NeoRussellian Logicism

Bruno Jacinto (CFCUL) & José Mestre (University of Stirling & LanCog)

Frege’s and Russell’s original projects of deriving the basic laws of arithmetic in pure logic were based on contrasting conceptions of the natural numbers. While Frege thought numbers were logical objects, Russell took them to be attributes of attributes of objects. Both projects failed. The Fregean conception of numbers has been at the basis of attempts to revive the logicist programme. Alas, neoFregean logicism has been the target of devastating objections. All the while, the Russellian route for establishing arithmetic’s logicality has been neglected. Yet, Russell’s is the more promising view on natural numbers. In this talk we show that our NeoRussellian Logicism is capable of finally sustaining the view that arithmetic is nothing but logic. We furthermore indicate one of its striking consequences: that arithmetic is an inherently modal discipline.
