One of the pleasures of reading Amartya Sen’s new memoir, Home in the World, is stumbling upon little anecdotes that provide new perspectives on, or an opportunity for a deepening engagement with, major intellectual figures.
One such occasion for me was Sen’s discussion of the influence of the economist Piero Sraffa, one of Sen’s academic mentors at Cambridge in the 1950s, on the later thought of the philosopher Ludwig Wittgenstein.
That Sraffa was influential on Wittgenstein is undeniable. In his preface to the Philosophical Investigations, Wittgenstein describes the path that led him to repudiate his earlier philosophical positions, as elucidated in his first book, the Tractatus Logico-Philosophicus, and to arrive at the positions that he develops in the Philosophical Investigations. Wittgenstein notes that, “since beginning to occupy myself with philosophy again, sixteen years ago, I have been forced to recognize grave mistakes in what I wrote in that first book. I was helped to realize these mistakes—to a degree which I myself am hardly able to estimate—by the criticism which my ideas encountered from Frank Ramsey … . Even more than to this … criticism I am indebted to that which a teacher of this university, Mr. P. Sraffa, for many years unceasingly practised on my thoughts. I am indebted to this stimulus for the most consequential ideas of this book.” (Philosophical Investigations, viii)
Though Wittgenstein doesn’t elaborate on the nature of Sraffa’s contributions, Sen locates Sraffa’s influence on Wittgenstein in Sraffa’s insistence that Wittgenstein’s earlier reductionist theory of meaning (more specifically, the picture theory of meaning of the Tractatus) was inadequate to capture the complexities of human language use. Sraffa emphasized the complex social arrangements that sustained and gave meaning to language, social arrangements that Wittgenstein attempted to capture with his notion of “language games” in the Philosophical Investigations.
