“In other words if a man is armed, then one pretty much has to take his opinions into account. One can see how this worked at its starkest in Xenophon’s Anabasis, which tells the story of an army of Greek mercenaries who suddenly find themselves leaderless and lost in the middle of Persia. They elect new officers, and then hold a collective vote to decide what to do next. In a case like this, even if the vote was 60/40, everyone could see the balance of forces and what would happen if things actually came to blows. Every vote was, in a real sense, a conquest.”
