She shrugged. "I can't help it. We were doing physiology of the sensory organs, trying to settle the oldie about focusing the eye, and I got to grubbing around the pre-Lieberman texts looking for light in the darkness. Some of it sounded so--not sensible, but _positive_ that I ran off one of Lieberman's population checks. And the old boy had been dead wrong. _Mengenlehre_ constructs correspond quite nicely to the actual way people's minds work. I kept checking and the schools that were destroyed as hopelessly fallacious a century ago checked out, some closely and some not so closely, as good descriptions of the way the mind works. Some have predictive value. I used _mengenlehre_ psychology algorithms to compute the conditioning on you and me, including the trigger release. It worked. You see, Charles? We're on the rim of something tremendous!" "When did this Lieberman flourish?" "I don't have the exact dates in my head. The breakup of the schools corresponded roughly with the lifetime of John G. Falcaro." That pin-pointed it rather well. John G. succeeded Rafael, who succeeded Amadeo Falcaro, first leader of the Syndic in revolt. Under John G., the hard-won freedom was enjoyed, the bulging store-houses were joyously emptied, craft union rules went joyously out the window and builders _worked_, the dollar went to an all-time high and there was an all-time number of dollars in circulation. It had been an exhuberant time still fondly remembered; just the time for over-enthusiastic rebels against a fusty scholasticism to joyously smash old ways of thought without too much exercise of the conscience. It all checked out. She started and he got to his feet. A hardly-noticed discomfort was becoming acute; the speedboat was pitching and rolling quite seriously, for the first time since their escape. "Dirty weather coming up," he said. "We've been too damned lucky so far." He thought, but didn't remark, that there was much to worry about in the fact that there seemed to have been no pursuit. The meager resources of the North American Navy wouldn't be spent on chasing a single minor craft--not if the weather could be counted on to finish her off. "I thought we were unsinkable?" "In a way. Seal the boat and she's unsinkable the way a corked bottle is. But the boat's made up of a lot of bits and pieces that go together just so. Pound her for a few hours with waves and the bits and pieces give way. She doesn't sink, but she doesn't steam or steer either. I wish the Syndic had a fleet on the Atlantic." "Sorry," she said. "The nearest fleet I know of is Mob ore boats on the great lakes and they aren't likely to pick us up." The sea-search radar pinged and they flew to the screen. "_Something_ at 273 degrees, about eight miles," he said. "It can't be pursuit. They couldn't have any reason at all to circle around us and come at us from ahead." He strained his eyes into the west and thought he could see a black speck on the gray.
