Another writer influenced by Scott was James Van Aken, whose
"Axioms for the set-theoretic hierarchy," JSL 51 (1986),
pp. 992-1004
presents a variation on Scott's theme, with some discussion of
their intuitive motivation. Van Aken dubs the relation of later
to early stages "presupposition"; my own feeling is that his paper
represents something of a high-water mark for the metaphysical
view of the iterative hierarchy-- a fe years later, George Boolos
"Iteration Again," Philosophical Topics 17 (1989), pp. 5-21;
repr. in Boolos's "Logic, Logic, and Logic"
reminded philosophers of the role of "limitation of size," suggesting
that this was independent of the iterative conception.
Scott's magical way of obtaining induction-on-membership (rank
induction) from assumptions that don't SEEM to include it has
influenced other people as well. Cf. the article by Geoffrey Hellman
in Sher & Tieszen, eds., "Intuition and Logic."
