“If it's knowledge and wisdom you want, then seek out the company of those who do real work for an honest purpose.”

As quoted in O₂ : Breathing New Life Into Faith (2008) by Richard Dahlstrom, Ch. 4 : Artisans of Hope: Stepping into God's Kingdom Story, p. 63; this source is disputed as it does not cite an original document for the quote. It is also used in <i> The White Rose </i> (1991) by Lillian Garrett-Groag, a monologue during Sophie's interrogation.

Context: The real damage is done by those millions who want to "survive." The honest men who just want to be left in peace. Those who don't want their little lives disturbed by anything bigger than themselves. Those with no sides and no causes. Those who won't take measure of their own strength, for fear of antagonizing their own weakness. Those who don't like to make waves — or enemies. Those for whom freedom, honor, truth, and principles are only literature. Those who live small, mate small, die small. It's the reductionist approach to life: if you keep it small, you'll keep it under control. If you don't make any noise, the bogeyman won't find you. But it's all an illusion, because they die too, those people who roll up their spirits into tiny little balls so as to be safe. Safe?! From what? Life is always on the edge of death; narrow streets lead to the same place as wide avenues, and a little candle burns itself out just like a flaming torch does. I choose my own way to burn.

Free speech in an age of identity politics (2015)
Context: To accept that certain things cannot be said is to accept that certain forms of power cannot be challenged.... This is why free speech is essential not simply to the practice of democracy, but to the aspirations of those groups who may have been failed by the formal democratic processes; to those whose voices may have been silenced by racism, for instance. The real value of free speech, in other words, is not to those who possess power, but to those who want to challenge them. And the real value of censorship is to those who do not wish their authority to be challenged. The right to ‘subject each others’ fundamental beliefs to criticism’ is the bedrock of an open, diverse society. Once we give up such a right in the name of ‘tolerance’ or ‘respect’, we constrain our ability to challenge those in power, and therefore to challenge injustice.
