 Despite his spirited defence of Frege’s and Husserl’s favourite whipping boy, Meiland believes that Erdmann’s psychologism must overcome some further difficulties before it can become fully respectable. The main problem is that Erdmann allows for the possibility that the laws of logic could change, that there could be a different logic, a logic that conflicts with our present one. Yet it is hard to see how Erdmann could be entitled to make such claim. On his own premises, our present logic defines the limits of the thinkable. And this can only mean that a radically different logic must be unthinkable for us. Put differently, Erdmann owes us an explanation of how we could ever come to believe that a different logic is possible (1976, 337).
