Boundaries....................

55.  The general wickedness of mankind cannot injure the universe;  nor can the particular wickedness of one man injure a fellow man.  It harms none but the culprit himself;  and he can free himself from it as soon as he so chooses.


56.  My neighbor's will is no greater concern to my will than his breath or his flesh.  No matter how much we are made for one another, still each man's self has its own sovereign rights.  Otherwise, my neighbor's wickedness would become my evil;  and God has not willed this, lest the ruin of my happiness should lie at another's disposal.


-Marcus Aurelius,  Meditations,  Book VIII
