Additional Knowledge

Proposition: For proving with knowledge K the goal G, it suffices to prove G with additional knowledge F, if F holds in every domain in which (some of) the formulas in K holds.

K union {F}
(F holds in every domain in which K holds).

Derive new knowledge F from (a subset of) K.
