Culture tends to argue that it forbids only that which is unnatural. But from a biological perspective, nothing is unnatural. Whatever is possible is… - Yuval Noah Harari

Whatever is possible is by definition also natural.

Not only rationality, but individuality too is a myth. Humans rarely think for themselves. Rather, we think in groups. Just as it takes a tribe to raise a child, it also takes a tribe to invent a tool, solve a conflict, or cure a disease. No individual knows everything it takes to build a cathedral, an atom bomb, or an aircraft. What gave Homo sapiens an edge over all other animals and turned us into the masters of the planet was not our individual rationality but our unparalleled ability to think together in large groups.1

In a world deluged by irrelevant information, clarity is power.

So if you blame Facebook, Trump, or Putin for ushering in a new and frightening era of post-truth, remind yourself that centuries ago millions of Christians locked themselves inside a self-reinforcing mythological bubble, never daring to question the factual veracity of the Bible, while millions of Muslims put their unquestioning faith in the Quran. For millennia, much of what passed for “news” and “facts” in human social networks were stories about miracles, angels, demons, and witches, with bold reporters giving live coverage straight from the deepest pits of the underworld. We have zero scientific evidence that Eve was tempted by the serpent, that the souls of all infidels burn in hell after they die, or that the creator of the universe doesn’t like it when a Brahmin marries a Dalit — yet billions of people have believed in these stories for thousands of years. Some fake news lasts forever.
