Philosophers and legal theorists still disagree about the correct analysis of `rights', both moral and legal. The `Will Theory' and the `Interest Theory'--the two main views--can each account for various features of rights, but neither of them is totally satisfactory. The controversy has now been running for decades and seems irresolvable. I will contend in this paper that the discussion of `value pluralism' in the Berlinian tradition can illuminate the debate over the concept of rights.
