We are, I wasn't intending to rebut you, but instead to expand on a a specific aspect you touched upon and tie it back to the context of the discussion in a slightly different way.

I very much agree. In fact, I think discovering new mental models is one of the best ways to come to new understandings about things. My entire stance on topics has changed in the past when I found on revisiting it I now had a mental model that I thought applied better/more closely than the ones available previously, and looking at the topic from that new perspective yielded a different opinion.
My entire stance on topics has changed in the past...
I keep seeing this, revisiting topics, questions, books, etc., and immediately seeing some now-obvious relationship or aspect. It's an argument for returning, at least occasionally, to familiar ground. Though it generally helps to have journeyed elsewhere.
Also for both extensive and intensive reading. Domains which focus exclusively, or even only extensively, on intensive analysis and exploration, seem more prone to going off the rails or ending up at dead ends.
