Full Idea
Maybe a substance is not itself a bundle of properties, but a sum or sequence of bundles of properties, a bundle of bundles of properties (which 'perdures' rather than 'endures').
Clarification
To 'perdure' is to have temporal parts, rather than fixed unity over time
Gist of Idea
A substance might be a sequence of bundles, rather than a single bundle

A Reaction
There remains the problem of deciding when the bundle has drifted too far away from the original to perdure correctly. A caterpillar can turn into a butterfly (which is pretty bizarre!), but not into a cathedral. Why? She says this idea denies change.
