It seems to me that Jon Barwise may be mistaken in thinking that Godel was
referring to non-standard analysis in his remark, made in 1961. It was in
1961 that Robinson published his first paper on non-standard analysis.
This makes it dubious as to whether Godel would have known of it at the
time he was writing. So Godel may have been referring to the epsilon-delta
replacement for the notion of infinitesimal, not to Robinson's
reconstruction of it.
