Where is the Plan?
This time, there was a return of the tootling and loud tweetling throughout the vastness of the Brain, as it searched through its every memory circuit before quieting and typing the solitary word: Null.
"The question's not applicable?" Andra said, leaning over Lloyd's shoulder to read the paper. "It must be!"
"Quiet! Let me think!" Lloyd snapped, irritably. "The word 'null' can also mean it doesn't have the knowledge.... Let me try another question—" He typed slowly: Who knows where the Plan can be found?
Secondary Speakster.
"We've got to go and ask him where the Plan is!" She clutched at his arm.
"Wait!" Lloyd said, "I have to find out one more thing." Andra stood waiting impatiently while Lloyd typed: How can the robots be made inoperable?
They cannot so long as the Brain persists.
"Damn!" Lloyd muttered, and typed: If the Brain will only persist till Man has knowledge, will the Brain let Man study the Plan that will give him knowledge?
It must prevent Man from getting knowledge.
