As a truth seeker, I bristle at the idea that there is any knowledge that’s dangerous to have. But there is.
Not in an absolute sense. I don’t believe there’s any knowledge that is always and forever dangerous. But I think almost all knowledge can be dangerous at the wrong time.
It’s easiest to see with children. There are plenty of facts and types of know-how that can damage a child if conveyed too early. No one would deny this.
It’s also hard to deny that all grown humans are still at various stages of maturity, always with room for more. Humanity as a whole is also very young in many ways.
Putting these things together, it logically follows that there is always knowledge that is dangerous to individuals and humanity as a whole.
Does this mean shadowy agencies and secret societies should censor and hide it, cloak and dagger style? No.
Really the only implications worth considering are personal. Recognizing that, on the individual level, there may be knowledge that does not help you but harms you if you are not yet ready for it can help you slow down a little. And remembering the same about others can take the edge off the urge to proselytize.
