Summary
Epictetus emphasizes that the true power of a human being lies in their reasoned choice. This inner power, which allows us to make decisions and control our responses, is the highest form of authority we possess. Unlike external forces or circumstances, our reasoned choice is entirely under our control and free from any external master or influence.

Interpretation
In practical terms, this means recognizing that our greatest strength comes from within us, specifically from our ability to choose how we respond to situations. For someone familiar with Stoic teachings, this reinforces the idea that while we cannot control external events, we can always control our own decisions and reactions. By focusing on this internal power, we can navigate life’s challenges with greater autonomy and resilience, understanding that our true freedom and authority reside in how we exercise our reasoned choices.
