Alfred Lanning Peter Bogert Milton Ashe and Susan. A Calvin sat around a table. Lanning the director of U.S. Robots spoke first. The robot reads minds he aid. We're sure about that. But we don't know why. He looked at Bogert. You're the mathematician. You know how the positronic brains of robots are built. You explain. We're talking about the thirty fourth RB model of robot Bogert said. All the other RB models are normal. Do you? Bogert said unpleasantly. We have to complete 75,234 procedure when we make one positronic brain. And any of them can go wrong. That's true Dr Calvin he said. We've made a positronic brain that can read minds. This could be the most important robotic development. We have to know how the robot can read minds. Bogert I right Calvin sald. You were alone when you discovered the truth about RB 34 weren't you? Yes Iwas Ashe replied. After RB 34 was built the scientist sent him to me. I was thinking about something and he spoke to me about it. Then I relized that I hadn't said anything I look the robot into a room locked the door and went to tell Lanning.
