I submit that the topics you feel you can't learn, you only think that way because you don't have the proper insights. If someone could have given those to you, then you'd be able to understand them. And if someone truly understood those topics, then they could give you the proper insights. So either insight itself is broken, in that there are certain topics which are immune to it, in that you or anyone could never learn them given the right teacher and the right setting and the right approach, or, well, that's the only option really. The power of insight fails because some minds are patently immune to it.
