Who thinks like this?

Andrew Ferguson on playwright David Mamet’s conversion from a Leftist to a Rightist:

“. . . Finley asked if he could send Mamet some books too. One of the first was A Conflict of Visions, by Thomas Sowell of the Hoover Institution. In it Sowell expands on the difference between the “constrained vision” of human nature—close to the tragic view that infuses Mamet’s greatest plays—and the “unconstrained vision” of man’s endless improvement that suffused Mamet’s politics and the politics of his profession and social class.

“He came back to me stunned. He said, ‘This is incredible!’ He said, ‘Who thinks like this? Who are these people?’ I said, ‘Republicans think like this.’ He said, ‘Amazing.’ ”
