It seems to me absolutely true, that our world, which appears to us the surface of all things, is really the bottom of a deep ocean: all our trees are submarine growths, and we are weird, scaly-clad submarine fauna, feeding ourselves on offal like shrimps. Only occasionally the soul rises gasping through the fathomless fathoms under which we live, far up to the surface of the ether, where there is true air.
So those who wished for some central cosmic purpose for us, or at least our world, or at least our solar system, or at least our galaxy, have been disappointed, progressively disappointed. The universe is not responsive to our ambitious expectations.
It should not be Illiers-Combray that we visit: a genuine homage to Proust would be to look at our world through his eyes, not look at his world through our eyes.
