" It isn't only political power that grows out of the barrel of a gun. So does a whole definition of reality. A set. And the action that has to happen on that particular set and on none other."

"Don't be so bloody patronizing," I objected.... "That's just Marx: the ideology of the ruling class becomes the ideology of the whole society."

"Not the ideology. The Reality." He lowered his handkerchief. "This was a public park until they changed the definition. Now, the guns have changed the Reality. It isn't a public park. There's more than one kind of magic."

"Just like the Enclosure Acts," I said hollowly. "One day the land belonged to the people. The next day it belonged to the landlords."

"And like the Narcotics Acts," he added. "A hundred thousand harmless junkies became criminals overnight, by Act of Congress, in nineteen twenty-seven. Ten years later, in thirty-seven, all the pot-heads in the country became criminals overnight, by Act of Congress. And they really were criminals, when the papers were signed. The guns prove it. Walk away from those guns, waving a joint, and refuse to halt when they tell you. Their Imagination will become your Reality in a second. "
