Full Idea
Talk about particulars remaining the same and yet lacking their usual capacities and powers is at once to assert and deny that a certain object or sample of material has a given nature.
Gist of Idea
To say something remains the same but lacks its capacities and powers seems a contradiction

A Reaction
They imply that this is a contradiction, and hence impossible. So what do we say about something in which the powers fade? Do they both retain and lose their identity? Or can we separate essence from identity?? Aha!
