Using web standards, such as uniform resource identifiers (URIs), XML and HTTP, for naming and describing resources which are not information objects is the key difference between the Web as we know it today and the Semantic Web. Naming and interlinking this type of resources by HTTP URIs (instead of individual constants in a formal language) is the key feature which distinguishes traditional knowledge representation from web-scale knowledge representation. However, this use of URIs brought back attention to the old philosophical (...) problem of identity and reference in a new form. In this paper, we analyze the new version of the problem, provide a formal model for dealing with it when interlinking knowledge on the Web, and argue for the need of a distinction between the use of URIs for describing and accessing resources, and the use of URIs for fixing the reference . We show that in the current practice of linking data these roles are not clearly distinguished, and that this fact may cause unwanted effects and prevent some basic forms of data integration. We also discuss the role of an entity name system as a potential piece of infrastructure for fixing the reference in the Semantic Web. (shrink)

This paper advances a version of physicalism which reconciles the “a priori entailment thesis” (APET) with the analytic independence of our phenomenal and physical vocabularies. The APET is the claim that, if physicalism is true, the complete truths of physics imply every other truth a priori. If so, “cosmic hermeneutics” is possible: a demon having only complete knowledge of physics could deduce every truth about the world. Analytic independence is a popular physicalist explanation for the apparent “epistemic gaps” between phenomenal (...) and physical truths. The two are generally seen as incompatible, since the demon’s deductions seem to presuppose analytic connections between physical and phenomenal terms. I begin by arguing, in support of the APET, that implications from the complete truths of physics to phenomenal truths cannot be a posteriori. Such implications are (according to the physicalist) necessarily true. But they cannot be Kripke-style a posteriori necessities, since (according to the physicalist) the complete truths of physics fix any relevant a posteriori facts about the reference of terms. I then show how the physicalist can turn the tables: the demon can exploit the physical fixing of reference to bridge the gap between the vocabularies, by deducing when phenomenal and physical terms co-refer. This opens the way for a “type-C” physicalism, which accepts in-principle deducibility while still appealing to analytic independence to explain why we (who are not demons) find it impossible to see phenomenal-physical connections a priori.

This paper divides the sophisms and paradoxes put forth by Chinese thinkers of the pre-Qin period of China into six groups: paradoxes of motion and infinity, paradoxes of class membership, semantic paradoxes, epistemic paradoxes, paradoxes of relativization, other logical contradictions. It focuses on the comparison between the Chinese items and the counterparts of ancient Greek and even of contemporary Western philosophy, and concludes that there turn out to be many similar elements of philosophy and logic at the beginnings of Chinese (...) and Greek civilizations.

The paper shows – contra what has been argued by Trenton Merricks – that counterpart theory, when conjoined with composition as identity, does not entail mereological essentialism. What Merrick’s argument overlooks is that contingent identity is but one of the effects of grounding identity across possible worlds on similarity.

Kripke complained that counterpart theory makes modal claims be about counterparts and not about us, and that it is a misguided model of modality since we do not care about counterparts in the same way we care about ourselves. The first part of the complaint, I argue, has been met by Hazen and Lewis, while the second can be countered by observing that most of our modal concerns are about role‐fillers and that counterparts are well‐suited to such concerns. The role‐filler (...) analysis of modal concerns, however, does not seem to capture certain attitudes ‐ especially that of regret. Regret, however, I will argue, is not intrinsically modal and thus is no challenge to my general analysis of modal concerns. (shrink)

After a brief review of the notions of necessity and a priority, this paper scrutinizes Kripke's arguments for supposedly contingent a priori propositions and necessary a posteriori propositions involving proper names, and reaches a negative conclusion, i.e. there are no such propositions, or at least the propositions Kripke gives as examples are not such propositions. All of us, including Kripke himself, still have to face the old question raised by Hume, i.e. how can we justify the necessity and universality of (...) general statements on the basis of sensory or empirical evidence?

Scientific writings and policy documents define the terms nanomaterial and nanoparticle in various ways. This variation is considered problematic because the absence of a shared definition is understood as potentially hindering nanomaterial knowledge production and regulation. Another view is that the existence of a shared definition may itself cause problems, as rigid definitions arguably exclude important aspects of the studied phenomena. The aim of this paper is to inform this state of disagreement by providing analytical concepts for a systematic understanding (...) of how, and even whether, nanomaterial and nanoparticle could and should be defined. To do this, we review definitions of nanomaterial and nanoparticle presented in research articles and policy documents. Definitions were identified by first conducting a Scopus search and then tracing cited definitions back to their sources. In total, 36 definitions were identified. Theories of definition from philosophy and linguistics provide analytical guidance for structuring and categorizing the identified definitions, and the main analytical dimensions of the definitions are then identified and discussed. Finally, we propose a framework for understanding the process of defining nanomaterial and nanoparticle. This framework considers both the generality needed for a shared understanding and the level of precision required for different purposes. (shrink)

In the standard thought experiments, dualism strikes many philosophers as true, including many non-dualists. This ‘striking’ generates prima facie justification: in the absence of defeaters, we ought to believe that things are as they seem to be, i.e. we ought to be dualists. In this paper, I examine several proposed undercutting defeaters for our dualist intuitions. I argue that each proposal fails, since each rests on a false assumption, or requires empirical evidence that it lacks, or overgenerates defeaters. By the (...) end, our prima facie justification for dualism remains undefeated. I close with one objection concerning the dialectical role of rebutting defeaters, and I argue that the prospects for a successful rebutting defeater for our dualist intuitions are dim. Since dualism emerges undefeated, we ought to believe it. (shrink)

Herman Cappelen (2012) has written a book that's devoted to arguing against the following claim: Centrality (of Intuitions in Contemporary Philosophy): Contemporary analytic philosophers rely on intuitions as evidence (or as a source of evidence) for philosophical theories. In arguing against Centrality, Cappelen is not making a normative claim: that although philosophers rely on intuitions, they ought not to. He's not making a metaphysical claim to the effect that there are no intuitions, hence none that philosophers can rely on to (...) justify their claims.... (shrink)

Robert Stalnaker contrasts two interpretations, semantic and metasemantic, of the two-dimensionalist framework. On the semantic interpretation, the primary intension or diagonal proposition associated with an utterance is a semantic value that the utterance has in virtue of the actual linguistic meaning of the corresponding sentence, and that primary intension is both what a competent speaker grasps and what determines different secondary intensions or horizontal propositions relative to different possible worlds considered as actual. The metasemantic interpretation reverses the order of explanation: (...) an utterance has the primary intension it has because it yields the secondary intensions it yields relative to different possible worlds considered as actual. In these possible worlds, the semantic facts can be different: the metasemantic interpretation is metasemantic in the sense that the secondary intensions are determined relative to possible worlds considered as actual given the meanings the expressions have there. Stalnaker holds a causal picture of the reference of names, according to which names have no meaning over and above their unique referent, and therefore maintains that the semantic interpretation is not an option. He thus endorses the metasemantic interpretation, while insisting that this interpretation does not, contrary to what he originally thought, yield any account of a priori truth and knowledge. My double aim in this paper is to show (i) that the metasemantic interpretation, as sketched by Stalnaker, is not compatible with one natural understanding of the causal picture of reference, on which names are rigid because they have their original bearers essentially , and (ii) that a third kind of interpretation of the framework is available, the metasyntactic interpretation, which grants that names have their bearers essentially and yields some account of a priori knowledge.

The canonical arguments against the description theory of names are usually taken to have established that the reference of a name as used on a given occasion is not semantically determined by the qualitative descriptions that the speaker may have in mind. The deepest moral of these arguments, on the received view, would be that the speaker’s narrow mental states play no semantic role in fixing reference. My central aim in this paper is to challenge this common understanding by highlighting (...) that the same argumentative schemas can be adapted to undermine a related non-description theory, according to which the reference of a name as used on a given occasion would semantically depend on broad mental states of the speaker. Once this is realised, it becomes evident that the falsity of the description theory is not the deepest lesson of the canonical arguments, but only a consequence of the deepest lesson. The most fundamental moral is that the speaker’s mental states, whether narrow or broad, do not always determine linguistic reference. (shrink)

Neofregeanism and structuralism are among the most promising recent approaches to the philosophy of mathematics. Yet both have serious costs. We develop a view, structuralist neologicism, which retains the central advantages of each while avoiding their more serious costs. The key to our approach is using arbitrary reference to explicate how mathematical terms, introduced by abstraction principles, refer. Focusing on numerical terms, this allows us to treat abstraction principles as implicit definitions determining all properties of the numbers, achieving a key (...) neofregean advantage, while preserving the key structuralist advantage, which objects play the number role does not matter.

This article systematically challenges Kripke's modal argument and Soames's defence of this argument by arguing that, just like descriptions, names can take narrow or wide scopes over modalities, and that there is a big difference between the wide scope reading and the narrow scope reading of a modal sentence with a name. Its final conclusions are that all of Kripke's and Soames's arguments are untenable due to some fallacies or mistakes; names are not “rigid designators”; if there were rigid designators, (...) description(s) could be rigidified to refer fixedly to objects; so names cannot be distinguished in this way from the corresponding descriptions. A descriptivist account of names is still correct; and there is no justification for Kripke's theory of rigid designation and its consequences. (shrink)

This paper argues for a possible worlds theory of the content of pictures, with three complications: depictive content is centred, two-dimensional and structured. The paper argues that this theory supports a strong analogy between depictive and other kinds of representation and the platitude that depiction is mediated by resemblance.

The possibilities of depicting non-existents, depicting non-particulars and depictive misrepresentation are frequently cited as grounds for denying the platitude that depiction is mediated by resemblance. I first argue that these problems are really a manifestation of the more general problem of intentionality. I then show how there is a plausible solution to the general problem of intentionality which is consonant with the platitude.

We evaluate the scope of Jaegwon Kim's “supervenience argument” for reduction. Does its conclusion apply only to psychology, or does it generalize to all the special sciences? The claim that the supervenience argument generalizes to all the special sciences if it goes through for psychology is often raised as an objection to the supervenience argument. We argue that this objection is ambiguous. We distinguish three readings of it and suggest that some of them make it a plausible claim, whereas other (...) readings make it implausible. We suggest that this ambiguity is the result of picturing the world as being hierarchically organized in levels, with the domain of physics at the bottom and the domains of the social sciences at the top. The plausibility of the objection depends on how we think of this picture. This popular picture, we suggest, involves three different dimensions along which reduction may occur. (shrink)

Legal philosophers share the same phenomenology of legal practice. Yet, they differ in its explanation. For normativists, descriptivists got it wrong and vice versa. This controversy between normativists and descriptivists will be called “the methodological problem” in legal theory. Normativists such as Dworkin and Perry argue that descriptivists need evaluation. By contrast, descriptivists such as Coleman argue that normativists need the methods of descriptivism such as conceptual analysis and therefore might be committed to descriptivism. The paper shows that the responses (...) of Perry and Coleman to the methodological problem are not free from difficulties. The article also advances a reinterpretation of normativism in terms of two tenets: 1. the semantic sting argument, and 2. the ametaphysical thesis argument. If the latter argument is sound, normativism is unavoidable, because if there cannot be an external point of view or Archimedean perspective, then we can only resort to our moral convictions or substantive claims. The first tenet has been criticized in previous work and the paper focuses on a criticism of the second tenet. (shrink)

I exploit parallel considerations in the philosophy of mind and metaethics to argue that the reasoning employed in an important argument for panpsychism overgeneralizes to support an analogous position in metaethics: panmoralism. Next, I raise a number of problems for panmoralism and thereby build a case for taking the metaethical parallel to be a reductio ad absurdum of the argument for panpsychism. Finally, I contrast panmoralism with a position recently defended by Einar Duenger Bohn and argue that the two suffer (...) from similar problems. I conclude by drawing some general lessons for panpsychism. (shrink)

Contemporary hybrid logic is based on the idea of using formulas as terms, an idea invented and explored by Arthur Prior in the mid-1960s. But Prior’s own work on hybrid logic remains largely undiscussed. This is unfortunate, since hybridisation played a role that was both central to and problematic for his philosophical views on tense. In this paper I introduce hybrid logic from a contemporary perspective, and then examine the role it played in Prior’s work.

Standard motivational internalism is the claim that by a priori or conceptual necessity, a psychological state is a moral opinion only if it is suitably related to moral motivation. Many philosophers, the authors of this paper included, have assumed that this claim is supported by intuitions to the effect that amoralists—people not suitably related to such motivation—lack moral opinions proper. In this paper we argue that this assumption is mistaken, seeming plausible only because defenders of standard internalism have failed to (...) consider the possibility that our own actual moral practice as a whole is one where moral opinions fail to motivate in the relevant way. To show this, we present a cynical hypothesis according to which the tendency for people to act in accordance with their moral opinions ultimately stems from a desire to appear moral. This hypothesis is most likely false, but we argue, on both intuitive and methodological grounds, that it is conceptually possible that it correctly describes our actual moral opinions. If correct, this refutes standard motivational internalism. Further, we propose an explanation of why many have seemingly internalist intuitions. Such intuitions, we argue, stem from the fact that standard amoralist cases allow (or even suggest) that we apprehend the putative moral opinions of amoralists as radically different from how we understand actual paradigmatic moral opinions. Given this, it is reasonable to understand them as not being moral opinions proper. However, since these intuitions rest on substantial a posteriori assumptions about actual moral opinions, they provide no substantial a priori constraints on theories of moral judgment. (shrink)

A number of important legal theorists have recently argued for metaphysically realist approaches to legal determinacy grounded in particular semantic theories or theories of reference, in particular, views of meaning and reference based on the works of Putnam and Kripke. The basic position of these theorists is that questions of legal interpretation and legal determinacy should be approached through semantic meaning. However, the role of authority (in the form of lawmaker choice) in law in general, and democratic systems in particular, (...) require that these realist solutions to the problem of legal determinacy be rejected, or at least significantly revised.

What factors are involved in the resolution of scientific disputes? What factors make the resolution of such disputes rational? The traditional view confers an important role on observation statements that are shared by proponents of competing theories. Rival theories make incompatible (sometimes contradictory) observational predictions about a particular situation, and the prediction made by one theory is borne out while the prediction made by the other is not. Paul Feyerabend, Thomas Kuhn, and Paul Churchland have called into question this account (...) of theory-resolution. According to these philosophers, substantially different and competing scientific theories are semantically incommensurable: those theories do not share a common observation language. Two charges have been leveled against the semantic incommensurability theories. The first is that it ignores that some semantic features of observational terms (e.g., their reference) can be expressed by proponents of competing theories. The second is that the semantic incommensurability thesis is self-defeating. In this paper I will argue that both of these charges are true but not for the reasons usually given. (shrink)

Scientific realism says of our best scientific theories that (1) most of their important posits exist and (2) most of their central claims are approximately true. Antirealists sometimes offer the pessimistic induction in reply: since (1) and (2) are false about past successful theories, they are probably false about our own best theories too. The contemporary debate about this argument has turned (and become stuck) on the question, Do the central terms of successful scientific theories refer? For example, Larry Laudan (...) offers a list of successful theories that employed central terms that failed to refer, and Philip Kitcher replies with a view about reference in which the central terms of such theories did sometimes refer. This article attempts to break this stalemate by proposing a direct version of the pessimistic induction, one that makes no explicit appeal to a substantive notion or theory of reference. While it is premature to say that this argument succeeds in showing that realism is probably false, the direct pessimistic induction is not subject to any kind of reference-based objection that might cripple a weaker, indirect version of the argument. Any attempt to trounce the direct pessimistic induction with a theory of reference fails. (shrink)

In this paper I argue that it is not a priori that all the laws of nature are contingent. I assume that the fundamental laws are contingent and show that some non-trivial, a posteriori, non-basic laws may nonetheless be necessary in the sense of having no counterinstances in any possible world. I consider a law LS (such as 'salt dissolves in water') that concerns a substance S. Kripke's arguments concerning constitution show that the existence of S requires that a certain (...) deeper level law or variants thereof hold. At the same time, that law and its variants may each entail the truth of LS. Thus the existence of S entails LS. Consequently there is no world in which S exists and fails to obey LS. I consider the conditions concerning the fundamental laws that would make this phenomenon ubiquitous. I conclude with some consequences for metaphysics. (shrink)

This paper maps the landscape for a range of views concerning the metaphysics of natural kinds. I consider a range of increasingly ontologically committed views concerning natural kinds and the possible arguments for them. I then ask how these relate to natural kind essentialism, arguing that essentialism requires commitment to kinds as entities. I conclude by examining the homeostatic property cluster view of kinds in the light of the general understanding of kinds developed.

This paper sketches a dispositionalist conception of laws and shows how the dispositionalist should respond to certain objections. The view that properties are essentially dispositional is able to provide an account of laws that avoids the problems that face the two views of laws (the regularity and the contingent nomic necessitation views) that regard properties as categorical and laws as contingent. I discuss and reject the objections that (i) this view makes laws necessary whereas they are contingent; (ii) this view (...) cannot account for certain kinds of laws of nature and their properties.

Why, despite his enormous influence in the latter part of the twentieth century, has Kuhn left no distinctively Kuhnian legacy? I argue that this is because the development of Kuhn’s own thought was in a direction opposite to that of the mainstream of the philosophy of science. In the 1970s and 1980s the philosophy of science took on board the lessons of externalism as regards reference and knowledge, and became more sympathetic to a naturalistic approach to philosophical problems. Kuhn, on (...) the other hand, started out with a strong naturalistic streak, employing non-philosophical disciplines, primarily psychology, in order to build his accounts of scientific change and the nature of observation and scientific thought. But by the 1970s Kuhn’s work had taken on a much more purely philosophical, a priori, tone. His explanation of incommensurability moved from a psychological explanation to one embedded in the philosophy of language. Increasingly he gave his outlook a Kantian gloss. I suggest, nonetheless, that Kuhn’s most valuable contribution is to be found in The Structure of Scientific Revolutions and not in his later work, and that the naturalistic direction of the former has important links with connectionist research in cognitive science that deserve further study.Author Keywords: Kuhn; Scientific revolutions; Empiricism; Naturalism; Incommensurability; Reference.

Those who favour an ontology based on dispositions are thereby able to provide a dispositional essentialist account of the laws of nature. In part 1 of this paper I sketch the dispositional essentialist conception of properties and the concomitant account of laws. In part 2, I characterise various claims about the modal character of properties that fall under the heading ‘quidditism’ and which are consequences of the categoricalist view of properties, which is the alternative to the dispositional essentialist view. I (...) argue that quidditism should be rejected. In part 3, I address a criticism of a strong dispositional essentialist view, viz. that ‘structural’ (i.e. geometrical, numerical, spatial and temporal) properties must be regarded as categorical.

The article attempts to show some limitations to reductive accounts in science and philosophy of body-mind relations, experience and skill. Extensive literature has developed in analytic philosophy of mind recently due to new technology and theories in the neurosciences. In the sporting sciences, there are also attempts to reduce experiences and skills to biology, mechanics, chemistry and physiology. The article argues there are three fundamental problems for reductive accounts that lead to an explanatory gap between the reduction and the conscious (...) experience. First, reductive accounts deal with objective observations; conscious experiences are subjective. Second, subjective experience seems difficult to identify with physical events described by chemistry, biology, mechanics or neurophysiology. Finally, sport involves knowing how and knowing how is also difficult to reduce to propositional knowledge, which is the reductive scientific/philosophical project. The article argues that sport provides an excellent platform to better understand what is wrong with reductive analysis in body-mind relations, since both conscious experience and knowing how are fundamental to sport performance.

Descartes was certain that he was thinking and he was accordingly certain that he existed. Like Descartes, we seem to be more certain of our thoughts and our existence than of anything else. What is less clear is the reason why we are thus certain. Philosophers throughout history have provided different interpretations of the cogito, disagreeing both on the kind of thoughts it characterizes and on the reasons for its cogency. According to what we may call the empiricist interpretation of (...) the cogito, I can only claim to be certain of having experiences, and this certainty, as well as that of my own existence, stems from their phenomenal and subjective character. According to rationalist interpretations, on the other hand, I am certain of having some self-reflexive propositional attitudes, and this certainty derives from their rational features. Psychiatric patients suffering from acute forms of depersonalization or of the Cotard syndrome often doubt that they think and exist, and might even believe that they don't. I argue that their study allows us to favor the empiricist interpretation of the cogito. (shrink)

This paper introduces a modal epistemology that centers on inference to the best explanation (i.e. abduction). In introducing this abduction-centered modal epistemology, the paper has two main goals. First, it seeks to provide reasons for pursuing an abduction-centered modal epistemology by showing that this epistemology aids a popular stance on the mind-body problem and allows an appealing approach to modality. Second, the paper seeks to show that an abduction-centered modal epistemology can work by showing that abduction can establish claims about (...) necessity/possibility (i.e. modal claims)—where ‘necessity’ and ‘possibility’ denote metaphysical necessity and possibility, ways things may or may not have been given how they actually are.

Famously, both Saul Kripke and Keith Donnellan opposed description theories and insisted on the role of history in determining the reference of a proper name token. No wonder, then, that their views on proper names have often been assimilated. By focusing on reference borrowing—an alleged phenomenon that Kripke takes to be fundamental—we argue that they should not be. In particular, we claim that according to Donnellan a proper name token never borrows its reference from preceding tokens which it is historically (...) connected to. On the contrary, its reference is always fixed anew on who or what the speaker has in mind when he or she produces it. In fact, what is important to realize is that Donnellan and Kripke took two different histories to be relevant: that of the proper name token produced by the speaker , and that of the cognitive status of the speaker when he or she produces it . We end by suggesting that this difference between Kripke’s and Donnellan’s accounts of proper names rests on a more general difference in their approach to language. (shrink)

Everyone knows what David Lewis' possible worlds are, what role they play in his account of possibility and necessity, and Saul Kripke's criticisms. But what, instead, are Kripke's possible worlds, and what role do they play in his account of possibility and necessity? The answers are not so obvious. Recently, it has even been claimed that, contrary to what is standardly assumed, Kripke's approach to modality has not always been consistently metaphysical. In particular, an interpretation of the famous passage in (...) the preface to Naming and Necessity with Kripke's discussion of the dice example has been put forward, according to which he purports there to clarify the modal notions in terms of that of possible world, model-theoretically construed, in a way which is reminiscent of Carnap's. In this paper, I shall point out some internal difficulties of this interpretation, and offer a different one, according to which in the dice passage Kripke is trying, consistently with his metaphysical approach, to legitimize the technically useful notion of possible world starting from modal notions, to be accounted for in another way (arguably, in an essentialistic framework). My final goal, however, will be philosophical elucidation rather than mere exegesis. Indeed, I am interested in shedding some light on what possible worlds might possibly be, if something like Kripke's metaphysical approach is on the right track. (shrink)

Despite the currently perceived urgent need among contemporary philosophers of chemistry for adjudicating between two rival metaphysical conceptual frameworks—is chemistry primarily a science of substances or processes?—this essay argues that neither provides us with what we need in our attempts to explain and comprehend chemical operations and phenomena. First, I show the concept of a chemical property can survive the abandoning of the metaphysical framework of substance. While this abandonment means that we will need to give up essential properties, contingent (...) properties can give us all the stability we need to account for chemical continuity as well as change. I then go on to show that this attention to clusters of contingent properties does not force us into the arms of an alternative process metaphysical framework either. Finally, I sketch a view I call particularism with respect to chemical properties on analogy with moral particularism. I conclude by sketching some of the implications for the field of philosophy of chemistry of my proposal that we abandon our interest in the metaphysical question of what chemistry is primarily about in favor of a broadly scientific particularism with respect to kinds and properties.

I examine Reichenbach’s theory of relative a priori and Michael Friedman’s interpretation of it. I argue that Reichenbach’s view remains at bottom conventionalist and that one issue which separates Reichenbach’s account from Kant’s apriorism is the problem of mathematical applicability. I then discuss Hermann Weyl’s theory of blank forms which in many ways runs parallel to the theory of relative a priori. I argue that it is capable of dealing with the problem of applicability, but with a cost.

I outline a neo-Fregean strategy in the debate on the existence of possible worlds. The criterion of identity and the criterion of application are formulated. Special attention is paid to the fact that speakers do not possess proper names for worlds. A broadly Quinean solution is proposed in response to this difficulty.

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.

I discuss here the nature of nonconscious mental states and the ways in which they may differ from their conscious counterparts. I first survey reasons to think that mental states can and often do occur without being conscious. Then, insofar as the nature of nonconscious mentality depends on how we understand the nature of consciousness, I review some of the major theories of consciousness and explore what restrictions they may place on the kinds of states that can occur nonconsciously. I (...) close with a discussion of what makes a state mental, if consciousness is not the mark of the mental. (shrink)

Content externalism about memory says that the individuation of memory contents depends on relations the subject bears to his past environment. I defend externalism about memory by arguing that neither philosophical nor psychological considerations stand in the way of accepting the context dependency of memory that follows from externalism.

In his famous work on vagueness, Russell named “fallacy of verbalism” the fallacy that consists in mistaking the properties of words for the properties of things. In this paper, I examine two (clusters of) mainstream paraconsistent logical theories – the non-adjunctive and relevant approaches –, and show that, if they are given a strongly paraconsistent or dialetheic reading, the charge of committing the Russellian Fallacy can be raised against them in a sophisticated way, by appealing to the intuitive reading of (...) their underlying semantics. The meaning of “intuitive reading” is clarified by exploiting a well-established distinction between pure and applied semantics. If the proposed arguments go through, the dialetheist or strong paraconsistentist faces the following Dilemma: either she must withdraw her claim to have exhibited true contradictions in a metaphysically robust sense – therefore, inconsistent objects and/or states of affairs that make those contradictions true; or she has to give up realism on truth, and embrace some form of anti-realistic (idealistic, or broadly constructivist) metaphysics. Sticking to the second horn of the Dilemma, though, appears to be promising: it could lead to a collapse of the very distinction, commonly held in the literature, between a weak and a strong form of paraconsistency – and this could be a welcome result for a dialetheist.
