Finnis, a critic of legal positivism states that "For a judge and for a lawyer trying to track judicial reasoning, the law has a double life". The first life is a.) "its existence as the sheer fact that certain people have done such and such in the past and that certain people now have such and such dispositions to decide and act" and the second being b). "its existence as standards directive for the conscientious deliberations of those whose responsibility is to decide according to law" What do you think the he means by this statement?
