A note on arithmetic and logic in the ``Tractatus''

Abstract

The extra propositions which Wittgenstein added to Ramsey's copy ofthe 'Tractatus' during their discussions in 1923 provide evidence,Wrigley argues, that Wittgenstein's view of mathematics was quitedifferent from logicism. Contrary to this, Frascolla tries to provethat the label 'no-classes logicism' tallies with the 'Tractarian'view of arithmetic.
