The Absolute Bedrock Truth of Things

There is a very close connection between this rise of physical and scientific determinism in the 19th century. And it's not that he causes those things to happen but he knows them because he knows exactly their causes which are physical interactions, physical events. The mathematical expression of this is coming into being round about exactly this same time, we now call it the principle of least action. It's an equation which very effectively can be used for any reference system to define the motion of all points and particles within that reference system.
