[catalogued under 9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind]

Full Idea

In Wiggins's theory, necessity carries over from the kind to constitution. If Toby is necessarily a dog and 'dog' is a natural kind term, then Toby necessarily has the constitution of a dog, the features of which make up the real essence of being a dog.

Gist of Idea

A thing is necessarily its highest sortal kind, which entails an essential constitution

A Reaction

The essence will then presumably consist of all and only the characteristics which are shared by all dogs whatsoever. So how do you decide the borderline between wolf and dog? Why isn't a wolf a dog?
