> 1. Humans evaluate, determine, and select which causal effects to attempt/apply, among the selections in their known agency.
Explain this process in the framework of physics and thermodynamics. Specifically, what differentiates this free will process from mere causal process?
Humans determine their actions (will) where fate (determinism) isn't prescriptive of their course. Humans don't have a monopoly on will, but we do have our own. If you've ever survived, it's because you chose to eat. Eventually, even decisions like these which you may feel are implicit are also subject to be reversed if we want to and will.
