It is widely believed that some puzzling and provocative remarks that Frege makes in his late writings indicate he rejected independence arguments in geometry, particularly arguments for the independence of the parallels axiom. I show that this is mistaken: Frege distinguished two approaches to independence arguments and his puzzling remarks apply only to one of them. Not only did Frege not reject independence arguments across the board, but also he had an interesting positive proposal about the logical structure of correct (...) independence arguments, deriving from the geometrical principle of duality and the associated idea of substitution invariance. The discussion also serves as a useful focal point for independently interesting details of Frege's mathematical environment. This feeds into a currently active scholarly debate because Frege's supposed attitude to independence arguments has been taken to support a widely accepted thesis (proposed by Ricketts among others) concerning Frege's attitude toward metatheory in general. I show that this thesis gains no support from Frege's puzzling remarks about independence arguments. (shrink)

In this paper I examine the question of logic’s normative status in the light of Carnap’s Principle of Tolerance. I begin by contrasting Carnap’s conception of the normativity of logic with that of his teacher, Frege. I identify two core features of Frege’s position: first, the normative force of the logical laws is grounded in their descriptive adequacy; second, norms implied by logic are constitutive for thinking as such. While Carnap breaks with Frege’s absolutism about logic and hence with the (...) notion that any system of logic should have a privileged claim to correctness, I argue that there is a sense in which Carnap’s framework-relative conception of logical norms has a constitutive role to play: though they are not constitutive for the conceptual activity for thinking, they do nevertheless set the ground rules that make certain forms of scientific inquiry possible in the first place. I conclude that Carnap’s principle of tolerance is tamer than one might have thought and that, despite remaining differences, Frege’s and Carnap’s conceptions of logic have more in common than one might have thought.

Since the famous debate between Russell (Mind 14: 479–493, 1905, Mind 66: 385–389, 1957) and Strawson (Mind 59: 320–344, 1950; Introduction to logical theory, 1952; Theoria, 30: 96–118, 1964) linguistic intuitions about truth values have been considered notoriously unreliable as a guide to the semantics of definite descriptions. As a result, most existing semantic analyses of definites leave a large number of intuitions unexplained. In this paper, I explore the nature of the relationship between truth value intuitions and non-referring definites. (...) Inspired by comments in Strawson (Introduction to logical theory, 1964), I argue that given certain systematic considerations, one can provide a structured explanation of conflicting intuitions. I show that the intuitions of falsity, which proponents of a Russellian analysis often appeal to, result from evaluating sentences in relation to specific questions in context. This is shown by developing a method for predicting when sentences containing non-referring definites elicit intuitions of falsity. My proposed analysis draws importantly on Roberts (in: Yoon & Kathol (eds.) OSU working papers in Linguistics: vol. 49: Papers in Semantics 1998; in: Horn & Ward (eds.) Handbook of pragmatics, 2004) and recent research in the semantics and pragmatics of focus. (shrink)

Two general principles have played a crucial role in the recent debate on concepts. On the one hand, we want to allow different subjects to have the same concepts, thus accounting for concept publicity: concepts are ‘the sort of thing that people can, and do, share’. On the other hand, a subject who finds herself in a so-called ‘Frege case’ appears to have different concepts for the same object: for instance, Lois Lane has two distinct concepts SUPERMAN and CLARK KENT (...) which refer to the same person. Several theories have tried to meet both of these constraints at the same time. But should we really try to satisfy both principles? This paper will argue that the traditional project of fulfilling these two constraints has been a misguided one. Through a variation on classic identity mistake cases, I will show that our two desiderata are inconsistent: it would thus be impossible to incorporate both of them in our best theory of concepts.

In an unpublished manuscript of 1914 titled ‘Logic in mathematics’, Gottlob Frege offered a rich account of the paradox of analysis. I argue that Frege there claims that the explicandum and explicans of a successful analysis express the same sense and that he furthermore appreciated that this requires that one cannot conclude that two sentences differ in sense simply because it is possible for a (minimally) competent speaker to accept one without accepting the other. I claim that this is shown (...) by Frege’s suggestive remarks about a cloudy grasp of a sense. I then argue that this fact calls into question a key assumption behind Frege’s master argument for the sense/reference distinction. (shrink)

How many senses can a given name have, with its reference held fixed? One, more than one? One answer that most would agree to is that sense is unique for each utterance of a name, that is, that a name can have no more than one sense on any given occasion. But is sense unique in any stronger sense than this? The answer that is typically attributed to Frege is that there is not, that, as Tyler Burge puts it, 1 (...) Frege “treats proper names as having different senses while applying to the same person.” There are a number of possibilities for the locus of this multiplicity of sense; the following remark by Ruth Marcus indicates the possibilities: “the sense of a term is whatever is grasped or understood by a speaker on a particular occasion of use and may vary from occasion to occasion as well as from speaker to speaker.”2 Of the views canvassed by Marcus, we can draw out a more conservative one, and one more extreme. On the more conservative view, Frege is holding that sense may vary from speaker to speaker; on the more extreme view, Frege holds not only this, but that sense may vary from context to context. Endorsements of the two views are not hard to find. For example, typical sorts of endorsement of the conservative view are found in Harold Noonan’s remark that “different senses [are] associated with the name ‘Aris-. (shrink)

Os demonstrativos foram considerados tradicionalmente como expressões referenciais. É o que encontramos na história da filosofia desde o início da tradição gramatical ocidental que sempre tratou os demonstrativos como pronomes. A maior provocação no livro de King consiste precisamente em romper com essa tradição ao apresentar os demonstrativos complexos (“esta mesa”, “aquele homem” etc.) como termos quantificados (e, portanto, termos não-referenciais). King apóia seu tratamento sobre exemplos escolhidos que parecem favorecer sua tese, como “aquele arquiteto que construiu essas pirâmides era (...) um gênio”, quando o locutor da frase não tem nenhum alvo referencial em mente e não pode apontar para ninguém no contexto da enunciação. Mostrarei: 1) que o tratamento de King representa uma tremenda ruptura com a tradição e desconsidera as intuições de gerações e gerações de lingüistas e filósofos da linguagem; 2) que King apóia sua tese em evidências de natureza puramente sintática sem discutir metodologicamente o peso que devemos atribuir a essas evidências sintáticas nas discussões de semântica; 3) que King não leva em conta todos os dados disponíveis, forçando os dados por ele recolhidos a entrar numa mesma teoria unificada, mas, para isso, paga um preço alto: uma redundância inaceitável na semântica das expressões demonstrativas simples.

Gilbert Ryle’s distinction between knowledge-how and knowledge-that emerged from his criticism of the “intellectualist legend” that to do something intelligently is “to do a bit of theory and then to do a bit of practice,” and became a philosophical commonplace in the second half of the last century. In this century Jason Stanley has attacked Ryle’s distinction, arguing that “knowing-how is a species of knowing-that,” and accusing Ryle of setting up a straw man in his critique of “intellectualism.” Examining the (...) use of the terms “intellectualism” and “anti-intellectualism” in the first half of the 20th century, in a wide-ranging debate in the social sciences as well as in philosophy, I show that Ryle was not criticizing a straw man, but a live historical position. In the context of this controversy, Ryle’s position represents a third way between “intellectualism” and “anti-intellectualism,” an option that has largely gone missing in the 21st century discussion. This argument illustrates how history can inform the history of philosophy, and how the history of philosophy can inform contemporary philosophical inquiry. (shrink)

What follows is talky—I skitter across a number of difficult topics much too quickly and with little attempt to defend what I say. I may be able to add some defense later in discussion, but I don't promise anything much and certainly nothing fancy. I am still very much in the process of thinking about these topics, and I aim to do no more than to perhaps nudge you to think about them too.By "poetry" in what follows, I typically mean (...) "lyric poetry." There are poems and poems and poems, and the dactyls make a difference, as do many other features internal to poetry. I will also say upfront that I have no working definition of "lyric poetry." I also have no working definition of "philosophy," although I will be... (shrink)

Gottlob Frege may be considered as the first intellectual giant in thePhilosophy of Language. He was the first to raise the issue ofmeaning by formulating an organized theory of meaning for a part ofnatural language as the theory of meaning is at the core of philosophy of language. He emphasizes that the meaning of a sentence directly depends on the meaning of its constituent parts. That is why he has to dissect the internal structure of a sentence or complex expressions (...) provided by a logical syntax, while the truth value of such sentences may be revealed by logical semantics which can be put forward by treating these sentences as a whole.

Journal of Philosophy of Education When reliability and validity were introduced as validation criteria for empirical research in the human sciences, quantitative research methods prevailed, and theory of science relied on neopositivism (Vienna Circle) or postpositivism (scientific realism). Within this worldview, notions of reliability and validity as criteria of scientific goodness were introduced. Reliability and validity were associated with the correspondence theory of truth, which is mostly ill-suited to the needs of qualitative research. For that reason, qualitative research must look (...) for other kinds of validation criteria. The article elaborates the problems arising when the correspondence theory of truth is used as an ultimate criterion in evaluating qualitative research and proposes Heidegger's hermeneutical or alethetical idea of truth as a more suitable approach.

This paper is about what is distinctive about first-person beliefs. I discuss several sets of puzzling cases of first-person belief. The first focus on the relation between belief and action, while the second focus on the relation of belief to subjectivity. I argue that in the absence of an explanation of the dispositional difference, individuating such beliefs more finely than truth conditions merely marks the difference. I argue that the puzzles reveal a difference in the ways that I am disposed (...) to revise my beliefs about myself. This point develops the insight that Anscombe and others had that those of an agent's beliefs about himself that manifest that special self-consciousness are not based on observation, testimony or inference. The puzzles show that this kind of self-consciousness involves, not a special kind of belief or even a special kind of self-reference, but a special kind of belief revision policy. (shrink)

I want to promote what I shall call ‘the identity theory of truth’. I suggest that other accounts put forward as theories of truth are genuine rivals to it, but are unacceptable. A certain conception of thinkables belongs with the identity theory’s conception of truth. I introduce these conceptions in Part I, by reference to John McDowell’s Mind and World; and I show why they have a place in an identity theory, which I introduce by reference to Frege. In Part (...) II, I elaborate on the conception of thinkables, with a view to demonstrating that the identity theory’s conception of truth is defensible. Part III is concerned with the theory’s relation to some recent work on the concept of truth: I hope to show that the identity theorist not only has a defensible conception of truth, but also, in the present state of play, has appropriate ambitions.

I open my eyes and see that the lemon before me is yellow. States like this—states of seeing that $p$ —appear to be visual perceptual states, in some sense. They also appear to be propositional attitudes (and so states with propositional representational contents). It might seem, then, like a view of perceptual experience on which experiences have propositional representational contents—a Propositional View—has to be the correct sort of view for states of seeing that $p$ . And thus we can’t sustain (...) fully general non-Propositional but Representational, or Relational Views of experience. But despite what we might initially be inclined to think when reflecting upon the apparent features of states of seeing that $p$ , a non-propositional view of seeing that $p$ is, I argue, perfectly intelligible.

Abstract: A theory of time is a theory of the nature of temporal reality, and temporal reality determines the truth-value of temporal sentences. Therefore it is reasonable to ask how a theory of time can account for the way the truth of temporal sentences is determined. This poses certain challenges for both the A theory and the B theory of time. In this paper, I outline an account of temporal sentences. The key feature of the account is that the primary (...) bearers of truth-values are not utterances, but sentences evaluated with respect to a time. I argue that unlike other views, the present proposal can meet the challenges faced both by the A and the B theory. (shrink)

A singular thought can be characterized as a thought which is directed at just one object. The term ‘thought’ can apply to episodes of thinking, or to the content of the episode (what is thought). This paper argues that episodes of thinking can be just as singular, in the above sense, when they are directed at things that do not exist as when they are directed at things that do exist. In this sense, then, singular thoughts are not object-dependent.

This paper explores a variety of different versions of the thesis that natural language is involved in human thinking. It distinguishes amongst strong and weak forms of this thesis, dismissing some as implausibly strong and others as uninterestingly weak. Strong forms dismissed include the view that language is conceptually necessary for thought (endorsed by many philosophers) and the view that language is _de facto_ the medium of all human conceptual thinking (endorsed by many philosophers and social scientists). Weak forms include (...) the view that language is necessary for the acquisition of many human concepts, and the view that language can serve to scaffold human thought processes. The paper also discusses the thesis that language may be the medium of _conscious_ propositional thinking, but argues that this cannot be its most fundamental cognitive role. The idea is then proposed that natural language is the medium for non-domain-specific thinking, serving to integrate the outputs of a variety of domain-specific conceptual faculties (or central-cognitive ‘quasi-modules’). Recent experimental evidence in support of this idea is reviewed, and the implications of the idea are discussed, especially for our conception of the architecture of human cognition. Finally, some further kinds of evidence which might serve to corroborate or refute the hypothesis are mentioned. The overall goal of the paper is to review a wide variety of accounts of the cognitive function of natural language, integrating a number of different kinds of evidence and theoretical consideration in order to propose and elaborate the most plausible candidate.

The thesis of Ineffability has it that no proposition can be fully expressed by a sentence, this meaning that no sentence-type, or even sentence-token whose indexicality and ambiguities have been resolved, can fully encode a proposition. The thesis of the propositionality of thoughts has it that thoughts are propositional. An implication of the joint endorsement of these two theses is that thoughts are ineffable. The aim of this paper is to argue that this is not the case: there are effable (...) thoughts, and we can even safely say that, generally, thoughts are effable. In order to defend this insight, I first counter the thesis of the propositionality of thought by bringing some counterexamples to it, which amount to cases of non-fully propositional thought. I then argue that, if thoughts can be and often are non-fully propositional, they can be expressed by sentences that fail to fully express a proposition. I also show that the propositional thoughts that we can entertain are after all effable (in a suitable, relevant sense) and resist some alleged examples of insurmountable ineffability. (shrink)

The Effability thesis has it that all propositions can be encoded by a sentence. By contrast, the Ineffability thesis has it that no proposition can be encoded by a sentence. In this article, I undermine an important motivation for the Ineffability thesis and advance a proposal concerning what is effable and what is not. My strategy will be as follows: First, I'll note that the Ineffability thesis assumes that propositions/thoughts are determinate. I'll point out that propositions/thoughts qua the things we (...) believe and mean by our utterances may in fact be indeterminate with regard to, for instance, mental predication and mental reference. I'll then propose a “Gradable Effability”: propositions/thoughts are more or less determinate according to the aims, interests, available information of thinkers, and sentences too encode propositions depending on the aims, interests, available information in the speakers' conversational setting.

The liar paradox can be shown semantically defective if we distinguish the /sentence/ ''snow is white' is true' from the /string/ that constitutes it. This paper develops the String-to-Sentence Theory of Truth---for short, String Theory---according to which, while the /string/ contains the string 'true', the /sentence/ is merely 'snow is white', which contains no such occurrence: more generally, a string like 'S is true' constitutes, relative to an assessor, the sentence which, to the assessor, means the same as S. So (...) suppose we attempt to define a singular term 'L' referring to the sentence 'not: L is true'. Relative to an assessor, 'L' refers to the sentence negating the assessor's sentence meaning the same as the referent of 'L'. So the referent of 'L' means the same as its negation. But no sentence means the same as its negation, so 'L' does not refer. The act of naming with which the liar paradox commences is semantically defective; so there can be no liar paradox. (shrink)

In this paper, I address the idea that certain sentences suffer from what is generally called semantic unspecificity: their meaning is determinate, but their truth conditions are not. While there tends to be agreement on the idea that semantic unspecificity differs from phenomena such as ambiguity and vagueness, some theorists have defended an account which traces it to indexicality, broadly construed. Some authors have tried to vindicate the distinction between unspecificity and indexicality and, in this paper, I pursue the same (...) cause, but with a critical stance towards previously employed strategies. I urge that the central argument employed by Sainsbury to trace this difference fails suitably to set unspecificity apart from indexicality and I propose a new argument, which helps to trace this distinction more perspicuously. The argument is based on embeddings of indexical and unspecific expressions within modal operators and on the ways in which the truth conditions of utterances of the resulting, complex expressions are thereby affected.

This dissertation is on infinite regress arguments in philosophy. Its main goals are to explain what such arguments from many distinct philosophical debates have in common, and to provide guidelines for using and evaluating them. Two theories are reviewed: the Paradox Theory and the Failure Theory. According to the Paradox Theory, infinite regress arguments can be used to refute an existentially or universally quantified statement (e.g. to refute the statement that at least one discussion is settled, or the statement that (...) discussions are settled only if there is an agreed-upon criterion to settle them). According to the Failure Theory, infinite regress arguments can be used to demonstrate that a certain solution fails to solve an existentially or universally quantified problem (e.g. to demonstrate that a certain solution fails to settle all discussions, or that it fails to settle even one discussion). In the literature, the Paradox Theory is fairly well-developed, and this dissertation provides the Failure Theory with the same tools. (shrink)

The Access principle places an epistemic restriction on our obligations. This principle falls prey to the ‘Shirker Problem’, namely that shirkers could evade their obligations by evading certain epistemic circumstances. To block this problem, it has been suggested that shirkers have the obligation to learn their obligations. This solution yields a regress, yet it is controversial what the moral of the regress actually is. The aim of this paper is two-fold. First, I spell out this intricate dispute. Second, on the (...) basis of my analyses I propose solutions to the Shirker Problem. (shrink)

Brentano’s account of what he called intentionale Inexistenz — what we now call intentionality — is without question one of the most important parts of his philosophy, and one of the most influential ideas in late 19th-century philosophy. Here I will explain how this idea figures in Brentano’s central text, Psychology from an Empirical Standpoint (Brentano 1995a). I will then briefly explain how Brentano’s ideas about intentionality evolved after the first publication of this work in 1874, and how they were (...) then misinterpreted by some influential analytic philosophers.

We examine how Frege’s contrast between identity judgments of the forms “a=a” vs. “a=b” would fare in the special case where ‘a’ and ‘b’ are complex mental representations, and ‘a’ stands for an introspected ‘I’-thought. We first argue that the Fregean treatment of I-thoughts entails that they are what we call “one-shot thoughts”: they can only be thought once. This has the surprising consequence that no instance of the “a=a” form of judgment in this specific case comes out true, let (...) alone a priori true. This further reinforces Glezakos’s objections against the set-up of Frege’s puzzle, while also raising what we think is an acute problem for Fregeans, insofar as I-thought (and indexical thinking more generally), understood in their way, turns out to be incompatible with some basic features of rationality.

Jennifer Hornsby’s 1997 paper, ‘Truth: The Identity Theory’, has been highly influential in making the identity theory of truth a viable option in contemporary philosophy. In this introduction and commentary I focus on what distinguishes her theory and its methodology from the correspondence theory and the ‘substantivist’ methodology, and on other issues that have not been widely discussed in earlier commentaries yet are central to the current debate on truth.
