“The difference between raman and varelse is not in the creature judged, but in the creature judging. When we declare an alien species to be raman, it does not mean that they have passed a threshold of moral maturity. It means that we have.”

The difference between raman and varelse is not in the creature judged but in the creature judging, and when we declare an alien species to be raman, it does not mean that they have passed a threshold of moral maturity. It means that we have.”

“Never judge anyone by another's opinions. We all have different sides that we show to different people.”
