 This very general ordering of impossibilities, albeit intuitive, may not be fully satisfying. A general qualm concerns the SIC principle itself. For one may claim that, intuitively, some slightly deviant impossible worlds may be more similar to the actual world @ than some possible but very weird worlds. For instance, the impossible world \(t\) above, which is like @ except for Franz’s wearing an inconsistent T-shirt, may look more familiar than a world which is logically possible, but where the laws of physics are turned upside down. Several authors (Nolan 1997, Vander Laan 2004, Bernstein 2016) have proposed putative counterexamples to SIC along these lines.
