If I am not in command of my own brain…who or what is?
Well that depends on what you mean by the ‘I’ in “If I am not…”. There may be only one person when you look in the mirror, and that person may have a single consciousness (though some theories of consciousness may argue that there is nothing singular about it – a subject for another day). The consciousness is the bit of you that you are aware of, that you are able to experience and control. If you decide to pick up a spoon, this is the bit that makes that decision, and gives the order to reach towards the spoon. But what about coordinating all those tiny subtle muscle movements in the right order to reach and grasp the spoon. Who is controlling those? Unless you are an infant, or recovering from an injury, it probably is not the conscious you. That would be exhausting. Hidden parts of your mind are taking care of these learned behaviours.
What if, as you were reaching for the spoon, a notification pinged on you mobile phone, located a little closer to you than the spoon? Your attention would shift, and you would just have to glance to see if the screen told you anything enticing. If it does, you might abandon the spoon and pick up your phone, or you may shrug and carry on. Either way, something, that was not the conscious you, became aware of the phone, interrupted your current task in the spotlight of attention, and stuck itself in the way. It’s possible you might forget you were ever after that spoon at all. It’s trivial example, but I’m making the distinction between bottom-up awareness, driven by your automatic brain with its basic drives, and top-down processing from your conscious, goal-focussed mind. Along the way I am highlighting the fact that You are much more than the single conscious experience that you are aware of moment to moment, and that you have direct, voluntary control over.
