Certainly I do not "lack free will" if that means I am in jail, or never uncertain of my future decisions, or in a brain-state where my emotions and morals fail to determine my actions in the usual way.

which seems to me to contradict the one before, as it expands the definition to include every possible human mind-state.

I don't know what E's sentence is doing there, to the point that I suspect it's been garbled by an editing error. But I don't see why "having free will" should not include pretty much all mind states, short of being asleep or abnormalities such as drug addiction. The phenomenon he is pointing to, whatever its name, is something that human minds do.
