The Paradox of Free Will

We think of ourselves as possesing free will, which should mean that we have the ability to act freely. However as I have often pondered and as this book discuses, our actions and/or our consiousness is an accumilation of past expiriences which in turn determine the choises we make, therefore we do not in fact have "free will". Even if our choices were not a direct rersult of judgment of our past expiriences, our actions would be more random than free, making it impossible to poses free will. For example if I choose to lift my left arm, the actual lifting of the arm itself is a result of various neurological impulses traveling to and through my arm and my cerebellum, scientifically speaking, the impulses happen a fraction of a milisecond before I would actually choose to lift my arm (which would be a paradox in of itself) therefore analyzed at a more detailed level, "free will" as defined remains not only incalculable and unmeasurable, but impossible either way.
