From 1984 by George Orwell;
Who controls the past controls the future. Who controls the present controls the past.
Up until I read 1984 a few years ago I thought that quote was from the song "Testify" by Rage Against the Machine.

As to required reading, there has definitely been a "dumbing down" of the required reading in my area. When I was in fourth grade "Hatchet" by Gary Paulsen was required reading. For my brother it was sixth grade required reading. I wonder if that means kids are, on average, two years behind where I was at their age academically (at least in that school system).
