Summary/Abstract: In this paper, we bring up the problem of logical omniscience in epistemic logic. One way ofavoiding the problem is through Rantala models, where non-normal worlds are introduced. Suchmodels are vulnerable to criticism, as we show. One of many issues that occur is the Bjerring result,which states that incorporating non-normal worlds makes the agent logically incompetent. For this reason, we propose a different solution based on positional logics.
