Variant: We're not teaching kids to read and write and think. … There's no reason to burn books if you don't read them.
As quoted in "At 80, Ray Bradbury Still Fighting the Future He Foresaw" http://www.raybradbury.com/articles_peoria.html, interview by Roger Moore, in The Peoria Journal Star (August 2000)
Kontext: The problem in our country isn't with books being banned, but with people no longer reading. Look at the magazines, the newspapers around us – it's all junk, all trash, tidbits of news. The average TV ad has 120 images a minute. Everything just falls off your mind. … You don't have to burn books to destroy a culture. Just get people to stop reading them.

Quotation is from the October 3, 2000 Presidential debate with Al Gore, but is taken out of context. Bush was paraphrasing Colin Powell and Norman Schwarzkopf:
The other day, I was honored to be flanked by Colin Powell and General Norman Schwarzkopf, who stood by my side and agreed with me. They said we could, even though we're the strongest military, that if we don't do something quickly, we don't have a clearer vision of the military, if we don't stop extending our troops all around the world in nation-building missions, then we're going to have a serious problem coming down the road. And I'm going to prevent that. I'm going to rebuild our military power. It's one of the major priorities of my administration. http://www.cnn.com/ELECTION/2000/debates/transcripts/u221003.html

Kontext: I'm going to stop squandering money for things I don't want. I'm going to stop accepting invitations, and meeting people I don't like and don't want to know. I've tried your game — I've tried it hard, and I don't like it; and I'm going to get out before it's too late. I'm going to find some decent and simple place to live in; and I'm going down town to find out if there isn't some way in New York for a man to earn an honest living!
