"History itself is the only arbiter of "dangerous thoughts" and to whom they are dangerous. For the world does move. Men's thoughts change as the times change. You can no more freeze the thoughts of mankind than you can stop the earth from moving on its axis, than you can freeze a lovely face into eternal youth. To try to do this is not only to make a mockery of democracy, it is to stop the movement of progress and to whip up a fierce tide of reaction. Who should have the right to determine that another man's thoughts are "dangerous"? ("Jailed for her Thoughts")"
