Stoic Snippets 186

To my own free will the free will of my neighbor is just as indifferent as his poor breath and flesh. 

For though we are made especially for the sake of one another, still the ruling power of each of us has its own office, for otherwise my neighbor's wickedness would be my harm, which God has not willed, in order that my unhappiness may not depend on another. 

—Marcus Aurelius, Meditations 8.56
