This paper examines from a historical perspective Tarski's 1936 essay, "On the concept of logical consequence." I focus on two main aims. The primary aim is to show how Tarski's definition of logical consequence satisfies two desiderata he himself sets forth for it: (1) it must declare logically correct certain formalizations of the -rule and (2) it must allow for variation of the individual domain in the test for logical consequence. My arguments provide a refutation of some interpreters of Tarski, (...) and notably John Etchemendy, who have claimed that his definition does not satisfy those desiderata. A secondary aim of the paper is to offer some basic elements for an understanding of Tarski's definition in the historical logico-philosophical context in which it was proposed. Such historical understanding provides useful insights on Tarski's informal ideas on logical consequence and their internal cohesion. (shrink)

I offer a new objectivist theory of the contents of color language and color experience, intended especially as an account of what normal intersubjective variation in color perception and classification shows about those contents. First I explain an abstract account of the contents of color and other gradable adjectives; on the account, these contents are certain objective properties constituted in part by contextually intended standards of application, which are in turn values in the dimensions of variation associated with the adjectives. (...) Then I propose an explanation of normal variations in linguistic color classification; these are postulated to be effects of differences in intended standards for the color adjectives appearing in the classifying predicates. Next, I consider a potential objection to this explanation, based on the suggestion that contextual content should be more accessible than the explanation predicts. In reply, I point out that contextual content is occasionally opaque to unsophisticated reflection. Finally, I present a companion account of the contents of color experiences on which these represent an object as lying on certain salient intervals in the chromatic dimensions, and I show how the account accommodates intersubjective variation in color perception.

The main aim of this paper is to point out that Davidsonian and Fregean theories of quotation do not accommodate certain facts about disquotation. A second aim is to dispel some errors of interpretation in a common Davidsonian reading of Tarski's claims about quotation. This allows a correct exegesis of Tarski's view, which is then seen not to be affected by the arguments usually adduced against the view wrongly attributed to Tarski. Finally, a Tarskian view is proposed of some problems (...) about quotation not addressed by Tarski. (shrink)

This paper examines the question of the extensional correctness of Tarskian definitions of logical truth and logical consequence. I identify a few different informal properties which are necessary for a sentence to be an informal logical truth and look at whether they are necessary properties of Tarskian logical truths. I examine arguments by John Etchemendy and Vann McGee to the effect that some of those properties are not necessary properties of some Tarskian logical truths, and find them unconvincing. I stress (...) the point that since the hypothesis that Tarski's definitions are extensionally correct is deeply entrenched, the burden of proof is still on the shoulders of Tarski's critics, who have not lifted the burden.

Timothy Williamson’s potentially most important contribution to epistemicism about vagueness lies in his arguments for the basic epistemicist claim that the alleged cut-off points of vague predicates are not knowable. His arguments for this are based on so-called ‘margin for error principles’. This paper argues that these principles fail to provide a good argument for the basic claim. Williamson has offered at least two kinds of margin for error principles applicable to vague predicates. A certain fallacy of equivocation seems to (...) underlie his justification for both kinds of principles. Besides, the margin for error principles of the first kind can be used in the derivation of unacceptable consequences, while the margin for error principles of the second kind can be shown to be compatible with the falsity of epistemicism, under a number of assumptions acceptable to the epistemicist.

Abstract: I address the issue of how pretence emerged in evolution by reviewing the (mostly negative) evidence about pretend behaviour in non-human primates, and proposing a model of the type of information processing abilities that humans had to evolve in order to be able to pretend. Non-human primates do not typically pretend: there are just a few examples of potential pretend actions mostly produced by apes. The best, but still rare, examples are produced by so-called 'enculturated' apes (reared by humans) (...) and among them specially those that have been systematically trained to use symbols (so-called 'linguistic' apes). A hypothesis that would explain the lack of pretence in apes is that they lack the mentalistic ability of theory of mind. However, in the last years apes have been demonstrated to possess relatively sophisticated social cognitive skills, some of them ontogenetically appearing in humans alongside with or even after pretend play. As a solution to the paradox, I discuss a model according to which pretence is supported by a mechanism capable of computing intentional relations with non-existing objects or properties (Intentional non-existence), as opposed to mechanisms computing intentional relations with existing, although not necessarily currently perceived, objects (Intentional availability). Apes possess the latter, which allows them to solve a variety of theory of mind tasks, but not the former, which typically prevents them from developing pretence. (shrink)

Respect for human embryos is often defended on the basis of the potentiality argument: embryos deserve respect because they already possess potentially the features that in adults are fully actualized. Opponents of this argument challenge it by claiming that if embryos should be respected because they are potentially adults, then gametes should be respected because they are potentially embryos. This article rejects this reductio ad absurdum argument by showing that there are two different types of potentiality involved so that the (...) transitivity of potentiality does not hold up in this case. Respect for embryos does not logically entail respect for gametes. (shrink)

This paper presents some difficulties for Timothy Williamson's epistemicist view of vagueness and for an argument he gives in its defense. First, I claim that the argument, which uses the notion of an "omniscient speaker", is question-begging. Next, I argue that some presumably true scientific hypotheses, which postulate certain relations between everyday vague predicates and scientific predicates, make the central theses of epistemicism highly implausible. Finally, I show that the "margin for error principles" used by Williamson to explain away the (...) kind of ignorance conjectured by epistemicism lead to new sorites-like arguments with unacceptable conclusions.

“Matrixes and Frames: Two Figures of Norm Functioning in the Work of Judith Butler”. The concepts of “intelligibility matrix” and “frame”, each corresponding to different periods in the thought of the feminist philosopher Judith Butler, seem to converge in so many aspects that one is tempted to hold that they may be used indistinctly. Nevertheless, the problem this paper deals with is the possible uniqueness the usage of the latter concept involves, thus pointing to the differences between both concepts. I (...) aim to solve the problem by studying the main sources that Butler herself uses in order to formulate the concept of frame, and by putting in evidence that which is gained by the use of that notion. I also aim to show more clearly the difference between the two concepts by appealing to their functions in the critique of speciffical cultural phenomenon: pornography as a frame and element of the heterosexual matrix.

Resumen Este artículo ofrece una lectura de la pintura renacentista según los principios establecidos por Leon Battista Alberti, uno de los primeros teóricos de la perspectiva en cuyo Tratado de pintura se refiere al cuadro como “una ventana abierta a la historia”. El concepto de historia empleado por Alberti, que se presta a numerosas interpretaciones, es abordado a partir de las reflexiones de Erwin Panofsky en torno a la perspectiva como “forma simbólica”, avanzando hacia una hipótesis en torno al carácter (...) simbólico de la configuración y representación del tiempo en el cuadro-ventana albertiano.This paper offers a reading of the renaissance painting according to the principles established by Leon Battista Alberti, one of the first theorists of perspective in painting which Trattato della pittura define the frame of the painting as “an open window into history”. The concept of history employed by Alberti, which lends itself to many interpretations, is approached from the reflections of Erwin Panofsky about the prospect as “symbolic form”, moving towards a hypothesis about the symbolic nature of the configuration and representation of time in the alberti’s window.

I defend a semantic theory of quotation marks, according to which these are ambiguous, as they have several different acceptations involving corresponding different conventional indications. In particular, in allusion (“mixed”) uses, the corresponding conventional indication is one with an adverbial or prepositional content, roughly equivalent to “using the quoted expression or an appropriate version of it”. And in “scare” uses, the corresponding conventional indication is that the enclosed expression should be used not plainly but in some broadly speaking distanced way, (...) or that it is being so used by the utterer. I also defend this view against some alternative views on which allusion and distance indications are to be seen as pragmatically conveyed. In particular, I consider several views that attempt to explain especially allusion and distance indications as pragmatic suggestions generated from a meager conventional basis, and I argue that they cannot accommodate a number of linguistic phenomena and reflectively supported theses about the use of quotation marks. I lay special emphasis on the fact that the main pragmatic theories fail to pass an extremely plausible test for challenges to polysemic accounts of an expression. (shrink)

Logic is formal in the sense that all arguments of the same form as logically valid arguments are also logically valid and hence truth-preserving. However, it is not known whether all arguments that are valid in the usual model-theoretic sense are truthpreserving. Tarski claimed that it could be proved that all arguments that are valid (in the sense of validity he contemplated in his 1936 paper on logical consequence) are truthpreserving. But he did not offer the proof. The question arises (...) whether the usual modeltheoretic sense of validity and Tarski's 1936 sense are the same. I argue in this paper that they probably are not, and that the proof Tarski had in mind, although unusable to prove that model-theoretically valid arguments are truth-preserving, can be used to prove that arguments valid in Tarski's 1936 sense are truth-preserving.

In order to understand the nature of human embryos I first distinguish between active and passive potentiality, and then argue that the former is found in human gametes and embryos (even in embryos in vitro that may fail to be implanted) because they all have an indwelling power or capacity to initiate certain changes. Implantation provides necessary conditions for the actualization of that prior, active potentiality. This does not imply that embryos are potential persons that do not deserve the same (...) respect as actual persons. To claim that embryos become persons is to understand the predicate person as a phase sortal, roughly equivalent to adult person. This entails that we would not be essentially persons. In order to explain the traditional understanding of person as a proper sortal rather than a phase sortal, the author distinguishes between proximate and remote potentiality, and shows that, unlike feline embryos, human embryos, by their genetic constitution, possess the remote potentiality to later exercise the typically human activities. It follows that they are already persons essentially. (shrink)

Contrary to what often seems to be the implicit belief, Tarski's 1933 version of the theorem on the indefinability of truth did not mention semantic notions, either defined or intuitive. I state this version in a somewhat modernized form and explain briefly the self-imposed mathematico-philosophical constraints that led Tarski to formulate it as he did. I also point out that close attention to its content suggests a refined view of the exact contrast between Tarski's achievement and Gödel's achievement in his (...) earlier discovery of another version of the result.

Brains enjoy a bodily life. Therefore animals are subjects with a point of view. Yet, coding betrays an anthropomorphic bias: we can, therefore they must. Here I propose a reformulation of Brette's question that emphasizes organismic perception, cautioning for misinterpretations based on external ideal-observer accounts. Theoretical ethology allows computational neuroscience to understand brains from the perspective of their owners.

Paulo Freire consistently upheld humanization and mutuality as educational ideals. This article argues that conceptualizations of knowledge and how knowledge is sought and produced play a role in fostering humanization and mutuality in educational contexts. Drawing on Mary Shelley’s novel Frankenstein, this article focuses on the two central characters who ‘ardently’ pursue knowledge at all costs. It will be argued that the text suggests two possible outcomes from the pursuit of knowledge. One is mutuality; the other is social disconnectedness.

Dentro de la obra madura de Spinoza, la _Ética_ y el _Tratado Teológico-Político _ se han analizado ampliamente. Sin embargo, el _Tratado Político_ ha sido menormente estudiado por ser una obra inconclusa y con problemas estructurales. Nosotros afirmamos que la teoría política más acabada de Spinoza se encuentra en el TP. En esta obra se sacan todas las consecuencias de guiarse por una noción estrictamente inmanente de la política. En ese sentido, el TP sigue de manera más coherente el programa (...) trazado por la doctrina fundamental de Spinoza expuesta en la _Ética_, y no el TTP. Esto nos lleva a la consideración de la política como tendencia en dos direcciones opuestas: ampliación de poder y concentración de poder. (shrink)

Taking as premises some reasonable principles about the essences of natural numbers, pluralities and sets, the paper offers two types of argument for the conclusions that the natural numbers could not be the Zermelo numbers, the von Neumann numbers, the “Kripke numbers”, or the positions in the ω-structure, among other things. These conclusions are thus Benacerrafian in form, but it is emphasized that the two kinds of argument offered in the paper are anti-Benacerrafian in substance, as they are perfectly compatible (...) and in fact congenial with some views on which the numbers could be things of certain other kinds.

The pretheoretical notions of logical consequence and of a logical expression are linked in vague and complex ways to modal and pragmatic intuitions. I offer an introduction to the difficulties that these intuitions create when one attempts to give precise characterizations of those notions. Special attention is given to Tarski’s theories of logical consequence and logical constancy. I note that the Tarskian theory of logical consequence has fared better in the face of the difficulties than the Tarskian theory of logical (...) constancy. Other theories of these notions are explained and criticized. (shrink)

Roy Sorensen has argued that a certain technical use of quotation marks to name the empty string supports a revised version of Davidson’s theory of quotation. I point out that Sorensen’s considerations provide no support for Davidson’s original theory, and I show that at best they support the revised Davidsonian theory only to the same extent that they support a simpler revised version of a Tarskian theory.

This paper reports a longitudinal study on the ontogeny of triadic cooperative interactions in a hand-reared lowland gorilla from 6 months to 36 months of age. Using the behavioural categories developed by Hubley and Trevarthen to characterize the origins of “secondary intersubjectivity” in human babies between 8–12 months of age, I chart the emergence of comparable coordinations of gestures and actions with objects and acts of dyadic communication. The findings show that the categories and concepts of secondary intersubjectivity are applicable (...) to the gorilla, who engages with people in cooperative actions with objects. The ontogeny of triadic interaction in the gorilla was very similar to that described in human infants, but more extended in time and with some peculiarities, such as the absence of pointing and showing gestures, some of whose functions might be taken over by contact gestures which in human infants may appear later in development. The results do not support claims of human uniqueness in the development of cooperative action, but suggest a heterochrony in some aspects of the ontogeny of triadic interactions leading to a divergence between gorilla and human infants within secondary intersubjectivity. Keywords: Triadic communication; secondary intersubjectivity; shared intentionality; cooperation; gorilla. (shrink)

Este artículo tiene como objetivo esclarecer la relación entre juicio y deseo en el pensamiento de Gilles Deleuze y destacar la importancia de Spinoza para la resolución de este problema. La concepción negativa del deseo es la base de la cultura y el pensamiento de Occidente; sin embargo, Spinoza nos propone una concepción afirmativa e inmanente. Estos elementos son fundamentales para esclarecer el sentido teórico y práctico de la propuesta de Gilles Deleuze en su obra, donde una concepción afirmativa del (...) deseo le permite proponer la existencia de dos imágenes del pensamiento: una imagen moral, la cual crítica; y, una imagen ética, que restituye, a partir de la teoría de los afectos y la naturaleza de Spinoza, el valor afirmativo del cuerpo y los afectos. Deleuze y Spinoza, así, nos proponen una imagen del pensamiento que sostiene el valor de lo afirmativo sobre lo negativo, es decir, que relieva la producción de lo diferente y lo múltiple sobre la jerarquía de lo idéntico o lo hegemónico.

Despite the triumphant rhetoric of mechanistic materialism, current biology has no shortage of unsolved fundamental problems. In 1981, seeking a way forward, Rupert Sheldrake proposed the hypothesis of “formative causation” as a unifying organizing principle of life. Expanding the concept of morphogenetic fields, Sheldrake posited a spatio‐temporal connection termed “morphic resonance” whereby the more often a self‐organizing process takes place, the easier it will be for it to take place in the future. After initial acclaim, his project was quickly met (...) with dogmatic skepticism, dismissed as scientific heresy, and ultimately ignored. Forty years later, the experimental implications of his ideas remain largely untested. Visionary or not, Sheldrake's case illustrates the conceptual resistance of the scientific enterprise to revise its own deepest theoretical commitments. Beyond career‐building selection pressures, young researchers need to be presented with the major questions in their field and encouraged to entertain radically alternative points of view. Science is what scientists make of it. (shrink)

The question whether the notion of rigidity can be extended in a fruitful way beyond singular terms has received a standard answer in the literature, according to which non‐singular terms designate kinds, properties or other abstract singular objects, and generalized rigidity is the same thing as singular term rigidity, but for terms designating such objects. I offer some new criticisms of this view and go on to defend an alternative view, on which non‐singular terms designate extensions in general, and generalized (...) rigidity is identity of extension across possible worlds. I develop some fundamental positive considerations that make this view virtually inevitable as a view of generalized rigidity, emphasizing its exclusive ability to offer a purely logical justification of the necessity of several kinds of statements that go beyond true identity statements between rigid singular terms.

He maintained that there are two main categories of truth: those that are a result of natural laws and those that are completely necessary since their opposite suggests contradiction. God can dispense solely with the latter rules, such as the law of human mortality. Although a doctrine of faith may conflict with second-type realities, it can never contradict first-type truths. Therefore, reason may not be able to completely understand an article of religion, even though it cannot be self-contradictory. Simply put, (...) mysteries like the Trinity are "above reason." However, how can we balance the odds in favor of a religious belief with those based on natural law and common experience? The presence and character of God, as well as the global harmony that underpins the providential creation and order of the universe, must all be considered when we make these choices. On the other hand, moving from the higher to the lower classes is also feasible. Since goodness has an immediate order to the higher pattern of the universal source of being, rational creatures are able to understand "the meaning of the good as such" (II-IIae q.2, a.3). The last good that theologians and philosophers examine is different; the former is the bonum ultimum, which can only be understood with the help of revelation, while the later is the beatific vision, which reason can understand. Both conceptions of the ultimate good have significant implications since they serve as the foundation for the political division between secular and ecclesiastical authority as well as the moral division between natural and supernatural virtues.

El proyecto de Neurath incluyó centralmente la tesis de la ciencia unificada por su funcionalidad para la acción política en aras de una humanidad mejor. Esto era así, porque la ciencia unificada era el instrumento fundamental para adoptar una unidad de acción, y ésta, a su vez, requería de una comunicación fluida la cual dependía de una cierta unidad del lenguaje de la ciencia. El resultado fue el convencionalismo radical anti-fundacional de Neurath de acuerdo al cual los científicos deben tomar (...) decisiones para adoptar objetivos, instrumentos para alcanzarlos e, incluso, para aceptar/rechazar hipótesis y enciclopedias. Dichas decisiones involucran necesariamente la presencia de “motivos auxiliares” como utilidad, la felicidad humana, mejorar la situación del proletariado, entre otros. En consecuencia, hay una fuerte interrelación entre ciencia y política, porque la primera es un instrumento fundamental para alcanzar exitosamente metas políticas y, principalmente, porque los motivos políticos pueden jugar un rol crucial en las decisiones de aceptación científica.

Student-centered pedagogy has been embraced by many feminist practitioners and educational theorists as an antidote to more “traditional” or “masculinist” forms of classroom relations, epistemological constructs, and theories of self. I will show that the margin-center schema, student-centered pedagogy’s foundational metaphor, undermines feminist projects when applied to teacher-student relations. Although the margin-center schema has been a useful diagnostic tool in feminist theory, it operates prescriptively in student-centered pedagogy. Student-centered pedagogy designates teachers’ “proper place” at the margins of classroom life, a (...) place that echoes bygone visions of domestic femininity. This paper is simultaneously a critique of student-centered pedagogy and a recuperative project to dislodge the work of John Dewey from the teacher-centered/student-centered binary. (shrink)

En este texto se estudia la lectura que Heidegger lleva a cabo en torno a la obra de Hölderlin tomando como eje la noción de “aporía”. Por ésta se comprende la imposibilidad de una respuesta o resolución con respecto a la cuestión del ser.

De este (...) modo, se comprueba cómo Hölderlin aporta el aparato léxico y conceptual que Heidegger desplegará en los años siguientes en su camino del pensar. (shrink)

La teoría del «mal radical en la naturaleza humana», expuesta por Kant en La religión dentro de los límites de la mera razón, hace contraste con el optimismo antropológico que empapa el Criticismo. Constituyó, sin duda, una importante denuncia frente a la banalidad de muchos optimismos ilustrados. Pero su letra (acto de libertad pre-individual) tiene una obvia dificultad. El artículo propone una reinterpretación que la evitaría, aunque desdramatizando un tanto el tentador alcance enigmático de la propuesta kantiana.

El término “ambivalencia” cumple con varias de las funciones teóricas más relevantes tanto para el psicoanálisis como para su tesis fundacional: la del inconsciente.
