John Green teaches you about Voltaire's hugely important Enlightenment novel, Candide. Candide tells a pretty wild story, but for the most part, it's about the best of all possible worlds. Which, spoiler alert, doesn't seem to be the best of all possible worlds. Voltaire's novel is a pretty frank look at Enlightenment philosophy that finds a lot of the thinking of the time wanting. It's also got lots of sex, death, and travel!
