We begin by highlighting some points related to Kuhn’s later thoughts on the incommensurability thesis and then show to what extent the standard version of the thesis given by the structuralist metatheory allows us to capture Kuhn’s ideas. Our main aim is to establish what constitutes the basis of comparability between incommensurable theories, even in cases of incommensurability with respect to theoretical and non-theoretical terms. We propose that comparability between incommensurable theories requires some connection between their respective ontologies that can (...) be captured by means of an ontological non-reductive relation. At this point, the structuralist notion of “echeloned partial substructure” may be of help. When the incommensurability is very drastic, the existence of ontological connections between the theories involved may only be evident by common terms of their non-characteristic vocabularies. So, this notion of non-characteristic vocabulary becomes relevant in our proposal. (shrink)

In this paper it is assumed that pairs of incommensurable theories are in fact comparable. This point of view leads us to accept that incommensurable theories deal with shared portions of the world. Ontosemantic conditions of comparability between two incommensurable theories are considered along the paper.

¿Es posible compatibilizar una suerte de relativismo epistémico con una defensa de la racionalidad científica? La profesora Pérez Ransanz, además de exponer con claridad la manera en que Thomas S. Kuhn adopta ese doble compromiso, intenta justificar la viabilidad de tal planteamiento. Este objetivo se inscribe en el marco de mostrar que en la reflexión filosófica de Kuhn sobre la ciencia, desde la aparición de La estructura de las revoluciones científica hasta las aportaciones previas a su fallecimiento en 1996, hay (...) continuidad, coherencia y un progresivo enriquecimiento de sus puntos de vista, por encima de pequeñas diferencias que efectivamente pueden encontrarse entre sus diferentes escritos.

Reliabilist accounts of knowledge are widely seen as having the resources for blocking sceptical arguments, since these arguments appear to rely on assumptions about the nature of knowledge that are rendered illegitimate by reliabilist accounts. The goal of this book is to assess the main arguments against the possibility of knowledge, and its conclusions challenge this consensus. The book articulates and defends a theory of knowledge that belongs firmly in the truth-tracking tradition, and argues that although the theory has the (...) resources for blocking the main standard lines of sceptical reasoning, there is a sceptical argument against which the theory offers no defence, as it doesn’t rely on any assumptions that the theory would render illegitimate. The book ends with the suggestion that the problem might have a metaphysical solution—that although the sceptical argument may make no illegitimate epistemological assumptions, it does rest on a questionable account of the nature of cognition.

Propaganda has been historically used for the benefit of certain social groups faced up to another. This propaganda is not always ethical at all. It is based on misconceptions, lies, and fallacies. We have analyzed (by using an experimental Psychology task) the presence and cognitive weight of certain mental footnotes and their influence on the Reasoning of Hispanic-Americans (Ecuadorian). These mental footnotes have been extracted from the classical work “A brief account of the destruction of the Indies” of Bartolomé de (...) las Casas in 1552. The most relevant and significant finding of this study is the clear evidence that nowadays we can still find these historical falsehoods in the current cognitive system of Ecuadorian people which are product of a well-planned and maliciously orchestrated propaganda. We conclude that all the contents of the Spanish black legend are the consequences of the aspirations of some social sectors to boycott the Spanish culture. (shrink)

In Wittgenstein on Rules and Private Language, Saul Kripke rejects some of the most popular accounts of what meaning facts consist in on the grounds that they fail to accommodate the normative character of meaning. I argue that a widespread interpretation of Kripke's argument is incorrect. I contend that the argument does not rest on the contrast between descriptive and normative facts, but on the thought that speakers' uses of linguistic expressions have to be justified. I suggest that the line (...) of reasoning that I attribute to Kripke can be seen as putting pressure on the idea that predicate satisfaction is to be explained in terms of a relation between predicates and properties.

Understanding compositional practices is a major goal of musicology and music theory. Compositional practices have been traditionally viewed as disembodied and idiosyncratic. This view makes it hard to integrate musical creativity into our understanding of the general cognitive processes underlying meaning construction. To overcome this unnecessary isolation of musical composition from cognitive science, in this conceptual analysis, we approach compositional processes with the analytic tools of blending theory, material anchoring, and enaction. Our case study is Iannis Xenakis’ use of sieves (...) for distributing rhythmic patterns in Psappha. Though disregarded in previous accounts, the timeline and the gearwheel provide crucial conceptual templates for anchoring Xenakis’ idea of time for this score. This case study of conceptual integration templates for temporal representation seeks to gain insight into musical creativity, embodiment, and blending, especially into how virtual interactions with material structures facilitate the construction of complex meanings.

The subject matter of this paper is the view that it is correct, in an absolute sense, to believe a proposition just in case the proposition is true. I take issue with arguments in support of this view put forward by Nishi Shah and David Velleman.

The paper argues against Sosa’s claim that sensitivity cannot be differentially supported over safety as the right requirement for knowledge. Its main contention is that, although all sensitive beliefs that should be counted as knowledge are also safe, some insensitive true beliefs that shouldn’t be counted as knowledge are nevertheless safe.

In the recent literature on confirmation there are two leading approaches to the provision of a probabilistic measure of the degree to which a hypothesis is confirmed by evidence. The first is to construe the degree to which evidence E confirms hypothesis H as a function that is directly proportional to p and inversely proportional to p . I shall refer to this as the probability approach. The second approach construes the notion as a function that is directly proportional to (...) the true-positive rate – the probability of the evidence if the hypothesis is true, p – and inversely proportional to the false-positive rate – the probability of the evidence if the hypothesis is false, p . These reverse conditional probabilities – of the evidence on the truth or falsehood of the hypothesis – are sometimes known as likelihoods. I shall refer to the approach to confirmation that uses them as the likelihood approach.For each of these approaches, there are two obvious options as to how to define the confirmation function. The first is to define it as the difference between the magnitude that is treated as increasing confirmation or p ) and the magnitude that is treated as decreasing confirmation or p ). The second is to define confirmation as the quotient of these two magnitudes.This yields four different measures of confirmation, represented in the following table: Differences RatiosProbabilities PD = p – p1 PR = Graphic2Likelihoods LD = p – p3 LR = Graphic4All these measures agree on whether or not E provides some support for H. Intuitively, we want to say that E provides some support for H just in case learning that E is true would make us assign a higher probability to H, i.e. when p(H …. (shrink)

The paper deals with a version of the principle that a belief source can be a knowledge source only if the subject knows that it is reliable. I argue that the principle can be saved from the main objections that motivate its widespread rejection: the claim that it leads to skepticism, the claim that it forces us to accept counterintuitive knowledge ascriptions and the claim that it is incompatible with reliabilist accounts of knowledge. I argue that naturalist epistemologists should reject (...) these claims. I introduce my treatment of the principle by considering the analogous situation posed by the closure principle. (shrink)

Critical studies in higher education often embrace the ideas of the slowness movement to address time pressure. However, this desirable horizon presents some limitations. On the one hand, by emphasizing solutions at the individual level, boosting slowness may promote tactics incapable of producing changes to the underlying structural dynamics of time pressure. On the other hand, approaches based on slowness may also inadvertently foster a form of ethical paternalism within the context of ethical pluralism by prescribing substantive models of practice (...) ultimately based on ‘do this quickly or do it slowly.’ This theoretical research moves away from the temporal paradigm to that of the way of relating. Building upon the ethical concept of resonance, the approach focuses on a formal critique of the current socioeconomic and ethical dynamics of social acceleration, growth, and innovation that can contribute to projecting non-alienated relationships in higher education.

Psychologists have demonstrated the value of diversity – particularly diversity of viewpoints – for enhancing creativity, discovery, and problem solving. But one key type of viewpoint diversity is lacking in academic psychology in general and social psychology in particular: political diversity. This article reviews the available evidence and finds support for four claims: Academic psychology once had considerable political diversity, but has lost nearly all of it in the last 50 years. This lack of political diversity can undermine the validity (...) of social psychological science via mechanisms such as the embedding of liberal values into research questions and methods, steering researchers away from important but politically unpalatable research topics, and producing conclusions that mischaracterize liberals and conservatives alike. Increased political diversity would improve social psychological science by reducing the impact of bias mechanisms such as confirmation bias, and by empowering dissenting minorities to improve the quality of the majority's thinking. The underrepresentation of non-liberals in social psychology is most likely due to a combination of self-selection, hostile climate, and discrimination. We close with recommendations for increasing political diversity in social psychology. (shrink)

James Shaw has written an excellent book on Wittgenstein’s rule-following considerations. It manages to provide fresh perspectives on a topic on which it seemed.

I discuss the account of logical consequence advanced in Wittgenstein's Tractatus. I argue that the role that elementary propositions are meant to play in this account can be used to explain two remarkable features that Wittgenstein ascribes to them: that they are logically independent from one another and that their components refer to simple objects. I end with a proposal as to how to understand Wittgenstein's claim that all propositions can be analysed as truth functions of elementary propositions.

I take issue with Robert Brandom’s claim that on an analysis of knowledge based on objective probabilities it is not possible to provide a stable answer to the question whether a belief has the status of knowledge. I argue that the version of the problem of generality developed by Brandom doesn’t undermine a truth-tracking account of noninferential knowledge that construes truth-tacking in terms of conditional probabilities. I then consider Sherrilyn Roush’s claim that an account of knowledge based on probabilistic tracking (...) faces a version of the problem of generality. I argue that the problems she raises are specific to her account, and do not affect the version of the view that I have advanced. I then consider Brandom’s argument that the cases that motivate reliabilist epistemologies are in principle exceptional. I argue that he has failed to make a cogent case for this claim. I close with the suggestion that the representationalist approach to knowledge that I endorse and Brandom rejects is in principle compatible with the kind of pragmatist approach to belief and truth that both Brandom and I endorse.

To the sceptic's contention that I don't know that I have hands because I don't know that there is an external world, the Moorean replies that I know that there is an external world because I know that I have hands. Crispin Wright has argued that the Moorean move is illegitimate, and has tried to block it by limiting the applicability of the principle of the transmission of knowledge by inference—the principle that recognising the validity of an inference from known (...) premises generates knowledge of the conclusion. I argue that, in the presence of some plausible assumptions, blocking the Moorean move does not require limiting the applicability of the transmission principle. Then I argue against Jim Pryor's contention that the Moorean argument transmits evidential support from its premises to its conclusion. (shrink)

The paper deals with the interpretation of Wittgenstein's views on the power of occurrent mental states to sort objects or states of affairs as in accord or in conflict with them, as presented in the rule-following passages of the Philosophical Investigations. I shall argue first that the readings advanced by Saul Kripke and John McDowell fail to provide a satisfactory construal of Wittgenstein's treatment of a platonist account of this phenomenon, according to which the sorting power of occurrent mental states (...) is to be explained by reference to the mind's ability to grasp universals. I contend that the argument that Kripke extracts from Wittgenstein's discussion doesn't succeed in undermining the platonist position. Then I argue that McDowell's reading exhibits a more serious shortcoming: the position that he ascribes to Wittgenstein is indistinguishable from the platonist account. Then I put forward a proposal as to how to articulate the relationship between Wittgenstein's views and the platonist position. (shrink)

I provide a construal of the epistemic regress problem and I take issue with the contention that a foundationalist solution is incompatible with an internalist account of warrant. I sketch a foundationalist solution to the regress problem that respects a plausible version of internalism. I end with the suggestion that the strategy that I have presented is not available only to the traditional versions of foundationalism that ascribe foundational status to experiential beliefs. It can also be used to generate a (...) version of internalist foundationalism based on reliabilist principles. (shrink)

In this paper I assess the two central ingredients of Laurence BonJour’s position on empirical knowledge that have survived the transition from his earlier coherentist views to his current endorsement of the doctrine of the given: his construal of the problem of the epistemic regress and his rejection of an internalist solution to the problem. The bulk of the paper is devoted to a critical assessment of BonJour’s arguments against externalism. I argue that they fail to put real pressure on (...) externalism, as they rely on a highly questionable conception of epistemic rationality and responsibility. Then, more briefly, I take issue with BonJour’s endorsement of the irrelevance thesis—the claim that even if externalism were true it would not offer a satisfactory solution to the epistemic regress problem. I contend that he is not entitled to subscribe this thesis unless he is prepared to abandon his construal of the problem. (shrink)

An introduction to the basic concepts and results of contemporary logic, including a discussion of the basic mathematical tools needed to master the technical aspects of the subject.

I use some ideas of Keith DeRose's to develop an (invariantist!) account of why sceptical reasoning doesn't show that I don't know that I'm not a brain in a vat. I argue that knowledge is subject to the risk-of-error constraint: a true belief won’t have the status of knowledge if there is a substantial risk of the belief being in error that hasn’t been brought under control. When a substantial risk of error is present (i.e. beliefs in propositions that are (...) false in nearby worlds), satisfying the constraint requires bringing the risk under control. This is achieved either by sensitivity, i.e. you wouldn’t have the belief if it were false, or by identifying evidence for the proposition. However, when the risk of error is not substantial (i.e. beliefs in propositions that are not false in nearby worlds), the constraint is satisfied by default. My belief that I am not a brain in a vat is insensitive and I have no evidence for it, but since it is not false in nearby worlds, it satisfies the constraint by default. (shrink)

According to actualism, modal reality is constructed out of valuations (combinations of truth values for all propositions). According to possibilism, modal reality consists in a set of possible worlds, conceived as independent objects that assign truth values to propositions. According to possibilism, accounts of modal reality can intelligibly disagree with each other even if they agree on which valuations are contained in modal reality. According to actualism, these disagreements (possibilist disagreements) are completely unintelligible. An essentially actualist semantics for modal propositional (...) logic specifies which sets of valuations are compatible with the meanings of the truth-functional connectives and modal operators without drawing on formal resources that would enable us to represent possibilist disagreements. The paper discusses the availability of an essentially actualist semantics for modal propositional logic. I argue that the standard Kripkean semantics is not essentially actualist and that other extant approaches also fail to provide a satisfactory essentially actualist semantics. I end by describing an essentialist actualist semantics for modal propositional logic. (shrink)

Many interpreters of the Tractatus accept that the book endorses an argument for simples based on the reflection that, since complexes exist only contingently, if names referred to complexes the propositions in which they figure would lack sense if their referents went out of existence. More specifically, most interpreters read 2.0211-2.0212 as putting forward this argument. My main goal in this paper is to attack this reading and to put forward an alternative. I argue that there is no good reason (...) for thinking that the Tractatus advances this argument. I argue that 2.0211-2, in particular, should not be read in this way, and put forward an alternative reading of the passage. (shrink)

The paper addresses the question whether semantic naturalism is undermined by the thought that semantic concepts are normative.

Information theoretic semantics proposes to construe predicate reference in terms of nomological relations between distal properties and properties of representational mental events. Research on the model has largely concentrated on the problem of choosing the nomological relation in terms of which distal properties are to be singled out. I argue that, in addition to this, an information theoretic account has to provide a specification of which properties of representational mental events will play a role in determining reference, qua bearers of (...) nomological relations. I contend that this task poses a serious additional challenge to the viability of the model. (shrink)

The paper develops an account of semantic notions which occupies a middle ground between antirealism and traditional forms of realism, using some ideas from the work of John McDowell. The position is based on a contrast between two points of view from which we might attempt to characterize our linguistic practices from the cosmic exile s point of view and from the midst of language as a going concern. The contrast is drawn in terms of whether our characterization of our (...) linguistic practices is taken to result from engagement in the very same practices that we are trying to characterize. The position takes realism to be correct when understood as an account from the internal perspective, but incorrect when taken as an account from the external perspective. However, the intelligibility of the question as to what our practices would look like from the cosmic exile s point of view is presented as problematic. (shrink)

The paper deals with our ability to classify objects as being of a certain kind on the basis of information provided by the senses (empirical classification) and to ascribe empirical predicates to objects on the basis of these classificatory verdicts (empirical predication). I consider, first, the project of construing the episodes in which this ability is exercised as involving universals. I argue that this construal faces epistemological problems concerning our access to the universals that it invokes. I present the empiricist (...) strategy for dealing with these problems by appeal to sensory qualities, and argue that it rests on a mistake. Then I turn to sketching an account of our faculty of empirical classification and predication which doesn't invoke universals. The account takes as its starting point the nominalist construal of sense experience to be found in the work of C. I. Lewis and Nelson Goodman. I argue that this construal has the resources for explaining some of the central features of the practice of empirical predication. There are those who feel that our ability to understand general terms ... would be inexplicable unless there were universals as objects of apprehension. And there are those who fail to detect, in such appeal to a realm of entities over and above the concrete objects in space and time, any explanatory value. W. V. O.

I offer an interpretation of Wittgenstein's claim that Russell's theory of judgment fails to show that it's not possible to judge nonsense.

David Lewis has argued that we cannot identify the fundamental properties. It is generally accepted that we can resist Lewis's conclusion if we are prepared to accept a structuralist account of fundamental properties, according to which their causal/nomological role is essential to their identity. I argue, to the contrary, that a structuralist construal of fundamental properties does not sustain a successful independent strategy for resisting Lewis's conclusion. The structuralist can vindicate our ability to identify fundamental properties only if she accepts (...) epistemic principles that suffice for blocking Lewis's conclusion even if fundamental properties are not construed along structuralist lines.
