Wordsworth was an autobiographical poet in the late 18th and early 19th century who focused on the connection between childhood and nature. He believed that adults should maintain the same happiness and simplicity as children. Wordsworth started his career protesting war and industrialization, but later became more conservative. He published Lyrical Ballads with Coleridge in 1798, which expressed how nature could educate one's senses, mind, and foster goodness through imagination and simple language seen through a child's perspective. The collection was an influential work and manifesto of the Romantic movement.
