In its higher reaches, which posit sets of huge cardinalities, set theory is just a fairy story.

A Reaction
You can't say the higher reaches are fairy stories but the lower reaches aren't, if the higher is directly derived from the lower. The empty set and the singleton are fairy stories too. Bostock says the axiom of infinity triggers the fairy stories.
