Some believe “ignorance is bliss”, and the more they know the more they get worried. On the other hand we definitely can’t be indifferent about many things. From a social perspective, through which we try to manage our relationship with others in a friendly manner, what is the borderline between legitimate worry (which leads to taking action) and indifference (which preserve peace of mind, at least in the short term)? Is it morally permissible to encourage other people to worry about certain issues, say global warming, human rights, animal rights, etc. to precipitate effective action? Should we consider them selfish if they are innately not concerned about such issues, or merely show token agreement?
