1and fixed Stars may ſtand immoveable, in caſe the Earth ſhould
move
: the matter of fact in diſpute is, to which of them we may
with
moſt convenience aſcribe motion, and to which reſt.
Natural
reaſon
dictates, that motion ought to be aſſigned to the bodies,
which
in kind and eſſence moſt agree with thoſe bodies which do
undoubtedly
move, and reſt to thoſe which moſt diſſent from them;
and
in regard that an eternal reſt and perpetual motion are moſt
different
, it is manifeſt, that the nature of the body always
able
ought to be moſt different from the body alwayes ſtable.
Therefore, in regard that we are dubious of motion and reſt,
let
us enquire, whether by the help of ſome other eminent
on
, we may diſcover, which moſt agreeth with the bodies
ly
moveable, either the Earth, or the Sun and fixed Stars.
But ſee
how
Nature, in favour of our neceſſity and deſire, preſents us
with
two eminent qualities, and no leſs different than motion and
reſt
, and they are light and darkneſs, to wit, the being by nature
moſt
bright, and the being obſcure, and wholly deprived of light:
the
bodies therefore adorned with an internal and eternal
dour
, are moſt different in eſſence from thoſe deprived of light:
The
Earth is deprived of light, the Sun is moſt ſplendid in it ſelf,
and
ſo are the fixed Stars.
The ſix Planets do abſolutely
want
light, as the Earth; therefore their eſſence agreeth with
the
Earth, and differeth from the Sun and fixed Stars.

is the Earth moveable, immoveable the Sunne and Starry
