Why has not Man a microscopic eye? For this plain reason, Man is not a Fly. Say what the use, were finer optics giv'n, T' inspect a mite, not comprehend the heav'n.
Trade it may help, society extend,
But lures the Pirate, ant corrupts the friend:
It raises armies in a nation's aid,
But bribes a senate, and the land's betray'd.
So man, who here seems principal alone, Perhaps acts second to some sphere unknown Touches some wheel, or verges to some goal; 'Tis but a part we see, and not a whole.
Vast chain of being! which from God began, Natures ethereal, human, angel, man, Beast, bird, fish, insect, what no eye can see, No glass can reach, from infinite to Thee, From Thee to nothing.
[T]hro this Air, this Ocean, and this Earth, All Nature quick, and bursting into birth. Above, how high progressive life may go? Around how wide? how deep extend below? Vast Chain of Being! which from God began, Ethereal Essence, Spirit, Substance, Man, Beast, Bird, Fish, Insect! what no Eye can see, No Glass can reach! from Infinite to Thee! From Thee to Nothing.... From Natures Chain whatever Link you strike, Tenth, or ten thousandth, breaks the chain alike.... All are but parts of one stupendous Whole: Whose Body Nature is, and God the Soul.
