PLEASE NOTE: These books are in French
Drawing on the experiences of his stay in England (1726-1728), the Lettres are made up of a series of short articles, covering a range of themes, from religion and politics to literature, and they aim to present an overall view of contemporary English culture. Voltaire experiments with a new type of cultural history, suggesting the interconnection of religious tolerance, political freedom and a dynamic literary culture.
The first edition to appear was an English translation, published in London in 1733 under the title Letters concerning the English Nation. The original French version followed, entitled Lettres écrites de Londres sur les Anglais, published in 1734, also in London. Thirdly, a rather different French edition was published the same year by the printer Jore in Rouen, under the title Lettres philosophiques: this French edition was immediately censored, and Voltaire was obliged to lie low until the scandal died down.
This is a two volume set, published in 1964 by Librairie Marcel Didier in Paris, Sorbonne.
Although there is some damage to this pair, as they are paperbacks and have no lasted well they are a great thing for anyone learning and reading french philosophy.
