Rabbi Zohar Atkins’ published an essay recently, “When Knowledge Is Cheap, Insight Is Everything: Jevons Paradox applied to Torah Learning.”
Articles referencing Jevons are everywhere these days. I myself wrote “Radiology Isn’t an Example of Jevons Paradox” last December. Atkins’ essay is a change of pace:
It is worth pausing here to note that the rabbinic tradition was not, in the nineteenth century, sitting around waiting for an English economist to explain to it how human desire interacts with supply.
The book of Kohelet, known in English as Ecclesiastes, already observed that the eye is not satisfied with seeing, nor the ear filled with hearing (Kohelet 1:8). The Talmud, in Sukkah 52b, sharpens the principle into a structural law: there is a small organ in a person, the Gemara says, which when starved is satisfied and when satisfied is starved. On the same page, the sage Abaye generalizes: the greater a person, the greater his appetite. The early rabbinic anthology Kohelet Rabbah (1:13) gives the principle its proverbial form: a man with a hundred wants two hundred. The eighteenth-century ethical work Mesillat Yesharim, the standard Jewish text on moral psychology, makes the same observation as a developmental claim: indulgence does not satisfy desire, it expands desire’s capacity (chapters 1 and 13). The nineteenth-century commentator Malbim, glossing the book of Proverbs (21:17), says the same of pleasure as such: attachment enlarges want rather than quieting it.
This passage concerns the same never-full eye concept I shared last year from this parable as relayed by Gluckel, a seventeenth-century Jewish widow, in her memoirs. It is one mixed and rephrased over generations because the new formulations can still provide novel insights and continue grounding us as individuals, even if there is “nothing new under the sun” (Kohelet 1:9).
This is the same observation Jevons made about coal, transposed from industrial input to human desire. Or rather, Jevons’s observation about coal is the same one Kohelet made about the eye, transposed from human desire to industrial input.
Layers upon layers of commentary, authors quoting primary texts and each other, building up a multilayer discourse. It has become a popular theme among techno-optimists writing about AI that there is some ineffable human quality that AI makes more valuable as the raw material becomes cheaper (like critical thinking, judgment, or taste). I think that remains to be seen, but there is a parallel argument that our thinking, our judgement, and our taste matter for us, and possibly our community:
AI is the new master of wheat. It is unusually capable at producing the relevant source, the right translation, the missing citation. Information was never the goal. A learner who consumes AI-generated wheat by the handful, who asks ChatGPT for the meaning of the weekly Torah portion and stops there, has eaten dry grain and gone home thinking she has tasted Torah. She has tasted the input. The tradition lives in what gets made from it.
Great analogy.
The vocation of the learner in the age of cheap wheat is to become a baker: to take the now-abundant raw material and turn it into something a human can eat. Chiddush that surfaces structure. Communities that perpetuate the learning. Students who teach each other when the teacher is gone. This is true for the rabbi and it is true for the nineteen-year-old in Be’er Sheva, because the obligation was always universal in principle (Chagigah 3a). The economics restricted it. The economics just changed.
Chiddush is the Hebrew term for an original insight (particularly with regard to Jewish thought as it pertains to the study of Torah and the Talmud). The point that Atkins makes so well is not that such insights could only come from humans; it’s that doing so is the human thing to do. That strivers must strive. That cheap information would be best if it helped make communities of learning, which would finally fulfill the promise of the early internet/open web.
Jevons’ coal built a new England, more dependent on coal than the old one and more capable of using it. Cheap knowledge will build a new Torah world, more dependent on the corpus than the old one and more capable of working it. The question is whether the people inside that world will recognize the work for what it is and pick up the rolling pin.
I find myself thinking often about the humans from the movie WALL-E on the galactic cruise ship and wondering how we will answer that question.
