Scholastics treat relations as two separate predicates of the relata
|
9. Objects / A. Existence of Objects / 4. Individuation / a. Individuation
|

|
If you individuate things by their origin, you still have to individuate the origins themselves

9. Objects / A. Existence of Objects / 4. Individuation / d. Individuation by haecceity
|

|
Haecceity as property, or as colourless thisness, or as singleton set
|
9. Objects / B. Unity of Objects / 2. Substance / a. Substance

|
13101

Necessity-of-origin won't distinguish ex nihilo creations, or things sharing an origin
|
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
|
13081
|
Even extreme modal realists might allow transworld identity for abstract objects

We can go beyond mere causal explanations if we believe in an 'order of being'
