case is not brought to a penetration of dimensions and vacuity,
except in the utmost limits of condensation and rarefaction;
whereas, these motions stop far short of those limits, as being no
more than appetites which bodies have of continuing themselves in
their own consistencies or dimensions, and not suddenly departing
from them, unless altered by gentle means and by consent. But it is
much more necessary, as being a thing of great consequence, to
observe that violent motion, as it is called, is no other than this
very motion of liberty, tending from compression to relaxation.
For, in all simple protrusion, or flight through the air, there is
no tendency to motion or change of place before the parts of See
the Author's History of Condensation oud Rarefaction/ the body
suffer preternaturally, and are compressed by the impelling force;
whence it is that some parts successively pressing against the
rest, the whole body is driven off, or protruded; and not only in a
progressive, but at the same time in a rotatory or revolating
motion, so as that by this means also the parts may free
themselves, or suffer more equally. Let the fourth motion be the
motioa of extension; which is, in some measure, the opposite to the
motion of liberty; for, in the motion of liberty, bodies avoid,
dread, and fly from a new dimension, or a new degree of dilatation
or contraction, and endeavour, with all their force, to recover
their former state; whereas, on the contrary, in the motion of
extension, bodies affect a new dimension, and sometimes willingly
and hastily aspire to it, even with a violent endeavour, as we see
in gunpowder. And the most powerful, or at least the most common,
though not the only instruments of this motion, ...
