Thanks Lou, you are surely right to point out the object-nature of concepts.
>There is no escape from sooner or later realizing that 2 exists only
in the mind or in the Mind.
Indeed. Our minds are full of such concepts. It seems that one of the
important activities of the mind is to generate 'things' from the
processes that impinge upon us. This makes living our lives much simpler
(we don't need to set about curating the collection of all couples).
>Mind as eigenform never happens except at the limit where
self-reference occurs.
I found it useful to read your paper on that is to be found at
eigenforms http://homepages.math.uic.edu/~kauffman/Eigen.pdf.
