I. Say first, of God above, or Man below, What can we reason, but from what we know? Of Man, what see we but his station here, From which to reason, or to which refer? 20 Thro' worlds unnumber'd tho' the God be known, 'Tis ours to trace him only in our own. He, who thro' vast immensity can pierce, See worlds on worlds compose one universe, Observe how system into system runs, 25 What other planets circle other suns, What vary'd Being peoples ev'ry star, May tell why Heav'n has made us as we are. But of this frame the bearings, and the ties, The strong connexions, nice dependencies, 30 Gradations just, has thy pervading soul Look'd thro'? or can a part contain the whole? Is the great chain, that draws all to agree, And drawn supports, upheld by God, or thee? II. Presumptuous Man! the reason wouldst thou find, 35 Why form'd so weak, so little, and so blind? First, if thou canst, the harder reason guess, Why form'd no weaker, blinder, and no less? Ask of thy mother earth, why oaks are made Taller or stronger than the weeds they shade? 40 Or ask of yonder argent fields above, Why JOVE'S satellites are less than JOVE? Of Systems possible, if 'tis confest That Wisdom infinite must form the best, Where all must full or not coherent be, 45 And all that rises, rise in due degree; Then, in the scale of reas'ning life, 'tis plain, There must be, somewhere, such a rank as Man: And all the question (wrangle e'er so long) Is only this, if God has plac'd him wrong? 50 Respecting Man, whatever wrong we call, May, must be right, as relative to all. In human works, tho' labour'd on with pain, A thousand movements scarce one purpose gain; In God's, one single can its end produce; 55 Yet serves to second too some other use. 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. 60 When the proud steed shall know why Man restrains His fiery course, or drives him o'er the plains: When the dull Ox, why now he breaks the clod, Is now a victim, and now AEgypt's God: Then shall Man's pride and dulness comprehend 65 His actions', passions', being's, use and end; Why doing, suff'ring, check'd, impell'd; and why This hour a slave, the next a deity.
