Inspired by Voltaire's two-year stay in England (1726-8), this is one of the key works of the Enlightment. Exactly contemporary with Gulliver's Travels and The Beggar's Opera, Voltaire's controversial pronouncements on politics, philosophy, religion, and literature have place the Lettersamong the great Augustan satires. Voltaire wrote most of the book in English, in which he was fluent and witty, and it fast became a bestseller in Britain. He re-wrote it in French as the Lettres philosophiques, and current editions in English translate his French. This edition restores for the modern reader Voltaire's own Englishtext, allowing us to appreciate him as a stylist at first hand. It is the only critical edition of the original text and, as well as providing an introduction and notes, it includes intriguing accounts of Voltaire by contemporary English ovservers.
