Modern semiotics is a branch of logics that formally defines symbol-based communication. In recent years, the semiotic classification of signs has been invoked to support the notion that symbols are uniquely human. Here we show that alarm-calls such as those used by African vervet monkeys (Cercopithecus aethiops), logically satisfy the semiotic definition of symbol. We also show that the acquisition of vocal symbols in vervet monkeys can be successfully simulated by a computer program based on minimal semiotic and neurobiological constraints. (...) The simulations indicate that learning depends on the tutor-predator ratio, and that apprentice-generated auditory mistakes in vocal symbol interpretation have little effect on the learning rates of apprentices (up to 80% of mistakes are tolerated). In contrast, just 10% of apprentice-generated visual mistakes in predator identification will prevent any vocal symbol to be correctly associated with a predator call in a stable manner. Tutor unreliability was also deleterious to vocal symbol learning: a mere 5% of “lying” tutors were able to completely disrupt symbol learning, invariably leading to the acquisition of incorrect associations by apprentices. Our investigation corroborates the existence of vocal symbols in a non-human species, and indicates that symbolic competence emerges spontaneously from classical associative learning mechanisms when the conditioned stimuli are self-generated, arbitrary and socially efficacious. We propose that more exclusive properties of human language, such as syntax, may derive from the evolution of higher-order domains for neural association, more removed from both the sensory input and the motor output, able to support the gradual complexification of grammatical categories into syntax.

This paper aims of is to present Richard Rorty’s Philosophy of Education, through his analysis of the education as being divided into two distinct processes: socialization and individualization. Thereafter, it is intended to show two critiques, of conservadorism and elitism, that are addressed to these processes. Finally, a redescription of the Rorty’s positions will be proposed, by assigning a reformist character to its apparent conservatism and a private character to the supposedly elitist individualization, in order to weaken the strength of (...) those critics.

In this chapter, Ricardo Silvestre and Alan Herbert offer a reconstruction of the Gītā’s concept of God with a focus on the relationship between God and the world. They try to explain the claim that the Gītā is panentheistic. This is done with the help of some key notions of contemporary metaphysics (such as ontological dependence and fundamentality) along with the Indic notion of prakṛti, considered as a metaphysical primitive denoting the intimate relationship that exists between matter and conscious (...) living beings on the one hand, and God on the other.

In this article, I present a defense of conceptual plausibility, understood as an epistemic way to qualify concepts that situates them between the merely possible and the actual. To show that there is such a thing as conceptual plausibility, I rely on what seems to lie at the heart of many uses of the phrase “plausible concept”: explanatory fruitfulness. To make an effective case for the claim that conceptual plausibility is of philosophical interest, I present an argument based on the (...) debate over the rationality of theistic belief and the concept of God. To show that conceptual plausibility is philosophically feasible, I first show that it cannot be reduced to propositional plausibility. Next, I offer a minimally precise characterization of conceptual plausibility; I approach this from a qualitative and comparative perspective as well. Finally, I show how these qualitative and comparative criteria of conceptual plausibility might be applied to the debate over the rationality of theistic belief and the concept of God. (shrink)

Any plausibly just market exchange must balance two conflicting moral considerations: non-worseness (Wertheimer, 1999) and euvoluntariness (true voluntariness; Munger, 2011). We propose an analytical theory of just market exchange that partly resolves this conflict.

The paper discusses Ricardo's relationship to Mill and Bentham. It discusses first the origins of the myth of Ricardo's dependence from Bentham through Mill, and Halévy's contribution to the freezing of such a myth. The paper reconstructs what were their shared political commitments and activities and the kind of specific political views and agenda that may be ascribed to Ricardo himself. The paper discusses then the question of Ricardo's adhesion to Benthamite ethics. It examines fragments in (...) Ricardo's correspondence with Maria Edgeworth and Francis Place, and adds fresh light on the issue by highlighting the partial overlapping between Bentham's ethics and the kind of intuitionism with theological consequentialism that Ricardo had learned from the Unitarian minister Thomas Belsham.

The so-called theory of karma is one of the distinguishing aspects of Hinduism and other non-Hindu south-Asian traditions. At the same time that the theory can be seen as closely connected with the freedom of will and action that we humans supposedly have, it has many times been said to be determinist and fatalist. The purpose of this paper is to analyze in some deepness the relations that are between the theory of karma on one side and determinism, fatalism and (...) free-will on the other side. In order to do that, I shall use what has been described as the best formal approach we have to indeterminism: branching time theory. More specifically, I shall introduce a branching time semantic framework in which, among other things, statements such as “state of affairs e is a karmic effect of agent a”, “a wills it to be the case that e” and “e is inevitable” could be properly represented.

The purpose of this paper is twofold. First, it aims at introducing the ontological argument through the analysis of five historical developments: Anselm’s argument found in the second chapter of his Proslogion, Gaunilo’s criticism of it, Descartes’ version of the ontological argument found in his Meditations on First Philosophy, Leibniz’s contribution to the debate on the ontological argument and his demonstration of the possibility of God, and Kant’s famous criticisms against the (cartesian) ontological argument. Second, it intends to critically examine (...) the enterprise of formally analyzing philosophical arguments and, as such, contribute in a small degree to the debate on the role of formalization in philosophy. My focus will be mainly on the drawbacks and limitations of such enterprise; as a guideline, I shall refer to a Carnapian, or Carnapian-like theory of argument analysis. (shrink)

A reconstruction of the philosophical, religious and political background of Ricardo's work as an economist.

The main claim of this study is that, contrary to Latour’s view about the need to leave aside epistemology to deal with anything valuable about science, Mario Bunge has consistently built up a detailed and thorough epistemology. The argumentative strategy will be to show that (a) it is not true that we have never been modern (b) epistemology is here to stay, and (c) Mario Bunge endorses a strong scientific realism, a brand of materialism, systemism and emergentism, including a moral (...) dimension (there are objective values like, truth, peace and justice that deserve to be respected). Then, Bunge’s realism rejects axiological neutrality making scientists responsible for their actions. Bunge has always been modern and keeps enriching his own views. (shrink)

Cette étude défend l’idée que, contrairement à l’opinion de Latour sur la nécessité de laisser de côté l’épistémologie pour traiter de tout ce qui a de la valeur pour la science, Mario Bunge a systématiquement construit une épistémologie détaillée et approfondie. La stratégie argumentative consistera à montrer (a) qu’il est faux que nous n’avons jamais été modernes (b) que l’épistémologie est là pour de bon et (c) que Mario Bunge soutient un réalisme scientifique fort, une version du matérialisme, du systémisme (...) et de l’émergentisme, comportant une dimension morale (il existe des valeurs objectives comme la vérité, la paix et la justice qui méritent d’être étudiées). Ensuite, le réalisme de Bunge rejette la neutralité axiologique rendant les scientifiques responsables de leurs actions. Bunge a toujours été moderne et continue à enrichir ses propres positions.

Few views are as widely held as the Standard View of Identity. Here I am concerned with minority views that depart from the standard account. First, I attempt to illuminate such views and the debates concerning them by identifying the principles of identity at issue, articulating some of the assumptions underlying the debates, and presenting some of the evidence used against the Standard View of Identity. Second, I enter two of these debates myself. I first defend two Non-Standard Views of (...) Identity from the charge that they violate a principle of identity, namely the Transitivity of Identity. I then present an overlooked consequence of another Non-Standard View of Identity that challenges the view on one of its own methodological principles. Third, I draw on recent work in ontological and parthood pluralism to show how one might be led to think that there is more than one way of being identical. That is, I show how one might be an identity pluralist. (shrink)

In this paper I try to answer four basic questions: (1) How the concept of God is to be represented? (2) Are there any logical principles governing it? (3) If so, what kind of logic lies behind them? (4) Can there be a logic of the concept of God? I address them by presenting a formal-logical account to the concept of God. I take it as a methodological desideratum that this should be done within the simplest existing logical formalism. I (...) start with first-order logic (FOL) with identity, and then show that its simplest modal extension (SQML, or the simplest quantified modal logic) is enough for us to formalize a minimally satisfactory theory of the concept of God. I focus exclusively on the monotheistic concept of God. (shrink)

Em analogia com outras discriminações, como o racismo ou o sexismo, o especismo é concebido como uma forma de discriminação moral com base na espécie. Em grande medida, a discussão contemporânea sobre a importância moral dos animais surgiu e desenvolveu-se em torno da crítica e da defesa do especismo. Este artigo oferece uma visão da discussão filosófica contemporânea sobre o especismo. Após uma breve introdução, apresenta-se uma definição de especismo e caracterizam-se vários tipos de especismo, sendo o Antropocentrismo o mais (...) relevante. Depois, expõe-se um argumento proeminente contra o Antropocentrismo: o argumento dos casos marginais. Por fim, algumas posições antropocêntricas são criticamente discutidas. (shrink)

It is a fact that there is ethical criticism about art. Art critics, the general public and even artists point out moral flaws in artworks while evaluating them. Philosophers, however, have maintained a hot debate on the meaning of such criticism. This debate can be understood as a disagreement about the kind of relation between the artistic value of artworks and their alleged moral value. While some claim that moral value can contribute to artistic value (moralism), others claim that there (...) cannot be such a contribution (autonomism). Since at least some works of architecture are artworks, that debate also concerns architecture. A moderate moralist view claims that some works of architecture have moral flaws/merits that bear on their artistic evaluation. In an apparently promising version, the contention is that some moral flaws/merits are aesthetically relevant. In this paper I argue against such contention and defend an autonomist view. Following some taxonomy remarks I distinguish the views in the debate and present two points in favour of autonomism: its simplicity and not having the burden of proof. Then I discuss Carroll’s merited response argument for moralism and I argue that in its best interpretation either it begs the question against autonomism or it is compatible with it. I conclude with some possible objections that may help further investigations on the subject. (shrink)

O objetivo deste artigo é analisar o conceito de yoga da Bhagavad-gītā. Cinco concepções de yoga encontradas no texto são descritas: yoga enquanto disciplina ou prática, yoga enquanto disciplina qualificada, yoga enquanto estado mental de equanimidade e renúncia, yoga enquanto estado de união e yoga enquanto poder místico. As relações existentes entre essas concepções são explicitadas e o que podemos chamar de a estrutura do yoga na Bhagavad-gītā é pormenorizada.

Detractors of Searle’s Chinese Room Argument have arrived at a virtual consensus that the mental properties of the Man performing the computations stipulated by the argument are irrelevant to whether computational cognitive science is true. This paper challenges this virtual consensus to argue for the first of the two main theses of the persons reply, namely, that the mental properties of the Man are what matter. It does this by challenging many of the arguments and conceptions put forth by the (...) systems and logical replies to the Chinese Room, either reducing them to absurdity or showing how they lead, on the contrary, to conclusions the persons reply endorses. The paper bases its position on the Chinese Room Argument on additional philosophical considerations, the foundations of the theory of computation, and theoretical and experimental psychology. The paper purports to show how all these dimensions tend to support the proposed thesis of the persons reply. (shrink)

Animal replaceability is supposed to be a feature of some consequentialist theories, like Utilitarianism. Roughly, an animal is replaceable if it is permissible to kill it because the disvalue thereby caused will be compensated by the value of a new animal’s life. This is specially troubling since the conditions for such compensation seem easily attainable by improved forms of raising and killing animals. Thus, grounding a strong moral status of animals in such theories is somewhat compromised. As is, consequently, their (...) position as an alternative to rights-based theories in animal ethics. Recognising this, some utilitarians tried to disassociate utilitarianism and replaceability. I will here add my voice to this project. However, instead of seeing the culprit in the usual suspects (hedonism, maximisation or the total view), I advance a new proposal. After identifying that the compensating value for a disvaluable action has to be its consequence, I present a restriction on consequences: consequences of sequences of actions cannot be consequences of the isolated actions in the sequences. Given this, the main argument is simple: killing an animal is permissible only if the the value of the new animal’s life is a consequence of the killing; but this value is a consequence of a sequence of actions which involves the killing plus some additional actions; therefore, since, via the restriction, such value is not a consequence of the killing, it is irrelevant to its normative status. I then present two further motivations for the restriction: firstly, it prevents the value of conditional actions from trivially influencing the value of the actions on which they are conditional; secondly, it is useful – even if not a complete solution – to reply other objections to consequentialism: the accordion effect of action and the cluelessness problem. I finally consider a couple of objections. (shrink)

he general theme of this paper is the issue of formalization in philosophy; in a more specific way, it deals with the issue of formalization of arguments in analytic philosophy of religion. One argument in particular – Anselm’s Proslogion II ontological argument – and one specific attempt to formalize it – Robert Adams’ formalization found in his paper “The Logical Structure of Anselm’s Arguments”, published in The Philosophical Review in 1971 – are taken as study cases. The purpose of the (...) paper is to critically analyze Adams’ formalization with the intent to shed some light on the following questions: What are the virtues of formally analyzing arguments and the contributions, if any, of such an enterprise to the debate on Anselm’s argument? Which lessons can Adam’s work teach us about the dangers and limitations of formalization? Do these virtues and dangers teach us something about analysis of arguments in general? (shrink)

This paper is a follow-up of the first part of the persons reply to the Chinese Room Argument. The first part claims that the mental properties of the person appearing in that argument are what matter to whether computational cognitive science is true. This paper tries to discern what those mental properties are by applying a series of hypothetical psychological and strengthened Turing tests to the person, and argues that the results support the thesis that the Man performing the computations (...) characteristic of understanding Chinese actually understands Chinese. The supposition that the Man does not understand Chinese has gone virtually unquestioned in this foundational debate. The persons reply acknowledges the intuitive power behind that supposition, but knows that brute intuitions are not epistemically sacrosanct. Like many intuitions humans have had, and later deposed, this intuition does not withstand experimental scrutiny. The second part of the persons reply consequently holds that computational cognitive science is confirmed by the Chinese Room thought experiment. (shrink)

No artigo “O vegetarianismo como obrigação ética” (Crítica, 10 de Setembro de 2015), Moutinho defende que o vegetarianismo é uma obrigação moral. Fá-lo argumentando por duas vias: que o estatuto moral dos animais é incompatível com serem usados pelos humanos para alimentação; e que o vegetarianismo é consequência do nosso dever em preservar o equilíbrio ecológico do planeta. O meu objectivo neste artigo é mostrar que os argumentos apresentados são insuficientes para estabelecer o vegetarianismo como obrigação moral.

The terms “model” and “model-building” have been used to characterize the field of formal philosophy, to evaluate philosophy’s and philosophical logic’s progress and to define philosophical logic itself. A model is an idealization, in the sense of being a deliberate simplification of something relatively complex in which several important aspects are left aside, but also in the sense of being a view too perfect or excellent, not found in reality, of this thing. Paraconsistent logic is a branch of philosophical logic. (...) It is however not clear how paraconsistent logic can be seen as model-building. What exactly is modeled? In this paper I adopt the perspective of looking at a particular instance of paraconsistent logic—paranormal modal logic—which might be seen as a model of a specific kind of agent: inductive agents. After ntroducing what I call the highlevel and low-level models of inductive agents, I analyze the extent to which the above-mentioned idealizing features of model-building appear in paranormal modal logic and how they affect its philosophical significance.

This paper aims at examining the issue of the role of supreme being theology in non-Abrahamic traditions. According to the dominant view in contemporary philosophy of religion, the philo-sophical project of inferring divine properties from the concept of God as a maximally perfect being, usually called supreme being theology, is an exclusivity of the Abrahamic traditions. In attempting to question this view, I investigate the developments of two key-concepts of Vedāntatradition –the concepts of Brahman (literally, the greatest) and Bhagavān (literally, (...) the possessor of all excellences) –in thethought of three famous vedantins: Śaṅkara, Rāmānuja and Jīva.

Neste trabalho, é apresentada uma investigação do que poderia ser chamado de formalização lógica do processo de mudança de teorias devido a anomalias. Por anomalia entende-se um fato observado que faz parte do escopo explanatório de uma teoria, mas que vai de encontro à previsão da mesma. Uma abordagem clássica para restaurar o poder explicativo de uma teoria ameaçada por uma anomalia é a postulação de hipóteses novas e provisórias que, em conjunto com as demais hipóteses auxiliares originais, sejam capazes (...) de resolver a anomalia. Após chegar à algumas conclusões sobre a estrutura de tal processo, propomos um framework lógico multimodal e não-monotônico capaz de representar alguns aspectos-chave dessa faceta importante da dinâmica de teorias científicas. Devido à necessidade de acomodar hipóteses provisórias incompatíveis, esse framework incorpora uma forma fraca de paraconsistência. Como um estudo de caso, analisamos o comportamento anômalo do planeta Urano que ameaçou a mecânica celeste Newtoniana por mais de meio século e ensejou a descoberta do planeta Netuno. -/- In this work, an investigation of what could be called the logical formalization of the theory change process due to anomalies is presented. An anomaly is understood as an observed fact that is part of the explanatory scope of a theory, but that goes against its prediction. A classic approach to restoring the explanatory power of a theory threatened by an anomaly is to postulate new and provisional hypotheses that, together with the other original auxiliary hypotheses, are capable of resolving the anomaly. After reaching some conclusions about the structure of such a process, we propose a multimodal and non-monotonic logical framework capable of representing some key aspects of this important facet of the dynamics of scientific theories. Due to the need to accommodate incompatible provisional hypotheses, this framework incorporates a weak form of paraconsistency. As a case study, we analyze the anomalous behavior of the planet Uranus that threatened Newtonian celestial mechanics for more than half a century and prompted the discovery of the planet Neptune.

Ao mesmo tempo que o malogro da assim chamada teoria clássica dos conceitos - de acordo com a qual definições são a maneira apropriada de caracterizar conceitos - é um consenso, a filosofia metafísica da religião parece ainda lidar com o conceito de Deus de forma predominantemente definicional. Podemos então nos perguntar: Seria esse malogro suficiente para inviabilizar uma caracterização definicional do conceito de Deus? Meu propósito central neste artigo é responder essa pergunta. Adoto uma ênfase representacional. Em outras palavras, (...) desejo analisar até que ponto os problemas mais importantes levantados contra a teoria clássica dos conceitos afetam uma abordagem definicional-representacional do conceito de Deus. Como resultado desse esforço, mostro que as críticas à teoria clássica que ameaçam tal abordagem dependem da pluralidade característica ao contexto inter-religioso, que por si só cria outros problemas.

This work, in English "Struggle for power, organic crisis and judicial independence", has its origin in research academics of the IAEN carried out to provide expert advise to the Inter American Court of Human Rights in the case Quintana and others (Supreme Court of Justice) vs the State of Ecuador. The research is about the nature of the evolution of the ecuadorian state, the dynamics of its institutions, its players, parties, laws, its factors of instability, the way rights have been (...) deployed since the return to democracy in 1979, those who have benefited from neoliberal democracy and those who have paid the costs, and where in all this was the Supreme Court of Justice. The Introduction takes a look at this origin of the work and its intellectual import, provides a brief characterization of the Inter American Sistem of Human Rights Protection, how the Quintana Case fits within it, and an overview of the chapters and their logic. The first chapter analyzes the institutional and sociological factors that have contributed to Ecuador's historically unstable state, based primarily in an antagonistic struggle for power between the Executive and Legislative branches. The second chapter analyzes the economic and political factors that provoked an organic crisis, or crisis of hegemony, between 1997 and 2007 in Ecuador. The third chapter analyzes the evolution of the way in which judges are selected in Europe, the outcomes they have generated, and how they compare with the ecuadorian systems of judge selection in terms of securing judicial independence. The fourth chapter develops a theory of judicial independence in democracy and analyzes how Ecuador measures up to that standard, from when it became a neoliberal minimal democracy in 1981, to when it became a neoliberal false democracy as a consequence of instalation of a system evidently lacking in the people's support under the guise of the 1998 Constitution and its system of judge selection, and the new democratic horizons set by the 2008 Constitution, and the judicial system that springs from it.

The thesis develops solutions to two main problems for mental realism. Mental realism is the theory that mental properties, events, and objects exist, with their own set of characters and causal powers. The first problem comes from the philosophy of science, where Psillos proposes a notion of scientific realism that contradicts mental realism, and consequently, if one is to be a scientific realist in the way Psillos recommends, one must reject mental realism. I propose adaptations to the conception of scientific (...) realism to make it compatible with mental realism. In the process, the thesis defends computational cognitive science from a compelling argument Searle can be seen to endorse but has not put forth in an organized logical manner. A new conception of scientific realism emerges out of this inquiry, integrating the mental into the rest of nature. The second problem for mental realism arises out of non-reductive physicalism- the view that higher-level properties, and in particular mental properties, are irreducible, physically realized, and that physical properties are sufficient non-overdetermining causes of any effect. Kim’s Problem of Causal Exclusion aims to show that the mental, if unreduced, does no causal work. Consequently, given that we should not believe in the existence of properties that do not participate in causation, we would be forced to drop mental realism. A solution is needed. The thesis examines various positions relevant to the debate. Several doctrines of physicalism are explored, rejected, and one is proposed; the thesis shows the way in which Kim’s reductionist position has been constantly inconsistent throughout the years of debate; the thesis argues that trope theory does not compete with a universalist conception of properties to provide a solution; and shows weakness in the Macdonald’s non-reductive monist position and Pereboom’s constitutional coincidence account of mental causation. The thesis suggests that either the premises of Kim’s argument are consistent, and consequently his reductio is logically invalid, or at least one of the premises is false, and therefore the argument is not sound. Consequently, the Problem of Causal Exclusion that Kim claims emerges out of non-reductive physicalism does not force us to reject mental realism. Mental realism lives on. (shrink)

The semantic paradoxes are a family of arguments – including the liar paradox, Curry’s paradox, Grelling’s paradox of heterologicality, Richard’s and Berry’s paradoxes of definability, and others – which have two things in common: first, they make an essential use of such semantic concepts as those of truth, satisfaction, reference, definition, etc.; second, they seem to be very good arguments until we see that their conclusions are contradictory or absurd. These arguments raise serious doubts concerning the coherence of the concepts (...) involved. This article will offer an introduction to some of the main theories that have been proposed to solve the paradoxes and avert those doubts. Included is also a brief history of the semantic paradoxes from Eubulides to Tarski and Curry. (shrink)

"David Ricardo has been acclaimed - or vilified - for merits he would never have dreamt of, or sins for which he was entirely innocent. Entrenched mythology labels him as a utilitarian economist, an enemy of the working class, an impractical theorist, a scientist with 'no philosophy at all' and the author of a formalist methodological revolution. Exploring a middle ground between theory and biography, this book explores the formative intellectual encounters of a man who came to economic studies (...) via other experiences, thus bridging the gap between the historical Ricardo and the economist's Ricardo. The chapters undertake a thorough analysis of Ricardo's writings in their context, asking who was speaking, what audience was being addressed, with what communicative intentions, using what kind of lexicon and communicative conventions, and starting with what shared knowledge. The work opens in presenting the different religious communities with which Ricardo was in touch. It goes on to describe his education in the leading science of the time - geology - before he turned to the study of political economy. Another chapter discusses five 'philosophers' - students of logic, ethics and politics - with whom he was in touch. From correspondence, manuscripts and publications, the closing chapters reconstruct, firstly, Ricardo's ideas on scientific method, the limits of the 'abstract science' and its application, secondly, his ideas on ethics and politics and their impact on strategies for improving the condition of the working class. This book sheds new light on Ricardian economics, providing an invaluable service to readers of economic methodology, philosophy of economics, the history of economic thought, political thought and philosophy. Sergio Cremaschi is a former Reader of Moral Philosophy at the 'Amedeo Avogadro' University at Vercelli"--. (shrink)

The paper is a comparative study of the methodologies of Malthus and Ricardo. Its claims are: (i) economic laws almost always admit of exceptions for Malthus; for Ricardo even contingent predictions allow no exception apart from random temporary variations; (ii) both rely on the prestigious Newtonian paradigm, while interpreting it according to two distinct methodological traditions (the one deriving from MacLaurin, the other from Priestley); (iii) the choice of stressing what happens during intervals or in permanent states leads (...) to opposing definitions of the main problem of economic science in so far as equilibrium is always already given for Ricardo and is never given for Malthus; (iv) their use of the ambiguous notion of "tendency" leaves unclear for both the degree of predictive power with which theories are endowed; (v) what both share is the idea of a natural order and this idea is the source of both shortcomings and endless disagreement. -/- .
