A lie's true power cannot be accurately measured by the number of people who believe its deception when it is told, it must be measured by the number of people who will go out after hearing it trying to convince others of its truth.

Summary

This quote suggests that the true power of a lie cannot be determined merely by the number of people who fall for its deception when it is initially told. Instead, its true power lies in the number of individuals who are motivated to spread the lie and convince others of its truth, even after hearing it themselves. This highlights the dangerous nature of falsehoods, as they have the potential to perpetuate and influence a much larger number of people through word-of-mouth and persuasion.
