De um modo geral, queríamos mostrar que a filosofia tem suas próprias áreas, mas tem também subáreas em interdisciplinaridade com as ciências. As ciências e as disciplinas acadêmicas em geral têm problemas, cuja a solução pode ser encontrada empiricamente, por meio de experimentos, entrevistas, documentos, ou formalmente, por meio de cálculos etc, porém os problemas das filosofias dessas disciplinas são justamente os problemas mais fundamentais dessas disciplinas, que fundam o quadro conceitual e de pesquisa das mesmas, e que só poderiam (...) ser respondidos por meio de uma extensa argumentação. A filosofia de cada uma dessas disciplinas é uma mistura (a) de metafísica da disciplina, perguntando-se qual a natureza e justificação das entidades que formam o quadro teórico da disciplina, i.e., quais delas realmente existem na realidade (não sendo meros instrumentos para obter resultados) e quais as suas categorizações fundamentais, naturezas e funções teóricas, (b) de epistemologia dessa disciplina, ao nos perguntarmos sobre como tal área poderia obter conhecimento de modo confiável e se ela de fato o faz, e (c) de teorias do valor, ao nos perguntarmos, por exemplo, sobre qual o valor moral do desenvolvimento de uma certa disciplina e, finalmente, (d) a lógica, que perpassa tudo, ao nos perguntarmos sobre a consistência das teses assumidas pela disciplina. Não é à toa que falamos que a filosofia é mãe de todas as ciências. Ela é mãe tanto num sentido geracional, pois a maioria das ciências foram desenvolvimentos particulares, empíricos ou de cálculo, das questões filosóficas sobre um certo tema, quanto num sentido fundamental, pois é a filosofia que fornece os fundamentos mais gerais, metafísicos, epistêmicos, valorativos e lógicos, na construção do quadro teórico de cada ciência e na qualidade dos métodos para se aproximar da verdade que a disciplina utiliza. A biologia, por exemplo, foi criada por Aristóteles, tal como os primeiros desenvolvimentos da meteorologia (na verdade, esta começa com os pré-socráticos), e grande parte do fundamento da física atual jaz nas discussões de filosofia da física. Sendo você filósofo ou cientista de outra área, a filosofia promete te dar as bases para uma reflexão geral ou sobre sua área, que seja muito mais informada e profunda do que aquilo que você poderia realizar sem ela. /// In general, we wanted to show that philosophy has its own areas, but it also has subareas in interdisciplinarity with the sciences. The sciences and academic disciplines in general have problems, the solution of which can be found empirically, through experiments, interviews, documents, or formally, through calculations etc., but the problems of the philosophies of these disciplines are precisely the most fundamental problems. of these disciplines, which build their conceptual and research framework, and which could only be answered through extensive argumentation. The philosophy of each of these disciplines is a mixture (a) of metaphysics of the discipline, asking what is the nature and justification of the entities that form the theoretical framework of the discipline, ie, which ones really exist in reality (not being mere instruments for achieving results) and what are its fundamental categorizations, natures and theoretical functions, (b) the epistemology of this discipline, when we ask ourselves how such an area could obtain knowledge reliably and if it does, and (c) theories of value, when we ask ourselves, for example, about the moral value of the development of a certain discipline and, finally, (d) the logic, which permeates everything, when we ask ourselves about the consistency of the theses assumed by the discipline. It is not for nothing that we say that philosophy is the mother of all sciences. It is a mother both in a generational sense, as most sciences were particular empirical or formal developments of philosophical questions on a certain topic, and in a fundamental sense, as it is philosophy that provides the most general, metaphysical, epistemic, evaluative and logical foundations, in the construction of the theoretical framework of each science and in the quality of the methods to approach the truth that the discipline uses. Biology, for example, was created by Aristotle, like the first developments in meteorology (in fact, it starts with the pre-Socratics), and much of the foundation of current physics lies in discussions of the philosophy of physics. Whether you are a philosopher or scientist from another area, philosophy promises to give you the basis for a general reflection or about your area, which is much more informed and profound than what you could accomplish without it.

Uma das características mais interessantes da filosofia é sua capacidade de revelar problemas difíceis em lugares inesperados. É precisamente isto que ocorre com o caso dos nomes próprios. Usamos nomes cotidianamente para selecionar ou fazer referência a objetos particulares, e depois podermos dizer algo sobre eles. Talvez o leitor diga a um colega que gostaria de estar tomando um café em Paris, ao invés de gastar tempo lendo mais um livro de filosofia. Neste caso, estará usando o nome “Paris” para (...) se referir a um lugar específico do universo. O que você acaba de fazer não é meramente proferir um som, mas proferir um som que de alguma forma lhe permite selecionar uma localidade específica dentre todas as outras do universo. É desta localidade que você fala. Mas como isto é possível? Que tipo de mecanismo garante a alguém o poder de proferir um nome e, com isto, selecionar um particular específico dentre todos os outros do universo? Este é o problema da referência singular dos nomes próprios. O presente livro é sobre este problema. -/- . (shrink)

When you think about a particular object, what makes your thought about that object? Roderick Chisholm, Ernest Sosa and Michael McKinsey have defended 'latitudinarian', 'descriptivist', or what I call 'liberal' answers to that question. In this paper I carefully consider the motivation for these liberal views and show how it extends in unanticipated ways to motivate views that are considerably more liberal.

We think about and refer to things that we’ve never perceived or experienced. This paper bears on how this could be. Someone is testimonially acquainted with something just in case the explanation of one’s ability to think de re thoughts about it essentially appeals to communication with others who already have that ability. The main motivation for the claim that testimonial acquaintance is possible is that it best explains how we can think de re about and refer to things we’ve (...) never perceived or experienced: we gain these abilities in part by communicating with those who already have them. The main point of this paper is negative: to argue that testimonial acquaintance, as we currently understand it, is impossible. Although one might take this to show that we cannot be acquainted with things we haven’t perceived or experienced, I prefer to think of it as motivation for rethinking the nature of acquaintance.

The most popular and influential strategies used against semantic externalism and the causal theory of reference are critically examined. It is argued that upon closer scrutiny, none of them emerges as truly convincing.

In his (1978) and parts of (1993), Philip Kitcher advances a new context-sensitive theory of reference which he applies to abandoned theoretical expression-types, such as Joseph Priestley’s ‘dephlogisticated air’, in order to show that, although qua types they fail to refer uniformly, they nonetheless have referential tokens. This piece offers a critical examination of Kitcher’s theory. After a general investigation into the overall adequacy of Kitcher’s theory as a general account of reference, I focus on the case of abandoned theoretical (...) terms. Kitcher’s theory is meant to be able to evaluate and solve disputes about referential continuity and progress in scientific theorychange. To this end, Kitcher employs the principle of humanity and a notion of the “correct historical explanation” of the production of each expression-token. I argue that the application of the principle of humanity does not offer a principled way to show that the historical actors were involved in different modes of reference when they produced different tokens of an expressiontype. I also suggest that the principle of humanity, coupled with Kitcher’s view that tokens of expression-types may systematically refer to different things, makes conceptual progress too easy and thus uninteresting.

It is commonly held that our intuitive judgements about imaginary problem cases are justified a priori, if and when they are justified at all. In this paper I defend this view — ‘rationalism’ — against a recent objection by Timothy Williamson. I argue that his objection fails on multiple grounds, but the reasons why it fails are instructive. Williamson argues from a claim about the semantics of intuitive judgements, to a claim about their psychological underpinnings, to the denial of rationalism. (...) I argue that the psychological claim — that a capacity for mental simulation explains our intuitive judgements — does not, even if true, provide reasons to reject rationalism. (More generally, a simulation hypothesis, about any category of judgements, is very limited in its epistemological implications: it is pitched at a level of explanation that is insensitive to central epistemic distinctions.) I also argue that Williamson’s semantic claim — that intuitive judgements are judgements of counterfactuals — is mistaken; rather, I propose, they are a certain kind of metaphysical possibility judgement. Several other competing proposals are also examined and criticized. (shrink)

The “scientific essentialist” doctrine asserts that the following are examples of a posteriori necessary identities: water is H2O; gold is the element with atomic number 79; and heat is the motion of molecules. Evidence in support of this assertion, however, is difficult to find. Both Hilary Putnam and Saul Kripke have argued convincingly for the existence of a posteriori necessities. Furthermore, Kripke has argued for the existence of a posteriori necessary identities in regard to a particular class of statements involving (...) proper names. Neither Kripke nor Putnam, however, has argued convincingly that sentences containing syntactically complex terms or descriptive phrases can express a posteriori necessary identities. I will argue by way of a hypothetical example that ‘water is H2O’ does not express a necessary identity. My argument is unique in that it attacks the relevant sufficiency claim needed to underwrite this putative necessary identity.1 That is, even if we grant that water is necessarily composed of H2O, we should not accept that H2O necessarily forms water.

The phrase "natural kind term" has come into the linguistic and philosophical literature in connection with well-known work of Kripke (1972) and Putnam (1970, 1975a). I use that phrase here in the sense it has acquired from those and subseqnent works on related topics. This is not the transparent sense of the phrase. That is, if I am right in what follows there are words for kinds of things existing in nature which are not natural kind terms in the current (...) sense - e.g. planet, woman, and weed. I use the term "nondescriptional", following Salmon (1981), to mean "lacking a Fregean sense", where a Fregean sense is taken to be a property or group of properties semantically associated with an expression which determines its denotation. I hope that the term "nondescriptional" will be clarified in subsequent discussion, but perhaps a few words about it and its opposite, "descriptional", would be useful here. These terms (as Salmon notes (p.15, n. 11)) should be taken as technical terms. The idea is that descriptional words, of which bachelor is the overwhelmingly favorite example, express a semantic content, or sense, which is what mediates their denotation. Entities fall in their denotation in virtue of possessing the property or properties expressed as their sense. (It is not necessary, however, that this sense be as easily paraphrasable with descriptive synonyms as it is typically held to be in the case of bachelor, or even that it be paraphrasable at all.) In the case of nondescriptional words there is no Fregean sense to mediate the link between word and object. Hence such terms are described by what Salmon, following Kaplan, calls "the theory of direct reference". What it is that does associate such terms with their denotations is another question which will be touched on briefly at the end. I have several aims in this paper. The first is to defend a conservative position on nondescriptionality. I will argue that relatively few natural language words have this property. My other aims are primarily clarificatory. Among the issues I would like to clarify are those connected with the determination of this property and flae explanation of why it exists, its relationship with other properties such as rigid designation and essentiality, and its significance for lexical semantics. The organization of the paper is as follows. The first section identifies the position taken here on the question of which expressions are nondescriptional and provides a general defense of it. The second section is a critical examination of criteria associated with nondescriptionality. In the third section provide further defense for the conservative position, and in the fourth section we turn to related issues in lexical semantics. (shrink)

The new theory of reference has won popularity. However, a number of noted philosophers have also attempted to reply to the critical arguments of Kripke and others, and aimed to vindicate the description theory of reference. Such responses are often based on ingenious novel kinds of descriptions, such as rigidified descriptions, causal descriptions, and metalinguistic descriptions. This prolonged debate raises the doubt whether different parties really have any shared understanding of what the central question of the philosophical theory of reference (...) is: what is the main question to which descriptivism and the causal-historical theory have presented competing answers. One aim of the paper is to clarify this issue. The most influential objections to the new theory of reference are critically reviewed. Special attention is also paid to certain important later advances in the new theory of reference, due to Devitt and others. (shrink)

Suosituimpia ja vaikutusvaltaisimpia semanttista eksternalismia ja kausaalista viittaamisen teoriaa vastaan käytettyjä strategioita arvioidaan kriittisesti. Tarkemmassa tarkastelussa mikään niistä ei osoittaudu erityisen vakuuttavaksi.

According to a doctrine that has been popularized by Kripke and Putnam, a natural kind term like 'bird' rigidly designates the kind with the microstructure of sample birds. This microstructure is the essence of birdhood, so our learning what the relevant microstructure is our discovery of the kind's essence. We have discovered that some statement like 'The bird is the taxon with such and such DNA structure' is true. Further, it is commonly added, the discovered microstructure is essential to each (...) particular bird. ;I argue that this general picture is mistaken. I do accept and defend the view that terms like 'bird' are rigid designators. However, the picture at issue has other difficulties. Individual birds are not essentially birds. And the view that biologists have discovered or will discover that the bird kind is identical to some DNA structure or other type of structure seems wrong. We don't discover just what particular characteristic a kind is to be identified with. Rather, the meaning of natural kind terms changes; as science advances, more sophisticated concepts attending kind terms replace older ones. So the Kripke-Putnam account of our discovering the truth of theoretical identity statements seems wrong. ;Fortunately, the account retains some interest despite its falsity, because of its association with the claim that statements like 'The bird is the taxon with such and such DNA structure' are necessary but a posteriori. The above sentence does not express a truth, much less a necessary truth, but the idea that it could have expressed the sort of necessary a posteriori truth it is supposed to express is epistemologically interesting. The very possibility of such necessary a posteriori knowledge deserves some account. I offer an account, arguing that this sort of knowledge is no more impressive from an epistemological standpoint than is knowledge of analytic necessity: indeed, I argue, it is best understood as knowledge of a species of analytic necessity. Independently of this claim, I argue in a concluding discussion that analyticity ought to be accepted by proponents of the necessary theoretical identity statements in question. (shrink)
