my subconscious mind makes me breath. it also beats my heart.Your autonomic nervous system causes your own body to breathe when you forget to think about it.
the universe is "programmed" to work that way so the atoms simply follow some fairly simple rules.
if two magnets that attract is a natural law, is it also a natural law when a man and a woman are attracted? thoughts cause this attraction in humans, so i think it's also thoughts (subconscious) that cause magnets to attract.
if consciousness controls us, it controls everything. if we are made of matter, everything is made of matter. if god controls natural laws, he controls us too.
There is no need to postulate a consciousness unless you want to get metaphysical and speculate about the "programming."
i would say the opposite: there is no reason to postulate a natural law
but it's all the same... just different perspectives...
