Sense-objects, therefore, occupy a rank intermediary between matter
and form itself.[83] They no doubt appear, because they are derived
from intelligible entities; but they are deceptive, because the matter
in which they appear does not really exist.[84] Each of them becomes
a magnitude, because it is extended through the power of the entities
that appear here below, and which locate themselves here. Thus we
have, in every direction, the production of an extension; and that
without matter undergoing any violence, because (potentially) it is all
things. Everything produces its own extension by the power it derives
from the intelligible entities. What imparts magnitude to matter is
the appearance of magnitude, and it is this appearance that forms our
earthly magnitude. Matter yields itself everywhere entirely to the
extension it thus, by the universal appearance of magnitude, is forced
to take on. Indeed, by its nature, matter is the matter of everything,
and consequently is nothing determinate. Now that which is nothing
determinate by itself could become its opposite (of what it is), and
even after thus having become its own opposite, it is not yet really
this opposite; otherwise this opposite would be its nature.[85]
