Interesting. I agree that within the material energy there is no free will. One action brings a reaction which is also an action which brings another reaction and so on in a chain of events. This can be studied and documented. Tested and proven. No free will there.
On the level of consciousness there is however free will. I "can choose" how I see myself and the world. I can choose to act or react according to my conscious decision.
The trick is to be conscious.
