Mutable stability in the transmission of medieval texts

I’ve just checked in at Academica.edu and was alerted to this article:

Stephen G. Nichols, Mutable Stability, a Medieval Paradox: The Case of Le Roman de la Rose, Queste 23 (2016) 2, pp. 71-103.

I’ve not yet read it, but a quick skim makes it clear that it speaks to a current debate in cultural evolution concerning the high-fidelity transmission of “memes” (Dan Dennett) vs. the variable transmission of objects as guided by “factors of attraction” (Dan Sperber). I’ve not yet read it, but here’s some tell-tale passages. This is from the beginning (p. 71):

Yet even those who argue, to the contrary, that ‘transmission errors’ often represent creative ‘participation’ by a talented scribe, must recognize the attraction of a stable work.After all, despite an extraordinary record of innovation, invention, and discovery, the Middle Ages are an era that resisted change in and for itself. And yet this same veneration of conservative values underlies a fascinating paradox of medieval culture: its delicate and seemingly contradictory balance between stability, on the one hand, and transformation, on the other. It may be that only an era that saw no contradiction in promulgating an omnipotent, unchanging divinity, which was at the same time a dynamic principle of construction and transformation, could have managed the paradox of what I want to call ‘mutable stability’.

Here’s Dawkins in the 2nd chapter of The Selfish Gene:

Darwin’s ‘survival of the fittest’ is really a special case of a more general law of survival of the stable. The universe is populated by stable things. A stable thing is a collection of atoms that is permanent enough or common enough to deserve a name. It may be a unique collection of atoms, such as the Matterhorn, that lasts long enough to be worth naming. Or it may be a class of entities, such as rain drops, that come into existence at a sufficiently high rate to deserve a collective name, even if any one of them is short-lived. The things that we see around us, and which we think of as needing explanation–rocks, galaxies, ocean waves–are all, to a greater or lesser extent, stable patterns of atoms.

Etc.

Back to Nichols, a bit later in the article (p. 77):

In this case, however, it’s one that allows us to understand the paradox of medieval narrative forms whose ‘stability’ over time – in some cases over several centuries – depends on what I call the generative – or regenerative – force of transmission. Why ‘regenerative’ if transmission involves reproducing the ‘same’ work from one representation to another? The answer to that question involves recognizing the complex forces at play in the transmission of me- dieval texts, beginning with concepts like ‘the same’ and ‘seeing’ or ‘perspective’. After all, in a culture where the technology of transmission depends on copying each text by hand, what the scribe sees, or thinks she or he sees, must be factored into our definition of ‘sameness’ when comparing original and copy.

In the event, ‘sameness’, for the medieval mind had a very different connotation from our modern senses of the term. Indeed, it even involves a different process of perception and imagination. Whereas in our age of mechanical and digital reproduction, we are used to standards of ‘exactness’ for things we recognize as identical, me- dieval people had neither the means nor the expectation to make ‘same’ and ‘exact imitation’ synonymous. Indeed, one may even question the existence at that time of such a concept as ‘exact imitation’, at least as we understand it.

Ontology and Cultural Evolution: “Spirit” or “Geist” and some of its measures

This post is about terminology, but also about things – in particular, an abstract thing – and measurements of those things. The things and measurements arise in the study of cultural evolution.

Let us start with a thing. What is this?

9dot3

If you are a regular reader here at New Savanna you might reply: Oh, that’s the whatchamacallit from Jocker’s Macroanalysis. Well, yes, it’s an illustration from Macroanalysis. But that’s not quite the answer I was looking for. But let’s call that answer a citation and set it aside.

Let’s ask the same question, but of a different object: What’s this?

20141231-_IGP2188

I can imagine two answers, both correct, each it its own way:

1. It’s a photo of the moon.

2. The moon.

Strictly speaking, the first is correct and the second is not. It IS a photograph, not the moon itself. But the second answer is well within standard usage.

Notice that the photo does not depict the moon in full (whatever that might mean), no photograph could. That doesn’t change the fact that it is the moon that is depicted, not the sun, or Jupiter, or Alpha Centauri, or, for that matter, Mickey Mouse. We do not generally expect that representations of things should exhaust those things.

Now let us return to the first image and once again ask: What is this? I want two answers, one to correspond with each of our answers about the moon photo. I’m looking for something of the form:

1. A representation of X.

2. X.

Let us start with X. Jockers was analyzing a corpus of roughly 3300 19th century Anglophone novels. To do that he evaluated each of them on each of 600 features. Since those evaluations can be expressed numerically Jockers was able to create a 600-dimensional space in which teach text occupies a single point. He then joined all those points representing texts that are relatively close to one another. Those texts are highly similar with respect to the 600 features that define the space.

The result is a directed graph having 3300 nodes in 600 dimensions. So, perhaps we can say that X is a corpus similarity graph. However, we cannot see in 600 dimensions so there is no way we can directly examine that graph. It exists only as an abstract object in a computer. What we can do, and what Jockers did, is project a 600D object into two dimensions. That’s what we see in the image.

Monkey vocal tracts are speech-ready

A new paper in Science Advances (Fitch, de Boer, Mathur & Ghazanfar, 2016) uses models informed by x-rays of macaque vocal tracts to claim that monkeys have the tools neccessary to make enough speech sounds to create a productive spoken language. This means that the evolution of speech is likely to be primarily dependent on cognitive adaptation, rather than adaptation of the vocal tract.

Abstract here:

For four decades, the inability of nonhuman primates to produce human speech sounds has been claimed to stem from limitations in their vocal tract anatomy, a conclusion based on plaster casts made from the vocal tract of a monkey cadaver. We used x-ray videos to quantify vocal tract dynamics in living macaques during vocalization, facial displays, and feeding. We demonstrate that the macaque vocal tract could easily produce an adequate range of speech sounds to support spoken language, showing that previous techniques based on postmortem samples drastically underestimated primate vocal capabilities. Our findings imply that the evolution of human speech capabilities required neural changes rather than modifications of vocal anatomy. Macaques have a speech-ready vocal tract but lack a speech-ready brain to control it.

Mint journal club over at ICCI

Since finishing my PhD I’ve been lucky enough to get a position at the Max Planck Institute for the Science of Human History. Specifically, I’m working at the Minds and Traditions research group (the Mint), where we focus on one key aspect of cultural transmission: the evolution of graphic codes.

The reason I’m bringing this up is because the Mint is currently running a journal club over at the (recently revamped) International Cognition & Culture Institute (ICCI). This month we’re reading Franke & Jäger’s paper on Probabilistic pragmatics, or why Bayes’ rule is probably important for pragmatics (click here for open access version). The journal club is open to everyone, and not just Mint members, so feel free to pop over, read the paper, and leave a comment.

Sharing Experience: Computation, Form, and Meaning in the Work of Literature

I’ve uploaded another document: Sharing Experience: Computation, Form, and Meaning in the Work of Literature. You can download it from Academia.edu:

https://www.academia.edu/28764246/Sharing_Experience_Computation_Form_and_Meaning_in_the_Work_of_Literature

It’s considerably revised from a text I’d uploaded a month ago: Form, Event, and Text in an Age of Computation. You might also look at my post, Obama’s Affective Trajectory in His Eulogy for Clementa Pinckney, which could have been included in the article, but I’m up against a maximum word count as I am submitting the article for publication. You might also look at the post, Words, Binding, and Conversation as Computation, which figured heavily in my rethinking.

Here’s the abstract of the new article, followed by the TOC and the introduction:

Abstract

It is by virtue of its form that a literary work constrains meaning so that it can be a vehicle for sharing experience. Form is thus an intermediary in Latour’s sense, while meaning is a mediator. Using fragments of a cognitive network model for Shakespeare’s Sonnet 129 we can distinguish between (1) the mind/brain cognitive system, (2) the text considered merely as a string of signifiers, and (3) the path one computes through (1) under constraints imposed by (2). As a text, Obama’s Eulogy for Clementa Pinckney is a ring-composition; as a performance, the central section is clearly marked by audience response. Recent work on synchronization of movement and neural activity across communicating individuals affords insight into the physical substrate of intersubjectivity. The ring-form description is juxtaposed to the performative meaning identified by Glenn Loury and John McWhorter.

Introduction: Speculative Engineering

The conjunction of computation and literature is not so strange as it once was, not in this era of digital humanities. But my sense of the conjunction is differs from that of computational critics. They regard computation as a reservoir of tools to be employed in investigating texts, typically a large corpus of texts. That is fine [1].

Digital critics, however, have little interest in computation as a process one enacts while reading a text, the sense that interests me. As the psychologist Ulric Neisser pointed out four decades ago, it was computation that drove the so-called cognitive revolution [2]. Much of the work in cognitive science is conducted in a vocabulary derived computing and, in many cases, involves computer simulations. Prior to the computer metaphor we populated the mind with sensations, perceptions, concepts, ideas, feelings, drives, desires, signs, Freudian hydraulics, and so forth, but we had no explicit accounts of how these things worked, of how perceptions gave way to concepts, or how desire led to action. The computer metaphor gave us conceptual tools for constructing models with differentiated components and processes meshing like, well, clockwork. Moreover, so far as I know, computation of one kind or another provides the only working models we have for language processes.

My purpose in this essay is to recover the concept of computation for thinking about literary processes. For this purpose it is unnecessary either to believe or to deny that the brain (with its mind) is a digital computer. There is an obvious sense in which it is not a digital computer: brains are parts of living organisms; digital computers are not. Beyond that, the issue is a philosophical quagmire. I propose only that the idea of computation is a useful heuristic: it helps us think about and systematically describe literary form in ways we haven’t done before.

Though it might appear that I advocate a scientific approach to literary criticism, that is misleading. Speculative engineering is a better characterization. Engineering is about design and construction, perhaps even Latourian composition [3]. Think of it as reverse-engineering: we’ve got the finished result (a performance, a script) and we examine it to determine how it was made [4]. It is speculative because it must be; our ignorance is too great. The speculative engineer builds a bridge from here to there and only then can we find out if the bridge is able to support sustained investigation.

Caveat emptor: This bridge is of complex construction. I start with form, move to computation, with Shakespeare’s Sonnet 129 as my example, and then to President Obama’s Eulogy for Clementa Pinckney. After describing its structure (ring-composition) I consider the performance situation in which Obama delivered it, arguing that those present constituted a single physical system in which for sharing experience. I conclude by discussing meaning, history, and attachment.

A forthcoming exhibition in  Dresden, Germany entitled “LANGUAGE: THE WORLD OF WORDS, SIGNS, AND GESTURES” will feature an interesting language evolution experiment.

In the experiment, conducted by Dr Christine Cuskley at the University of Edinburgh, you learn an alien language called Ferro. Since the more participants the merrier, you can also learn Ferro from your computer at home!

So if you want to learn Ferro and participate in language evolution research you can do so here!

 

10 post-docs join new language evolution group in Nijmegen

In 2016 and 2017, ten post-doc researchers will join the MPI for Psycholinguistics in Nijmegen to form the Language Evolution and Interaction Scholars of Nijmegen group (LEvInSON).

The group will explore the biological and cultural origins of language, and how they are linked through social interaction. The group, led by Stephen Levinson, Seán Roberts and Mark Dingemanse, will be hosted by the Language and Cognition department.

The visitors include researchers specializing in experimental approaches (Hannah Little, Yasamin Motamedi, Alan Nielsen, Justin Sulik), computational modelling (Kevin Stadler, Bill Thompson), animal communication (Marcus Perlman, Andrea Ravignani), comparative linguistics (Piera Filipi), and conversational interaction (Ashley Micklos).

levinsongroup

Tessa Verhoef, who was awarded a VENI grant to study the evolution of linguistic structure, will also join the group.  All together, this will be one of the largest groups studying language evolution in the world.

Several senior researchers will visit throughout the period, including Vera Kempe (Abertay University), Monica Tamariz (University of Edinburgh), Gary Lupyan (University of Wisconsin-Madison), Cedric Boeckx (ICREA/Universitat de Barcelona) and Bart de Boer (Vrije Universiteit Brussel).

Words, Binding, and Conversation as Computation

I’ve been thinking about my draft article, Form, Event, and Text in an Age of Computation. It presents me with the same old rhetorical problem: how to present computation to literary critics? In particular, I want to convince them that literary form is best thought of as being computational in kind. My problem is this: If you’ve already got ‘it’, whatever it is, then my examples make sense. If you don’t, then it’s not clear to me that they do make sense. In particular, cognitive networks are a stretch. Literary criticism just doesn’t give you any useful intuitions of form as being independent of meaning.

Any how, I’ve been thinking about words and about conversation. What I’m thinking is that the connection between signifier and signified is fundamentally computed in the sense that I’m after. It’s not ‘hard-wired’ at all. Rather it’s established dynamically. That’s what the first part of this post is about. The second part then goes on to argue that conversation is fundamentally computational.

This is crude and sketchy. We’ll see.

Words as bindings between sound and sense

What is a word? I’m not even going to attempt a definition, as we all know one when we see it, so to speak. What I will say, however, is that the common-sense core intuition tends to exaggeration their Parmenidean stillness and constancy at the expense of the Heraclitean fluctuation. What does this word mean:

race

It’s a simple word, an everyday word. Out there in the middle of nowhere, without context, it’s hard to say what it means. I could mean this, it could mean that. It depends.

When I look it up in the dictionary on my computer, New Oxford American Dictionary, it lists three general senses. One, “a ginger root,” is listed as “dated.” The other two senses are the ones I know, and each has a number of possibilities. One set of meanings has to do with things moving and has many alternatives. The other deals with kinds of beings, biological or human. These meanings no doubt developed over time.

And, of course, the word’s appearance can vary widely depending on typeface or how it’s handwritten, either in cursive script or printed. The spoken word varies widely as well, depending on the speaker–male, female, adult, child, etc.–and discourse context. It’s not a fixed object at all.

What I’m suggesting, then, is that this common ‘picture’ is too static:

sign

There we have it, the signifier and the signified packaged together in a little ‘suitcase’ with “sign” as the convenient handle for the package. It gives the impression the sentences are little ‘trains’ of meaning, with one box connected to the next in a chain of signifiers.

No one who thinks seriously about it actually thinks that way. But that’s where thinking starts. For that matter, by the time one gets around to distinguishing between signifier and signified one has begun to move away from the static conception. My guess is that the static conception arises from the fact of writing and the existence of dictionaries. There they are, one after another. No matter when you look up a word, it’s there in the same place, having the same definition. It’s a thing, an eternal Parmenidean thing.

Later in The Course in General Linguistics, long after he’s introduced the signifier/signified distinction, de Saussure presents us with this picture [1]:

waves sign

He begins glossing it as follows (112): “The linguistic fact can therefore be pictured in its totality–i.e. language–as a series of contiguous subdivisions marked off on both the indefinite plane of jumbled ideas (A) and the equally vague plane of sounds (B).” He goes on to note “the somewhat mysterious fact is rather that ‘thought-sound’ implies division, and that language words out its units while taking shape between two shapeless masses.” I rather like that, and I like that he chose undulating waves as his visual image.
