Redemption lies in the destruction of the walls we surround ourselves with, both as individuals and nations. And it is fear that builds these walls, and it's a fear that's engendered and supported in us by our governments. It makes us much easier to control if we're frightened of other people than if we're not.

We don't need no thought control
