 Logical restriction on what counts as reasoning culminates, on Nye’s reading, when Gottlob Frege moves logic out of human discourse to formulate it in a symbolic language. Frege’s functionalist notation promises to express all forms of truth with the aim, Nye suggests, “that thought will be unified and logical errors in science, mathematics, and philosophy exposed” (1990: 131). Using Frege’s approach, how a concept refers to the world becomes “an objective fact:…one cannot invent its value” (1990: 135). As a result, the institutions that render concepts meaningful, including the social institution of language, stand beyond question, creating a new form of muteness that harkens back to Parmenides. The surrounding silence breaks again when the Vienna Circle adds empirical input in place of the concepts on which the Fregean functions work. Nye indicates that this theoretical development places science above meaningful criticism, and so allows scientific reasoning to be co-opted by authoritarian regimes (1990: 163–171).
