The Skeptic's Walk (French: La Promenade du sceptique)[1][2] is a book by Denis Diderot, completed in 1747.
The book was reportedly lost in police custody, and remained unheard of until it was put up for auction by a Paris bookseller in 1800.
Part of the book presents a fictional story, set shortly after the Battle of Fontenoy, involving a small group of philosophers.
The book ends with the narrator of the story meeting "one of those blondes whom a philosopher ought to avoid", who convinces him that it is better to embrace happiness on earth than to wait for it in heaven.
[3] The book has been described as being highly satirical, and whilst it mainly criticises the Christian churches, it has also been called Diderot's "most unkind treatment of Judaism and the ancient Jews.
