Keep Changing Your Beliefs, Aiming for the Truth.

We investigate the process of truth-seeking by iterated belief revision with higher-level doxastic information. We elaborate further on the main results in Baltag and Smets (Proceedings of TARK, , Proceedings of WOLLIC'09 LNAI 5514, ), applying them to the issue of convergence to truth. We study the...

Sumario:We investigate the process of truth-seeking by iterated belief revision with higher-level doxastic information. We elaborate further on the main results in Baltag and Smets (Proceedings of TARK, , Proceedings of WOLLIC'09 LNAI 5514, ), applying them to the issue of convergence to truth. We study the conditions under which the belief revision induced by a series of truthful iterated upgrades eventually stabilizes on true beliefs. We give two different conditions ensuring that beliefs converge to 'full' (complete) truth, as well as a condition ensuring only that they converge to true (but not necessarily complete) beliefs.
