Re Energy:
Georgina,
You've got it all dreadfully mixed up again.
Energy (and position etc.) are FULLY COVERED by the law of nature relationships, i.e. they are fully representable by equations, i.e. there's nothing more that can be said about them.
But you are claiming that energy is somehow MORE than a thing that can be represented by an equation.
If you want to claim that energy is MORE than a relationship, MORE than a thing that is represented by an equation, then you are implying that energy is a voodoo entity with a personality.
You've got your mathematics mixed up. You have mixed up categories (like energy and position) with numbers. Categories are represented by variables and equations; categories are not numbers; numbers are not categories.
The actual issues are:
1) It is NECESSARY that the world moves itself. What aspect of the world is assigning the numbers that apply to the categories? Examples of categories are position and energy, things that are represented by variables and equations.
2) What is a number? Mathematically, real-world numbers can only be relationships, just like the laws of nature are relationships, but numbers are relationships where the numerator and denominator categories cancel out, leaving a thing that has no category.
3) It is NECESSARY that a differentiated world can differentiate (discern difference in) itself. What aspect of the world differentiates (discerns difference in) the aspects of the world that we would represent by equations, variables and number symbols?
