Arguments of

Cœleſtial bodies

SALV. Simplicius, we are here familiarly diſcourſing among
our
ſelves, to inveſtigate ſome truth; I ſhall not be diſpleaſed
that
you diſcover my errors; and if I do not follow the mind of
Ariſtotle, freely reprehend me, and I ſhall take it in good part.
Onely give me leave to expound my doubts, and to reply
thing
to your laſt words, telling you, that Logick, as it is well
underſtood
, is the Organe with which we philoſophate; but as it

from
the reading of Books full of demonſtrations, which are the
Mathematical

Now returning to our
purpoſe
, I ſay, that that which Ariſtotle ſeeth of the motion of
light
bodies, is the departing of the Fire from any part of the
Superficies
of the Terreſtrial Globe, and directly retreating from
it
, mounting upwards; and this indeed is to move towards a
circumference
greater than that of the Earth; yea, the ſame
riſtotle
makes it to move to the concave of the Moon, but that
this
circumference is that of the World, or concentrick to it, ſo
