Intends to say many controversial things about spacetime. So leave objections til the end.

The debate we will be looking at:  holonomies (Belot, Healey) vs. fibre bundle substantivalism (Arntzenius, Nounou).

Aharonov-Bohm effect used to argue that holonomies about closed paths to be the fundamental physical quantities.

Arntzenius: Fibre bundles *really exist* and their parts.

Obviously dimensionality will be distinct here.
