Abstract. We define the notion of a model of higher-order modal logic
in an arbitrary elementary topos E. In contrast to the well-known interpretation of (non-modal) higher-order logic, the type of propositions is not interpreted by the subobject classifier ΩE , but rather by a suitable complete Heyting algebra H.
The canonical map relating H and
