"Shall we go in?" the lean man urged.
The woman hesitated. Senator said tactfully, "After all, Doctor Wilson would like you to see his project."
The brown-suited man nodded. His face took on a sharp intensity. "We're making a great mistake. No one is interested in educating the children any more. They leave it to the robots. And they neglect the children's training at home."
The woman turned toward him with surprise in her eyes. "But really, aren't the robots the best teachers?"
"Of course they are. But confound it, we ought to be interested in what they teach and how they teach. What's happened to the old PTA? What's happened to parental discipline, what's happened to—"
He stopped suddenly and smiled, a rueful tired smile. "I suppose I'm a fanatic on this. Come on inside."
They passed through an antiseptic corridor built from dull green plastic. The brown-suited man pressed a button outside one of the classrooms. A door slid noiselessly into the hall. A robot stood before them, gesturing gently. They followed the robot into the classroom. At the head of the classroom another robot was lecturing. There were drawings on a sort of plastic blackboard. There were wire models on the desk in front of the robot. They listened for a moment, and for a moment it seemed that the woman could be intrigued in spite of herself.
"Mathematics," Doctor Wilson murmured in her ear. "Euclidean Geometry and Aristotelean reasoning. We start them young on these old schools of thought, then use Aristotle and Euclid as a point of departure for our intermediate classes in mathematics and logic."
"REAHLLY!" The lorgnette studied Doctor Wilson. "You mean there are several kinds of geometry?"
Doctor Wilson nodded. A dull flush crept into his cheeks. The Senator caught his eyes and winked. The woman moved toward the door. At the door the robot bowed.
