The expected value of longtermism

(for 3 Quarks Daily)

I’m not sold on longtermism myself, but its proponents sure have my sympathy for the eagerness with which its opponents mine their arguments for repugnant conclusions. The basic idea, that we ought to do more for the benefit of future lives than we are doing now, is often seen as either ridiculous or dangerous.

Usually, this takes the form of thought-experiments in which longtermists are supposed to accept major harm to humanity now in the hope of some huge potential benefit later. Physicist and YouTuber Sabine Hossenfelder, after boasting that she couldn’t be bothered to read William MacAskill’s book What We Owe the Future (“because if the future thinks I owe it, I’ll wait until it sends an invoice”), goes on to interpret a paper by MacAskill and his colleague Hilary Greaves in this way: “a few million deaths are acceptable, so long as we don’t go extinct.” Phil Torres takes aim at an updated version of the same paper, in which Greaves and MacAskill argue that possible futures with huge numbers of people, even if they are unlikely, represent an expected value that outweighs that of the near future. He reads it as implying that MacAskill and Greaves might well press a button that lets 1 million people die now, to increase the chance that 100 trillion people will be born later.

Liberalism in the 21st century

(for 3 Quarks Daily)

Francis Fukuyama does not mind having to play defense. Recognizing that the problems plaguing liberal societies result in no small part from the flaws and weaknesses of liberalism itself, he argues in Liberalism and its Discontents (Profile Books: 2022) that the response to these problems, all said and done, is liberalism. This requires some courage: three decades ago, Fukuyama may have captured the spirit of the age, but the spirit has grown impatient with liberalism as of late. Fukuyama, however, does not think of it as a worn-out ideal. He has taken note of right-wing assaults, as well as progressive criticisms that suggest a need to go beyond it; and his verdict is that any attempt at improvement will either stay in a liberal orbit or lead to political decay. Liberalism is still the best we have got.

How many philosophers does it take to write a dialogue?

(for 3 Quarks Daily)

“The constant direct mode of address was a chore. No one will enjoy having this read to them.” Quoting from a referee report on the Nicomachean Ethics misses the point of James Warren’s hilarious rejection letter, but I looked it up because I remember thinking that the fictional critic was onto something, and not just about Aristotle. “I had the impression at times that some kind of conversational or dialectical background was being assumed but this is not at all marked in the text.” Indeed! Why hide the fun part?

I owe several very happy moments to well-executed philosophical dialogues: Imre Lakatos’ Proofs and Refutations, Larry Laudan’s Science and Relativism, and Aristotle’s former supervisor come to mind. I will be ever so grateful to anybody who can point me to similarly exciting conversations. The dialogue form draws and holds the attention: it can let worldviews clash in the abstract, but it can simultaneously delve into matters of detail without becoming boring – these details having been established, after all, to flow not just from the idiosyncratic preoccupations of one contingent mind, but from larger intellectual interests common to at least two separate perspectives.

Erasmus In The 21st Century

He had a visceral aversion to war, was strongly in favor of social distancing in times of pandemic, and believed it would be a good thing if the Germans turned down their heaters a notch or two. Of these still sympathetic opinions, the last was admittedly informed by his discomfort with wood stoves. Erasmus did comment on fuel markets once: echoing a friend’s joke, he claimed to be annoyed by heretics for being burned at such a scale that it drove up wood prices.

It was one of the many occasions in which he spoke with dry irony about things that disturbed him deeply. Erasmus found his own way of talking about violence and war, and the other horrors that humans inflict upon each other. At the deepest level, his analysis was that war is bad. He was not, confirms his biographer Sandra Langereis, a very strong political thinker. An individualist rather than a sociologist, he tended to see war as a moral evil, and blame it on the foolishness and wrongheadedness of rulers. The people found cities; the mighty raze them to the ground.

Perhaps this is a good time to read Erasmus.

Beyond our needs: on spatial analogies for death

(for 3 Quarks Daily)

“Everyone feels it’s an unbearable thought, to be limited in time, – but what if you were spatially unlimited, would that not be […] as desolate as immortality? By Zeus, no one is ever depressed because they do not physically coincide with the universe, I at least have never heard a philosopher or poet about it”

I was reminded of this thought, expressed by a character in a novella by the Dutch writer Harry Mulisch, when I read Tim Sommers’s reflections about death here on 3QuarksDaily. Sommers suggests a similar symmetry between time and space: building on the idea that we can think of ourselves as four-dimensional creatures, he wonders why we should care more about being temporally limited than about being spatially limited.

Sommers presents his case, not as a clinching argument that demonstrates that death ought to be nothing to us, but as a therapeutic move that could make it lose some of its sting, changing our perspective on it by showing it to be like something we already accept. I think that is a fair strategy, although in the end I find neither Mulisch’s (character’s) nor Sommers’s version of this symmetry argument convincing.

Where Shall Wisdom Be Found?

(for 3 Quarks Daily)

In one of the opening scenes of The Chair (2021), we are treated to an ideal-typical self-diagnosis of a struggling English department. Its new chair, Ji-Yoon Kim, narrates:

I’m not gonna sugarcoat this: we are in dire crisis. Enrollments are down more than 30 percent, our budget is being gutted. It feels like the sea is washing the ground out from under our feet. But in these unprecedented times, we have to prove that what we do in the classroom – modeling critical thinking, stressing the value of empathy – is more important than ever, and has value to the public good. It’s true, we can’t teach our students coding or engineering. What we teach them cannot be quantified, or put down on a resumé as a skill. But let us have pride in what we can offer future generations. We need to remind these young people that knowledge doesn’t just come from spreadsheets or Wiki entries. Hey, I was thinking this morning about our tech-addled culture and how our students are hyperconnected 24 hours a day, and I was reminded of something Harold Bloom wrote. He said: ‘Information is endlessly available to us. Where shall wisdom be found?’

Giambattista Vico Enters The Classroom

(for 3 Quarks Daily)

It’s my favorite topic of the year, I tell the kids, before scanning my conscience for signs that I have just lied to them. No, this feels about right, and in any case, they didn’t need my reassurance: after a dry unit about ratios, at my mention of the word “probability” I can practically hear the sound of neurons firing. Whether they know of any contexts in which chance turns up? Boy, do they. My twelve-year old students inform me about dice, cards, spinners, lotteries, casinos, about your chances of survival in Squid Game, about unearthing rare minerals in Minecraft, and about whether the stuff you want to buy is actually in stock because sometimes they run out and there’s no telling in advance when. Also the weather.

I love introducing them to the math of probability precisely because it is a topic that they have already thought about so much, but that I know many of them have incoherent intuitions about. Not that I don’t, of course, but I am a little bit ahead of them and I know from experience what I am working with. Somebody will opine that the chance that it’s going to rain next month is “fifty-fifty” because it either will or it won’t. Somebody will say that there is a 1/7 chance that someone’s favorite day of the week is Thursday. Somebody will reason that since the highest sum you can roll with two D6-dice is a 12, the chance you roll a 10 is 1 in 12, which…

Oh wait, is it? Anyway, you get the point: the process feels properly Socratic, taking slightly muddled concepts that students already feel strongly about, and providing the right nudges to make them reconsider some of those concepts and make others click together. It is a significant source of satisfaction every year to see just how fast ‘the group’ moves from guessing that a sequence of three coin flips has six possible outcomes (unless it can land on its side, which they also unerringly point out), to calculating the number of four-digit pin codes where all the digits have to be different.

On Feeling Small: Reading John of Salisbury’s Metalogicon

(for 3 Quarks Daily)

“I am by nature too dull to comprehend the subtleties of the ancients; I cannot rely on my memory to retain for long what I have learned; and my style betrays its own lack of polish.” Among the benefits that reading the twelfth-century philosopher John of Salisbury’s Metalogicon has brought me were the pleasure of finding a witty and humane voice to introduce me to the new and faraway world of 12th-century learning (of which voice I intend to give plenty of examples below), and the fact that he helped me quit Twitter (again, more to follow). Apart from those, however, a major one was certainly the consolation of seeing an unquestionably capable thinker express his intellectual limitations in terms that seem genuine, going further than what perfunctory modesty would have required.

There have surely been thinkers who were more emphatic about their natural flaws, but there is a fine line between the comforting and the disturbing. When the 20th-century Dutch philosopher Leo Polak dreaded his approaching inaugural address, he wrote in his diary: “I came to nothing […] I have been of no value, for my family or for other people, or even simply done my duty. My pathological lack of memory my only excuse, but it is also partly laziness and sloppiness (no card system) and having whiled away my time, having flattered myself with undeserved success.” That, too, resonates, but not in the uplifting way that John’s confessions do.

Angry Atheists

(for 3 Quarks Daily)

“Why, during the seventeenth century, did people who knew all the arguments that there is a God stop finding God’s reality intuitively obvious?” This, says Alec Ryrie in his Unbelievers: An Emotional History of Doubt (2019), is the heart of the question of early modern unbelief (136).

Ryrie’s point is that arguments pro or contra theism, and the influence of philosophical and scientific developments upon these arguments, are not actually crucial to the possibility of unbelief. The currents that run underneath these arguments are instinctive, emotional, and these are what we should look at if we want to understand doubt and denial of Christian theism historically. The history of unbelief is not primarily the history of eighteenth-century Enlightenment radicals and nineteenth-century science warriors, but of premodern anger and anxiety.

“A good way of knowing things”: Eric Hayot’s defense of the humanities

(for 3 Quarks Daily)

Unfortunately, it is always worth your time to read a book in praise of the humanities. Given the unenviable position of the humanities in public education and in contemporary cultural and (especially) political discourse about valuable expertise, any author that comes to their defense has to find a strategy to shift the narrative, and will thereby almost invariably do something interesting.

They move our focus from economic value to democracy and citizenship, for example. Or they argue that there is not actually a mismatch between the skills provided by a well-balanced liberal arts curriculum and the demands of technocapitalism, or that the humanities themselves produce the same kinds of intellectual goods as the natural sciences with which they tend to be contrasted.
