I have always thought that all men should be free; but if any should be slaves, it should be first those who desire for themselves, and secondly those who desire it for others. Whenever I hear anyone arguing for slavery, I feel a strong impulse to see it tried on him personally.
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?
Don't think in terms of comfort; think in terms of freedom. Don't think in terms of safety, think in terms of being more alive. And the only way to be more alive is to live dangerously, is to risk, is to go on an adventure. And the greatest adventure is not going to the moon - the greatest adventure is going to your own innermost core.
Only by obedience to his genius; only by the freest activity in the way constitutional to him, does an angel seem to arise beforea man, and lead him by the hand out of all the wards of the prison.
