They are afraid of words and thoughts; words spoken abroad, thoughts stirring at home — all the more powerful because forbidden — terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic. They make frantic efforts to bar our thoughts and words; they are afraid of the workings of the human mind. — “The Defence of Freedom and Peace (The Lights are Going Out)”, radio broadcast to the United States and to London (16 October 1938)

My Take – If you are afraid to let the truth see the light of day, you’re probably doing something either illegal or immoral.  Stop it, you might go blind.
