Imagine

Once the human mind arrived upon the scene, heaven and earth shrank to make room for imagination.

Starry Night

I've always viewed Starry Night with joy and excitement, never as disturbing or terrifying, for the painting combines the night sky out there with the night sky in here (mind). The feelings of excitement of say a Hubble photograph sometime cannot be seen in the photograph alone (one often adds words and statistics to create the excitement, of course an image in hand of countless galaxies as tiny swirls needs the added knowledge that in fact these tiny swirls are say, 100,000 light years across in diameter, or 587,862,537,318,360,800 mile across). So I think that is when artists are at their best, when they can take that excitement that dwells in the mind and add it to the images on the canvas, and so van Gogh's night sky swirls with excitement -- without a fact or statistic needed.

Addendum
I also see the 'dualing' images 'pointing' to the heavens, the 'natural' cypress and the 'symbolic' church steeple, and too, some speculate this connection to Joseph in Genesis 37:9

"And he dreamed yet another dream, and told it his brethren, and said, Behold, I have dreamed a dream more; and, behold, the sun and the moon and the eleven stars made obeisance to me."

Sometimes

Sometimes I know what I know and other times I know what I don't know and frequently I don't know what I know and more often than not I don't know what I don't know.
