Context

“we might imagine the solar system resolved into its elemental parts, and yet the whole would still subsist "ever young and perfect." All things, all forms, are dissolved, and new forms appear. All living things undergo the change which we call death. If we call death an evil, then all change is an evil. Living beings also suffer pain, and man suffers most of all, for he suffers both in and by his body and by his intelligent part. Men suffer also from one another, and perhaps the largest part of human suffering comes to man from those whom he calls his brothers. Antoninus says (viii. 55) , "Generally, wickedness does no harm at all to the universe;” source
