bodies, and independently of each other and contingently, to meet together in a third entity, the
body. In this way whatever profundity was contained in the thought of general gravitation is
destroyed again, and the concept and reason will be unable to penetrate into the theory of
absolute motion, as long as the vaunted discoveries of forces prevail there.
if one closely considers the quantitative determinations which have been identified in the laws of
the centripetal and the centrifugal forces, one very quickly discovers the confusion which emerges
from their separation. This confusion becomes even greater if the separation is mentioned in
relation to gravitation; gravitation, also called attraction, then seems to be the same as centripetal
