Jonathan Rauch, author of The Constitution of Knowledge, discussing free speech with Andrew Sullivan:

Books like mine, I hope, and work like yours [Sullivan’s], will sound the alarm and show the way out, show that our arguments are strong, that pluralism is really the only path to a peaceful, productive and knowledgeable society. What the purists have to argue is only eternal warfare, in which arguments are not resolved. And the casualties are either physical human bodies, or ostracism, or ignorance, or chilling.

Even if we don’t win that argument right now, I keep pointing out to people: Remember the notions of free speech and free thought and all the rigors of science? These things are profoundly counterintuitive. The idea that speech is blasphemous, heretical, wrongheaded, offensive–add your adjectives–that speech is like that? That ideas like that should not only be allowed, but affirmatively protected, is the strangest and weirdest, and probably the craziest social idea that was ever invented. And it’s only rescued by the fact that it’s also the most successful social idea that was ever invented by a country mile. I would argue that it put an end to the creed wars. It gave us knowledge. It gave us finally some peace. And the result of that counter-intuitiveness is that you and I and our children, metaphorically, and our grandchildren and their grandchildren, will have to get up every morning and defend these ideas from scratch against a new generation that, for whatever new reason, emotional safety-ism or critical race theory or something else, that they don’t get it. And we just have to be cheerful about that because, historically speaking, we’ve done incredibly well for about two and a half centuries. This is a template in the history of the human species.
