That’s the nature of the social and rational animal we are. We’re designed to live among other human beings, very much like bees, says Musonius Rufus: “A bee is not able to live alone: it perishes when isolated.” And Marcus conveniently adds, “What brings no benefit to the hive brings none to the bee.” Our actions must benefit the common welfare, or they won’t benefit ourselves. We’re like a massive organism: all depending on one another.
