This is a way to make sense of the concept of free will without contradicting science etc.
You cannot predict the outcome of it, it is highly flexible and it perceives itself as free.
Yet it is caused and bounded by the laws of nature.
It obeys scientific determinism philosophically, but determinism will fail to unravel it.
I don't think there can be any reasonable objection against this view of free will.
The counterargument that this form of free will isn't realy free in the sense that it cannot escape the laws of physics, would in my view be a childish objection since no-one is arguing against the idea that we are bound by the laws of physics anyway.
It's like arguing you can't buy anything with money.
The argument is whether if you accept the laws of physics, there can be a definition of free will that makes sense.
I say there is, as i explained above.
