How could Newton compute orbits with this occult quality he called force?
Nature is not occult.
But the occult has always been a part of scholasticism in the form of occult causes and dormitive virtues the doctors of philosophy used to explain their doctrines. Scientific tradition that started with Galileo discredited these scholastic occult causes and we no longer accept the occult as a motion causing agent.
If we believe as scientists that occult does not exist in nature we must conclude that Newton could not have used the occult force in his operational formulas to compute orbits.
If we look at Newton’s computations we see that indeed there are no force terms in his computations. Newton used a sophisticated deceit weaved around Kepler’s Rule to establish himself as the new master of European Scholastic tradition.
There are no force terms in operational formulas used to compute orbits. This proves that orbits are not physical, forceful or matterful but geometric and densytic.
