The sixth element that enabled the West to dominate the rest was the work ethic. Max Weber famously linked it to Protestantism, but the reality is that any culture, regardless of religion, is capable of embracing the spirit of capitalism by working hard, saving, and accumulating capital.
The question is why that ethic seems now to be fading in the West. Europeans no longer work long hours, and Americans have almost given up saving completely. The real workers and savers in the world are now the heirs of Confucius, not Calvin.
Perhaps, ironically, the biggest threat to Western civilization could turn out to be this Westernization of the world, if the consequence of Asian economic growth is to change the global climate for the worse.
Yet these fears may underestimate the ability of Western civilization to solve the world's problems.
In the final programme of the series, Niall Ferguson argues that the real threat to our survival is our loss of faith not in religion but in ourselves.
