[filed under theme 10. Modality / E. Possible worlds / 1. Possible Worlds / d. Possible worlds actualism ]

Full Idea

Serious Actualism is the view that in possible circumstances in which something does not exist there are no facts about it of any kind, including its very non-existence

Gist of Idea

Serious Actualism says there are no facts at all about something which doesn't exist

Source

Ori Simchen (The Barcan Formula and Metaphysics [2013], §1 n4)

Book Ref

-: 'Theoria' [-], p.4


A Reaction

He suggests that the Converse Barcan Formula implies this view. It sounds comparable to the view of Presentism about time, that no future or past truthmakers exist right now. If a new square table were to exist, it would have four corners.
