Great is truth, but still greater, from a practical point of view, is silence about truth. By simply not mentioning certain subjects... totalitarian propagandists have influenced opinion much more effectively than they could have by the most eloquent denunciations.
The greatest triumphs of propoganda have been accomplished, not by doing something, but by refraining from doing. Great is truth, but still greater, from a practical point of view, is silence about truth.
Silence is as full of potential wisdom and wit as the unshown marble of great sculpture. The silent bear no witness against themselves.
