Solidarity
By Marcus Aurelius
(Roman emperor, A.D. 121-180)
As thou thyself, whoever thou art, wert made for the perfection and consummation of a common society; so must every action of thine tend to the perfection and consummation of a life that is truly sociable. Whatever action of thine that, either immediately or afar off, hath not reference to the common good, that is an exorbitant and disorderly action; yea, it is seditious; as one among the people who from a general consent and unity should factiously divide and separate himself.
