Being on the frontier, as I've said, required doing rather than imagining: clearing land, building shelter, obtaining food supplies. Frontiers test ideologies like nothing else. There is no time for the theoretical. That, ultimately, is why America has not been friendly to communism, fascism, or other, more benign forms of utopianism. Idealized concepts have rarely taken firm root in America, and so intellectuals have had to look to Europe for inspiration. People here are too busy making money - an extension, of course, of the frontier ethos, with its emphasis on practical initiative.
