) in a union of bodies; but
this union, although there is a continual change of bodies, will
(by our hypothesis) be maintained; the individual, therefore,
will retain its nature as before, both in respect of substance
and in respect of mode. Q.E.D.
[L.V] If the parts composing an individual become greater or less
but in such proportion, that they all preserve the same mutual
relations of motion and rest, the individual will still
preserve its original nature, and its actuality will not
be changed.
Proof.- The same as for the last [L.iv] .
[L.VI] If certain bodies composing an individual be compelled to
change the motion, which they have in one direction, for
motion in another direction, but in such a manner, that
they be able to continue their motions and their mutual
communication in the same relations as before, the
individual will retain its own nature without any change
of its actuality.
Proof.- This proposition is self-evident, for the individual
is supposed to retain all that, which, in its definition,
we spoke of as its actual being.
[L.VII] Furthermore, the individual thus composed preserves its
nature, whether it be, as a whole, in motion or at rest,
whether it be moved in this or that direction; so long
as each part retains its motion, and preserves its
communication with other parts as before.
