[FOM] Possible worlds

[Stephen Pollard]

Consider the following two counterfactuals.

If FLT were false, then no argument for it would be sound.
If FLT were false, then Andrew Wiles would deserve eternal fame.

Folks who feel that these statements have different truth values are,  
naturally, dissatisfied with semantics that assign them the same  
truth value. Impossible worlds provide one way of responding to this  
situation. A good resource is Volume 38, Number 4 of the Notre Dame  
Journal of Formal Logic (available at projecteuclid.org).
