Intercultural aspects of the speech act of promising from a relevance theoretic point of view

This study on the Speech Act of Promising builds on an article by Egner (2005) which claims that in many African Societies a promise is most often made not to be committed to its content but to be polite and save one's own or the addressee's face. While Egner opts for a Speech Act Theory approach to explain the phenomenon and comes to the conclusion that the speech act of promising may occur minus commitment, thus refuting the standard SAT claim, I have opted to treat the issue within Relevance Theory and claim that a true speech act of promising cannot be without commitment since it is a performative and institutional speech act which has to be committed by its very nature. I have rather explained that the concept PROMISE can be used as an ad hoc concept PROMISE* which conveys a speech act of "saying that" and which is a broadened version of the encoded concept to make commitment optional and include issues of politeness and face saving. While Egner claims that a committed speech act can be determined by linguistic indication most of the time I claim that the intended interpretation falls out naturally from the relevance theoretic comprehension procedure which is: "Follow the path of least effort in determining cognitive effects and stop when your expectation of relevance is fulfilled". Unlike Egner I claim that at the root of using non-committed promises as a face saving device are shame oriented cultures that need these kinds of mechanisms for politeness more than guilt oriented cultures.
