Phillip K. Dick's letter to the FBI where he denounces Thomas Disch's "Camp Concentration" for containing coded neo-Nazi messages "to be read by the right people here and there" Curiously, in other correspondence he gave it the highest praise.

Look around you at the environment we live in. Carbon dioxide, flourocarbons, and methane have increased since 1968. Earth is being aclimatized. They are turning our atmosphere in to their atmosphere. We are like a natural resource to them. Deplete one planet, move on to another. They want benign indifference. They want us drugged. We could be pets. We could be food. But all we really are is livestock.
Our impulses are being redirected. We are living in an artificially induced state of consciousness that resembles sleep. They have created a repressive society and we are their unwitting accomplices. Their intention to rule rests with the annihilation of consciousness. We have been lulled in to a trance. They have made us indefferent to ourselves, to others. We are focused only on our own gain.

--John Carpenter's "They Live"
