Many years ago in one of my university courses, the professor prefaced his presentation of an essay with, “I am a retailer of knowledge. This writer is a primary producer of knowledge.”
I am not certain, but I think it was an essay by the political economist Joseph Schumpter. By about the sixth read through, I had tamed the piece to a 'difficult read'. Before that it was mostly opaque, with ideas I hadn't encountered and words I hadn't seen used in that context.
