Epictetus, in his work "Discourses and Selected Writings," offers a profound piece of advice on how to deal with people based on their wisdom or foolishness. He suggests that if an individual demonstrates wisdom, engaging in conflict with them is unwise. Instead, one should approach them with respect and understanding. This implies a recognition of their insight and the value they bring to discussions.

On the other hand, if a person acts foolishly, Epictetus advises ignoring them altogether. This approach emphasizes the importance of choosing one’s battles and conserving energy for meaningful engagements. By doing so, individuals can maintain their peace of mind and avoid unnecessary disputes, ultimately leading to a more harmonious existence.
