Reason Online, the web component of Reason Magazine, has a report on the recent meeting of the World Future Society. A keynoter was Helen Fisher, the Rutgers anthropologist and author who scanned the brains of people in the throes of romantic love, and wrote about the results in her book "Why We Love."
Ronald Bailey, the author of the Reason article, reports,
Fisher declared, "We can no longer say that we live in a traditional marriage culture." Today, the form of modern American marriages can be increasingly described as companionate or peer marriage, or a marriage between equals. She ended by pointing to some positive trends in marriage."
He provides a very good precis of her other comments, well worth a read.
