1. Matthew Arnold introduced the touchstone method of literary criticism to evaluate poetry. He proposed using passages from known classics as "touchstones" to test the quality of contemporary works.
2. According to Arnold's method, a work is considered a true classic if it moves the reader in the same way as passages from great masters like Homer, Dante, Shakespeare, and Milton.
3. The touchstone method provides an objective standard for evaluation that avoids the subjectivity of personal taste or overemphasis on a work's historical importance rather than poetic merit.
