I want you to replace the word, “Choose” with, “React” in every instance of free will one could ever describe. Instead of “choosing” between blue or red, one’s brain reacts in a way that leads to the inevitable result. We are conditioned, and every choice we make is how our conditioning reacts with the environment. When an object reacts to the laws of physics we call it motion, when a self aware object reacts to the same laws we call it free will.
We are programmed by nature to feel the stimulation of free will, which explains why it is counterintuitive to think about human processes in a deterministic way. When a leaf falls to the ground, it has no control over the pattern of its motion as it falls. Every time it glides left to right it is reacting to the air molecules it meets on its descent. You are no more in control of your thoughts and actions than the leaf is of its pattern of motion as it descends to the ground.
We only have one choice; that being to follow the laws of nature.
