 Indisputably, a large number of true generics of the form “Ks Φ” are such that, if things go normally for a given K, then it has the property Φ. However, there would seem to also be a number of true generics which do not fit this profile: “ducks lay eggs”, “lions have manes”, “mosquitoes carry the West Nile virus”, and “sharks attack swimmers”. The last two generics present a significant difficulty for normalcy-based accounts, since it is surely not normal for a mosquito to carry the virus, nor is it normal for a shark to attack a bather. For generics such as “ducks lay eggs” and “lions have manes”, several theorists have argued that the domain of discourse is restricted so that we are talking about only the female ducks and the male lions respectively, and thus have aimed to rescue normalcy-based approaches from this criticism (e.g., Pelletier and Asher 1997), since perhaps it is abnormal for a given female duck to fail to lay eggs. Pelletier and Asher suggest that a generic can be restricted to a subkind of the kind in question in this way; that is, “ducks lay eggs” means female ducks lay eggs because female ducks constitute a subkind of the kind ducks.
