Unfortunately, pragmatism is not always good politics. The greatest asset of mid-20th century social democracy—its willingness to compromise its own core beliefs in the name of balance, tolerance, fairness and freedom—now looks more like weakness: a loss of nerve in the face of changed circumstances. We find it hard to look past those compromises to recall the qualities that informed progressive thought in the first place: what the early 20th century syndicalist Edouard Berth termed “a revolt of the spirit against . . . a world in which man was threatened by a monstrous moral and metaphysical materialism”.

We don’t live in a world of fixed historical laws that says the—as you describe it—liberal state was born at a particular time, lived and died, and that’s what we’re stuck with. But there are reasons why some things are much harder to retain, to invent, to reinvent than others.

My concern tonight is the following: Why is it that here in the United States we have such difficulty even imagining a different sort of society from the one whose dysfunctions and inequalities trouble us so? We appear to have lost the capacity to question the present, much less offer alternatives to it. Why is it so beyond us to conceive of a different set of arrangements to our common advantage?
