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