Candide - by Voltaire Audiobook Read by Michael York 

Candide (1759) - Humorous, biting, and satirical, Voltaire’s famous book tells the story of the optimist Candide. Taught that everything is for the best by his professor, Candide then sets out into the world and learns difficult lessons from the school of hard knocks. He maintains his optimistic view as long as he can. However, after a while his confidence in this simpleton philosophy begins to erode. But don’t worry, the honest Candide develops a new outlook to make the best of his life. Enjoy!
