Cartesianism/Dualism/Boer: a dualist might say that some things are localized in time, but not in space.
Theorem (T1): follows from (P ^) and (D1)
(T1) Everything that participates in the world exists.
(D1) Definition "X participates/participation in the world": If X is an individual, then it exists localized in the space time, if X is a proposition, it exists and is true. If X is a state, it exists and persists. If X is a property or relation, then it exists and is exemplified. If X is an event, then it exists and X occurs.
Non-actuality/Boer: would say that non-existent things can no longer participate in the world, as unexamplified properties.
Therefore (D1) can be accepted by actualists as well as by non-actualists.
The converse of (T1) is controversial:
