That's probably important when interpreting the intent of this list.

When you add in the inescapable and as yet poorly understood effects of our (post?)modern age's increasing atomization and alienation of society, peeling us all away from each other in order to create completely isolated, undifferentiated monads of purest anti-social solopsistic individuality, it's a wonder this type of delusion isn't more widespread.
