he was in mid-space: and so it was necessary for him
to pass through intervening space.
_I answer that,_ As was observed above in the preceding article, the
local motion of an angel can be continuous, and non-continuous. If it
be continuous, the angel cannot pass from one extreme to another
without passing through the mid-space; because, as is said by the
Philosopher (Phys. v, text 22; vi, text 77), "The middle is that into
which a thing which is continually moved comes, before arriving at the
last into which it is moved"; because the order of first and last in
continuous movement, is according to the order of the first and last
in magnitude, as he says (Phys. iv, text 99).
But if an angel's movement be not continuous, it is possible for him
to pass from one extreme to another without going through the middle:
which is evident thus. Between the two extreme limits there are
infinite intermediate places; whether the places be taken as divisible
or as indivisible. This is clearly evident with regard to places which
are indivisible; because between every two points that are infinite
intermediate points, since no two points follow one another without a
middle, as is proved in Phys. vi, text. 1. And the same must of
necessity be said of divisible places: and this is shown from the
continuous movement of a body. For a body is not moved from place to
place except in time. But in the whole time which measures the
movement of a body, there are not two "nows" in which the body moved
is not in one place and in another; for if it were in one and the same
place in two "nows," it would follow that it would be at rest there;
since to be at rest is nothing else than to be in the same place now
and previously. Therefore since there are infinite "nows" between the
first and the last "now" of the time which measures the movement,
there must be infinite places between the first from which the
movement begins, and the last where the movement ceases. This again is
made evident from sensible experience. Let there be a body of a palm's
length, and let there be a plane measuring two palms, along which it
travels; it is evident that the first place from which the movement
starts is that of the one palm; and the place wherein the movement
ends is that of the other palm. Now it is clear that when it begins to
move, it gradually quits the first palm and enters the second.
According, then, as the magnitude of the palm is divided, even so are
the
