In human freedom in the philosophical sense I am definitely a disbeliever. Everybody acts not only under external compulsion but also in accordance with inner necessity.
Environmental influences dictates a subset of necessary actions in order to survive or prosper. And when such elements do not effect, we don't just freely choose whatever we want to do, but act out of the inner desires, impulses, instincts, dictated by the "mighty ruler" within, spoken of by Nietzsche, or the Self, by Jung.
