Gender without Gender Identity: The Case of Cognitive Disability. Elizabeth Barnes

Filed under: Uncategorized — E @ 7:10 am

What gender are you? And in virtue of what? These are questions of gender categorization. Such questions are increasingly at the core of many contemporary debates about gender, both within philosophy and in public discourse.

Growing efforts are being made to highlight the importance of gender identity to gender categorization. Philosophical theories of gender have traditionally focused on gender role—the social norms, obligations, and positions that others impose on you based on perceived gender. But the experiences of trans, non-binary, and gender nonconforming people have shown that an exclusive focus on gender role is inadequate for theorizing gender. We also need to consider a person’s relationship to gender categories and gender norms. Two people might both be perceived by others as women, but while one thinks of herself as a woman the other thinks of themself as genderqueer. And this difference in gender self-identification is not merely a difference in personal feeling. A gender nonconforming woman and a genderqueer person—even if they are treated similarly by others—will often experience and navigate gender norms and roles quite differently, and this difference matters to a full understanding of gender.

In what follows, I am by no means attempting to dispute that gender identity is an important aspect of gender and gender categorization. Rather, I’m going to argue that we shouldn’t swing the pendulum too far the other way. It’s become increasingly common, in both popular and philosophical explanations of gender, to claim that gender identity uniquely determines one’s gender, that is, that gender categorization is solely a matter of gender self-identification. That, I’ll argue, is too strong. While gender identity matters, it isn’t the sole determinant of gender.

Identity-based views of gender categorization put a cognitive requirement on gender membership. One must identify as gender x in order to be classed as gender x. Identifying as gender x, at least on extant philosophical theories of gender identity, is a matter of complex social reasoning and self-understanding. It requires awareness of various social norms and roles (and, moreover, an awareness of them as gendered), the ability to articulate one’s own relationship to those norms and roles, and so on. But many cognitively disabled people have little or no access to language. Many tend not to understand social norms, much less to identify those norms as specifically gendered. And many lack the type of social and interpersonal awareness to be able to make judgements about their own ‘sense of gender’. This won’t, of course, be the case for all cognitively disabled people, and it’s important to acknowledge that there is a wide range of cognitive and social experiences that fall within the broad heading ‘cognitive disability’. In what follows, I don’t mean to paint all cognitively disabled people with the same broad brush, or to assume that all cognitively disabled people are incapable of having a strongly felt sense of gender self-identification. One only needs to look, for example, at the vibrant drag culture among some people with Downs Syndrome to see how richly some people with cognitive disabilities experience gender via self-expression and self-identification.

But the wide range of cognitive disability—and the specific ways in which cognitive disability can affect social understanding and social reasoning—make it plausible that many cognitively disabled people simply don’t have this type of highly developed sense of their own.

The worthwhile problems are the ones you can really solve. Da una lettera di Richard Feynman

Filed under: Uncategorized — E @ 10:16 pm

Dear Koichi,

I was very happy to hear from you, and that you have such a position in the Research Laboratories. Unfortunately your letter made me unhappy for you seem to be truly sad. It seems that the influence of your teacher has been to give you a false idea of what are worthwhile problems. The worthwhile problems are the ones you can really solve or help solve, the ones you can really contribute something to. A problem is grand in science if it lies before us unsolved and we see some way for us to make some headway into it. I would advise you to take even simpler, or as you say, humbler, problems until you find some you can really solve easily, no matter how trivial. You will get the pleasure of success, and of helping your fellow man, even if it is only to answer a question in the mind of a colleague less able than you. You must not take away from yourself these pleasures because you have some erroneous idea of what is worthwhile.

You met me at the peak of my career when I seemed to you to be concerned with problems close to the gods. But at the same time I had another Ph.D. Student (Albert Hibbs) was on how it is that the winds build up waves blowing over water in the sea. I accepted him as a student because he came to me with the problem he wanted to solve. With you I made a mistake, I gave you the problem instead of letting you find your own; and left you with a wrong idea of what is interesting or pleasant or important to work on (namely those problems you see you may do something about). I am sorry, excuse me. I hope by this letter to correct it a little.

I have worked on innumerable problems that you would call humble, but which I enjoyed and felt very good about because I sometimes could partially succeed. For example, experiments on the coefficient of friction on highly polished surfaces, to try to learn something about how friction worked (failure). Or, how elastic properties of crystals depends on the forces between the atoms in them, or how to make electroplated metal stick to plastic objects (like radio knobs). Or, how neutrons diffuse out of Uranium. Or, the reflection of electromagnetic waves from films coating glass. The development of shock waves in explosions. The design of a neutron counter. Why some elements capture electrons from the L-orbits, but not the K-orbits. General theory of how to fold paper to make a certain type of child’s toy (called flexagons). The energy levels in the light nuclei. The theory of turbulence (I have spent several years on it without success). Plus all the “grander” problems of quantum theory.

No problem is too small or too trivial if we can really do something about it.

You say you are a nameless man. You are not to your wife and to your child. You will not long remain so to your immediate colleagues if you can answer their simple questions when they come into your office. You are not nameless to me. Do not remain nameless to yourself – it is too sad a way to be. now your place in the world and evaluate yourself fairly, not in terms of your naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher’s ideals are.

Best of luck and happiness. Sincerely, Richard P. Feynman.

L’Orlando furioso. Le penne e i destrieri

Filed under: Uncategorized — E @ 2:29 am

La bella donna tuttavolta priega
ch’invan la dura squama oltre non pesti.
— Torna, per Dio, signor: prima mi slega
(dicea piangendo), che l’orca si desti:
portami teco e in mezzo il mar mi anniega:
non far ch’in ventre al brutto pesce io resti. —
Ruggier, commosso dunque al giusto grido,
slegò la donna, e la levò dal lido.

(…)

Quivi il bramoso cavallier ritenne
l’audace corso, e nel pratel discese;
e fe’ raccorre al suo destrier le penne,
ma non a tal che piú le avea distese.
Del destrier sceso, a pena si ritenne
di salir altri; ma tennel l’arnese:
l’arnese il tenne, che bisognò trarre,
e contra il suo disir messe le sbarre.

Frettoloso, or da questo or da quel canto
confusamente l’arme si levava.
Non gli parve altra volta mai star tanto;
che s’un laccio sciogliea, dui n’annodava.
Ma troppo è lungo ormai, Signor, il canto,
e forse ch’anco l’ascoltar vi grava:
si ch’io differirò l’istoria mia
in altro tempo che piú grata sia.

La solitudine

Filed under: Uncategorized — E @ 1:42 am

La solitudine – a volerla debitamente definire – è di tre tipi: del luogo …; del tempo, ovverosia delle notti, quando anche nel foro c’è solitudine e silenzio; dell’animo, ovverosia di quelli che, per la straordinaria capacità di concentrarsi nella contemplazione, si sottraggono al mezzogiorno e alla piazza affollata e ignorano che cosa vi succeda e sono soli in qualunque momento e luogo vogliano esserlo.

Natural Semantic Metalanguage (NSM)

Filed under: Uncategorized — E @ 12:36 pm

The Natural Semantic Metalanguage approach, originated by Anna Wierzbicka, can lay claim to being the most well-developed, comprehensive and practical approach to cross-linguistic and cross-cultural semantics on the contemporary scene. It has been applied to over 30 languages from many parts of the world.

The NSM approach is based on evidence that there is a small core of basic, universal meanings, known as semantic primes, which can be expressed by words or other linguistic expressions in all languages. This common core of meaning can be used as a tool for linguistic and cultural analysis: to explain the meanings of complex and culture-specific words and grammatical constructions (using semantic explications), and to articulate culture-specific values and attitudes (using cultural scripts). The theory also provides a semantic foundation for universal grammar and for linguistic typology.

Using NSM allows us to formulate analyses which are clear, precise, cross-translatable, non-Anglocentric, and intelligible to people without specialist linguistic training.

The method has applications in intercultural communication, lexicography (dictionary making), language teaching, the study of child language acquisition, legal semantics, and other areas.

 

For an example of an explication of a meaning which will be unfamiliar to most readers, we can take the Japanese word amae. According to Takeo Doi (1974, 1981), amae is a “peculiarly Japanese emotion” which “runs through all the various activities of Japanese society” and represents “the true essence of Japanese psychology”. So what exactly is amae? Doi explains that it is the noun form of amaeru, an intransitive verb which means ‘to depend and presume upon another’s benevolence’. It indicates ‘helplessness and the desire to be loved’. Amaeru can also be defined as ‘wish to be loved’ and ‘dependency needs’. Various bilingual dictionaries define amae as ‘to lean on a person’s good will’, ‘to depend on another’s affection’, ‘to act lovingly towards (as a much fondled child towards its parents)’, ‘to presume upon’, ‘to take advantage of’; ‘to behave like a spoilt child’, ‘be coquettish’, ‘trespass-on’, ‘take advantage of’, ‘behave in a caressing manner towards a man’; ‘to speak in a coquettish tone’, ‘encroach on (one’s kindness, good nature, etc.)’; ‘presume on another’s love’, ‘coax’, and so on.

The prototype on which the amae concept is based is not difficult to guess. As Doi says “the psychological prototype of amae lies in the psychology of the infant in its relationship to its mother”; not a newborn infant, but an infant who has already realised that its mother exists independently of itself …[A]s its mind develops it gradually realises that itself and its mother are independent existences, and comes to feel the mother as something indispensable to itself, it is the craving for close contact thus developed that constitutes, one might say, amae” (Doi 1981: 74). According to Doi and others, in Japan the kind of relationship based on this prototype provides a model of human relationships in general, especially (though not exclusively) when one person is senior to another.

The following explication is adapted from Wierzbicka (1998):

someone X feels amae (towards Y) at this time:

  • someone X thinks like this at this time (about someone Y):
    • “this someone can do good things for me
    • this someone wants to do good things for me
    • when I am with this someone, nothing bad can happen to me
    • I want to be with this someone”
  • because of this, this someone feels something good at this time
    • like someone can feel when they think like this

The next explication, for the English emotion term ‘happy’ (with the verb ‘to be’), shows how a prototypical cognitive scenario can be incorporated into an explication. The feeling experienced by X is not described directly; rather it is described as LIKE the good feeling experienced by a person who thinks certain prototypical thoughts, cf. Wierzbicka (1999) Goddard and Wierzbicka (2014).

someone X is happy (at this time):

  • someone X thinks like this at this time:
    • “many good things are happening to me as I want
    • I can do many things now as I want
    • this is good”
  • because of this, this someone feels something good at this time
    • like someone can feel when they think like this

This approach to emotion semantics allows a great deal of subtle differentiation between closely related emotions (e.g. ‘happy’, ‘joyful’, ‘pleased’, ‘content’, ‘related’, ‘jubilant’, and so on). To see this, here is a parallel explication for the word ‘contented’. Notice that it follows the same overall structure or “semantic template”:

someone X is contented (at this time):

  • someone X thinks like this at this time:
    • “something good is happening to me now
    • I want this
    • I don’t want anything else now”
  • because of this, this someone feels something good at this time
    • like someone can feel when they think like this

 

Anthropological linguists and ethnographers of communication have long recognised that different speech communities have different “ways of speaking”, not just in the narrowly linguistic sense but also in the norms or conventions of linguistic interaction. “Cultural scripts” are a way of spelling out different “local” conventions of discourse using the metalanguage of universal semantic primes. Using this method, cultural norms can be spelt out with much greater precision than is possible with technical labels such as “direct”, “polite”, “formal” and so on. Because they are phrased in simple and translatable terms, the danger of ethnocentric bias creeping into the very terms of the description is minimised.

Cultural scripts are not intended to provide an account of real life social interactions. Rather they are intended as descriptions of commonly held assumptions about how “people think” about social interaction. Because people bring these assumptions with them into everyday interactions, cultural scripts influence the form taken by particular verbal encounters but they do not in any sense determine individual interactions. Individuals can and do vary in their speech behaviour. The claim of the cultural scripts approach is merely that the scripts form a kind of interpretive background against which individuals position their own acts and those of others.

For example, the script below (cf. Wierzbicka 1994 a) is intended to capture a Japanese cultural norm.

A Japanese cultural script:

  • many people think like this:
  • when something bad happens to someone because I did something,
    • I have to (= can’t not) say something like this to this someone:
      • “I feel something bad because of this”
  • I have to (= can’t not) do something because of this

This represents a hypothesis about a cultural norm which is characteristically (though not exclusively) Japanese. It is linked with the often noted tendency of the Japanese to “apologise” very frequently and in a broad range of situations, but it does so without relying on the culture-bound English speech-act verb apologise. The script is also more accurate and explicit than the English term in not implying any admission that ‘I did something bad to you’, which would be inappropriate for the Japanese ‘apology’. One is expected to perform the speech-act in question whenever one’s action leads someone else to suffer harm or inconvenience, no matter how indirectly. The script is readily translatable into Japanese, and is thus directly accessible to the intuitions of Japanese speakers.

How to Do Soul-Craft with State Tools. On Literacy and AI

Filed under: Uncategorized — E @ 8:15 pm

Widespread literacy… is not a natural baseline but a costly ecological accomplishment. It depends on sustained, large-scale societal investment in both cultivation and maintenance. If that investment falters—or if new modes of communication arise that are less cognitively demanding and more closely aligned with our oral-auditory predispositions—then this hard-won literate ecology can erode rapidly.

In other words, mass literacy is not simply a skill that might fade. It is a complex cognitive adaptation—difficult to build, easy to displace—and, if outcompeted, literacy may once again become the province of a specialized elite.

 

Historically, we accepted literacy’s steep training cost because it offered a unique bundle of symbolic affordances: durable storage, precise retrieval, spatialization, and combinability. These were not luxuries— they were prerequisites for disciplines like law, science, literature, and philosophy.

Now, AI-mediated oral-auditory systems provide many of those same affordances—cloud memory, instant query, spatialized workspaces, speech-to-anything translation—at a fraction of the acquisition cost. We do not need ten years of schooling to learn to ask a language model, by voice, to store or retrieve language.

If new media outperform text on primary utility, ordinary selection pressure may displace literacy from its cultural and cognitive niche. But while these systems may replicate many of the affordances of textuality, their effects may be fundamentally different. And when it comes to literacy, it is precisely the secondary and tertiary effects that carry disproportionate value.

These effects include recursive empathy, long-horizon abstraction, disciplined counterfactual reasoning, interiority, and the capacity to entertain multiple perspectives over time. They emerge slowly, through sustained symbolic engagement. They are difficult to measure, easy to overlook, and prone to erosion when unattended.

To be clear about the mechanism: our society selects for the affordances of a medium—speed, ease, efficiency—not for its effects. And it is the effects of literacy that hold its civilizational value. This is the critical point: those deep cognitive and ethical capacities are not being selected for. They are not easily monetized or optimized. They rarely register on the dashboards that guide decision-making.

The Formal Structure(s) of Analogical Inference. Filosofi al Politecnico delle Marche

Filed under: Uncategorized — E @ 10:18 pm

Recently, Dardashti et al. (Stud Hist Philos Sci Part B Stud Hist Philos Mod Phys 67:1–11, 2019) proposed a Bayesian model for establishing Hawking radiation by analogical inference. In this paper we investigate whether their model would work as a general model for analogical inference. We study how it performs when varying the believed degree of similarity between the source and the target system. We show that there are circumstances in which the degree of confirmation for the hypothesis about the target system obtained by collecting evidence from the source system goes down when increasing the believed degree of similarity between the two systems. We then develop an alternative model in which the direction of the variation of the degree of confirmation always coincides with the direction of the believed degree of similarity. Finally, we argue that the two models capture different types of analogical inference.

Characterization of an adaptive logic

Filed under: Uncategorized — E @ 6:56 pm

The adaptive logic programme aims at developing a type of formal logics (and the connected metatheory) that is especially suited to explicate the many interesting dynamic consequence relations that occur in human reasoning but for which there is no positive test (see the next section). Such consequence relations occur, for example, in inductive reasoning, handling inconsistent data, …

The explication of such consequence relations is realized by the dynamic proof theories of adaptive logics. These proof theories are dynamic in that formulas derived at some stage may not be derived at a later stage, and vice versa.

The programme is application driven. This is one of the reasons why the predicative level is considered extremely important, even if, for many adaptive logics, the basic features of the dynamics are already present at the propositional level. The main applications are taken from the philosophy of science; some also from more pedestrian contexts.

 

Much interesting actual reasoning displays two forms of non-standard dynamics.

  1. An external dynamics: a conclusion may be withdrawn in view of new information. This means that the consequence relation is non-monotonic.
  2. An internal dynamics: a conclusion may be withdrawn in view of the better understanding of the premises provided by a continuation of the reasoning.

While examples of logics displaying the external dynamics are available, logicians did not pay much attention to the internal dynamics. And yet it is very familiar to anyone. Reasoning from one’s convictions, one often derives a consequence that one later rejects, even if one’s convictions were not modified. The point is that humans are unable to see at once all the consequences of a set of premises (in this case, one’s convictions).

 

To clearly understand the two forms of dynamics, it is useful to compare them to the standard forms of logical dynamics. These are common to all reasoning, and well known from usual logics. First consider the standard external dynamics. If we are reasoning (by some logic L) from a set of data Gamma and, at some point in time, are supplied with a supplementary set of data Gamma‘, we are in general able to derive more consequences from that point in time on. Formally: CnL(Gamma\subseteq CnL(GammaunionGamma’). Next consider the standard internal dynamics. Given a set of rules of inference, not all formulas derivable from a set of premises are derivable by a single application of a rule at some stage of a proof. The set of formulas derivable by a single application of a rule monotonically increases as the proof proceeds. A different form of dynamics is related to the fact that humans are unable to see at once all the consequences of a set of premises. As a result, some statements will only be seen to be derivable from the premises after other statements have been derived. The derivability of a statement, however, does not depend on the question whether one sees that it is derivable. So, this form of internal dynamics is related to logical heuristics and to computational aspects, rather than of the logic properly. To be more precise: the formulation of the proof theory is fully independent of it. As we shall see later, the matter is completely different for consequence relations that display an adaptive internal dynamics.

Many consequence relations are undecidable and the predicative versions of nearly all logics are undecidable. If a logic is undecidable but monotonic, there still may be a positive test for derivability. However, if a consequence relation is undecidable and non-monotonic, there can only be a positive test for it in some rather artificial cases. There may at best be a definition of consequence relation in terms of a monotonic logic or in terms of a semantics or in terms of continuations of a proof. And as a logic may be decidable for certain fragments of the language, there may also be criteria for derivability.

 

A general characteristic of the consequence relations mentioned in the previous section is that certain inferences are considered as correct iff certain formulas behave normally. What normality means will depend on the adaptive logic. In an inconsistency-adaptive logic, abnormalities are inconsistencies (possibly of a specific form); in some adaptive logics of induction, abnormalities are negations of generalizations (for example: ~(for allx)(PximpliesQx)). In some (prioritized) adaptive logics, abnormalities (of some priority level) are negations of premises (of that priority) — see the section on Flat and prioritized adaptive logics for an example.

An adaptive logic supposes that all formulas behave normally unless and until proven otherwise. Moreover, if an abnormality occurs, it is considered as local. This means that, even if some formula behaves abnormally, all other formulas are still supposed to behave normally unless and until proven otherwise. We shall see the effect of this in the following section.

While some consequences of a set of premises depend on the normal behaviour of certain formulas, other consequences follow come what may. Thus, an adaptive logic of induction enables one to derive certain generalizations as well as certain ‘predictions’ from a set of premises. To do so, one relies on the supposition that formulas behave normally unless and until proven otherwise. However, the premises also have deductive consequences that follow independently of any normality suppositions.

This naturally leads to seeing an adaptive logic as defined by three elements: the lower limit logic, a set of abnormalities, and an adaptive strategy.
· The lower limit logic determines which consequences hold independently of any presuppositions (or conditions).
· A set of abnormalities, which is characterized by a logical form. For example, the set of abnormalities may contain the existential closure of all formulas of the form A&~A. This logical form may be restricted. For example, the formulas of the form A&~A may be restricted to those in which A is a primitive formula (a schematic letter for sentences, a primitive predicative formula, or an identity). Extending the lower limit logic with an axiom that rules out the occurrence of abnormalities, results in the upper limit logic. In other words, the set of lower limit models that verify no abnormality are the upper limit models. The upper limit logic determines which consequences follow in the normal situation.
· An adaptive strategy. If an abnormality is derivable from the premises (by the lower limit logic), the upper limit logic reduces the premises (or theory) to triviality. However, the adaptive logic still interprets the premises “as normally as possible”. This phrase is ambiguous: there are several ways to do so. The adaptive strategy will pick one specific way to interpret the premises as normally as possible.

This clarifies the way in which adaptive logics adapt themselves to specific premises. The logic interprets the premises in agreement with the lower limit logic and, moreover, as much as possible in agreement with the upper limit logic. If some formulas (premises or lower limit consequences of the premises) are abnormal, the adaptive logic will not add the upper limit consequences of these formulas.

On Having Survived the Academic Moral Philosophy of the 20th Century. Alasdair MacIntyre (1929-2025)

Filed under: Uncategorized — E @ 1:34 pm

I was already fifty-five years old when I discovered that I had become a Thomistic Aristotelian. But I had first encountered Thomism thirty-eight years earlier, as an undergraduate, not in the form of moral philosophy, but in that of a critique of English culture developed by members of the Dominican order. Yet, although impressed by that critique, I hesitated, for those Dominicans made me aware of the philosophical presuppositions of their critique, of a set of Thomistic judgments about the relationships between body, mind, and soul, about passions, will, and intellect, about virtues and reason-informed human actions. And those theses I found problematic. Why so?

From 1945 to 1949 I was an undergraduate student in classics at what was then Queen Mary College in the University of London, reading Greek texts of Plato and Aristotle with my teachers, while also, from 1947 onwards, occasionally attending lectures given by A. J. Ayer or Karl Popper, or by visiting speakers to Ayer’s seminar at University College, such as John Wisdom. Early on I had read Language, Truth and Logic, and Ayer’s student James Thomson introduced me to the Tractatus and to Tarski’s work on truth. Ayer and his students were exemplary in their clarity and rigor and in the philosophical excitement that their debates generated. And I became convinced that the test of any set of philosophical theses, including those defended by Thomists, was whether it could be vindicated. In and through such debates. Yet I also had to learn—and this took a little longer—that in the debates of academic philosophy in the twentieth century no set of theses is ever decisively vindicated.

L’opera letteraria potrebbe essere definita come un’operazione nel linguaggio scritto che coinvolge contemporaneamente più livelli di realtà.

… la letteratura non conosce la realtà ma solo livelli. Se esista la realtà di cui i vari livelli non sono che aspetti parziali, o se esistano solo i livelli, questo la letteratura non può deciderlo. La letteratura conosce la realtà dei livelli e questa è una realtà che conosce forse meglio di quanto non s’arrivi a conoscerla attraverso altri procedimenti conoscitivi. È già molto.

I should have loved biology too

Filed under: Uncategorized — E @ 9:12 pm

One of the stories in the book, the discovery of the gene that caused Huntington’s disease, moved me tremendously when I first read it a few years ago. It’s the perfect example of the amount of effort that goes into a scientific discovery that then ends up as a single sentence in a textbook; in this case, that Huntington’s disease is a hereditary, neurodegenerative disorder caused by a mutation in a single gene.

The story of finding that mutation would make a thrilling movie: a young woman named Nancy Wexler, devastated by the news that her mother has been diagnosed with Huntignton’s and that she and her sister would have a 50-50 chance of getting it, decides to devote her life to solving this medical mystery. Her quest takes her from nursing homes in Los Angeles to interdisciplinary scientific workshops in Boston to stilt villages surrounding Lake Maracaibo in Venezuela. Her decade-long blood and skin sample collection efforts there would create the largest family tree with Huntington’s, leading to the first genetic test for the disease, followed by locating the precise genetic mutation that caused it.

The gene sequence had a strange repeating structure, CAGCAGCAG… continuing for 17 repeats on average (ranging between 10 to 35 normally), encoding a huge protein that’s found in neurons and testicular tissue (its exact function is still not well understood). The mutation that causes HD increases the number of repeats to more than forty – a “molecular stutter” – creating a longer huntingtin protein, which is believed to form abnormally sized clumps when enzymes in neural cells cut it. The more repeats there are, the sooner the symptoms occur and the higher the severity.

Nancy herself opted not to take the genetic test she helped create. “If the test showed I have the gene,” she wrote in 1991, “would I continue to feel the happiness, the passion, the occasional ecstasy I feel now? Is the chance of release from Huntington’s worth the risk of losing joy?”. In 2020, at the age of 74, she revealed that she had Huntington’s. The public acknowledgment was not a surprise for those close to her – for the last decade, they noticed her gait slowly deteriorate, speech slur, and limbs jerk in random directions, the same characteristics she saw in her mother half a century ago, and in the hundreds of Venezuelan patients she tended to ever since.

The more you explore, the more astonishing it gets. Suddenly, you’re surrounded by these facts that stop you in your tracks. Like the fact that there are 20-30 trillion red blood cells in our body, making up roughly 84% of all our cells, and 1.2 million are created in our bone marrow every second. Or the fact that our visual system is predictive, calculating where to move the hand to catch a ball before your visual system has fully registered its trajectory.

One of my favorite ‘sentences that stopped me in my tracks’ comes from Nick Lane’s book, The Vital Question. He starts with carefully explaining that all cells derive their energy from a single type of chemical reaction, the redox reaction, where electrons are transferred from one molecule to another. Rust is a redox reaction: iron donates electrons to oxygen, being oxidized in the process. Same with fire: oxygen (O2) is reduced to water after receiving two electrons (O2-) and then two protons (H2O), balancing the charges, and releasing heat in the process. Respiration — the process that turns our food into energy — does exactly this as well, except that it conserves some of the energy in the form of a molecule called adenosine triphosphate (ATP). Think of ATP as an energy currency, able to be stored or converted back into energy by splitting the molecule into ADP (adenosine diphosphate) and Pi (phospate). And so, he writes, “in the end respiration and burning are equivalent; the slight delay in the middle is what we know as life.”

Sul linguaggio mentale. I ricordi post-ictus di una signora. What my stroke taught me

Filed under: Uncategorized — E @ 2:36 am

At this point I didn’t know much about my brain injury at all. I wasn’t in any pain, so my thoughts about my new condition were unfocused and fleeting. Instead of being occupied by questions about why I was in the hospital and what had happened to me, my mind was engrossed in an entirely different set of perceptions. The smallest of activities would enthrall me. Dressing myself, I was awed by the orbital distance between cloth and flesh. Brushing my teeth, I was enchanted by the stiffness of the bristles and the sponginess of my gums. I also spent an inordinate amount of time looking out the window. My view was mainly of the hospital’s rooftop, with its gray and untextured panels, though I developed a lot of interest in a nearby tree. I could only make out the tops of the branches, but I’d watch this section of needles and boughs intently, fascinated by how the slightest wind would change the shape entirely. It was always and never the same tree.

Very few things disturbed me during this period of time. But even in this formless daydream I remember the moment that most closely resembled real distress. Or, at least, when I became aware of an actual loss.

It must have been midday because the sunlight was falling across my body, and that slat of light emphasized the white nightstand on my left. My parents had filled the shelves inside with clothing, and the nurses made sure there were plenty of liquids for me to drink in there, too. On this day, I noticed that there was a stack of magazines on the nightstand, as well as a book. I am not sure how long they had been there—for all I knew, they could have even predated my arrival—but this was the first time they piqued my interest.

The high gloss of the magazine cover felt wet in my hands. And as I opened it up, I was instantly bombarded with photos of red carpet parades and illustrated makeup tips, a circus of color and distraction. I couldn’t linger anywhere. It felt as if the magazine were shouting at me. Closing it was a relief.

I turned to the book. It was a novel by Agatha Christie, something I had probably read many years earlier. I opened to Chapter One and flipped slowly and evenly through the first few pages, a motion that seemed to come naturally to me. But on the third page, I stopped. I returned to the first page and started again. Slower this time. Much slower. My eyes focused and refocused in the bright sunlight, but I continued to only see the black, blocked shapes where words used to be.

Thinking about it now, I don’t know how I could be so certain that it was an Agatha Christie novel, especially since this was the very moment I became aware I couldn’t read anymore. With this simultaneously familiar and unfamiliar book in my hands, I first took in the actual loss of words. For my entire life, language had been at the forefront of every personal or professional achievement, and very few things had brought me as much joy and purpose. If I had ever been warned that I might be robbed of my ability to read, even for a limited amount of time, it would have been a devastation too cruel to bear. Or so I would have thought. But a day did come when I couldn’t read the book in front of me, when paragraphs appeared to be nothing more than senseless jumbles, and the way I actually processed this massive loss was surprisingly mild. The knowledge of the failure was jarring, without a doubt, but was there any misery or angst? No. My reaction was much less sharp. A vague sense of disappointment swept through me, but then … my inability to use words in this way just felt like transient information. Now that the ability was gone, I could no longer think of how or why it should have any influence on my life whatsoever.

My trouble with spoken language was mirrored in my written language. I discovered as I progressed in my sessions with Anne that I had not completely forgotten the alphabet, but I had forgotten its order. If I isolated single letters at a time, I could still identify them on a page. It took a lot of guidance from Anne, but with her by my side, I could slowly sound out these letters, occasionally creating a very fragile word. Anne noted: “There are frequent errors reading aloud, especially words with irregular pronunciations, and Lauren finds it difficult to know if she is correct or not.” So, while I had not lost my ability to read entirely, “reading” in this new iteration of my life involved a razor-sharp focus, accommodating only a word at a time. I also wasn’t able to know my own accuracy without someone else’s support. I would slowly sound out a word, but it took so long that when I went on to tackle the next one, I often would forget what I had just read. Perhaps that was what had happened with the Agatha Christie book I had attempted to read by myself. I had been expecting the language on the page to behave the way it used to, and when it didn’t, the whole picture crumbled in front of me. Words could be approachable in small, isolated units. But a full sentence? That was beyond imagining.

The rupture had originated on the middle cerebral artery in the left hemisphere of my brain, bleeding into the Sylvian fissures and my left basal ganglia. This cerebral artery supplies the blood for the two language centers of the brain—Broca’s area and Wernicke’s area. The basal ganglia are usually associated with motor control, but they also affect habits, cognition, and emotion. Some basal injuries can blunt emotional awareness and slow “goal-directed” activity. With such a wide range of influences, the alterations to the basal ganglia were probably affecting me in many ways at the time, but after the rupture, it was my faltering language that was my most visible symptom.

As ‘Bot’ Students Continue to Flood In, Community Colleges Struggle to Respond

Filed under: Uncategorized — E @ 3:33 pm

Community colleges first started seeing bots managed by fraud rings invade classes around 2021. Those bots seem to generally be real people managing networks of fake student aliases. The more they manage, the more financial aid money they can potentially steal.

Four years later, there are no clear signs it’s slowing down. During 2024 alone, fraudulent students at California community colleges swindled more than $11 million in state and federal financial aid dollars — more than double what was stolen the year prior.

Last year, the state chancellor’s office estimated 25 percent of community college applicants were bots.

Despite the eye-popping sum, state leaders are quick to point out that amounts to a fraction of the around $3.2 billion combined state and federal financial aid disbursed last year. But for many community college teachers, particularly those who teach online courses, the influx of bot students has changed what it means to be a teacher, said Eric Maag, who has taught at Southwestern for 21 years.

“We didn’t use to have to decide if our students were human, they were all people. But now there’s this skepticism because a growing number of the people we’re teaching are not real. We’re having to have these conversations with students, like, ‘Are you real? Is your work real?’” Maag said. “It’s really complicated, the relationship between the teacher and the student in almost like a fundamental way.”

Those teacher-led investigations have become more difficult over the years, professors say. While some bots simply don’t submit classwork and hope they can skate by, they also frequently use AI programs to generate classwork that they then submit. Determining whether a student is a bot can be a confusing task. After all, even real students use AI to do some good old-fashioned cheating in classes.

That mad bot-powered dash for enrollment has left some students unable to register for the classes they need. It has also given rise to a sort of whisper network, where professors recommend students reference them by name when trying to get added to other classes.

Kevin Alston, a business professor who has taught at Southwestern for nearly 20 years, has stumbled across even more troubling incidents. During a prior semester, he actually called some of the students who were enrolled in his classes but had not submitted any classwork.

“One student said ‘I’m not in your class. I’m not even in the state of California anymore’” Alston recalled.

The student told him they had been enrolled in his class two years ago but had since moved on to a four-year university out of state.

“I said, ‘Oh, then the robots have grabbed your student ID and your name and re-enrolled you at Southwestern College. Now they’re collecting financial aid under your name,’” Alston said.

The California Community College system has put more resources toward detecting fraudulent students, partnering with a handful of tech companies, like ID.me to authenticate students. But that still hasn’t stopped the bots. As of March, scammers had already swindled nearly $4 million in federal and state financial aid.
