Résumé/Abstract

« The study of grammar, in my opinion, is capable of throwing far more light on philosophical questions than is commonly supposed by philosophers. Although a grammatical distinction cannot be uncritically assumed to correspond to a genuine philosophical difference, yet the one is primâ facie evidence of the other, and may often be most usefully employed as a source of discovery.”
Bertrand Russell The Principles of Mathematics, Cambridge, 1903, p. 42.
