Franklin presents the ant as a silent teacher of industry. Its constant activity, preparation and persistence provide an example without the need for spoken instruction. By saying that the ant “preaches”, he compares observable behaviour with a moral lesson, suggesting that conduct can communicate values more effectively than advice alone.

The saying reflects a long tradition of using the ant as a symbol of diligence and preparation. Franklin’s emphasis is not on the animal’s biology in a literal sense, but on what people can learn from watching purposeful action. His broader point is that example has persuasive force because it demonstrates a principle rather than merely describing it. Someone who consistently practises diligence may therefore teach its value more convincingly than someone who speaks about hard work without showing it in their own behaviour.
