Single Idea 16584
[filed under theme 9. Objects / C. Structure of Objects / 7. Substratum
]
Full Idea
When the substratum thesis is grounded on the idea that the ingredients must endure through the change, if they are to play a causal role, then it is natural to suppose that quite a lot of the ingredients must endure.
Gist of Idea
If a substrate gives causal support for change, quite a lot of the ingredients must endure

A Reaction
Aristotle sharply distinguishes alteration from substantial change, but as the substrate gets thinner, the boundary between those two would blur.
