This is a remarkable day in the history of our country. We have never over our centuries inaugurated a man like Donald Trump as president of the United States. You can select any random group of former presidents — Madison, Lincoln, Hoover, Carter — and none of them are like Trump.

We’ve never had a major national leader as professionally unprepared, intellectually ill informed, morally compromised and temperamentally unfit as the man taking the oath on Friday. So let’s not lessen the shock factor that should reverberate across this extraordinary moment.

It took a lot to get us here. It took a once-in-a-century societal challenge — the stresses and strains brought by the global information age — and it took a political system that was too detached and sclerotic to understand and deal with them.

There are many ways to capture this massive failure, but I’d rely on the old sociological distinction between gemeinschaft and gesellschaft. All across the world, we have masses of voters who live in a world of gemeinschaft: where relationships are personal, organic and fused by particular affections. These people define their loyalty to community, faith and nation in personal, in-the-gut sort of ways.
