You do get one for this, George.
But this begs for me to trot out some words to live by I came up with several years ago (although if Rich Goodale sees this I'm sure he'll claim them as his own):
Newton tells us how
Shakespeare tell us why.
Oh, the "how" matters, big time. Modern society depends on it.
But the "why" delves so much more into the soul... and is so much more interesting... and timeless.
So by my reckoning, the word geeks are always going to be way ahead.
So why do street creators use round manhole covers? Sure, the simple answer is so that they won't fall through the hole. The fare more interesting answer would delve into the tragic occurrences of man's inhumanity to man, and the darkness of his soul.
