5139That the Moon may be a World. agreed on by the General Conſent of the moſt,
and the beſt Philoſophers.
1. It is Solid, in Opoſition to Fluid, as is the
for how otherwiſe could it beat back
the Light which it receives from the Sun?
But here it may be Queſtioned, whether
or no the Moon beſtow her light upon us, by
the Reflection of the Sun-beams from the Su-
perficies of her Body, or elſe by her own illu-

Places, whereas thoſe Bodies which give
Light by Reflexion, can there only be percei-

to the Angel of Incidence, and this is only in
one place, as in a Looking Glaſs, thoſe Beams
which are reflected from it, cannot be percei-

Wherefore ’tis as well the
more probable, as the more common Opini-
on, that her Light proceeds from both theſe
Cauſes, from Reflexion and Illumination;
nor doth it herein differ from our Earth, ſince
that alſo hath ſome Light by Illumination:

for how otherwiſe would the Parts about us
in a Sun-ſhine Day appear ſo Bright, when as
the Rays of Reflexion cannot Enter into our
