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.
... how have I used rivers, how have I used wars
to escape writing of the worst thing of all--
not the crimes of other, not even our own death,
but the failure to want our freedom passionately enough
so that blighted elms, sick rivers, massacres would seem
mere emblems of that desecration of ourselves?
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?
As a nation, we began by declaring that 'all men are created equal.' We now practically read it 'all men are created equal, except negroes.' When the Know-Nothings get control, it will read 'all men are created equal, except negroes, and foreigners, and Catholics.' When it comes to this I should prefer emigrating to some country where they make no pretense of loving liberty – to Russia, for instance, where despotism can be taken pure, and without the base alloy of hypocrisy.
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.
Is our day of creative life finished? Does there remain to us only the strange, awful afterwards of the knowledge in dissolution,the African knowledge, but different for us, who are blond and blue-eyed from the north?.... There was another way, the way of freedom. There was the paradisal entry into pure, single beingwhich accepted the obligation of the permanent connection with others, and with the other, submits to the yoke and leash of love, but never forfeits its own proud individual singleness, even while it loves and yields.
