libertine

"I only ask to be free," says Mr. Skimpole in Charles Dickens' Bleak House, and his words would undoubtedly have appealed to the world's first libertines. The word libertinus was used in early writings of Roman antiquity to describe a slave who had been set free (the Roman term for an emancipated slave was the Latin libertus). The "freedman" sense of libertine was extended to freethinkers, both religious and secular, and later came to imply that an individual was a little too unrestrained, especially in moral situations. The Latin root of libertine is liber, the ultimate source of our word liberty.
