The world has progressed to the point where it's most powerful force is public opinion. And I believe that in this world it is not the great book or epic play, as once was the case, that will shape that opinion, but those who understand mass media and the techniques of mass persuasion...We must not just believe in what we sell. We must sell what we believe in. And we must pour a vast energy into those causes.
