 The interest of studying combinations of logics may thus be seen as a reflex of the pluralist view of contemporary logical research. Indeed, this kind of bridge axioms can, in principle, connect completely distinct logics. Van Benthem (2006) suggests that combining logics may lead to the emergence of new phenomena, depending on the mode of combination, and moreover, it may work as an inspiration (and perhaps as a model) for the study of combining epistemic notions. He even suggests that the compartmentalization of logic into subfields as ‘modal’, ‘temporal’, ‘epistemic’, ‘doxastic’, ‘erotetic’ or ‘deontic’ logic has been harmful to Philosophical Logic.
