Political Justice was revered by the first generation of Romantic poets, such as William Wordsworth and Samuel Taylor Coleridge, although they would later turn away from radicalism. However, as Romantic scholar Andrew McCann explains, "it is in the radicalism of Percy Shelley's work that Godwin's thinking exerted its greatest influence on the Romantic movement, and ... Shelley's work was most central to the resurgence of radical sentiment after the end of the Napoleonic Wars."

Enquiry Concerning Political Justice and its Influence on Morals and Happiness (1793) outlines the political philosophy of the 18th-century philosopher William Godwin. Despite being published during the French Revolution, the French Revolutionary Wars, and the lead up to the 1794 Treason Trials in Britain, Political Justice argues that humanity will inevitably progress: it argues for human perfectibility and enlightenment. McCann explains that "Political Justice is ... first and foremost a critique of political institutions. Its vision of human perfectibility is anarchist in so far as it sees government and related social practices such as property monopoly, marriage and monarchy as restraining the progress of mankind." Godwin believed that government "insinuates itself into our personal dispositions, and insensibly communicates its own spirit to our private transactions". Instead, Godwin proposes a society in which human beings use their reason to decide the best course of action. The very existence of governments, even those founded through consensus, demonstrates that people cannot yet regulate their conduct by the dictates of reason.

William Godwin (3 March 1756 – 7 April 1836) was an English journalist, political philosopher and novelist. He is considered one of the first exponents of utilitarianism, and the first modern proponent of anarchism. Godwin is most famous for two books that he published within the space of a year: An Enquiry Concerning Political Justice, an attack on political institutions, and Things as They Are; or, The Adventures of Caleb Williams, which attacks aristocratic privilege, but also is the first mystery novel. Based on the success of both, Godwin featured prominently in the radical circles of London in the 1790s. In the ensuing conservative reaction to British radicalism, Godwin was attacked, in part because of his marriage to the pioneering feminist writer Mary Wollstonecraft in 1797 and his candid biography of her after her death; their daughter, Mary Godwin (later Mary Shelley) would go on to write Frankenstein and marry the poet Percy Bysshe Shelley. Godwin wrote prolifically in the genres of novels, history and demography throughout his lifetime. With his second wife, Mary Jane Clairmont, he wrote children's primers on Biblical and classical history, which he published along with such works as Charles and Mary Lamb's Tales from Shakespeare. Using the pseudonym Edward Baldwin, he wrote a variety of books for children, including a version of Jack and the Beanstalk. He also has had considerable influence on British literature and literary culture.
