In 1989, Francis Fukuyama made his now-famous pronouncement that because “the major alternatives to liberal democracy had exhausted themselves,” history as we knew it had reached its end. Ten years later, he revised his argument: we hadn’t reached the end of history, he wrote, because we hadn’t yet reached the end of science. Arguing that our greatest advances still to come will be in the life sciences, Fukuyama now asks how the ability to modify human behavior will affect liberal democracy.

To re-orient contemporary debate, Fukuyama underlines man’s changing understanding of human nature through history: from Plato and Aristotle’s belief that man had “natural ends,” to the ideals of utopians and dictators of the modern age who sought to remake mankind for ideological ends. Fukuyama persuasively argues that the ultimate prize of the biotechnology revolution-intervention in the “germ-line,” the ability to manipulate the DNA of all of one person’s descendents-will have profound, and potentially terrible, consequences for our political order, even if undertaken by ordinary parents seeking to “improve” their children.

In Our Posthuman Future, our greatest social philosopher begins to describe the potential effects of exploration on the foundation of liberal democracy: the belief that human beings are equal by nature.

Is a baby whose personality has been chosen from a gene supermarket still a human? If we choose what we create what happens to morality? Is this the end of human nature? The dramatic advances in DNA technology over the last few years are the stuff of science fiction. It is now not only possible to clone human beings it is happening. For the first time since the creation of the earth four billion years ago, or the emergence of mankind 10 million years ago, people will be able to choose their children’s’ sex, height, colour, personality traits and intelligence. It will even be possible to create ‘superhumans’ by mixing human genes with those of other animals for extra strength or longevity. But is this desirable? What are the moral and political consequences? Will it mean anything to talk about ‘human nature’ any more? Is this the end of human beings? Our Posthuman Future is a passionate analysis of the greatest political and moral problem ever to face the human race.
