Many thanks Steve. All very interesting, and I am certainly better informed now than at the start of this thread.
I am reminded of Dr Samuel Johnson’s response to Bishop Berkeley’s claim that everything is an idea without material substance – Johnson kicked a large stone, saying “I refute it thus!” On a pragmatic level, so long as I can continue to see the light, that will do for me!
Merry Christmas
