The Philosophical Letters or Letters on the English (French: Lettres philosophiques) is a 1733 work by Voltaire, revised in 1778, composed as a series of letters reflecting on his sojourn in England from 1726 to 1728.
Voltaire's thoughts on English literature include a number of leading writers of the day who he met while in London, such as Alexander Pope and Jonathan Swift. His account of English political and religious institutions, Newtonian science, and the empiricism of Bacon and Locke, quickly became a formative influence on continental liberalism.
