The Beginning of Infinity

David Deutsch‘s newest book, The Beginning of Infinity is a tour de force argument for the power of science to transform the world. Deutsch’s main point is that human intelligence, once it reached the point where it started to be used to construct predictive explanations about the behavior of nature, became universal. Here, “universal” means that is can be used to understand any phenomenon and that this understanding leads to the creation of new technologies, which will be used to spread human intelligence throughout the known universe.

The Beginning of Infinity is not just one more book about science and how science is transforming our world. It is an all-encompassing analysis of the way human intelligence and human societies can develop or stagnate, by adopting or refusing to adopt the stance of looking for understandable explanations. Deutsch calls “static” those societies that refuse to look for new, non-supernatural explanations and “dynamic” those that are constantly looking for new explanations, based on objective and checkable evidence. Dynamic societies, he argues, develop and propagate rational memes, while static societies hold on to non-rational memes.

In the process, Deutsch talks authoritatively about evolution, the universality of computation, quantum mechanics, the multiverse and the paradoxes of infinity. They are not disparate subjects since they all become part of one single story on how humanity managed to understand and control the physical world.

Deutsch is at his best when arguing that science and technology are not only positive forces but that they are the only way to ensure the survival of Humanity in the long run. He argues, convincingly, against the myth of Gaia, the idea that the planet is a living being providing us with a generous and forgiving environment as well as against the related, almost universal, concern that technological developments are destroying the planet. This is nonsense, he argues. The future survival of Humanity and the hope of spreading human intelligence throughout the Cosmos reside entirely in our ability to control nature and to bend it to our will. Otherwise, we will follow the path of the many species that became extinct, for not being able to control the natural or unnatural phenomena that led to their extinction.

Definitely, the book to read if you care about the Future of Humanity.


Crystal Nights

Exactly 80 years ago, Kristallnacht (the night of the crystals) took place in Germany, in the night from the 9th to the 10th of November. Jews were persecuted and killed, and their property was destroyed, in an event that is an important marker in the rise of the anti-semitism movement that characterized Nazi Germany. The name comes from the many windows of Jewish-owned stores broken during that night.

Greg Egan, one of my favorite science fiction writers, wrote a short story inspired in that same night, entitled Crystal Nights. This (very) short story is publicly available (you can find it here ) and is definitely worth reading. I will not spoil the ending here, but it has to do with computers and singularities. The story was also included in a book that features other short stories by Greg Egan.

If you like this story, maybe you should check other books by Egan, such as Permutation City, Diaspora or Axiomatic (another collection of short stories).
