John Dryden is considered the father of English criticism. He introduced several new concepts and approaches to literary criticism compared to previous critics. Dryden was the first to practice original, liberal, descriptive, historical, comparative, and theoretical criticism in England. He analyzed works in detail and tested classical rules in light of modern times. Dryden also believed poetry should delight rather than just instruct, and viewed drama as a creative imitation of life that was not strictly bound by classical rules like the three unities. He helped establish criticism as its own art form in England.
