But now I see three stages in our life. At first, we bask contented in our sun And take what daylight shows us for the truth. Then we discover, in some midnight grief, How all day long the sunlight blinded us To depths beyond, where all our knowledge dies. That's where men shrink, and lose their way in doubt. Then, last, as death draws nearer, comes a night In whose majestic shadow men see God, Absolute Knowledge, reconciling all. So, all my life I pondered on that scheme Which makes this earth the centre of all worlds, Lighted and wheeled around by sun and moon And that great crystal sphere wherein men thought Myriads of lesser stars were fixed like lamps, Each in its place,--one mighty glittering wheel Revolving round this dark abode of man. Night after night, with even pace they moved. Year after year, not altering by one point, Their order, or their stations, those fixed stars In that revolving firmament. The Plough Still pointed to the Pole. Fixed in their sphere, How else explain that vast unchanging wheel? How, but by thinking all those lesser lights Were huger suns, divided from our earth By so immense a gulf that, if they moved Ten thousand leagues an hour among themselves, It would not seem one hair's-breadth to our eyes. Utterly inconceivable, I know; And yet we daily kneel to boundless Power And build our hope on that Infinitude. This did not daunt me, then. Indeed, I saw Light upon chaos. Many discordant dreams Began to move in lucid music now. For what could be more baffling than the thought That those enormous heavens must circle earth Diurnally--a journey that would need Swiftness to which the lightning flash would seem A white slug creeping on the walls of night; While, if earth softly on her axle spun One quiet revolution answered all. It was our moving selves that made the sky Seem to revolve. Have not all ages seen A like illusion baffling half mankind In life, thought, art? Men think, at every turn Of their own souls, the very heavens have moved.
