A growing present danger, a time of dark intent, is creeping steadily toward us in world politics.
A long era of mostly right-vs.-left ideological conflict is giving way to a new era — a new age of tribalism on a global scale.
Stepping back, looking at history, it's clear that it was the industrial revolution that manufactured the familiar ideological politics of right and left. For 250 years, the great divisive controversy has been over the role of the state vis-à-vis capitalist economic production. A compromise was reached after the late-20th-century collapse of communism — it consisted of a free-market welfare state featuring expansive public services and some redistribution of wealth, while imposing regulation on the excesses brought about by the competitive pursuit of self-interested profit.
But now we have moved beyond the industrial age into the postindustrial age under conditions of globalization. It is not surprising that our politics are changing in fundamental ways.
People everywhere are moving up Maslow's famous "hierarchy of needs." Around the world, people increasingly take basic material sufficiency for granted. They therefore seek more of the self-actualizing goals of life. This leads to the "politics of identity" and so to a new tribalism in the affairs of nations.
For most of history, humanity has structured itself into tribes, whose members mistrust "others," are parochial in their values and place little value on cosmopolitan sophistication in thinking.
Where tribalism prevails, goodwill and innovative ideas are scarce.
Of course, ideology, no less than tribalism, can lead to intolerance, violence and extreme, wrongheaded thinking. In fact, the trouble when ideologies become fundamentalist is that they take on the vindictive character of tribalisms.
