God in Set Theory

I have 3 younger brothers, and when one of us has a “round” birthday, we all get together with our families to celebrate. What we do mostly is talk. (There used to be a great deal of drinking involved, but now it’s mostly just talk.) Many years ago we gathered in Philadelphia to celebrate Rudy’s 50th. My brother Gaylord was teaching Linguistics and Russian at the time, so he and I had some interesting discussions about the areas of overlap between linguistics and my fields of Set Theory and Mathematical Logic, e.g. context free grammars, Turing machines, etc.

Gaylord and I had just returned to the church after having turned our backs on God for 30 years or so. While I returned to the faith of my childhood and landed at First Pres, Gaylord somehow ended up with the Anglicans. So it was that on the Sunday of that weekend in 1995 we went to Christ Episcopal Church, spiritual home to many of our country’s founding fathers. The gospel that morning was the parable you know as the Parable of the Prodigal Son, which we first-borns call the Parable of the Unappreciated Elder Brother.

As I sat there listening again to the story of how the younger, irresponsible sibling inveigles his “inheritance” from his father, then blows it all on booze and broads, only to be welcomed home like a prince, while the responsible older sibling gets nothing more than an attaboy and an invitation to the party in honor of his wastrel brother, I could feel my forehead furrowing with puzzlement and displeasure. It just wasn’t fair!

Then a remarkable association occurred. Probably because of my conversations with my brother, I recalled gazing at a room full of such furrowed foreheads, almost 30 years earlier. I was teaching a class on logic and set theory in a summer program for high school teachers at RPI. I had just received my Masters degree and my professor, who was scheduled to teach the class, got a research grant at the last minute and asked me to sub for him.

Now, set theory starts out innocently enough. A set is any well-defined collection of objects, like you, me, and the square root of 3, although mathematicians of course focus on sets of mathematical objects, like the set A containing the integers 1, 3, 5, and 7, written
A = {1,3,5,7}
and the set B containing the integers 2, 3, 4, 5, and 6, written
B = {2,3,4,5,6}

I introduced to the class the concepts of the union of two sets – the set containing all members that are in one or the other of the two:
A U B = {1,2,3,4,5,6,7}
and the intersection of two sets – the set containing just those members that are in both of them:
A ∩ B = {3,5}

The classroom was all smiles. These folks were mostly in Troy for the month with their families, and they were thinking, “beach – I think we’ll go to the beach this afternoon.”

We discussed the concept of the cardinality or size of a set, and the related question of determining if two sets are the same size. For sets like A and B above, this is easy: we count one; then we count the other; then compare counts. In our case, A has four members, B has 5, so B is larger than A. Smiles still reigned.

But the really interesting sets, like the set N of all positive integers, or the set Q of all rational numbers (proper or improper fractions of integers) have more than a finite number of members. If we had to count their members to compare them, we could never finish counting the first one, we could never even begin counting the second one, and we would never get an answer. So mathematicians found another way to compare the sizes of two sets We say that two sets are the same size if there is a correspondence between each member of one with a unique member of the other and vice versa. In the case of A and B, we see that there is an extra member of B whenever we try to do this; they are not the same size; B is larger than A.

But what about these two sets
N = {1,2,3,4,5,. . .} and
C = {2,3,4,5,6,. . .}
Every member of C is a member of N, but N has a member (1) that is not in C. Is N larger than C?
No, because a correspondence between the two can be created:
c = n + 1 and n = c – 1
that ties each member c of C to a unique member n of N and vice versa. They are the same size.

How about these two:
N = {1,2,3,4,5,. . .} and
D = {5281,5282,5283,5284, 5285,. . .}
Since d = n + 5280 and n = d – 5280, they are the same size even though there are 5280 members of N that are not in D.

In fact for any number k, no matter how ridiculously large, the sets
N = {1,2,3,4,5,. . .} and
E = {k+1, k+2, k+3, k+4, k+5,. . .}
are the same size, even though there are k members of E that are not in N. At this point all the smiles in the classroom were gone.

We continued, how about
N = {1,2,3,4,5,. . .} and
F = {2,4,6,8,10,. . .}
where every member of F is a member of N, but there are an infinite number of members of N that are not in F?
It’s easy to see that
n = f / 2 and f = n * 2
assigns a unique member of F to each member of N and vice versa, so here too, both sets are the same size.

By now, furrows of puzzlement and displeasure had appeared on many a brow. One clever guy in the back row tried to save the day by suggesting that all sets with an infinite number of members are the same size, causing hopeful expressions to appear on a few faces. But then, using the famous diagonal argument of Georg Cantor, we constructed an infinite set that was larger than N, and furrowed brows were everywhere.

Now what does all of this have to do with Matthew 20? To the workers who were hired first, and to us in our egalitarian culture, paying the same wage to those who worked all day as to those who only worked one hour is wildly unfair. The former worked much harder and their hourly wage is less than one tenth of the latter. Our concept of justice tells us that this is not right. Yet there is no ambiguity in the way Jesus tells the story; He intends to challenge us. Why?

Almost everyone interprets the parable as describing the relationship between God (the landowner) and us (the workers). Some scholars say that the message of the parable is straightforward: all who find their way to God are welcomed regardless of how long it takes them. Although this is a reasonable interpretation, I doubt that it removes the challenge posed by the story to a Christian who has always has led a good life when she considers the “death-bed conversion” of someone who certainly has not.

Other scholars say that the point of the parable is that we receive not what we think we deserve, but that we all receive salvation. Although this is headed in the right direction as we shall see, it is essentially the same as the first explanation, and just as challenging to the faithful Christian, I think. (I wouldn’t know, since I am one of the eleventh-hour workers.)

I think the parable is challenging because we interpret it in terms of justice or fairness, but that is not what it is about. I believe it is about love.

I think that our unease at the unequal wages paid to the workers has the same cause as the unease of my Set Theory students. All the sets they or we have ever encountered in our daily lives have been finite. Our understanding of how sets behave is based entirely on our experience with finite sets, and so our intuition tells us that all sets behave like finite sets. When we find that infinite sets behave very differently, we are confused and troubled. Jesus is telling us in Matthew 20 that our understanding of love, based entirely on our experience with fallible, inconstant, finite human love, is inadequate for comprehending the love of God. He is telling us that our understanding of love and of God is too small. This is still challenging, but in an entirely different way: Instead measuring the landowner’s (God’s) actions against the workers’ (our) expectations, we assess our expectations against the reality of a God who is infinite in time and space and whose love cannot be measured or constrained.

The problem with all parables is that they inevitably shrink God to a humanly-comprehensible scale. But the creator of all that is, is not of human scale, nor can we place our human limits on God’s boundless love.

Thanks be to God!

...I have just now, four days before I start posting the SKZ Kinktober fics, realised that posting thirty-fucking-one fics in a row means coming up with thirty-goddamnmotherfuckingfdjlasfkdja-one titles. In a row.

I mean. I did that in 2023 and 2024 Spooktober ficlets but had clearly repressed the trauma until now. 

I guess just listing the kinks doesn't count as a title? Or maybe I should go for Friends style titles, like 'The One Where...'

'The One Where Chan Finds Minho's Panties and Then Pines About It for 10K' 

'The One Where Jeongin Gets Tipsy Enough To Hit On A Buff Guy at the Bar'

'The One Where Hyunjin Is Seungmin's Birthday Present from His Dick Colleagues'

'The One Where Seungmin and Felix Try Cock Cages and Like It. A Lot.'

We did our full moon esbat tonight.  There were five of us in person plus one by phone.  The moon came up through the trees.  We lit a bonfire, did the coven business, and danced around the bonfire.  

The altar cloth was a late summer / early fall runner with golden flowers and butterflies embroidered on it.  Hilariously, a moth kept trying to pollinate the flowers!  And ignored the lantern.  :D

Prompted by A's adventures elsewhere I took another look at the bezel colours Framework offers for my laptop, to confirm that they still do not inspire me. In this I was correct. (Un?)fortunately, however, I also came across files for printing your own, along with a report from someone who printed the earlier version of the files. Might I be going to get a teal edge to my laptop screen? Maybe! Might A's bezel be changing from OEM orange to sparkly purple? Also maybe!


Cycle ride home from gym (and subsequent dinner, because I could give people money to make the problem of feeding me go away) featured a very dramatic sunset, of which have an amateurish photo (that alas could not cope with showing both the orange-pink end of the spectrum and the section of the sky down to the lower right that was doing the thing of being green):

sunset under a mackerel sky, as seen between two blocks of flats

I thought it was probably still too early in the evening for the bat, but I was wrong! So I followed up gawking at the sunset with gawking at a bat.


I have just bought my first Railcard since the start of the pandemic. It probably won't be live in time to use it for tomorrow's intended travel, but at least next time I decide I want to buy train tickets it will Already Be Sorted.


I have grudgingly succumbed to the lure of "synthetic fibres might survive a little longer than natural when it comes to, you know, cycling" and am now in possession of several second-hand Sturdy By Design lower-limb coverings. I have yet to actually get the selfie of how hilariously well the favourite shorts coordinate with the gym decor, which I had not clocked at all until I showed up wearing them; today was the leggings' first outing; I am recording this in no small part to make it easier to work out whether they are actually more robust to Indignities. I am enjoying being All The Rainbows All The Time, helped along by the part where I'm not actually willing to subject that fabric to my bike keys, so they now live on my Pride lanyard for gym-going purposes...

Children as young as four care deeply about whether their efforts matter

A new study reveals that the need to feel our efforts matter emerges surprisingly early in childhood and can shape whether we choose to put in the work.


This has useful implications.

Philosophical Questions: Technology

People have expressed interest in deep topics, so this list focuses on philosophical questions.

Is there a limit to what humans can create through technology and science?


In theory, people can create whatever can be created in this universe. But you have to go through levels. You can't build a pyramid peak floating in midair. You have to start at the bottom and build up from there. So realistically, what people can build now is iterations of current tech or breakthroughs to the next steps.

I started a commonplace book some time ago, and I've been adding notes to it as I finish books. I've finished quite a few of them, and so going back little by little to write down the things I've found has been more calming than I expected.

Today's book is: HumanKind: A Hopeful History, by Rutger Bregman. The quote I just wrote (found in chapter one, page 13 of the e-book version) said something I absolutely agree with, and is the reason I don't watch:

"The news, according to dozens of studies, is a mental health hazard."

Ya think?

1. Fandomgiftbasket is delayed another week, but down to a handful of underfilled baskets. Still needed list: https://fandomgiftbasket.dreamwidth.org/157999.html

(I have three gifts waiting for me; I know that two of them are Original Work but the third is a mystery. I can't fill any of the needy baskets but I'm taking advantage of the delay to write fic for some non-needy ones.)

2. Yuletide nominations are starting to get approved! For me, the visual novel "The Letter" got approved straight off; as of today it has 78 works before filters. I nominated Marianne and someone asked me to nominate Zachary. I'm still waiting on Excellent Women, Meow Palace, The Ghost Who Limped, and Life After Magic (which I nominated at the request of someone else). Life After Magic and one of its characters is wrangled, the rest are not.

ETA: Meow Palace got approved! I expect the next few will take a while because they require researching.

3. Meow Palace: Forbidden City got updated to 0.6.1; I'm not sure why they didn't introduce the two new characters (and 3 new locations) at 0.6, which seemed to only introduce time-locked events. Still, I found a new favorite NPC in the form of Grandpa Huang, who seems to be the main physician there? Currently, I'm hanging about in a location with no NPCs so I'm spending some time honing some of my early skills in a place I'm not likely to be interrupted. Then I'll see if Grandpa Huang will send me on to the second new NPC.

Ancient meteorites reveal a powerful force that helped build the Solar System

Ancient meteorite grains reveal that powerful magnetism may have helped shape the solar system from its very beginning.

Ancient grains inside one of the oldest known meteorites reveal that a surprisingly strong magnetic field existed during the solar system’s first 200,000 years. The discovery suggests magnetism worked alongside gravity to help transform a vast cloud of gas and dust into the sun and planetary disk.

  1. I have FINISHED indexing (in the EatYourBooks sense) a cookbook I was threatening to stall on.
  2. Indexing sure is getting me to actually properly read a lot of cookbooks about which I had vague curiosity! I am glad to be doing the reading and also, perversely, glad to discover that the majority of them are of limited interest to me for any purpose other than reading approximately once. (Alas that indexing takes reading at least twice...)
  3. The magic that is international video calls.
  4. A few weeks ago I bought some freeze-dried raspberry powder to see what I thought of adding it to protein shakes; I'm indifferent to that but really enjoying having a tablespoon or so of the stuff in my breakfast mush.
  5. Sourdough bread and its willingness to just keep on being food long after it was baked and without any especial care being taken of it.

I really enjoyed Green City Wars despite the shocking lack of spiders, which is my usual metric for how likely I am to enjoy a Tchaikovsky book. However, I will say, our protagonist sure is slow on the uptake as to what, exactly, his mouse target may have invented. Also, plangent is a really, really weird word to pick to be the name of the intelligence booster drug. Who was in charge of that decision in-universe!?

As for The Raven Scholar, this is my third try at reading it, and the first time I got past the prologue. Thank goodness we're not in their viewpoint for the entire book, because omg I just could not. The rest of the book has a viewpoint I much prefer, thank you. And that twist really did shock me! My goodness, the villain really is a nasty piece of work.

Sheep and horses may help grasslands lock more carbon underground

Grasslands in Iceland stored more topsoil carbon with continued grazing, suggesting livestock removal does not always benefit carbon storage.


Compare this with Pleistocene Park, which aims to emulate the mammoth steppe. Lots of large grazing animals improve habitat and carbon storage.  That helps buffer the impact of climate change.
