  The natural modal epistemic counterpart of the evidence assertion  \(t : F\) is \(\Box F\), read for some x,  x:\(F\). This observation leads to the notion of  forgetful projection which replaces each occurrence of  \(t : F\) by \(\Box F\) and hence converts a  Justification Logic sentence \(S\) to a corresponding Modal  Logic sentence \(S^{o}\). The forgetful  projection extends in the natural way from sentences to logics.
