Stephen,
Your joy and excitement that wasn't yelled out in the caves far below our feet, now is released and expressed! These ideas have cooked, matured and annealed over all these years but have not lost their original sparkle and wonder.
I like the description of reactions to the scenes that don't appear to use thought, but seem reflex. Yes, it's very quick but still the scene has been processed in comparison to wired circuits of all the shapes and patterns you have ever seen, all the experiences you have gone through and even some that are written in your genes.
So reactions to fire and threats like wild animals are reflex derived from our nature but all the other references are built in so efficiently that reaction is close to instant too. Most of our thinking is not accessible to us or we'd get sensory overload. It's processed and filtered in the background every second of the day.
Still there is a big lesson your work teaches, that of walking past treasures within our reach!
Your pictures enrich us. I just hope it does not lead to spoiling the caves!
