"While these funds could only cover the first stages in the construction of The Brain," he calmly went on, "we have been able to build a mechanical cortex mantle composed of ninety billion electronic cells. Considering that the cortex mantle of the human brain contains over 9 billion cells, this doesn't sound like much. Our synthetic or mechanical cells are a little better than the organic, natural cells, but not very much. So alone and by themselves their number would indicate only a ten times superiority of The Brain over its human counterpart. If that were all the result of our labors, a brain of, let's say, twice genius capacity, we would be a miserable failure. But then we _have_ achieved a very considerable improvement in the _utilization_ of the The Brain's cortex capacity. In the first place we have full control over the intake of thought impulses; and more important, we use multiple wave lengths in feeding impulses to The Brain and throughout all the impulse-processings. Even the human brain has some capacity of simultaneous thought on different levels of consciousness, but its range in this respect is extremely limited. The Brain by way of contrast operates on two thousand different wave lengths, which means that The Brain can process at least 2000 problems at one time. Finally, the absence of fatigue in The Brain makes operations possible for 20 out of the 24 hours of the day--the rest of the time we need for servicing and overhauling." * * * * * With apparent effort Scriven turned his face away from the blue flames. His dark brown eyes probed into Lee's as he summed up: "All together, Lee, The Brain has now reached the approximate capacity of 25,000 first class human brains. You as a man of vision will understand what that means...." Lee had his face upturned. The tension of thought gave to his features something of the ecstatic or the somnambulist. Slowly he said: "The equivalent of twenty-five-thousand human brains--there is no comparison other than a God's...." Striven had jumped from his chair. He started pacing the flagstones in front of the fire, whirling his mighty frame around at every corner with a sort of wrath, as if about to meet some attack. "Yes, you are right," he almost shouted, "we hold that power; that power almost of a God's. And how we are wasting it." "What do you mean?" Lee's eye-brows shot up. "You would not waste those powers once you have them. You would turn them to the most constructive use--the advancement of science, of humanity!" Scriven froze in his steps. A cruel smile parted his lips; there was a gnashing sound of big white teeth. He pointed a finger at his visitor.
