This is totally irrilevant; in fact there is no reason to expect that electromagnetic interactions must be the only interaction existing in nature; gravity and nuclear interactions also exist in nature.John Hammond wrote: I think you actually pointed out that QED does describe only a limited part of nature, since it does not describe gravity or nuclear forces.
The point is that the laws of physics ARE only abstract mathematical equations; so your argument does not stand. The laws of physics are intrinsically abstract concepts. As I have written in my previous message, try to explain which concrete entity is represented by a Schroedinger equation.John Hammond wrote:
Second, I did not say that the laws of physics were human representations; I said that abstract mathematical equations are humanly created symbolic representations, some of which appear to describe behavior in nature quite well and so are useful as symbolic proxies for, or representations of, the laws of physics.
Since no man can alter the laws of physics or catch God in the act of doing that, the only possible way to prove that the state of the universe is determined by some specific mathematical equations is to find a systematic agreement between experimental data and theoritical predictions; this is what we would expect if the state of the universe was determined by some mathematical equations and this is what we have found. If you reject this position, you are totally unable to account for our capacity to predict systematically experimental data through a specific system of mathematical equations.John Hammond wrote: In order for science to have proved that abstract mathematical equations determine behavior in nature, some scientist would have to demonstrate that altering one of these equations *causes* the alteration of some corresponding part of nature (or catch God in the act of doing this).
You have missed my point: The necessity of the existence of a conscious and intelligent God is a consequence of the intrinsic abstract nature of the laws of physics.John Hammond wrote:
However, the more important question which has so far gone ignored in this discussion is the question concerning the origins of physical order and laws—mathematical or otherwise—and the necessity of such laws to have a law-giver (e.g. God at his whiteboard writing down the equations which determine the laws of nature): If we demand the existence of a conscious Being as Creator to explain the order we observe in nature, then why does not the same demand apply to explain the existence of the Creator?
