Apperception 36, Lee's lab within The Brain, looked much like Apperception 27 except for its interior fittings. As a matter of fact, all the several hundred Apperception Centers were built after the same plan, like suites in a big office building in many respects. They were spread over The Brain occipital region; they were built inside the concrete wall of the "dura matter" which in turn lay within the shell of the "bone matter", a mile or so of solid rock. Each apperception center had its own elevator shaft which went through the concrete of the "dura matter" down to "Grand Central", the traffic center below The Brain. Each one was also connected at the other end of its corridor with the glideways which snaked through the interior of The Brain. There were, however, no transversal or direct communications from one apperception center to the next. Because of the extraordinary diversity and secrecy of the projects submitted to The Brain' processings, each apperception center was completely insulated against its neighbors. Life hadn't changed so much from what it had been in the Australian desert Lee had found; at least not his working life. For all he knew some nuclear physicists might be working in the lab next door; or they might be ballistics experts working with The Brain on curves for long-range rockets to be aimed at the vital centers of some foreign land; it might be some mild looking librarian submitting the current products of foreign literature to the analysis as to "idea-content"; or else it could be a lab to plot campaigns of chemical warfare; or some astronomer, happily abstracted from all bellicose ideas, might employ The Brain's superhuman faculties in mathematics to figure comet courses and eclipses which in turn would form material for the timing and the camouflaging of those man-made meteorites science would use in another war. Directly or indirectly, he knew, practically every project submitted to The Brain would be of a military nature. Of this there could be no doubt. Sometimes, especially when tired, he could feel the weight of those billions of rock tons over his head and it was like being buried alive in the tomb of the Pharaoh. And also in that state of mental exhaustion at the end of a long day, he sensed the emanations of The Brain's titanic cerebrations as one senses the presence of genius in human man. The knowledge that all this mighty work was being devoted to war had deeply depressing effects on him. Would there be anybody else in this vast apperception area who worked for the prevention of war? A few perhaps; Scriven would be one of them in case he had a lab somewhere in here and time to work in it. Lee didn't know whether he had. He hadn't seen Scriven again after that inauguration speech he had made when Lee, together with other newly appointed scientific workers had taken "The Oath of The Brain."
