Single Idea 8291

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

Full Idea

A principle of individuation tells us what is to count as one instance of a given kind, such as one ship. A criterion of identity is what makes for the identity or diversity of items of a given kind, to distinguish this ship from that ship.

Gist of Idea

Individuation principles identify what kind it is; identity criteria distinguish items of the same kind

A Reaction

So individuation picks out type/qualitative identity, and identifying picks out token/numerical identity. This agrees with Idea 7926, but is a shift from the usage Lowe mentions in Idea 8290. Common usage makes the technical terms unclear.
