Jaśkowski’s discussive logic D2 was formulated with the help of the modal logic S5 as follows (see [7, 8]): $${A \in {D_{2}}}$$ iff $${\ulcorner\diamond{{A}^{\bullet}}\urcorner \in {\rm S}5}$$, where (–)• is a translation of discussive formulae from Ford into the modal language. We say that a modal logic L defines D2 iff $${{\rm D}_{2} = \{A \in {\rm For^{\rm d}} : \ulcorner\diamond{{A}^{\bullet}}\urcorner \in {\it L}\}}$$. In [14] and [10] were respectively presented the weakest normal and the… Expand
