[8] Nevertheless, though of tall tales of such a kind and number they have shouldered and lugged in not a wallet-full, by heaven, but some juggler’s pack and hotchpotch, still they say
1
that others are playing the buffoon by placing the moon, though it is earth, on high and not where the centre is. Yet if all heavy body converges to the same point and is
compressed in all its parts upon its own centre,
2
it is no more as centre of the sum of things than as a whole that the earth would appropriate to herself the heavy bodies that are parts of herself; and [the downward tendency] of falling bodies
3
proves not that the [earth] is in the centre of the cosmos but that those bodies which when thrust away from the earth fall back to her again have some affinity and cohesion with her.
4
For as the sun attracts to itself the parts of which it consists
5
so the earth too accepts as [her] own the stone
6
that has properly a downward tendency, and consequently every such thing
ultimately unites and coheres with her. If there is a body, however, that was not originally allotted to the earth or detached from it but has somewhere independently a constitution and nature of its own, as those men
7
would say of the moon, what is to hinder it from being permanently separate in its own place, compressed and bound together by its own parts? For it has not been proved that the earth is the centre of the sum of things,
8
and the way in which things in our region press together and concentrate upon the earth suggests how in all probability things in that region converge upon the moon and remain there. The man who drives together into a single region all earthy and heavy things and makes them part of a single body — I do not see for what reason he does not apply the same compulsion to light objects in their turn but allows so many separate concentrations of fire and, since he does not collect all the stars together, clearly does not think that there must also be a body common to all things that are fiery and have an upward tendency.
