Daniel P. Goldman writing in First Things:
“Why do men chase women?” asks Rose Castorini in Moonstruck. “Because they want to live forever.” The data suggest that we marry and have children for just that reason. When we cease to hope in eternal life, we no longer marry and no longer have children. That is the terrible lesson that the triumph of secularism has taught us. In industrial countries where atheism triumphed in the form of communism, fertility rates have fallen to levels barely half of replacement. The fertility of Eastern Europe in 2005 was only 1.25 children per woman, according to the United Nations Population Prospects. Japan stood at 1.3. In secular Western Europe it was 1.6. In industrial countries where most people profess some form of religious faith, however, fertility remains at replacement levels or above. America’s fertility in 2005 stood at 2.1, and Israel’s at 2.9.
