We must soften into a credulity below the milkiness of infancy to think all men virtuous. We must be tainted with a malignity truly diabolical, to believe all the world to be equally wicked and corrupt.
There is no safety for honest men except by believing all possible evil of evil men.
All that is necessary for evil to succeed is for good men to do nothing as they must if they believe they can do nothing. There is nothing worse because the council of despair is declaration of irresponsibility; it is Pilate washing his hands.
