Professionals give advice; pilgrims share wisdom.

In uniform patriotism can salute one flag only, embrace but the first circle of life - one's own land and tribe. In war that is necessary, in peace it is not enough.

Sharing is the essence of teaching. It is, I have come to believe, the essence of civilization...Without it, the imagination is but the echo of the self, trapped in a soundproof chamber, reverberating upon itself until it is spent in exhaustion or futility.

I take "We, the People" seriously because I don't know how we build a civilization without reciprocity.

Presidents are afraid to lose wars. They're afraid to be outflanked on the right by the militarists. They don't want to be seen as soft on either communism or soft on terrorism or whatever. So presidents are constantly tugged away from their domestic commitments to foreign policy.

The struggle of ordinary people for a decent living, for security, is as old as the republic, but it's taken on a new and urgent edge. Instead of shared prosperity our political system has now produced a winner-take-all economy.

I've always thought the American eagle needed a left wing and a right wing. The right wing would see to it that economic interests had their legitimate concerns addressed. The left wing would see to it that ordinary people were included in the bargain. Both would keep the great bird on course. But with two right wings or two left wings, it's no longer an eagle and it's going to crash.
