No poco se habrá meditado acerca del poema “Todtnauberg” de Paul Celan (1967), publicado en Lichtzwang (1970). Poco o casi nada, en cambio, acerca de su “respuesta poética” (si cabe la expresión) por parte de Martin Heidegger: “Vorwort” (1971). En lo que sigue nos limitamos a puntear algunas de las circunstancias tal vez más marcantes de esta suerte de “correspondencia” heideggeriana y eventual “familiar” (y tal vez inmortal) micro-bolero. Palabras clave: Todtnauberg - Paul Celan - Vorwort - Martin Heidegger - (...) grotesco. (shrink)

In this paper I examine the notion of ‘artifact’ and related notions in the dominant version of extended cognition theory grounded on extended functionalism. Although the term is ubiquitous in the literature, it is far from clear what ECT means by it. How are artifacts conceptualized in ECT? Is ‘artifact’ a meaningful and useful category for ECT? If the answer to the previous question is negative, should we worry? Is it important for ECT to have a coherent theory of artifacts? (...) And what are the demands and constraints that ECT imposes on this theory? I distinguish between two aspects of ECT, one narrow, aligned with extended functionalism ; and one broad or pluralistic, in which EF is combined with other theoretical resources in the context of diverse research programs. I begin by determining the problems in conceptualizing artifacts from EF. Then I address the question of why a concept of artifact may be relevant to ECT. Next, I examine the efforts of Richard Heersmink to combine ECT with dominant theories of artifacts in the philosophy of technology. I argue that both approaches fail to yield a meaningful notion of artifact, let alone one of ‘cognitive’ artifact. Finally, I argue that narrow ECT places rather strong constraints on a theory of artifacts, since it locates the specificity of ‘artifact’ in material aspects of realization that are, by definition, outside its theoretical purview. I examine, then discard, the possibility that a materialist and objectivist theory of artifacts may be of help. And finally I briefly explore some ways in which a broad, pluralistic ECT may address some of these shortcomings. (shrink)

The idea of inclusive collective decision-making is important in establishing democratic legitimacy, but it fails when citizens are excluded. Stated-preference methods of valuation, which are commonly used in economics, have been criticised because the principle of willingness to pay may exclude low-income earners who do not have the capacity to pay. Deliberative valuation has been advocated as a way to overcome this problem, but deliberation may also be exclusive. In this review, two deliberative valuation frameworks are compared. The first is (...) grounded on the idea of rational discourse that emphasises argument at the expense of other communicative strategies. It seeks to secure inclusion through procedural rules and prerequisites, but fails to address the underlying democratic limitation of argumentation. The second does not rely on the distinction between rational and rhetorical speech, and therefore admits alternative forms of communication. This approach recognises differences in the communicative capacities and practices of those who take part in deliberation, and so is better equipped to improve, though not to guarantee, inclusion.

In this paper I argue that the search for explainable models and interpretable decisions in AI must be reformulated in terms of the broader project of offering a pragmatic and naturalistic account of understanding in AI. Intuitively, the purpose of providing an explanation of a model or a decision is to make it understandable to its stakeholders. But without a previous grasp of what it means to say that an agent understands a model or a decision, the explanatory strategies will (...) lack a well-defined goal. Aside from providing a clearer objective for XAI, focusing on understanding also allows us to relax the factivity condition on explanation, which is impossible to fulfill in many machine learning models, and to focus instead on the pragmatic conditions that determine the best fit between a model and the methods and devices deployed to understand it. After an examination of the different types of understanding discussed in the philosophical and psychological literature, I conclude that interpretative or approximation models not only provide the best way to achieve the objectual understanding of a machine learning model, but are also a necessary condition to achieve post hoc interpretability. This conclusion is partly based on the shortcomings of the purely functionalist approach to post hoc interpretability that seems to be predominant in most recent literature. (shrink)

Plagiarism is a serious, yet widespread type of research misconduct, and is often neglected in developing countries. Despite its far-reaching implications, plagiarism is poorly acknowledged and discussed in the academic setting, and insufficient evidence exists in Latin America and developing countries to inform the development of preventive strategies. In this context, we present a longitudinal case study of seven instances of plagiarism and cheating arising in four consecutive classes of an Epidemiology Masters program in Lima, Peru, and describes the implementation (...) and outcomes of a multifaceted, “zero-tolerance” policy aimed at introducing research integrity. Two cases involved cheating in graded assignments, and five cases correspond to plagiarism in the thesis protocol. Cases revealed poor awareness of high tolerance to plagiarism, poor academic performance, and widespread writing deficiencies, compensated with patchwriting and copy-pasting. Depending on the events’ severity, penalties included course failure and separation from the program. Students at fault did not engage in further plagiarism. Between 2011 and 2013, the Masters program sequentially introduced a preventive policy consisting of: intensified research integrity and scientific writing education, a stepwise, cumulative writing process; honor codes; active search for plagiarism in all academic products; and a “zero-tolerance” policy in response to documented cases. No cases were detected in 2014. In conclusion, plagiarism seems to be widespread in resource-limited settings and a greater response with educational and zero-tolerance components is needed to prevent it. (shrink)

En su reflexión, Andrés Monares se hace las preguntas de fondo respecto de los argumentos éticos, económicos e incluso religiosos que justifican el rechazo al neoliberalismo. Recurriendo a la pregunta de ¿quién puede ser neoliberal?, recorre los diferentes aspectos de esta doctrina, adentrándose en sus orígenes como parte de una teología protestante, y su posterior transformación en ideología económica y social.

Large cardinals arising from the existence of arbitrarily long end elementary extension chains over models of set theory are studied here. In particular, we show that the large cardinals obtained in this fashion (`unfoldable cardinals') lie in the boundary of the propositions consistent with `V = L' and the existence of 0 ♯ . We also provide an `embedding characterisation' of the unfoldable cardinals and study their preservation and destruction by various forcing constructions.

We study versions of limit models adapted to the context of metric abstract elementary classes. Under categoricity and superstability-like assumptions, we generalize some theorems from 7, 15-17. We prove criteria for existence and uniqueness of limit models in the metric context.

Este artículo interroga críticamente la pretensión de Jacques Rancière de pensar la política sin referencia a espacios sociales ni a las relaciones de poder que tienen lugar en ellos. En este texto se pretende mostrar que estas descripciones y cartografías de los espacios sociales operan como presupuestos ocultos de la teoría rancieriana, a pesar de ser rechazadas por el mismo filósofo francés como elementos fundamentales de la reflexión sobre la política. El artículo se acerca en la primera parte a las (...) objeciones del pensador francés en contra de las teorías que derivan la naturaleza del conflicto político de la comprensión de los conflictos sociales, como el marxismo. En la segunda parte se muestra que el concepto rancieriano de la política, sin referirse a descripciones sociológicas de la sociedad como las del marxismo, caería en contradicciones internas a la hora de vincular la política con la emancipación, pues la figura de la actualización de la igualdad no basta para definir el carácter emancipatorio la irrupción política.

This paper presents a method to compute a posteriori probability intervals when the initial conditional information is also given with probability intervals. The right way to make an exact computation is with the associated convex set of probabilities. Probability trees are used to represent these initial conditional convex sets because they greatly save the space required. This paper proposes a simulated annealing algorithm, which uses probability trees to represent the convex sets in order to compute the a posteriori intervals.

As society advances, the educational system remains linked to the traditional model focused on the transmission of information and must adapt to new times and new profile of students, with the students and learning centered education. Active pedagogies developed during the 20th century become a fundamental reference point for the implementation of education competencies.

We study whether the probabilistic postulate could be derived from basic principles. Through the analysis of the Strong Law of Large Numbers and its formulation in quantum mechanics, we show, contrary to the claim of the many-worlds interpretation defenders and the arguments of some other authors, the impossibility of obtaining the probabilistic postulate by means of the frequency analysis of an ensemble of infinite copies of a single system. It is shown, though, how the standard form of the probability as (...) the square of the scalar product follows from Gleason's theorem. (shrink)

One of the strongest defences of free speech holds that autonomy requires the protection of speech. In this paper I examine five conditions that autonomy must satisfy. I survey recent research in social psychology regarding automatic behaviour, and a challenge to autonomy is articulated. I argue that a plausible strategy for neutralising some of the autonomy-threatening automatic responses consists in avoiding the exposure to the environmental features that trigger them. If this is so, we can good autonomy-based pro tanto reasons (...) for controlling exposure to certain forms of speech. (shrink)

We study notions of independence appropriate for a stability theory of metric abstract elementary classes (for short, MAECs). We build on previous notions used in the discrete case, and adapt definitions to the metric case. In particular, we study notions that behave well under superstability‐like assumptions. Also, under uniqueness of limit models, we study domination, orthogonality and parallelism of Galois types in MAECs.

The discovery-justification distinction stands as a pivotal issue within 20th-century philosophy of science. It subtly underpins many foundational topics and concepts pertinent to our comprehension of knowledge. Thomas Kuhn's contributions are indispensable in this regard, with his critiques playing a pivotal role in shaping both his initial model of scientific progress and its subsequent revisions. Kuhn addressed this dichotomy head-on in the first of his Thalheimer Lectures, presented in 1984. In this paper, we revisit Pablo Melogno's (2019) examination of Kuhn's (...) engagement with this theme. Concurring with Melogno, our analysis extends his interpretation by exploring Larry Laudan's objections to certain research programs focused on a logic of discovery. We further scrutinize specific assumptions about discovery heuristics that have been misinterpreted within Laudan's methodological framework, particularly the one stemming from Herbert Simon's pioneering work. By synthesizing these perspectives, we aim to set up a preliminary framework for a more refined understanding of how history and philosophy of science inform the epistemic practices of agents operating with bounded rationality.

Tanto le debo a Lelio Fernández... La enumeración incompleta de esa deuda me lleva a mis años de filosofía en Cali, Colombia, de 1985 a 1989. En sus clases, gracias al placer por la lectura en detalle, Lelio contagiaba con la emoción de querer entender; lograba conectarnos con la historia de la cultura sin desplegar ninguna ayuda “audio-visual”; transmitía su deseo de estar siempre saboreando las obras de Baruch Spinoza (1632‒1677) y de Jorge Luis Borges (1899‒1986); se limitaba a sentarse (...) detrás de un escritorio en los salones de clase, hablando bajo y con precisión y con emoción contenida; era necesario llegar casi dos horas antes a ese salón de clase en la Universidad del Valle para no estar obligado a medio-escuchar sus pensamientos en el corredor; me ayudó en la traducción de los apartes en latín, y aún no publicados en castellano, que Umberto Eco (1932‒2016) incluyó en El nombre de la rosa; y tradujo al castellano, con Jean-Paul Margot, el Breve tratado de la reforma del entendimiento también de Spinoza.

The origin of Paraconsistent Logic is closely related with the argument that from the assertion of two mutually contradictory statements any other statement can be deduced, which can be referred to as ex contradict!one sequitur quodlibet (ECSQ). Despite its medieval origin, only in the 1930s did it become the main reason for the unfeasibility of having contradictions in a deductive system. The purpose of this paper is to study what happened before: from Principia Mathematica to that time, when it became (...) well established. The main historical claims that I am going to advance are the following: the first explicit use of ECSQ as the main argument for supporting the necessity of excluding any contradiction from deductive systems is to be found in the first edition (1928) of the book Grundzüge der theoretischen Logik by Hilbert and Ackermann. At the end, I will suggest that the aim of the 20th century usage of ECSQ was to change from the centuries long philosophical discussion about contradictions to a more "technical" one. But with Paraconsistent Logic viewed as a technical solution to this restriction, the philosophical problem revives, but now with an improved understanding of it at one's disposal. (shrink)

Moral motivation refers to the psychological causes that motivate or explain moral action. Moral action refers to action that complies with the requirements of morality. In this essay, I lay out alternative views on moral motivation, giving particular attention the way each view conceives of the explanatory link between practical reasoning and moral conduct. In trying to understand this link, philosophers look to moral judgment. The main rival accounts of the relationship between practical reasoning, moral judgment, and moral motivation can (...) be distinguished according to the way in which they respond to two questions: (1) Can a cognitive (i.e., belief-like) state produce in an agent a motivation at time t, without being accompanied by an affective (i.e., emotional or desire-like) state which exists prior to t? (2) Are moral judgments cognitive states or affective states? -/- I shall defend the Humean theory of motivation, or HTM, as the best account of moral motivation. HTM is often called the belief-desire model of action because it explains behavior by citing a combination of a desire for some end and a belief that a certain action is a means to satisfying that desire. The Humean answer to the first question above is that any process of practical reasoning which generates a motivation is necessarily linked to a non-cognitive state. Regarding the second question, Humeans are split between cognitivists and non-cognitivists. Anti-Humeans, on the other hand, hold that moral judgments express cognitive states, and that cognitive states can independently produce motivations via practical reasoning. -/- I offer two arguments in favor of HTM. First, I suggest that Humeanism meets one criterion of theory choice better than anti-Humeanism. This is the continuity constraint. Given that humans and non-humans evolved common ancestors, the continuity constraint advises us to prefer an account of human psychology which can explain how complex human traits evolved from simpler antecedents resembling the traits of non-human animals. Non-human primates, in particular, are capable of acting altruistically toward con-specifics. Altruistic behavior in primates can shed light on an evolutionary precursor to moral action in humans, since morally significant action often involves altruism. I maintain that a Humean theory of motivation offers the best explanation of altruistic behavior in non-human primates. Therefore, by the continuity constraint, HTM should be the preferred model of the psychological mechanisms underlying human moral motivation, unless empirical evidence strongly suggests otherwise. -/- To ward off the objection that anti-Humeanism is warranted due to the vast differences between humans and non-human primates, I offer a second argument for HTM. This is an argument from a criterion of theory choice called Morgan’s Canon. Morgan’s Canon is a standard of theoretical parsimony according to which a psychological mechanism should be attributed to an organism only if it’s the sole mechanism which can cause some behavior. I argue that HTM meets this criterion much better than anti-Humeanism. This is because the special psychological mechanisms which anti-Humeans postulate to explain moral action are not the sole mechanisms which could produce such action. Rather, the Humean belief-desire model could easily be recruited to explain moral action, as well as a broad variety of non-moral actions. (shrink)

Explanation and understanding are intimately connected notions, but the nature of that connection has generally not been considered a topic worthy of serious philosophical investigation. Most authors have avoided making reference to the notion of understanding in their accounts of explanation because they fear that any mention of the epistemic states of the individuals involved compromises the objectivity of explanation. Understanding is a pragmatic notion, they argue, and pragmatics should be kept at a safe distance from the universal features of (...) explanation. My main contention in this dissertation is that there is a sense in which it is meaningful and useful to talk about objective understanding, and that to characterize this notion it is necessary to formulate an account of objective explanation that makes reference to the beliefs and epistemic goals of the participants in a cognitive enterprise. ;My account of explanation is based on the belief-doubt model of inquiry first proposed by Peirce. Using the tools provided by decision theory, and the models of belief revision developed by Isaac Levi and by Alchourron, Gardenfors, and Makinson, I analyze the objective and pragmatic conditions that a piece of information must fulfill to be both explanatory and epistemically useful to an inquiring agent. The objective basis for an explanation is provided by the relation of probabilistic relevance that the fact described by the explanans bares to the fact described by the explanandum. But an explanation is much more than its foundation. As an epistemological notion, a potential explanation can only be a bona fide explanation if it becomes part of inquiry, that is, if an agent or a group of agents can see any value in it for their cognitive purposes. I provide a way to evaluate an explanation in terms of its credibility, its content, and its explanatory value. I argue that although an objective measure of the credibility and content of an explanation can be established, in many cases a complete determination of its explanatory value will ultimately depend on the interests and goals of the individual inquirers.

Resumen: Una de las formas más comunes y menos estudiadas de parcialidad judicial subjetiva es la disminución de la credibilidad otorgada a un testigo debido a un prejuicio identitario implícito del agente judicial. En la epistemología social, este fenómeno ha sido estudiado bajo la rúbrica de la injusticia testimonial. En este ensayo mostramos que para determinar la ocurrencia de un caso de injusticia testimonial en el derecho se deben cumplir tres condiciones que son imposibles de verificar empíricamente y que están (...) basadas en presupuestos psicológicos que han sido puestos en duda en años recientes. Sin la posibilidad de verificar estas condiciones, estamos frente a un tipo de parcialidad judicial indetectable. En su lugar, ofrecemos una nueva forma de entender la injusticia testimonial en el derecho como un fenómeno más general que describe una tendencia comportamental prejuiciosa recurrente por parte de un agente judicial. Entendida de este modo, la injusticia testimonial es completamente verificable. -/- Abstract: One of the most common and least studied forms of subjective judicial partiality is the credibility deficit suffered by a witness due to an implicit identity prejudice in a judicial agent. Social epistemologists have studied this form of partiality under the rubric, “testimonial injustice.” In this essay we argue that to verify the occurrence of a singular instance of testimonial injustice in law three facts must be established, none of which can be established with any degree of confidence. Furthermore, all of them are based on psychological suppositions that have been recently discredited. Without the possibility of establishing these facts, we end up with an undetectable form of subjective judicial partiality. In its place, we offer a new way of understanding testimonial injustice in law as a general phenomenon that describes a recurrent pattern of prejudiced behavior in a judicial agent. Under this characterization, testimonial injustice becomes empirically verifiable. (shrink)

This paper offers some insights and clarifications of the paramount role that Mexico has had in the forging of first-order cybernetics. Our account starts with Arturo Rosenblueth as a key intellectual figure in the foundation and formation of the field. After revisiting a historical context of people and places, we proceed to a cultural and media archeological investigation that helps us obtain new insights into the ongoing effort to intertwine the complex intellectual networks across different countries in Latin America, North (...) America, and Europe. We then present cases and first-hand interviews to discuss the legacy of cybernetics in Mexico around institutions where Rosenblueth was affiliated, mainly the Institute of Cardiology and, later on, the CINVESTAV at the Instituto Politécnico Nacional. We claim that subjective affinities are as important as common scientific goals to establish and keep connections alive, necessary to the development of a research field. As the active compound in spicy peppers, capsaicin represents a local component to the definition of cybernetics. Ultimately, the paper aims to contribute to the research on the importance of cybernetics in Latin America. (shrink)

Historiographical accounts typically place the formulation of the first embryological theory of the evolutionary origin of vertebrates after the publication of Darwin’s On the Origin of Species. However, the French naturalist Étienne Geoffroy Saint-Hilaire developed an embryological evolutionary model in the 1820s that followed the Lamarckian theory. Geoffroy was the first to establish a direct embryological relationship between vertebrates and invertebrates. This idea was not forgotten, and the embryologists Anton Dohrn and Carl Semper subsequently updated it in their annelid theory (...) as part of a debate about the origin of vertebrates that occurred during the latter part of the nineteenth century. This paper reviews the traditional historiography, analyzing and integrating Geoffroy’s model into the current body of ideas. (shrink)

Aim: The present work proposes the study of the neuromotor activity of the masseter-jaw-tongue articulation during diadochokinetic exercising to establish functional statistical relationships between surface Electromyography, 3D Accelerometry, and acoustic features extracted from the speech signal, with the aim of characterizing Hypokinetic Dysarthria. A database of multi-trait signals of recordings from an age-matched control and PD participants are used in the experimental study. Hypothesis: The main assumption is that information between sEMG and 3D acceleration, and acoustic features may be quantified (...) using linear regression methods. Methods: Recordings from a cohort of eight age-matched control participants and eight PD participants were collected during the utterance of a diadochokinetic exercise. The dynamic and acoustic absolute kinematic velocities produced during the exercises were estimated by acoustic filter inversion and numerical integration and differentiation of the speech signal. The amplitude distributions of the absolute kinematic and acoustic velocities are estimated to allow comparisons in terms of Mutual Information. Results: The regression results show the relationships between sEMG and dynamic and acoustic estimates. The projection methodology may help in understanding the basic neuromotor muscle activity regarding neurodegenerative speech in remote monitoring neuromotor and neurocognitive diseases using speech as the vehicular tool, and in the study of other speech-related disorders. The study also showed strong and significant cross-correlations between articulation kinematics, both for the control and the PD cohorts. The absolute kinematic variables presents an observable difference for the PD participants compared to the control group. Conclusion: Kinematic distributions derived from acoustic analysis may be useful biomarkers toward characterizing HD in neuromotor disorders providing new insights into PD. (shrink)
