Sympatheia (συμπάθεια): sympathy, affinity of parts to the organic whole, mutual interdependence.
Revere the gods, and look after each other. Life is short—the fruit of this life is a good character and acts for the common good.”
— Marcus Aurelius, Meditations, 6.30
“Meditate often on the interconnectedness and mutual interdependence of all things in the universe. For in a sense, all things are mutually woven together and therefore have an affinity for each other—for one thing follows after another according to their tension of movement, their sympathetic stirrings, and the unity of all substance.”
—Marcus Aurelius, Meditations, 6.38
