Epictetus presents a compelling view of the invincible human being as someone who remains unshaken by external circumstances. This individual understands that true power lies within the realm of personal choice and perception. Instead of being affected by external events or opinions, they maintain inner peace and freedom by focusing only on what they can control.

This perspective emphasizes the importance of self-discipline and mental resilience. By cultivating a mindset that prioritizes autonomy and personal responsibility, one can rise above life's challenges. The belief is that, by mastering our reactions and decisions, we can achieve a sense of invincibility against the tumult of the outside world.
