As nightfall does not come at once, neither does oppression. In both instances, there is a twilight when everything remains seemingly unchanged. And it is in such twilight that we all must be most aware of change in the air – however slight – lest we become unwitting victims of the darkness.
William O. Douglas, The Douglas Letters: Selections from the Private Papers of Justice William O. Douglas
