I was just thinking about this post and I remembered this old documentary from Patrick Moore, former president of the British Astronomy Association. It's remarkable that any television company of the time would produce something like this. The premise is pretty simple, Moore goes around talking to people with ideas that are very out of the ordinary. He says he disagrees with most of them, but he is willing to hear them out, and even praises them for having the courage to think outside the box.

After seeing the documentary, I wrote this article, A Free Marketplace of Ideas, about how, in a society which doesn't have a centralised system of education, we should expect that people have wildly different ideas about what the world is and how it works.
