2. _Objection to this argument_: Earth is the heaviest body only
by comparison with others; for Earth is itself of different
weights.
3. _Refutation of this objection_: On the contrary, Earth is a
simple body, and as such subject to be drawn equally in every part.
4. _Answer to the refutation, with minor objections and their
refutation._
Since the objection is in itself sound, and
Earth by its own Particular Nature, due to the
stubbornness of matter, would be lower than the
sea; and since Universal Nature requires that
the Earth project somewhere, in order that its
object, the mixture of the elements, may be
fulfilled:
It follows that there must be some final and efficient
cause, whereby this projection may be accomplished.
_a_. The final cause has been seen to be the purpose
of Universal Nature.
_b_. The efficient cause cannot be (i) the Earth,
(ii) the Water, (iii) the Air or Fire, (iv) the
heaven of the Moon, (v) the Planets, nor (vi)
the Primum Mobile:
Therefore it must be ascribed to the heaven of
the Fixed Stars (for this has variety hi efficiency,
as is seen in the various constellations),
and in particular to those Stars of the Northern
Hemisphere which overhang the dry land.
(_x_) _First objection_: Why is the projecting
continent then, not circular, since the
motion of these stars is circular?
_Answer_: Because the material did not
suffice for so great an elevation.
