Matthew Arnold's essay criticizes poetry and criticism. He argues that poetry will provide enduring comfort through its ideas. Arnold proposes evaluating poetry through "real," "historic," and "personal" estimates. The "real estimate" judges poetry objectively based on creative merit, while the "historic estimate" prioritizes historical context over artistic value. The "personal estimate" relies on subjective tastes. Arnold advocates the "touchstone method" of comparing works to classics like Homer, Dante and Shakespeare to assess poetic quality. He analyses various poets like Chaucer, Dryden and Pope through this framework.
