In this paper, we explore the idea that sets depend on, or are grounded in, their members. It is said that a set depends on each of its members, and not vice versa. Members do not depend on the sets that they belong to. We show that the intuitive modal truth conditions for dependence, given in terms of possible worlds, do not accurately capture asymmetric dependence relations between sets and their members. We extend the modal truth conditions to include impossible (...) worlds and give a more satisfactory account of the dependence of a set on its members. Focusing on the case of singletons, we articulate a logical framework in which to evaluate set-theoretic dependence claims, using a normal first-order modal logic. We show that on this framework the dependence of a singleton on its single members follows from logic alone. However, the converse does not hold. (shrink)

A popular response to the Exclusion Argument for physicalism maintains that mental events depend on their physical bases in such a way that the causation of a physical effect by a mental event and its physical base needn’t generate any problematic form of causal overdetermination, even if mental events are numerically distinct from and irreducible to their physical bases. This paper presents and defends a form of dualism that implements this response by using a dispositional essentialist view of properties to (...) argue that the psychophysical laws linking mental events to their physical bases are metaphysically necessary. I show the advantages of such a position over an alternative form of dualism that merely places more “modal weight” on psychophysical laws than on physical laws. The position is then defended against the objection that it is inconsistent with dualism. Lastly, some suggestions are made as to how dualists might clarify the contribution that mental causes make to their physical effects. (shrink)

An influential proposal is that knowledge involves safe belief. A belief is safe, in the relevant sense, just in case it is true in nearby metaphysically possible worlds. In this paper, I introduce a distinct but complementary notion of safety, understood in terms of epistemically possible worlds. The main aim, in doing so, is to add to the epistemologist’s tool-kit. To demonstrate the usefulness of the tool, I use it to advance and assess substantive proposals concerning knowledge and justification.

According to phenomenal conservatism, seemings can provide prima facie justification for beliefs. In order to fully assess phenomenal conservatism, it is important to understand the nature of seemings. Two views are that (SG) seemings are a sui generis propositional attitude, and that (D2B) seemings are nothing over and above dispositions to believe. Proponents of (SG) reject (D2B) in large part by providing four distinct objections against (D2B). First, seemings have a distinctive phenomenology, but dispositions to believe do not. Second, seemings (...) can provide a non-trivial explanation for dispositions to believe, which wouldn’t be possible if seemings were dispositions to believe. Third, there are some dispositions to believe that are not seemings. Fourth, there are instances of seemings which are not dispositions to believe. I consider and reject each of these objections. The first and third objections rely on a misunderstanding of (D2B). The second objection fails because there are contexts in which an appeal to a previously unknown identity can provide an interesting explanation. The fourth objection overlooks the possibility of finkish and masked dispositions, phenomena which are widely accepted in the dispositions literature. I conclude that (D2B) escapes these common objections unscathed. (shrink)

Are mental disorders natural kinds or socially constructed categories? What is at stake if either of these views prove to be true? This paper offers a qualified defence for the view that there may be natural kinds of mental disorder, but also that the implications of this claim are generally overestimated. Especially concerns about over-inclusiveness of diagnostic categories and medicalisation of abnormal behaviour are not addressed by the debate. To arrive at these conclusions the paper opens with a discussion of (...) kind formation in science, followed by an analysis of natural kinds. Seven principled and empirically informed objections to the possibility of natural kinds of mental disorder are considered and rejected. The paper ends with a reflection on diagnostics of mental health problems that don’t fall into natural kinds. Despite the defence of the possibility of natural kinds of mental disorder, this is likely to be the majority of cases. (shrink)

The purpose of the present paper is to challenge some received assumptions about the logical analysis of modal English, and to show that these assumptions are crucial to certain debates in current philosophy of language. Specifically, I will argue that the standard analysis in terms of quantified modal logic mistakenly fudges important grammatical distinctions, and that the validity of Kripke's modal argument against description theories of proper names crucially depends on ensuing equivocations.

Realist philosophies of science posit a dialectical relation between theoretical, explanatory knowledge and practical, including taxonomic knowledge. This paper examines the dialectic between the theory of descent and empirical, Linnaean taxonomy which is based on a logic of traditional classes. It considers the arguments of David Hull to the effect that many of the practical problems of empirical classification can be resolved by means of an ontology based upon the theory of descent in which species taxa are regarded as individuals (...) rather than as classes or natural kinds.Contra Hull, it is argued that this view is, at best, only partially consistent with taxonomic practice and that it cannot sustain experimental practice which presupposes that species taxa be regarded as natural kinds. An outline is given of a possible alternative dialectic between a field theory of morphogenesis and a rational systematics involving a logic of relations. (shrink)

Recently four different papers have suggested that the supervaluational solution to the Problem of the Many is flawed. Stephen Schiffer (1998, 2000a, 2000b) has argued that the theory cannot account for reports of speech involving vague singular terms. Vann McGee and Brian McLaughlin (2000) say that theory cannot, yet, account for vague singular beliefs. Neil McKinnon (2002) has argued that we cannot provide a plausible theory of when precisifications are acceptable, which the supervaluational theory needs. And Roy Sorensen (2000) argues (...) that supervaluationism is inconsistent with a directly referential theory of names. McGee and McLaughlin see the problem they raise as a cause for further research, but the other authors all take the problems they raise to provide sufficient reasons to jettison supervaluationism. I will argue that none of these problems provide such a reason, though the arguments are valuable critiques. In many cases, we must make some adjustments to the supervaluational theory to meet the posed challenges. The goal of this paper is to make those adjustments, and meet the challenges. (shrink)

This paper discusses the coverage of ordinary language philosophy in Scott Soames' Philosophical Analysis in the Twentieth Century. After praising the book's virtues, I raise three points where I dissent from Soames' take on the history. First, I suggest that there is more to ordinary language philosophy than the rather implausible version of it that Soames sees to have been destroyed by Grice. Second, I argue that confusions between analyticity, necessity and priority are less important to the ordinary language period (...) than Soames takes them to be. Finally, I claim that Soames' criticisms of Ryle turn in part on attributing reductionist positions to Ryle that Ryle did not hold. (shrink)

We present an approach to combining three areas of research which we claim are all based on information theory: knowledge representation in Artificial Intelligence and Cognitive Science using prototypes, plans, or schemata; formal semantics in natural language, especially the semantics of the `if-then' conditional construct; and the logic of subjunctive conditionals first developed using a possible worlds semantics by Stalnaker and Lewis. The basic premise of the paper is that both schema-based inference and the semantics of conditionals are based on (...) Dretske's notion of information flow and Barwise and Perry's notion of a constraint in situation semantics. That is, the connection between antecedent and consequent of a conditional `if were the case then would be the case' is an informational relation holding with respect to a pragmatically determined utterance situation. The bridge between AI and conditional logic is that a prototype or planning schema represents a situation type, and the background assumptions underlying the application of a schema in a situation correspond to channel conditions on the flow of information. Adapting the work of Stalnaker and Lewis, the semantics of conditionals is modeled by a refinement ordering on situations: a conditional `if then ' holds with respect to a situation if all the minimal refinements of the situation that support also support . We present new logics of situations, information flow, and subjunctive conditionals based on three-valued partial logic that formalizes our approach, and conclude with a discussion of the resulting theory of conditionals, including the "paradoxes" of conditional implication, the difference between truth conditions and assertability conditions for subjunctive conditionals, and the relationship between subjunctive and indicative conditionals.

In Kripke-semantics for modal logic, the truth value of a sentence depends on the choice of a semantic index. It means that application of such semantics to natural language analysis requires indication of an index relevant for semantic analysis. It is commonly accepted that the relevant index is initialised by the context of an utterance. The idea has been rejected by the semanticists investigating tempo-modal languages in the framework of indeterminism, which generated the problem of initialization of the semantic index. (...) I present the main argument of those semanticists and describe several responses to the initialisation problem. I finally argue that under certain metaphysical and semantic assumptions, one can respond to the initialisation failure in the classical way, even in indeterministic contexts. (shrink)

There is a long-standing disagreement among Branching-Time theorists. Even though they all believe that the branching representation accurately grasps the idea that the future, contrary to the past, is open, they argue whether this representation is compatible with the claim that one among many possible futures is distinguished—the single future that will come to be. This disagreement is paralleled in an argument about the bivalence of future contingents. The single, privileged future is often called the Thin Red Line. I reconstruct (...) the history of the arguments for and against this idea. Then, I propose my own version of the Thin Red Line theory which is immune to the major objections found in the literature. I argue that the semantic disagreement is grounded in distinct metaphysical presuppositions. My solution is expressed in a conceptual framework proposed by John MacFarlane, who distinguishes semantics from postsemantics. I extend his distinction and introduce a new notion of presemantics to elucidate my idea. (shrink)

Recent criticisms of non-reductive accounts of color assume that the only arguments for such accounts are a priori arguments. I put forward a posteriori arguments for a non-reductive account of colors which avoids those criticisms.

This paper argues that a priori justification is, in principle, compatible with naturalism—if the a priori is understood in a way that is free of the inessential properties that, historically, have been associated with the concept. I argue that empirical indefeasibility is essential to the primary notion of the a priori ; however, the indefeasibility requirement should be interpreted in such a way that we can be fallibilist about apriori-justified claims. This fallibilist notion of the a priori accords with the (...) naturalist’s commitment to scientific methodology in that it allows for apriori-justified claims to be sensitive to further conceptual developments and the expansion of evidence. The fallibilist apriorist allows that an a priori claim is revisable in only a purely epistemic sense. This modal claim is weaker than what is required for a revisability thesis to establish empiricism, so fallibilist apriorism represents a distinct position. (shrink)

Modal primitivists hold that some modal truths are primitively true. They thus seem to face a special epistemological problem: how can primitive modal truths be known? The epistemological objection has not been adequately developed in the literature. I undertake to develop the objection, and then to argue that the best formulation of the epistemological objection targets all realists about modality, rather than the primitivist alone. Furthermore, the moves available to reductionists in response to the objection are also available to primitivists. (...) I conclude by suggesting that extant theories of the epistemology of modality are not sensitive to the question of primitivism versus reductionism. (shrink)

Hilary Putnam made the claim several times that the direct reference theory (DRT) he endorsed had startling consequences for the theory of necessary truth and essentialism. If DRT was correct, so he claimed, it followed that things belonging to natural kinds had their deep structures necessarily. Inspired by Keith Donnellan, Nathan Salmon tried to spell out what Putnam seemed to have in mind when making the claim, and Salmon called the result of his analysis “the OK mechanism.” Salmon showed that (...) it was not DRT, but some other essentialism-entailing premise, that had the claimed startling consequences in the OK mechanism. In this paper, I argue that Salmon’s OK is not the right interpretation of Putnam’s intended mechanism. Instead, I present Putnam’s intention as the OK* mechanism, and show that, in OK*, DRT does have the claimed startling consequences when supplemented only with other metaphysically innocent, purely empirically verifiable premises.

Williamson ( 2007 ) argues that philosophers acquire no philosophical knowledge at all by semantic understanding alone. He further argues that the most important method used for achieving philosophical knowledge is through the ‘imaginative simulation’ process some of whose products are neither a priori nor a posteriori but ‘armchair’ knowledge. We argue in this paper that the way Williamson argues against the claim that semantic understanding alone is enough to achieve philosophical knowledge can be paralleled by an exactly similar argument (...) against his view that imaginative simulation alone is enough to achieve philosophical knowledge. Because of the parallel argument, we conclude that Williamson’s argument against semantic understanding shows at most that it is fallible, if used alone, as a method for achieving philosophical knowledge. We also point out a blind spot in Williamson’s argument for his epistemology of modality: a reliable method for achieving knowledge about subjunctive conditionals is not necessarily a reliable method for achieving knowledge about modal statements even if every modal statement is logically equivalent to some subjunctive conditional. Finally, we argue that, with a suitable understanding of ‘understanding the meaning,’ Williamson’s armchair knowledge is nothing but the a priori knowledge of those good-old-days philosophy.

Michael Dummett argues, against Saul Kripke, that there could have been unicorns. He then claims that this possibility shows that the logic of metaphysical modality is not S5, and, in particular, that the B axiom is false. Dummett’s argument against B, however, is invalid. I show that although there are number of ways to repair Dummett’s argument against B, each requires a controversial metaphysical or semantic commitment, and that, regardless of this, the case against B is undermotivated. Dummett’s case is (...) still of interest, however, as if his assumptions are correct, S5 has to go, with the natural culprit being S4. (shrink)

It is argued that philosophers who adopt the perdurance theory of persistence and who subscribe to the principle of Unrestricted Mereological Composition (UMC) are in a position to regard “Phosphorus is Hesperus” as false.

In Elder-Vass’s response to my critical discussion of his social ontology, it is maintained (1) that a social object is not identical with but is merely composed of its suitably interrelated parts, (2) that a social object is necessarily indistinguishable in terms of its causal capacities from its interrelated parts, and (3) that ontological individualism lacks an adequate ontological justification. In this reply, I argue that in view of (1) the so-called redescription principle defended by Elder-Vass ought to be reformulated (...) and renamed; that the conjunction of (1) and (2) renders social objects causally redundant; and that ontological individualism can be coherently formulated and theoretically justified within Elder-Vass’s own metaphysics of objects with causal powers.

The Principal Principle (PP) says that, for any proposition A, given any admissible evidence and the proposition that the chance of A is x%, one's conditional credence in A should be x%. Humean Supervenience (HS) claims that, among possible worlds like ours, no two differ without differing in the spacetime-point-by-spacetime-point arrangement of local properties. David Lewis (1986b, 1994a) has argued that PP contradicts HS, and the validity of his argument has been endorsed by Bigelow et al. (1993), Thau (1994), Hall (...) (1994), Strevens (1995), Ismael (1996), Hoefer (1997), and Black (1998). Against this consensus, I argue that PP might not contradict HS: Lewis's argument is invalid, and every attempt – within a broad class of attempts – to amend the argument fails. (shrink)

Kadri Vihvelin, in "What time travelers cannot do" (Philos Stud 81: 315-330, 1996), argued that "no time traveler can kill the baby who in fact is her younger self, because (V1) "if someone would fail to do something, no matter how hard or how many times she tried, then she cannot do it", and (V2) if a time traveler tried to kill her baby self, she would always fail. Theodore Sider (Philos Stud 110: 115-138, 2002) criticized Vihvelin's argument, and Ira (...) Kiourti (Philos Stud 139: 343-352, 2008) criticized both Vihvelin's argument and Sider's critique. I present a critique of Vihvelin's argument different from both Sider's and Kiourti's critiques: I argue in a novel way that both V1 and V2 are false. Since Vihvelin's argument might be understood as providing a challenge to the possibility of time travel, if my critique succeeds then time travel survives such a challenge unscathed. (shrink)

David Lewis (1980) proposed the Principal Principle (PP) and a “reformulation” which later on he called ‘OP’ (Old Principle). Reacting to his belief that these principles run into trouble, Lewis (1994) concluded that they should be replaced with the New Principle (NP). This conclusion left Lewis uneasy, because he thought that an inverse form of NP is “quite messy”, whereas an inverse form of OP, namely the simple and intuitive PP, is “the key to our concept of chance”. I argue (...) that, even if OP should be discarded, PP need not be. Moreover, far from being messy, an inverse form of NP is a simple and intuitive Conditional Principle (CP). Finally, both PP and CP are special cases of a General Principle (GP); it follows that so are PP and NP, which are thus compatible rather than competing. (shrink)

My main aim in this paper is to clarify the concepts of referential success and of referential continuity that are so crucial to the scientific realism debate. I start by considering the three dominant theories of reference and the intuitions that motivate each of them. Since several intuitions cited in support of one theory conflict with intuitions cited in support of another something has to give way. The traditional policy has been to reject all intuitions that clash with a chosen (...) theory. A more radical policy, tied to some experimental philosophers, has called for the rejection of any evidential role for intuitions. I explore a largely ignored third alternative, i.e. saving intuitions (and their evidential role) even when they are at odds. To accommodate conflicting intuitions different sets of internally consistent (yet externally inconsistent) intuitions are taken to lend credence to different concepts of reference. In the current context, this means that the concepts of referential success and referential continuity are not monolithic. They are what I call 'polylithic'. This paper is as much about meta-philosophical concerns with the role of intuitions as it is about reference and the scientific realism debate. Regarding the former I hope that a blueprint will emerge for similar projects in other philosophical domains. Regarding the latter, I hope that polylithicity helps disentangle claims about referential success and continuity in the scientific realism debate by making perspicuous which concepts are best equipped to evaluate the realist's epistemic claims against the historical record of science.

In this paper, I want to hold, first, that a treatment of Frege cases in terms of a difference in cognitive phenomenology of the involved experiential mental states is not viable. Second, I will put forward another treatment of such cases that appeals to a difference in intentional objects metaphysically conceived not as exotica, but as schematic objects, that is, as objects that have no metaphysical nature qua objects of thought. This allows their nature to be settled independently of their (...) being thought of, in particular as concrete entities in the sense of entities that may be spatiotemporal occupiers. Yet third, as to Frege cases, cognitive phenomenology may return from the back door. For the realization that, if correct, solves any such case cannot but have a proprietary, though neither distinctive nor individuative, phenomenology. In my account, this is the realization that the different schematic intentional objects involved are none other than the same entity. (shrink)

Recently, various people have maintained that one must revise either the externalistically-based notion of singular thought or the naïve realism-inspired notion of relational particularity, as respectively applied to some thoughts and to some perceptual experiences. In order to do so, one must either provide a broader notion of singular thought or flank the notion of relational particularity with a broader notion of phenomenal particularity. I want to hold that there is no need of that revision. For the original notions can (...) still play the role for which they were invoked. This requires that (i) both the first and the second notion respectively involve a dependence on and a metaphysical relation to the intentional objects of certain mental states once we are ontologically committed to such objects; (ii) both that object-dependence and that metaphysical relation are interpreted in terms of a substantive individuation of the relevant mental state via the object it is about: that object constitutes the state.

In the philosophy of fiction, a majority view is continuism, i.e., the thesis that ordinary names, or genuine singular terms in general, directly refer to ordinary real individuals in fiction-involving sentences – e.g. “Napoleon” in the sentences that constitute the text of Tolstoy’s War and Peace. But there is also a minority view, exceptionalism, which is the thesis that such terms change their semantic value in such sentences, either by directly referring to fictional surrogates of those individuals – what we (...) may call exceptional hyperrealism about fictional characters – or by acquiring a semantic value that turns them into nonreferential terms, involving no ontological commitment to such characters – exceptional irrealism about fictional characters. In this paper, first of all, I want to support hybrid exceptionalism, according to which both parties are partly right and partly wrong. In the fictional use of fiction-involving sentences, those terms directly refer to ordinary real individuals, as continuists claim, while both in the internal and the external metafictional use of fiction-involving sentences, such terms change their semantic value, as exceptionalists claim. (By contrast, for pure exceptionalists such terms either always refer to fictional surrogates or are nonreferring on all such uses.) Moreover, I will argue that hybrid exceptional hyperrealism must be preferred to hybrid exceptional irrealism: in the latter uses, I claim, such terms directly refer to fictional surrogates.

In the old days of descriptivism, fictional reference and non-fictional reference with proper names were treated on a par. Descriptivism was not an intuitive theory, but it meritoriously provided a unitary semantic account of names, whether referentially full or empty. Then the revolution of the new theory of reference occurred. This new theory is definitely more intuitive than descriptivism, yet it comes with a drawback: the referentially full use and the referentially empty use, notably the fictional use, of names are (...) semantically no longer on the same footing. How the use of names from fiction is referentially empty has even been seen as a symptom of its not being a use at all. In this paper, I ask the following question: can one keep the merits of the new theory of reference and still provide a unitary account of both fictional and non-fictional reference with names? My answer is positive, provided that one conceives proper names as a special kind of indexicals. (shrink)

In his (2001a) and in some related papers, Tim Crane has maintained that intentional objects are schematic entities, in the sense that, insofar as being an intentional object is not a genuine metaphysical category, qua objects of thought intentional objects have no particular nature. This approach to intentionalia is the metaphysical counterpart of the later Husserl's ontological approach to the same entities, according to which qua objects of thought intentionalia are indifferent to existence. But to buy a metaphysically deflationary approach (...) does not mean to buy an ontologically deflationary approach, according to which we have to accept all the intentional objects there apparently are. Being metaphysically deflationary on intentionalia rather means that from the ontological point of view one must really allow only for those intentionalia for which one is entitled to say that there are such things; typically, for which an ontological proof is available. From metaphysical schematism plus conditional, or partial, ontological committment to intentionalia, further interesting consequences follow. First, this theoretical combination allows one to deal with the ‘too-many entities’ problem (may one fail to accept an ontological proof for an entity of a given kind if she thinks that the entity we would have to be committed to is an entity of another kind?). Second, it allows one to deal with the ‘genuinely true report’ problem (how is it that if we exercise mindreading with respect to a somehow deluded person, we want our reports to come out as really, not merely fictionally, true?). (shrink)

There are two interpretations of what it means for a singular term to be referentially direct, one truth-conditional and the other cognitive. It has been argued that on the former interpretation, both proper names and indexicals refer directly, whereas on the latter only proper names are directly referential. However, these interpretations in fact apply to the same singular terms. This paper argues that, if conceived in purely normative terms, the linguistic meaning of indexicals can no longer be held to make (...) these terms referentially indirect under the second interpretation. This result is then generalized to proper names, by ascribing them a normative meaning as well. (shrink)

Abstract. Contrary to proposals that seek a harmonious integration of “science and religion” or “science and spirituality,” I argue that contemporary scientific and philosophical work at the mind-brain interface gives us reason to be skeptical of many of the claims found within religious spiritualities. Religious spiritualities typically presume commitment to strong versions of metaphysical dualism, while contemporary mind science gives us every reason to think that the mind is the brain. If materialism is true, what becomes of spirituality? Materialism or (...) naturalism is widely understood to be an anti-religious position with corrosive effects on morality. I correct this impression, arguing that materialism offers a compelling account of moral objectivity and is fully compatible with an appreciation for many aspects of religion. I further suggest that nothing precludes dialogue and conversation between naturalists and religious believers. (shrink)

Modal agnosticism is the view that we must be agnostic about whether things could have turned out differently. I argue that claims about unrealised possibilities are not justified by our modal intuitions, nor are they justified by any of the means proposed by philosophers. It follows that we do not have merely metaphysical modal knowledge, and that we must adopt modal agnosticism.

Since Machery et al. _Cognition_ 92, B1-B12 ( 2004 ) attacked Kripke’s refutation of classical descriptivism, their experiment has been repeated several times, in its original version or in some revised ones, by theorists with contrasting intents. Some repeated the experiment for confirming its results, others for proving them unreliable. One striking characteristic of those surveys is that they mostly replicated the data collected in Machery et al.’s _Cognition_ 92, B1-B12, 2004 experiment: less than 60% of Westerners showed preference for (...) the causal-historical response. We side with the critics of Machery et al.’s experiment. In this paper, we present the results of a survey that tests some hypotheses for explaining that percentage of Westerners’ preferences without taking it as evidence that more than 40% of Westerners have descriptivist intuitions on semantic reference. The aim of our paper is not merely to question the reliability of Machery et al.’s experiment. In sections 4 and 5 we assess the impact of our survey on the current debate in experimental semantics. We provide a novel account of the nature of the epistemic ambiguity that affects experiments in theory of reference and explain the consequences that our account of the epistemic ambiguity has for subsequent works trying to avoid ambiguities.

Ian Hacking uses the looping effect to describe how classificatory practices in the human sciences interact with the classified people. While arguably this interaction renders the affected human kinds unstable and hence different from natural kinds, realists argue that also some prototypical natural kinds are interactive and human kinds in general are stable enough to support explanations and predictions. I defend a more fine-grained realist interpretation of interactive human kinds by arguing for an explanatory domain account of the looping effect. (...) First, I argue that knowledge of the feedback mechanisms that mediate the looping effect can supplement, and help to identify, the applicability domain over which a kind and its property variations are stably explainable. Second, by applying this account to cross-cultural case studies of psychiatric disorders, I distinguish between congruent feedback mechanisms that explain matches between classifications and kinds, and incongruent feedback mechanisms that explain mismatches. For example, congruent mechanisms maintain Western auditory experiences in schizophrenia, whereas exporting diagnostic labels inflicts incongruence by influencing local experiences. Knowledge of the mechanisms can strengthen explanatory domains, and thereby facilitate classificatory adjustments and possible interventions on psychiatric disorders. (shrink)

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)

The phenomenal properties of conscious mental states happen to be exclusively accessible from the first-person perspective. Consequently, some philosophers consider their existence to be incompatible with materialist metaphysics. In this paper I criticise one particular argument that is based on the idea that for something to be real it must (at least in principle) be accessible from an intersubjective perspective. I argue that the exclusively subjective access to phenomenal contents can be explained by the very particular nature of the epistemological (...) relation holding between a subject and his own mental states. Accordingly, this subjectivity does not compel us to deny the possibility that phenomenal contents are ontologically objective properties. First, I present the general form of the argument that I will discuss. Second, I show that this argument makes use of a criterion of reality that is not applicable to the case of subjective experience. Third, I discuss a plausible objection and give an argument for rejecting observation models of self-knowledge of phenomenal contents. These models fall prey to the homunculus illusion. (shrink)

This article is a critical review of Cocchiarella’s theory of reference. In conceptual realism, there are two central distinctions regarding reference: first, between active and deactivated use of referential expressions, and, second, between using referential expressions with and without existential presupposition. Cocchiarella’s normative restrictions on the existential presuppositions of reference lead to postulating two fundamentally different kinds of objects in conceptual realism: realia or concrete objects, on the one hand, and abstract intensional objects or nonexistents, on the other. According to (...) Cocchiarella, nonexistents can be referred to only without existential presuppositions. However, referring to nonexistents with existential presuppositions is an ordinary human practice. To account for this fact, Cocchiarella’s normative theory of reference should be supplemented by a descriptive account of referring. (shrink)

The dynamics of general relativity is encoded in a set of ten differential equations, the so-called Einstein field equations. It is usually believed that Einstein's equations represent a physical law describing the coupling of spacetime with material fields. However, just six of these equations actually describe the coupling mechanism: the remaining four represent a set of differential relations known as Bianchi identities. The paper discusses the physical role that the Bianchi identities play in general relativity, and investigates whether these identities (...) --qua part of a physical law-- highlight some kind of a posteriori necessity in a Kripkean sense. The inquiry shows that general relativistic physics has an interesting bearing on the debate about the metaphysics of the laws of nature. (shrink)

This paper aims to contribute to debates about the nature of philosophical inquiry and its relation to science. The starting point is the Discontinuity View (DV), which holds that philosophy is discontinuous with science. Upon critically engaging two lines of argument in favor of DV, the paper presents and defends the Continuity View (CV), according to which philosophy and science are continuous forms of inquiry. The critical engagement sheds light on continuities between philosophical and scientific inquiry while underlining special normative (...) competences of philosophical work. The final part of the paper uses these insights to offer a brief outline of a normative approach to philosophy of science. (shrink)

It is common lore that standard, Kripke-style semantics for quantified modal logic is incompatible with the view that no individual may belong to more than one possible world, a view that seems to require a counterpart-theoretic semantics instead. Strictly speaking, however, this thought is wrong-headed. This note explains why.

Standard lore has it that a proper name is a temporally rigid designator. It picks out the same entity at every time at which it picks out an entity at all. If the entity in question is an enduring continuant then we know what this means, though we are also stuck with a host of metaphysical puzzles concerning endurance itself. If the entity in question is a perdurant then the rigidity claim is trivial, though one is left wondering how it (...) is that different speakers ever manage to pick out one and the same entity when a host of suitable, overlapping candidates are available. But what if the entity in question is neither a continuant nor a perdurant? What if the things we talk about in ordinary language are time-bound entities that cannot truly be said to persist through time, or stage sequences whose unity resides exclusively in our minds--like the “waves” at the stadium or the characters of a cartoon? In such cases the rigidity claim can’t be right and a counterpart-theoretic semantics seems required. Is that bad? I say it isn’t. And it had better not be, if that turns out to be the best metaphysical option we have. (shrink)

We tend to talk about (refer to, quantify over) parts in the same way in which we talk about whole objects. Yet a part is not something to be included in an inventory of the world over and above the whole to which it belongs, and a whole is not something to be included in the inventory over and above its constituent parts. This paper is an attempt to clarify a way of dealing with this tension which may be labeled (...) the Minimalist View: An element in the field of a part-whole relation is to be included in an inventory of the world if and only if it does not overlap any distinct element that is itself included in the inventory.

En este trabajo examino el argumento de McFetridge a favor de la necesidad de la creencia en la necesidad. El argumento pretende establecer un dilema fatal para el “nihilista” modal, aquel que no cree que al menos alguna proposición es necesaria. Mi objetivo principal es mostrar que el dilema que presenta el argumento de McFetridge no es sólido, pues tiene una limitación muy importante con respecto al segundo de sus cuernos, el cual es el más interesante. El segundo cuerno del (...) dilema plantea una especie de argumento trascendental: es necesario creer en la necesidad si es que vamos a ser capaces de razonar confiablemente bajo suposiciones contrafácticas. Sin embargo, este argumento asume que la suposición contrafáctica es una actividad esencial en nuestras vidas, lo cual señala, sostengo, un punto central alrededor del cual el nihilista modal intentaría reafirmar su posición. Así, pretendo mostrar que el segundo cuerno del dilema de McFetridge revela que el quid de la discusión entre creyentes y nihilistas modales debe moverse propiamente de la cuestión del rol de la creencia en la necesidad a la cuestión del rol de la suposición contrafáctica.

Quine ha promovido una forma de escepticismo sobre los juicios de modalidad de re que cuestiona su función y sugiere, en consecuencia, su eliminación. Wiggins, por su parte, ha argumentado que nuestros juicios ordinarios de individuación de objetos nos comprometen con un cierto esencialismo, con la aceptación de ciertos juicios de modalidad de re. Si Wiggins tuviera razón, tendríamos una respuesta potencial al escepticismo quineano de la función. Sin embargo, en este trabajo argumento que la propuesta de Wiggins es incapaz (...) de proporcionar una respuesta satisfactoria al escepticismo quineano, pues presupone aquello mismo que está en cuestión: los compromisos esencialistas se siguen sólo de la adopción previa de otros juicios de modalidad de re cuya función está precisamente en entredicho. Asimismo, argumento que esta misma conclusión puede extraerse de la consideración de algunas otras teorías contemporáneas de la individuación, similares a la de Wiggins. (shrink)

David Lewis’s counterpart theory is often seen as involving a radical departure from the standard, Kripke-style semantics for modal logic, suggesting that we are dealing with deeply divergent accounts of our modal talk. However, CT captures but one version of the relevant semantic intuition, and does so on the basis of metaphysical assumptions that are ostensibly discretionary. Just as ML can be translated into a language that quantifies explicitly over worlds, CT may be formulated as a semantic theory in which (...) world quantification is purely metalinguistic. And just as Kripke-style semantics is formally compatible with the doctrine of world-boundedness, a counterpart-based semantics may in principle allow for cases of trans-world identity. In fact, one may welcome a framework that is general enough to include both Lewis’s counterpart-based account and Kripke’s identity-based account as distinguished special cases. There are several ways of doing so. The purpose of this paper is to outline a fully general option and to illustrate its philosophical significance, showing how the large variety of intermediate relations that lie between Lewisian counterparthood and Kripkean identity yield a corresponding variety of modal theories that would otherwise remain uncharted.
