Objects in themselves are not known to us at all [Kant]
The a priori concept of objects in general is the ground of experience [Kant]
9. Objects / A. Existence of Objects / 5. Individuation / a. Individuation
A principle of individuation may pinpoint identity and distinctness, now and over time [Mackie,P]
Individuation may include counterfactual possibilities, as well as identity and persistence [Mackie,P]

A haecceity is the essential, simple, unanalysable property of being-this-thing [Mackie,P]

A substance could exist as a subject, but not as a mere predicate [Kant]

The substance, once the predicates are removed, remains unknown to us [Kant]

There are problems both with individual essences and without them [Mackie,P]
9. Objects / D. Essence of Objects / 5. Essence as Kind

Why are any sortals essential, and why are only some of them essential? [Mackie,P]

The Kripke and Putnam view of kinds makes them explanatorily basic, but has modal implications [Mackie,P]
9. Objects / E. Objects over Time / 1. Objects over Time
An a priori principle of persistence anticipates all experience [Kant]
9. Objects / E. Objects over Time / 12. Origin as Essential
Origin is not a necessity, it is just 'tenacious'; we keep it fixed in counterfactual discussions [Mackie,P]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
The Identity of Indiscernibles is true of concepts with identical properties, but not of particulars [Kant, by Jolley]
If we ignore differences between water drops, we still distinguish them by their location [Kant]
