Browning is now popularly known for such poems as Porphyria's Lover, My Last Duchess, How They Brought the Good News from Ghent to Aix, and The Pied Piper of Hamelin, and also for certain famous lines: "Grow old along with me!" (Rabbi Ben Ezra), "A man's reach should exceed his grasp" (Andrea Del Sarto), and "God’s in His heaven—All’s right with the world!" (Pippa Passes).
His critical reputation rests mainly on his dramatic monologues, in which the words not only convey setting and action but reveal the speaker's character. In a Browning monologue, unlike a soliloquy, the meaning is not what the speaker voluntarily reveals but what he inadvertently gives away, usually while rationalising past actions or special pleading his case to a silent auditor. These monologues have been influential, and today the best of them are often treated by teachers and lecturers as paradigm cases of the monologue form. Ian Jack, in his introduction to the Oxford University Press edition of Browning's poems 1833–1864, comments that Thomas Hardy, Rudyard Kipling, Ezra Pound and T. S. Eliot "all learned from Browning's exploration of the possibilities of dramatic poetry and of colloquial idiom".
His work has nevertheless had many detractors, and most of his voluminous output is not widely read. In a largely hostile essay Anthony Burgess wrote: "We all want to like Browning, but we find it very hard." Gerard Manley Hopkins and George Santayana were also critical. The latter expressed his views in the essay "The Poetry of Barbarism," which attacks Browning and Walt Whitman for what he regarded as their embrace of irrationality.
