See, through this air, this ocean, and this earth,
All matter 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,
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!—On superior pow'rs
Were we to press, inferior might on ours:
Or in the full creation leave a void,
Where, one step broken, the great scale's destroy'd:
From nature's chain whatever link you strike,
Tenth or ten thousandth, breaks the chain alike.

And, if each system in gradation roll
Alike essential to th' amazing whole,
The least confusion but in one, not all
That system only, but the whole must fall.
Let earth unbalanc'd from her orbit fly,
Planets and suns run lawless through the sky;
Let ruling angels from their spheres be hurl'd,
Being on being wreck'd, and world on world;
Heav'n's whole foundations to their centre nod,
And nature tremble to the throne of God.
All this dread order break—for whom? for thee?
Vile worm!—Oh madness, pride, impiety!
