The Physician, by the study and inspection of urine and ordure, approves himself in the science; and in like sort should our author accustom and exercise his imagination upon the dregs of nature.
First follow Nature, and your judgment frame
By her just standard, which is still the same:
Unerring nature, still divinely bright,
One clear, unchanged, and universal light,
Life, force, and beauty must to all impart,
At once the source, and end, and test of art.
Whoever thinks a faultless piece to see, Thinks what ne'er was, nor is, nor e'er shall be, In every work regard the writer's end, Since none can compass more than they intend; And if the means be just, the conduct true, Applause, in spite of trivial faults, is due.
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.
