An occult force would simply be something that refuses explanation. You will see a lot of this in homeopathy where the catch-cry is often “we don’t know how it works, it just does. Stop asking questions.”
This is exactly what physicists say about Newtonian gravity.
Physicists say Newtonian mechanics works therefore shut up have faith and stop questioning Newton’s sacred authority. This is how physicists reason. They accept Newton’s authority without asking questions.
I say this is wrong. Why? Physics is defined as the science that denies the explanation of natural phenomena with supernatural. If you compromise this fundamental rule of physics, no matter how small, you are no longer doing physics, you are practicing shamanism. Unlike physicists, I am not bound by Newton’s authority and I question Newton’s authority.
Newton’s force is an occult quality invented by Newton. Newton claimed that by using this occult quality he correctly computed orbits. But occult does not exist, therefore, Newton is lying. Simple as that.
It takes courage to defend the axiom of physics against Newton’s sacred authority. No physicists can dare question Newton’s authority and hope to remain a practicing physicist.
All you have to do is to uphold the axiom of physics (occult is supernatural) over Newton’s authority (supernatural is natural). Then you’ll know that Newton could not and did not use an occult force in his computations.
Your reasoning is the official physics party line and it goes like this:
Newton’s authority cannot be questioned, if Newton says he computed by using an occult force, then, Newton is right, we can only admit that Newton used an occult force to compute orbits correctly but we don’t know how this occult force works. We cannot question any further than what Newton told us.
This type of scholastic argument by authority is not surprising to me because physicists are the modern continuation of the academic scholasticism. They are direct professional descendents of scholastic doctors who refused to look through Galileo’s telescope.
How did Newton compute orbits if not by using force? Now you know the answer. Newton did not use occult force in his computations because force is occult and it does not exist.
