Abstract

This paper deals with three main issues of Wittgenstein’s philosophy of language: the theory of logical forms, the theory of objects in the Tractatus and his criticisms of the sense-data theory. Wittgenstein’s theses are here compared with those of Leo-nardo Polo’s philosophy, and especially, with some Polo’s remarks on the making of a transcendental language, nominalism and the concept of knowledge in Wittgen-stein’s thought.
