But countless crowds in countless manners urged,
From time eternal, by intrinsic weight
And ceaseless repercussion, to combine
In all the possibilities of forms,
Of actions, and connections, and exert
In every change some effort to create--
Reared the rude frame at length, abruptly reared,
Which, when once gendered, must the basis prove
Of things sublime; and whence eventual rose
Heaven, earth, and ocean, and the tribes of sense.
