Alexander Pope

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.
Alexander Pope
Essay On Criticism 39; Miscellaneous Poems and Translations: by Several Hands (1720), 38.
Pope is fast becoming my favourite poet.
