I find that to be the most interesting statement in this thread. Requires more thought than I am willing to invest at this time of night, but it I don't think I completely agree.
"The biological brain has more control over our consciousness than vice-versa."
What is to say that they are not both the same thing? The consciousness can't exist without the physical brain and the realm of neuroscience is far from definitive at this point. Looking at it that way, to say that we do not have choices and that it is mostly a biological response to internal and external stimuli is redundant.
I see the external influences such as the society one, for example, conditioning people to be a certain way. To accept or reject different concepts as "right" or "wrong". More basic lifeforms are also conditioned by their own environments be it at the individual level or colony level which I think plays out as a form of "society". Perhaps it is redundant to you in light, or lack of, information from neuroscience. However I see many of the same responses in humans mirror those within lower life. More complex responses from increasingly complex life forms. Granted we do not understand how the "mind" work in depth but that does not mean one should withhold their opinion. Even using our basic understanding we have developed medication for chemical imbalances to psychiatric methods. Although I concede it is only an opinion and not an absolute.
"The biological brain has more control over our consciousness than vice-versa."
This wasn't about the two are separate or that the consciousness does not depend on the brain. The point was that often our instincts override our conscious state. Rage or anger issues such as road rage. Flight or fight impulses. Our subconscious and dream-states. The capability to "bury" memories of tragic events or even positive events from our past.
