Empiricist philosophers like Carnap invoked analyticity in order to explain a priori knowledge and necessary truth. Analyticity was “truth purely in virtue of meaning”. The view had a deflationary motivation: in Carnap’s proposal, linguistic conventions alone determine the truth of analytic sentences, and thus there is no mystery in our knowing their truth a priori, or in their necessary truth; for they are, as it were, truths of our own making. Let us call this “Carnapian conventionalism”, conventionalismC and cognates for (...) short. This conventionalistC explication of the a priori has been the target of sound criticisms. Arguments like Quine’s in “Truth by Convention” are in our view decisive: the truth of conventionalismC requires that the class of logical truths and logical validities be reductively accounted for as conventionally established; however, no such reduction is forthcoming, because logic is needed to generate the entire class from any given set of conventions properly so-called. Granted that conventionalismC is untenable, we want to take issue with a different, usually made criticism. Although the argument uncovers some difficulties for the way conventionalist claims are defended by some of its advocates, we will try to show that it fails. The criticism thus stands in the way of a proper appreciation of why the Carnapian account of the a priori is not correct. We will try to illustrate this by showing that the criticism we will dispute would dispose of conventionalist claims not only regarding philosophically problematic cases – logical and mathematical truths –, but also regarding cases for which they have some prima facie plausibility. One such case is that of truths that follow from mere abbreviations, “nominal” definitions; ‘someone is a bachelor if and only if he is an unmarried adult male’ can serve at this point for illustration. We will try to articulate a clear sense in which the contents of assertion such as this can be truths by convention. We do not need to prove that a conventionalist claim is true in those cases; it is enough for us to show that it is intelligible, for the arguments we will confront question even this. (shrink)

This paper argues for a conditional claim concerning a famous argument—developed by Church in elucidation of some remarks by Frege to the effect that the bedeutung of a sentence is the sentence’s truth-value—the Frege–Gödel–Church argument, or FGC for short. The point we make is this :if, and just to the extent that, Arthur Smullyan’s argument against Quine's use of FGC is sound, then essentially the same rejoinder disposes also of Davidson's use of FGC against ‘correspondence’ theories of truth. We thus (...) dispute a contention by Professor Davidson that it is coherent to accept that Smullyan’s rejoinder takes away the force of Quine’s version of FGC, while still consistently using FGC to establish that if true sentences (or utterances) correspond to anything, they all correspond to the same thing. We show that the differences between the cases discussed by Smullyan and Davidson’s version of FGC on which Davidson relies for his contention are irrelevant to the point under dispute. (shrink)

This paper is partly inspired by a well-known debate between Ruth Barcan Marcus, Terence Parsons and W. V. 0. Quine in the sixties> concerning the extent to which Quantified Modal Logic is committed to Essentialism; the issue nevertheless goes back to the origins of "analytic philosophy'', to the reflections of Frege, Russell, and the earlier Wittgenstein on the nature of logic. By elaborating on a suggestion by Quine, we purport to show that there is a relevant and interesting way to (...) look at the ontological commitments of logical systems such that they are stronger than they are usually taken to be.

Timothy Williamson has defended the claim that any philosophically satisfying conception of modality that encompasses possible worlds semantics (PWS) commits us to the Barcan Formula. His argument depends on the assumption that the domain of what there is (the domain of the actual world) has to be identified with the domain D(@), where @ is the index or possible world that in PWS represents , or stands for , the actual world. I work out an interpretation of the relation between (...) PWS and possible worlds terminology that makes it plausible to reject that assumption. (shrink)

Necessitism about individuals claims that necessarily every individual necessarily exists. An analogous necessitist thesis attributes necessary existence to properties and relations. Both theses have been defended by Williamson. Furthermore, Williamson specifically argues against the hybrid conjunction of first-order contingentism and higher-order necessitism; a combination that would bring about additional drawbacks. I work out a defence of the hybrid combination, including some replies to Williamson’s additional objections. Considerations of ontological parsimony and pre-theoretical intuitions favour the hybrid view over necessitism at all (...) orders. (shrink)

I deal here with one of Boghossian’s arguments against content externalism, related to our inferential rationality (to use his term). According to his reasoning, the apriority of our logical abilities is inconsistent with certain externalist assumptions. Nevertheless, the problem constitutes an important challenge for any theory of content, not just for externalism. Furthermore, when we examine what internalists may propose to solve the problem, we see that externalists have at their disposal a more promising repertoire of possible replies than internalists. (...) In that sense, insofar as Boghossian’s scenario is relevant to the debate externalism/internalism, it can be seen (against Boghossian’s original intention) as providing additional evidence for content externalism.

Hume argued that inductive inferences do not have rational justification. My aim is to reject Hume’s argument. The discussion is partly motivated by an analogy with Carroll’s Paradox, which concerns deductive inferences.

But then the subject does not have (...) reasons for believing what she believes. I defend a moderate externalist account that seeks to partly accommodate that objection to the radical externalist proposal. It is based on an extension of Peacocke’s theory of concepts: possession conditions for predicative concepts standing for natural properties include (fallible) dispositions to project them to new cases in accordance with inductive inferential patterns.

En este artículo discuto el supuesto compromiso de la lógica modal cuantificada con el esencialismo. Entre otros argumentos, Quine, el más emblemático de los críticos de la modalidad, ha objetado a la lógica modal cuantificada que ésta se compromete con una doctrina filosófica usualmente considerada sospechosa, el esencialismo: la concepción que distingue, de entre los atributos de una cosa, aquellos que le son esenciales de otros poseidos sólo contingentemente.

I study to what extent Quine can be right about this specific issue. I defend some of his views by exploring an analogy between modal logic and standard first order logic. That serves to get a better understanding of the status of modal logic and its relation with logic in general. (shrink)

Kripke argued for the existence of necessary a posteriori truths, and tried to explain why some of them seem to be contingent.

I point out several difficulties for (i), and argue (...) that (ii) can oe blocked because of the existence of alternative accounts of the phenomenon. (shrink)

A common view about Moore’s Proof of an External World is that the argument fails because anyone who had doubts about its conclusion could not use the argument to rationally overcome those doubts. I agree that Moore’s Proof is—in that sense—dialectically ineffective at convincing an opponent or a doubter, but I defend that the argument (even when individuated taking into consideration the purpose of Moore’s arguing and, consequently, the preferred addressee of the Proof) does not fail. The key to my (...) defence is to conceive the Proof as addressed to subjects with a different epistemic condition. To sustain this view I formulate some hypothesis about the common general purpose of arguing and I defend that it can be fulfilled even when the addressee of an argument is not someone who disbelieves or doubts its conclusion.

Según Williamson, saber y creer son estados mentales, pero creer algo verdadero y creer justificadamente algo verdadero no lo son.

Presento aquí un problema para dicha teoría: impone limitaciones implausibles a los posibles usos de conceptos y expresiones lingüísticas. Describiré algunas opciones que tendría Williamson para evitar el (...) problema; pero sostendré que acarrean cierta dosis de arbitrariedad. (shrink)

I present an epistemological puzzle about perceptual knowledge and its relation to the evaluation of probabilities. It involves cases, concerning a given subject S and a proposition P in a determinate context, where apparently: S has perceptual knowledge of P; the epistemic justification S has for believing Not-P is much greater than her epistemic justification for believing P. If those two theses were true, the following very plausible epistemological principle would fail: If S knows P, then the epistemic justification S (...) has for believing Not-P is not greater than her epistemic justification for believing P. I offer a solution to the puzzle, which is compatible with basic intuitions and theses of orthodox Bayesianism. (shrink)

E. Machery and some collaborators have used survey data to criticize Kripke’s anti-descriptivism about proper names. I highlight a number of drawbacks in the tests of Machery et al.

Furthermore, their vignettes are inconsistent.

Tanto la Fórmula Barcan como la postulación de possibilia contradicen los juicios intuitivos preteóricos de la mayoría de los sujetos, favorables al actualismo sobre la naturaleza de los mundos posibles.

Kripke argued for the existence of necessary a posteriori truths and offered different accounts of why certain necessary truths seem to be contingent. One of these accounts was used by Kripke in an argument against the psychophysical identity thesis. I defend the claim that the explanatory force of Kripke's standard account of the appearance of contingency relies on the explanatory force of one of the more general accounts he also offers. But the more general account cannot be used to undermine (...) the psychophysical identity thesis. Specifically, a crucial feature in Kripke's standard account, which is needed to argue for dualism, is explanatorily superfluous. Alternative accounts that are similar to Kripke's original one but lack that trait would also explain the phenomenon. Consequently, the Kripkean dualist argument is blocked. /// Kripke ha argumentado que existen verdades necesarias a posteriori, y ha ofrecido diferentes explicaciones de por qué ciertas verdades necesarias parecen contingentes. Una de esas explicaciones se usaba en un argumento con el que Kripke criticaba la tesis de la identidad psicofísica.

Explicaciones alternativas, similares a la de Kripke pero que carezcan de ese rasgo, explicarían también el fenómeno. Como consecuencia, el argumento dualista kripkeano queda bloqueado. (shrink)

This work addresses the objections to analyticity and meaning atribution to single sentences included in Quines Two Dogmas of Empiricism.

They rely on the following thesis: (i) semantic holism that follows from the conjunction of Quines epistemic holism and verificationism is compatible with assignation of meaning to single sentences, which (...) in turn paves the way for a characterization of analyticity; (ii) epistemic holism and the related thesis that every true sentence is empirically revisable are objectionable if we accept criteria of individuation for truth bearers different from those assumed by Quine.

Igor Douven has offered an original reconstruction and defence of Putnam's model-theoretic argument against metaphysical realism. Douven's construal has notable exegetical virtues, since it makes sense of some assumptions in Putnam's argument which his opponents have considered question-begging or puzzling. In this article I provide an indirect defence of metaphysical realism, by showing why this new version of the anti-realist argument should also be rejected. The main problems in the Douven-Putnam argument come from ascribing to the realist a distorted view (...) of correspondence truth. The view entails that when no feature selects just one of all the possible interpretations of language the existence of an interpretation suffices to make true a theory. The sensible realist is not committed to this extreme conception of correspondence truth. /// Igor Douven ha presentado y defendido una reconstructión del argumento teórico-modelista de Putnam contra el realismo metafísico.

En este artículo proporciono una defensa indirecta del realismo metafisico, mostrando por qué debe también rechazarse el argumento antirrealista bajo esta nueva forma. Los problemas principales del argumento Douven-Putnam proceden de atribuir al realista una concepción distorsionada de la idea de verdad como correspondencia. Conforme a esa concepción, la ausencia de factores que seleccionen una única interpretación del lenguaje de entre las muchas posibles conlleva que la existencia de alguna interpretación ya es suficiente para hacer verdadera a una teoría que sea consistente.

The main goal of this paper is to contribute to the clarification of the dialectics between compatibilists and incompatibilists on free action. I describe a new incompatibilist position that has been neglected in the literature. I also provide a proper rationale for such a position. First, I present a justification for incompatibilism that is composed of an old idea and a new one. The old idea is the FRAP principle: freedom requires alternative possibilities. Compatibilists and incompatibilists alike usually share a (...) Key Assumption about how the open alternative possibilities allowed by indeterminism are supposed to support the libertarian case: the existence of alternative possibilities should make a metaphysically relevant difference concerning the control and/or the authorship of the agent over the action. The other component in the justification for incompatibilism is the rejection of the Key Assumption. Why to preserve FRAP when the Key Assumption is dropped? The answer has three parts: we have a strong pre-theoretical intuition in favour of FRAP; a crucial anti-libertarian argument, known as the Luck Argument, can be interpreted as showing that FRAP and the Key Assumption cannot both be true; the Luck Argument doesn't work when directed against FRAP itself.

En este artículo abordo uno de los problemas que pone de manifiesto la presunta incompatibilidad entre el externismo y el conocimiento que posee un sujeto sobre el contenido de sus pensamientos. El problema se basa en algunas supuestas consecuencias del externismo concernientes a la existencia de sustancias u objetos externos al sujeto pensante: si el externismo es a priori, entonces un sujeto puede saber a priori que existe el agua, meramente conociendo a priori su pensamiento sobre el agua. Las dos (...) respuestas compatibilistas principales que desarrollo explotan el papel desempeñado por la experiencia en el conocimiento a priori. Una vez se tiene en cuenta la experiencia requerida para poder tener los pensamientos relevantes resulta menos sorprendente que un sujeto pueda adquirir conocimiento a priori sobre la existencia del agua, o sobre una condición similar pero más débil que efectivamente se seguiría del externismo. I approach in this article one of the problems which purportedly would show the incompatibility of externalism and authoritative self-knowledge. The problem is based on some alleged consequences of externalism regarding the existence of substances or objects external to the thinker: if externalism is a priori, then a subject can know a priori that water exists by knowing a priori his thought about water. The two main compatibilist responses I work out exploit the role played by experience in a priori knowledge. Taking into account the experience required to entertain the relevant thoughts makes less puzzling that a subject could acquire a priori knowledge about water's existence, or about a weaker related condition which is the real commitment of externalism.

Según el particularismo semántico modal la función referencial de los términos singulares —también cuando aparecen en enunciados modales— es irreducible mediante funciones descriptivas y lógicas.
