Let’s say you see someone playing in traffic, and tell them they shouldn’t be doing that. They respond, “I can’t not do it, because my brain already made the decision to do it, so I have no choice but to do it.”
Is this person correct? Or do they have the ability to just follow your advice and stop playing? Do they have the ability to ignore your advice and keep playing? If they have the ability to do both, then to what degree can we say that your advice is determining their choice? How can we say that choice is determined if we can also say that they should make a different choice?
