 Possible worlds are helpful here, because they allow us to consider, say, worlds in which things go as normally as possible for a given tiger, even if life is actually quite abnormal for that tiger. For example, Asher, Morreau, and Pelletier argue that “Ks Φ” is true iff for each individual K, the most normal worlds for that K (according to a contextually determined ordering base), are such that that K Φs (Asher and Morreau 1995; Pelletier and Asher 1997). Glossed in more intuitive terms, the account states that a generic “Ks Φ” is true iff each individual K would have the property Φ if all were to go as normally as possible for that K with respect to the relevant property. Thus, while in actuality some dogs are three legged, one might suppose that, had things gone more normally for each of those dogs with respect to how many legs they have, they would have had four legs.
