“”Justice being taken away, then, what are kingdoms but great robberies?” … Indeed, that was an apt and true reply which was given to Alexander the Great by a pirate who had been seized. For when that king had asked the man what he meant by keeping hostile possession of the sea, he answered with bold pride, “What you mean by seizing the whole earth; but because I do it with a petty ship, I am called a robber, while you who does it with a great fleet are styled emperor””
