We have two ears and one mouth so that we can listen twice as much as we speak.

The saying uses a simple anatomical observation—two ears, one mouth—to argue for a moral discipline: prioritize listening over talking. In a broadly Stoic spirit, it implies that wisdom and self-command grow from attention, restraint, and receptivity rather than from asserting oneself. Listening becomes a practice of humility and of learning from reality and other people, while excessive speech risks impulsiveness, vanity, and error. The aphorism’s enduring appeal lies in its memorable proportional rule (“twice as much”) that turns everyday biology into an ethical reminder about communication and character.
