You're a superstar Hans, thanks very much for the quick turnaround.

That the Ideas are themselves manifestations (of the Idea-Idea) and
that the Idea-Idea is a-kind-of Manifestation-Idea—which is a-kind-of
itself, so that the system is completely self-describing— would have
been appreciated by Plato as an extremely practical joke [Plato]. --
