Frege: Sinn and Bedeutung

E.E.C. Jones’s early logical writings have recently been rescued from obscurity and it has been claimed that, in her works dating from the 1890s, she anticipated Frege’s distinction between sense and reference. This claim is challenged on the ground that it is based on a common but inadequate reading of Frege, which runs together his concept/object and sense/reference distinctions. It is admitted that a case can be made for Jones having anticipated something very like Frege’s analysis of categorical propositions, and (...) that she offered a sound rebuttal of Russell’s objection to Frege’s account of the informativeness of identity statements. However, these significant achievements should not be misrepresented as an anticipation of Frege on sense and reference, a claim that encourages a defective reading of both philosophers. (shrink)

Este artigo tem como objetivo expor e discutir as concepções de Gottlob Frege sobre os conceitos de “sentido” e “referência” e como, por meio destes, se deu a contribuição do filósofo ao que hoje chamamos filosofia da linguagem. Entretanto, vários estudiosos não consideram Frege um autêntico filósofo da linguagem, alguns de seus escritos representam, historicamente, enorme influência nesse ramo da filosofia contemporânea, pois tentam solucionar certos problemas da linguagem. Serão analisados principalmente o célebre artigo “Sobre Sentido e Referência” bem como (...) alguns de seus escritos que se ocupam, ainda que de modo secundário, sobre ambos os conceitos. (shrink)

In a letter of 1891, Frege drew a diagram to illustrate his logical ontology. We observe that it omits features that play an important role in his thought on the matter, propose an extension of the diagram to include them, and compare with a diagram of the ontology of current first-order logic.

This dissertation is about the structure of thought. Following Gottlob Frege, I define a thought as the sort of content relevant to determining whether an assertion is true or false. The historical component of the dissertation involves interpreting Frege’s actual views on the structure of thought. I argue that Frege did not think that a thought has a unique decomposition into its component senses, but rather the same thought can be decomposed into senses in a variety of distinct ways. I (...) extend Frege’s position and use it to develop an account of the hierarchy of senses, the senses expressed by indexicals and demonstratives, and the distinction between logical and non-logical structure. I also discuss various connections with the nature of meta-representation, our capacity for reflective judgment, some aspects of the structure of conscious experience, the way we perceive regions of space and durations of time, and our conscious awareness of our own perceptions and events of thinking.

This paper argues for the centrality of expression for the project of phenomenology. It shows, first, that the concept of expression grows out of the debate with Frege concerning meaning that led to Husserl’s distinct phenomenological project. Specifically, expression is Husserl’s first attempt to more rigorously define ‘sense’ as the essential connection between subjective acts of meaning and ‘objective’ meanings. This account of expression is then taken up in Husserl’s later work on spirit, which thereby makes expression central to Husserl’s (...) entire analysis of the lifeworld. Insofar as Husserl saw phenomenology growing out of his dispute with Frege on meaning, and working toward the ability to clarify the sense of all scientific knowledge, expression names the promise inherent to phenomenology itself, that which defines the very project of phenomenology.

Dieses Buch enthält in einer historisch-kritischen Edition die Texte, die es in seinem Hauptteil kommentiert: Das Vorwort (1893) zu Gottlob Freges Hauptwerk, den "Grundgesetzen der Arithmetik", in dem er seine fulminante Psychologismus-Kritik vorträgt; die drei von Frege selbst veröffentlichten "Logischen Untersuchungen" (1918-1923), in denen er "die Ernte [s]eines Lebens heimbringen" wollte; und schließlich ein Fragment aus seinem Nachlass, das der Entwurf zu einer vierten LU ist.

Der Optimismus vieler Vertreter der „Analytischen Philosophie“, in Theorien der Bedeutung die Grundlage für die Lösung aller philosophischen Fragen zu erhalten, kontrastiert mit der beständigen Suche nach einer Basis, von der aus eine Theorie der Bedeutung überhaupt erst formuliert werden könnte. Auch über das Werk Gottlob Freges wird das doppelte Urteil gepflegt, zwar durch die Kritik der erkenntnistheoretischen Ansätze des 19. Jahrhunderts und mit der Analyse des Gehalts sprachlicher Ausdrücke richtungsweisende Arbeit geleistet zu haben. Zugleich aber wird behauptet, Frege sei (...) in seinem Anti-Psychologismus „zu weit“ gegangen und seine sprachphilosophischen Kategorien seien „problematisch“ oder „nicht hinreichend geklärt“. Freges Interesse an Funktionen, die den Kategorien „Sinn“ und „Bedeutung“ zugeteilt sind, macht deutlich, dass seine Ausführungen in einem viel engeren Verhältnis zu seiner Philosophie der Mathematik stehen, als gemeinhin angenommen wird. Dies könnte verständlich machen, warum mit Sinn und Bedeutung manche Fragen zur Funktionsweise von Ausdrücken nicht nur nicht beantwortet sind, sondern der Antwortversuch in Aporien führt. (shrink)

In this paper I focus my attention on the proposal given by Howard Wettstein in 1980 to the cognitive phenomenon stated by Gottlob Frege in his paper “On sense and reference”. I offer three arguments in order to show that his answer does not weaken this phenomenon. Particularly, I defend three ideas: first, it is legitimate that philosophical semantics, in contrast with what Wettstein defends, provides an answer to the cognitive phenomenon; second, Wettstein does not conceive Frege’s argument correctly by (...) considering it generates a semantic theory from a purely mentalist phenomenon; third, the explanation supplied by Wettstein is assumed by Frege when he states the phenomenon. (shrink)

By any reasonable reckoning, Gottlob Frege's ‘On Sense and Reference’ is one of the more important philosophical papers of all time. Although Frege briefly discusses the sense-reference distinction in an earlier work, it is through ‘Sense and Reference’ that most philosophers have become familiar with it. And the distinction so thoroughly permeates contemporary philosophy of language and mind that it is almost impossible to imagine these subjects without it.The distinction between the sense and the referent of a name is introduced (...) in the second paragraph of ‘Sense and Reference.’.

This paper concerns the dialectal role of Frege Cases in the debate between Concept Cartesians and Concept Pragmatists. I take as a starting point Christopher Peacocke’s argument that, unlike Cartesianism, his ‘Fregean’ Pragmatism can account for facts about the rationality and epistemic status of certain judgments. I argue that since this argument presupposes that the rationality of thoughts turn on their content, it is thus question-begging against Cartesians, who claim that issues about rationality turn on the form, not the content, (...) of thoughts. I then consider Jerry Fodor’s argument that ‘modes of presentation’ are not identical with Fregean senses, and argue that explanatory considerations should leads us to reject his ‘syntactic’ treatment of Frege cases. Rejecting the Cartesian treatment of Frege cases, however, is not tantamount to accepting Peacocke’s claim that reasons and rationality are central to the individuation of concepts. For I argue that we can steer a middle course between Fodor’s Cartesianism and Peacocke’s Pragmatism, and adopt a form of Pragmatism that is constrained by Fregean considerations, but at the same time denies that concepts are constitutively tied to reasons and rationality.

Gottlob Frege has exerted an enormous influence on the evolution of twentieth-century philosophy, yet the real significance of that influence is still very much a matter of debate. This book provides a completely new and systematic account of Frege's philosophy by focusing on its cornerstone: the theory of sense and reference. Two features distinguish this study from other books on Frege. First, sense and reference are placed absolutely at the core of Frege's work; the author shows that no adequate account (...) of the theory can avoid analysing the notion of thought that underpins it, or explaining how it has clarified our concept of judgement. Second, the theory is situated within the development of Frege's thought; the author reveals how the theory caused Frege to alter many of his fundamental views. In doing so the author presents a clearer picture of the problems the theory was intended to solve, and delineates more sharply the characteristic features of Frege's philosophy. (shrink)

This book aims to develop certain aspects of Gottlob Frege’s theory of meaning, especially those relevant to intensional logic. It offers a new interpretation of the nature of senses, and attempts to devise a logical calculus for the theory of sense and reference that captures as closely as possible the views of the historical Frege. (The approach is contrasted with the less historically-minded Logic of Sense and Denotation of Alonzo Church.) Comparisons of Frege’s theory with those of Russell and others (...) are given. It is in the end shown that developing Frege’s theory in these ways reveals serious problems hitherto largely unnoticed, including those possibly rendering a Fregean intensional logic inconsistent even if his naïve class theory is excluded.

In this dissertation I present an interpretation of Gottlob Frege's "On Sense and Reference", and Bertrand Russell's "On Denoting." I consider other works by both authors, but those two essays structure the dissertation as a whole. Both essays, I argue, are works in ontology. What I mean by 'ontology' is best explained by the problems I claim motivate Frege and Russell. ;Frege posits the existence of a class of entities he calls "senses" to serve as constituents of the truth-makers for (...) sentences containing propositional attitude verbs . I read Russell's work as a response to Frege's. Russell contends that senses are objectionable on their own terms, and that they are unnecessary because the problem that seems to require them, can be solved without them. Russell offers his theory of descriptions as an alternative to Frege's distinction between sense and reference. In place of senses, Russell's ontology contains universals, both monadic properties and relations. Ultimately, I argue that Russell's response to Frege is a failure. The theory presented in "On Denoting" cannot solve the problem of false belief. That is, it cannot account for the truth of sentences such as 'John believes P', where the 'P' is replaced by a false sentence. (shrink)

The conclusion of the investigation is that the NTR has indeed succeeded in presenting a new and compelling picture of how referring terms function, but that the case for these new developments constituting a decisive critique of Frege is not completely made out. In general, Fregean theory seems more flexible and susceptible to reconstruction than the NTR would make it out to be. Though certain assumptions of Frege may prove irretrievable, there are core principles that the NTR has not succeeded (...) in disproving. ;Recent work on proper names, natural kind terms and indexicals has challenged the classical semantic theory of Frege. The so-called New Theory of Reference denies Frege's doctrine that every singular term has a sense and a reference . The question is: is this critique successful? This divides into the following problems: Does the NTR present a compelling account of the nature of reference? Even if the answer to is affirmative, does this imply that Frege's theory was mistaken, or can his theory be amended to incorporate the new developments in semantics? ;In attempting to answer these questions, an analysis is provided of important tenets of the NTR, such as the insistence on a "division of linguistic labor", on the "social" nature of our use of certain referring terms, and on the frequent ignorance of speakers concerning the objects they purport to refer to. The NTR tends to make precise Frege's ideas to criticize them, while not making its own doctrines sufficiently precise to permit similar scrutiny. In the process of explicating these new doctrines of the NTR, it is found that they too are subject to serious problems. The focus is on Donnellan's work on proper names, Putnam's on natural kind terms, and Perry's on indexicals. Where these authors' theses are found to be cogent an attempt is made to reconstruct Fregean theory to account for them. (shrink)

Freges Unterscheidung zwischen Sinn und Bedeutung von Ausdrücken ist oft als ein Modell für die Semantik natürlicher Sprachen betrachtet worden. Dagegen zeigt die vorliegende Untersuchung (z.T. durch Einordnung Freges in den historischen Kontext), dass Sinn und Bedeutung bei Frege termini technici darstellen, die der Konstruktion seiner formalen Sprache, der Begriffsschrift, dienen. Diese soll den logischen Defekten der natürlichen Sprache abhelfen, indem sie deren Vagheit und Mehrdeutigkeit eliminiert. Freges Sinn und Bedeutung sind daher von der sprachlichen Bedeutung natursprachlicher Ausdrücke scharf zu (...) unterscheiden. (shrink)

The article aims at exposition, commenting and interpreting Frege’s theory of meaning, based on the requirement to distinguish, in the meaning of a sign, the level of sense (Sinn) and the correlative level of reference (Bedeutung). The author directs attention to some logico-linguistic reasons which seem to have urged Frege to advocate the differential conception of meaning. In accordance with Frege’s decision to use the theoretical notions of sense and reference, the relevant semantic features of a proper name as well (...) as of a declarative sentence are explored. Since only something which constitutes what someone who understands the word or expression implicitly grasps can be counted as a possible ingredient in meaning, the claim is made that entities on the level of reference (objects, truth-values) are not undeniable ingredients of meaning. Sense therefore is left in the role of a genuine semantic concept. Keywords: Frege, language, meaning, sense, reference. (shrink)

So-called 'Frege cases' pose a challenge for anyone who would hope to treat the contents of beliefs (and similar mental states) as Russellian propositions: It is then impossible to explain people's behavior in Frege cases without invoking non-intentional features of their mental states, and doing that seems to undermine the intentionality of psychological explanation. In the present paper, I develop this sort of objection in what seems to me to be its strongest form, but then offer a response to it. (...) I grant that psychological explanation must invoke non-intentional features of mental states, but it is of crucial importance which such features must be referenced. -/- It emerges from a careful reading of Frege's own view that we need only invoke what I call 'formal' relations between mental states. I then claim that referencing such 'formal' relations within psychological explanation does not undermine its intentionality in the way that invoking, say, neurological features would. The central worry about this view is that either (a) 'formal' relations bring narrow content in through back door or (b) 'formal' relations end up doing all the explanatory work. Various forms of each worry are discussed. The crucial point, ultimately, is that the present strategy for responding to Frege cases is not available either to the 'psycho-Fregean', who would identify the content of a belief with its truth-value, nor even to someone who would identify the content of a belief with a set of possible worlds. It requires the sort of rich semantic structure that is distinctive of Russellian propositions. There is therefore no reason to suppose that the invocation of 'formal' relations threatens to deprive content of any work to do. (shrink)

Argues that because Frege's semantic ideas were introduced into analytic philosophy of language by Russell and Carnap the general understanding of his distinction between sense and reference has been severely misrepresented.

Russell's On Denoting and Frege's On Sense and Reference are now widely held to be two of the founding papers of twentieth century philosophy and form the heart of the famous "linguistic turn". The Metaphysicians of Meaning is the first book to challenge the accepted secondary work on these two seminal papers, forcing us to reconsider the interpretation of these two vitally important works on meaning.

One of the most important objections to information-based semantic theories is that they are incapable of explaining Frege cases. The worry is that if a concept’s intentional content is a function of its informational content, as such theories propose, then it would appear that coreferring expressions have to be synonymous, and if this is true, it’s difficult to see how an agent could believe that a is F without believing that b is F whenever a and b are identical. I (...) argue that this appearance is deceptive. If we heed the distinction between the analog and digital contents of a signal, it is actually possible to reconstruct something akin to Frege’s sense/reference distinction in purely information-theoretic terms. This allows informational semanticists to treat coreferring expressions as semantically distinct and to solve Frege cases in the same way that Frege did—namely, by appealing to the different contents of coreferring expressions. (shrink)

This paper is a critical investigation of Gottlob Frege's and Bertrand Russell's views on the sense or meaning of singular terms. In his famous "On denoting" Russell erects his case on objections that he raises against Frege. I suggest that Russell's criticisms of Frege are seriously misguided, due in large measure to the uneven applications of his terminology when addressing Frege's views.

This book is in the Studies in Philosophy: Outstanding Dissertations series. Its central theme is that Frege’s concept-notation is inadequate because it does not formalize his semantic theory after the introduction of the sense-reference distinction in 1891. This failing, according to Klement, opens Frege up to a number of philosophical and logical challenges that can be met only by completing the project of showing “how Frege’s mature semantic views would be incorporated into his mature logical system”, a project which, Klement (...) plausibly argues, Frege would have endorsed. This involves: allowing the concept-notation to represent explicitly what is expressed in natural language with indirect constructions such as “said that...” or “believes that... ”; allowing principles to be formulated over this notion which capture inferences involving indirect constructions such as: The Morning Star is a planet, Gottlob believes the Morning Star is a planet, so, Gottlob believes something true; being able to respond to certain objections to Frege’s views, some first bruited by Russell and in later correspondence, others involving the identity conditions on intensional entities and “quantifying in” ; making the concept-notation reflect Frege’s ontology; and evaluating the consistency of Frege’s ontology. The chapters of this book are devoted to fulfilling this project “based upon a careful reading of Frege’s own works”, and their contents are mostly self-explanatory. Chapter 2 sets out the formal apparatus of the Grundgeseze, even the bits Frege left out. Chapter 3 is the most philosophical. Senses are construed as interpersonally accessible information uniquely true of the references they determine—senses are objects and functions in the “third realm.” Singular terms are associated with an impossibly rich hierarchy of senses as objects. Functors, including predicates, are associated with senses as functions. Sentences are associated with thoughts as objects, composed of constituent sense-functions, and in many cases, also sense-objects. Robust compositionality at the level of sense raises the question of the nature of the relation between constituents and the whole—is it functional, or not? Compositionality potentially conflicts with a number of other claims, and Klement’s conclusion is reasonable: “the context principle, the priority thesis, and the possibility of there existing multiple decompositions for the same Gedanke, do not pose any great difficulty for the compositionality principle or the understanding of Gedanke as having determinate inner structures”. Chapter 4 sets out Church’s original system and investigates reformulations suggested by Church himself, Kaplan, and others. Chapter 5 presents Klement’s formalization of an intensional logic of sense and reference, based on the results of chapters 2 and 4, and sufficient for indirect speech and quantifying-in, but containing a contradiction. Chapter 6 takes up arguments of early Russell, Searle, and Bergmann. Chapter 7 addresses strategies for repairing the inconsistencies of chapter 5, but in a Fregean spirit: dropping some realms of entities, restricting their number, or modifying our conception of their nature.

The author compares Frege's theory of sense and reference with Wittgenstein's Tractatus theory of "logical picturing through language." The aim of Frege's theory, according to Carl, is to arrive at a concept of judgment suitable for his logic and at a satisfactory account of the relation between thought and truth. In all this, Frege uses both linguistic and epistemological reflections. Wittgenstein's interest is different: his theory is concerned with the relation between language and reality, his concept of truth is one (...) of correspondence. The words "Sinn" and "Bedeutung" stand, in Tractatus, for the objective "correlates" of sentence and name respectively. The Sinn of a sentence is a function of the Bedeutung of the names occurring in it. Sentences have Sinn, words have Bedeutung. According to Carl, Frege and Wittgenstein ask different questions and pursue different explanatory goals. Frege's problem, unlike Wittgenstein's, is oriented by a Kantian understanding of the nature of scientific knowledge. That for Frege the Sinn is the fact that is represented in a sentence, points on the one hand to Frege's basically epistemological interest and, on the other, to Wittgenstein's linguistic-ontological concern. Tractatus gives a version of correspondence theory, which Frege explicitly rejects; just as Frege's concern with assertion and judgment are rejected by Wittgenstein as being of no logical importance. In spite of these fundamental differences in orientation, they do have, according to Carl, common theories and thematic interconnections. Both connect the idea of Sinn with understanding of linguistic expressions, both have a functional interpretation of the sense or the reference of complex expressions. Both accord centrality to the concept of truth. (shrink)

Russell said that the measure of a theory is its ability to solve puzzles. i show that frege's theory of sense and denotation is the equal of russell's theory of definite descriptions for solving the latter's three puzzles of denoting. i then show that their theories have some important features in common, which are key to solving two of the puzzles. the most important of these features is that each theory denies that the meaning of a description is its denotation.

According to Russell’s famous Gray’s Elegy argument within “On Denoting”, Frege’s distinction between Sinn and Bedeutung is problematic when applied to a denoting phrase like ‘the first line of Gray’s Elegy’, which denotes a linguistic expression: ‘The curfew tolls the knell of parting day’. The author shows that Russell’s Gray’s Elegy argument involves imprecision in the use of quotation marks as well as the unwarranted identification of an expression’s meaning with the expression itself.

Important aspects of its philosophical basis, and its significance for the foundations of mathematics, appeared in The Foundations of Mathematics (FA, 1884). Six years later, at the beginning of the 1890s, Frege published three articles that mark significant changes in his conception: "Function and Concept" (FC, 1891), "On Sense and Reference" (SR, 1892) and "Concept and Object" (1892). Notable among these changes are: (a) The systematic distinction between the sense and the reference of expressions as two separate ingredients of their (...) meaning. (b) The extension and generalization of the notion of function to include the conception of concepts and relations as functions to truth-values, and the corresponding conception of the two truth-values as objects. These changes were immediately incorporated in the mature, authoritative exposition of his logic in his magnum opus: Basic Laws of Arithmetic (BL), whose first volume appeared in 1893. (shrink)

This paper continues Michael Dummett's and my discussion of Frege in The Philosophy of Michael Dummett [2007]. Most of it is about Dummett’s change in view on Frege’s senses and objects. The issues include: the cognitive order versus the ontological order for the forward road; the nature and identity of senses and the different senses of "intension;" the nature of saturation; whether special quantifiers are now needed for senses; and Frege’s earlier and later permutation arguments. I discuss the implications of (...) the forward road for intuitionism as well. (shrink)

Gottlob Frege's brief article Uber Sinn und Bedeutung (On Sense and Reference) has come to be seen, in the century since its publication in 1892, as one of the seminal texts of analytic philosophy. It, along with the rest of Frege's writings on logic and mathematics, came to mark out a whole new domain of inquiry and to set the agenda for it. This volume bears witness to the continuing importance and influence of that agenda. It contains original papers written (...) by leading Frege scholars for the conference held in 1992 in Karlovy Vary to celebrate the centenary of the publication of Frege's essay. The 14 essays show how the questions Frege discusses in that essay connect intimately with issues much debated in current philosophy of language and philosophy of mind. (shrink)

The article presents Frege's distinction between Sense and Reference. After a short introduction, it explains the puzzle which gave rise to the distinction; Frege's earlier solution, and his reasons for its later repudiation. The distinction, which embodies Frege's second solution, is then discussed in two phases. The first, which is restricted to proper names, sets out its most basic features. The second discusses 'empty' names; indirect speech, and the distinction for predicates and for complete sentences. Finally, two criticisms, by Russell (...) and by Kripke, are briefly set out.

The first page of Frege’s classic “Uber Sinn und Bedeutung” sets for more than a hundred years now the agenda for much of semantics and the philosophy of mind. It presents a purported puzzle whose solution is said to call upon the “entities” of semantics (meanings) and psychological explanation (Psychological states, beliefs, concepts). The paper separates three separate alleged puzzles that can be read into Frege’s data. It then argues that none are genuine puzzles. In turn, much of the Frege-driven (...) theoretical development, motivated as an inevitable “solution”, is thrown into doubt. (shrink)
