Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

Contra an expanding number of deflationary commentators onWittgenstein, I argue that philosophical questions about meaningare meaningful and that Wittgenstein gave us ample reason tobelieve so. Deflationists are right in claiming that Wittgensteinrejected the sceptical problem about meaning allegedly to befound in his later writings and also right in stressing Wittgenstein''s anti-reductionism. But they are wrong in taking these dismissals to entail the end of all constructive philosophizing about meaning. Rather, I argue, the rejection of the sceptical problem requires that we (...) abandon the questions that philosophers have traditionally addressed and that we replace them with more appropriate ones, to which constructive answers are forthcoming. However, though quietism is not the only alternative to reductionism, the rejection of reductionism does oblige us seriously to revise our sense of what constructive philosophy can achieve. (shrink)

According to Barry Stroud, Wittgenstein thought that language is social only in this minimal way: we cannot make sense of the idea of someone having a language unless we can describe her as using signs in conformity with the linguistic practices of some community. Since a solitary person could meet this condition, Stroud concludes that, for Wittgenstein, solitary languages are possible. I argue that Wittgenstein in fact thought that language is social in a much more robust way. Solitary languages are (...) not possible because we cannot make sense of the idea of someone having a language unless we can think of her as actively participating in the linguistic practices that fix the standards governing the applications of her words.

This paper highlights the importance of inter-relationships between language, context, practice and interpretation. These inter-relationships should be of interest to AI researchers working in multi-disciplinary fields such as knowledge based systems, speech and vision. Attention is drawn to the importance of Part II, Section II of Wittgenstein'sPhilosophical Investigations for understanding the enormous complexity of the concept of seeing and how it is woven into an understanding of language and of human relations.

Since the rise of modern natural science there has been deep tension between the conceptual and the natural. Wittgenstein's discussion of how we learn a sensation-language contains important resources that can help us relieve this tension. The key here, I propose, is to focus our attention on animal nature, conceived as partially re-enchanted. To see how nature, so conceived, helps us relieve the tension in question, it is crucial to gain a firm and detailed appreciation of how the primitive-instinctive, a (...) central part of animal nature, actually serves the conceptual. I offer such an appreciation by closely examining §244 of the Philosophical Investigations and Peter Winch's discussion of it. The general aim is to bring out a certain kind of Wittgensteinian “naturalism”, a “naturalism” that is fully alive to the rootedness of conceptuality in nature. A concomitant aim is to illustrate the truth of Wittgenstein's saying that in philosophy one often has to pay close attention to details. (shrink)

A woman is listening to Sinatra before work. As she later describes it, ‘suddenly from nowhere I could hear my mother singing along to it … I was there again home again, hearing my mother … God knows why I should choose to remember that … then, to actually hear her and I had this image in my head … of being at home … with her singing away … like being transported back you know I got one of those (...) … like shivery feelings really suddenly’ (Anderson 2004, 9-10). An older couple, discussing their honeymoon forty years ago, each say that they can’t remember the show they saw, until through iterative, puzzled cross-cuing they finally get there – ‘Desert Song, that’s it’ (Harris et al 2011, 292). An elderly English veteran of a prisoner of war camp in Japan, finishing up morning tea with a young Japanese social scientist interested in reconciliation, suddenly calls out loudly - in Japanese - ‘stand to attention’. He stands to attention in front of her: like many of the men she interviews, he physically re-enacts fragments of that long-past world of the camp, bringing that absent past into this new present context with a visceral shock (Murakami 2001, 2012; Middleton & Brown 2005, 133-136).

Drawing on various resources and requirements (as expressed by Dewey, Wittgenstein, Sellars, and Brandom), this paper proposes an externalist view of conceptual mental episodes that does not equate them, even partially, with vehicles of any sort, whether the vehicles be located in the environment or in the head. The social and pragmatic nature of the use of concepts and conceptual content makes it unnecessary and indeed impossible to locate the entities that realize conceptual mental episodes in non-personal or subpersonal contentful (...) entities (vehicles). Persons, who engage in social practices of deontic scorekeeping (Brandom), and who are thus able to produce appropriate inferential behaviour, enact conceptual mental episodes and the basis of their supervenience.

While Wittgenstein wrote unconventionally and denied that he was advancing philosophical theses, most of his interpreters have attributed conventional philosophical theses to him. But the best recent interpretations have taken the form of his writing and his distinctive way of doing philosophy seriously. The 1980s have also seen the emergence of a body of work on Wittgenstein that makes extensive use of the unpublished Wittgenstein papers. This work on Wittgenstein's method and his way of writing are the main themes of (...) this literature review.Section 1 surveys Wittgenstein's conception of philosophical method and its reception. Section 2 is a review of recent work on rule-following and the methodological issues it raises. Section 3 concerns research on the WittgensteinNachlass and its implications for the interpretation of his philosophy. (shrink)

Mediante un examen crítico de los ensayos publicados en Ideas y Valores acerca de la filosofía de Ludwig Wittgenstein, el escrito busca establecer qué tan rica es nuestra asimilación del pensamiento de uno de los grandes filósofos de la historia, si tal trabajo muestra una evolución a lo largo del devenir de la revista y si el examen que hago aquí puede darnos algún indicio acerca de nuestro desarrollo filosófico. Finalmente, se hacen algunas breves consideraciones acerca de lo que significa (...) hacer filosofía desde la periferia y algunas posibles ventajas que eso tiene, así como señalar la necesidad de realizar una labor más colectiva.

In this essay, I offer a critical evaluation of Hilary Putnam's writings on epistemology and philosophy of science, in particular his engagement with interpretative problems in quantum mechanics. I trace the development of his thinking from the late 1960s when he adopted a strong causal-realist position on issues of meaning, reference, and truth, via the "internal realist" approach of his middle-period writings, to the various forms of pragmatist, naturalized, or "commonsense" epistemology proposed in his latest books. My contention is that (...) Putnam's retreat from a full-fledged realist outlook has been prompted in large part by his belief that it cannot possibly be reconciled with the implications of quantum mechanics for our understanding of processes and events in the subatomic domain. However, I suggest, this response should be seen as premature given the range of as-yet unresolved problems with quantum mechanics on the orthodox (Copenhagen) interpretation and also the existence of an alternative account - David Bohm's hidden-variables theory - which perfectly matches the established predictive-observational results while providing a credible realist ontology. I also examine Putnam's case for adopting a nonstandard (three-valued) "quantum logic" in relation to the thinking of other philosophers - Michael Dummett among them - who have espoused a more global or doctrinaire version of anti-realism. I conclude that Putnam's early (causal-realist) position is by no means untenable in light of the various arguments that he now takes as counting decisively against it. (shrink)

I examine what I shall call meta-philosophy: a philosophical examination into what philosophy is, can be, should be, something of what it has been, what the point (if any) of it is and what, if anything, it can contribute to our understanding of and the making sense of our lives, including our lives individually and together, and of the social order in which we live.

What do we learn about language from reading Wittgenstein'sPhilosophical Investigations? This question gains urgency from Wittgenstein's alleged animus against philosophical theorizing and his indirectness. Section 1 argues that Wittgenstein's goal is to prevent philosophical questioning about the foundations of language from the beginning. This conception of his aim is not in tension with Wittgenstein's use of the notion of community; community interpretations of his views betray a misguided commitment to the coherence of the idea that language might need grounding. Wittgenstein's (...) goal is not to enjoin us not to step outside of language-games, but to show that we have insufficiently clear grasp of the terms we try to use to express the limits of intelligibility. Section 2 suggests that appreciating Wittgenstein's moral concerning the relation between language and philosophizing about it involves allowing him to teach us how to read his book. What makes readingPhilosophical Investigations possible is openness to learning how not to forget our lives in language. (shrink)

An attempt is made to answer the question why wittgenstein might have found the analogy between speaking and playing games philosophically exciting. It is argued that on the face of it the two are strikingly disanalogous, But that on reflecting further one can find various features of games (9 are distinguished in all) which are also features of some speech episodes, And the awareness of which could be philosophically significant.

ABSTRACTWittgenstein’s remark that one cannot follow a rule only once has generated two puzzles: how can everyone accept it to be true? and why does Wittgenstein advance it? These two puzzles have tormented commentators for decades. In this paper I put forward a new interpretation and explain away the two puzzles. I shall show that Wittgenstein’s remark is plain truth and that his motivation behind making it is to dissolve the picture theory of meaning propounded in the Tractatus. This interpretation (...) also helps us to see that Wittgenstein’s other remark, that to follow a rule is a custom, is also a grammatical one. (shrink)

In this essay, I seek to demonstrate the interplay of philosophical voices – particularly, that of a platonist voice and a community-agreement-view voice – that drives Wittgenstein’s rule-following dialectic forward; and I argue that each voice succumbs to a particular form of dialectical oscillation that renders its response to the problem of rule-following philosophically inadequate. Finally, I suggest that, by seeing and taking stock of the dilemma in which these responses to the skeptical problem are caught, we can come to (...) appreciate Wittgenstein’s own view of what might constitute a proper a response to the so-called problem of rule-following. This view can be preliminarily characterized by saying that Wittgenstein’s aim is to dissolve the temptation to philosophically rebut the skeptical challenge posed by the rule-following dialectic, an aim he achieves by revealing the semantic emptiness of the apparent sentences that raise the skeptical problem.

The German physicist Heinrich Hertz played a decisive role for Wittgenstein's use of a unique philosophical method. Wittgenstein applied this method successfully to critical problems in logic and mathematics throughout his life. Logical paradoxes and foundational problems including those of mathematics were seen as pseudo-problems requiring clarity instead of solution. In effect, Wittgenstein's controversial response to David Hilbert and Kurt Gödel was deeply influenced by Hertz and can only be fully understood when seen in this context. To comprehend the arguments (...) against the metamathematical programme, and to appreciate how profoundly the philosophical method employed actually shaped the content of Wittgenstein's philosophy, it is necessary to make an intellectual biographical reconstruction of their philosophical framework, tracing the Hertzian elements in the early as well as in the later writings. In order to write Wittgenstein's biography, we have to take seriously the coherence of his thought throughout his life, and not let convenient philosophical ideologies be our guidance in drawing up a “Wittgensteinian philosophy”. To do so, we have to take a second look upon what he actually wrote, not only in the already published material, but in the entire Nachlass. Clearly, this is not easily done, but it is a necessary task in the historical reconstruction of Wittgenstein's life and work. (shrink)

This paper is concerned with the status of a symbol in Wittgenstein’s Tractatus. It is claimed in the first section that a Tractarian symbol, whilst essentially a syntactic entity to be distinguished from the mark or sound that is its sign, bears its semantic significance only inessentially. In the second and third sections I pursue this point of exegesis through the Tractarian discussions of nonsense and the context principle respectively. The final section of the paper places the forgoing work in (...) a secondary context, addressing in particular a debate regarding the realism of the Tractatus. (shrink)

The power of Wittgenstein's N operator described in the Tractatus is that every proposition which can be expressed in the Russellian variant of the predicate calculus familiar to him has an equivalent proposition in an extended variant of his N operator notation. This remains true if the bound variables are understood in the usual inclusive sense or in Wittgenstein's restrictive exclusive sense. The problematic limit of Wittgenstein's N operator comes from his claim that symbols alone reveal the logical status of (...) propositions. This would require knowledge of the size of the Tractarian domain of unchangeable, simple objects, and this, Wittgenstein maintained, cannot be known. (shrink)

Reason, objectivity, and human nature are now suspect ideas. Among postmodern thinkers, Richard Rorty has advanced an especially forceful critique of these notions. Drawing partly on Wittgenstein's philosophy of language, Rorty contends that objectivity is no more than a metaphysical name for intersubjective agreement, and that “human nature” is an empty category, there being nothing beneath history and culture. Wittgenstein himself, however, recognized within the world's many civilizations “the common behavior of mankind,” without which Rorty's ethnocentric “solidarity” would be inconceivable. (...) This common form of life—the life of those who speak—encompasses countless human activities that presuppose and are interwoven with the concepts of reason and objectivity. (shrink)

RESUMO O objetivo deste artigo é mostrar que as interpretações "tradicional" e "resoluta" não livraram o "Tractatus" da aparente autoderrota paradoxal. Argumento que essas leituras apresentam apenas uma nova roupagem ao paradoxo. A leitura "tradicional" de Hacker acaba atribuindo uma conspiração metafísica ao "Tractatus", o que é incompatível com os objetivos do livro. A leitura "resoluta" de Diamond e Conant atribui a Wittgenstein uma conspiração autoral, o que contradiz suas opiniões sobre autoria e método. Com base nas dificuldades encontradas em (...) ambos os lados do debate atual, concluo este artigo propondo vários requisitos que a correta interpretação do "Tractatus" deve preencher. (shrink)

This paper provides evidence for a radically enactive, embodied account of remembering. By looking closely at highly context-dependent instances of memorizing and recalling dance material, I aim at shedding light on the workings of memory. Challenging the view that cognition fundamentally entails contentful mental representation, the examples I discuss attest the existence of non-representational instances of memory, accommodating episodic memory. That being so, this paper also makes room for content-involving forms of remembering. As a result, it supports the duplex vision (...) of mentality advanced by the REC framework. Building on research on the enactive imagination, I suggest that contentless forms of remembering act below content-involving forms. In addition, contentless and contentful forms of remembering a movement are revealed as the product of culturally scaffolded engagements with others and the environment, in which direct perception and mirroring play a fundamental role. It is argued that many of the practices of remembering a movement are best explained as enactments or re-enactments of such direct ecological perceptions. In the process, the dance studio proves to be a paradigm of the extensive mind. This paper is also intended as an invitation to the REC framework to extend the family and explicitly embrace research on sociocultural practices as an equal partner, including dance studies. Given the fundamental role that sociocultural practices play in REC’s understanding of cognition, it is only natural that further radicalization goes along those lines. (shrink)

The reflections on music are crucial in the philosophy of language and the mind of the second Wittgenstein. These reflections go around the comparisons Wittgenstein did between meaning and understanding language, and meaning and understanding music. Musical passages show a language as independent from reality, i.e. objects, events or mental states, centered instead in intonations, conclusions, parenthesis, confirmations, questions and answers, a phenomenon enough studied in musicology. Two interpretations on the signification of musical meaning are analyzed: Ahonen’s formalist view [2005], (...) based in the following of rules, and Scruton’s expressive view [2004], based on the comparison between the intuitive recognition of a mental state “hidden” behind the facial expressions. As a conclusion we arrive to a mixed argument: Either of the alternatives whether annulling the other, are possibly telling about Wittgenstein’s conception but do not elucidate the problem itself.

In this paper I argue that the most prominent and familiar features of Wittgenstein’s rule following considerations generate a powerful argument for the thesis that most of our concepts are innate, an argument that echoes a Chomskyan poverty of the stimulus argument. This argument has a significance over and above what it tells us about Wittgenstein’s implicit commitments. For, it puts considerable pressure on widely held contemporary views of concept learning, such as the view that we learn concepts by constructing (...) prototypes. This should lead us to abandon our general default hostility to concept nativism and be much more sceptical of claims made on behalf of learning theories. (shrink)

Although the expression “form of life” and its plural “forms of life” occur only five times in Philosophical Investigations, and generally few times in his works, it is commonly agreed that this is one of the most relevant issues in Wittgenstein’s later philosophy. Starting from the analysis of the contexts in which Wittgenstein makes use of this concept, the paper focuses on the different interpretations that have been given in secondary literature, and proposes a classification based on two axes of (...) debate: the monistic versus pluralistic interpretation, and the empirical versus transcendental interpretation. After placing some well-known readings in the resulting scheme, an attempt will be made to offer an evolutionary reading of Wittgenstein’s own ideas about forms of life. It will be argued that the empirical and plural view that seems characteristic of his writings in the Thirties, slowly appears to turn towards a monistic view, sometimes with transcendental tones, although within a pragmatic perspective. This turn remains nevertheless rooted in Wittgenstein’s general attitude towards philosophy intended as a conceptual inquiry with clarifying and therapeutic aims. (shrink)

O presente manual tem como intenção constituir um guia para uma disciplina introdutória de filosofia da linguagem. Foi elaborado a partir da leccionação da disciplina de Filosofia da Linguagem I na Faculdade de Letras da Universidade do Porto desde 2001. A disciplina de Filosofia da Linguagem I ocupa um semestre lectivo e proporciona aos estudantes o primeiro contacto sistemático com a área da filosofia da linguagem. Pretende-se que este manual ofereça aos estudantes os instrumentos necessários não apenas para acompanhar uma (...) iniciação ao campo da filosofia da linguagem mas também para o estudo e a investigação autónomos posteriores. Para isso é percorrido um trajecto que conduz das intuições pré-teóricas acerca de linguagem, de que todos dispomos, até um conhecimento disciplinar específico, histórico e temático, da filosofia da linguagem. Em termos práticos, são considerados como precedentes da disciplina de Filosofia da Linguagem I – mesmo se, pelo existem actualmente precedências em sentido estrito – as disciplinas de Lógica I e II e de Filosofia do Conhecimento I e II. Os programas dessas disciplinas nos últimos anos estiveram presentes por trás da elaboração do manual. (shrink)

This volume consists of the invited papers presented at the 23rd International Wittgenstein Conference held in Kirchberg, Austria in August 2000. Among the topics treated are: truth, psychologism, science, the nature of rational discourse, practical reason, contextualism, vagueness, types of rationality, the rationality of religious belief, and Wittgenstein. Questions addressed include: Is rationality tied to special sorts of contexts? ls rationality tied to language? Is scientific rationality the only kind of rationality? Is there something like a Western rationality? and: Could (...) we genetically engineer human beings to be less wicked? (shrink)

SUMMARY Major theories of philosophical psychology and philosophy of mind are examined on the basis of the fundamental questions of ontology, metaphysics, epistemology, semantics and logic. The result is the choice between language of eliminative reductionism and dualism, neither of which answers properly the relation between mind and body. In the search for a non–dualistic and non–reductive language, Wittgenstein’s notion of language–games as the representative links between language and the world is considered together with Peirce’s semeiosis of cognition. The result (...) is a redefined notion of cognition as the goal–oriented ability to instantiate strategies from the rules of the language–games. Cognition is considered within the four-dimensional languagegames: rules/strategies, primitive/complete language-games, family-resemblances/forms of life, and non-temporal continuum as the language-games’ modality. Cognition is seen as a continuum process of non–individualized elements that unites perception, volition, emotion, will and thought against the commonly accepted understandings of cognition in exclusive terms of perception and thinking. The alternative to the mind/body problem is the continuity of cognition where rules and strategies, syntax and semantics, are considered inseparable within language–games. This continuity of cognition is explained in terms of virtual (univocal) identity, replacing the old philosophical paradigm of the mind/body problem. -/- SOMMARIO Le teorie maggiori della psicologia filosofica e filosofia della mente sono esaminate a partire dalle questioni fondamentali di ontologia, metafisica, epistemologia, semantica e logica. Il risultato è la scelta tra un linguaggio riduzionista eliminativo e un dualismo che però non confronta in modo adeguato la relazione tra mente e corpo. Nella ricerca per un linguaggio non-dualistico e non-riduttivo, viene considerata la nozione del gioco linguistico di Wittgenstein come un legame rappresentativo tra il linguaggio e il mondo insieme con la semiosi cognitiva di Peirce. Il risultato è la nozione ridefinita della cognizione come abilità goal-orientata di creare le strategie dalle regole dei giochi linguistici. La cognizione è considerata entro le quattro dimensioni dei giochi linguistici: regole/strategie, giochi linguistici primitivi/completi, somiglianze di famiglia/forme di vita, e la continuità atemporale come la modalità dei giochi linguistici. La cognizione diventa un processo continuo degli elementi non-individualizzati che tende ad unificare la percezione, volizione, emozione, la volontà e il pensiero contro un concetto generalmente accettato di vedere la cognizione nei termini esclusivamente di percezione e di pensiero. L’alternativa al problema della mente/corpo è la continuità della cognizione, dove le regole e le strategie, la sintassi e la semantica, sono considerate inseparabili nei giochi linguistici. Questa continuità della cognizione è spiegata nei termini dell’identità virtuale (univoca) sostituendo un paradigma filosofico previo del problema della mente/corpo. (shrink)

Many contributors of the debate about knowledge by testimony concentrate on the problem of justification. In my paper I will stress a different point – the concept of testimony itself. As a starting point I will use the definitional proposal of Jennifer Lackey. She holds that the concept of testimony should be regarded as entailing two aspects – one corresponding to the speaker, the other one to the hearer. I will adopt the assumption that we need to deal with both (...) aspects. Nevertheless, I will show that her concept – which suggests regarding testimony as an act of communication conveying information – is too broad and, therefore, I will end up with a different twofold definition.

In this paper I have two objectives. First, I attempt to call attention to the incoherence of the widely accepted anti-essentialist interpretation of Wittgenstein’s family resemblance point. Second, I claim that the family resemblance idea is not meant to reject essentialism, but to render this doctrine irrelevant, by dissipating its philosophical force. I argue that the role of the family resemblance point in later Wittgenstein’s views can be better understood in light of the provocative aim of his philosophical method, as (...) stated (for instance) in PI 133: “[t]he philosophical problems” - associated with essentialism in this case, "should completely disappear".

So selbstverständlich es klingt, vom Geist, der Psyche oder auch der Seele eines Menschen zu reden, und so vertraut uns wissenschaftliche Disziplinen sind, die sich philosophisch oder empirisch damit beschäftigen, so schwer fällt es, ein einheitliches Merkmale dafür anzugeben, wann etwas ein psychisches Phänomen ist. Viele der potentiellen Merkmale decken eben nur einen Teil des Spektrums dessen ab, was wir gewöhnlich als psychisch bezeichnen würden, und sind damit bestenfalls hinreichende, aber sicher keine notwendigen Bedingungen des Psychischen. Im Mittelpunkt des folgenden (...) Artikels wird dagegen ein Merkmal stehen, von dem feststeht, daß es nicht hinreichend ist, von dem man aber vermuten kann, es sei zumindest notwendig: die Individualität psychischer Phänomene. Die Frage, mit der ich mich beschäftigen werde, ist, ob sich diese Vermutung mit Bezug auf eine Grnppe paradigmatisch psychischer Phänomene aufrecht erhalten läßt, die intentionalen Einstellungen.
