Extensional scientific realism is the view that each believable scientific theory is supported by the unique first-order evidence for it and that if we want to believe that it is true, we should rely on its unique first-order evidence. In contrast, intensional scientific realism is the view that all believable scientific theories have a common feature and that we should rely on it to determine whether a theory is believable or not. Fitzpatrick argues that extensional realism is (...) immune, while intensional realism is not, to the pessimistic induction. I reply that if extensional realism overcomes the pessimistic induction at all, that is because it implicitly relies on the theoretical resource of intensional realism. I also argue that extensional realism, by nature, cannot embed a criterion for distinguishing between believable and unbelievable theories. (shrink)

I discuss two competing theories of the progressive: the theory proposed in Parsons (1980, 1985, 1989, 1990) and the theory proposed in Landman (1992). These theories differ in more than one way. Landman regards the progressive as an intentional operator, while Parsons doesn't. Moreover, Landman and Parsons disagree on what uninflected predicates denote. For Landman, cross the street has in its denotation complete events of crossing the street; the aspectual contribution of English simple past (perfective aspect) is the identity function. (...) For Parsons, both complete and incomplete events of crossing the street can be in the denotation of the base VP; perfective aspect restricts its denotation to the events that culminate. I present a version of ParsonÕs theory that avoids the problems raised by Landman, in particular the problem posed for Parsons by creation verbs. The repaired version and Landman's theory still differ in the way they analyze uninflected verbs. The repaired version and Landman's theory still differ in the way they analyze uninflected predicates. I present evidence from Slavic languages that both theories are needed. Finally, I discuss some evidence that may favor one or the other approach to the semantics of the English progressive. (shrink)

The Mohist School's logical study focuses mainly on the following inference rule: suppose that N and M are coextensive terms, or N a subset of M; it follows that if a verb can appear in front of N, it can also appear in front of M. That is, if 'VM' then 'VN', where V is some extensional verb. Such an approach to logical inference necessitates the study of logical relations among nouns, verbs, and the relations between these two types of (...) words. Evidence is offered here that the Mohists clearly distinguished extensional verbs from intensional verbs, and that this insight enabled them to say, among other things, that VN does not follow from VM, even in cases where N is M or contained in M, as long as the V in question is an intensional verb.

Nurses in Ghana believe that training, practise, practitioner and policy reforms are required for total nursing profession reform to be effective. Their views for role reformation in the nursing profession, which is currently needed, are not only academic but also clinically relevant in the pursuit of health equity and quality nursing care. We explored and described nurses’ views on their roles in the profession using data collected from 24 professional nurses in three regional hospitals in Ghana. Using an inductive descriptive (...) qualitative design, data were gathered and analysed using a qualitative content analysis to describe the views of the nurses. Four major themes, namely practise reforms, practitioner reforms, training reforms and policy reforms have emerged in relation to role reformation in the nursing profession. Three strategic areas, practitioner attitudes, new training modalities and policy realignment, must be reviewed and remodelled for better positioning of the nursing profession before its entire role reformation.

Alonzo Church famously provided three principal competing criteria for “strict synonymy,” i.e., sameness of semantic content. These are his Alternatives (0), (1), and (2)—numbered in order of increasing course-grainedness of content. On Alternative (2), expressions are deemed strictly synonymous iff they are logically equivalent. This criterion seems hopeless as an account of the objects of propositional attitude. On Alternative (1), expressions are deemed synonymous iff they are λ-convertible. Alternative (1) also evidently conflicts with discourse about the attitudes. On Alternative (0), (...) expressions are deemed strictly synonymous iff they are “synonymously isomorphic” in Church’s sense. On Alternative (0), semantic content is so fine-grained that not even “Romeo loves Juliet” and “Juliet is loved by Romeo” qualify as strictly synonymous. A fourth alternative, here called “Alternative (3),” deems expressions strictly synonymous iff they are co-intensional, i.e., they have the same semantic extension with respect to the same possible worlds. This criterion’s notion of content is even more course grained than that of Alternative (2). Several objections to Alternative (3) are considered. (shrink)

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.

Evidence is drawn together to connect sources of inconsistency that Frege discerned in his foundations for arithmetic with the origins of the paradox derived by Russell in "Basic Laws" I and then with antinomies, paradoxes, contradictions, riddles associated with modal and intensional logics. Examined are: Frege's efforts to grasp logical objects; the philosophical arguments that compelled Russell to adopt a description theory of names and a eliminative theory of descriptions; the resurfacing of issues surrounding reference, descriptions, identity, substitutivity, (...) paradox in the debates concerning modal and intensional logics; the development of the New Theory of Reference. I consider this to be the philosophical ground upon which the debates regarding that theory should take place. (shrink)

According to the so-called Classical Theory, concepts are mentally represented by individually necessary and jointly sufficient application conditions. One of the principal empirical objections against this view stems from evidence that people judge some instances of a concept to be more typical than others. In this paper we present and discuss four empirical studies that investigate the extent to which this ‘typicality effect’ holds for the concept of basic needs. Through multiple operationalizations of typicality, our studies yielded evidence (...) for a strong effect of this kind: Participants tended to recall the same core examples of the concept in a free-listing task. They judged some basic needs to be more typical than others. The items that were judged to be more typical were listed more frequently in the free-listing task. These items were listed earlier on in the free-listing task. Typical basic needs, as well as non needs, were classified faster than atypical basic needs in a reaction time study. These findings suggest that the concept of basic needs may have a non-classical structure. If so, the quest for a simple and robust intensional analysis of the concept may be futile. (shrink)

In a series of articles in this journal, Michael Tye (2002) and Paul Noordhof (2001, 2002) have sparred over the correct explanation of the putative invalidity of the following argument: the pain is in my fingertip; the fingertip is in my mouth; therefore, the pain is in my mouth. Whereas Tye explains the failure of the argument by stating that “pain “creates an intensional context, Noordhof maintains that the “in” in ‘the pain is in my fingertip’ is not spatial, (...) but has state-attributing character. In this paper, we offer a third account, explaining the failure of the argument through state-attributing pragmatic implicatures. Empirical evidence is provided in support of this account. (shrink)

It is generally assumed that humans are the only animals who can possess a concept of death. However, the ubiquity of death in nature and the evolutionary advantages that would come with an understanding of death provide two prima facie reasons for doubting this assumption. In this paper, my intention is not to defend that animals of this or that nonhuman species possess a concept of death, but rather to examine how we could go about empirically determining whether animals can (...) have a concept of death. In order to answer this question, I begin by sketching an account of concept possession that favours intensional classification rather than mere extensional discrimination. Further, I argue that the concept of death should be construed as neither binary nor universal. I then present a proposal for a set of minimal conditions that must be met to have a concept of death. I argue that having a minimal understanding of death entails first expecting a dead individual to be alive, and then grasping its non-functionality and irreversibility. Lastly, I lay out the sort of observational and experimental evidence that we should look for to determine whether animals have the capacity for a minimal comprehension of death. (shrink)

In this paper, I discuss the distribution and interpretation of free choice items (FCIs) in Greek, a language exhibiting a lexical paradigm of such items distinct from that of negative polarity items. Greek differs in this respect from English, which uniformly employs any. FCIs are grammatical only in certain contexts that can be characterized as nonveridical (Giannakidou 1998, 1999), and although they yield universal-like interpretations in certain structures, they are not, I argue, universal quantifiers. Evidence will be provided that (...) FCIsare indefinites; the quasi-universal effect is shown to be the result of binding by an operator with universal force. Additionally, the limited distribution of FCIs in non veridical contexts can be accounted for by analyzing them as indefinites which must always be interpreted in an intensional type. The difference between ``regular'' indefinites and FCIs, therefore, is reduced to a type difference which captures the fact that only the latter exhibit limited distribution: because of their intensional type, FCIs will be grammatical only in contexts providing alternatives (worlds or situations), and nonveridical contexts do exactly this. By contrast, FCIs are excluded from veridical and episodic contexts because these provide no alternatives and hence do not satisfy the lexical semantic requirement ofFCIs. The proposed analysis is supported by data from other languages as well (Spanish, Catalan,French) and has important consequences regarding the analysis of English any. If FCIs are not universal quantifiers but indefinites, then the usual ambiguity thesis (free choice any being universal, negative polarity any an existential) can no longer be maintained, at least not as one in terms of quantificational force.

This article presents arguments and evidence that run counter to the widespread assumption among scholars that humans are intuitive Cartesian substance dualists. With regard to afterlife beliefs, the hypothesis of Cartesian substance dualism as the intuitive folk position fails to have the explanatory power with which its proponents endow it. It is argued that the embedded corollary assumptions of the intuitive Cartesian substance dualist position (that the mind and body are diff erent substances, that the mind and soul are (...) intensionally identical, and that the mind is the sole source of identity) are not compatible with cultural representations such as mythologies, funerary rites, iconography and doctrine as well as empirical evidence concerning intuitive folk reasoning about the mind and body concerning the afterlife. Finally, the article suggests an alternative and more parsimonious explanation for understanding intuitive folk representations of the afterlife. (shrink)

summaryMartin and Pfeifer have claimed“that the most typical characterizations of intentionality… all fail to distinguish … mental states from …dispositional physical states.”The evidence they present in support of this thesis is examined in the light of the possibility that what it shows is that intentionality is the mark, not of the mental, but of the dispositional. Of the five marks of intentionality they discuss a critical examination shows that three of them, Brentano's inexistence of the intentional object, Searle's directedness (...) and Anscombe's indeterminacy, are features which distinguish T‐inten Tional/dispositional The other two are either, as in the case of Chisholm's permissible falsity of a propositional attitude ascription, a feature of linguistic utterances too restricted in its scope to be of interest, or, as in the case of Frege's indirect reference/Quine's referential opacity, evidence that the S‐intenSional locution is a quotation either of what someone has said in the past or might be expected to say, if the question were to arise at some time in the future.

When do children acquire a propositional attitude folk psychology or theory of mind? The orthodox answer to this central question of developmental ToM research had long been that around age 4 children begin to apply “belief” and other propositional attitude concepts. This orthodoxy has recently come under serious attack, though, from two sides: Scoffers complain that it over-estimates children’s early competence and claim that a proper understanding of propositional attitudes emerges only much later. Boosters criticize the orthodoxy for underestimating early (...) competence and claim that even infants ascribe beliefs. In this paper, the orthodoxy is defended on empirical grounds against these two kinds of attacks. On the basis of new evidence, not only can the two attacks safely be countered, but the orthodox claim can actually be strengthened, corroborated and refined: what emerges around age 4 is an explicit, unified, flexibly conceptual capacity to ascribe propositional attitudes. This unified conceptual capacity contrasts with the less sophisticated, less unified implicit forms of tracking simpler mental states present in ontogeny long before. This refined version of the orthodoxy can thus most plausibly be spelled out in some form of 2-systems-account of theory of mind. (shrink)

David Lewis's modal realism claims that nothing can exist in more than one world or time, and that statements about how something would have been are to be analysed in terms of its counterpart. I first explain why the counterpart relation depends on de re modal statements in an intensional language, so that intuitive properties of similarity relations cannot be used to show that the counterpart relation is not an equivalence relation. I then look at test sentences in (the (...) intensional) natural language, and show that none of them provide compelling evidence that a counterpart semantics is needed. (shrink)

In evolutionary cognitive archaeology, the school of thought associated with the traditional framework has been deeply influenced by cognitivist intuitions, which have led to the formulation of mentalistic and disembodied cognitive explanations to address the emergence of artifacts within the archaeological record of ancient hominins. Recently, some approaches in this domain have further enforced this view, by arguing that artifacts are passive means to broadcast/perpetuate meanings that are thoroughly internal to the mind. These meanings are conveyed either in the form (...) of a Language of Thought, constituted by sub-personal, content-bearing mental representations, or in that of a natural language. In both cases, however, material culture stands as the physical derivative of computations run over representations, which include abstract concepts, semantic relationships, and meta-representations about intensional states, a conception hereby indicated as “representational apriorism”. In this paper, I will argue that such mentalistic models are plagued by the fundamental problems of content, substance, and origin, which affect the representational substrates required for the production of artifacts. At the same time, these models fail the criterion of minimalism at the crux of conditional cognitive archaeology, because they propose overly costly explanations which are insufficiently constrained by material evidence. An alternative proposal, based on the principles of radical enactive cognitive science, is hereby introduced in order to counter this mentalistic drift. It is concluded that a radical enactive cognitive archaeology is able to dissolve the deep problems confronting the mentalistic paradigm, while providing minimalistic cognitive explanations about the emergence of Paleolithic artifacts.

We no longer have any texts, any past, but just interpretations of them. The evident multi -interpretability of a text causes it gradually to lose its capacity to function as arbiter in the historical debate. It is necessary to define a new link with the past based on a complete and honest recognition of the position in which we now see ourselves placed as historians. In recent years, many people have observed our changed attitude towards the phenomenon of information. For (...) postmodernism, science and information are independent objects of study which obey their own laws. Language and art are not situated opposite reality but are themselves a pseudo-reality and are therefore situated within reality. Because of the relation between the historiographical view and the language used by the historian to express his view - a relation which nowhere intersects the domain of the past -historiography possesses the same opacity and intensional dimension as art. The essence of postmodernism is precisely that we should avoid pointing out essentialist patterns in the past. There is reason to assume that our relation to the past and our insight into it will in future be of a metaphorical nature rather than a literal one. (shrink)

Aristotle's philosophically most explicit and sophisticated account of the concept of a (primary-)universal proof is found, not in "Analytica Posteriora" 1.4, where he introduces the notion, but in 1.5. In 1.4 Aristotle merely says that a universal proof must be of something arbitrary as well as of something primary and seems to explain primacy in extensional terms, as concerning the largest possible domain. In 1.5 Aristotle improves upon this account after considering three ways in which we may delude ourselves into (...) thinking we have a primary-universal proof. These three sources of delusion are shown to concern situations in which our arguments do establish the desired conclusion for the largest possible domain, but still fail to be real primary-universal proofs. Presupposing the concept of what may be called an immediate proof, in which something is proved of an arbitrary individual, Aristotle in response now demands that a proof be immediate of the primary thing itself and goes on to sketch a framework in which an intensional criterion for primacy can be formulated. For the most part this article is a comprehensive and detailed commentary on Aristotle's very concise exposition in 1.5. One important result is that the famous passage 74a17-25 referring to two ways of proving the alternation of proportions cannot be used as evidence for the development of pre-Euclidean mathematics.

Frege puzzles exploit cognitive differences between co-referential terms. Traditionally, they were handled by some version of Frege’s distinction between sense and reference, which avoided disruptive consequences for epistemology. However, the Fregean programme did not live up to its original promise, and was undermined by the development of theories of direct reference; for semantic purposes, its prospects now look dim. In particular, well-known analogues of Frege puzzles concern pairs of uncontentious synonyms; attempts to deal with them by distinguishing idiolects or postulating (...) ‘narrow contents’ or elaborate forms of context-sensitivity are inadequate or semantically implausible. Although ascriptions of knowledge, belief, and other attitudes are ubiquitous in epistemology, epistemologists have not properly come to terms with the surprising consequences of anti-Fregean semantic accounts of attitude ascriptions. In ‘A Puzzle about Belief ’, Saul Kripke shows that natural-seeming disquotational principles for ascribing belief lead to apparently unacceptable consequences, including outright contradictions, in problem cases. Such disquotation principles, I argue, are best regarded not as conceptual connections but just as heuristics in the psychological sense, quick and easy ways of assessing belief ascriptions, usually accurate under normal conditions but far from 100% reliable. I discuss similar heuristics for ascribing knowledge and other attitudes. That the principles have a merely heuristic status need not be pre-theoretically manifest to their users. This view vindicates Kripke’s conclusion that it would be wrong-headed to draw semantic conclusions from Frege puzzles. I discuss the epistemological consequences of an anti-Fregean approach to Frege puzzles, including for Kripke’s cases of the contingent a priori and the necessary a posteriori, but also for evidence, for epistemic modalities, and for epistemic and subjective conceptions of probability. Anna Mahtani’s recent identification of Frege puzzles for the ex ante Pareto Principle as used in welfare economics provides an interesting example. I suggest a model-building methodology as the most promising way of handling at least some of the difficulties. A final issue is the choice between different anti-Fregean approaches to semantics, from very coarse-grained intensional approaches on which sentences express functions from possible worlds to truth-values to more fine-grained hyperintensional approaches on which sentences express functions from possible or impossible worlds to truth-values or else Russellian structured propositions. Some of the hyperintensional theories violate semantic compositionality. More generally, since our attitude ascriptions rely on heuristics, they should be expected to exhibit some level of error; although hyperintensional approaches may be able slightly to reduce the level of postulated error, they do so at the cost of vastly increased theoretical complexity, and so have weak explanatory power. Methodologically, a simple intensional approach does better. (shrink)

Scott Soames has recently argued that traditional accounts of propositions as n-tuples or sets of objects and properties or functions from worlds to extensions cannot adequately explain how these abstract entities come to represent the world. Soames’ new cognitive theory solves this problem by taking propositions to be derived from agents representing the world to be a certain way. Agents represent the world to be a certain way, for example, when they engage in the cognitive act of predicating, or cognizing, (...) an act that takes place during cognitive events, such as perceiving, believing, judging and asserting. On the cognitive theory, propositions just are act types involving the act of predicating and certain other mental operations. This theory, Soames argues, solves not only the problem of how propositions come to represent but also a number of other difficulties for traditional theories, including the problem of de se propositions and the problems of accounting for how agents are capable of grasping propositions and how they come to stand in the relation of expression to sentences. I argue here that Soames’ particular version of the cognitive theory makes two problematic assumptions about cognitive operations and the contents of proper names. I then briefly examine what can count as evidence for the nature of the constituents of the cognitive operation types that produce propositions and argue that the common nature of cognitive operations and what they operate on ought to be determined empirically in cross-disciplinary work. I conclude by offering a semantics for cognitive act types that accommodates one type of empirical evidence. (shrink)

Donald Davidson suggested that, in attempting to give meaning theories, we should proceed via giving truth theories. For the programme of truth-theoretic semantics to be successful, two tasks need to be accomplished. First, it has to be shown that natural languages are actually amendable to truth theoretic treatment. The second task is to show how we can bridge the gap between a truth theory and a genuine meaning theory. This second task is necessitated by the simple fact that truth theories (...) by themselves are too weak to satisfy the central desideratum for a meaning theory. In a recent paper, Greg Ray suggests that the goal of giving meaning theories can easily be achieved, not by supplementing the truth-theoretic apparatus, but by doing away with it altogether. In particular, he proposes that what he calls means-that theories meet all the desiderata on meaning theories, and that ‘anyone with basically Davidsonian commitments must accept the means-that approach as viable and that it has certain evident virtues’. This paper argues that theories along Ray's lines do not satisfy the central desideratum for meaning theories. Ray's belief to the contrary rests on a common misunderstanding of what this desideratum amounts to. As I indicate in the final section of the paper, there perhaps is a way of substantially amending Ray's approach in order to meet the central desideratum. However, in an ironic twist, this will require giving a full-fledged truth theory for the metalanguage, including its intensional constructions like ‘means that’ – precisely the project Ray attempted to avoid.

In this chapter, I am going to discuss a very interesting case brought to our attention by Saul and references therein: NP-related substitution failure in simple sentences. Whereas it is well known that opacity occurs in intensional contexts and that in such contexts it is not licit to replace an NP with a co-referential one, one would not expect that substitution failure should also be exhibited by simple sentences in the context of stories about Superman. The suggested explanation of (...) these cases is to posit an embedding explicature, that is to say the insertion of structure that ipso facto creates an intensional context capable of blocking substitution. I consider various complications to this story in the light of important objections by García-Carpintero and, finally, I consider how this story fares when one applies constraints on explicatures along the lines of those proposed by Hall in an interesting paper.In general, this chapter exploits interesting considerations by Norrick on the structural similarities between stories and indirect reports. Norrick believes there are important differences, but he is inclined to concede that we could study structural similarities. An important similarity, brought out by the examples discussed by Saul, is that the narrative frame, once it is inserted into the interaction, can be left implicit and, during the act of narrating or referring to the story, one need not repeat the words ‘the story says’ or ‘we are told that…’ every time. Although implicit, these words are heard because they do some work at the structural level, as is shown by this attempt to resolve an otherwise intractable philosophical problem. The explicatures of simple sentences are perceived because they are integrated into the speakers’/hearers’ perception of the overall plan of discourse, as Haugh most interestingly notes:As Haugh and Jaszczolt note, this means that any putative “communicative intention of A is embedded within his higher-order intention”. In other words, to figure out the implicature that evidently arises here, the participants are necessarily making inferences about some kind of overall aim. According to this view, then, inferences about the intended implicature arise concomitant with inferences about the overall aim of the speaker.It follows from the considerations by Haugh that, since the explicature connected with simple sentences depends on the perception of the overall aim or plan of the conversation, it is not easily cancelled. Readers can check by themselves that the explicatures due to simple sentences cannot be cancelled, as cancelling them would involve returning to illogical discourses.. Haugh’s considerations about the overall aim of the discourse are precious in explaining how the embedding explicatures I posit are calculated once and for all for the whole stretch of the discourse framed by the narrative act.

At Prior Analytics II 22.68a16–21, Aristotle argues that if A is predicated of all B and C and nothing else, and B is predicated of all C, then A and B convert. In justifying his argument, however, he appears to claim that B is not predicated of all A. This claim has long been a cause of puzzlement to commentators. A widespread view is that the kind of conversion discussed in the passage at issue should be explained in both extensional (...) and intensional terms. After providing some textual evidence that Aristotle only apparently claims that B is not predicated of all A, I give a purely extensional account of Aristotle’s argument. This account is plausible, conservative and simpler than any of the intensional accounts that have been proposed so far. (shrink)

This article discusses the nature of numerals and the plausibility of their special semantic and epistemological status as proper names of numbers. Evidence is presented that minimizes the difference between numerals and other devices of direct reference. The availability of intensional contexts within formalised metamathematics is exploited to shed light on the relation between formal numerals and numerals.

In this paper, I evaluate the claim that the equivalence of multiple intensionally distinct definitions of random sequence provides evidence for the claim that these definitions capture the intuitive conception of randomness, concluding that the former claim is false. I then develop an alternative account of the significance of randomness-theoretic equivalence results, arguing that they are instances of a phenomenon I refer to as schematic equivalence. On my account, this alternative approach has the virtue of providing the plurality of (...) definitions of randomness with conceptual unity and a rationale for certain investigations that are carried out in the field.

Deduction leads to causal explanation in phylogenetic inference when the evidence, the systematic character, is conceptualized as a transformation series. Also, the deductive entailment of modus tollens is satisfied when those kinds of events are operationalized as patristic difference. Arguments to the contrary are based largely on the premise that character-states are defined intensionally as objects, in terms of similarity relations. However, such relations leave biologists without epistemological access to the causal explanation and explanatory power of historical statements. Moreover, (...) the prediction-making to which those kinds of relations are limited in practice can lead to a category error—the mental conversion of an abstraction into a thing . The latter practices and problems characterize pattern cladistics, taxa being interpreted as homeostatic property cluster natural kinds, and other instrumentalist research programs. (shrink)

Davidson holds that thinkers cannot employ radically different conceptual schemes, but he does not deny the fact that small-scale conceptual divergences are possible. He defends the former claim against Quine by appealing to interpretivism, the idea that ascriptions of intensional states to a speaker do no more than systematically record facts about the speaker’s behavior. From interpretivism it follows that it is theoretically irrelevant which set of concepts an interpreter uses to state her theory of meaning. This is what (...) allows Davidson to avoid conceptual relativism while accepting Quine’s thesis that behavioral evidence necessarily underdetermines assignments of meaning to speakers. However, as Davidson seems not to have realized, interpretivism also rules out the possibility of uncontroversial, small-scale conceptual differences. This fact, I argue, should lead us to reject interpretivism. (shrink)

Werkmeister's new book, The Basis and Structure of Knowledge is the second major attempt in recent years to defend the idealistic theory of knowledge. The first was Blanshard's Nature of Thought; and it is worth noticing that both authors, in undertaking the defense of a position long in the shadows, are well aware of contemporary developments in logic and technical philosophy. Werkmeister freely acknowledges his debt to Blanshard; yet his work differs in scope from the latter's in at least two (...) ways. Firstly, the more recent book is concerned largely with the epistemological analysis of meaning and truth and hardly at all with what an older generation called "philosophical psychology," while philosophical psychology fills all of the first and part of the second volume of Blanshard's work. In my opinion, this is all to the good. (That our generation inverts the error and too often indulges in psychological philosophy is another story!) Secondly, Werkmeister presents us with detailed analyses of scientific method, of the structure of scientific theories, and of mathematics, all three areas to which Blanshard pays virtually no attention. The First Part of Werkmeister's book treats of Language and Meaning; the Second of Truth and the World About Us, the Third of Formal Knowledge, and the Fourth Part deals with Empirical Knowledge. But there is a fundamental thesis that runs through all of this. The analysis of each of these four domains reveals, according to Werkmeister, that only a coherence theory of meaning and truth can adequately reflect the criteria actually used by science and commonsense. It is not my intention to rehearse here the familiar dialectic of the arguments for and against this doctrine; the less so, since Werkmeister himself gives a useful review of both sides of the controversy. Rather, I want to try to fix as precisely as possible, within the context of Werkmeister's discussion, the nature of the difference between coherence theories on the one hand and correspondence theories on the other. This difference has not always been too clearly stated; it even seems that recent developments in linguistic analysis have been the occasion for some new confusions on this very point. For coherence theorists who have recognized that philosophical semantics is a "formal" discipline now insist that "to say what a symbol means is not to relate it to an object, but to give it an interpretation in terms of other symbols," as Ayer2 has recently put it. This seems to contradict the "comparison with fact" feature of the traditional realistic formulations of the correspondence view. A superficial bystander could even believe that the correspondence theorists have given up their original position, since both sides now agree that truth is a matter of a relation between symbols. Such agreement, as I hope to show, is more apparent than real, for what is now at stake is the nature of that "intrasymbolic relation." And on this nature the two parties disagree. There is little doubt that Werkmeister's book appears at a moment more propitious for the advocacy of the coherence theory of truth than did Blanshard's. In the near decade that separates the two works the intellectual climate has become, for better or for worse, considerably more favorable to a reconsideration of, and possibly even a reconciliation with, some of the major tenets of rationalism. This is reflected in the current discussion regarding the contrary-to-fact conditional, the dissatisfaction with material implication, and the correlative concern for a more adequate analysis of the concept of a natural law. It is evident too in the revived enthusiasm for intensional logic and in the related interest in the modalities. As uncompromising an empiricist as C. L. Lewis, with whom, by the way, Werkmeister shares a common Kantian background, has introduced into his latest work a "congruence" theory of truth which, despite the substitution of a so-called "probability" inference for necessary inference, looks very much like the coherance criterion all over again. So Werkmeister's book should be welcome for its clear presentation of the relevant issues; and even those who disagree with him can admire the candor and forthrightness with which he champions what remains, despite vacillations, an essentially unpopular position.

The transition in Kant's writings form a pre-critical to a critical standpoint has been thoroughly documented with regard to Kant's changing conception of metaphysics, theory of knowledge, and philosophy of mathematics. But a similar alteration in standpoint in Kant's philosophy of logic has received little or no attention. This paper documents the existence of this shift in Kant's philosophy of logic and examines its nature. The resulting analysis provides evidence for the thesis that Kant began with a strictly (...) class='Hi'>intensional term logic and with a theory of inference based on the analytic composition of concepts, and ended with a view of logic which, while remaining fundamentally intensional and term-based, shows movement towards a logic of propositions and propositional connectives.

There is a certain argument against the principle of the indiscernibility of identicals, or the thesis that whatever is true of a thing is true of anything identical with that thing. In this argument, PInI is used together with the self-evident principle of the necessity of self-identity to reach the conclusion, which is held to be paradoxical and, thus, fatal to PInI. My purpose is to show that the argument in question does not have this consequence. Further, I argue that (...) PInI is a universally valid principle which can be used to prove the necessity of identity. (shrink)

Any neurobiological model claiming explanation of a complex human phenomenon should start with an explicit definition of the explanandum. If a classical intensional definition is impossible, we can use a descriptive definition by listing necessary criteria. This commentary suggests four meta-criteria that different proposed criteria of consciousness should fulfill: phenomenological consensus, empirical evidence, domain specificity, and non-circularity.

This paper is about - cognitive science's claim to obtain an empirically theory of human intelligence by experiments with intelligent machines; - the question, whether simulation yields/is explanation , i.e. whether the theory explaining the behaviour of a thing A, appropriately abstracted, as well explains the behaviour of a thing B, different in type from A, when A's and B's behaviours are indistinguishable; - the question, whether the Aristotelian ontic distinction between the natural and the artificial was in fact extinguished (...) by Descartes' materialistic intensional ontology; this question is denied by evidence of the existence of different theories of artificial and natural magnetism in current physics; - and about the comparison of the current theories of magnetism, of artificial or electromagnetism and of natural or ferromagnetism with the result that there is no uniform theory explaining all kinds of magnetism to be gained out of Maxwell's theory. Thus by counterexample is demonstrated that cognitive science's claim to obtain a theory of natural intelligence by the S:E-strategy is to be refused. Descartes' premise of the ontic indifference of the size of physical magnitudes is introduced as basis of the S:E-claim and its refutation as cause of the partial continuation of the ontic distinction between natural and artificial things in physics.

How do modal expressions determine which possibilities they range over? According to the Modal Anchor Hypothesis (Kratzer in _The language-cognition interface: Actes du 19_ _e_ _congrès international des linguistes_, Libraire Droz, Genève, 179–199, 2013 ), modal expressions determine their domain of quantification from particulars (events, situations, or individuals). This paper presents novel evidence for this hypothesis, focusing on a class of Spanish relative clauses that host verbs inflected in the subjunctive. Subjunctive in Romance is standardly taken to be licensed (...) only in a subset of intensional contexts. However, in our relative clauses, subjunctive is exceptionally licensed in extensional contexts. At the same time, the interpretation of these relative clauses still involves modality, a type of modality that targets the goals of the agent of the main event. We argue that the pattern displayed by these relative clauses follows straightforwardly if subjunctive is associated with a modal operator that, like modal indefinites (Alonso-Ovalle and Menéndez-Benito in _Journal of Semantics_ 35(1):1–41, 2017 ), can project its domain from a volitional event. Overall, our proposal supports the event-based analysis of mood (Kratzer in Evidential mood in attitude and speech reports. Talk delivered at the 1st Syncart Workshop, Siena, July 13, 2016 ; Portner and Rubinstein in _Natural Language Semantics_ 28:343–393, 2020 ) and extends its application beyond attitudinal and modal complements.

Hyperintensionality – the failure of substitutivity salva veritate of intensionally equivalent expressions – is one of the most debated topics in recent philosophy of language. Being a phenomenon that affects a wide variety of different sentential contexts, a question concerning its source arises: is hyperintensionality something that can originate from actual features of the world, or it is simply some kind of representational phenomenon, which entirely depends on our conceptual faculties and preferred semantics? After a brief general introduction to the (...) topic from the semantic standpoint, in the present work I defend a view developed by Daniel Nolan, according to which hyperintensionality can be a worldly, non-representational phenomenon. I first reconstruct Nolan’s view and argument for worldly hyperintensionality, understood through the comparison with de re intensional modality. Then, I address the main criticism that has been raised against it, developing three objections. Evidence for worldly hyperintensionality is thereby presented, by focusing on a paradigmatic trigger: counterpossible conditionals. I provide two jointly sufficient criteria for a counterpossible to be a genuine instance of worldly hyperintensionality, then illustrate three case studies from scientific practices that all rely on counterpossible reasoning: reducibility in relative computability theory; scientific explanation of certain substances’ essential properties; and emergent molecular structure in chemistry. Each of them is evaluated by checking if it satisfies the criteria for worldly hyperintensionality, leading to the detection of patterns of counterpossible dependence occurring in at least some specific instances of the case studies discussed. Finally, I suggest a possible realist reading of such dependence relation, locating its relata in the world, independently from our representations. (shrink)

This note argues that, insofar as contemporary mathematics is concerned, there is overwhelming evidence that if mathematical objects are structures, then isomorphism should not be taken as their identity condition. This goes against a common version of structuralism in the philosophical literature. Four areas are presented in which identifying isomorphic structures or objects leads to contradiction or inadequacy. This is followed by a philosophical discussion on possible ways to approach the distinction, and a section on the possibility of proceeding (...) intensionally, as is done in e.g.\ the Univalent Foundations program.

In two separate studies, published some four years apart, Robert McRae has argued the provocative thesis that the idea of extension is not to be numbered among the ideas accounted innate by Descartes, but among the adventitious. He has defended this view despite explicit statements to the contrary by Descartes both in the Correspondence and in the second part of the Principles of Philosophy. Against such evidence McRae has urged the overriding importance of the sixth Meditation, where, he alleges, (...) Descartes asserts “unequivocally… that the idea of extension is produced in us by bodies and is therefore not innate”. It is only in the later of the two studies that McRae's reasons for regarding the testimony of the sixth Meditation as authoritative are fully spelt out. Express statements to the contrary “must give away”, he writes, “for the proof of the existence of body by the adventitious idea of it is absolutely crucial to the Meditations”. In this paper I propose to challenge McRae's interpretation of the extension of the concept “innate idea”, while acknowledging his signal contribution to the clearing up of the intensional meaning, or rather meanings, of the concept of innateness. My thesis is that “extension” is an innate idea, though constraints of time will allow me to do little more than try to show that McRae's stated reasons for rejecting this view are not compelling.

Semantic framework of the discussion about the equivalence and interchangeability of the original drugs and generics is considered in the article. Generics are identical to the original drugs in terms of chemical structure, nevertheless some patients and doctors consider that generics are less effective and have more severe side effects than original drugs. These discussions are considered as an example of a public deliberation concerning the achievements of technoscience. The conflicting parties determined the identity either from the chemical structure of (...) the drug (according to D. Chalmers – secondary intensional) or from the phenomenal characteristics of the situation of its application (primary intensional). In this regard, the method of resolving the conflict is the alignment of the hierarchy of methods for determining equivalence in biomedicine. The methodology of evidence-based medicine already has such a hierarchy, which makes it possible to determine the validity of outcomes of clinical trial. According to this hierarchy, the phenomenal characteristics of the outcome of treatment (quality and life expectancy of patients) are more important than instrumentally established indicators. Thus, new clinical data on the efficacy and safety of a generic should give the opportunity to cancel the recognition of drug equivalence. More generally, this means that technoscience achievement which directly affects a person can only be assessed by him/her. The recognition of such priority is the basis of the ‘division of linguistic labor’ during public deliberation concerning the achievements of technoscience. (shrink)

Chapter VI discusses a few assumptions which underlie the proposed reconstruction of Hegel's procedures. It is shown that certain equivalents of such assumptions are either explicitly accepted by Hegel, or they are consequences of theses he subscribed to. Finally, it is suggested that some of these assumptions envisage a conception of language and philosophy which has an interesting parallel in Wittgenstein's later work. Such a conception sets philosophy sharply apart from the sciences, and deemphasizes the formation of contradictions. The general (...) relationship between vagueness and contradiction is briefly explored to show that some familiar contradiction-generating procedures can be seen to be based on vagueness of the relevant theoretical expressions. ;Chapter V deals with the Aufhebung. After an examination of Hegel's own theory of sublation, and an analysis of some textual examples, it is shown that some Aufhebung-procedures can be modelled by certain patterns of argument concerning simple algebraic structures. A few Hegelian concepts, such as "opposition," "unity," "passing over," "reflection," are partially explicated in the process. ;Chapter IV plays a pivotal role in the dissertation. It explains the generation of dialectical contradictions as stemming from syntactic and intensional indeterminacy of the theoretical terms. It is shown that Hegel's conceptual terms have no well-determined sense, so that their senses can be identified in different and possibly inconsistent ways. It is also shown that they can be made to play different syntactic roles, for no rigid determination of their syntactic function is assumed. This, again, may create contradictions. Both kinds of indeterminacy are related to Hegel's borrowing of his conceptual terms from a "natural" philosophical koine. ;Chapter III is an analysis of Hegel's language in the Logic. It tries to determine the grammatical and semantical status of Hegel's conceptual terms and to explicate the Hegelian use of the copula as occurring in certain typical sentential forms. ;The presence of the so-called "dialectical contradictions" is the most evident logico-linguistic peculiarity of Hegel's text. After a discussion of Hegel's theory of contradiction, and of some of its interpretations, it is argued that any satisfactory account of the dialectical method must explain the formation of contradictions on the basis of other logico-linguistic features of Hegel's text. ;Chapter II deals with a few such explanations which have been offered by modern interpreters of Hegel. Use of contemporary analytic concepts in the logical and linguistic analysis of Hegel's text is justified with reference to the Carnapian categories of "explication" and "rational reconstruction." ;The literature on Hegel's dialectic has made important contributions to an understanding of its nature both as a metaphysical theory of reality and as a philosophical attitude towards the human world. However, many recent interpreters agree that no satisfactory progress has been made in understanding dialectic as a method. This dissertation identifies the dialectical method as the specific form of Hegel's philosophical discourse, and tries to bring out its basic logico-linguistic features. The Science of Logic is chosen as the field of inquiry, because of its crucial position among Hegel's mature works. (shrink)

I will discuss those epistemic accounts of truth that say, roughly and at least, that the truth is what all ideally rational people, with maximum evidence, would in the long run come to believe. They have been defended on the grounds that they can solve sceptical problems that traditional accounts cannot surmount, and that they explain the value of truth in ways that traditional (and particularly, minimal) accounts cannot; they have been attacked on the grounds that they collapse into (...) idealism. I show that all these claims are mistaken. The system of statements accepted by an adherent of an epistemic account who also accepts the equivalence scheme is the same as that accepted by an adherent of a traditional account who also accepts a remarkably strong thesis of epistemic optimism. The singling out of one rather than another claim within this system as defining 'true' cannot make as much difference as to imply idealism or refute scepticism. However, it can make all the difference when it is a matter of explaining the value of truth. For a crucial point in such explanation depends on what can be soundly substituted for what in intensional contexts; above all those governed by such verbs as 'know', 'hope', 'believe', 'value'. That is, it depends on what expressions are intensionally equivalent. And one point of singling out one formulation as definitional can be to settle just this. But though some epistemic theorists have deemed ability to explain the value of truth a merit of their account (and lack of this ability a fatal defect of traditional accounts, of minimal accounts in particular), it turns out that minimal accounts of 'true' fit a sound account of our valuing of truth in a way that epistemic accounts do not. In the course of this argument I rebut related positions: e.g. Dummett's, that minimal definitions fail because they cannot account for the point of having a notion of truth, and that an account of the practice of assertion is what would fill this lacuna. I argue to the contrary that if the point of the notion could not be explained on the basis of a traditional definition, it could not be explained at all. (shrink)

The Minimum Description Length principle is the modernformalisation of Occam's razor. It has been extensively and successfullyused in machine learning, especially for noisy and long sources ofdata. However, the MDL principle presents some paradoxes andinconveniences. After discussing all these, we address two of the mostrelevant: lack of explanation and lack of creativity. We present newalternatives to address these problems. The first one, intensionalcomplexity, avoids extensional parts in a description, so distributingcompression ratio in a more even way than the MDL principle. (...) The secondone, information gain, forces that the hypothesis is informative wrt. the evidence, so giving a formaldefinition of what is to discover. (shrink)

J. L. Austin, in "Ifs and Cans," proclaimed the common hope that we soon "may see the birth, through the joint labors of philosophers, grammarians, and numerous other students of language, of a true and comprehensive science of language." The problem has always been with the "joint labors" part. Philosophers have always been willing to issue linguists dictums and linguists have been happy to teach philosophers "plain facts." Austin’s general view of language, and his particular notion of performative utterance, can (...) be found in the writing of J. R. Firth, the most commanding British linguist of Austin’s generation, but Austin never refers to Firth. In the present volume, however, we find clear and exciting evidence of genuinely joint labors on the part of philosophers and linguists. They stem from a summer conference in 1969 rounded out with contributions from notables. To two thick issues of Synthese the editors have added a dazzling piece by Saul Kripke, two substantial pieces by James McCawley and J. R. Ross, a short paper by Paul Ziff, and a reprint of P. F. Strawson’s "Grammar and Philosophy." This is an invaluable book and the best book among the many now available concerning the interaction of linguistics and philosophy: worth the cost, which the contributors attempted to reduce through foregoing royalties. The philosophers in this volume hold, or hold intriguing, the view that the semantics of a natural language can and must, in effect, be a theory of truth for a language in much the manner that Tarski suggested, and provided, for artificial language: the recursive specification of biconditionals in which the left hand gives the structural description of an object language sentence and the right hand, the truth conditions in the metalanguage. In "homophonic" translation this requirement can be trivially satisfied simply by mentioning the sentence on the left that one uses on the right: one makes the requirement non-trivial by forcing enough into the recursive specification so that one captures the native speaker’s implicit semantic competence. In this volume, the "orthodox" Davidsonian program, which takes the syntax of the metalanguage to be standard predicate logic, is ably argued by John Wallace ; Richard Montague, David Lewis, and Jaakko Hintikka would want an intensional logic covering modality and propositional attitudes. The linguists who find this philosophical climate most appealing are called "generative semanticists": McCawley, Ross, George Lakoff and others argue that any proposed semantic rule will eventually prove necessary to syntax too and that, hence, the deepest level of syntactical form will be equivalent to semantic form. Whatever the ultimate fate of this joint program, it leads here to much exciting interaction between linguists and philosophers: linguists who welcome the machinery and conceptual standards of modern logic, and philosophers who try to grasp the specifics of crucial issues in recent linguistic theory. Even if Quine’s doubts, here sketched, and Chomsky’s currently unpublished more technical objections should be well-founded, nonetheless the joint labor will have been very much worthwhile. Aside from this general debate about semantics, there are several papers covering more specific issues. The papers of J. A. Fodor, Terence Parsons, and Ross concern adverbs and the logical form of action sentences; several papers, particularly B. H. Partee’s, examine "Opacity, Coreference, and Pronouns." In all these papers one notes the fulfillment of Austin’s hope that philosophic and linguistic arguments should become intermixed, if not at times properly indistinguishable. Perhaps the most enjoyable and exciting paper stands aside from linguistics: Saul Kripke’s "Naming and Necessity." Kripke here argues quite informally for the separation of analytic, a priori, and necessary that is required for a Kripke style, S5, modal logic with de re modalities. "Gold is a yellow metal," for example, turns out to be contingent, while "Heat is the motion of particles" is necessary but a posteriori ; and that philosopher’s stone of stones, "The morning star is the evening star," is discovered to be necessary but a posteriori.—J.
