Dear Sir,
Your statement: "properties must exist in isolation" can be viewed from two different perspectives. First let us define property. Since everything has come from the same primordial stuff, there must a commonality in all, which is not directly evident. That means, during recombination, the same stuffs combined in different proportions due to inertia and conservation laws (we have shown the detailed mechanism elsewhere), which shows a particular combination as different from other combinations. We label such different combinations and call it property. In that way, we can label different properties, which are concepts that can have independent existence of its own without linking it always to material objects. But when we look at any object, we always link that concept to the observed behavior of the object. In that case, properties cannot exist without objects.
When a property exhibits itself, it implies a specific combination of mass and energy that is locally stable, but really unstable. It is because if it is absolutely stable, then it will not interact - not even radiate - to be perceived. If it is locally unstable, then we cannot label it. This combination of stability-instability leads to its interaction with other bodies.
In your earlier post you said: "how does electron "know" how to behave? It is because it follows "laws"?" Only causal particles follow laws. Electrons always follow laws: confine positive charges of protons, which is the reason. Thus, its "knowledge" regarding how to behave depends in a mechanical way on the information on positioning of positive charge, which is nothing but causality. Only conscious agents have free will to violate causality, though the effects of such actions are deterministic.
Uncertainty is inherent in the functioning of Nature, because while we have freedom of action, the results are always deterministic based on the totality of forces acting at "here-now" and is not limited to our action alone. However, this concept has been thoroughly misinterpreted and its mathematical format is wrong.
Regarding memory, we have discussed its mechanism in detail in our essay posted on May 31. You are welcome to see it.
