Question: How does Free Will manifest itself in human nature?
Answer: Consciousness is a natural, emergent capacity of the brain/mind, and it manifests itself volitionally in three ways, I think. One is the issue of intensity. We all have the capacity to kind of dial up the intensity, so to speak; to let our minds be more relaxed, or sort of thinking or attending to things more with concentrating, so that's under our control.
Another is the range of focus. We can focus in, very tightly on particular things or let our minds, our perceptual capacities also expand out to take in more info, think of the zoom lens on a camera.
The third thing is this issue of initiating action or not. We can think abstractly, imaginatively, in hypothetical mode so to speak. We can also decide to pull the trigger and act on the basis of our ideas.
