It is obvious that if there is strict causal determinism, the will is
not
free from strict causal determinism.

Or there is not strict causal determinism

A FW that was constrained always to be strictly logical would not
be all that free.

I think I followed that...no amount of checking
suffices for certainty, but any finite amount is unmiraculous
