regions and the inclusion relation between
regions, Whitehead uses what he calls the method of

This mimics the construction of R using nested intervalls.
However: the filtration process is not done coordinatewise!

- Lebesgue measure: Mereological,
individual points do not count.
- Lebesgue number (for compact metric spaces: for every open covering, there exists a real number
δ such that the δ-neighborhood of any point lies is contained in one of the given sets.
