That the Moon may be a World.
Nor may we think that the Earth's Shadow
can Cloud the proper Light of the Moon from
Appearing, or take away any thing from her
Inherent Brightneſs;
for this were to think a
Shadow to be a Body, an Opinion altogether
misbecoming a Philoſopher, as Tycho grants
in the fore-cited place, Nec umbra terrœ corpo-
reum quid eſt, aut denſa aliqua ſubſtantia, ut Lu-
nœ lumen obtenebrare poſſit, atque id viſui noſtro
prœripere, ſed eſt quœdam privatio luminis ſola-
ris, ob interpoſitum opacum corpus terrœ.
Nor
is the Earth's ſhadow any Corporal thing,
or thick ſubſtance, that it can Cloud the
Moons Brightneſs, or take it away from our
Sight;
but it is a meer privation of the Suns
Light by reaſon of her Interpoſition of the
Earth's Opacous Body.
3 If ſhe had any Light of her own, then
that would in it ſelf be either ſuch a ruddy
Brightneſs as appears in the Eclipſes, or elſe
ſuch a Leaden Duskiſh Light as we ſee in the
Darker parts of her Body, when ſhe is a little
paſt the Conjunction.
(That it muſt be one
of theſe, may follow from the Oppoſite Ar-
guments) but it is neither of theſe;
therefore
ſhe hath none of her own.
1. ’Tis not ſuch a ruddy Light as appears in
Eclipſes;
for then why can we not ſee the
like redneſs, when we may diſcern the Ob-
ſcure parts of the Moon?
You will ſay, perhaps, that then the near-
neſs of that greater Light takes away that Ap-
pearance.
I Reply, this cannot be; for then why does
Mars ſhine with his wonted Redneſs, when
