That the Earth may be a Planet.
thing, becauſe it was ſo in one thing: And
this would be an excellent Argument to prove
that Opinion of Anaxagoras, that the Snow
was black.
The reaſon why that motion which is
cauſed by the Earth, does appear as if it
were in the Heavens, is, becauſe the ſenſus
communis, in judging of it, does conceive
the Eye to be it ſelf immovable, (as was
ſaid before) there being no ſenſe that does
diſcern the effects of any motion in the Bo-
dy;
and therefore, it does conclude every
thing to move, which it does perceive to
change its diſtance from it:
So that the
Clouds do not ſeem to move ſometimes,
when as notwithſtanding they are every
where carried about with our Earth, by ſuch
a ſwift revolution;
yet this can be no hin-
drance at all, why we may not judg aright
of their other particular Motions, for which
there is not the ſame reaſon.
Though to a
Man in a Ship, the Trees and Banks may
ſeem to move;
yet it would be but a weak
Argument, to conclude from thence, that
therefore ſuch a one could not tell whether
his Friend does really ſtir, whom he ſees to
walk up and down in the Ship:
or that he
might as well be deceived in judging the
Oars to move, when they do not.
’Tis again replied by the ſame Objector,
That it is not credible, the Eye ſhould be
miſtaken in judging of the Stars and Hea-
vens;
becauſe thoſe being light Bodies, are
the primary &
proper Objects of that Senſe.
