Good piece -- here is an excerpt.
"The true significance of Scott Alexander is less in what he writes, than in his whole approach to writing—and not (or at least not only) because Alexander has a particular gift, but because he has chosen to wield that gift in furtherance of Truth. To notice the specifically weird things Alexander or other Rationalists sometimes say is to miss the underlying message that in their company, the Overton window is open. Speech is free. Respectful, authentic pursuit of the truth is permitted no matter where it leads, and no one will be punished for being wrong. Bad thinking will be corrected, if possible, not with ridicule or other rhetorical pressure to conform, but with good thinking. Rationalists, in short, are a group of people who picked up the liberal, academic, philosophical traditions of Western civilization when institutions like the New York Times decided to abandon them."
