But the structure which determines the sum is the structure of the part-states as constituted by
World states, and this is
inaccessible from within the
World, that is,
inacessible to World parts.
No part can
fully represent the
whole, so no part of the
World can ever
completely reveal the way it
depends on the states of the World. Thus, from within the World, the
parts of the World do not reveal enough to
completely determine their
sums, even less that sum
which is the whole.
