Philip K. Dick quotes - page 6
The living, he thought, should never be used to serve the purposes of the dead. But the dead-he glanced at Bruce, the empty shape beside him - should, if possible, serve the purposes of the living.
That, he reasoned, is the law of life.
And the dead, if they could feel, might feel better doing so.
The dead, Mike thought, who can still see, even if they can't understand: they are our camera.
