We're sane.--How do we know?--That we're sane?--Yes.--Am I sane?--To all appearances.--And you, do you consider yourself sane?--I do.--Well, there you have it.--But don't they also consider themselves sane?--I think they know. Deep down. That they're not sane.--How must that make them feel?--Terrible, I should think. They must fight ever more fiercely, in order to deny what they know to be true. That they are not sane.”
