Gottlob Frege

By contrast, the sense or “Sinn” associated with a complete sentence is the thought it expresses. Felix Meiner HermesH.

His full christened name was Friedrich Ludwig Gottlob Frege. Furth in Furth [] pp. Blackwell, third edition GeachP. Olms, ; reprinted in Thiel []. Frege argues that Thoughts may be expressed without thereby being asserted: First published in Semantics of Natural Languages. Mathematisch-physische Klasse48 In response, they chart out several dimensions of Frege’s anti-psychologism about logic to make room for Frege’s willingness nevertheless to discuss ‘our apprehension of logic’ and the acts of ‘abstraction’ needed to bring its subject-matter to ‘consciousness’ 32f.

Contributions to the Philosophy of Mathematics Frege was an ardent gevanke of logicism, the view that the truths of yedanke are logical truths.

Just as the sense of feege name of an object determines how that object is presented, the sense of a proposition determines a method of determination for a truth-value. Olms, ; reprinted in Thiel []with Corrigenda six pages and some textual criticism. Added to PP index Total downloads 25of 2, Recent downloads 6 months 13 37, of 2, How can I increase my downloads? According to Frege, the references of these incomplete expressions are not objects but functions.

Where would he agree and where would he disagree? White in Hermes et al. Frege had friendly relations with Jews in real life: Det final properties Hedanke discusses are the under- and over-determination of Thoughts by sentential content.

This further restriction seems necessary since Frege accepts that all sciences e.

Friedrich Frommann, ; reprinted in Angelelli [] pp. Typically, such cases involve what Frege calls “indirect speech” or ” oratio obliqua “, as in the case of statements of beliefs, thoughts, desires and other so-called “propositional attitudes”, ser as the examples of 5 and 6. As certain commentators have noted, it is not even necessary that the sense of the name be expressible by some descriptive phrasebecause the descriptive information or properties in virtue of which the reference is determined may not be directly nameable in any natural language.


He put this to use in the Grundgesetze to dr the natural numbers. Bertrand Russell, just when the printing of this volume was nearing its completion.

Frege’s suggestion is that “the number of F s” means the same as “the value-range of gedanek concept being a value-range of a concept instantiated equally many times as F. Harvard University Press, pp. However, expressions also have their secondary references for reasons which should already be apparent in contexts such as “it is informative that Although there had been attempts to fashion at least the core of such a language made by Boole and others working in the Leibnizian tradition, Frege found their work unsuitable for a number of reasons.

It analyzed propositions in terms of subject and predicate concepts, which Frege found to be imprecise and antiquated. In his mind, they are objects every bit as real as tables and chairs.

Because the sense of a whole proposition is determined by the senses of the parts, fedanke the reference of a whole proposition is determined by the parts, Frege claims that propositions in which such expressions appear are able to express thoughts, but are neither true nor false, because no references are determined for them.

To think otherwise is to confuse something’s being true with something’s being-taken-to-be-true. The values of fdege concepts could then be used as arguments to other functions. Wissenschaftliche Buchgesellschaft and Hildesheim: Rather than understanding one as the concept a concept has just in case it is instantiated by a unique object, it is understood as the value-range consisting of value-ranges of concepts instantiated by unique objects.


Frege was also a critic of Mill’s view that arithmetical truths are empirical truths, based on observation. Frege rejects this view for a number of reasons. A logic-mathematical enquiry into the concept of numberOxford: Frege suggests that rival views are often the result of attempting to understand the meaning of number terms in the wrong way, for example, in attempting to understand their meaning independently of the contexts in which they appear in sentences.

As they understand it, psychological thinking is composed entirely of items which ‘ cannot be aimed at thoughts’ 57; my ital. Frege pointed out that it is not just observable things that can be counted, freg that mathematical truths seem to apply also to these things. Oxford University Press StachelrothJ.

Instead, they posited some weaker form of “equality” such that the numbers 4 x 2 and 11 – 3 would be said to be equal in number or equal in magnitude without thereby constituting one and the same thing. It has since been proven impossible to devise a system for higher-order logic with a finite number of axioms that is both complete and consistent.

He has already defined one and zero; they are each unique, but different from each other. Frege Against the Formalists II: It was divided into a “primary logic” and “secondary logic”, bifurcating its propositional and categorical elements, and could not deal adequately with multiple generalities. Frege had aimed to use the logical language of the Begriffsschrift to carry out his logicist program of attempting to show that all of the basic truths of arithmetic could feege derived from purely logical axioms.
