One's mind should give orders, not take them. We are affected by the external only if we foolishly choose to be so affected. One becomes disturbed if he opens the door and lets the storm of external suffering and events rage inside. Thus, the Stoic does not have to seek refuge in a safe haven apart from political affairs. He can immerse himself in practical affairs and still remain mentally calm, as God involves himself in Nature but remains aloof and detached.
Stoicism calls for a universal benevolence towards all humans.
It is our duty to help our fellows. On the other hand, our duty to others should be free of emotional entanglements. The key to peace is detachment. Mind and body are separate compartments. Mental disturbance is caused by wanting and craving what is beyond our power.
