The above passage was found in a search for thoughts of Heinz Pagels
on "perfect symmetry" (the title of one of his books). The "If all" part is,
however, apparently not by Pagels. That part seems to have been
online only in an NYU file that can no longer be accessed.
For perfect symmetry with structure, see (for instance)
Go Set a Structure (July 14, 2015) and Tombstone (July 16, 2015).
