在人工智能塑造的时代,古怪与创造力比死记硬背的技能更重要,因为语言模型擅长记忆和档案研究,却仍困于缺乏研究品味的“中位”视角。作者回忆起牛津科学史学者艾伦·查普曼博士,其古怪的好奇心改变了人生。查普曼通过“无用”的异域知识——苏美尔六十进制数学、燃素理论——进行教学,坚持科学史需要进入过时的世界观,而非复述凯旋式的发现。这种“无用知识”构成了研究品味的基础。他深奥的知识覆盖面(罗伯特·胡克、安提基特拉装置、中世纪自动机)体现了不靠逆反心理的非显而易见思考。随着 AI 代理越来越多地引导研究,我们必须抵制认识论的收窄;模型执行定义明确的任务,却难以进行开放性探索。我们需要能够进入异域过往世界观的人,扩展的不只是我们所知,还有我们如何思考。查普曼对异域知识体系的热情投入永远改变了作者的观念。

“Variety, not uniformity, is more likely to be the key to progress. The genius of being is whimsical rather than consistent. Our strata show broken bones of histories all forgotten.” — Benjamin Blood, as quoted by William James, 1911

I’m sometimes asked how I think history education and research will change in an era being reshaped by AI. I don’t trust anyone who claims certainty on the topic, because “AI” is such a moving target (and its impacts on the humanities so poorly understood) that any views are provisional.

But, it seems to me that we are entering an era in which traits like eccentricity and creativity are going to matter much more than before. Language models excel at pedagogies involving memorization, spaced repetition, and customized feedback. They are also getting good at “brute force” archival research. Yet they remain stuck in a median perspective, a sort of averaged-out, clichéd intellectual blandness that helps explain why frontier models still lack “research taste” in humanistic disciplines. (I think this is also why different frontier models converge on an oddly similar tone and subject matter when it comes to creative writing).

This got me thinking about which of my own teachers were most unexpected, most “out of distribution,” relative to the intellectual paths that AI systems converge on. The first person I thought of was a man I knew for only about nine months, when I was a visiting student at Oxford as a twenty-year-old. But the time I spent with Dr. Allan Chapman, who passed away earlier this year, was genuinely life-altering for me.

And the reason was because he was so immersed in the foreign country of past minds that he was almost like a time traveler.

In the coming years, as I’ll argue below, I believe this ability to draw from alien worlds of thought will become both more important and more rare.

On one level, Allan Chapman was a cliché. As might be apparent from the screenshot above — from one of his several television appearances as a history presenter — Chapman embraced the persona of an Oxbridge don. He wore a waistcoat, he had floppy hair, and he spent much of his life pacing rain-misted medieval quadrangles.

This reminiscence from one of his students in the late 1970s matches the version of him I met circa 2005:

Allan was a true eccentric, kind, friendly and always ready to share his enthusiasm for the history of science, especially the human stories that always form the basis of science. He always sported impressive ginger sideburns like a Victorian gentleman, dressed in tweeds and a deerstalker, and wore wire-rim glasses. I remember he always carried two pocket watches in his waistcoat pockets, as wristwatches were not his thing. One of the timepieces was set on GMT and the other on Oxford local mean sidereal time, so in summer neither would actually tell the correct local time.

I remember my initial tutorial meetings with Allan taking place in Oxford’s history faculty building, but he soon proposed that we begin meeting, instead, at a local pub: the King’s Arms. As I recall, he always ordered a strong cup of tea. I don’t believe I’ve ever met a human being who enjoyed tea more than Allan Chapman.

One week, he explained to me that we would have to reschedule our meeting because he was due to have tea, instead, with the Archbishop of Canterbury (“an old school fellow, you know — I do hope you will understand”).

As a newcomer to English society, all of this led me to assume that Chapman was an upper-class, Evelyn Waugh sort of character. Slowly, though, it dawned on me that he was in fact just the opposite. As he put it in an interview:

I came from a hard-working, intelligent and loving working-class family, but to whom going to university was on roughly the same level as going to the Moon… An academic education was not on the horizon. The bright lads became electricians, the less bright went into semi-skilled jobs, and for the rest it was the mill, the factory or the pit.

He was fascinated by machinery of all kinds, an expert in clockwork, geared devices, and telescopes. But most of all, he was an expert in extracting meaning out of seemingly useless knowledge.

Allan was my first introduction to the field of history of science. He began our lessons in a way that I found baffling. He insisted that I learn the rudiments of Sumerian-Babylonian astronomy, mathematics and the “base-60” number system. This sort of thing, in other words:

Allan never fully explained to me why this was so important to him. At first, I found this deeply frustrating. Surely, I told myself, wasting my time doing multiplication in cuneiform script was useless knowledge.

It eventually became apparent that this was exactly what he wanted me to learn.

I never did get the hang of multiplication in base-60, and I never will. But what I learned from the experience of trying to learn this arcane field ended up changing my life.

The meta-lesson I took away from it boils down to this:

The history of science only makes sense if we focus with all of our hearts and minds on understanding useless things, alien epistemologies, and outmoded ideas.

Why did highly intelligent people believe in phlogiston? How did Sumerians calculate without the use of a zero? How did Tycho Brahe’s theory of the solar system work, and why was it convincing?

If you teach the history of science, medicine, and technology only as a series of triumphant discoveries, you fail to capture the thought processes that actually led to those discoveries — and the thousand other wrong turns and odd byways that coexisted and competed with them. And if you miss those thousand wrong turns, you miss the raw materials that allow us to usefully analyze the choices made by actors at the time.

In other words, useless knowledge is not useless at all. It is, in fact, the foundation of developing research taste in history.

Allan had a mind drawn to the non-obvious — to variety, rather than uniformity. He was, for instance, one of the world experts on Robert Hooke, a close associate (and at times, a bitter enemy) of Isaac Newton. Hooke may well be the most consequential scientific figure who is not a household name, in part because his interests were scattered across a dozen different fields, from architecture to microscopy (he was even the author of the first scientific paper on the psychoactive effects of cannabis).

Some other things I remember Chapman talking about, to give you a sense of his own arcane range of interests:

• Aristotle’s love of marine biology

• The Antikythera mechanism

• Do aliens exist?

• How do medieval clocks work?

• Cornelis Drebbel’s 1620 submarine

• Medieval Islamic automata

• Giordano Bruno and the problem of evil in an infinite cosmos

Thinking in ways that are “out of distribution” (in the sense of not falling within the expected range) does not mean being contrarian in the Silicon Valley sense. Chapman was not a reactionary. He did not disagree simply to disagree, and he was not a polemicist or an ideologue.

He was just really, really curious.

In a recent post about the question of recursive self-improvement in AI systems, Dean W. Ball notes that research taste is “incredibly challenging to measure objectively.” It may be that this is not a question of scaling up more compute — that, instead, there is some qualitative difference between an AI system achieving good results in clearly-defined domains involving a task, and the same system being original in a human-like way:

The questions “can the model do this [even halfway specified thing] well?” and “does the model know what to do next in open-ended intellectual exploration?” are distinct from one another, and this distinction should not be dismissed—as it too often is—as “insufficiently AGI-pilled.” The reality is we do not know how much this distinction matters, and do not know how long it will take for models to master “taste” in open-ended intellectual domains.

As AI agents increasingly guide how human researchers think, it is essential that we push back against the “epistemological narrowing” that results from their training incentives. A system optimized for writing clean code or for providing helpful answers may in fact prove distinctly unhelpful when tasked with finding something new in fields, like history, which cannot provide immediate feedback about whether an idea is promising or not.

And it’s not just AI systems that flatten us epistemologically, but also a larger culture of algorithmic influence and mimicry. And this is why, in the 2020s, we need people like Chapman more than ever: people who are able not just to talk about, but to inhabit alien worldviews from past human cultures.

When I look back on my attempts to learn Sumerian math — Allan with his cup of tea, clearly delighting in the process that I found so deeply annoying — I readily acknowledge that this was a skill I received absolutely zero practical benefit from. No job application requires it. Unlike a lot of the drug lore I learned in researching The Age of Intoxication, it’s not even a fun fact to bring up at dinner parties.

But the exuberant way he worked within this alien knowledge system will always be meaningful to me. It has stuck in my mind because it expanded not just what I knew, but how I thought.

Before Chapman, I had been told that other number systems and other cosmologies existed.

But I had never been asked to actually try to live inside them.

That’s a very different proposition. Quite literally, a mind-expanding one.

• Some of Allan’s lectures, on everything from Christianity and the history of mental illness to secularization and the Enlightenment.

• From Robert Hooke’s 1689 account of cannabis: “it seemeth to put a Man into a Dream, or make him asleep, whilst yet he seems to be awake, but at last ends in a profound Sleep, which rectifies all.”

• I made a “neuron atlas” for Talkie, which charts some of the more interesting effects that occur when you “push” an individual neuron in the model up or down - for instance, there is a particular neuron which seems to induce the model to believe it is a fictional character or author stuck inside one of their novels. Here are a few more:

• AI safety researcher Joshua Fonseca Rivera (whose example I was following for the above) has produced a full set of atlases of a dozen models here.
