The double entendre of "having studied Agrippa" in the footnotes is probably going to go unnoticed unless someone mentions it here. Contemporary to the cited Camillo Agrippa, fencing master, was Henrichus Cornelius Agrippa, whose collections on philosophy and occultism are much more relevant to the topic. H.C. Agrippa's work is still considered authoritative in its fields: the numbers represent the ideas, which were both created in the first moments by God. the difference between set of reals and set of integers might have a correlation to the difference between the set of all expressible concepts, and (the smaller) set of actually meaningful concepts. Maybe some computability theory could be tossed in there too.
