Echoing Milton's purpose in Paradise Lost, Pope says his aim in An Essay on Man is to "vindicate the ways of God to man"--to explain the existence of evil and explore man's place in the universe. In a comprehensive introduction, Tom Jones describes the poem as an investigation of the fundamental question of how people should behave in a world they experience as chaotic, but which they suspect to be orderly from some higher point of view. The introduction provides a thorough discussion of the poem's attitudes, themes, composition, context, and reception, and reassesses the work's place in history. Extensive annotations to the text explain references and allusions.
