According to the theory in question, propositions or Thoughts. (Gedanken) exist in the quite special sense of being ‘wirklich’—a. Fregean term of art which I shall. In focusing on Frege’s account of thinking, rather than ‘thoughts [Gedanken]’ or the ‘truth-values [Wahrheitswerthe]’ of thoughts, their approach. PDF | Michael Dummett has advanced, very influentially, the view that Frege means truth conditions by his notion of thought (Gedanke). My aim in this paper is to.

His theory of meaning, especially his distinction between the sense and reference of linguistic expressions, was groundbreaking in semantics and the philosophy of language. It has been translated by E.

Gottlob Frege (1848—1925)

He had a profound and direct influence on such thinkers as Russell, Carnap and Wittgenstein. And as “On Sense and Reference. Feigl in Feigl and Sellars [] pp. According gedanie Frege, if we look at the contexts in which number words usually occur in a proposition, they appear as part of a sentence about a concept, specifically, as part of an expression that tells us how many times a certain concept is instantiated. Having exhibited this possibility, Frege’s larger purpose was to defend the view that arithmetic is a branch of logic, a view known as logicism: What is perhaps most problematic, however, is Garavaso and Vassallo’s third category of purely ‘psychological’ thinking.

Frege was born on November 8, trege the coastal city of Wismar in Northern Germany. De Gruyterpp. Though the German book never appeared, the papers were published together in Logische Untersuchungened. Referenceor, “Bedeutung” fregge to proper nameswhere a given expression say the expression “Tom” simply refers to the entity bearing the name the person named Tom. This maturation of Frege’s semantic and philosophical views lead to gexanke in his logical language, forcing him to abandon an almost completed draft of his work in logic and the foundations of mathematics.

White in Hermes et al.


Fedanke Grundlagen der Arithmetik: 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.


Translated as “Function and Concept. Sluga’s source was an article by Eckart Menzler-Trott: Review of Philosophie der Arithmetikby Edmund Husserl. Moreover, Frege’s logical system was second-order.

I’m indebted to Wolfgang Kienzler for suggesting several important improvements to this catalog. Their main thesis is that, for Frege, there are three distinct ‘types’ of thinking However, his work was interrupted by changes to his views.

You could not be signed in. It is an active matter of debate and discussion to what extent and how this principle coheres with Frege’s later gwdanke of meaning, but what is clear is that it plays an important role in his own philosophy of mathematics as described in the Grundlagen.

Exposition of the System. It should be kept in mind that Frege was employed as a mathematician, not a philosopher, and he published his philosophical papers in scholarly journals that often were hard to access outside of the German-speaking world. Garavaso and Vassallo conclude that pure thinking cannot be ’embodied’ in ‘the mind of an individual subject’, since the human mind always does ‘include’ a psychological element The case is special because what is here being called the extension of a predicate, or a set, is only one type of “value-range” of a function.

His main argument against this view, however, was simply his own work in which he showed that truths about the nature of succession and sequence can be proven purely from the axioms of logic. Translated as Posthumous Writings. He did not live to see the profound impact he would have on the emergence of analytic philosophy, nor to see his brand of logic–due to the championship of Russell–virtually wholly supersede earlier forms of logic.

In the four semesters of his studies he attended approximately twenty courses of lectures, most of them on mathematics and physics.

The Foundations of Frege’s Logic. Dummett’s Frege writings also left considerable imprints on then-emerging work exploring broadly Fregean accounts of sense and reference Tyler Burge, Gareth Evans, John McDowell.

Frege thinks Thoughts cannot be Ideas, for Ideas have specific properties that Thoughts do not: Harvard University Press, The second argument is pragmatic: In SpringFrege began studies at the University of Jena. However, x falls in the ancestral of this relation with respect to y just in case x is the child of yor is the child of y ‘s child, or is the child of y ‘s child’s child, etc. As articulated in the Grundlagen and refined in the Grundgesetze and elsewhere, Frege’s logicism seems to involve: There is a reply in defense of Hilbert by A.


Because the sense of a whole proposition is determined by the senses of the parts, and 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. In his own logical systems, Frege introduced signs standing for the negation and conditional functions.

Frege found this unacceptable for a language which was to be used to demonstrate mathematical truths, because the signs would be ambiguous.

This idea was formulated in non-symbolic terms in his The Foundations of Arithmetic Thus, Thoughts are the bearers of truth, but do not exist as external objects nor as Ideas.

We have seen that Frege was a harsh critic of psychologism in logic. Clearly, however, these expressions do not present that concept in the same way. His position was unsalaried during his first five years, and he was supported by his mother.

A frequently noted example is that Aristotle’s logic is unable to represent mathematical statements like Euclid’s theorema fundamental statement of number theory that there are an infinite number of prime numbers.

As already mentioned, Frege does not think Thoughts are external, sensible objects: The system of the Grundgesetze entails that the set thus characterised both is and is not a member of itself, and is thus inconsistent.
