'Pirate Illustration' promises a lot, but turns out to be gibberish. American anthropologist and activist David Graeber was a brilliant, rebellious and iconoclastic thinker.

Blackbeard or the fictional Long John Silver and Sparrow would probably be surprised that we can see them as proletarian figures of liberation. Their ships, whether Queen Anne's Revenge, The Hispaniola, or The Black Pearl waved the flag of utopia alongside the Jolly Roger.
