1principle of the Elements. Which is manifeſt, for that if I aske
the
Peripatetick, if, being of opinion that Cœleſtial bodies are
incorruptibe
and eternal, he believeth that the Terreſtial Globe
is
not ſo, but corruptible and mortal, ſo that there ſhall come a
time
, when the Sun and Moon and other Stars, continuing their
beings
and operations, the Earth ſhall not be found in the
World
, but ſhall with the reſt of the Elements be deſtroyed
and
annihilated, I am certain that he would anſwer me, no:

therefore
generation and corruption is in the parts and not in the
whole
; and in the parts very ſmall and ſuperficial, which are,
as
it were, incenſible in compariſon of the whole maſſe.
And
becauſe
Ariſtotle deduceth generation and corruption from the
contrariety
of ſtreight motions, let us remit ſuch motions to the
parts
, which onely change and decay, and to the whole Globe
and
Sphere of the Elements, let us aſcribe either the circular
tion
, or a perpetual conſiſtance in its proper place: the only
affections
apt for perpetuation, and maintaining of perfect order.
This which is ſpoken of the Earth, may be ſaid with the ſame
reaſon
of Fire, and of the greateſt part of the Air; to which

Elements
, the Peripateticks are forced to aſcribe for intrinſical
and
natural, a motion wherewith they were never yet moved,
nor
never ſhall be; and to call that motion preternatural to them,
wherewith
, if they move at all, they do and ever ſhall move.
This I ſay, becauſe they aſſign to the Air aud Fire the motion
upwards
, wherewith thoſe Elements were never moved, but
only
ſome parts of them, and thoſe were ſo moved onely in
der
to the recovery of their perfect conſtitution, when they were
out
of their natural places; and on the contrary they call the
circular
motion preternatural to them, though they are thereby
inceſſantly
moved: forgeting, as it ſeemeth, what Ariſtotle oft
culcateth
, that nothing violent can be permanent.
Ariſt. & Ptolomey

strial
Globe
veable

*The word is, all'
ingiù
