We are inveterate poets. Our imaginations awake. Instead of mere quantity, we now have a quality—the sublime. Unless this were so, the merely arithmetical greatness of the galaxy would be no more impressive than the figures in a telephone directory. It is thus, in a sense, from ourselves that the material universe derives its power to over-awe us. To a mind which did not share our emotions, and lacked our imaginative energies, the argument from size would be sheerly meaningless. Men look on the starry heavens with reverence: monkeys do not.
