if you look at 19th century naturalist writing you see descriptions of beautiful rolling valleys and smokestacks, both marked as positive, because the smokestacks are man making his presence felt on a vast an unfeeling wilderness &c.

Oooh, yes, that makes perfect sense given the world frame. The shared worldview (what Barfield would call collective representations) behind the smokestack bellowing smog are so much different from that era to this one!

I will definitely have to pick up Idea of the Holy. It sounds right up my alley. Adding to memories so I don't forget!
