The wisest thing in the world is to cry out before you are hurt. It is no good to cry out after you are hurt. People talk about the impatience of the populace; but sound historians know that most tyrannies have been possible because men moved too late. It is often necessary to resist a tyranny before it exists. It is no answer to say, with a distant optimism, that the scheme is only in the air. A blow from a hatchet can only be parried while it is in the air.
– G K Chesterton, ‘Eugenics and Other Evils’
