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 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 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)

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.

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.

José L. Zalabardo defends a pragmatist account of what grounds the meaning of central semantic discourses--ascriptions of truth, of propositional attitudes, and of meanings. He argues that it is the procedures that regulate acceptance and rejection that give the sentences of these discourses their meanings, and explores the application of the pragmatist template to ethical discourse. The pragmatist approach is presented as an alternative to representationalist accounts of the meaning grounds of declarative sentences, according to which a sentence has (...) the meaning it has as a result of links with the bits of the world that it purports to represent. Zalabardo develops a version of the open-question argument to support the claim that the meaning grounds of the discourses he focuses on cannot receive representationalist accounts. It is generally assumed that a declarative sentence cannot perform the function of representing the world unless it has a representationalist meaning ground. Zalabardo rejects this assumption, arguing that sentences with pragmatist meaning grounds can represent the world in exactly the same sense that sentences with representationalist meaning grounds do. This requires that there are states of affairs that the target sentences represent as obtaining, and Zalabardo develops an account of the nature of the states of affairs that can play this role for sentences with pragmatist meaning grounds. Pragmatist Semantics concludes by developing the suggestion that the meaning grounds of all our representational discourses might be ultimately pragmatist. (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)

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)

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: (1) Academic psychology once had considerable political diversity, but has lost nearly all of it in the last 50 years. (2) 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. (3) 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. (4) 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)

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.

ABSTRACT I argue that some of the central doctrines of Wittgenstein's Tractatus Logico-Philosophicus can be seen as addressing the twin problems of semantic unity and...

An account of predicate reference is presented which attempts to steer a middle course between reductionism, which construes the notion in terms of speakers' inclinations, and {transcendent) realism, which construes the notion in terms of properties. It is first introduced in the context of a discussion of the accounts of length (distance) advanced by Hans Reichenbach, Adolf Grünbaum and Hilary Putnam. A general account of predicate reference is then developed that explains the notion in terms of speakers' inclinations, while rejecting (...) the idea that this explanation should take the form of a reduction. The view is presented as a vindication of extreme nominalism, as it explains predicate reference solely in terms of the notion of qualia introduced by C.I. Lewis and developed by Nelson Goodman, which, it is argued, is definable in terms of speakers' classificatory propensities. Some connections are explored between the position that is presented and the views of Michael Dummett, John McDowell, Mark Johnston and Hilary Putnam, among others. (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)

José L. Zalabardo puts forward a new interpretation of central ideas in Wittgenstein's Tractatus Logico-Philosophicus concerning the structure of reality and our representations of it in thought and language. He presents the picture theory of propositional representation as Wittgenstein's solution to the problems that he had found in Bertrand Russell's theories of judgment. Zalabardo then attributes to Wittgenstein the view that facts and propositions are ultimate indivisible units, not the result of combining their constituents. This is Wittgenstein's solution to (...) the problem of the unity of facts and propositions. Finally, Zalabardo shows that Wittgenstein's views on the analysability of everyday propositions as truth functions of elementary propositions arise from his views on the epistemology of logic: this offers a new perspective on the nature of Tractarian analysis.

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)

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)

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.

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 argue that our procedures for determining whether ascriptions of a predicate represent things as being a certain way are ultimately pragmatic. Pragmatic procedures are not subject to validation by the referential procedure – determining whether there is a property playing the role of its referent. Predicates can represent even if we can't provide an independent identification of its referent. For these predicates, the speakers’ knowledge of how they represent objects as being would have to be construed in terms of (...) the ascription practices they associate with the predicates. The same approach can be applied to semantic predicates, such as ‘is representational’ or ‘refers to’. They can be treated as representational even if we can't provide an independent identification of their referents. The availability of this position undermines accounts of the referents of semantic predicates in naturalistic terms. (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)

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 inPsappha. 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.

En este trabajo se asume: que una teoría factual es un sistema conceptual para representar parcelas deI mundo; que la principal manera de expresar tales sistemas es mediante el lenguaje; y que, consecuentemente, en la comparación de teorías rivales tienen importancia los factores de índole ontosemántica.

Given this perspective, two problems, whieh come up from the acceptance of the incommensurability thesis are analyzed: a) to establish the ontosemantic conditions that give sense to the comparability of incommensurable theories; and b) to consider an ontosemantic picture compatible with the fact that some modifications in a theory are not followd by variance of meaning and reference, while other modifications are.

Embryonic development in a given species is orchestrated by genes regulating growth and differentiation in a stereotyped and conserved manner, resulting in embryos of consistent size and shape. Several signaling pathways, including that of Sonic Hedgehog (SHH), have been implicated in these processes. Recent experiments with Gas1 indicate that it may act as a growth-inducing gene, challenging its previous function as a gene specifically involved in growth arrest. Moreover, GAS1, a GPI-linked membrane protein, can bind SHH, suggesting an interacting link (...) between growth and patterning through SHH and GAS1.(1-4) BioEssays 24:22–26, 2002. © 2002 John Wiley & Sons, Inc.

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)

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.

Aim: The main aim of the present study is to identify which mental footnotes (related to Marx’s and Engels’ Socialism) have more weight in the current cognitive processing of citizens. Background: We used the “Manifesto of the communist party” as the main source of the thoughts from these authors. Method: An experimental design (based on a previous qualitative research) was carried out to test the influence of mental footnotes on the citizens’ decision on the validity of the concepts. Results: The (...) findings point out that there are strong, current, mental footnotes related to the Marx’s and Engels’ concept of bourgeoisie. Conclusions: The Marx’s and Engels’ Philosophy is currently alive, at least, some concepts related to bourgeoisie. People mostly think that the current means of production of modern bourgeoisie were developed in the feudal age, proletariat struggles with bourgeoisie from the beginning, Communism and Socialism are the only political movement that recognized this bourgeoisie-proletariat antagonism and the means of production are nowadays extended to other social classes. The present methodology (from an Experimental Psychology perspective) means a reliable technique to extract the essence of a text and to test the influence of its concepts on human cognitive processing.

I endorse Kripke's (Wittgenstein's) conclusion that the standard of correct application required by the notion of rule-following can only be made sense of in terms of intersubjective agreement. This is not to be taken, as Kripke does, merely as providing assertibility conditions, but rather as a genuine account of what normativity consists in. As Blackburn has pointed out, this result entails that the notion of objective judgment is dependent, in a sense, on the shared inclinations of the members of the (...) community. But since the sceptical paradox admits of no noncommunal solution, it is the inclination-independence of the notion of objective judgment that has to be given up. (shrink)

Es gibt also einen Neu-Fichteanismus. Nun, worin besteht er? Denn die deutliche Zunahme der Anwesenheit Fichtes in der Literatur, so beträchtlich sie auch sein mag, reicht nicht, um einen Begriff zu prägen. Lübbe stellt fest: »Zwischen 1890 und 1900 gibt es zu Fichtes Rechts- und Sozialphilosophie kaum mehr als 10 bemerkenswerte Titel. Zwischen 1900 und 1920 sind es gegen 200«. Das ist zwar viel, aber nicht sehr bedeutsam.

Dort lesen wir nämlich, daß obwohl 1862 keine Monographie über Fichte verfaßt wurde, doch etwas viel Wichtigeres geschah: jenes Jahr stellte einen Wandel in den Beziehungen zwischen Philosophie, Universität und Gesellschaft dar. Diese Veränderungen bringen uns auf die Spur, um begriffliche Transformationen einschätzen zu können. Köhnke faßt wie folgt zusammen. (shrink)

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.

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)
