 The ensuing anarchy can be mitigated to some extent, e.g., by assuming what Nolan 1997 calls the Strangeness of Impossibility Condition (SIC): any possible world, however weird, should be closer to any possible world \(w\) than any impossible world is to \(w\). Reality will be turned upside down before logical laws or mathematical truths abandon us. Then it is plausible that the Lewis-Stalnaker principles will still hold whenever the relevant antecedent is possible. For then we will consider only the closest antecedent-worlds when we evaluate the conditional, all of which will be possible worlds: the impossible ones will be too far away (Berto et al. 2018).
