      §14. Thirdly, The parts of pure Space, are immovable, which fol-
lows from their inseparability; Motion being nothing but change of
distance between any two things: But this cannot be between
Parts that are inseparable; which therefore must needs be at
perpetual rest one amongst another.
Thus the determined Idea of simple Space distinguishes it plainly,
and sufficiently from Body; since its Parts are inseparable, im-
movable, and without resistance to the Motion of Body.
