Abstract

During his long scholarly life, Brian McGuinness did substantial research into the intellectual relationships which Ludwig Wittgenstein established with Piero Sraffa and Raffaello Piccoli respectively during his first years back in Cambridge. The essay runs through McGuinness’s works on both topics, then it illustrates a few outcomes of the research we performed together in the last years of his life. Finally, the paper sketches out some lines of investigation about both Wittgenstein’s biography and his movement of thought which our research further suggests.
