It may be objected that it may happen that the soul will divide and
develop something which was unitary. This thing must then already
have been divided in intelligence, but such a division is more like
an impression. As anteriority or posteriority in ideas does not
refer to time, so also will the mental conception of anteriority and
posteriority not be subject to temporal conditions, but refer to order
(which presides over intelligible things). For instance, on considering
a tree's order that extends from the roots to the tree-top, priority
and posteriority exists only under the relation of order, inasmuch as
the whole plant is perceived at one single glance.
