among the very men who do not recognize a sphærical motion of the earth;
since not even they can easily clear themselves from many difficulties,
which necessarily follow from the daily motion of the {v} whole sky. For in
the first place it is against reason that that should be effected by many
causes, which can be effected by fewer; and it is against reason that the
whole sky and all the sphæres (if there be any) of the stars, both of the
planets and the fixed stars, should be turned round for the sake of a daily
motion which can be explained by the mere daily rotation of the earth. Then
whether will it seem more probable, that the æquator of the terrestrial
globe in a single second (that is, in about the time in which any one
walking quickly will be able to advance only a single pace) can accomplish
a quarter of a British mile (of which sixty equal one degree of a great
circle on the earth), or that the æquator of the _primum mobile_ in the
same time should traverse five thousand miles with celerity ineffable; and
in the twinkling of an eye should fly through about five hundred British
miles, swifter than the wings of lightning, if indeed they maintain the
truth who especially assail the motion of the earth). Finally, will it be
more likely to allow some motion to this very tiny terrestrial globe; or to
build up with mad endeavour above the eighth of the fixed sphæres those
three huge sphæres, the ninth (I mean), the tenth, and the eleventh, marked
by not a single star, especially since it is plain from these books on the
magnet, from a comparison of the earth and the terrella, that a circular
motion is not so alien to the nature of the earth as is commonly supposed.
Nor do those things which are adduced from the sacred Scriptures seem to be
specially adverse to the doctrine of the mobility of the earth; nor does it
seem to have been the intention of Moses or of the Prophets to promulgate
any mathematical or physical niceties, but to adapt themselves to the
understanding of the common people and their manner of speech, just as
nurses are accustomed to adapt themselves to infants, and not to go into
every unnecessary detail. Thus in Gen. i. v. 16, and Psal. 136, the moon is
called a great light, because it appears so to us, though it it is agreed
nevertheless by those skilled in astronomy that many of the stars, both of
the fixed and wandering stars, are much greater. Therefore neither do I
think that any solid conclusion can be drawn against the earth's mobility
from Psal. 104, v. 5; although God is said to have laid the foundations of
the earth that it should not be removed for ever; for the earth will be
able to remain evermore in its own and self-same place, so as not to be
moved by any wandering motion, nor carried away from its seat (wherein it
was first placed by the Divine artificer). We, therefore, with devout mind
acknowledging and adoring the inscrutable wisdom of the triune Divinity
