This is plain dishonest. Wikipedia has dozens of pages on holes, some of which are cultural items and the author cherry-picked two in order to make his point: https://en.wikipedia.org/wiki/Holes
Moreover, the SEP's description of a hole is so arrogant and condescending it's painful:
> Naive, untutored descriptions of the world treat holes as objects of reference, on a par with ordinary material objects....
Spare me.
