Full Idea
I won't discuss whether points are unities or simple terms, but whether space is an aggregate of them. ..There is no geometry without points, nothing against them, and logical reasons in their favour. Space is the extension of the concept 'point'.
Gist of Idea
Space is the extension of 'point', and aggregates of points seem necessary for geometry
