Frege on Sense and Reference


frege on Sense and Reference

of applying the binary function ( ) to the numbers 7 and 1 as arguments, in that order. It is one which evolves out of the ideas that (1) certain concepts and laws remain invariant under permutations of the domain of quantification, and (2) that logic ought not to dictate the size of the domain of quantification. Using this insight, Frege took true statements like There are eight planets and There are two authors of Principia Mathematica to be second level claims my Child is Innocent! about the concepts planet and author of Principia Mathematica, respectively. This early theory of meaning explains how the significance or reference of a sentence (its truth value) depends on the significance or reference of its parts.

The sixth sense1,

Where expressions that have the same reference are substituted in sentences, truth value remains the same (even if other stuff changes) Try it out on the Morning Star/Evening Star example! Polish noble family who left Poland in the 17th the Many Uses of Apple Cider Vinegar - Informative century. Frege's goal was to show that mathematics grows out of logic, and in so doing, he devised techniques that took him far beyond the Aristotelian syllogistic and Stoic propositional logic that had come down to him in the logical tradition. Hell go on to use that distinction in developing a theory that saves compositionality from putative counterexampleslike the Morning Star/Evening Star problem. More generally, if given a series of facts of the form aRb, bRc, cRd, and so on, Frege showed how to define the relation x is an ancestor of y in the R-series (Frege referred to this as: y follows x in the R -series).

Only becomes legitimate once one supplies the concept being counted, such as army, division, regiment, or company (1884, 46). Frege never fully recovered from the fatal flaw discovered in the foundations of his Grundgesetze. If identity is a relation between objects then (1) should be as trivial as (2) and wouldnt be an important astronomical discovery. So the Principle of Identity Substitution appears to break down in the context of propositional attitude reports. The crucial case of the law may be formulated in modern notation as follows.
