to be circular, the meer ſpherical figure is the moſt perfect

SIMP. The moſt that ought to be granted upon this, would be,
that it may hold true in one ſingle motion, but in three different
motions, in my opinion, and that of the Author, it is
ble; as he going on, proſecuting the objection, writes in the
lowing words. Let us ſuppoſe, with Copernicus, that the Earth
moveth of its own faculty, and upon an intrinſick principle from
Weſt to Eaſt in the plane of the Ecliptick; and again, that it alſo
by an intrinſick principle revolveth about its centre, from Eaſt to
Weſt; and for a third motion, that it of its own inclination
cteth from North to South, and ſo back again. It being a
nuate body, and not knit together with joints and flections, our
fancy and our judgment will never be able to comprehend, that
one and the ſame natural and indiſtinct principle, that is, that
one and the ſame propenſion, ſhould actuate it at the ſame inſtant
with different, and as it were of contrary motions. I cannot
lieve that any one would ſay ſuch a thing, unleſſe he had
took to maintain this poſition right or wrong.

oppoſe a poſition, which he hath not well underſtood; for theſe
are not the motions which Copernicus aſſignes to the Earth.
Where doth he find that Copernicus maketh the annual motion
by the Ecliptick contrary to the motion about its own centre? It
muſt needs be that he never read his Book, which in an hundred
places, and in the very firſt Chapters affirmeth thoſe motions to
be both towards the ſame parts, that is from Weſt to Eaſt.
But without others telling him, ought he not of himſelf to
prehend, that attributing to the Earth the motions that are ta
ken, one of them from the Sun, and the other from the
mum wobile, they muſt of neceſſity both move one and the ſame
