How does the novel, Candy, mirror Voltaire's, Candide?

Just as Voltaire's Candide had mocked naive eighteenth-century philosophy that "all is for the best in this best of all possible worlds," so does Candy mock modern permissive ideas that free love, frantic travel, and rabid experimentation in religions, mores, and life-styles are eagerly-to-be-fostered and endured.
