The present paper discusses the characteristics of performative speech through three distinct but related episodes: 1. the ancient origins of “convincing speech“ in Homeric and Sophistic discourse; 2. the treatment of linguistic issues through speech by South Africa’s Truth and Reconciliation Commission; 3. present-day language as determined and constituted by the plurality of languages, between the Scylla and Charybdis of “Globish” and “ontological nationalism”. John L. Austin’s theory of performative speech acts as laid down in How to do Things With (...) Words serves as a contemporary frame of reference throughout the argument. (shrink)
