Uh, why would Carl Sagan say anything about being moved at a spiritual level, and then say something that indicates the spiritual level doesn't exist? Seems a bit of a contradiction.
Did you see the series “Cosmos”? All of these were from Carl Sagan. Frankly, if you read these three, which doesn’t belong?
“The cosmos is all that is or ever was or ever will be.”
“It is very hard to look at the beauty, intricacy, and subtlety of nature without feeling awe. I don’t think even the word reverence is too strong.”
“Our feeblest contemplations of the Cosmos stir us-there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.”
