No debate acerca da singularidade de, pelos menos, alguns de nossos pensamentos sobre o mundo, assume-se corriqueiramente que o responsável pela natureza singular do episódio mental não é o próprio episódio e, sim, a proposição singular expressa quer por um proferimento assertórico de sentença singular autônoma, quer pela cláusula complementar em um relato de atribuição de atitude proposicional. As rotas semânticas padrão assumem que a singularidade do episódio mental (conceitual) é por assim dizer “herdada” da singularidade do conteúdo. Argumento que (...) este pressuposto apresenta uma lacuna, pois desconsidera o papel desempenhado em certos atos de pensamento, chamados de episódicos, por habilidades cognitivas tais como a capacidade de perceber objetos particulares, de vivenciar (novamente) ou de projetar-se mentalmente em direção a acontecimentos particulares pessoais, diretamente responsáveis por sua singularidade. No entanto, contra a tese de que haveria capacidades episódicas aí envolvidas, argumento que a singularidade dos atos de pensar episódicos se dá pelo exercício pontual no espaço e no tempo dessas capacidades e há, portanto, um sentido não derivado em que eles podem ser qualificados como singulares.

Logical Investigations (notably, The Thought) is one of the works wherein Frege voices his hostility to psychologism in logic, science, and semantics. Such hostility lies, arguably, behind his threefold conceptual distinction between thought (Gedanke), thinking (Denken), and ideas (Vorstellungen). In this essay I investigate, to begin with, Frege’s motivations for drawing the distinction and keeping thinking episodes (one of the meanings of ‘thoughts’ in English) out of the picture. It turns out, or so I argue, that psychologism threatens, on Frege’s (...) view, to destroy the objectivity requirement by which thoughts are defined as answerable contents. I then draw a connection between this feature in Frege’s view and an on-going debate in philosophy of mind and language over the nature of world-directed thoughts and show that the feature lies at the heart of the singularist stance. Finally, I show that, despite Frege’s own hostility to all that bears the mark of the subjective in logic, science, and semantics, a psychological argument can be mounted in support of singularism (i.e. the view that some of our thoughts are about particulars qua particulars) using his disparaged notion of idea (Vorstellung) and that, appearances notwithstanding, the argument is compatible with the objectivity requirement on answerable thought-contents.

This paper considers one of the most significant and controversial attempts to account for the meaning of pejoratives as lexical items, namely Hom and May’s. After outlining the theory, we pinpoint sets of pejorative sentences that come out true on their account and for which the question as to whether they are compatible with the view advocated by them (so-called Moral and Semantic Innocence) remains open. Helping ourselves to the standard model-theoretical framework Hom and May (presumably) work in, we prove (...) they are compatible with the view. Given that the issues of both the moral import of pejoratives and the practical effects of their utterance are not settled by the proof, we then highlight unwelcome moral and pragmatic implications for some of the pejorative sentences under scrutiny, thereby showing that the view, broadly understood, is not as morally and semantically innocuous as it is meant to be.

In this essay I consider Kaplan’s challenge to Frege’s so-called dictum: “Logic (and perhaps even truth) is immune to epithetical color”. I show that if it is to challenge anything, it rather challenges the view (attributable to Frege) that logic is immune to pejorative colour. This granted, I show that Kaplan’s inference-based challenge can be set even assuming that the pejorative doesn’t make any non-trivial truth-conditional (descriptive) contribution. This goes against the general tendency to consider the truth-conditionally inert logically irrelevant. (...) But I take it that Kaplan is right and take his examples to show that truth-conditional inertness need not entail inferential inertness. I end up assessing the Kaplan-Frege “debate” as giving edge to the former to the extent that clarity is achieved through Kaplanian inferences on what should be considered part of the explanandum.

Quoique l'on ne trouve qu'un nombre limité de références à Nicod dans les manuscrits de la période dite « intermédiaire » de Wittgenstein, une lecture attentive de La Géométrie dans le monde sensible s'avère pourtant décisive pour comprendre la nature du projet phénoménologique de Wittgenstein de la fin des années vingt. Nous nous proposons de montrer que la prise en compte ainsi que la reformulation du problème posé par Nicod en 1924, celui de la nature de la relation d'inclusion spatiale, (...) conduit Wittgenstein à remplacer dès 1929 l'ancien critère logique du simple et du complexe (celui du Tractatus logico-philosophicus) par un critère phénoménologico-grammatical inédit et désabsolutisé applicable à toute donnée visuelle quelle qu'elle soit. Plus généralement, la priorité donnée par Wittgenstein au visuel dans son « investigation phénoménologique des impressions sensorielles » trouve sa meilleure justification dans l'esquisse par Nicod d'une géométrie de la vision à la fois complète et indépendante. Nous montrons en particulier que les propriétés structurales du champ visuel mises au jour par Nicod dans sa construction (diversité et simultanéité des places sensibles, coloréité) sont tacitement utilisées par Wittgenstein pour justifier la possibilité d'une description phénoménologique conçue, précisément, comme description des places ou « localités » constitutives de cet espace perceptif.

Starting from Brentano’s classical characterization of intentionality, we review the radical enactivist proposal about basic cognition and show that the underlying assumption that stripping teleosemantics of its representationalist commitments results in no explanatory loss is unwarranted. Significant features of basic cognition are lost, or so we argue, with the RECtification of teleosemantics that are retrieved by means of an alternative dubbed metaphysically non-committal content-ascriptivism.

In this critical notice we review Bozickovic's recent attempt to settle two interrelated issues: (i) the issue of the cognitive significance of indexical thoughts expressed at a time in the face of difficulties posed by cases in which the subject either mistakes two objects for one or one for two different objects; (ii) that of the cognitive dynamics of temporal indexical thoughts in the face of difficulties posed by cases in which the belief seems to be retained while the proper (...) adjustments fail to be made (that is, in cases such as Rip Van Winkle's). We argue that, despite its elegance and merits, the proposal falls short of accounting for the problematic cases in their full complexity. For one thing, the intended non-modal construal of Frege's Criterion of Difference promoted by Bozickovic does not block, in our view, the "proliferation" of senses brought about by the occasion-sensitivity of the individuation of demonstrative thoughts. For another, the proposal fails to appreciate the need for the subject to have an adequate conception of the object of her thought when it comes to orienting herself in space and time. That being so, we conclude that neither (i) nor (ii) is settled. (shrink)

In this article, I show and discuss the relevance of Wittgenstein's arguments as to the spatial structure of sight to recent issues in the philosophy of mind. The first, bearing upon the dimensionality of the manifolds at play in depiction, plays a critical role in Clark's attempt to provide an independent account ofqualiaand of their differentiative properties. The second, pertaining to the properly spatial structure formed by the data of sight, is explicitly appealed to in the debate on the realistic (...) character of any genuinely spatial scheme. I argue that if Wittgenstein rightly assumes that the simultaneous presence of sensible places in vision is a key condition for objectivity, he fails nevertheless to warrant the allegedly realistic character of the scheme employed in his own search for a phenomenological description of the visual field.

I discuss the view tentatively put forward by Recanati in Mental Files to turn two potentially contradictory claims compatible: the claim to the effect that acquaintance is a necessary condition of singular thought and the claim that we do entertain acquaintanceless singular thoughts (i.e. thoughts directed at particulars as particulars). Key to the proposal is a normative construal of the acquaintance constraint. I show the proposal as it stands is wanting, first, because the norm the users of descriptive names are (...) subject to has no (determinate) conditions of satisfaction within the framework ; second, because the kind of mental simulation involved in exploiting the norm in this type of case is misdescribed as a “local lapse into fiction” ; third, because it leaves the issue pertaining to the conditions of satisfaction of the acquaintance norm over time unaddressed.

I take issue with Glezakos’s explanation of why Frege’s puzzle is un-puzzling. On her view, Frege’s statement – how can sentences of the form a=a and a=b, if true, differ in cognitive value if they express the same semantic content/are made true by the same object’s self-identity? – should not be considered any puzzling either because it is on the whole circular, or because, neutrally stated, it cannot even be set up. I argue against this that if, as she takes (...) it, Frege’s statement is “problematic” it is not for the reasons she gives, but because it rests upon a couple of questionable assumptions: i) there is no ambiguity as to which aspect of the sign (in its relation to the referent) is relevant to a neutral statement of the puzzle ii) it is of the (sentence) forms themselves one may sensibly say they differ in cognitive value.

In this paper, I discuss a view of de re thoughts that can be naturally endorsed in the wake of Russell's account. This is the view that a thought is about the very thing (res) rather than a mere characterization of it if and only if it is constitutively tied, if not to the existence, at least to the identity of its object and the thinker knows which/who the object of his/her thought is. Faced with the challenge of accommodating far (...) from uncommon cases of mistaken identity or substantial confusion on the part of the subject, I argue that the integrity of the view can be preserved and that the restrictions set on its truth by the advocates of the two-component picture and the anti-essentialists can be lifted.

No presente verbete faço a revisão crítica de algumas entre as mais expressivas tentativas de resolver o chamado ‘problema da dinâmica cognitiva’. De acordo com Kaplan (1989) – que é responsável pelo próprio apelido, a questão que se coloca é: o que significa dizer de uma pessoa que expressou uma crença particular num determinado contexto de proferimento que ela reteve ou mudou de crença fora desse contexto? E caso ajustes (linguísticos, psicológicos) sejam necessários para manter a relação com o conteúdo (...) semântico original, quais são nossas intuições a respeito de casos em que um sujeito cognitivamente saudável perdeu temporariamente a noção do tempo e/ou a capacidade de rastrear objetos no espaço? Exploro diversas respostas a essas perguntas com o intuito de dizer se elas conseguem acomodar os fatos (semânticos, epistêmicos, cognitivos) aí envolvidos. Abstract: In this paper I review some of the most significant attempts to solve the so-called ‘problem of cognitive dynamics’. According to Kaplan (1989), who coined the phrase, the following questions arise – as to the topic: what does it means to say of an individual who expressed a particular belief in a given context of utterance that he/she has re tained orchanged his/her mind with respect to it once the context is left? And assuming that (linguistic or psychological) adjustments are required to keep on being related to the original semantic content, what are our intuitions about the case of a cognitively healthy subject who temporarily lost the ability to keep track of time and/or objects in space? I investigate different ways of answg those questions with a view to saying whether they accommodate all the relevant (semantic, epistemic, cognitive) facts or not. (shrink)

RESUMO O presente artigo contempla uma das tentativas mais significativas e controversas de explicar o significado de pejorativos como itens lexicais, a saber, a de Hom e May. Após apresentarmos em linhas gerais a teoria, identificamos conjuntos de sentenças pejorativas que saem verdadeiras nessa teoria e para as quais a questão da sua compatibilidade com a visão por eles defendida (a chamada Inocência Moral e Semântica) permanece em aberto. Explorando o arcabouço teórico padrão da teoria dos modelos em que Hom (...) e May (presumivelmente) trabalham, damos uma prova de sua compatibilidade com a visão. Dado que as questões relativas tanto à importância moral de pejorativos quanto aos efeitos práticos de seu proferimento não são resolvidas pela prova, destacamos, em seguida, implicações morais e pragmáticas indesejáveis para algumas das sentenças pejorativas sob escrutínio, mostrando assim que a visão de Hom e May, interpretada de maneira ampla, não é tão moral e semanticamente inócua como deveria ser.

Modelling the semantic behaviour of expressives in such a way that one be in a position to predict some, at least, of their distinctive properties is the purpose of any theory aiming at accounting for so-called expressive meaning. In this paper, we review a semantic framework coined by its author the Theory of Bias. We show that the two-tiered account of the meaning of expressives (notably, sentential interjections and pejorative epithets) favored by this framework has the resources to provide a (...) consistent explanation of their semantic behaviour in prima facie awkward statements such as ‘alas, I am unfavorably disposed towards something’ or ‘that stupid Trump isn’t stupid’. On the critical side, we argue that, not being intended to account for the meaning of expressives alone, the theory has hard times explaining the unshiftability of their bias, as opposed to the shiftability of the bias of discourse particles —a further member, according to some authors, of the category of expressives lato sensu— and that it fails to pinpoint unpluggability as the crucial test for expressive content. We conclude that, in spite of its merits, the theory need be theoretically enhanced and methodologically sharpened. (shrink)

One of the conundrums of Wittgenstein’s so-called ‘1914–1916 Notebooks’ concerns the role played by the visual instances of logical analysis. As a matter of fact, in discussing in that work the requirement that the logical analysis of meaningful sentences be complete, Wittgenstein often takes as examples statements about the colored parts of the subject's visual image (Gesichtsbild). In view of this, it might be thought that the requirement is not laid down in the Notebooks on logical grounds, but somehow on (...) psychological or psychophysical ones. In this paper I argue this is not so and that the requirement is exemplified rather than justified by the analysis of statements about the products of the subject’s visual imagination. I also argue that, on Wittgenstein’s syntactic notion of a complete logical analysis, our unanalyzed statements embody as they are the requirement that their sense be fully determinate; which is just what is meant by the idea that the analysis must be complete.

Parmi toutes les pensées que nous avons sur le monde, certaines portent sur des objets particuliers de façon plus directe (ou moins lâche) que les pensées dites descriptives et sont, pour cette raison, qualifiées de singulières. La pensée exprimée par l’énoncé : « Jean Nicod est mort en 1924 » n’est, intuitivement, pas la même que celle exprimée par l’énoncé : « L’auteur de la Géométrie dans le monde sensible est mort en 1924 », ne serait-ce que parce que la (...) seconde ne porte sur l’individu particulier auquel réfère le nom propre Jean Nicod (dans le premier énoncé) qu’indirectement, via la satisfaction par ce dernier d’un ensemble de conditions descriptives. La thèse selon laquelle notre espace cognitif serait peuplé d’authentiques pensées singulières n’est pourtant pas, loin s’en faut, triviale et mérite d’être évaluée à la lumière des différentes approches possibles du phénomène. Ce livre tente de le cerner en présentant et évaluant les théories sémantiques, épistémiques et cognitives les plus significatives de la pensée singulière. Il promeut une approche intégrée qui vise à donner son juste poids aux aspects mis en lumière par ces théories. Il est assorti d’un commentaire de deux extraits de texte: l’un, de Bertrand Russell, souvent considéré comme le locus classicus de la thèse singulariste et des théories épistémiques de l’accointance; l’autre, du philosophe américain contemporain Kent Bach, sur la portée de la conception essentialiste orthodoxe des pensées de re.

Neste artigo, tentamos mostrar que um problema comum aos capítulos XVI e XX das Observações filosóficas é o da aplicabilidade dos conceitos e «proposições» da geometria à realidade física e perceptiva (visual, em particular), e que o modo pelo qual Wittgenstein aborda esse problema nessa obra difere radicalmente, a despeito de aparentes similitudes, daquele que caracteriza as teorias semânticas do a priori visual em termos de estipulações (notadamente, o de Carnap em 1922). O esclarecimento do estatuto dos enunciados sobre os (...) objetos do espaço visual como regras de sintaxe e a abordagem do problema da aplicação de nossos conceitos geométricos à realidade perceptiva em termos de condições práticas de emprego permite a Wittgenstein dissolver, não sem alguma ambiguidade no vocabulário empregado, as falsas aparências ontológicas suscitadas pelas teorias que postulam a existência de um universo de discurso intermediário entre os corpos físicos e os números.

Wittgenstein a abondamment critique l'idee qu'il serait necessaire d'admettre l'existence d'un medium spatial alternatif ( l'espace visuel) pour rendre compte des differentes applications possibles de nos concepts geometriques et spatiaux. Notre objectif ici est de montrer la pertinence de cette critique. Pour ce faire, nous proposons une relecture des remarques qu'il consacre aux exemples visuels d'analyse dans les Carnets, aux aspects spatiaux de la theorie de l'image dans le Tractatus, a son propre projet phenomenologique de description de l'experience visuelle en (...) 1929, ainsi qu'a la maniere, philosophiquement fallacieuse, de poser le probleme de l'application en termes d'interpretations semantiques.

"À une époque où la cinéphilie n'est plus qu'une paraphilie parmi les autres, aussi estimable et inoffensive qu'une autre, en un temps où la sédition installée tient lieu d'horizon, il y a sans doute quelque naïveté à prétendre se démarquer de la modernité en se réclamant d'une "cinéphilie dissidente". Pourtant sous l'insurrection permanente, des règles intangibles et des principes incontestables demeurent, qu'il est nécessaire d'enfreindre. Derrière l'équivalence des opinions et la relativité des goûts, de nouvelles hiérarchies se sont bâties, qu'il (...) importe de renverser. Cette attitude d'opposition serait à son tour éminemment moderne s'il ne s'agissait par ce refus, de promouvoir une autre attention aux faits, une autre rapport à autrui, que ceux que notre époque favorise. Lorsque nous aurons admis que le cinéma moderne nous a dépossédés de nos mots, en y substituant les siens, qui décrivent de mille feux ce qui s'éteint, lorsque nous aurons saisi que nous ne parlons qu'en son non, ne répétons que ses désordres, ne prions que ses décalogues rafraîchis, nous aurons alors tout le temps de regretter notre silence. Dans ces conditions, c'est bien par l'écriture qu'il s'agit d'instaurer une relation cette fois intempestive avec l'image cinématographique. À travers le prisme de plus de deux cents films, mêlant la critique cinématographique et le journal intime, l'analyse et l'aphorisme, cet essai se propose de résister à la cinéphilie officielle, absolument indolore, qui n'est plus qu'une technique parmi d'autres d'embrigadement. Sous la forme d'abécédaire, de A comme Artifices à Z comme Zombies, en passant par l'Enfance, la Honte, le Messie, les Nazis ou la Pornocratie, il n'est autre qu'une tentat. (shrink)

The key to this study lies in my own identity as a researcher who specializes in the fifteenth century and Franciscan reforms, especially the confrontation in eastern Central Europe between the theory of the via media based on a return to the Martianian Constitutions, and the Observance sub vicariis brought by Giovanni of Capistrano when he crossed the Alps in 1451.2 The major aspect of this is a view on the “pre-history” of the Libellus ad Leonem, which was written in (...) 1513 by Paolo Giustiniani and Pietro Quirini in preparation of the Fifth Lateran Council. This “pre-history” concerns a century of transformations of the links between the Observant reforms, humanist culture and the.. (shrink)

The horse was essential to past human societies but became a recreational animal during the twentieth century as the world became increasingly mechanized. As the author reviews here, recent studies of ancient genomes have revisited the understanding of horse domestication, from the very early stages to the most modern developments. They have uncovered several extinct lineages roaming the far ends of Eurasia some 4000 years ago. They have shown that the domestic horse has been significantly reshaped during the last millennium (...) and experienced a sharp decline in genetic diversity within the last two centuries. At a time when no truly wild horses exist any longer, this calls for enhanced conservation in all endangered populations. These include the Przewalski's horse native to Mongolia, and the many local breeds side‐lined by the modern agenda, but yet representing the living heritage of over five millennia of horse breeding.

Ramsey’s theorem asserts that every k-coloring of $[\omega ]^n$ admits an infinite monochromatic set. Whenever $n \geq 3$, there exists a computable k-coloring of $[\omega ]^n$ whose solutions compute the halting set. On the other hand, for every computable k-coloring of $[\omega ]^2$ and every noncomputable set C, there is an infinite monochromatic set H such that $C \not \leq _T H$. The latter property is known as cone avoidance.In this article, we design a natural class of Ramsey-like theorems encompassing (...) many statements studied in reverse mathematics. We prove that this class admits a maximal statement satisfying cone avoidance and use it as a criterion to re-obtain many existing proofs of cone avoidance. This maximal statement asserts the existence, for every k-coloring of $[\omega ]^n$, of an infinite subdomain $H \subseteq \omega $ over which the coloring depends only on the sparsity of its elements. This confirms the intuition that Ramsey-like theorems compute Turing degrees only through the sparsity of its solutions. (shrink)

By combining state‐of‐the‐art approaches in ancient genomics, Meyer and co‐workers have reconstructed the mitochondrial sequence of an archaic hominin that lived at Sierra de Atapuerca, Spain about 400,000 years ago. This achievement follows recent advances in molecular anthropology that delivered the genome sequence of younger archaic hominins, such as Neanderthals and Denisovans. Molecular phylogenetic reconstructions placed the Atapuercan as a sister group to Denisovans, although its morphology suggested closer affinities with Neanderthals. In addition to possibly challenging our interpretation of the (...) fossil record, this study confirms that genomic information can be recovered from extremely damaged DNA molecules, even in the presence of significant levels of human contamination. Together with the recent characterization of a 700,000‐year‐old horse genome, this study opens the Middle Pleistocene to genomics, thereby extending the scope of ancient DNA to the last million years.

In everyday situations, and particularly in some sport and working contexts, humans face an inherently unpredictable and uncertain environment. All sorts of unpredictable and unexpected things happen but typically people are able to skillfully adapt. In this paper, we address two key questions in cognitive science. First, how is an agent able to bring its previously learned skill to bear on a novel situation? Second, how can an agent be both sensitive to the particularity of a given situation, while remaining (...) flexibly poised for many other possibilities for action? We will argue that both the sensitivity to novel situations and the sensitivity to a multiplicity of action possibilities are enabled by the property of skilled agency that we will call metastable attunement. We characterize a skilled agent’s flexible interactions with a dynamically changing environment in terms of metastable dynamics in agent-environment systems. What we find in metastability is the realization of two competing tendencies: the tendency of the agent to express their intrinsic dynamics and the tendency to search for new possibilities. Metastably attuned agents are ready to engage with a multiplicity of affordances, allowing for a balance between stability and flexibility. On the one hand, agents are able to exploit affordances they are attuned to, while at the same time being ready to flexibly explore for other affordances. Metastable attunement allows agents to smoothly transition between these possible configurations so as to adapt their behaviour to what the particular situation requires. We go on to describe the role metastability plays in learning of new skills, and in skilful behaviour more generally. Finally, drawing upon work in art, architecture and sports science, we develop a number of perspectives on how to investigate metastable attunement in real life situations. (shrink)

The question of the Hegelian heritage within the Marxian dialectic is a classic one that is still an open one, after more than a century of fruitful and various inquiry. In order to tackle the issue from a new perspective, we must first distinguish between, on the one hand, the subjective dialectic, or logic of Marxian thought, which is clearly inherited from Hegel, and, on the other hand, the objective dialectic, or logic of reality itself, which Marx arrived at by (...) way of a frontal opposition to his master, even as he took up the latter’s “rational kernel” in order to invert it, substituting for Hegel’s idealist philosophy of creation a materialist conception of production and replacing the logic of negativity by a logic of produ-activity. Thus conceptualized by Marx, the gnoseological dialectic and dialectical materialism interact rationally. This enables us to renew the foundations of a dialectical materialism. Unrelated to stalinist « diamat », such a conception is well equipped to demonstrate its effectiveness for the knowledge and understanding of realities, both in terms of their irreducible material singularity, apprehended according to their constitutive historicity, and as elements of a certain real totality which is in process.
