Alexander Pope's "An Essay on Criticism" seeks to lay down rules of good taste in poetry criticism, and in poetry itself. Structured as an essay in rhyming verse, it offers advice to the aspiring critic while satirizing amateurish criticism and poetry. The famous passage beginning "A little learning is a dangerous thing" advises would-be critics to learn their field in depth, warning that the arts demand much longer and more arduous study than beginners expect. The passage can also be read as a warning against shallow learning in general. Published in 1711, when Alexander Pope was just 23, the "Essay" brought its author fame and notoriety while he was still a young poet himself.
