, Query XVII:
. . . Government is just as infallible too when it fixes systems in physics. Galileo was sent to the inquisition for affirming
that the earth was a sphere: the government had declared it to be as flat as a trencher, and Galileo was obliged to abjure
his error. This error however at length prevailed, the earth became a globe, and Descartes declared it was whirled round its
axis by a vortex. The government in which he lived was wise enough to see that this was no question of civil jurisdiction,
or we should all have been involved by authority in vortices. In fact the vortices have been exploded, and the Newtonian principle
of gravitation is now more firmly established, on the basis of reason, than it would be were the government to step in and
to make it an article of necessary faith . . .
René Descartes, 1596-1650, French philosopher. The first edition of this work was printed by Elzevir in 1644. A number of books have been
written not only in explanation of the Cartesian philosophy, but also in comparison of the philosophies of Descartes and of
Sir Isaac Newton.
