“We are inveterate poets. When a quantity is very great we cease to regard it as a mere quantity. Our imaginations awake. Instead of mere quantity, we now have a quality—the Sublime. But for this, the merely arithmetical greatness of the Galaxy would be no more impressive than the figures in an account book. To a mind which did not share our emotions and lacked our imaginative energies, the argument against Christianity from the size of the universe would be simply unintelligible. It is therefore from ourselves that the material universe derives its power to overawe us. Men of sensibility look up on the night sky with awe: brutal and stupid men do not. When the silence of the eternal spaces terrified Pascal, it was Pascal’s own greatness that enabled them to do so; to be frightened by the bigness of the nebulae is, almost literally, to be frightened at our own shadow. For light years and geological periods are mere arithmetic until the shadow of man, the poet, the maker of myths, falls upon them. As a Christian I do not say we are wrong to tremble at that shadow, for I believe it to be the shadow of an image of God. But if the Vastness of Nature ever threatens to overcrow our spirits, we must remember that it is only Nature spiritualised by human imagination which does so.”
