Here's an interesting piece on cultural fragmentation from Jeffrey Brown, who anchors the PBS News Hour. Back in the pre-Web era, I recall watching that show, back when it was McNeil-Lehrer, for it did good long-form reporting and discussion on issues that went beyond the headlines and the quick observation. Since then, I tend to not watch much TV news unless there is a major breaking item that doesn't lend itself to the Web.
Brown discusses the more combative nature of modern political discourse, closing with this imagry-
To make that point, he quoted from an interview with Israeli novelist David Grossman, whom Brown said tries to keep a focus on basic human problems in a place where it is all to easy to be overwhelmed by political issues and security problems.
"We are now in danger of becoming like a suit of armor, but without the knight inside," Brown recalled Grossman saying.
The more we feel under attack, the more we retreat to a siege mentality. We spend a lot of our energy defending against attacks and less on doing productive and constructive things.
The Armor of God doesn't restrict one from moving forward with life; the rhetroical armor we put up can do so, expecially if we go to confrontation mode as a matter of course.
