You said: "[A] physical part of you makes the decisions, but it doesn't happen consciously." Right. We agree on this. We seem to disagree on the implications. In my view, you choose the inputs, you choose to decide, and you decide. The fact that you can't see how you get from inputs to decision is because you are using a neural network to get the answer, not because you don't have free will. You may or may not have free will, and the process would be the same.
You said, "Training and learning make a difference which is why the belief that free will is an illusion doesn't mean that we shouldn't try. Instead it should make us less arrogant and more compassionate because we didn't choose our atoms and neither did anyone else." The underlined words imply that we have choices...to learn...to try to improve ourselves...to be less arrogant and more compassionate. This is where we are not communicating. You keep saying we have no free will, but you say things that imply we should choose to improve ourselves, which is an act of will. If I were destined to improve myself, you would not need to convince me. And if I were destined not to improve myself, your attempts to convince me would be fruitless, so why try?
If I remember correctly from the first video you embedded (which I watched late last night, but found to include almost nothing about free will), the Rabbi indicates that Harris's very attempt to try to convince the Rabbi implies that free will exists. Harris just dismissed the argument without substantive response, and went on an anti-religious diatribe. And yet, the point remains. Harris wants to convince people they have no free will because it will change their lives for the better...but what does "want" mean in the absence of free will?...and how will their lives be "changed" if there is no free will? It certainly seems like Harris wants to give people a chance to make decisions that they would not otherwise make if they were not convinced of his arguments. But that implies that those people have free will to change, does it not? What am I missing?
