Practical Criticism

This is a method of approaching a text, often a poem, where the reader or student is given no background information about authorship, date or background. The analysis must therefore concentrate on the words on the page and devices used. It has fallen out of fashion recently since its promotion by I. A. Richards in the 1920's but it can be a useful method of ensuring a fresh response to a work.
