I see two main views of learning. The first is like stamp collecting. The person wants to collect more and more knowledge, mostly for the purposes of showing it off to people they want to impress. The knowledge here is largely inert and unimportant for their lives—it’s just a collecting hobby accruing more facts and ideas.
There’s nothing wrong with stamp collecting. Knowing facts and ideas, even if they aren’t particularly useful or central to our lives, isn’t a bad thing. It’s probably a superior hobby to many other pursuits, since knowledge can, at least some of the time, spillover to more practical consequences.
The other view of learning, however, is centered around unlearning. This is the view that what we think we know about the world is a veneer of sense-making atop a much deeper strangeness. The things we think we know, we often don’t. The ideas, philosophies and truths that guide our lives may be convenient approximations, but often the more accurate picture is a lot stranger and more interesting.
