Rousseau’s quote reflects the idea that true knowledge often comes with humility and introspection, while those who talk excessively may do so to cover their lack of understanding. People with deep knowledge understand the complexity of life and are often more thoughtful in their speech, aware of the limitations of what they know. In contrast, individuals who are less informed tend to speak more because they have less awareness of the broader scope of a topic, often overcompensating with words. This serves as a reminder that silence and careful speech can be signs of wisdom, while verbosity might reveal insecurity or a lack of depth.
