Un atlas zoopolítico es lo que pretende tener aquí lugar. Un atlas en el sentido en que cada pequeño tratado de los cincuenta y dos que configuran el libro se presenta en la forma de un retrato donde el pensamiento, entre sus pensadores, se aplica en el esfuerzo de hacerse cargo de la presencia animal sin renunciar a la diferencia humana, y en que, entre todos ellos, se delinea en todas sus valoraciones posibles esta nueva presencia del animal entre nosotros. (...) Retrato con animal. Prefacio. Pablo Perera Velamazán es escritor, además de filósofo e historiador del arte. Esta triple condición –y alguna otra (profesor, traductor)- le han permitido entrar en el círculo de los que escriben siempre de los que no saben y le ha impedido, también formar parte de ninguna empresa concreta, salvo la del precipicio del pensamiento en la singularidad que se resiste a los nombres. Allí suelen estar acompañado de niños y animales, de ángeles como muñecos, pero allí también se pueden encontrar a cualquiera. Buen compañero de viaje de invierno. (shrink)

Animals navigate through three-dimensional environments, but we argue that the way they encode three-dimensional spatial information is shaped by how they use the vertical component of space. We agree with Jeffery et al. that the representation of three-dimensional space in vertebrates is probably bicoded (with separation of the plane of locomotion and its orthogonal axis), but we believe that their suggestion that the vertical axis is stored (that is, not containing distance or direction metrics usable for novel computations) is unlikely, (...) and as yet unsupported. We describe potential experimental protocols that could clarify these differences in opinion empirically. (shrink)

We say that a sentence A is a permissive consequence of a set X of premises whenever, if all the premises of X hold up to some standard, then A holds to some weaker standard. In this paper, we focus on a three-valued version of this notion, which we call strict-to-tolerant consequence, and discuss its fruitfulness toward a unified treatment of the paradoxes of vagueness and self-referential truth. For vagueness, st-consequence supports the principle of tolerance; for truth, it supports the (...) requisite of transparency. Permissive consequence is non-transitive, however, but this feature is argued to be an essential component to the understanding of paradoxical reasoning in cases involving vagueness or self-reference.

How should political power and influence be allocated in democratic systems? That is, roughly, the core of the boundary problem in democratic theory. As of late, some authors have begun paying increased attention to the methodological aspects of this dispute. This paper attempts to make a twofold contribution to this ‘methodological turn’. On the one hand, it identifies and analyzes five desiderata of a successful principle of democratic inclusion. Any such principle, I argue, must be grounded in a clearly identifiable (...) set of values, must provide a clear standard of inclusion, must specify the relevant modalities of inclusion, must provide sound bridging principles, and must be extensionally adequate. In the first half of the paper, these desiderata are developed and critically scrutinized. On the other hand, I also extract three lessons from the previous discussion. First, that a unique answer to the boundary problem (i.e. one grounded in one single principle) is unlikely. Second, that a satisfactory answer to the boundary problem need not necessarily appeal, as some have argued, to distinctively democratic values. And third, that intuitions about political exclusion (i.e. those requiring or permitting the exclusion of some individuals) should be treated with special caution. (shrink)

In this chapter we use methods of corpus linguistics to investigate the ways in which mathematicians describe their work as explanatory in their research papers. We analyse use of the words explain/explanation (and various related words and expressions) in a large corpus of texts containing research papers in mathematics and in physical sciences, comparing this with their use in corpora of general, day-to-day English. We find that although mathematicians do use this family of words, such use is considerably less prevalent (...) in mathematics papers than in physics papers or in general English. Furthermore, we find that the proportion with which mathematicians use expressions related to ‘explaining why’ and ‘explaining how’ is significantly different to the equivalent proportion in physics and in general English. We discuss possible accounts for these differences. (shrink)

“But surely if it's not irrational, it can’t be OCD!” my friend exclaimed, when I told them about the paper Carolina Flores and Brent Kious provided their excellent comments for. In all fairness, my friend is not working in philosophy, or psychiatry, or in psychology. Still, I take their sentiment to be expressive of a widely held view: if you have a certain mental illness, then you must be irrational. Conversely, rationality guarantees mental health; the sane life is the rational (...) life. -/- In my paper, I attempted to complicate this picture. My main line of thought was that if the sane life is the rational life, we do not have a good conception of rationality yet. For, our best theories of rationality fail to capture what is going wrong in some cases of obsessive-compulsive disorder (OCD). Addressing the criticisms raised by my commentators will allow me to clear up some misunderstandings and sketch avenues for further work. (shrink)

The main purpose of these introductory remarks is to give the reader a sense of Philip Rossi’s philosophical project and its importance. I will then advance an interpretation of what motivates Kant’s commitment to community, and, on its basis, object to Rossi’s views on radical evil –a point which affects how one should conceive the moral vocation of humanity and the role that politics and religion play within it. My reconstruction concludes with a sketch of how the five contributions to (...) this Symposium fit together and deepen our understanding of Rossi’s overall project. (shrink)

In a recent paper, Barrio, Tajer and Rosenblatt establish a correspondence between metainferences holding in the strict-tolerant logic of transparent truth ST+ and inferences holding in the logic of paradox LP+. They argue that LP+ is ST+’s external logic and they question whether ST+’s solution to the semantic paradoxes is fundamentally different from LP+’s. Here we establish that by parity of reasoning, ST+ can be related to LP+’s dual logic K3+. We clarify the distinction between internal and external logic and (...) argue that while ST+’s nonclassicality can be granted, its self-dual character does not tie it to LP+ more closely than to K3+.

Frost's article advocates for universal models of reading and critiques recent models that concentrate in what has been described as “cracking the orthographic code.” Although the challenge to develop models that can account for word recognition beyond Indo-European languages is welcomed, we argue that reading models should also be constrained by general principles of visual processing and object recognition.

Supervaluationism is a well known theory of vagueness. Subvaluationism is a less well known theory of vagueness. But these theories cannot be taken apart, for they are in a relation of duality that can be made precise. This paper provides an introduction to the subvaluationist theory of vagueness in connection to its dual, supervaluationism. A survey on the supervaluationist theory can be found in the Compass paper of Keefe (2008); our presentation of the theory in this paper will be short (...) to get rapidly into the logical issues. This paper is relatively self-contained. A modest background on propositional modal logic is, though not strictly necessary, advisable. The reader might find useful the Compass papers Kracht (2011) and Negri (2011) (though these papers cover issues of more complexity than what is demanded to follow this paper). (shrink)

Michel Janssen and Harvey Brown have driven a prominent recent debate concerning the direction of an alleged arrow of explanation between Minkowski spacetime and Lorentz invariance of dynamical laws in special relativity. In this article, I critically assess this controversy with the aim of clarifying the explanatory foundations of the theory. First, I show that two assumptions shared by the parties—that the dispute is independent of issues concerning spacetime ontology, and that there is an urgent need for a constructive interpretation (...) of special relativity—are problematic and negatively affect the debate. Second, I argue that the whole discussion relies on a misleading conception of the link between Minkowski spacetime structure and Lorentz invari-ance, a misconception that in turn sheds more shadows than light on our understand-ing of the explanatory nature and power of Einstein’s theory. I state that the arrow connecting Lorentz invariance and Minkowski spacetime is not explanatory and uni-directional, but analytic and bidirectional, and that this analytic arrow grounds the chronogeometric explanations of physical phenomena that special relativity offers.

To what degree can language be acquired from linguistic input alone? This question has vexed scholars for millennia and is still a major focus of debate in the cognitive science of language. The complexity of human language has hampered progress because studies of language–especially those involving computational modeling–have only been able to deal with small fragments of our linguistic skills. We suggest that the most recent generation of Large Language Models (LLMs) might finally provide the computational tools to determine empirically (...) how much of the human language ability can be acquired from linguistic experience. LLMs are sophisticated deep learning architectures trained on vast amounts of natural language data, enabling them to perform an impressive range of linguistic tasks. We argue that, despite their clear semantic and pragmatic limitations, LLMs have already demonstrated that human-like grammatical language can be acquired without the need for a built-in grammar. Thus, while there is still much to learn about how humans acquire and use language, LLMs provide full-fledged computational models for cognitive scientists to empirically evaluate just how far statistical learning might take us in explaining the full complexity of human language.

In this paper we investigate a semantics for first-order logic originally proposed by R. van Rooij to account for the idea that vague predicates are tolerant, that is, for the principle that if x is P, then y should be P whenever y is similar enough to x. The semantics, which makes use of indifference relations to model similarity, rests on the interaction of three notions of truth: the classical notion, and two dual notions simultaneously defined in terms of it, (...) which we call tolerant truth and strict truth. We characterize the space of consequence relations definable in terms of those and discuss the kind of solution this gives to the sorites paradox. We discuss some applications of the framework to the pragmatics and psycholinguistics of vague predicates, in particular regarding judgments about borderline cases. (shrink)

In a previous paper (see ‘Tolerant, Classical, Strict’, henceforth TCS) we investigated a semantic framework to deal with the idea that vague predicates are tolerant, namely that small changes do not affect the applicability of a vague predicate even if large changes do. Our approach there rests on two main ideas. First, given a classical extension of a predicate, we can define a strict and a tolerant extension depending on an indifference relation associated to that predicate. Second, we can use (...) these notions of satisfaction to define mixed consequence relations that capture non-transitive tolerant reasoning. Although we gave some empirical motivation for the use of strict and tolerant extensions, making use of them commits us to the view that sentences of the form ‘ p∨¬p ’ and ‘ p∧¬p ’ are not automatically valid or unsatisfiable, respectively. Some philosophers might take this commitment as a negative outcome of our previous proposal. We think, however, that the general ideas underlying our previous approach to vagueness can be implemented in a variety of ways. This paper explores the possibility of defining mixed notions of consequence in the more classical super/sub-valuationist setting and examines to what extent any of these notions captures non-transitive tolerant reasoning. (shrink)

One way in which we might approach the challenge posed by the Sorites Paradox is considering that Sorites-susceptible predicates have several candidate extensions, or several ways in which these expressions can be made precise. For example, a candidate extension for the predicate ‘is a baby’ is the set of humans of less than two years, but also the set of those less than two years and one second, and of those less than two years and two seconds. In this chapter (...) we present and discuss two theories for vague predicates based on this idea: supervaluationism and subvaluationism. The chapter is structured in three parts. The first presents the super- and subvaluationist theories: their similarities and differences in the semantics, the resulting logics with their most characteristic features. The second reviews the super- and subvaluationist solutions to the Sorites Paradox and provides discussion on several controversies surrounding these theories. The third part introduces proof procedures for s’valuationist logics. (shrink)

This paper presents and defends a way to add a transparent truth predicate to classical logic, such that and A are everywhere intersubstitutable, where all T-biconditionals hold, and where truth can be made compositional. A key feature of our framework, called STTT (for Strict-Tolerant Transparent Truth), is that it supports a non-transitive relation of consequence. At the same time, it can be seen that the only failures of transitivity STTT allows for arise in paradoxical cases.

A partir da pergunta que dá título a este artigo, pretendemos posicionar o pensamento de Michel Foucault em relação ao materialismo através de uma análise que contemple as três fases de seu pensamento, a saber, a arqueologia, a genealogia e a ética. Mediante esta análise, concluímos não só pela filiação do pensamento de Michel Foucault no campo mais amplo e plural dos materialismos, mas também pela radicalidade que o filósofo assume em relação ao materialismo em todas as fases de seu (...) pensamento. Do ponto de vista da arqueologia, argumentamos que a tomada do discurso não em seu caráter representativo, significativo ou teleológico, mas na concretude e singularidade de seu aparecimento, reforça de forma significativa o materialismo; em relação à genealogia, mostramos como a microfísica do poder, ao voltar-se contra os efeitos de hegemonia que produzem a abstração dos Grandes Conceitos e das Grandes Coisas, revelam a materialidade de um jogo de forças sujeitado pelas formas oficiais do saber e do poder; por fim, do ponto de vista da ética, esclarecemos que o âmbito da análise da relação de si consigo não consiste no domínio da interioridade, refúgio último do imaterialismo, mas justamente no âmbito da produção de subjetividade determinada por uma relação com a exterioridade, a alteridade e o fora. Dessa forma, consideramos a noção de Materialismo Radical pertinente para compreendermos, de forma mais rigorosa, tanto certas características próprias ao pensamento de Michel Foucault, quanto sua indubitável filiação ao materialismo.

When we speak about different interpretations of quantum mechanics it is suggested that there is one single quantum theory that can be interpreted in different ways. However, after an explicit characterization of what it is to interpret quantum mechanics, the right diagnosis is that we have a case of predictively equivalent rival theories. I extract some lessons regarding the resulting underdetermination of theory choice. Issues about theoretical identity, theoretical and methodological pluralism, and the prospects for a realist stance towards quantum (...) theory can be properly addressed once we recognize that interpretations of quantum mechanics are rival theories.

This paper is concerned with the claim that supervaluationist consequence is not classical for a language including an operator for definiteness. Although there is some sense in which this claim is uncontroversial, there is a sense in which the claim must be qualified. In particular I defend Keefe's position according to which supervaluationism is classical except when the inference from phi to Dphi is involved. The paper provides a precise content to this claim showing that we might provide complete (and (...) sound) systems of deduction for supervaluationist consequence in which proofs are completely classical with the exception of a single last step (involving the above mentioned inference).

Rising economic inequality has aggravated long-standing labor market disparities, with one exception: government employment. This article considers the puzzle of black-white wage parity in the American public sector. African Americans are more likely to work in the public than in the private sector, and their wages are higher there. The article builds on prior work emphasizing institutional factors conditioning this outcome to argue that employee mobilization can motor it. As public sector unions gained political influence postwar, their large constituencies of (...) black, blue-collar workers, drawing on both militant and nonviolent tactics of the urbanizing civil rights movement, advocated for improved working conditions. Archival sources confirm this pattern at the federal level. The employment and activism of African Americans in low-skilled federal jobs pivoted union attention to blue-collar issues and directly contributed to the enactment of a transparent, universal wage schedule for the blue-collar federal workforce. The result was greater pay parity for African Americans, as well as for other disadvantaged groups. (shrink)

According to a popular narrative, in 1932 von Neumann introduced a theorem that intended to be a proof of the impossibility of hidden variables in quantum mechanics. However, the narrative goes, Bell later spotted a flaw that allegedly shows its irrelevance. Bell’s widely accepted criticism has been challenged by Bub and Dieks: they claim that the proof shows that viable hidden variables theories cannot be theories in Hilbert space. Bub’s and Dieks’ reassessment has been in turn challenged by Mermin and (...) Schack. Hereby I critically assess their reply, with the aim of bringing further clarification concerning the meaning, scope and relevance of von Neumann’s theorem. I show that despite Mermin and Schack’s response, Bub’s and Dieks’ reassessment is quite correct, and that this reading gets strongly reinforced when we carefully consider the connection between von Neumann’s proof and Gleason’s theorem.

It is a widespread belief that the Kochen-Specker theorem imposes a contextuality constraint on the ontology of beables in quantum hidden variables theories. On the other hand, after Bell’s influential critique, the importance of von Neumann’s wrongly called ‘impossibility proof’ has been severely questioned. However, Max Jammer, Jeffrey Bub and Dennis Dieks have proposed insightful reassessments of von Neumann’s theorem: what it really shows is that hidden variables theories cannot represent their beables by means of Hermitian operators in Hilbert space. (...) Hereby I show that i) the very same constraint can be derived from Gleason’s theorem, and that ii) if we consider the import of von Neumann’s and Gleason’s theorems, the relevance of the Kochen-Specker theorem for hidden variables theories gets substantially weakened: it does not force them to be contextual in any interesting sense of the term.

Nietzsche understands that the world unfolds as a will to power. If we want to properly understand this cosmological perspective, we must start by attributing immanent activity not only to organisms, but also to beings called “inorganic”. With this in mind, in this article we examine, in an “ascending” way, the features of the vital becoming in both strata, that is, from the minerals, with their attractions and repulsions, until reaching the man himself and his conscious operations. All the problems (...) involved in this monistic perspective are approached from argumentations that are based on Nietzsche’s readings. Strauss, Dubois Reymond, Herzen, Spencer, Lange, Delfœuf, are some of the cited sources that allow this writing to give an account of how Nietzsche makes life prevail, beyond being, as the primordial phenomenon in all orders.

In this paper I argue that the case of Einstein׳s special relativity vs. Hendrik Lorentz׳s ether theory can be decided in terms of empirical evidence, in spite of the predictive equivalence between the theories. In the historical and philosophical literature this case has been typically addressed focusing on non-empirical features. I claim that non-empirical features are not enough to provide a fully objective and uniquely determined choice in instances of empirical equivalence. However, I argue that if we consider arguments proposed (...) by Richard Boyd, and by Larry Laudan and Jarret Leplin, a choice based on non-entailed empirical evidence favoring Einstein׳s theory can be made. (shrink)

In 1991 Larry Laudan and Jarret Leplin proposed a solution for the problem of empirical equivalence and the empirical underdetermination that is often thought to result from it. In this paper we argue that, even though Laudan and Leplin’s reasoning is essentially correct, their solution should be accurately assessed in order to appreciate its nature and scope. Indeed, Laudan and Leplin’s analysis does not succeed in completely removing the problem or, as they put it, in refuting the thesis of underdetermination (...) as a consequence of empirical equivalence. Instead, what they show is merely that science possesses tools that may eventually lead out of an underdetermination impasse. We apply their argument to a real case of two empirically equivalent theories: Lorentz’s ether theory and Einstein’s special relativity. This example illustrates the validity of Laudan and Leplin’s reasoning, but also shows the importance of the reassessment we argue for. (shrink)

Substructural approaches to paradoxes have attracted much attention from the philosophical community in the last decade. In this paper we focus on two substructural logics, named ST and TS, along with two structural cousins, LP and K3. It is well known that LP and K3 are duals in the sense that an inference is valid in one logic just in case the contrapositive is valid in the other logic. As a consequence of this duality, theories based on either logic are (...) tightly connected since many of the arguments for and objections against one theory reappear in the other theory in dual form. The target of the paper is making explicit in exactly what way, if any, ST and TS are dual to one another. The connection will allow us to gain a more fine-grained understanding of these logics and of the theories based on them. In particular, we will obtain new insights on two questions concerning ST which are being intensively discussed in the current literature: whether ST preserves classical logic and whether it is LP in sheep’s clothing. Explaining in what way ST and TS are duals requires comparing these logics at a metainferential level. We provide to this end a uniform proof theory to decide on valid metainferences for each of the four logics. This proof procedure allows us to show in a very simple way how different properties of inferences (unsatisfiability, supersatisfiability and antivalidity) that behave in very different ways for each logic can be captured in terms of the validity of a metainference.
