Sraffa, Wittgenstein, and Gramsci
探讨斯拉法对维特根斯坦哲学的关键影响，以及斯拉法的哲学观点如何塑造其经济学贡献，帮助理解他如何改变经济学提问的方式。
Two distinct but interrelated issues are investigated here. The first concerns Sraffa's critical role in contemporary philosophy through his pivotal influence on Wittgenstein. The intellectual origins of this profound influence can be traced to the philosophical interests of the activist political circle in Italy (clustered around the journal L'Ordine Nuovo) to which both Sraffa and Antonio Gramsci belonged. The second inquiry concerns the influence of Sraffa's philosophical views on his economics. Sraffa's economic contributions can be much better understood by paying attention to the way Sraffa changed the nature of the questions asked, rather than seeking different answers to already established questions.
