The mind is the embodied system that manages the flow of energy and information.
The will is that which directs the flow of energy and information.
I am a compatibilist. That means that I believe that free will and determinism are mutually compatible. I believe that it is possible to believe in both without being logically inconsistent.
The flow of energy and information is determined, while the directing of that flow is free.
Limited free will, which does not originate the flow but which can direct that flow, is compatible with determinism. The flow is determined, the direction is not.
The Daoists teach us to go with the flow of Nature, the Dao.
