Free Will Theodicy

[Bucky Ball]

so in reality will is an perceptual illusion.   In principle what we perceive as the working of our will is but an essentially immutable series of causal chains that is exogenous to our mental construct of self.   the only thing that gives us room to imagine it is ours and it is free is we lack the ability to predict its outcome with high precision.

Agree partially 
For a given moment / decision, what the brain references in making a decision has to already be laid down in it's chemistry. One cannot decide to do something 
one has no prior familiarity with. What is going on may or may not be exogenous to a self image. One could decide to specifically act contrary to it, in certain circumstances. 
Free will is a bad label. I don't think neuro researchers use it any more. It was a long road in getting it established that a substantial amount 
of a decision is subconscious, AND the decision is actually made before we are conscious of it, (by a few seconds).
