Decomposition and analysis in frege’sgrundgesetze
Gregory Landini · History and Philosophy of Logic · 1996
Frege seems to hold two incompatible theses:(i) that sentences differing in structure can yet express the same sense; and (ii) that the senses of the meaningful parts of a complex term are determinate parts of the sense of the term. Dummett offered a solution, distinguishing analysis from decomposition. The present paper offers an embellishment of Dummett’s distinction by providing a way of depicting the internal structures of complex senses—determinate structures that yield distinct decompositions. Decomposition is then shown to be adequate as a foundation for the informativity and analyticity of logic
