Neuroscience is a newcomer to the field of free will. What are exactly the kind of questions that are worth asking? What different kinds of experiments that can say something about conscious and unconscious decisions can help us be more modest in what we realize we can control, and what we can't? Generally, humans have a sense that they control themselves and sometimes their environment more than they do.
The question of whether we are free to act compels us to accept that there are different degrees of determinism and that even freedom and causality might be compatible. That was already announced by Saint Augustine, for whom divine providence did not preclude free will. An incompatible position, in which determinism excludes true freedom, could hardly be reconciled with such indisputable phenomena as spontaneity, repentance, rebellion, or resistance, and the capacity for the future, which only finds their place in freedom.
