The New Open Door

"But then flooding schools with people with mental problems and then arming professors seems like a hell of a way to run a railroad. Somewhere we have stumbled over a contradiction in our attitudes to modern life: that in pursuing our most altruistic instincts we have also opened the door to dangers against which we must defend ourselves. When we come forward with an open hand we are at our most vulnerable. Open societies are places of great possibility, for both good and evil."
