Debates on the metaphysics of science have steadily gained momentum over the last decade or so. This appears to illustrate a case of philosophers’ realisation that metaphysics—and theoretical philosophy overall—largely depends upon the sciences and has a good deal to learn from them. Recent literature on this, in fact, has reached an unforeseen high level of refinement in the arguments and a very much desirable precision in the consequences that we can derive from examining the interplay currently undergoing between science (...) and metaphysics. The editors of the volume under review have certainly done a great work by compiling some fruitful and novel contributions to our understanding of issues such as the aim and scope of the metaphysics of science, laws of nature, causation, and natural kinds, which are amongst the most heatedly discussed topics in the arena.The structure of the volume is as follows: “What is the metaphysics of science?” ; “Measurements, la ..

Is consciousness or the subject part of the natural world or the human world? Can we write intentionality, so central in Husserl's philosophy, into Quine's system of ontological naturalism and naturalized epistemology — or into Heidegger's account of human being and existential phenomenology? The present task is to show how to do so. Anomalous monism provides a key.

That expressions should have their contents can seem paradigmatically contingent. But it can also seem a priori that expressions in one's own language should have their contents to the extent that instances of disquotation, such as "Socrates" refers to Socrates' and "cat" refers to cats', are trivially true. I attempt to reconcile these conflicting intuitions about meaningfulness by examining semantic and metasemantic details of linguistic reflexivity. I argue that instances of disquotation are contingent analytic in Kaplan's sense, and bring this (...) lesson to bear on semantic strategies for responding to skepticism, such as Putnam's Brains-in-a-Vat argument.

Extensionalism, as I understand it here, is the view that physical reality consists exclusively of extensional entities. On this view, intensional entitities must either be eliminated in favor of an ontology of extensional entities, or be reduced to such an ontology, or otherwise be admitted as non-physical. In this paper I argue that extensionalism is a misguided philosophical doctrine. First, I argue that intensional phenomena are not confined to the realm of language and thought. Rather, the ontology of such phenomena (...) is intimately entwined with the ontology of properties. After providing some evidence to the popularity of extensionalism in contemporary analytic philosophy, I investigate the motivating reasons behind it. Considering several explanations, I argue that the main motivating reason is rooted in the identification of matter with extension, an identification which is one of the hallmarks of the mechanistic conception of nature inherited from the founding fathers of our modern scientific outlook. I then argue that such a conception is not only at odds with a robust ontology of properties but is also at odds with our best contemporary physics. Rather than vindicating extensionalism contemporary science undermines the position, and the lesson to be drawn from this surprising fact is that extensionalism needs no longer be espoused as a regulative ideal of naturalistic philosophy. I conclude by showing that the ontological approach to intensional phenomena advocated throughout the paper also gains support from an examination of the historical context within which ‘intension’ was first introduced as a semantic notion.

Many have bowed before the recently acquired powers of ‘new technologies’. However, in the shift from tekhnē to tekhnologia, it seems we have lost human values. These values are communicative in nature as technological progress has placed barriers like distance, web pages and ‘miscellaneous extras’ between individuals. Certain values, like the interpersonal pleasures of rendering service, have been lost as their domain of predilection has for many become fully commercially oriented, dominated by the cadence of profitability. Though the popular cultures (...) of the artificial have surged forth to deliver us from the twentieth century, they have enabled some very superfluous dreaming—Man has succumbed to the Godly role of simulating himself and creating other beings. Communication is replaced by machines, services are rendered via many automated devices, procreation has entered the public sphere, robots and entertainment agents educate our youth and mesmerising screen-integrating ‘forms of intelligence’ even think for us. As such, this so-called culture threatens the very values Man constructed in the nineteenth and twentieth centuries to guide himself into the future. But what if the phenomena mentioned just reflect our new values? The author presents an investigation into this cultural shift, its impact on human practices with regards the mind and the body and evokes some pros and cons of generally accepting the ‘Culture of the Artificial’.

Todd (2016) proposes an analysis of future-directed sentences, in particular sentences of the form 'will(φ)', that is based on the classic Russellian analysis of definite descriptions. Todd's analysis is supposed to vindicate the claim that the future is metaphysically open while retaining a simple Ockhamist semantics of future contingents and the principles of classical logic, i.e. bivalence and the law of excluded middle. Consequently, an open futurist can straightforwardly retain classical logic without appeal to supervaluations, determinacy operators, or any further (...) controversial semantical or metaphysical complication. In this paper, we will show that this quasi-Russellian analysis of 'will' both lacks linguistic motivation and faces a variety of significant problems. In particular, we show that the standard arguments for Russell's treatment of definite descriptions fail to apply to statements of the form 'will(φ)'. (shrink)

Patrick Suppes'' set-theoretical approach to the analysis of theories, and Joseph D. Sneed''s metatheory are briefly outlined. The notions of observation, illusion and hallucination are reconstructed according to these approaches. It is argued that the terms perception and truth are theoretical with respect to observation but nontheoretical with respect to illusion and hallucination. Hallucination is construed as a special kind of illusion.

: Philosophical naturalism is ambiguous between conjoining philosophy with science or with nature understood scientifically. Reconciliation of this ambiguity is necessary but rarely attempted. Feminist science studies often endorse the former naturalism but criticize the second. Karen Barad's agential realism, however, constructively reconciles both senses. Barad then challenges traditional metaphysical naturalisms as not adequately accountable to science. She also contributes distinctively to feminist reinterpretations of objectivity as agential responsibility, and of agency as embodied, worldly, and intra-active.

There is a long-standing debate in the philosophy of action and the philosophy of science over folk psychological explanations of human action: do the (perhaps implicit) generalizations that underwrite such explanations purport to state contingent, empirically established connections between beliefs, desires, and actions, or do such generalizations serve rather to define, at least in part, what it is to have a belief or desire, or perform an action? This question has proven important because of certain traditional assumptions made about the (...) role of law-statements in scientific explanations. According to this tradition, law-statements take the form of generalizations, and the laws we find in well-established sciences are contingent and empirical; as such, if the kinds of generalizations at work in folk psychological explanations of human action act like definitions, or state conceptual connections, then such generalizations could not play the kind of explanatory role we find in mature sciences. This paper argues that the aforementioned way of framing the debate reflects a still powerful but impoverished conception of the role laws play in scientific explanations, a conception that, moreover, cannot be reconciled with a good deal of actual scientific practice. When we update the philosophy of science, we find the concerns that are raised for folk psychological explanations largely evaporate or are found not to be specific to such explanations. (shrink)

The cognitive revolution in psychology was a significant advance in our thinking about the mind. Philosophers and social scientists have looked to the cognitive sciences with the hope that the social world will yield to similar explanatory strategies. Dan Sperber has argued for a programme that would conceptualize the entire domain of anthropological theory in cognitive terms. Sperber's 'epidemiology' specifically excludes interpretive, structuralist and functionalist theories. This essay evaluates Sperber's epidemiological approach to anthropological theory. It argues that as a programme (...) for anthropological theorizing, Sperber's epidemiology could not be empirically grounded. Cognitive explanations depend on prior interpretations. While interpretation is a kind of theorizing, it cannot be assimilated to cognitive explanation. The essay concludes by sketching an explanatory coherence framework in which ethnographic interpretation and cognitive explanation are seen as parts of a unified body of anthropological theorizing.

In this paper, I develop a criticism to a method for metaontology, namely, the idea that a discourse’s or theory’s ontological commitments can be read off its sentences’ truth- conditions. Firstly, I will put forward this idea’s basis and, secondly, I will present the way Quine subscribed to it. However, I distinguish between two readings of Quine’s famous ontological criterion, and I center the focus on the one currently dubbed “ontological minimalism”, a kind of modern Ockhamism applied to the mentioned (...) metaontological view. I show that this view has a certain application via Quinean thesis of reference inscrutability but that it is not possible to press that application any further and, in particular, not for the ambitious metaontological task some authors try to employ. The conclusion may sound promising: having shown the impossibility of a semantic ontological criterion, intentionalist or subjectivist ones should be explored. (shrink)

This paper shows how Peirce's semeiotic could be turned into a powerful science. The New Science of Semiotics provides not only a new paradigm and an empirical justification for all these applications, but also a rational and systematic procedure for carrying them out as well. Thus the New Science of Semiotics transforms the philosophy of law into the science of legal scholarship, the discipline that I call jurisology.

Intensional contexts are typically characterised by an apparent failure of either (A) the principle of the inter-substitution of co-referring terms salva veritate, or (B) existential generalisation. The difficulties which are seen to occur do so in contexts involving either modality or the propositional attitudes. In this paper attempts are made to determine whether or not Scheffler’s inscriptional analysis can provide a viable means of accounting for the problems which are thought to occur in intensional contexts. Somewhat unexpectedly, little effort has (...) been made in the past to address this issue. In this paper it is shown that Scheffler’s theory may be employed to account for the difficulties mentioned above, though further work needs to be done to show precisely how his analysis may be adapted so as to handle modal statements. Popular objections to Scheffler’s inscriptionalism are also addressed, particularly in the light of his theory being used to account for the problems of intensionality. It is found that, with certain qualifications, the aforesaid objections do not show Scheffler’s theory to be an unviable means of accounting for the intensionality problems. (shrink)

It is customary in current philosophy of time to distinguish between an A- (or tensed) and a B- (or tenseless) theory of time. It is also customary to distinguish between an old B-theory of time, and a new B-theory of time. We may say that the former holds both semantic atensionalism and ontological atensionalism, whereas the latter gives up semantic atensionalism and retains ontological atensionalism. It is typically assumed that the B-theorists have been induced by advances in the philosophy of (...) language and related A-theorists’ criticisms to acknowledge that semantic atensionalism can hardly stand, but have also maintained that what is essential for the B-theory is ontological atensionalism, which can be independently defended. Here it is argued that the B-theorists have been too quick in abandoning semantic atensionalism: they can still cling to it. (shrink)

A Constructivist Foundation of the Objects of Scientific Empirical Theories. The following considerations are guided by the assumption that the objects of any scientific empirical theory are constructs as well as the theories themselves, the construction of these object-constructs being fundamentally dependent on the theories' functioning in the provision of practically relevant empirical explanations. The relevance of these explanations consists in their contribution to the improvement of at least one practical capacity through enabling the invention of at least one improving (...) kind of practical actions. In an excursus on the origination and the development of the notion of theory within human history the view is held, in contrast to Aristotle, that theorization has always aimed at practical relevance, however in a broader sense of "practical" than that in which Aristotle uses the term "πρακτικός", and that only the practical functions of theory-construction have changed over the times, and their object-constructs correspondingly. The latest form of theory with the above-mentioned function in the development of social practice is the scientific explanatory empirical theory with the descriptive empirical theory now no longer fulfilling a practical function of its own, but only a service-function of data acquisition for the explanatory theory. The object-constructs of strictly scientific empirical theories in the sense of explanatory theories for the improvement of practical capacities are here considered to be empirical quasi-actions, those of the dependent descriptive empirical theories either quasi-instruments or quasi-products or quasi-materials of the respective kind of quasi-actions of the explanatory theory. The empirical quasi-action is here conceived as the latest in a sequence of developing object-constructs that have resulted from different and successively more effective attempts at better survival of human beings and even from prehuman stages of evolution. The author envisages a differentiation of empirical quasi-actions into further sub-categories to provide the conceptual bases for the construction of objects of new kinds of scientific explanatory empirical theories that might become practically relevant for the improvement of new kinds of practical capacities to be preferably improved for the advancement of social practice: Beside the already relevant category of empirical processes are here proposed the further categories of empirical originations of meaning and of empirical originations of practical actions as conceptual bases for object-constructs of future scientific empirical theories.

A radical metaphysical theory typically comes packaged with a semantic theory that reconciles those radical claims with common sense. The metaphysical theory says what things exist and what their natures are, while the semantic theory specifies, in terms of these things, how we are to interpret everyday language. Thus may we “think with the learned, and speak with the vulgar.” This semantic accommodation of common sense, however, can end up undermining the very theory it is designed to protect. This paper (...) is a case study, showing in detail how one popular version of temporal parts theory is self-undermining. This raises the specter that the problem generalizes to other metaphysical theories. (shrink)

Quine’s general approach is to treat ontology as a matter of what a theory says there is. This turns ontology into a question of which existential statements are consequences of that theory. This approach is contrasted favourably with the view that takes ontological commitment as a relation to things. However within the broadly Quinean approach we can distinguish different accounts, differing as to the nature of the consequence relation best suited for determining those consequences. It is suggested that Quine’s own (...) narrowly formal account fails. Then a consideration of the necessitation approach championed by Jackson and Lewis shows that it does not do justice to the role of acknowledging consequences in determining rationality. I suggest that an approach which puts a priori consequence as the key relation does a better job. The task of spelling out the nature of a priori consequence is sketched, along with reasons to doubt the adequacy of the double indexing approach to analysing the a priori. The sorts of relations we can stand in to theories which allow us to inherit ontological commitments are touched on with a number of important philosophical strategies for introducing belief-like attitudes which nevertheless avoid ontological commitment.

That reference is inscrutable is demonstrated, it is argued, not only by W. V. Quine's arguments but by Peter Unger's "Problem of the Many." Applied to our own language, this is a paradoxical result, since nothing could be more obvious to speakers of English than that, when they use the word "rabbit," they are talking about rabbits. The solution to this paradox is to take a disquotational view of reference for one's own language, so that "When I use 'rabbit,' I (...) refer to rabbits" is made true by the meaning of the word "refer." The reference relation is extended to other languages by translation. The explanation for this peculiarly egocentric conception of semantics-questions of others' meanings are settled by asking what I mean by words of my language-is to be found in our practice of predicting and explaining other people's behavior by empathetic identification. I understand other people's behavior by asking what I would do in their place. (shrink)

The Representational Theory of the Mind allows for psychological explanations couched in terms of the contents of propositional attitudes. Propositional attitudes themselves are taken to be relations to mental representations. These representations (partially) determine the contents of the attitudes in which they figure. Thus, Representationalism owes an explanation of the contents of mental representations. This essay constitutes an atomistic theory of the content of formally or syntactically simple mental representation, proposing that the content of such a representation is determined by (...) the intersection of the representation's correlational and control properties. The theory is distinguished from standard information-based accounts of mental content in allowing that the relevant correlations be contingent while insisting on an efferent aspect to mental content. The theory on offer allows for a natural explanation of misrepresentation, finds a niche for the notion of narrow content, welcomes radical first person fallibility with respect to questions of content, admits of mental ambiguity and recognizes that the future of a psychological agent is a factor in determining the content of the agent's present psychological states.

I conceive of inductive logic as a project of explication. The explicandum is one of the meanings of the word `probability' in ordinary language; I call it inductive probability and argue that it is logical, in a certain sense. The explicatum is a conditional probability function that is specified by stipulative definition. This conception of inductive logic is close to Carnap's, but common objections to Carnapian inductive logic (the probabilities don't exist, are arbitrary, etc.) do not apply to this conception.

There is considerable debate in comparative psychology and philosophy over whether nonhuman animals can attribute beliefs. The empirical studies that suggest that they can are shown to be inconclusive, and the main philosophical and empirical arguments that purport to show they cannot are shown to be invalid or weak. What is needed to move the debate and the field forward, it is argued, is a fundamentally new experimental protocol for testing belief attribution in animals, one capable of distinguishing genuine belief-attributing (...) subjects from their perceptual-state attributing and behavior-reading counterparts. Such a protocol is outlined and defended. The rest, it is argued, is in the hands of experimentalists. (shrink)

I outline Brandom’s theory of de re and de dicto belief ascriptions, which plays a central role in Brandom’s overall theory of linguistic communication, and show that this theory offers a surprising, new response to Burge’s (Midwest Stud 6:73–121, 1979) argument for social externalism. However, while this response is in principle available from the perspective of Brandom’s theory of belief ascription in abstraction from his wider theoretical enterprise, it ceases to be available from this perspective in the wider context of (...) his inferential role semantics and his doctrines of scorekeeping and of the expressive role of belief ascriptions in discourse. In this wider context, Brandom’s theory of belief ascriptions implies that Burge’s argument trivially fails to have the disquieting implications for psychological explanations that it is widely taken to have. Yet since this is not trivially so, Brandom’s theory apparently provides a false picture of our practice of interpreting belief ascriptions. I then argue that Brandom might as well accept the alternative picture of interpreting belief ascriptions that Burge’s argument presupposes: even in the context of his overall project, Brandom’s take on our practice of interpreting them does not afford belief ascriptions with the discursive significance Brandom claims they have.

The general question to be considered in this paper points to the nature of the world described by chemistry: what is macro-chemical ontology like? In particular, we want to identify the ontological categories that underlie chemical discourse and chemical practice. This is not an easy task, because modern Western metaphysics was strongly modeled by theoretical physics. For this reason, we attempt to answer our question by contrasting macro-chemical ontology with the mainstream ontology of physics and of traditional metaphysics. In particular, (...) we introduce the distinction between stuff-ontology, proper of chemistry, and individual-ontology, proper of physics. These two ontologies differ from each other in the basic categories of their own structures. On this basis, we characterize individual-ontology in such a way that the features of stuff-ontology will arise by contrast with it. (shrink)

This extract from Lestel's Paroles de singes analyses the methodological debates of the research into the linguistic capabilities of great apes. Lestel uncovers the strategic blindness, methodological fumbling, and other “mirror effects” of these experiments, and reflects on the questions of anthropomorphism and common knowledge. Are the apes simulating language; are the ape-researchers simulating results? Parallels with research into artificial intelligence reveal a preoccupation with questions of cognition.

In this paper, we defend Davidson's program in truth-theoretical semantics against recent criticisms by Scott Soames. We argue that Soames has misunderstood Davidson's project, that in consequence his criticisms miss the mark, that appeal to meanings as entities in the alternative approach that Soames favors does no work, and that the approach is no advance over truth-theoretic semantics.

This essay examines the capacity of language (‘word’) to convey what there is (‘world’). It draws on philosophical thought, which it seeks to apply to law while making specific reference to comparative legal studies, that is, to the investigation of law that is foreign to its interpreter.

If quantum mechanics (QM) is to be taken as an atomistic theory with the elementary particles as atoms (an ATEP), then the elementary particlcs must be individuals. There must then be, for each elementary particle a, a property being identical with a that a alone has. But according to QM, elementary particles of the same kind share all physical properties. Thus, if QM is an ATEP, identity is a metaphysical but not a physical property. That has unpalatable consequences. Dropping the (...) assumption that QM is an ATEP makes it possible to replace the assumption that elementary particles are individuals with the assumption that there are various kinds of elementary stuff that have smallest quantities — the smallest quantity of light, for example, is a photon. The problems about identity disappear, and the explanatory virtues of an ATEP are maintained. (shrink)

The need to distinguish between logical and extra-logical varieties of inference, entailment, validity, and consistency has played a prominent role in meta-ethical debates between expressivists and descriptivists. But, to date, the importance that matters of logical form play in these distinctions has been overlooked. That’s a mistake given the foundational place that logical form plays in our understanding of the difference between the logical and the extra-logical. This essay argues that descriptivists are better positioned than their expressivist rivals to provide (...) the needed account of logical form, and so better able to capture the needed distinctions. This finding is significant for several reasons: First, it provides a new argument against expressivism. Second, it reveals that descriptivists can make use of this new argument only if they are willing to take a controversial—but plausible—stand on claims about the nature and foundations of logic.

Why do people create extra representations to help them make sense of situations, diagrams, illustrations, instructions and problems? The obvious explanation— external representations save internal memory and com- putation—is only part of the story. I discuss seven ways external representations enhance cognitive power: they change the cost structure of the inferential landscape; they provide a structure that can serve as a shareable object of thought; they create persistent referents; they facilitate re- representation; they are often a more natural representation of (...) structure than mental representations; they facilitate the computation of more explicit encoding of information; they enable the construction of arbitrarily complex structure; and they lower the cost of controlling thought—they help coordinate thought. Jointly, these functions allow people to think more powerfully with external representations than without. They allow us to think the previously unthinkable. (shrink)

Central elements of W. V. Quine’s epistemology are widely and deeply misunderstood, including the following. He held from first to last that our evidence consists of the stimulations of our sense organs, and of our observations, and of our sensory experiences; meeting the interpretive challenge this poses is a sine qua non of understanding his epistemology. He counted both “This is blue” and “This looks blue” as observation sentences. He took introspective reports to have a high degree of certainty. He (...) endorsed outright Hume’s “skeptical” argument concerning induction. His naturalized epistemology is simply naturalistic, or scientific, epistemology stripped of the project of rational reconstruction, and is thoroughly normative. Quine was unconditionally a scientific philosopher who took our theories to be answerable ultimately to our perceptual experiences (sensations)—and conditionally an empiricist, empiricism being a scientific theory that has no competitors worthy of the name. I attempt to make all of this clear, and conclude by offering a concise formulation of his epistemology. (shrink)

David Lewis is associated with the controversial thesis that some properties are more eligible than others to be the referents of our predicates solely in virtue of those properties’ being more natural; independently, that is, of anything to do with our patterns of usage of the relevant predicates. On such a view, the natural properties act as ‘reference magnets’. In this paper I explore (though I do not endorse) a related thesis in epistemology: that some propositions are ‘justification magnets’. According (...) to the doctrine of justification magnetism, we have better justification for some propositions than for others solely in virtue of certain features of those propositions; independently, that is, of anything to do with evidential support or cognitive accomplishment. In the course of discussing an objection to justification magnetism I describe (though I do not endorse) a novel approach to epistemology akin to interpretationism in the theory of reference.

Two notable thought experiments are discussed in this article: Reid's thought experiment about whether a being supplied with tactile sensations alone could acquire the conception of extension and Strawson's thought experiment about whether a being supplied with auditory sensations alone could acquire the conception of mind-independent objects. The experiments are considered alongside Campbell's argument that only on the so-called relational view of experience is it possible for experiences to make available to their subjects the concept of mind-independent objects. I consider (...) how the three issues ought to be construed as raising questions about woulds, coulds, or shoulds. (shrink)

The question whether qualities are metaphysically more fundamental than or mere limiting cases of relations can be addressed in an applied symbolic logic. There exists a logical equivalence between qualitative and relational predications, in which qualities are represented as one-argument-place property predicates, and relations as more-than-one-argument-place predicates. An interpretation is first considered, according to which the logical equivalence of qualitative and relational predications logically permits us ontically to eliminate qualities in favor of relations, or relations in favor of qualities. If (...) metaphysics is understood at least in part as an exercise in ontic economy, then we may be encouraged to adopt a property ontology of qualities without quality-irreducible relations, or relations without relation-irreducible qualities. If either strategy is followed, the choice of reducing qualities to relations or relations to qualities will need to be justified on extra-logical grounds. These might include a perceived greater intuitiveness, explanatory fecundity, compatibility with cognitive ontogeny or developmental psychology, expressive or explanatory elegance or cumbersomeness, and an open-ended list of philosophical motivations that could reasonably favor the ontic prioritization of qualities over relations or relations over qualities. Despite its intuitive appeal, the thesis that logical equivalence together with extra-logical preferences justifies unidirectional ontic reduction of relations to qualities or qualities to relations is rejected in light of the more defensible proposition that the logical equivalence of qualitative and relational predications actually supports the opposite conclusion, that both qualities and relations are logically indispensable to a complete ontology of properties. The logical equivalence of qualitative and relational predications, insofar as we continue to observe the distinction, makes it logically necessary ontically for both qualities and relations to exist whenever either one exists. That logically equivalent qualitative and relational predications have as their truth-makers the exemplification by objects of both qualities and relations as equi-foundational properties further suggests that there is no deeper logical distinction between qualities and relations, but only two convenient lexical-grammatical designations for property predications involving one- versus more-than-one-argument-place.

This paper will discuss the origin of the human mind, and the qualitative discontinuity between human and animal cognition. We locate the source of this discontinuity within the language faculty, and thus take the origin of the mind to depend on the origin of the language faculty. We will look at one such proposal put forward by Hauser et al. (Science 298:1569-1579, 2002), which takes the evolution of a Merge trait (recursion) to solely explain the differences between human and animal (...) cognition. We argue that the Merge-only hypothesis fails to account for various aspects of the human mind. Instead we propose that the process of lexicalisation is also unique to humans, and that this process is key to explaining the vast qualitative differences. We will argue that lexicalisation is a process through which concepts are reformatted to be able to take on semantic features and to take part in grammatical relations. These are both necessary conditions for a grammatical mind and the increased ability to express conceptual content. We therefore propose a possible explanans for the discontinuity between humans and animals, namely that merge with lexicalisation (and consequently semantic features and grammatical relations) is a minimal requirement for the human mind.
