A philosopher who holds the doctrine of actualism; one who believes only actual things exist and not abstract possibilities or potential entities.
From 'actualism' plus '-ist' (one who practices or believes in). Created through standard English word formation combining a doctrine with the agent suffix.
Actualists argue that fictional characters like Harry Potter don't literally exist anywhere, not even in 'possible worlds'—which puts them at odds with logicians who need such worlds to make their formal systems work.
