题目: Intentions in Intelligent Interaction

主讲：Professor Ahti-Veikko Pietarinen

主持人：江怡教授

摘要：

Is game theory also a general theory of rational communicative interaction? Which of our linguistic and non-linguistic competencies in communication can be modelled as strategic reasoning? If communicative action is not just a move but a belief, game theories need become theories of choice concerning mental, cognitive and semantic entities. Only showing how Grice's maxims emerge from endogenous meaning does not get us to the bottom of the issue. Merely treating beliefs as variants of Bayesian updates on incomplete information is equally inadequate. The problems are: (i) how to encode intentions that are of the same nature as abductive reasoning, (ii) how new conceptual categories are created, and (iii) how to cope with ex ante fundamental uncertainties when the problem contexts are neither well-structured nor invariant. These are very different issues from what have traditionally been perceived as species of inductive problems or those of rationality in communication.
