Single Idea 16190

[filed under theme 4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula ]

Full Idea

In accordance with the Barcan Formula we assume that if it is possible that Wittgenstein should have had a child, then something or other is possibly Wittgentein's child.

Clarification

Wittgenstein had no children

Gist of Idea

BF implies that if W possibly had a child, then something is possibly W's child

Source

Ori Simchen (The Barcan Formula and Metaphysics [2013], §5)

Book Ref

-: 'Theoria' [-], p.20


A Reaction

Put like this it sounds unpersuasive. What is the something or other? Someone else's child? A dustbin? A bare particular? Wittgenstein's child? If it was the last one, how could it be Wittgenstein's child while only possibly being that thing?

The Barcan Formulas are orthodox, but clash with the attractive Actualist view [Simchen]
Serious Actualism says there are no facts at all about something which doesn't exist [Simchen]
BF implies that if W possibly had a child, then something is possibly W's child [Simchen]
