On the substance dualism But when it happened, it wasn't a conscious decision? Seems very suspicious. — Patterner
I personally don't care if that particular movement was conscious or not. I've come to view conscious decisions as something separated in time from when they're actually realized. I believe the majority of actions are subconscious, and the conscious part of us is almost like a feedback system for our subconscious decision mechanisms.
So imo it's pluasible that your conscious mind has almost no direct control of what your body does, but it can command your subconscious to do it. Most of the stuff your body does doesn't get mediated by the conscious part at all, it's mostly subconscious, but your conscious mind can choose to send immediate commands (which have to be mediated first by the subconscious, and then go to your muscles), or - and this is even more important - can tell your subconscious when it did something wrong, and should do something different the next time a similar scenario arises.
I actually think the point of consciousness is mostly that last thing, somehow signaling to your subconscious to do something different, because your conscious analysis determined it wasn't optimal.
