The names of both of the ships Billy serves on are significant. He is originally a sailor on the Rights-of-Man, which the narrator notes takes its name from a book by Thomas Paine. Paine's book, which played an influential role in pushing the American colonies toward the American Revolution, essentially argues that political revolution is justified when a government fails to protect individual rights. Paine's book thus affirms the rights of individuals over the interests of society at large. The Rights-of-Man, then, can be seen as symbolizing the importance of individual rights. When Billy is forced to leave this ship and says "good-bye to you too, old Rights-of-Man," he bids farewell to his own personal rights, which have been trumped by the navy. The naval ship Billy joins has an equally significant name: the Indomitable (in some editions, the Bellipotent). This ship name symbolizes the indomitable, unbeatable force of society (for the Bellipotent, the power of war), which curtails the individual rights of the sailors, many of whom have been forcibly conscripted into naval service. The ship names in Melville's novella thus encapsulate the narrative's central conflict between individuals and society.
