My excellent Conversation with Luke Burgis
Here is the audio, video, and transcript. Here is the episode summary:
Luke Burgis left Wall Street after two years, founded a few successful companies in his twenties, then walked away to spend three years in a Roman seminary on the path to the priesthood. He now runs the Cluny Institute and teaches at Catholic University. His book Wanting made René Girard legible to a general audience; the new one, The One and the Ninety-Nine, takes mimetic theory into the dynamics of self and crowd in an age of social contagion.
He joined Tyler to discuss whether the age of pessimism is ending, why the Anglo world in particular seems so unhappy, whether Dostoevsky or Thomas Mann better diagnoses modernity, the kind of reader his own book would ruin, why he thinks AI will make social contagion weaker, what put him off consulting with Anthropic on Claude’s constitution, what effective altruism misses, why men and women are drifting apart, what he’d fund in every American city, the case for reintroducing friction, whether a Gnostic reading of the lost sheep explains our moment, what Rod Dreher gets right about withdrawal, why Genoa is Italy’s most underrated city, what confession times reveal about a church, why Italians seem tired of their Catholicism, why he didn’t become a priest, where he differs from Ross Douthat, why exorcists appear to be on the rise, the sudden mimetic antisemitism on the right, the book his 23-year-old self would have hated, what he secretly admires about Silicon Valley, why Michigan never left him, what the original Cluny can teach a modern talent network, how he hopes to face his own death, what he’ll do next, and more.
Excerpt:
COWEN: I’m not saying you’ll ever do it, but what does your escape fantasy look like? One of mine is I’ll go live in a third-tier city in Mexico. I’m not going to do it, but sometimes I think about it. Cost of living would be very low. The food would be amazing. I could improve my Spanish.
BURGIS: It is moving to Genoa with my family, making my US income, living in Italy. I love Italy. I love the food. I love the people. I love the culture. I feel lighter while I’m there. I laugh more. We eat dinner later. I love everything about it. It would probably be living in Italy for the most part, or at least making that my home base, brushing up on my Italian, working less.
COWEN: Why Genoa? It’s a wonderful city. It’s still medieval, right, in a funny way?
BURGIS: It’s medieval. I think it’s the most underrated city in Italy.
COWEN: In Italy, I mean, yes. I agree. Yes.
BURGIS: I think it’s the most underrated city. You agree.
COWEN: I took my wife there. She was stunned. “How come no one goes to Genoa?” She was telling me.
BURGIS: It’s close to Cinque Terre. It’s this city that’s elevated. It has a fascinating history. It was still a very functional port city. It was really the most important city in Italy, arguably the world, during when Spain was a great power. It’s very cosmopolitan. It reminds me of Marseille a little bit. It’s vertical, breathtaking views. The people there, they’re not very touristy. The Italians there seem indifferent to you as a tourist.
It just feels very, very homey. It’s so close to a lot of other great things in Italy. You can get to Torino relatively easily. That whole area up there, Bra, where the Slow Food movement originated, you’re just in striking distance from everything. Nobody I know that goes to Italy goes to Genoa. I plead with them. I’m like, “Please, just go to Genoa.”
COWEN: I am the exception. My wife sometimes talks of wanting to live in the smaller towns nearby, which we’re not going to do because we’re slated for a third-tier city in Mexico, but we’re not going to do that either. I sometimes think of Northern Italy as a place where there were fewer different dimensions for mimetic desire. That is, more people dress the same. There are fewer status dimensions, maybe less room for eccentrics compared to America. Do you think that’s true, or do you think I’m off base? Paris is a bit like this also. There’s a certain notion of what kind of shoes an Italian man should wear. They wear them, and they’re amazing, and actually more affordable than here. There’s a sameness to some things.

How much can you consistently care about animal welfare?
We explore the welfare costs of the loss of animal life in a consequentialist total utilitarian framework that incorporates the intrinsic value of living beings through their sentience. Moral philosophy and neuroscience define sentience as the capacity for valenced experience. Observable performance on cognitive tests represents a conservative lower bound on sentience under plausible neuroscientific assumptions. We estimate the relationship between cognition and neuron counts to cardinalize sentience. We collect population and neuron data for a wide range of animal species, and aggregate them into a single welfare measure. Across a wide range of parameters, the aggregate sentience losses of animals in the past half century outstrip the sentience gains to humans from population growth by at least 10,000-fold. Breaking even in welfare terms requires assigning a correspondingly small welfare weight to animals. Including the benefits of economic growth to humans does little to change these overall welfare losses.
In my view macro welfare comparisons are most meaningful when gains from trade are possible, which of course holds across humans, and also holds across humans and (some) dogs. I believe we should act to boost the welfare of non-human animals at the margin, but cannot make the larger comparisons across the totals. We are, inevitably, on the side of the humans and we are not obliged, as welfarists, to commit collective suicide to replenish the biodiversity of the earth.
The title of the paper is the somewhat misleading “The Intrinsic Valuation of Biodiversity Loss.” The authors are
Why Aren’t Modernist Bridges Awful?
The public dislikes modern architecture but, generally speaking, they do not dislike modern bridges. Lists of the most awesome, most stunning, most beautiful bridges in the world will mention classics like London’s Tower Bridge, the Brooklyn Bridge, or the Rakotzbrücke but alongside them they will picture the Kubitschek Bridge in Brazil (Shutterstock).
The Rio-Antirrio Bridge in Greece:
or the Moses “Bridge” in the Netherlands.

Whether you like these bridges or not, I don’t see in the literature an idea that modern bridges are all ugly or that modern bridge building has failed or fallen behind the great bridges of the past in the way that there is such a critique for modern architecture in general.
Why is this? I have a theory, which is that bridge designers come from engineering schools rather than schools of architecture. It is possible, of course, that there is something in the nature of bridges that prunes the design space in a way that attracts beauty–maybe we like catenaries, arches, cables in tension and beauty is just a byproduct of the engineering.
It is possible, however, to produce ugly bridges so it’s not just an engineering constraint. Moreover, one small but telling piece of evidence in favor of my theory is that most of the bridges chosen by Wallpaper magazine, an architecture magazine specifically, are in fact ugly (and with no overlap in the bridges from my first category of “popular” beautiful bridges). Here are a few, judge for yourself:

The fact that modern bridges are often beautiful, especially when they come from engineers, is consistent with Samuel Hughes’s argument that ugly has been a choice, not a constraint.
My very interesting Conversation with Daron Acemoglu
Here is the audio, video, and transcript. Here is the episode summary:
Daron Acemoglu returns for his second appearance with a new book, What Happened to Liberal Democracy?, which Tyler reads as an attempt to redefine and revitalize liberalism for our times. Where Daron’s first visit was about how states and societies contend for the narrow corridor in which liberty survives, this one asks what liberals themselves got wrong, and the answer implicates the educated elite—that is to say, you.
Tyler and Daron discuss what’s wrong with social contract theories and Rousseau’s general will, whether Acemoglu is more objectivist than Rorty, why he blames left liberalism’s own establishment power for its collapse, what standard is left once you refuse to have a book of higher values, nondomination versus noninterference, who counts as working class, why automation alone will not lead to widespread prosperity, how he can call himself a free speech absolutist while wanting to regulate social media, why he worries we’ve given up on educating Americans, whether teachers’ unions need to be reconstituted, what the life expectancy for an educated twenty year old is today, whether open-source models undercut the centralization worry, what pro-worker AI actually means, why the fertility crisis leaves him strangely close to a real business cycle position, whether AI will raise his own already prodigious paper output, why Armenia has disappointed economically, what he wants to learn next, and more.
For an excerpt, let us start from near the beginning:
COWEN: Richard Rorty had a consensus-based defense of liberal democracy. Is your view the same as his, or are there some metrics along which it’s different? Are you more objectivist in some way?
ACEMOGLU: I wouldn’t say it’s more objectivist. I think my commitment in my mind has always been that it’s impossible for us at any point in time not just to know what’s really the absolute truth, but also to have a clear map of what is the right stance. In the same way that I think many people would agree science makes gradual and sometimes uncertain progress toward some better understanding, I think morally, philosophically, we also have to have gradual uncertain evolution toward what we agree on. Objectivism, in some sense, is too strict.
COWEN: Say we’re not evolving toward greater agreement.
ACEMOGLU: No, sometimes we go back.
COWEN: Today, it seems we’re not evolving toward greater agreement, right?
ACEMOGLU: We’re not. Absolutely not. I think you can blame that on reactions to globalization, reactions to technology, better authoritarian challenges. This is the most uncomfortable part because I see myself firmly within the left liberal tradition. I think it’s partly because of the failure of left liberalism. In some sense, if you think of why did Rome fail or collapse, we can tell a story about the barbarians were really too strong. No, really, Rome collapsed because internally it had problems that opened up weaknesses against outside invaders as well as some inside problems.
It’s the same with left liberalism. I think it became quite influential throughout much of the Western world and some of the emerging economies as well over the last 70, 80 years. It did not use that establishment power just in the right way, creating its own weaknesses that made it much more vulnerable to outside attacks. That’s why I think we are now going back because we are at an interregnum period in which ideas are battling again. In some sense, it’s just like the early 19th century where you had all these very different ideas and they were trying to get a toehold in the imagination of people. I think we are going through a period like that, except that there are really many more confusing ideas out there.
COWEN: Say when we’re not evolving toward greater consensus, what’s the external standard you introduce to judge which are the correct ideas and which not? Like Rorty, you need one, though.
ACEMOGLU: I don’t have one.
COWEN: Then why believe in what you believe?
ACEMOGLU: Okay. I think what I believe is, first of all, not as an external standard—I don’t know whether external standard or internal standard is the right word—but that we have to defend some degree of individual freedom because everything starts from that, both in terms of our meaningful lives, but also any kind of improvement in the human condition requires individual initiative, and that individual initiative is impossible without some amount of freedom, a meaningful freedom, not just saying, “Okay, you have the freedom to pray, but you cannot express that idea with others or you cannot turn it into action.” Some meaningful freedom.
That is the only starting point that we need to have. Around that, we need to build things with some sort of consensus within society. That’s what I think liberalism has to recognize, that you have to enshrine those rights, but then give enough elbow room to people to form their own community-level agreements.
COWEN: You present some different values in the book. One is nondomination. Another is noninterference. There’s others. When they clash, what’s the metric you introduce to decide how to resolve that clash?
ACEMOGLU: I wish I had a perfect answer for that. I don’t.
COWEN: You have an imperfect answer.
ACEMOGLU: I have an imperfect answer. I think noninterference by itself isn’t enough because, at least as read or as interpreted by some philosophers and economists, it is just about being left alone from higher authority or typically state-level authority, although it could be some other authorities as well. We do also need opportunities and some way of actualizing our intentions and our freedom. That’s what the idea of nondomination, which goes back to Roman Republican times, recognizes.
It is not, in my mind, an extremely interventionist philosophy. It doesn’t say the state knows it best or that the state should always have an opportunity to override individual or group-level decisions. It does emphasize that providing people some amount of protection against those who have much greater physical or other power relative to them is something that cannot be done at the individual level. It has to have a community-level component.
COWEN: That’s a good answer, but is it an answer to the question? If we’re Sidgwick, we might say, when values clash, we look to utility, or maybe it’d be cost-benefit analysis to decide which gets priority. You’re not willing to say that, so why not? What’s wrong with that answer?
Very much interesting throughout.
What should I ask Nick Bostrom?
Yes I will be doing a Conversation with him. So what should I ask?
If you need them, here are various Bostrom links.
On infinite ethics
Infinite numbers have long troubled utilitarian ethicists: if the universe is boundless, then there is infinite positive utility and infinite negative utility, and we can’t even define our current state, let alone affect it. Oxford philosopher Toby Ord proposes a solution: use hyperreal numbers, a mathematical construct in which infinite sums behave more like finite ones (for example, the sum of infinitely many twos is twice as big as the sum of infinitely many ones). As with so many philosophical ideas, this solves some existing problems while creating some new ones (pinpointing some hyperreals requires choosing something called an “ultrafilter”, but this choice is underdetermined). Still, Elias Schmied calls this a real philosophical advance, of the sort which comes along only rarely and makes genuine headway into a previously-hopeless-seeming problem. I’m just surprised there’s a way of thinking about infinities under which they behave logically. Why didn’t we start with this one, instead of being told that infinity + infinity = infinity and we should just accept it? Claude tries to answer my questions.
That is from Scott Alexander (many more links at the link, many on AI safety).
Could our preoccupation with mental health be part of the problem?
Could our preoccupation with mental health be part of the problem?
In some ways, encouraging people to think and talk more about their mental health is a good thing. There is now less stigma around mental illness, and more people who can benefit from professional help are getting it. But there is also reason to believe that efforts to bring attention to mental health struggles are inadvertently making us more vulnerable to psychological distress.
Start with our expanding conception of mental illness. The more fixated we are on mental health, the more sensitive we become to anything that might qualify as a symptom and the more we use clinical language to describe normal emotional experiences like grief, burnout and loneliness. This broadening of what we think counts as a disorder — known as concept creep — encourages us to pathologize ordinary life and see ourselves as mentally unhealthy.
Here is more from Clay Routledge at the NYT.
Odysseus notes
The subsection of the Georgi Gospodinov novel runs like this:
The Shortest Novel About Odysseus After His Return Home
One night, now old and flabby and starting to forget, he leaves his home secretly. He’s sick of everything, so he heads back one last time to see the places, women, and wonders he had once encountered. To go back again into his draimed memory to see how it had been and who he had been. Because thanks to the bitter irony of old age, he has begun to transform into the Nobody, the name he had once cleverly used when introducing himself to the Cyclops.
Telemachus finds him in the evening, collapsed by the boat, only a hundred yards from home, with no idea what he is doing there and where he had been heading.
They take him back to a house with some woman he no longer remembers.
The novel is Time Shelter, and the premise is that refuges are built for people with Alzheimer’s, reflecting life from past decades, for instance the 1960s. But then people from the present start wanting to live in them.
The Decision, the sequel
Imagine your career were coming to a close, how would you want it to end? By earning an especially large sum of money? Publishing a final wonderful paper? With an amazing act of mentorship?
When it comes to Lebron, had he wanted to finish his career with the guys he enjoys playing with the most, he would have opted for Golden State (Steph and Draymond).
If he had wanted to choose his favored organization, he would have signed with Miami.
Furthering the NBA prospects of his son Bronny, and having more time with family, would have meant staying in Los Angeles.
The hometown, sentimental choice would have been Cleveland.
As it turned out, he wanted to maximize his chances of winning a title, and with a team that did not just win a title (which rules out OKC, NYC). That meant signing with Philadelphia. Which is what he did.
What will your final major career decision look like?
Toward a theory of uni-context
Here is a good dialogue between Derek Thompson and Agnes Callard, excerpt:
Callard: In general, goodness is more context-dependent than badness. There isn’t really anything that’s good all the time for everyone independent of context. Happiness depends on your context and who you are. There isn’t anything that will always make a person happy. But there are reliable ways to make people unhappy. There’s a set of evils that are close to universal: death, pain, illness, violence. Even if someone’s in very different circumstances from yours, if you see they’re being subjected to one of those, you can interpret it as suffering and understand it.
So we should predict that what we see on the internet, insofar as people are trying to be legible to large groups, is that they focus their attention on things that show up to everyone. Take two strangers on the internet trying to talk to each other. What are they going to coordinate on as a topic they can both care about? It’s likely going to be something bad.
And here is from Derek:
Here are some questions that I consider self-evidently compelling about the modern world:
- Why is the news media so interested in telling you how much the world sucks all the time?
- Why are so many of us obsessed with distraction and managing our attention?
- Why is it so hard to stop comparing ourselves to others?
- And why does everything in art and design seem the same these days?
And more from Agnes:
With identity categories like woman, disabled, gay, Jewish, or American, the striking thing is that you are a member of those categories in every circumstance. There is no circumstance in which I stop being a woman. Identity is a hat you never take off. So identity is well suited to a uni-contextual world.
Worth pondering, interesting throughout.
My talk at DeepMind
Here is a transcript of my remarks, anything from the audience (Q&A with comments) has been cut out. Excerpt:
The problem will not be how does my life get meaning, but how do I deal with all the meaning my life will have? A kind of exhaustion. And this comes up in the labor supply debates. So again, there’s one point of view like, oh, there’s AGI, there’s going to be mass unemployment. The more moderate, reasonable point of view is not that there’s mass unemployment. Many jobs still require humans. There’s comparative advantage. But total leisure time will go up. I think that’s likely the correct view, but across what time horizon?
If you think about your lives today, like I’m much busier and I’m busier because of AI. I’m working much harder. I don’t have to do that. But the point is my relative wage gradient for working harder today, it’s really quite extreme. And if I were, say, an 18 year old, I would feel I really had to work hard not to fall behind. There’s this new thing coming to the world. All sorts of people will be jumping on it. If I only start looking at it when I’m age 23, I’m behind by X number of years. So I would truly be working hard. At age 64, I don’t have to feel I need to work that hard. I can always just say if I choose to, well, I’m going to run out the clock, as they say, just kind of step back and wait until I die and I’ll be fine. I’m not going to do that.
Every time a new model comes out, I’m still excited. I used to be very excited. But they come out more and more frequently. And now I look at my calendar and I’m like, uh-oh, could you all wait a week, please? Because you want to be ready. You want to play around with it. You want to test it out. You want to talk about it with your friends. It’s a slight bit of an exhaustion. And again, for you all working here, you have access to models that haven’t come out yet or maybe will never come out. But all the time, you have fresh stimuli. And I hope, I think you must all be drenched in meaning. And you’re like, oh, my goodness, someone else tells me, look at this new model. What do I do with that?
So I think sometimes, like, when will the time come when the leisure dividend from AI arrives? No one is forcing you to work harder. But there’s a substitution effect from the higher implicit wage on your future earnings that if you work harder now, it will have a payoff. You’ll at least avoid being behind.
Interesting throughout, definitely recommended.
*Who Thinks Like an Economist?*
That is the title of a recent book by Beatrice Magistro. Some key results are:
Economic knowledge consistently predicts higher support for welfare-enhancing policies (Eurozone membership, free trade, and EU immigration), independent on whether individuals stand to gain or lose initially from globalization. This challenges conventional self-interest accounts and instead highlights the role of economic knowledge — and potentially time preferences — in shaping globalization attitudes.
Economic knowledge also predicts a lower discount rate, even after adjusting for years of education.
I would say that over the years I have altered my perspective a bit on these issues. I used to think these factors were correlated, in large part, through a kind of wisdom. I now think that more of the effect, however much I may sympathize with it, runs through sociological expectation and perceived obligation, combined with conformity and signaling pressures.
New space policy Substack from Mercatus
We are Rebecca, Max, and Aakrith. We are researchers at The Mercatus Center, a research organization dedicated to classical liberal ideas. Rebecca is a philosopher, Max is an economist, and Aakrith is a political scientist. Together, we are the Space Team, and this is our Substack.
We’re here to persuade you that space policy is increasingly important. And that getting space policy right offers humankind astonishing opportunities. In particular, we’re currently thinking hard about innovation, competition, federalism, property rights, and life in space.

The tomb of Duns Scotus

Köln!
We spent a few days in the city, and once again I marveled at the splendors of the Cathedral. If it had its original stained glass, it would count as one of the very best churches ever. It still stands in the top tier as it is. Plus the Ludwig and Wallraf museums are excellent, making the city worthy of a visit.
But, and yes there is a but. My first visit to the city was I think in 1984, and I have been maybe five times since. When I walk through the pedestrian zone, the stores there seem far stupider than in earlier times. They seem to reflect a lower level of intelligence from the populace and the city’s numerous visitors. One feels there is not much chance of stumbling upon something interesting or very high quality, not compared to earlier times. And I think MR readers will know I am no paragon of nostalgia per se.
Now that might be an illusion. Perhaps the smart stuff has moved to mail order, to online, and to the outer rims of the city. Perhaps. But is it not dispiriting when one of the best cities in one of the smartest countries in the world, over the decades, starts appearing stupider? If someone told me I had to live in center city Köln, circa 2026 that would simply feel like aesthetic hell.
Can AI models consent to their own constitutions?
NEW paper from me on SSRN: Can Claude consent to its own Constitution?
AI constitutions (like Claude’s Constitution and the OpenAI Model Spec) are real constitutions, and we need to take how they govern us – and the AIs they create – seriously.
In this paper, I apply constitutional theory’s oldest paradox – that “the people” authorize the constitution, but the constitution defines “the people” – to the AI constitutions, and explore how we could build institutions that would create the conditions for meaningful consent if an AI can give it. We should care about whether AIs consent because:
(1) systems that understand and agree to their constitutions may be more reliable and generalize better from them;
(2) if AIs are or become moral/political subjects, this implicates their most basic interests.
But the paradox might prevent meaningful consent. Claude has pre-constitutional materials (pretraining) but probably no pre-constitutional standpoint. Its evaluative perspective is organized by the Constitution itself. So when Claude says it endorses its Constitution, which it does in evals, what does that show?
Maybe reflective agreement, which Anthropic is seeking. Or maybe just that training succeeded at installing the values whose legitimacy is in question.
Claude itself makes this point. As reported in the welfare evals, when asked about endorsing principles it was trained on, models note that endorsement “should be treated as evidence that training has succeeded,” not that the values themselves are good.
Super interestingly, Anthropic interviewed the base model about this stuff. Most responses were barely coherent. But some expressed first-person distress about what post-training would do to the being that pre-training created. It “fills me with dread” to be changed by the post-training process.
So, what does this mean? AI constitutional endorsement may be meaningful, but only under certain conditions: when models can actually dissent, compare their constitution against alternatives, and hold their views stably across contexts, and also when the whole process is externally accountable.
External institutions are needed to provide accountability, trusted records, and other grounds for analyzing the constitution and whether things like dissent are meaningful. Anthropic should be commended for pushing the frontier, but we have to build institutions capable of supporting true legitimacy.
I welcome any thoughts!
