He does speculate that on God's part, one reason why He may withhold some info from us is that He is sparing us from things we can't handle.
But on our part, Pope mentions only two cases where the pursuit of info could be sinful. First, details about people’s private lives, which are none of our business. That would be violation of privacy. Second, info by which we can acquire destructive power over others.
Other than that, as I read it, Pope is saying that pursuit of some secret knowledge might lead to grief, may often be useless, but without necessarily being sinful.
That makes sense. Thank you.
Could an example be “Knowing why someone died”?
