It seems to be a constant throughout history: In every period, people believed things that were just ridiculous, and believed them so strongly that you would have gotten in terrible trouble for saying otherwise.

Is our time any different? To anyone who has read any amount of history, the answer is almost certainly no. It would be a remarkable coincidence if ours were the first era to get everything just right.

How can we find a general recipe for discovering things that are true that you can’t say?

Why look for these things that are true that we can’t say? Curiosity, truth, it’s good for the brain, and because great work tends to grow out of ideas that others have overlooked.

When you find something you can’t say, make sure you pick your battles. Don’t argue with stupid people. But if you have smart and trustworthy friends, it’s good to discuss it with them.
