Creation of the universe isn't necessarily generation of new energy, it is simply the breaking of equilibrium. There are two "basic" possibilities: case 1: energy and physical laws have existed for all time in their present state, case 2: energy and physical laws were created at the time of the big bang.
In order to be in camp 2, you are forced to admit that some OTHER laws were in existence for all time, because something had to start the big bang and create matter and antimatter from a previous state -- something not abiding by modern laws of science.
Quote:The second is awareness. By manipulating energy, it is fundamentally possible to create an arbitrarily complex machine capable of doing practically anything -- where "doing" is defined by manipulating the energy state around it. But being aware of oneself cannot, at present, be defined by any set of particles.
Quote:Why could a machine not become aware of itself, if it had the requisite circuits?
It is obvious that a machine CAN become aware of itself given the requisite circuits. All you have to do is assembly a bunch of particles into the configuration of a human brain, and it will become conscious. This is an undebatable fact, evidenced by humanity.
Quote:Awareness is probably not a "set of particles" but may arise from patterns of electrical impulses zipping around in the brain at various frequencies.
Awareness is not a set of particles. Like all phenomena, it is a result of interactions between particles or other fundamental quanta (or perhaps I should just say "things" because quanta may be too restrictive). Yes, it may very well arise from specific patterns of electrical impulses at various frequencies....
You're really not getting it, are you? Imagine that particles have only 2 states; speed and position. There is also a set of laws associated with the space. These laws therefore only operate on speed and position. Therefore, they can only describe speed and position. Now we have a red particle and we project it into this space. The color red is ignored. A blue particle also is projected into this space and its color is ignored. The laws of this space only deal with speed and position. Since the space has no representation for color, it is impossible for those laws to explain color. Now, it may very well be the case that color is related to speed and position. For example, color could be related to the distance between particles in the system.
Now let's look at something more familiar, like LIGHT. Go back to the time before we knew that the perception of light was the absorption of photons which are quantized particles that travel in waves and are absorbed, reflected, etc. Before they knew about light, they knew about speed and position of particles. They could use their laws of physics to describe what would happen to a baseball when hit by a bat. But they would come up with the same answer regardless of whether or not there was a flashlight shining a beam of light at the bat. To them, light was not representable in their system, so it was ignored when they projected it into the dimensionality that they could represent ; position and velocity.
Awareness is created by particle interactions in the brain (fact), but we don't know how to represent awareness in a system defined by: position, velocity, acceleration, momentum, charge, spin, time. Until we can define the relationship of awareness to these states, or to possibly additional states or additional particles, awareness CANNOT be explained by physics.
This is not to say that laws defining awareness do not EXIST. Clearly, they DO exist, because awareness exists. But we dont know how -- and you cannot include unknown laws as part of "scientific laws" because science refers to the current set of known laws, not to the ideal future perfect set of laws.
Quote:I don't know that most people would agree. I certainly wouldn't. I think that my decisions come from neural networks which add and subtract neurons (links to memories and senses) and are moderated by biochemical feelings until a decision is reached.
It sounds like you are confusing ANN's with NN's. There is a huge, huge, difference here. A real neural network is a brain. We dont really understand the brain. An artificial neural network is a pathetically weak abstracted network that encapsulates only the concept of neuron interconnectivity and positive/negative feedback as an iterative solution to gradient descent. I write and use ANN's in my work too, but I am not deceived about their capabilities. You can write a computer program where a bit of information represents whatever you want -- a memory, a sense, an emotion -- but that doesn't make it real.
Quote:I don't think it is possible - or necessary - to pull decisions from some mythical external field, although other people and events may affect your final decision.
Really...so...does this mean you can also deduce the color of a particle from mathematical laws defined in a system that lacks a representation for color? Because it is exactly the same.
Quote:How is free will a violation of modern physics? Surely quantum uncertainty applies here.
No, quantum uncertainty absolutely does NOT apply here! Quantum physics model the system as being perfectly random below some level, and they are able to use statistics to make predictions at higher levels based on that. Free will requires a lapse in determinism because it requires a person being capable of making a choice as opposed to their actions being 100% predictable based on their experiences (eg, the matter/energy in their brain). Quantum physics also requires a lapse in determinism because it uses randomness -- but free will does not say that your choice is random, it says that your choice is decided by your awareness. This, of course, is difficult to describe because "choice" and "awareness" are dimensions that currently have no representation in terms of physical particles...which is exactly why choice/awareness cannot be predicted by physical laws!
