One usually makes assertions by means of uttering indicative sentences like “It is raining”. However, not every utterance of an indicative sentence is an assertion. For example, in uttering “I will be back tomorrow”, one might be making a promise. What is to make an assertion? C.S. Peirce held the view that “to assert a proposition is to make oneself responsible for its truth” (CP 5.543). In this thesis, I interpret Peirce’s view of assertion and I evaluate Peirce’s reasons for (...) holding it. I begin by reconstructing and assessing Peirce’s case for such view as it appears in (EP 2.140, 1903), (EP 2.312-313, 1904), and (CP 5.546, 1908). Then, I continue by elaborating on three aspects of Peirce’s view of assertion, namely, assertion as an act involving a certain kind of responsibility, the proposition as what is asserted, and responsibility for truth as a responsibility to give reasons. With respect to these three aspects, I argue for the following claims: (1) Peirce construed the responsibility involved in asserting as a moral responsibility; (2) Peirce held that propositions are types; and (3) Peirce was committed to a dialogical interpretation of “responsibility to give reasons”. Finally, I end by presenting two objections to Peirce’s view of assertion and its corresponding replies. I conclude that Peirce’s account of assertion is a valuable contribution to the philosophical debate on assertion. (shrink)

This study is an exploration of the place of perspectivism in the philosophy of Henri Bergson. His work is compared with that of Thomas Nagel in terms of the mutual concern of these two philosophers to reconcile our increasingly objecti vist and impersonal understanding of reality with the perspectival apprehension of the world that living and conscious beings instantiate. It argues that Bergson's philosophy of time holds the key both to comprehending and to balancing the demands made upon us by (...) these conflicting interests. It is seldom that Bergson's name is thought of in this connection, his concerns more often than not being identified with some thesis about time, movement, or vital forces. One purpose of the present work, therefore, is to contest this interpretive slant, not merely by offering an alternative image of Bergson, but also by critically exploring his employment of perspectivism (both positive and negative). We pursue this goal through the double strategy of both unravelling the inconsistencies in Bergson's· treatment of perspective and separating his own argument from the multitude of myths, opinions, and interpretations, sympathetic and unsympathetic, that have arisen around what is currently understood by "Bergsonism". In retrieving his thought from such philosophical ghettoes as "vitalism," "spiritualism," and "psychologism," we will argue for a Bergsonian perspectivism which ultimately resides in a thesis propounding the primacy of perception. One consequence of this is the demotion of memory's importance within his thought. Not that the orthodox image of Bergsonism that retains the privileged place of memory is wrong. Rather, we argue that there is enough in Bergson's peculiar picture of perception to obviate the need for memory in his philosophy, and, moreover, that it is actually more Bergsonian that memory should be so discharged.

This selective overview of the history of American Philosophy in the Twentieth Century begins with certain enduring themes that were developed by the two main founders of classical American pragmatism, Charles Sanders Peirce (1839--1914) and William James. Against the background of the pervasive influence of Kantian and Hegelian idealism in America in the decades surrounding the turn of the century, pragmatism and related philosophical outlooks emphasizing naturalism and realism were dominant during the first three decades of the century. Beginning in (...) the 1930s and 1940s, however, the middle third of the century witnessed the rising influence in America of what would become known as “‘analytic philosophy’,” with its primary roots in Europe: in the Cambridge philosophical analysis of Moore, Russell, and Wittgenstein; logical empiricism and positivism on the continent; and linguistic analysis and ordinary- language philosophy at Oxford. This overview stresses the persistence of pragmatist themes throughout much of the century, while emphasizing the mid-century transformations that resulted from developments primarily in analytic philosophy. These combined influences resulted at the turn of the millennium in the flourishing, among other developments, of distinctively analytic styles of pragmatism and naturalism. (shrink)

A number of traditional roles that propositions are supposed to play are outlined. Philosophical theories of the nature of propositions are then surveyed, together with considerations for and against, with an eye on the question whether any single notion of a proposition is suited to play all or any of these roles. Approaches discussed include: (1) the structureless possible-worlds theory; (2) the structured Russellian theory; and (3) the structured Fregean theory. It is noted that it is often unclear whether these (...) are accounts of what propositions are, ontologically speaking, or whether they are accounts of how propositions are best represented in a formal semantic theory.

The metaphysics of representation poses questions such as: in virtue of what does a sentence, picture, or mental state represent that the world is a certain way? In the first instance, I have focused on the semantic properties of language: for example, what is it for a name such as ‘London’ to refer to something? Interpretationism concerning what it is for linguistic expressions to have meaning, says that constitutively, semantic facts are fixed by best semantic theory. As here developed, it (...) promises to give a reductive, universal and non-revisionary account of the nature of linguistic representation. -/- Interpretationism in general, however, is threatened by severe internal tension, due to arguments for radical inscrutability. These contend that, given the interpretationist setting, there can be no fact of the matter what object an individual word refers to: for example, that there is no fact of the matter as to whether “London” refers to London or to Sydney. -/- A series of challenges emerge, forming the basis for this thesis. 1. What sort of properties is the interpretationist trying to reduce, and what kind of reductive story is she offering? 2. How are inscrutability theses best formulated? Are arguments for inscrutability effective in their own terms? What kinds of inscrutability arise? 3. Is endorsing radical inscrutability a stable position? 4. Are there theoretical virtues—such as simplicity—that can be appealed to in discrediting the rival (empirically equivalent) theories that underpin inscrutability arguments? -/- In addressing these questions, I concentrate on diagnosing the source of inscrutability, mapping the space of ways of resisting the arguments for radical inscrutability, and examining the challenges faced in developing a principled account of linguistic content that avoids radical inscrutability. -/- The effect is not to close down the original puzzles, but rather to sharpen them into a set of new and deeper challenges.

The paper concentrates on the most pressing question of Indian philosophy: what is the exact connotation of a word or what sort of entity helps us to identify the meaning of a word? The paper focuses on the clash between Realism (Nyāya) and Apoha vāda (Buddhist) regarding the debate whether the meaning of a word is particular/universal or both. The paper asserts that though Naiyāyikas and Mīmāṁsakas challenged against Buddhist Apoha vāda, yet they realized that to establish an opinion in (...) support of a word that conceptually denotes a negative meaning first would be a very difficult task.

We present a sound and complete Fitch-style natural deduction system for an S5 modal logic containing an actuality operator, a diagonal necessity operator, and a diagonal possibility operator. The logic is two-dimensional, where we evaluate sentences with respect to both an actual world (first dimension) and a world of evaluation (second dimension). The diagonal necessity operator behaves as a quantifier over every point on the diagonal between actual worlds and worlds of evaluation, while the diagonal possibility quantifies over some point (...) on the diagonal. Thus, they are just like the epistemic operators for apriority and its dual. We take this extension of Fitch’s familiar derivation system to be a very natural one, since the new rules and labeled lines hereby introduced preserve the structure of Fitch’s own rules for the modal case.

Some philosophers of mind have argued for considering consciousness as a further fundamental feature of reality in addition to its physical properties. Hence most of them are property dualists. But some of them are panpsychists. In the present paper it will be argued that being a real property dualist essentially entails being a panpsychist. Even if panpsychism deals rather elegantly with certain problems of the puzzle of consciousness, there’s no way around the composition problem. Adhering to the fundamentality claim of (...) the mind, it will be shown that only a radical revision of metaphysics will allow the panpsychist to avoid these troubles, and hence that a panpsychist must adopt Leibnizian idealism.

A number of philosophers have recently suggested that the role of intuitions in the epistemology of armchair philosophy has been exaggerated. This suggestion is rehearsed and endorsed. What bearing does the rejection of the centrality of intuition in armchair philosophy have on experimentalist critiques of the latter? I distinguish two very different kinds of experimentalist critique: one critique requires the centrality of intuition; the other does not.

The aim of this thesis is to increase our ontological understanding of musical works in two ways. We’ll increase our understanding of their categorial nature and we’ll increase our understanding of what the identity of each musical work consists in. In chapter 1, I introduce the basic question of the thesis: what are musical works? This question is broken down into four separate questions which guide the structure and argument of the thesis. One question asks if musical works exist, the (...) other asks about the ontological category to which musical works belong. In the first half of the thesis, I argue that musical works exist and that the best explanation of their features is given by assigning them to the category of universals. I argue for this conclusion by elaborating and defending a view according to which musical works are properties. I then show that this conception is superior to the strongest rivals. One rival takes musical works to be historical individuals (Rohrbaugh 2003). The other takes them to be actions of composition (Davies 2004). In chapter 6, I turn to two questions about identity. One question asks about the identity criteria for musical works, the other question asks for an explanation of musical work identity. In the remainder of chapter 6, I argue by reference to contextualist intuitions that a superficially appealing view, sonicism is problematic. The critique of sonicism is used to draw out certain contextualist assumptions that our ontology of music ought to explain. In chapter 7, I examine a family of Levinsonian contextualist proposals. I argue that the original formulations (Levinson 1980) give incorrect results, and that attempts to modify them (Davies, S: 2001) slip into obscurity, or undermine the aims of the project (Levinson 1992). I end chapter 7 by presenting the performance theory in a more flattering light. I argue that as a theory of musical work identity, the performance theory is the best on the market because it overcomes the problems associated with the Levinsonian views and deepens our understanding of contextualist intuitions. In chapter 8, I present an account of the ontology of music which integrates the property theory of category with the performance theory of identity by construing musical works as impure relational properties. I then defend the integrated account against various objections. In this defence, I elaborate a view of compositional actions as belonging to the ontological category of processes. (shrink)

A non-relativistic quantum mechanical theory is proposed that describes the universe as a continuum of worlds whose mutual interference gives rise to quantum phenomena. A logical framework is introduced to properly deal with propositions about objects in a multiplicity of worlds. In this logical framework, the continuum of worlds is treated in analogy to the continuum of time points; both “time” and “world” are considered as mutually independent modes of existence. The theory combines elements of Bohmian mechanics and of Everett’s (...) many-worlds interpretation; it has a clear ontology and a set of precisely defined postulates from where the predictions of standard quantum mechanics can be derived. Probability as given by the Born rule emerges as a consequence of insufficient knowledge of observers about which world it is that they live in. The theory describes a continuum of worlds rather than a single world or a discrete set of worlds, so it is similar in spirit to many-worlds interpretations based on Everett’s approach, without being actually reducible to these. In particular, there is no splitting of worlds, which is a typical feature of Everett-type theories. Altogether, the theory explains (1) the subjective occurrence of probabilities, (2) their quantitative value as given by the Born rule, and (3) the apparently random “collapse of the wavefunction” caused by the measurement, while still being an objectively deterministic theory.

This is one of a series of articles in which I examine errors that philosophers of language may be led to make if already prone to exaggerating the rôle compositional semantics can play in explaining how we communicate, whether by expressing propositions with our words or by merely implying them. In the present article, I am concerned less with “pragmatic contributions” to the propositions we express—contributions some philosophers seem rather desperate to deny the existence or ubiquity of—than I am with (...) certain types of traps that those who exaggerate the rôle of semantic convention and underestimate the rôle of pragmatic inference are apt to fall into.

What is the distinctively philosophical problem of perception? Here it is argued that it is the conflict between the nature of perceptual experience as it intuitively seems to us, and certain possibilities which are implicit in the very idea of experience: possibilities of illusion and to the world' which involves direct awareness of existing objects and their properties. But if one can have an experience of the same kind without the object being there -- a hallucination of an object -- (...) then it seems that perceptual experience cannot essentially be such a relation. This is the fundamentally philosophical problem of perception; the various philosophical theories of perception in the 20th and 21st centuries can be seen as responses to it. (shrink)

Timothy Williamson’s Knowledge and its Limits has been highly influential since the beginning of this century. It can be read as a systematic response to scepticism. One of the most important notions in this response is the notion of «evidence,» which will be the focus of the present paper. I attempt to show primarily two things. First, the notion of evidence invoked by Williamson does not address the sceptical worry: he stipulates an objective notion of evidence, but this begs the (...) question against his opponent. Second, his related thesis «Evidence equals Knowledge» does not sit well with his own content externalism: he promises to relate epistemology to philosophy of mind, but he fails to live up to this commitment in his crucial chapter on scepticism. Other minor problems concerning evidence will also be discussed in due course. (shrink)

Scientific models are important, if not the sole, units of science. This thesis addresses the following question: in virtue of what do scientific models represent their target systems? In Part i I motivate the question, and lay out some important desiderata that any successful answer must meet. This provides a novel conceptual framework in which to think about the question of scientific representation. I then argue against Callender and Cohen’s attempt to diffuse the question. In Part ii I investigate the (...) ideas that scientific models are ‘similar’, or structurally morphic, to their target systems. I argue that these approaches are misguided, and that at best these relationships concern the accuracy of a pre-existing representational relationship. I also pay particular attention to the sense in which target systems can be appropriately taken to exhibit a ‘structure’, and van Fraassen’s recent argument concerning the pragmatic equivalence between representing phenomena and data. My next target is the idea that models should not be seen as objects in their own right, but rather what look like descriptions of them are actually direct descriptions of target systems, albeit not ones that should be understood literally. I argue that these approaches fail to do justice to the practice of scientific modelling. Finally I turn to the idea that how models represent is grounded, in some sense, in their inferential capacity. I compare this approach to anti-representationalism in the philosophy of language and argue that analogous issues arise in the context of scientific representation. Part iii contains my positive proposal. I provide an account of scientific representation based on Goodman and Elgin’s notion of representation-as. The result is a highly conventional account which is the appropriate level of generality to capture all of its instances, whilst remaining informative about the notion. I illustrate it with reference to the Phillips-Newlyn machine, models of proteins, and the Lotka-Volterra model of predator-prey systems. These examples demonstrate how the account must be understood, and how it sheds light on our understanding of how models are used. I finally demonstrate how the account meets the desiderata laid out at the beginning of the thesis, and outline its implications for further questions from the philosophy of science; not limited to issues surrounding the applicability of mathematics, idealisation, and what it takes for a model to be ‘true’.

This paper examines pain states (and other intransitive bodily sensations) from the perspective of the problems they pose for pure informational/representational approaches to naturalizing qualia. I start with a comprehensive critical and quasi-historical discussion of so-called Perceptual Theories of Pain (e.g., Armstrong, Pitcher), as these were the natural predecessors of the more modern direct realist views. I describe the theoretical backdrop (indirect realism, sense-data theories) against which the perceptual theories were developed. The conclusion drawn is that pure representationalism about pain (...) in the tradition of direct realist perceptual theories (e.g., Dretske, Tye) leaves out something crucial about the phenomenology of pain experiences, namely, their affective character. I touch upon the role that introspection plays in such representationalist views, and indicate how it contributes to the source of their trouble vis-à-vis bodily sensations. The paper ends by briefly commenting on the relation between the affective/evaluative component of pain and the hedonic valence of emotions. (shrink)

Was ist das überhaupt – Bewußtsein? Beim Gebrauch des Substantivs „Bewußt- sein“ sollte man eine gewisse Vorsicht walten lassen. Die deutsche Sprache kennt dieses Substantiv nur innerhalb weniger Redewendungen – „Dann verlor er das Bewußtsein“, „Nach vielen Stunden kam er wieder zu Bewußtsein“, „Im Bewußtsein seiner schweren Verantwortung“ usw. Außerhalb dieser Redewen- dungen kommt das Wort dagegen praktisch nicht vor; und deshalb sollte man skeptisch werden, wenn Philosophen Sätze formulieren wie „Menschen haben ein Bewußtsein“. „Bei Bewußtsein sein“ ist gebräuchliches Deutsch, (...) „ein Be- wußtsein haben“ nicht.1 Diese Bemerkungen mahnen zwar zu besonderer Vor- sicht, helfen in der Sache jedoch nicht viel weiter.

Semantic holism has it that the semantic properties of an individual expression are determined by that expression.

Wenn es aber Wirklichkeitssinn gibt, und niemand wird bezweifeln, daß er seine Daseinsberechtigung hat, dann muß es auch etwas geben, das man Möglichkeitssinn nennen kann. Wer ihn besitzt, sagt beispielsweise nicht: Hier ist dies oder das geschehen, wird geschehen, muß geschehen; sondern er erfindet: Hier könnte, sollte oder müßte geschehn; und wenn man ihm von irgend etwas erklärt, daß es so sei, wie es sei, dann denkt er: Nun, es könnte wahrscheinlich auch anders sein.

There are two sorts of singular terms for which we have difficulty applying Donnellan’s referential/attributive distinction: complex definite descriptions, and proper names. With respect to the uses of such terms in certain contexts we seem to have conflicting intuitions as to whether they should be classified as referential or attributive. The problem concerning how to apply Donnellan’s distinction to the uses of certain complex definite descriptions has never been debated in the literature. On the other hand there have been attempts (...) to extend Donnellan’s distinction to the uses of proper names, the most popular one being due to Kripke. However the argument Kripke gives to this end in his ‘Speaker’s Reference and Semantic Reference’ seems to be inconsistent with the position he takes in Naming and Necessity. I suggest that the reason we seem to have conflicting intuitions with respect to the uses of such terms, is because there is not one but two separate distinctions inherent in Donnellan’s examples; a pragmatic distinction based on the speaker’s intentions in using a term , and an epistemic one based on the notion of having an object in mind. In the light of this, I argue that the issue of whether there are attributive uses of proper names, in the latter sense, relates to the epistemic problem of whether a speaker can have de re attitudes toward an object that he does not have in mind. On this epistemic issue Kripke and Donnellan are on opposite sides as revealed by their debate over the issue of whether there are contingent a priori propositions. (shrink)

In A Puzzle About Belief, Saul Kripke tells the story of a person caught in a classic Frege case. Peter is unaware that Paderewski the famous Polish politician, and Paderewski the famous Polish musician, are one and the same person. What is supposed to distinguish this Frege case from many others is that Peter associates a single name, 'Paderewski' with both of his conceptions. But not everyone may agree with this description. Richard Larson and Peter Ludlow, and Robert Fiengo and (...) Robert May have suggested that Peter's idiolect contains two 'Paderewski' names (or syntactic expressions). Just as ordinary English speakers may have two 'bank' words each with its own meaning, Peter has two homophonic names each corresponding to one of his conceptions of Paderewski. I will call this position, which will be subject to further clarification, 'the two-name view'. According to the two-name view, the syntactic facts concerning an agent's language should reflect, in this peculiar way, her own perspective on the world. In this sense then, the two-name view is a symptom of an individualistic conception of the words that make up a person's language. (shrink)

A new understanding of the objectifying process in science is gained if one considers it in the framework of the open, dynamical and holistic model of knowledge developed by Ernst Cassirer to overcome the problems of Kantian epistemology, which allows to consider transitoriness and contingency as integral parts of knowledge. Using physics as a concrete example it is examined, how the fundamental tasks of constitution and justification of knowledge can be understood differently within this model and to what extent this (...) allows to clarify still controversial interpretational questions (especially in quantum mechanics). Therein the creation of symbolical order -patterns and the purely pragmatic confirmation of even the foundations of knowledge are of central relevance. (shrink)

Neurological syndromes in which consciousness seems to malfunction, such as temporal lobe epilepsy, visual scotomas, Charles Bonnet syndrome, and synesthesia offer valuable clues about the normal functions of consciousness and ‘qualia’. An investigation into these syndromes reveals, we argue, that qualia are different from other brain states in that they possess three functional characteristics, which we state in the form of ‘three laws of qualia’. First, they are irrevocable: I cannot simply decide to start seeing the sunset as green, or (...) feel pain as if it were an itch; second, qualia do not always produce the same behaviour: given a set of qualia, we can choose from a potentially infinite set of possible behaviours to execute; and third, qualia endure in short-term memory, as opposed to non-conscious brain states involved in the on-line guidance of behaviour in real time. We suggest that qualia have evolved these and other attributes because of their role in facilitating non-automatic, decision-based action. We also suggest that the apparent epistemic barrier to knowing what qualia another person is experiencing can be overcome by using a ‘bridge’ of neurons; and we offer a hypothesis about the relation between qualia and one's sense of self.

Intentionality may be dealt with in two different ways: either ontologically, as an ordinary relation to some extraordinary objects, or epistemologically, as an extraordinary relation to some ordinary objects. This paper endorses the epistemological view in order to provide a model of semiotic intentionality defined as the meaning-and-cognizing process that constitutes to power of the mind to be about something on the basis of a semiotic system. After a short introduction that presents the components of semiotic intentionality (viz. sign, act, (...) content, referent) along with their division into an intending and a fulfilling side (Sect. 1), the first main part of the paper analyzes semiotic intentionality at its primary level (a.k.a. 'concrete intentionality') as a real and subjective relation between meaning-intending and meaning-fulfilling acts grounded in the manipulation of some semiotic system (Sect. 2). Then, building on such concrete intentionality, the second main part of the paper analyzes semiotic intentionality at its secondary level (a.k.a. 'abstract intentionality') as an ideal and objective relation between intentional and fulfillment contents, which in turn: (i) proceed from an abstraction performed on the intending and fulfilling acts, respectively, and (ii) retroactively categorize the intending and fulfilling acts, respectively (Sect. 3). Finally, from this combination of an act-based conception of content with a presentationalist account of intentionality, the conclusion of this paper produces the intended model of semiotic intentionality in such a way that knowledge and truth are then respectively defined in it as the subjective correspondence between the two acts of concrete intentionality and as the objective correspondence between the two contents of abstract intentionality (Sect. 4).

This thesis deals with the phenomenon of attitude reporting. More specifically, it provides a unified semantics of de re and de se belief reports. After arguing that de se belief is best thought of as a special case of de re belief, I examine whether we can extend this unification to the realm of belief reports. I show how, despite very promising first steps, previous attempts in this direction ultimately fail with respect to some relatively recent linguistic data involving quantified (...) and infinitival reports, logophoric constructions, and monstrously shifted indexicals. Formalizing my idea of a contextual resolution of acquaintance relations in a dynamic framework, I arrive at an alternative analysis that handles all these data. (shrink)

Functionalism, which views consciousness as the product of the processing of stimuli by the brain, is perhaps the dominant view among researchers in the cognitive sciences and associated fields. However, as a workable scientific model of consciousness, it has been marred by a singular lack of tangible success, except at the broadest levels of explanation. This paper argues that this is not an accident, and that in its standard construal it is simply too unwieldy to assume the burden of full-fledged (...) theory. In its place, a reduced functionalism is introduced by applying the principle of parsimony successively to the elements of standard functionalism until only a minimal framework remains. This simpler account states that consciousness is a function of instantaneous causal relations between processing elements rather the putative algorithm such relations are instantiating. It is then argued as a corollary that the only such relations that matter are those in which reciprocal influences are at play. Thus, purely afferent and efferent causal relations are pruned from consideration. The theory resulting from the addition of this corollary is shown to have good correspondence with a number of recent neurophysiologically-motivated approaches to consciousness, including those that stress the importance of reentry, those that view synchrony as a key independent variable, and those that highlight the importance of the accessibility of conscious contents to multiple processing modules. In addition, the theory is shown to be consistent with recent results in the literature on masking, and those in the literature on binocular rivalry. The paper concludes by arguing that the theoretical and empirical difficulties inherent in consciousness research imply that the principle of parsimony must occupy a more central role in consciousness research than it would in ordinary scientific discourse.

Accounts of modal knowledge are many and varied. How should we choose between them? I propose that we employ inference to the best explanation, and I suggest that there are three desiderata that we should use to rank hypotheses: conservatism, simplicity, and the ability to handle disagreement. After examining these desiderata, I contend that they can’t be used to justify belief in the modal epistemology that fares best, but that they can justify our accepting it in an epistemically significant sense. (...) Finally, I outline a modal epistemology that seems to do well by the standards I’ve recommended. (shrink)

Many contemporary philosophers are committed – either implicitly or explicitly – to Propositionalism about thought-experimental intuitions. According to this view, thought-experimental intuitions are phenomenally conscious, spontaneous, and non-theoretical; most importantly, Propositionalists claim that intuitions bear consciously accessible propositional content. The negative project of this essay is a critique of, the rejection of which is tantamount to rejecting Propositionalism. In addition, I propose an alternative position – namely, Interpretationalism. According to Interpretationalism, intuitions possess the features ascribed in -; however, they do (...) not bear consciously accessible propositional content. Instead, intuitions acquire cognitive significance by virtue of being interpreted in light of a subject’s background beliefs. (shrink)

In this paper I examine the connection between symmetry and modality from the perspective of `reduction' methods in geometric mechanics. I begin by setting the problem up as a choice between two opposing views: reduction and non-reduction. I then discern four views on the matter in the literature; they are distinguished by their advocation of distinct geometric spaces as representing `reality'. I come down in favour of non-reductive methods.

I survey some of the connections between the metaphysics of the relation between mind and matter, and quantum theory’s measurement problem. After discussing the metaphysics, especially the correct formulation of physicalism, I argue that two state-reduction approaches to quantum theory’s measurement problem hold some surprises for philosophers’ discussions of physicalism. Though both approaches are compatible with physicalism, they involve a very different conception of the physical, and of how the physical underpins the mental, from what most philosophers expect. And one (...) approach exemplifies a a problem in the definition of physicalism which the metaphysical literature has discussed only in the abstract. A version of the paper has appeared in Consciousness and Human Identity, ed. John Cornwell, OUP 1998. (shrink)

In this dissertation, I argue that we should be pluralists about truth and in turn, eliminativists about the property Truth. Traditional deflationists were right to suspect that there is no such property as Truth. Yet there is a plurality of pluralities of properties which enjoy defining features that Truth would have, were it to exist. So although, in this sense, truth is plural, Truth is non-existent. The resulting account of truth is indebted to deflationism as the provenance of the suspicion (...) that Truth doesn't exist. But it would be hasty to simply classify the account as deflationary. Each of the 'truth-like' properties that it recognizes is highly substantive--that is, complex and explanatorily potent. So we should deflate Truth by recognizing that it doesn't exist, but we should also recognize that one of the most vital tasks in truth theory is to discover the essences of the many truth-like properties. My aim here is to do precisely this. (shrink)

Philosophers love a priori knowledge: we delight in truths that can be known from the comfort of our armchairs, without the need to venture out in the world for confirmation. This is due not to laziness, but to two different considerations. First, it seems that many philosophical issues aren’t settled by our experience of the world — the nature of morality; the way concepts pick out objects; the structure of our experience of the world in which we find ourselves — (...) these issues seem to be decided not on the basis of our experience, but in some manner by things prior to (or independently of) that experience. Second, even when we are deeply interested in how our experience lends credence to our claims about the world, the matter remains of the remainder: we learn more about how experience contributes to knowledge when we see what knowledge is available independent of that experience.

Discutindo acerca das centenas de detecções de planetas extrassolares, que supostamente aconteceram desde 1989 e que ele considera (incorretamente) como instâncias de observações, Peter Kosso disse, justamente, que segundo os parâmetros de Bas van Fraassen esses objetos celestes seriam observáveis. Ora, tais astros poderiam sem dúvida ser observados diretamente (sem a necessidade de instrumentos), nas condições apropriadas. Mas, acrescenta Kosso, “esse tipo de epistemologia externalista, que permite que a justificação se baseie em informação que não temos a disposição (nós não (...) estamos em condição de ver planetas extrassolares a olho nu [atualmente]), não ajuda a decidir quais particulares afirmações científicas garantem a crença” (Kosso 2006, 225, nota 1). Van Fraassen provavelmente incorre em uma petição de princípio não muito diferente daquelas que ele muitas vezes desmascarou em textos de autores realistas, quando apela para o fato de o objeto detectado ser observável, para atribuir o estatuto de ‘observação’ a uma certa detecção. O ponto é, mais uma vez, entender o que vale como observação, particularmente quando isso envolve o uso de algum instrumento. Endossar aquilo que Otávio Bueno chama de ‘padrão internalista’ parece garantir solidez à qualificação de determinadas ações como observações. Uma das principais consequências dessa adoção é que tal critério, não operando nenhuma distinção relevante entre detecções ‘diretas’ e detecções mediadas por instrumentos, permite que a linha que separa observáveis e inobserváveis seja traçada de maneira diferente de como van Fraassen acredita que deveria ser, abarcando, entre os observáveis, mais (tipos de) entidades do que esse parece estar disposto a admitir.

In (1959), Carnap famously attacked Heidegger for having constructed an insane metaphysics based on a misconception of both the logical form and the semantics of ordinary language. In what follows, it will be argued that, once one appropriately (i.e., in a Russellian fashion) reads Heidegger’s famous sentence that should paradigmatically exemplify such a misconception, i.e., “the nothing nothings”, there is nothing either logically or semantically wrong with it. The real controversy as to how that sentence has to be evaluated—not as (...) to its meaning but as to its truth—lies at the metaphysico- ontological level. For in order for the sentence to be true one has to endorse an ontology of impossibilia and Leibniz’s principle of the identity of indiscernibles. (shrink)

Fictional realism allows direct reference theorists to provide a straightfor- ward analysis of the semantics of fictional discourse by admitting into their ontology a set of objects (ficta) that serve as the referents of fictional names. Ficta may be modeled using an axiomatic object theory, but actualist interpretations of the formalism have been the subject of recent objections. In this paper, I provide an interpretation of object theory’s formalism that is consistent with actualism and avoids these objections. Drawing on insights (...) from an actualist semantics for quantified modal logic, a central point in my proposal is to interpret ficta as contingently nonconcrete objects. (shrink)
