Single Idea 6771
[filed under theme 26. Natural Theory / B. Natural Kinds / 1. Natural Kinds
]
Full Idea
It seems clear that in some cases one natural kind may be a subkind of another, while in other cases natural kinds may overlap without one being the subkind of another.
Gist of Idea
Natural kinds may overlap, or be sub-kinds of one another

A Reaction
Given the enormous difficulty of pinpointing natural kinds (e.g. Idea 6768), it is hard to know whether the comment is correct or not. Ellis says natural kinds come 'in hierarchies', which would make subkinds normal, but overlapping unlikely.
