Samuel Taylor Coleridge was an influential English poet, literary critic, and philosopher in the Romantic era. He helped establish Romanticism in England and his ideas on poetry had a lasting impact. Some of his most famous poems include "Kubla Khan", "The Rime of the Ancient Mariner", and "Frost at Midnight". Coleridge believed that poetry stems from the poetic genius of the writer and modifies their thoughts and emotions. He argued that a poet should borrow from nature accurately but write from their imagination rather than strict memory.
