Plato visited his teacher Socrates and said, "You have been spreading false information about me in the market place." Socrates asked, "What have you been telling people?" Plato answered, "You have been telling people about me." Socrates stopped him and told him to think about the situation, analyze it, and then decide if he should tell him the information or not. He asked Plato to consider three criteria, the truthfulness of the information, the morality of the information, and the usefulness of the information. If the information met all three criteria, then he could tell him, but if it did not, then he should keep quiet. Plato argued that the information was true but Socrates pointed out that it may not be useful or moral to spread it. This conversation highlights the importance of considering the truth, morality, and usefulness of information before spreading it.
