Há alguns anos atrás, algumas pessoas acreditavam que a tese de que a existência não é um predicado, uma tese defendida por autoridades como Gottlob Frege e Bertrand Russell, era um dos traços distintivos da chamada filosofia analítica. Que uma tal crença é afinal falsa pode ser tomado como mais um sinal da vitalidade e do anti-dogmatismo que caracterizam em geral a tradição analítica; e o mesmo se aplica a quaisquer outras crenças do género, que comprometam esta tradição com teses (...) filosóficas substantivas. O meu propósito neste ensaio é duplo. Por um lado, descrevo o estado actual da questão relativamente ao venerável tópico da existência, caracterizando e examinando as principais teorias disponíveis. Por outro, argumento a favor de um ponto de vista específico sobre o tópico. Esse ponto de vista consiste na conjunção das seguintes três teses: (F) Não há objectos não-existentes; (H*) A existência é um predicado; e (H**) As afirmações de existência não são uniformes quanto à forma lógica, tendo por vezes a forma de quantificações existenciais e por vezes a forma de predicações monádicas de primeira ordem.

People often speak loosely, uttering sentences that are plainly false on their most strict interpretation. In understanding such speakers, we face a problem of underdetermination: there is often no unique interpretation that captures what they meant. Focusing on the case of incomplete definite descriptions, this paper suggests that speakers often mean bundles of propositions. When a speaker means a bundle, their audience can know what they mean by deriving any one of its members. Rather than posing a problem for the (...) interpretation of loose talk, the underdetermination of a uniquely correct interpretation allows for various ways in which the audience can grasp the speaker’s meaning.

Jin Yuelin’s logical and philosophical thought was deeply influenced by the philosophy of Bertrand Russell. The same influence existed also in the case of his view on truth, which was considerably close to the views maintained by Russell in his phase of logical atomism. In their investigations, Russell and Jin not only focused on similar topics, but also occupied similar philosophical positions, such as realism in the domain of ontology, empiricism in epistemology, and the correspondence theory in the domain of (...) the theory of truth. Nevertheless, Jin Yuelin’s view on truth was not only a mere imitation or recapitulation or even plagiarized copy of Russell’s, but also contained innovations and characteristics of its own. Jin, for example, emphasized certain general characteristics of truth, including the notion of truth as a relational quality, that truth is not a matter of degree, and that it is relative neither to time and space nor to the different types of knowledge. By so doing, Jin underlined the objectiveness, reliability, and transcendence of true propositions. By arguing that the correspondence theory of truth possessed strong foundations in common sense, Jin set out to defend the role of common sense in philosophy and science, maintaining that the former cannot be completely eliminated and arguing against the notion that any modification of a part of common sense would ultimately be founded on yet another segment of common sense. Moreover, Jin delivered his own response against the theory of the gap between “subject and object/the internal and the external,” which had been used to question the correspondence theory of truth, proposing a variety of cognitivist theory, which defined facts as “the given” (datum) that has been received and arranged. Most importantly, facts are cognitive constructs created on the basis of “the given” and encapsulate both subjectiveness and objectiveness. Jin Yuelin was a modern Chinese philosopher who had achieved profound erudition in both Chinese and Western thought, and, above all, an independent an profoundly original thinker. (shrink)

This paper aims to solve the following twofold problem. Suppose that a rational speaker, Ralph, mistakenly takes (for some reason) the Roman orator Cicero and the World War II German spy Cicero to be the same individual. By sincerely uttering the sentence “Cicero is an orator and a spy”, (a) does Ralph use the name “Cicero” of the Roman orator or the name “Cicero” of the German spy or another name of the genus “Cicero”? And (b) which Cicero does Ralph (...) refer to: the Roman orator, the German spy, both of them or neither of them? After drawing a distinction between the notion of mistaking one individual for another (exemplified by Kripke's “Jones”/“Smith” case and Putnam's “water”/“water” case) and the notion of wrongly taking two individuals to be one and the same individual (exemplified by the “Cicero”/“Cicero” case under discussion), I will defend the following solution to the last puzzling case: Ralph inadvertently creates an abstract individual playing the role of “fusion” or “amalgam” of the two Ciceros and also inadvertently creates a new name “Cicero” referring to such an individual.

This paper enters the continuing fray over the semantic significance of Donnellan’s referential/attributive distinction. Some holdthat the distinction is at bottom a pragmatic one: i.e., that the difference between the referential use and the attributive use arises at the level of speaker’s meaning rather the level of sentence-or utterance-meaning. This view has recently been challenged byMarga Reimer andMichael Devitt, both of whom argue that the fact that descriptions are regularly, that is standardly, usedto refer defeats the pragmatic approach. The present (...) paper examines a variety of issues bearing on the regularity in question: whether the regularity would arise in a Russellian language, whether the regularity is similar to the standard use ofcomplex demonstratives, and whether the pragmatic approach founders on the problem of dead metaphors. I argue that the pragmatic approach can readily explain all of these facets ofthe referential use of descriptions. (shrink)

Two subject-predicate calculi with equality,SP = and its extensionUSP =, are presented as systems of natural deduction. Both the calculi are systems of free logic. Their presentation is preceded by an intuitive motivation.It is shown that Aristotle's syllogistics without the laws of identitySaP andSiP is definable withinSP =, and that the first-order predicate logic is definable withinUSP =.

The author contends that the Objectivist epistemology has lacked a viable model of propositional knowledge for nearly fifty years, due to neglect of Rand's unit-perspective view of concepts. This pioneering insight, he says, not only is an essential building block of her concept theory, but also welds together the three levels of logical theory and provides the clearest X-ray picture of our multilayered conceptual knowledge. Using the unit-perspective to expand Rand's theory of concepts, the author then devises a theory of (...) the proposition, giving considerable attention to axioms and statements about nonexistent subjects.

Attempting to compare scientific theories requires a philosophical model of meaning. Yet different scientific theories have at times—particularly in early chemistry—pre-supposed disparate theories of meaning. When two theories of meaning are incommensurable, we must say that the scientific theories that rely upon them are meta-incommensurable. Meta- incommensurability is a more profound sceptical threat to science since, unlike first-order incommensurability, it implies complete incomparability.

In 'Fiction and Fictionalism', Mark Sainsbury has recently dubbed “Selection Problem” a serious trouble for Meinongian object theories. Typically, Meinongianism has been phrased as a kind of realism on nonexistent objects : these are mind-independent things, not mental simulacra, having the properties they have independently from the activity of any cognitive agent. But how can one single out an object we have no causal acquaintance with, and which is devoid of spatiotemporal location, picking it out from a pre-determined, mind-independent set (...) ? In this paper, I set out a line of response by distinguishing different ways in which a thing may not exist. I show that the selection problem (a) does not arise for past, currently nonexistent objects ; (b) may not arise also for future existents (provided one massages naïve intuitions a bit) ; and (c) even for mere possibilia ; but (d) is a real snag for purely fictional objects, such as Holmes or Gandalf. As for (d), I propose a solution that forces Meinongianism to introduce a kind of ontological dependence of purely fictional nonexistents upon existents. The strategy complicates the intuitively simple, naïve Meinongian framework a bit, but looks quite promising. (shrink)

In Direct Belief I argue for the Theory of Direct Belief, which treats having a belief about an individual as an unmediated relation between the believer and the individual the belief is about. After a critical review of alternative positions, I use Grice’s theory of conversational implicature to provide a detailed pragmatic account of substitution failure in belief ascriptions and go on to defend this view against objections, including those based on an unwarranted “Inner Speech” Picture of Thought. The work (...) serves as a case study in pragmatic explanation, dealing also with methodological issues about context-sensitivity in language and the relation between semantics and pragmatics.

Russell takes his paper ?On denoting? to have achieved the repudiation of the theory of denoting concepts and Frege?s theory of sense, and the invention of the notion of incomplete symbols.This means that Russell attempts to solve the set theoretic and semantic paradoxes without making use of a theory of sense.Instead, his strategy is to revise his logical ontology by arguing that certain symbols should be treated as incomplete.In constructing such arguments Russell, at various points, makes use of epistemological and (...) metaphysical considerations.These arguments do not form themselves into a systemic set of considerations to be used in appraising a logical system.Finally, the vicious circle principle is argued for on the basis of considerations, which are presumed evident, about the nature of propositional functions.The stringency of this principle is a basic problem for the system of Principia mathematica.However, even given the terms of the argument, ?On denoting? does not offer a complete repudiation of the notion of sense.This allows the possibility of retaining some of the insights of Principia mathematica whilst rejecting the stringency of the vicious circle principle.The basis of such a system is the theory of sense.

Noneism a is form of Meinongianism, proposed by Richard Routley and developed and improved by Graham Priest in his widely discussed book Towards Non-Being. Priest's noneism is based upon the double move of building a worlds semantics including impossible worlds, besides possible ones, and admitting a new comprehension principle for objects, differerent from the ones proposed in other kinds of neo-Meinongian theories, such as Parsons' and Zalta's. The new principle has no restrictions on the sets of properties that can deliver (...) objects, but parameterizes the having of properties by objects to worlds. Modality is therefore explicitly built in - so the approach can be conveniently labeled as "modal noneism". In this paper, I put modal noneism to work by testing it against classical issues in modal logic and semantics. It turns out that - perhaps surprisingly - the theory performs well in problems of transworld identity, which are frequently considered to be the difficult ones in the literature; faces a limitation, albeit not a severe one, when one comes to transworld individuation, which is often taken as an easy issue, if not a pseudo-problem; and may stumble upon a real trouble when dealing with what I shall call 'extensionally indiscernible entities' - particular nonexistent objects modal noneism is committed to.

We outline a neo-Meinongian framework labeled as Modal Meinongian Metaphysics (MMM) to account for the ontology and semantics of fictional discourse. Several competing accounts of fictional objects are originated by the fact that our talking of them mirrors incoherent intuitions: mainstream theories of fiction privilege some such intuitions, but are forced to account for others via complicated paraphrases of the relevant sentences. An ideal theory should resort to as few paraphrases as possible. In Sect. 1, we make this explicit via (...) two methodological principles, called the Minimal Revision and the Acceptability Constraint. In Sect. 2, we introduce the standard distinction between internal and external fictional discourse. In Sects. 3–5, we discuss the approaches of (traditional) Meinongianism, Fictionalism, and Realism—and their main troubles. In Sect. 6 we propose our MMM approach. This is based upon (1) a modal semantics including impossible worlds (Subsect. 6.1); (2) a qualified Comprehension Principle for objects (Subsect. 6.2); (3) a notion of existence-entailment for properties (Subsect. 6.3). In Sect. 7 we present a formal semantics for MMM based upon a representation operator. And in Sect. 8 we have a look at how MMM solves the problems of the three aforementioned theories. (shrink)

Drawing on different suggestions from the literature, we outline a unified metaphysical framework, labeled as Modal Meinongian Metaphysics (MMM), combining Meinongian themes with a non-standard modal ontology. The MMM approach is based on (1) a comprehension principle (CP) for objects in unrestricted, but qualified form, and (2) the employment of an ontology of impossible worlds, besides possible ones. In §§1–2, we introduce the classical Meinongian metaphysics and consider two famous Russellian criticisms, namely (a) the charge of inconsistency and (b) the (...) claim that naïve Meinongianism allows one to prove that anything exists. In §3, we have impossible worlds enter the stage and provide independent justification for their use. In §4, we introduce our revised comprehension principle: our CP has no restriction on the (sets of) properties that can characterize objects, but parameterizes them to worlds, therefore having modality explicitly built into it. In §5, we propose an application of the MMM apparatus to fictional objects and defend the naturalness of our treatment against alternative approaches. Finally, in §6, we consider David Lewis’ notorious objection to impossibilia, and provide a reply to it by resorting to an ersatz account of worlds. (shrink)

Can the abstract entities be designated? While the empiricists usually took the positive answer to this question as the first step toward Platonism, in his ``Empiricism, Semantics, and Ontology’’ [Carnap 1950], Carnap tried to make a reconciliation between the language referring to abstract entities on the one hand, and empiricism on the other. In this paper, firstly, I show that the ingenuity of Carnap’s approach notwithstanding, it is prone to criticism from different aspects. But I also show how, even without (...) leaving the empiricist research program, the shortcomings could be amended. Following Carnap’s 1950 outset, and adding some apparently untasteful (Meinongian) ingredients, I will sketch a refined way for dealing with the problem of existence of abstract entities within the framework of the philosophy of empiricism.

The problem of the unity of the proposition—what distinguishes a proposition from a mere list of constituents, so that the former is able to say something while the latter is not?—is as old as philosophy. It is evoked at the end of Plato’s Sophist, where the Stranger affirms that when one makes a statement “he does not merely give names, but he reaches a conclusion by combining verbs with nouns” ; and it is discussed by Aristotle in De Interpretatione, where (...) it is said that since “falsity and truth have to do with combination and separation”, then “the first single statementmaking sentence is the affirmation, next is the negation” ; but “every statement-making..

In the earliest phase of his logical investigations, Peirce adopts Mill's doctrine of real Kinds as discussed in the System of Logic and adapts it to the logical conceptions he was then developing. In Peirce's definition of natural class, a crucial role is played by the notion of information: a natural class is a class of which some non-analytical proposition is true. In Peirce's hands, Mill's distinction between connotative and non-connotative terms becomes a distinction between symbolic and informative and pseudo-symbolic (...) and non-informative forms of representation. A symbol is for Peirce a representation which has information. Just as for Mill all names of Kind connote their being such, so for Peirce all symbols profess to correspond to a natural class.

Peirce seems to maintain two incompatible theses: that a sentence is multiply analyzable into subject and predicate, and that a sentence is uniquely analyzable as a combination of rhemata of first intention and rhemata of second intention. In this paper it is argued that the incompatibility disappears as soon as we distinguish, following Dummett’s work on Frege, two distinct notions of analysis: ‘analysis’ proper, whose purpose is to display the manner in which the sense of a sentence is determined by (...) the senses of its constituent parts, and ‘decomposition’, which is the process of dividing a sentence into a predicate and a subject, and whose purpose is to both to explain how quantified sentences are constructed and to evidence a pattern within a sentence which it shares with other sentences.

It is often claimed that scientists can obtain new knowledge about nature by running computer simulations. How is this possible? I answer this question by arguing that computer simulations are arguments. This view parallels Norton’s argument view about thought experiments. I show that computer simulations can be reconstructed as arguments that fully capture the epistemic power of the simulations. Assuming the extended mind hypothesis, I furthermore argue that running the computer simulation is to execute the reconstructing argument. I discuss some (...) objections and reject the view that computer simulations produce knowledge because they are experiments. I conclude by comparing thought experiments and computer simulations, assuming that both are arguments. (shrink)

In this paper it is shown how a partial semantics for presuppositions can be given which is empirically more satisfactory than its predecessors, and how this semantics can be integrated with a technically sound, compositional grammar in the Montagovian fashion. Additionally, it is argued that the classical objection to partial accounts of presupposition projection, namely that they lack “flexibility,” is based on a misconception. Partial logics can give rise to flexible predictions without postulating any ad hoc ambiguities. Finally, it is (...) shown how the partial foundation can be combined with a dynamic system of common-ground maintenance to account for accommodation. (shrink)

According to the standard opinions in the literature, blocking the unacceptable consequences of the notorious slingshot argument requires imposing constraints on the metaphysics of facts or on theories of definite descriptions (or class abstracts). This paper argues that both of these well-known strategies to rebut the slingshot overshoot the mark. The slingshot, first and foremost, raises the question as to the adequate logical formalization of statements about facts, i.e. of factual contexts. It will be shown that a rigorous application of (...) Quine’s maxim of shallow analysis to formalizations of factual contexts paves the way for an account of formalizing such contexts which blocks the slingshot without ramifications for theories of facts or definite descriptions.

This paper argues that proper names may have literal non-referential truth-conditional values, thereby undermining the notion of semantic reference.

A widely accepted thesis in the philosophy of language is that natural language proper names are rigid designators, and that they are so de jure, or as a matter of the “semantic rules of the language.” This paper questions this claim, arguing that rigidity cannot be plausibly construed as a property of name types and that the alternative, rigidity construed as a property of tokens, means that they cannot be considered rigid de jure; rigidity in this case must be viewed (...) as a pragmatic and not a semantic property.

This paper provides an interpretation and evaluation of Spinoza's highly original version of the ontological proof in terms of the concept of substance instead of the concept of perfection in the first book of his Ethics. Taking the lead from Kant'€™s critique of ontological arguments in the Critique of Pure Reason, the paper explores the underlying ontological and epistemological presuppositions of Spinoza'€™s proof. The main topics of consideration are the nature of Spinoza's definitions, the way he conceives of the relation (...) between a substance and its essence, and his conception of existence. Once clarity is shed upon these fundamental issues, it becomes possible to address the proof in its own terms. It is then easy to see that Kant's objections miss their target and that the same is true of those advanced by another of the ontological argument'€™s most famous critics, Bertrand Russell. Finally, several interpretations of Spinoza'€™s proof are proposed and critically evaluated; on all of them, the argument turns out to be either invalid or question-begging. (shrink)

In this paper, we present some experimental findings whose best explanation, first of all, provides a positive answer to a philosophical question in ontology as to whether, in the overall domain of beings, there are fictional characters (_ficta_) over and above concrete individuals. Moreover, since such findings arise out of different comparisons between fictional characters and concrete individuals on the one hand and fictional characters again and non-items that do not belong at all to such an overall domain on the (...) other hand, they also suggest that _ficta_ are allowed as inhabiting a particular subrealm of that domain distinct from the one inhabited by concrete individuals, as previous findings in cognitive psychology had suggested.

In this paper I defend the “Standard View” of the semantics of ‘I’—according to which ‘I’ is a pure, automatic indexical—from a challenge posed by “deferred reference” cases, in which occurrences of ‘I’ are (allegedly) not speaker-referential, and thus non-automatic. In reply, I offer an alternative account of the cases in question, which I call the “Description Analysis” (DA). According to DA, seemingly deferred-referential occurrences of the first person pronoun are interpreted as constituents of a definite description, whose operator scopes (...) over an open sentence Rxy—where R is a contextually selected relation ranging over pairs of people and objects. The role of intentions is thus limited to the determination of R, which is posterior to the fixation of the reference of ‘I’. In support of the DA I present evidence that, in the cases in question, the (Determiner) phrase containing ‘I’ behaves in relevant ways like a description. I show that the DA can account for the problematic examples, while preserving the simplicity of the standard semantics of ‘I’. Finally, I examine a rival account of the data, offered by Nunberg (Linguist Philos 16:1–43, 1993), and argue for the superiority of the DA. (shrink)

Departing from the dominant theories of Frege, Russell and Mill, Kit Fine has sketched a novel solution to Frege’s puzzle in his book Semantic Relationism. In this article, I briefly discuss the puzzle in its various forms and the attempted solutions of Frege and Russell. I then explicate the essential features of the new theory and critically appraise the mechanism suggested by Fine to solve the puzzle. I show that Semantic Relationism fails to address the concerns raised in the puzzle.

Quine’s philosophy comprises a bewildering set of views whose integrating principle is his "confirmed extensionalism". The paper offers a historical as well as an intellectual reconstruction of extensionalism. Traditional extensionalism (Boole) freed logic from Aristotelian essentialism that had inhibited the development of logic. Quine’s confirmed extensionalism is the acceptance, as a matter of course, of the validity of Frege’s criticism of [Boole’s] extensionalism. His confirmed extensionalism is a generalized version of the philosophy of science known as conventionalism. As such, it (...) places the advancement of science outside the province of science proper. It is, thus, at odds with Quine’s repeated expressions of alliance with the Popperian (hypothetico-deductive) model of science. (shrink)

Let us call dispositional monism the view that all natural properties have their identities fixed purely by their dispositional features, that is, by the patterns of stimulus and response in which they participate. DM implies that natural properties are pure powers: things whose natures are fully identified by their roles in determining the potentialities of events to cause or be caused. As pure powers, properties are meant to lack quiddities in Black's sense. A property possesses a quiddity just in case (...) its identity is fixed by something independent of the causal–nomological roles it may enter into. Paradigmatically, a categorical property is thought of as a property whose identity is fixed by a quiddity .The key question about the viability of DM as a theory of properties is how properties can be pure powers devoid of any quiddity. Bird provides an answer. According to Bird , ‘all there is to a property is a matter of second-order relations to other properties’. The second-order relation is just the relation that a disposition, its stimulus condition, and a manifestation condition bear to each other. Call this relation SR. SR is not causation or physical necessitation. The latter relations are first-order relations between concrete events. SR is a second-order relation. Its possession by properties explains why events featuring those properties can enter into certain first-order relations of causation or necessitation.Bird's thought then is this: the sense in which properties have their identities fixed purely by their causal–nomological roles is that they are relationally constituted, where the relation doing the constituting is SR. 1 This thesis of relational constitution does not imply that natural properties are themselves relations. Nothing prevents the identity …. (shrink)

All concepts, methods, and techniques of the philosophy of language arise from its conceptions of language. Conceptions of language have determined the character of the philosophy of language and the direction of its philosophical research. Various schools and currents within the philosophy of language differ from each other, mainly in the way they understand the referential character of the sign—that is, the relationship between the meaning of a word and its referential object.

We argue in favor of merely disjunctive effects, namely cases in which an event or fact, C, is not a cause of an effect, E1, and is also not a cause of a distinct effect, E2, and yet C is a cause of the disjunctive effect (E1 orE2). Disjunctive effects let us retain the additivity and the distributivity of causation. According to additivity, if C is a cause of E1 and C is a cause of E2, then C is a (...) cause of E1 and E2. According to distributivity, if C is a cause of E1 and E2, then C is a cause of E1 and C is a cause of E2. We draw an analogy between causation and intensional notions like believing, wanting, and owing, which also admit of merely disjunctive cases. We argue that both the Lewisian counterfactual account of causation (including its recent emendation by Sartorio) and the contrastive account of causation fail to properly account for this phenomenon.

_ Source: _Volume 95, Issue 2, pp 245 - 264 In the last few decades, the interest in Brentano’s philosophical psychology, especially in his theory of judgment, has been steadily growing.

These amendments constitute the focus of the present paper. As will be argued, only by making such changes can the weaknesses of (...) the first formulation of the theory be overcome. Moreover, as the final section of the paper attempts to show, these modifications may even trigger further steps towards what we might label a new Brentanian theory of judgment. (shrink)
