“A good enemy can be more valuable than a good ally”

The expression “a good enemy can be more valuable than a good ally” recasts opposition as a possible source of insight and leverage. Spoken as the master’s strategic principle and applied to the danger of an approaching ship, it gives John Blackthorne a task that begins not with defeating an adversary but with understanding how to influence one.

Meaning and Form

The maxim balances “enemy” against “ally,” then overturns the expected ranking: an opponent may be more useful than a supporter. Its force lies in the conditional idea of value, not in any claim that hostility is harmless. The surrounding exchange makes clear that the ship’s cannons pose a real danger; the saying offers a way to think through that danger rather than denying it.

Use in the Exchange

The statement follows Blackthorne’s warning that his side is exposed and could be sunk if the ship is hostile—or even neutral. He is told that the master expects an answer and that it is his duty to persuade the ship’s crew to be benevolent. Blackthorne objects that he is their enemy. The maxim answers that objection by treating his adversarial position as a reason he may be able to understand their thinking and find a way to persuade them.

Strategic Consequence

The exchange does not leave the maxim as an abstract lesson. Blackthorne says force is the only sure method; the master agrees, then asks how he would pirate the ship. That turn joins persuasion to coercive planning: understanding an enemy may serve peaceful negotiation, but it may also help make force effective. The expression therefore captures a practical uncertainty in the scene, where diplomacy and piracy remain competing possibilities.
