This monograph is a defence of the Fregean take on logic. The author argues that Frege ́s projects, in logic and philosophy of language, are essentially connected and that the formalist shift produced by the work of Peano, Boole and Schroeder and continued by Hilbert and Tarski is completely alien to Frege's approach in the Begriffsschrift. A central thesis of the book is that judgeable contents, i.e. propositions, are the primary bearers of logical properties, which makes logic embedded in our (...) conceptual system. This approach allows coherent and correct definitions of logical constants, logical consequence, and truth and connects their use to the practices of rational agents in science and everyday life.

The purpose of this paper is twofold: first we outline a version of non-descriptivism, ‘minimal expressivism’, leaving aside certain long-standing problems associated with conventional expressivist views. Second, we examine the way in which familiar expressivist results can be accommodated within this framework, through a particular interpretation that the expressive realm lends to a theory of meaning. Expressivist theories of meaning address only a portion of the classical problems attributed to this position when they seek to explain why the expressions they (...) deal with have a given meaning. A position can nevertheless be termed ‘expressivist’ – in the minimal sense that we favor – based simply on the following key features of the meaning of these expressions: they can be used as functions of propositions, and they are not used to describe the way the world is.

Frank Plumpton Ramsey (1903–30) made seminal contributions to philosophy, mathematics and economics. Whilst he was acknowledged as a genius by his contemporaries, some of his most important ideas were not appreciated until decades later; now better appreciated, they continue to bear an influence upon contemporary philosophy. His historic significance was to usher in a new phase of analytic philosophy, which initially built upon the logical atomist doctrines of Bertrand Russell and Ludwig Wittgenstein, raising their ideas to a new level of (...) sophistication, but ultimately he became their successor rather than remain a mere acolyte.

In this Interview, Professor Robert B. Brandom answered ten detailed questions about his philosophy of Rational Pragmatism and Semantic Expressivism, grouped into four topics. 1. Metaphysics and Anthropology, 2. Pragmatics and Semantics, 3. Epistemic Expressivism and 4. Philosophy of Logic. With his careful answers Professor Brandom offers many additional insights into his rigorously constructed account of the relationship “between what we say and think, and what we are saying and thinking about” around the human practice of asking for and giving (...) reasons. A final, additional question pointed at a principal motivation for putting together the present issue: how to reconcile Wittgenstein’s assertion that philosophy must not proffer any theories with the very explicit system of explanations Brandom has constructed. This same issue is addressed to some extent already in Professor Brandom’s new article contained in this issue, but his answer, asserting that he does not proffer a theory but only makes explicit what is already there, might be seen as an unambiguous statement of the continuous presence of a contested Wittgensteinian principle in Brandom’s work.

Frank Plumpton Ramsey, Cambridge mathematician and philosopher, was one of the most brilliant people of his generation. He lived in an extraordinarily stimulating milieu, surrounded by figures such as Russell, Whitehead, Keynes, Moore, and Wittgenstein. Ramsey's highly original papers on the foundations of mathematics, probability, economics, philosophy of science and the theory of knowledge were very influential in the 20th century and are still widely discussed in the 21st. Perhaps two of Ramsey's achievements outshine all the rest. One is his (...) treatment of the theoretical terms of scientific theories and the other is his deflationary account of truth. In 'Theories' he showed that, for any theory, it is always possible to offer an empirically equivalent one that does not contain theoretical terms by re-expressing it in what later became known as 'Ramsey sentences'. His account of truth was rediscovered in the 1960s and is now known as the 'prosentential' theory of truth. This collection of eleven new papers, specially written to commemorate his centenary, answers a crying need for more secondary literature on Frank Ramsey. Nearly all the aspects of Ramsey's work are examined: his logic, philosophy of mind, philosophy of science, metaphysics, epistemology, pragmatism, economics, and the mutual influences between Ramsey and Wittgenstein. The book will be eagerly welcomed by those working in many branches of analytic philosophy and beyond. (shrink)

This paper is an attempt to convince anti-realists that their correct intuitions against the metaphysical inflationism derived from some versions of mathematical realism do not force them to embrace non-standard, epistemic approaches to truth and existence. It is also an attempt to convince mathematical realists that they do not need to implement their perfectly sound and judicious intuitions with the anti-intuitive developments that render full-blown mathematical realism into a view which even Gödel considered objectionable. I will argue for the following (...) two theses: that realism, in its standard characterization, is our default position, a position in agreement with our pre-theoretical intuitions and with the results of our best semantic theories, and that most of the metaphysical qualms usually related to it depends on a poor understanding of truth and existence as higher-order concepts.

The purpose of this paper is to show that, pace (Field, 2009), MacFarlane’s assessment relativism and expressivism should be sharply distinguished. We do so by arguing that relativism and expressivism exemplify two very different approaches to context-dependence. Relativism, on the one hand, shares with other contemporary approaches a bottom–up, building block, model, while expressivism is part of a different tradition, one that might include Lewis’ epistemic contextualism and Frege’s content individuation, with which it shares an organic model to deal with (...) context-dependence. The building-block model and the organic model, and thus relativism and expressivism, are set apart with the aid of a particular test: only the building-block model is compatible with the idea that there might be analytically equivalent, and yet different, propositions.

The aim of this paper is to discuss Kripkc?s reasons for declaring the existence of both necessary a posteriori as well as contingent a priori statements, thus breaking the traditional extensional coincidence of the two pairs of concepts:necessary?contingent and a priori?a posteriori. As I shall argue, there is no reason, from Kripke?s work at least, to reject the usual picture of the topic The appeal ot his arguments rests on the ambiguity with which his expressions are used and on the (...) introduction o\ new senses for old notions. This does not mean, however, that all Knpke?s and Putnam?s intuitions on singular terms and natural kind nouns are wrong. Once Kripke?s ideas are properly uudeistood, they are much moreharmless then they are presented to be and they do not pose a threat to traditional relations relations between modal and epistemological categories.

El artículo ofrece una caracterización de las constantes lógicas, [CL], analizando el significado de las expresiones que son sus contrapartidas en el lenguaje natural. [CL] recoge los rasgos sintácticos, semánticos y pragmáticos individualmente necesarios y conjuntamente suficientes para que una expresión sea una constante lógica. Se obtendrá la siguiente conclusión: que la lista de las expresiones que habitualmente se consideran constantes lógicas no comparten rasgos relevantes desde el punto de vista del significado que justifiquen su tratamiento como un grupo homogéneo. (...) Sólo algunos usos del condicional, de la negación y de ciertos cuantificadores son constantes lógicas genuinas. (shrink)

This volume comprises a lively and thorough discussion between philosophers and Tyler Burge about Burge's recent, and already widely accepted, position in the theory of meaning, mind, and knowledge. This position is embodied by an externalist theory of meaning and an anti-individualist theory of mind and approach to self-knowledge. The authors of the eleven papers here expound their versions of this position and go on to critique Burge's version. Together with Burge's replies, this volume offers a major contribution to contemporary (...) philosophy. (shrink)

We propose a new approach to conditional donkey sentences that allows us to face successfully the often called proportion problem. The main ingredients of the proposal are van Benthem's generalized quantifier approach to conditionals, and Barwise's situation semantics. We present some experimental data supporting our proposal.

This paper deals with Ramsey's theory of truth and its aim is twofold: on the one hand, it will explain what position about truth Ramsey actually defended, and, on the other hand, we will pursue Ramsey's insight in the 20th Century. When the name of Frank Ramsey is mentioned, one of the things that comes to mind is the theory of truth as redundancy. In the following pages we will argue that Ramsey never supported such a theory, but rather an (...) analysis of truth noticeably similar to the prosentential account. In fact, the very word "pro-sentence" appears for the first time in the 20th Century in Ramsey's unfinished work "The nature of truth," written around 1929. Besides, we will show that the prosentential account of truth is a neglected trend throughout the history of analytic philosophy, even though relevant analytic philosophers, such as Prior, Strawson, Williams, Grover, and Brandom, have endorsed it.

The background of this paper is what I call “pragmatic inferentialism,” a view that I attribute to Robert Brandom. Here, I develop Brandom’s view and argue that it is a kind of subject naturalism, in Price’s sense, and that the charge of idealism sometimes addressed against it is unwarranted. Regarding, I show that pragmatic inferentialism finds support from evolutionary psychology and developmental psychology. Regarding, I present what I call “level 0 expressivism,” which I take to be the semantic counterpart of (...) some aspects of evolutionary psychology and developmental psychology. Besides, I resort to Brandom’s defense of Hegel’s conceptual realism. The conclusion of the paper is a vindication of objective truth in the inferentialist framework. (shrink)

El propósito de este artículo es mostrar que las llamadas "teorías de la identidad psiconeural" no tienen la estructura lógica de una teoría genuina de la identidad. Un operador de identidad genuino es un operador de segundo orden, o de órdenes superiores, que convierte predicados n-ádicos en predicados n-1-ádicos. Si las teorias de la identidad psiconeural no son, en realidad, teorías de la identidad, entonces la críticas habituales que usan la Ley de Leibniz y otros rasgos que se relacionan con (...) la identidad no tienen ningún efecto. Así, dos serán las conclusiones: (i) que las llamadas "teorías de la identidad psiconeural" deben de reformularse, de manera que expresen claramente su contenido, y (ii) que las críticas utizadas hasta ahora contra ellas no consiguen su objetivo.The aim of this paper is to show that the so-called "theories of psichoneural identity" do not possess the logical structure of a genuine theory of identity. The identity operator is a second- or higher-order operator that converts n-adic predicates into n-1-ádic ones. If the so-called "theories of psichoneural identity" are not theories of identity at all, then two conclusions follow: (i) these theories of the mind-body relation should state their contents in a more appropiate way, and (ii) the usual criticisms against them, which bear on some features that all idetity theories must hold, as for instance Leibniz Law, leave them untouched.

Este artículo debate algunas de las cuestiones que el Profesor Puntel discute en su conferencia “‘verdad’ como concepto ontológico-semántico” (2007). La conferencia de Puntel toca numerosos aspectos de la noción de verdad; de entre ellos, hemos aislado dos conjuntos temáticos. El primero tiene que ver con cuestiones preliminares acerca de la verdad que el Prof. Puntel discute antes de presentar su posición. El segundo está relacionado con la posición particular que Puntel defiende y en concreto con su crítica a las (...) teorías pro-oracionales. El primer asunto tiene relevancia porque las cuestiones preliminares en teoría de la verdad constriñen el desarrollo posterior de la teoría de manera determinante; el segundo aspecto tiene relevancia porque la crítica de Puntel encierra ciertos malentendidos de fondo que desdibujan su propia posición y le impiden tener el alcance que el Prof. Puntel le atribuye.

We identify two senses of ‘pragmatics’ and related terms that give rise to two different methods of propositional individuation. The first one is the contextualist approach that essentially acknowledges contextual information to take part in the determination of what is said by the utterance of a sentence. In this sense, Pragmatics relies on the Principle of Compositionality and interprets propositions as structured entities. It epitomises the Building-block Model of Propositional Individuation. The general approach that makes what the agents do the (...) grounding level of philosophical and linguistic analysis characterizes the second sense, Pragmatism. It finds its clearest expression in Peirce’s Pragmatist Maxim, and it relies on the Fregean Principle of Context, and supports a view of propositions as unstructured entities. This is the Organic Model of Propositional Individuation. There is a test, the Analytic Equivalence Test, that tells apart the two models. According to it, the answer to the question whether a theory makes room for different but analytically equivalent propositions determines the model the theory belongs in. A positive answer classifies the theory as belonging to the building-block model; a negative answer allocates the theory within the organic model. (shrink)

Hintikka’s semantic approach to meaning, a development of Wittgenstein’s view of meaning as use, is the general theme of this chapter. We will focus on the analysis of quantified sentences and on the scope of the principle of compositionality and compare Hintikka’s take on these issues with that of Frege. The aim of this paper is to show that Hintikka’s analysis of quantified expressions as choice functions, in spite of its obvious dissimilarities with respect to the higher-order approach, is actually (...) very close to the Fregean stance on compositionality and context dependence. In particular, we will defend that the Fregean approach to quantifiers is unavoidably linked to the idea that quantified expressions are context-dependent, and therefore should not be conceived under the traditional inside-out model for analysis.
