Like many other Dworkin's writings, this is dense and difficult in the extreme. His writing style takes immense patience to parse, and I for one was frequently confused about what he was saying. It took me several days, on and off, to understand his recent (and posthumous; Ronald Dworkin died on February 14, 2013.) article in the New York Review of Books "Law from the Inside Out", November 7, 2013. He asks, "What is law?" He then proceeds to describe contemporary definitions such as "legal positivism" and why they fail. He proposes his own interpretive theory of law.
He asks an important question though: can moral claims be true or false? His opponents, the anti-realists, say no, because judgments about moral rights and duties cannot be empirically tested. Instead, they say these judgments are really only recommendations for conduct, and that nothing we say about the law is true or false. He gives an excellent counter-example: "A judge who sentenced a defendant to jail while admitting that [his own] view of the law is only an emotional expression would probably be sent to jail himself."
Dworkin argues that there is actual truth in morality and politics and therefore in law. What is this truth, he asks, to questions about what is justice, liberty, equality, democracy? In a key quote he asserts, "It is crucial to establish that there are, in principle, better and worse answers to these questions, and therefore a best answer, and therefore a true answer."
He therefore proposes two fundamental principles that underlie the search for these truths:
First, that it is objectively important that each and every human life succeeds rather than fails, and that this is important from everyone's point of view.
Second, that each person has a fundamental, inalienable, responsibility to take charge of his or her own life: that it is finally up to that person to decide what living well would mean and to pursue that life.
Is this view elitist and unrealizable for most people? In his latest book, "Justice for Hedgehogs", Dworkin argues "that people in radically different economic and cultural situations can recognize that their lives are important and can recognize what their own responsibility to live well, in their own circumstances, means."
