@farmerman,
The atheist starts out with contrasting common sense against religion, ridiculing religion with common sense. There is still a lot of acceptance of subjectivity in common sense. But when the atheist starts to systematically think things through, then the atheist systematically excludes all spirit, including the human spirit, and not just God the holy spirit. At this point the atheist comes to reject subjectivity whole, and reject free will is real.
philosophy 101:
The spiritual domain can be explained logically as follows: what is free can only be identified in a free way.
Love and hate are free, they are motivation of a decision, they choose.
Measuring works by cause and effect, evidence of something forces to a conclusion, resulting in a fact, which fact is a copy / model of what is evidenced. The fact of the existence of the moon, is a model of the moon, which model points to the moon itself. The moon is the cause, and the fact of it's existence is the effect of that cause.
Love and hate are free, therefore you cannot get any evidence of them, because evidence works by force.
But that there is no evidence of love or hate is not a problem, because you can just make an opinion about it. With opinions you reach the conclusion by a way of choosing it. So you can make opinion on whether a decision was made out of love or hate. Everybody is born with a very sophisticated capability to form opinions in many different ways.
The universe can turn out several different ways, which means the way it turns out is chosen. You can then make opinion on the motivation of these decisions, whether it is out of hate or love.
So there is the spiritual domain which chooses the way the material domain turns out. The existence of all in the spiritual domain is a matter of opinion, and the existence of all in the material domain is a matter of fact.
The human body / brain, is organized in terms of decisionmaking. It has an inherent structure for choosing. Being a slave is therefore against the nature of people. And being a slave to evidence, to require to be forced to a conclusion on every issue, is slavery in a very real anti-human, emotionally disturbing sense. We have freedom of opinion for what is in the spiritual domain, and only for what is in the material domain is it required to be forced by evidence to a conclusion.
