It's interesting that the path from 'decide to do something' to performing the action is hundreds of ms long. It's also interesting that grabbing the data early in the process and acting on it can perform the action before the conscious 'self' understands fully that the action will take place. It's just another reminder that the 'you' that you consider to be running the show is really just a thin translation layer on top of an ocean of instinct, emotion, and hormones that is the real 'you'.
I rather prefer the holistic take that we are our whole selves and not just the part that reflects on what we do or the part that reacts to external and internal material stimuli. We know we can change the instincts, emotions, and hormones when they conflict with what we know by reflection to be just and good. To put it another way, we know that we can do things "without thinking" that are either just or unjust and by reflection can achieve some level of mastery over the direction of our impetuses.
