begin{remark}
The embedding introduces the notion of \emph{proper} maps from
individual terms to propositions.
Such a map is proper if and only if for all proper individual terms its truth evaluation in the
actual state only depends on the urelements corresponding to the individuals the terms denote.
Proper maps are exactly those maps that - when used as matrix of a lambda-expression - unconditionally
allow beta-reduction.

abstract objects and ordinary objects. Furthermore the axioms about
concreteness have to be satisfied. This is achieved by introducing an
uninterpreted constant @{term "ConcreteInWorld"} that determines whether
an ordinary object is concrete in a given possible world. This constant is
axiomatized, such that all ordinary objects are possibly concrete, contingent
objects possibly exist and possibly no contingent objects exist.
