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, fregf no references are determined gefanke them. 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.

Frege’s published philosophical writings were of a very technical nature and divorced from practical issues, so much so that Frege scholar Dummett expresses his “shock to discover, while free Frege’s diary, that his hero was an anti-Semite. Fedanke Frege, these expressions would have different senses but the same reference. Frege was also an opponent of formalism, the view that arithmetic can be understood as the study of uninterpreted formal systems.

The Philosophy of Frege. He began gwdanke a limited number of fixed axioms, introduced explicit inference rules, and aimed to derive all other logical truths including, for him, the truths of arithmetic from them.


In addition to quantifiers ranging over objects, it also contained quantifiers ranging over first-level functions.

Take care that nothing gets lost. However, these were not wholly new works, but later drafts of works he had initiated in the s. He also reiterated the arguments of others: Filed under Article Summaries. In “Funktion und Begriff”, the distinction between the sense and reference of signs in language is first made in regard to mathematical equations.

Olms, ; reprinted in Thiel []with Corrigenda six pages and some textual criticism. It is precisely in its expansion of the epistemic power of thinking along these lines that Frege’s Erkenntnistheorie becomes the most controversial, when viewed from the perspective of post-Kantianism.
