Nick, I don't understand what you mean by random. There is nothing in the slightest random (as I understand the term) in the scenario I gave. The primary difference between the two cases is that in one case you believe you are effecting action via your conscious thoughts (but you aren't) and in the other you do not believe you are effecting action via your conscious thoughts. In both cases, your actions are fully determined by what is going on in your brain; it's just that your conscious thoughts are irrelevant to what happens (and you are deluded about this in one of the two scenarios).
