"I'll be all right. I just need a few days real work." He stopped. "No, that's not why. I'm confused. I've been reading crazy things about obsolescence. They used to have strange reasons for it. Why, some people even said replacements were not always improvements and were unnecessary!"

Burnett could not completely hide his pleasure. "You've been getting into rather deep stuff."

"Deep—or nonsensical!"

"True. True. Come back tomorrow and read some more."

"Maybe I will." But he was happy to get away from the library building.

Marie was horrified when he told her that evening about his studies. "Don't go back there," she pleaded. "It's dangerous. It's subversive! How could people say such awful things? You remember that Mr. Johnson around the corner? He seemed such a nice man, too, until they arrested him without giving a reason ... and how messed up he was when he got out last year. I'll bet that kind of talk explains the whole thing. It's crazy. Everyone knows items start wearing out and they have to be replaced."

"I realise that, honey, but it's interesting to speculate. Don't we have guaranteed freedom of thought?"

She threw up her hands as if dealing with a child. "Naturally we have freedom of thought. But you should have the right thoughts, shouldn't you? Wendell, promise me you won't go back to that library."

"Well—"

"Reading's a very risky thing anyway." Her eyes were saucer-round with fright. "Please, darling. Promise."
