Winston Churchill on Freedom of speech

“So we must beware of a tyranny of opinion which tries to make only one side of a question the one which may be heard. Everyone is in favour of free speech. Hardly a day passes without its being extolled, but some people’s idea of it is that they are free to say what they like, but if anyone says anything back, that is an outrage.”

“But arms – instrumentalities, as President Wilson called them – are not sufficient by themselves. We must add to them the power of ideas. People say we ought not to allow ourselves to be drawn into a theoretical antagonism between Nazidom and democracy; but the antagonism is here now. It is this very conflict of spiritual and moral ideas which gives the free countries a great part of their strength. You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police. On all sides they are guarded by masses of armed men, cannons, aeroplanes, fortifications, and the like – they boast and vaunt themselves before the world, yet in their hearts there is unspoken fear. 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. Cannons, airplanes, they can manufacture in large quantities; but how are they to quell the natural promptings of human nature, which after all these centuries of trial and progress has inherited a whole armoury of potent and indestructible knowledge?”
