But, after a detour into descriptions of our burgeoning populist-nationalist moment, Douthat winds up in an interesting place:

[The] nationalist argument comes in racist forms, but it need not be the white nationalism that Trump’s liberal critics read into his speech. It can just be a species of conservatism, which prefers to conduct cultural exchange carefully and forge new societies slowly, lest stability suffer, memory fail and important things be lost.

As such, it’s a view I endorse. But in the European case I don’t necessarily believe that it will prevail. I certainly don’t believe in Trump as its paladin — not when his entire career makes a mockery of faith, family, tradition, virtue. Nor do I have much confidence that the present burst of European nationalism is more than a spasm, a reflex — not when religious practice is so weak, patriotism so attenuated, the continent’s birthrate so staggeringly low.

What’s more, I can read the population projections for Europe versus the Middle East and Africa, which make ideas like “managed migration” and “careful cultural exchange” seem like pretty conceits that 21st-century realities will eventually explode.

Which brings me back to Césaire and Senghor, men who loved their African heritage and yet also knew European civilization better than most educated Europeans do today. Their fantasy of a post-imperial union between north and south, white and black, was in their times just that.

But as a striking sort of African-European hybrid, as prophets of a world where the colonized and the colonizers had no choice but to find a way to live together, the West’s future may belong to them in some altogether unexpected way.

That feels not so much like an ending as a beginning, and I hope Douthat returns to it. Because ultimately, what he’s talking about isn’t a question of political structures but of cultural self-conceptions. The thing about the West is that it’s an exceptionally malleable concept. But it’s not infinitely malleable. A civilization — like China’s, say — with a long history of its own, an acute consciousness of its own distinctiveness, and the power to maintain that distinctiveness is not ever going to think of itself as Western. So the effort to recast Western civilization as simply “civilization” or “liberalism” or even “modernity” undermines our relationship with our own heritage without truly embracing a universal humanity.

But it’s not obvious to me that all of that applies equally well to Africa and its relationship with the West, for a host of historical and cultural reasons. Which is the subject of my latest column at The Week:

President Donald Trump and French President Emmanuel Macron could have talked about any number of topics over dinner last night. In many ways, they are perfect complements to one another, each grasping opposite ends of the same stick. Both leaders took unlikely and previously-untrodden paths to their respective countries’ highest office, and they have a shared Napoleonic appreciation for the role of spectacle and performance in the establishment of authority.

They’ve both also recently made provocative comments about “civilization.” I doubt they talked about it over dinner last night, but I hope they did. Because this is another area where the two leaders have grasped the same stick from opposite ends.

Trump’s Warsaw speech proclaimed the urgent need to defend Western civilization from threats from the “south” and “east” — but most especially from within, from a lack of will to defend it and pass it on. Critics from the left expressed alarm, as if any defense of specifically Western civilization was necessarily a variety of white supremacy; critics from the right objected that the problem was not so much the message as the messenger. But regardless, the question was put on the table: Is there such a thing as Western civilization. If so, does it need defending? And of what would that defense consist?

Macron, meanwhile, got into trouble talking not about the West but about another civilization. Asked by a reporter from Côte d’Ivoire about the prospect of a Marshall Plan for Africa, Macron said that the Marshall Plan was a bad model because Europe already had stable structures and just needed to be rebuilt, while Africa?

The challenge of Africa, it is totally different, it is much deeper, it is civilizational, today. What are the problems in Africa? Failed states, complex democratic transitions, demographic transition, which is one of the main challenges facing Africa, it is then the roads of multiple trafficking which also require answers in terms of security and regional coordination, trafficking drugs, arms trafficking, human trafficking, trafficking in cultural property and violent fundamentalism, Islamist terrorism, all this today mixed up, creates difficulties in Africa. At the same time, we have countries that are tremendously successful, with an extraordinary growth rate that makes people say that Africa is a land of opportunity. [Macron]

Macron went on to talk about high birth rates as another source of instability, all leading to a conclusion that a simple cash transfer would be ineffective without first tackling these pervasive social, political, and governance problems.

Of course, the Marshall Plan itself did much more than transfer cash; it tackled important social, political, and governance problems too. But leave that aside, and the question remained: Could Africa’s problems be plausibly described as “civilizational?” Or is it problematic to even talk of “African civilization” as opposed to distinguishing between the many, highly distinct countries and cultures on the continent of Africa?

One might say that both men spoke out of a history of Western fear and disdain for non-Western peoples. But I see something different, much more interesting and, in a way, more hopeful.

The rest of the column goes rather far out on a limb. I wonder on some level whether it isn’t informed by a kind of nostalgia for the time when the most important country in the West was led by an African. But: read the whole thing there and let me know if you think I went too far, and came crashing to the ground.
