(Jul., 1956), pp. 289-311 (‘Der Gedanke’ is the untranslated name of the same work) Summary Frege explores the cognitive phenomenon of taking something to be true. His central claim is that to take something as true is to enter into a relation with an abstract entity called a ‘Thought,’ which to Frege is a specific sort of meaning, expressible through sentences, which may be either true or false.* In the midst of formulating this answer, Frege clarifies what he means by ‘true’, explains what he thinks are some basic properties of Thoughts, and engages in a discussion of the precise ontological status of Thoughts.

Frege begins by clarifying what he means by ‘truth,’ since without a more clear notion of this term his thesis about what it is to take something as true does not have meaning. Frege eschews several commonsense uses of the word before stating that the sort of truth he wishes to discuss is that which is sought out by the sciences (326). In an attempt to explicate the notion further, Frege gives a tentative catalog of things truth – which for the sake of discussion he assumes is a property – may be predicated of: pictures, ideas, sentences, and Thoughts. Frege rejects the claim that truth may genuinely be predicated of pictures and ideas, for he thinks such predication requires a correspondence theory of truth, or, a theory which states that truth consists in some correspondence between a picture or idea and item in the external world.

Over the course of his life, Gottlob Frege formulated two logical systems in his attempts to define basic concepts of mathematics and to derive mathematical laws from the laws of logic. In his book of 1879, Begriffsschrift: eine der arithmetischen nachgebildete Formelsprache des reinen Denkens, he developed a second-order predicate calculus and used it both to define interesting mathematical concepts and to state and prove mathematically interesting propositions. However, in his two-volume work of 1893/1903, Grundgesetze der Arithmetik, Frege added (as an axiom) what he thought was a logical proposition (Basic Law V) and tried to derive the fundamental axioms and theorems of number theory from the resulting system. Unfortunately, not only did Basic Law V fail to be a logical proposition, but the resulting system proved to be inconsistent, for it was subject to Russell’s Paradox. Until recently, the inconsistency in Frege’s Grundgesetze overshadowed a deep theoretical accomplishment that can be extracted from his work. The Grundgesetze contains all the essential steps of a valid proof (in second-order logic) of the fundamental propositions of arithmetic from a single consistent principle.
