As I said, science is painfully at a loss to define it's source.
When discussing science it is best to drop certain emotive phrases.
"Painfully at a loss" implies something which isn't the case.
As if we're desperate to find a scientific explanation but just can't, there by exposing some flaw in science.
It would be better to say the much more bland "We don't know yet".
Even if we did it is like taking a ruler to measure how sexually attractive the opposite sex is. You may get results but they won't mean much.
You don't know that. For all intensive purposes we might obtain a fully deterministic model of consciousness.
I have chosen to describe us as a force. What better approach for science?
Force is a poor word choice as force is already defined as the change of momentum over time.
A better word would be "causal agent" or something similar.
You seem convinced that the human mind can't be understood completely by science, where as this is may not be case.
For now all we can say is that science has not advanced to the point where it can model the human mind, if it is even capable of doing so.
