You can kill a thousand; you can bring an end to life; you cannot kill an idea.
There's no flesh or blood within this cloak to kill. There's only an idea. Ideas are bulletproof.
No idea is ever dead until those who believe in it say it's dead.
You can imprison a man, but not an idea. You can exile a man, but not an idea. You can kill a man, but not an idea.
Governments have always tried to crush reform movements, to destroy ideas, to kill the thing that cannot die. Without regard to history, which shows that no Government have ever succeeded in doing this, they go on trying in the old, senseless way.
You burn the paper, but not the words. You silence the words, but not the thoughts. You kill the thoughts only if you kill the man. And you will find that his thoughts rise again in the minds of others - twice as strong as before.
