Williams, after explaing his ideas on ‘social beings’ says: ‘A nation has the same sort of "right" (or lack thereof) to cause itself suffering as I do — but it isn’t "right" for either the nation or myself to cause ourselves suffering’.
What if the ‘nation’ sees it as ‘medically necessary’ to excise troublesome political opponents from its ‘body’??
Then it still has just as much right (or lack thereof) as I. Is it right? I don’t know. You’ll have to give a specific example. Most of the time nations are wrong in their judgements on this — they have not fully analysed the interdependence of causes. Basically, they are setting themselves up for another round of suffering. How is this different than the average human?
