A Reaction

I am a fan of this view, despite being cautious about claims that natural kinds have necessary identity. Why are the essences active? That is the old Greek puzzle about the origin of movement. And why are natural kinds stable?

Natural kinds are distinguished by resting on essences [Ellis]
The properties of an electron can't be explained just as 'clustering' [Chakravartty on Boyd]
Properties cluster together, either because of intrinsic relations, or because of an underlying process [Boyd, by Chakravartty]
Natural kinds, such as electrons, all behave the same way because we divide them by dispositions [Mumford]
There is nothing more to a natural kind than a real pattern in nature [Ladyman/Ross]
Some kinds, such as electrons, have essences, but 'cluster kinds' do not [Chakravartty]
Concepts for species are either intrinsic structure, or relations like breeding or ancestry [Koslicki]
Kinds are fixed by the essential properties of things - the properties that make it that kind of thing [Eagle]
