uhhh well I would tell you to watch the video of Sam Harris discussing it because that's what really sold me. I disagreed and argued vehemently against crashband that we did have free will before accepting defeat after watching that video.
I guess how I see it is that we do have the choice to do what we want but we don't decide what we want. Our brain creates thoughts and then we observe the thought and then act. Thinking is the limit of what we can do and we can't control our thoughts because that would…require thought. If that makes sense. Basically you have as much control over your thoughts as you have control over your heart beating or your body making white blood cells or your digestion system.
