Truth, Dialogue, and Logic (Part II)

Speaker(s) : Sanjay Modgil (Kings College London)

In the second lecture, I suggest that we look to the study of non-monotonic logics, when articulating the inferential norms that govern these processes of dialectical inquiry. There is a growing body of research that aims at formalising individual agent non-monotonic reasoning in terms of the dialectical exchange of arguments. Given the above account of inquiry broadly construed, we are then faced with two challenges.
Firstly, integration of these dialectical formalisations of non-monotonic logics with probabilistic (in particular Bayesian) inference; one that is suited to modelling the predictive processing account of cognition.
Secondly, reformulating these dialectical formalisations of individual agent reasoning in terms of normative constraints on speech acts, so as to obtain communicative accounts of distributed non-monotonic reasoning.
I focus on progress towards meeting this second challenge, by pointing to work on ASPIC+ formalisations of non-monotonic reasoning and dialogical developments of ASPIC+. I argue for the importance of this ‘dialogical turn’ given some of the ethical challenges raised by contemporary developments in Artificial Intelligence, and wider concerns about our "post-truth" predicament.
