“It seemed to me that a great many fences had been put up all over the world, in the long course of history, that were not necessary. Fences round nations, fences round property. They were supposed to be symbols of security, but they were cheating symbols. They had a precisely opposite effect from that which was intended. They did not prevent crime, they incited it; they led not to peace but to war. A world without fences would be a better world.”
