Re: "schizophrenic" reference

["Prof. Peter Johnstone" <P.T.Johnstone@dpmms.cam.ac.uk>]

I don't claim credit (if that's the right word) for
introducing this use of "schizophrenic". I got it from
an early draft of Harold Simmons's paper "A couple of
triples" -- though Harold changed his terminology before
the published version appeared (Topology Appl. 13, 1982).
In "Sheaves in Geometry and Logic" (p. 280), Mac Lane and
Moerdijk credit John Isbell with having introduced the term,
but I don't know of any publication where John used it.
