advantage of these changes. They think it will soon be within our reach to become something more than human - healthier, stronger, cleverer. All we have to do is live long enough to be around when science makes these advances. If we are, then we may just live forever.

This idea, known as transhumanism, is steadily spreading from a handful of cranks and Star Trek fans into the mainstream and across the Atlantic. But it is an idea that Francis Fukuyama, famed for proclaiming the end of history when US-style liberal democracy triumphed in the cold war, has described as the most dangerous in the world.

In a world at war with terrorism, divided by religious fundamentalism and haunted by racism, sexism and countless other prejudices, how is it that transhumanism has earned the hotly contested title of the most dangerous idea on earth?

According to Nick Bostrom’s “The Transhumanist FAQ”, transhumanists believe “that the human species in its current form does not represent the end of our development but rather a comparatively early phase”. With the help of technology, we will be able to enhance our capacities far beyond their present state. It will be within our reach not only to live longer, but to live better.
