Summary of Nick Bostrom’s,  “The Fable of the Dragon-Tyrant”

Nick Bostrom (1973 – ) holds a PhD from the London School of Economics (2000). He is a co-founder of the World Transhumanist Association (now called Humanity+) and co–founder of the Institute for Ethics and Emerging Technologies. He was on the faculty of Yale University until 2005, when he was appointed Director of the newly created Future of Humanity Institute at Oxford University. He is currently Professor, Faculty of Philosophy & Oxford Martin School; Director, Future of Humanity Institute; and Director, Program on the Impacts of Future Technology; all at Oxford University.

Bostrom’s article, “The Fable of the Dragon-Tyrant,” tells the story of a planet ravaged by a dragon (death) that demands a tribute which is satisfied only by consuming thousands of people each day. Neither priests with curses, warriors with weapons, or chemists with concoctions could defeat the dragon. The elders were selected to be sacrificed, although they were often wiser than the young, because they had at least lived longer than the youth. Here is a description of their situation:

Spiritual men sought to comfort those who were afraid of being eaten by the dragon (which included almost everyone, although many denied it in public) by promising another life after death, a life that would be free from the dragon-scourge. Other orators argued that the dragon has its place in the natural order and a moral right to be fed. They said that it was part of the very meaning of being human to end up in the dragon’s stomach. Others still maintained that the dragon was good for the human species because it kept the population size down. To what extent these arguments convinced the worried souls is not known. Most people tried to cope by not thinking about the grim end that awaited them.[i]

Given the ceaselessness of the dragon’s consumption, most people did not fight it and accepted the inevitable. A whole industry grew up to study and delay the process of being eaten by the dragon, and a large portion of the society’s wealth was used for these purposes. As their technology grew, some suggested that they would one day build flying machines, communicate over great distances without wires, or even be able to slay the dragon. Most dismissed these ideas.

Finally, a group of iconoclastic scientists figured out that a projectile could be built to pierce the dragon’s scales. However, to build this technology would cost vast sums of money and they would need the king’s support. (Unfortunately, the king was busy raging war killing tigers, which cost the society vast sums of wealth and accomplished little.) The scientists then began to educate the public about their proposals and the people became excited about the prospect of killing the dragon. In response the king convened a conference to discuss the options.

First to speak was a scientist who explained carefully how research should yield a solution to the problem of killing the dragon in about twenty years. But the king’s moral advisors said that it is presumptuous to think you have a right not to be eaten by the dragon; they said that finitude is a blessing and removing it would remove human dignity and debase life. Nature decries, they said, that dragons eat people and people should be eaten. Next to speak was a spiritual sage who told the people not to be afraid of the dragon, but a little boy crying about his grandma’s death moved most toward the anti-dragon position.

However, when the people realized that millions would die before the research was completed, they frantically sought out financing for anti-dragon research and the king complied. This started a technological race to kill the dragon, although the process was painstakingly slow, and filled with many mishaps. Finally, after twelve years of research the king launch a successful dragon-killing missile. The people were happy but the king saddened that they had not started their research years earlier—millions had died unnecessarily. As to what was next for his civilization, the king proclaimed: “Today we are like children again. The future lies open before us. We shall go into this future and try to do better than we have done in the past. We have time now—time to get things right, time to grow up, time to learn from our mistakes, time for the slow process of building a better world…”[ii] 

Summary – We should try to overcome the tyranny of death with technology.

  1. If you put it in the form of a fable, fighting to cure ageing and death really sound so obvious. I love it.

    And thank you so much for all the hard work that you put into your blog. i am an avid reader and it really is a great source of inspiration to me.
