They tell me: If you see a slave sleeping, do not wake him lest he be dreaming of freedom. I tell them: If you see a slave sleeping, wake him and explain to him freedom.
Nothing is more disgusting than the crowing about liberty by slaves, as most men are, and the flippant mistaking for freedom of some paper preamble like a Declaration of Independence, or the statute right to vote, by those who have never dared to think or to act.

You call yourself free? I want to hear your ruling thought and not that you have escaped a yoke. Are you such a one as was permitted to escape a yoke? There are some who threw away their ultimate worth when they threw away their servitude. Free from what? What is that to Zarathustra! But your eyes should announce to me brightly: free for what?
A central lesson of science is that to understand complex issues (or even simple ones), we must try to free our minds of dogma and to guarantee the freedom to publish, to contradict, and to experiment. Arguments from authority are unacceptable.
