I wasn't aiming for an attribution of credit -- only for a citation of use of the term in the accessible literature. Certainly I have, over the years, heard at least Isbell and Lawvere -- and others -- refer to schizophrenic objects, schizoid objects, objects with "split" -- or "multiple", or = "more than one" -- personality, and the like. How far back, "over the years"? -- Probably at least to the early 'seventies, quite possibly earlier. Cheers, -- Fred [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
