[143] "_Copernicus._ If by chance there shall be vain talkers who, although
ignorant of all mathematics, yet taking it upon themselves to sit in
judgment upon the subject on account of a certain passage of Scripture
badly distorted for their purposes, shall have dared to criticize and
censure this teaching of mine, I pay no attention to them, even to the
extent of despising their judgment as rash. For it is not unknown that
Lactantius, a writer of prominence in other lines although but little
versed in mathematics, spoke very childishly about the form of the earth
when he ridiculed those who declared that it was spherical. Hence it should
not seem strange to the learned if some shall look upon us in the same way.
Mathematics is written for mathematicians, to whom these labors of ours
will seem, if I mistake not, to add something even to the republic of the
Church.... _Emend._ Here strike out everything from 'if by chance' to the
words 'these labors of ours,' and adapt it thus: 'But these labors of
ours.'"
[144] "_Copernicus._ However if we consider the matter more carefully it
will be seen that the investigation is not yet completed, and therefore
ought by no means to be condemned. _Emend._ However, if we consider the
matter more carefully it is of no consequence whether we regard the earth
as existing in the center of the universe or outside of the center, so far
as the solution of the phenomena of celestial movements is concerned."
[145] "The whole of this chapter may be cut out, since it avowedly treats
of the earth's motion, while it refutes the reasons of the ancients proving
its immobility. Nevertheless, since it seems to speak problematically, in
order that it may satisfy the learned and keep intact the sequence and
unity of the book let it be emended as below."
[146] "_Copernicus._ Therefore why do we still hesitate to concede to it
motion which is by nature consistent with its form, the more so because the
whole universe is moving, whose end is not and cannot be known, and not
confess that there is in the sky an appearance of daily revolution, while
on the earth there is the truth of it? And in like manner these things are
as if Virgil's AEneas should say, 'We are borne from the harbor' ...
_Emend._ Hence I cannot concede motion to this form, the more so because
the universe would fall, whose end is not and cannot be known, and what
appears in the heavens is just as if ..."
[147] "_Copernicus_. I also add that it would seem very absurd that motion
should be ascribed to that which contains and locates, and not rather to
that which is contained and located, that is the earth. _Emend._ I also add
that it is not more difficult to ascribe motion to the contained and
located, which is the earth, than to that which contains it."
