Paul Aczel was the origionator of the hyper-set idea.
I got the reference from the following book (which Onar
recommended)
Goertzel, Ben, (1994) CHAOTIC LOGIC: LANGUAGE THOUGHT, AND REALITY
FROM THE PERSPECTIVE OF COMPLEX SYSTEMS SCIENCE. Plenum Press, New
York. ISBN 0-306-44690-1.
In the book, Ben Goertzel mentioned that he found Paul Aczel's book
in the MIT bookstore in Cambridge Massachusetts.
