Firstly, if there is nothing ‘supernatural’ about the brain, then we have no free will, since if our thoughts are simply an anomaly of the physical laws, then they are unfree. Randomness i.e. Heisenberg, does not enable free will since randomness has no meaning and though unpredictable randomness does not ‘choose’ by definition [though some may claim that ‘God’ chooses in which case our minds would be controlled by ‘God’] and is therefore unconscious.
Imagine this paradox. [though some may have seen this before]
A ‘choice’ is free by definition, since if your actions are predetermined or forced then they are not chosen.
In order to make a choice, you must have a reason for doing so or else you are acting on instinct/subconsciously. And this reason, must itself be reliant on other reasons since a reason that has arisen from no reasons is ‘unreasonable’ or impossible.
And yet if all of our ‘choices’ are made because of reasons which are in turn reliant on other reasons which are then in turn reliant on more reasons, etc Then how are our choices free since all things happen for reasons over which we have no control?
There are only two possibilities. 1 [which requires faith] a dogmatic assumption. 2 There is no such thing as choice.
The dogmatic assumption may take the form. God makes it possible for us to have free will, and it is beyond us to understand how.
But one might ask the question, why should I believe that? to which the dogmatist will have no rational explanation.
