 The logical implications of maintaining this fixed perspective in the actual world are quite dramatic. First and foremost, it undermines the motivation for MSA entirely and, with it, the arguments against the validity of the principles \(\Box\Diamond,\) 4, B, 5, and the rule of necessitation Nec*. All of those can therefore be embraced without the existence qualifications of \(\Box\Diamond_A,\) 4\(_A\), B\(_A\), 5\(_A\), and \(\textbf{Nec}_A\). Substituting the unqualified principles and the rule  Nec*  in their place results in what might be called a fully perspectivalist modal logic A* for the strict actualist that restores everything that was lost in Prior’s Q, and does so without the expressive restrictions of Kripke’s KQML.
