Under homeostasis, a nice point can be made. Often, we can adjust back to homeostasis by movement or by internal physiology. If we are too hot, we can move into the shade or we can perspire. In numerous cases of adjusting back to homeostasis levels, we have a choice of behavioral or physiological adjustment.
This raises the free will question to me. If I walk to the apple tree, is that a freely willed choice? I also thought so. I could contravene it – maybe choose a further oak tree deeper in the woods. But there is a reason I’m picking shady spots, tied to a physiological need, not to a philosophical decision.
A case where reasoning and choice are linked to decision-making. It feels like free will but is not divorced from physical reactions.
