Actualism I 5
Definition Actuality/Existence/Being/Frege/Russell/Quine/Boer: Thesis: There is no distinction between existence and being. (> Non-existence, non-existencing). That is, there are no non-existent things.
Nominalism is, of course, an actualism.
I 5
Tolerant actualism/Boer: admits, e.g. that there are non-actual states. E.g. causally not effective non-concreted individuals. For example, non-exemplified properties.
Intentional relation/tolerant actualism: allows that it is only possible that we participate in such relations. Principle (DI):

(DI) 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.
I 6
Therefore (DI) can be accepted by actualists as well as by non-actualists.
I 5
Scientific Camp: Plantinga: (1974) is a liberal actualist without nominalist scruples - also allows properties, relation and propositions.
