It would be better, perhapsif lecturers actually operated according to those principles. I go to a lecture to get somthing closer to wisdom, indeed. Of it's very hard to get wisdom without information. You need your ma your multiplication tables. You need some historical facts. Ah, you can't just theorize about history without understanding some really tedious factual things at the same time. Factual things alone are not knowledge, they're just facts.
Software Engineer Andy Matuschak talks about his essay "Why Books Don't Work" with EconTalk host Russ Roberts. Matuschak argues that most books rely on transmissionism, the idea that an author can share an idea in print and the reader will absorb it. And yet after reading a non-fiction book, most readers will struggle to remember any of the ideas in the book. Matuschak argues for a different approach to transmitting ideas via the web including different ways that authors or teachers can test for understanding that will increase the chances of retention and mastery of complex ideas.
