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
