If one could ride a time machine back to the past, no matter which era, one thing would remain unchanged: “Misfortune comes from the mouth.” You must be careful about what you say.
Words that you believe are harmless can bring you great trouble.
Today, saying that the Earth revolves around the Sun is utterly commonplace. However, if this were said in 17th-century Europe, it would lead to great disaster.
Galileo said these words, and as a result, he faced judgment by the religious court.
Nerds are the ones who get into trouble like that.
They wear unpopular clothes and speak inappropriate words.
They feel they have expressed the correct viewpoint, but in reality, they bring about trouble.
The power of custom is insufficient to restrain them.
The norm of history seems to be that people of any era will deeply believe in certain absurdities.
Their beliefs are also very firm; as long as someone shows even a slight doubt, it will bring great trouble. Is our era any different? As long as you have read a little history, you know the answer is almost certainly and definitively: “No difference.”
Even if there is that tiny possibility—for the first time in history—that all the beliefs of our era are correct, that would be due to astonishing coincidence, not because we have truly found the correct direction.
Just thinking about the things we assert with absolute conviction now, which in the eyes of future people are absurd, how can one not be amazed!
