9. Objects / A. Existence of Objects / 4. Individuation / a. Individuation
Indiscernibility is a necessary and sufficient condition for identity
9. Objects / A. Existence of Objects / 4. Individuation / e. Individuation by kind
Brody bases sortal essentialism on properties required throughout something's existence
9. Objects / C. Structure of Objects / 2. Hylomorphism / a. Hylomorphism
Modern emphasis is on properties had essentially; traditional emphasis is on sort-defining properties
9. Objects / D. Essence of Objects / 5. Essence as Kind
A sortal essence is a property which once possessed always possessed
Maybe essential properties are those which determine a natural kind?
9. Objects / D. Essence of Objects / 6. Essence as Unifier
De re essentialism standardly says all possible objects identical with a have a's essential properties
9. Objects / D. Essence of Objects / 7. Essence and Necessity / a. Essence as necessary properties
An object having a property essentially is equivalent to its having it necessarily
Essentially, a has P, always had P, must have had P, and has never had a future without P
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
Essentialism is justified if the essential properties of things explain their other properties
9. Objects / D. Essence of Objects / 12. Essential Parts
Mereological essentialism says that every part that ensures the existence is essential
9. Objects / E. Objects over Time / 12. Origin as Essential
Interrupted objects have two first moments of existence, which could be two beginnings
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
a and b share all properties; so they share being-identical-with-a; so a = b
10. Modality / E. Possible worlds / 3. Transworld Objects / b. Rigid designation
Identity across possible worlds is prior to rigid designation
