Context

“He must be ever active to do his part in the great whole. All men are his kin, not only in blood, but still more by participating in the same intelligence and by being a portion of the same divinity. A man cannot really be injured by his brethren, for no act of theirs can make him bad, and he must not be angry with them nor hate them: "For we are made for co-operation, like feet, like hands, like eyelids, like the rows of the upper and lower teeth. To act against one another then is contrary to nature; and it is acting against one another to be vexed and to turn away"” source
