People knew less of each other, perhaps, but they felt more free of each other, and so were more individual. The entire world was not for them only a push or a switch away.

They tore up the commandments, they denied the super-ego, what you will. They said, "You may persecute the minority, you may kill, you may torture, you may couple and breed without love." They offered humanity all its great temptations. Nothing is true, everything is permitted.
