Franklin argues that courage is not sufficient by itself to make conduct admirable. A person may show bravery, determination or willingness to face danger, but those qualities have limited moral value if they are used in support of an unjust cause. Justice gives courage direction by connecting bold action with a defensible purpose.

The saying therefore distinguishes between courage as a personal quality and courage as a virtue. Bravery can be used for harmful as well as beneficial ends, so its value depends partly on what it serves. Franklin’s broader point is that strength of character should be guided by fairness and moral judgement. Courage becomes more meaningful when it is exercised in defence of what is right rather than simply demonstrating fearlessness or resolve.
